Sample records for central european passerines

  1. Multiple weather factors affect apparent survival of European passerine birds.

    Directory of Open Access Journals (Sweden)

    Volker Salewski

    Full Text Available Weather affects the demography of animals and thus climate change will cause local changes in demographic rates. In birds numerous studies have correlated demographic factors with weather but few of those examined variation in the impacts of weather in different seasons and, in the case of migrants, in different regions. Using capture-recapture models we correlated weather with apparent survival of seven passerine bird species with different migration strategies to assess the importance of selected facets of weather throughout the year on apparent survival. Contrary to our expectations weather experienced during the breeding season did not affect apparent survival of the target species. However, measures for winter severity were associated with apparent survival of a resident species, two short-distance/partial migrants and a long-distance migrant. Apparent survival of two short distance migrants as well as two long-distance migrants was further correlated with conditions experienced during the non-breeding season in Spain. Conditions in Africa had statistically significant but relatively minor effects on the apparent survival of the two long-distance migrants but also of a presumably short-distance migrant and a short-distance/partial migrant. In general several weather effects independently explained similar amounts of variation in apparent survival for the majority of species and single factors explained only relatively low amounts of temporal variation of apparent survival. Although the directions of the effects on apparent survival mostly met our expectations and there are clear predictions for effects of future climate we caution against simple extrapolations of present conditions to predict future population dynamics. Not only did weather explains limited amounts of variation in apparent survival, but future demographics will likely be affected by changing interspecific interactions, opposing effects of weather in different seasons, and

  2. Central European gas market perspectives

    International Nuclear Information System (INIS)

    This presentation deals with (1) Definition of the Central European market, (2) Factors driving up consumption of natural gas in Central and Eastern Europe, (3) Role of natural gas in regional energy consumption, (4) Position of natural gas in individual country markets, (5) Future sources of imported natural gas into the region. The Central European market are the eleven countries Albania, Bulgaria, Croatia, Czech Republic, Hungary, Macedonia, Poland, Romania, Serbia and Montenegro, Slovakia, and Slovenia, with a total population of 121 million. This market is comparable to combined France and Italy in terms of population, but only 30% of its size in terms of GDP

  3. Feather mites (Acari, Astigmata from Azorean passerines (Aves, Passeriformes: lower species richness compared to European mainland

    2015-01-01

    Full Text Available Ten passerine species were examined on three islands of the Azores (North Atlantic during 2013 and 2014 in order to identify their feather mite assemblages. We recorded 19 feather mite species belonging to four families of the superfamily Analgoidea (Analgidae, Proctophyllodidae, Psoroptoididae and Trouessartiidae. A high prevalence of feather mite species was recorded on the majority of the examined host species. Only three passerine species (Sylvia atricapilla, Regulus regulus and Serinus canaria presented the same full complex of mite species as commonly occurs in the plumage of their closest relatives in continental Europe. Passer domesticus presented the same limited fauna of feather mites living in the plumage as do its co-specifics in continental Europe. Carduelis carduelis bears the same feather mite species as do most of its continental populations in Europe, but it lacks one mite species occurring on this host in Egypt. Turdus merula, Pyrrhula murina and Fringilla coelebs are missing several mite species common to their continental relatives. This diminution could be explained by the founder effect, whereby a limited number of colonizing individuals did not transport the full set of feather mite species, or by the extinction of some mite species after initially having reached the Azores. The only individual of Motacilla cinerea sampled in this study presented a new host record for the mite species Trouessartia jedliczkai.

  4. Associations of forest type, parasitism and body condition of two European passerines, Fringilla coelebs and Sylvia atricapilla.

    Directory of Open Access Journals (Sweden)

    Bruntje Lüdtke

    Full Text Available Human-induced forest modification can alter parasite-host interactions and might change the persistence of host populations. We captured individuals of two widespread European passerines (Fringilla coelebs and Sylvia atricapilla in southwestern Germany to disentangle the associations of forest types and parasitism by haemosporidian parasites on the body condition of birds. We compared parasite prevalence and parasite intensity, fluctuating asymmetries, leukocyte numbers, and the heterophil to lymphocyte ratio (H/L-ratio among individuals from beech, mixed-deciduous and spruce forest stands. Based on the biology of bird species, we expected to find fewer infected individuals in beech or mixed-deciduous than in spruce forest stands. We found the highest parasite prevalence and intensity in beech forests for F. coelebs. Although, we found the highest prevalence in spruce forests for S. atricapilla, the highest intensity was detected in beech forests, partially supporting our hypothesis. Other body condition or health status metrics, such as the heterophil to lymphocyte ratio (H/L-ratio, revealed only slight differences between bird populations inhabiting the three different forest types, with the highest values in spruce for F. coelebs and in mixed-deciduous forests for S. atricapilla. A comparison of parasitized versus non-parasitized individuals suggests that parasite infection increased the immune response of a bird, which was detectable as high H/L-ratio. Higher infections with blood parasites for S. atricapilla in spruce forest indicate that this forest type might be a less suitable habitat than beech and mixed-deciduous forests, whereas beech forests seem to be a suboptimal habitat regarding parasitism for F. coelebs.

  10. The German 'Energiewende' from central European perspective

    International Nuclear Information System (INIS)

    Germany is a country of an exceptional economic significance for Europe and the entire world therefore everything that takes place in this country is carefully analyzed and investigated especially in the Central Europe. Hundreds of thousands workplaces in EU-11 are directly or indirectly connected with German economy present in those countries. That is why an unquestionable revolution in the power sector, i.e. Energiewende, is of importance to us both at present and in the future. The present article presents comparison of installed capacity, generation of electrical energy and power systems in Germany and EU-11. The article also assesses the differences regarding economic development of the aforementioned countries presenting the EU-11's understanding of what Energiewende is and what its objectives are. In addition, the article includes impartial evaluation of problems related to Energiewende and its outcome for the German economy and society. Due to considerable differences regarding economic development, it is hard to imagine a similar revolution taking place in EU-11. Therefore, a compromise with respect to European energy and climate policy acceptable for EU-11, Germany and the entire Europe is of the utmost necessity and the author is convinced that such a compromise is achievable.

    2014-01-01

    Fruits and seeds are critical food sources for many European passerines during the autumn migration, which in turn contribute to disperse seeds either internally, i.e. after ingestion (endozoochory), or externally, when seeds adhere to the body surface (epizoochory). Despite the recognized importance of birds as seed dispersers, the vast majority of studies focused on endozoochory while the external transport of seeds is frequently invoked as being potentially important, but remains ...

  12. Rickettsia helvetica and R. monacensis infections in immature Ixodes ricinus ticks derived from sylvatic passerine birds in west-central Poland.

    The aim of this study was to assess the importance of forest passerine birds in spreading ixodid ticks infected with rickettsiae of spotted fever group (SFG) in sylvatic habitats in western Poland. In total, 834 immature Ixodes ricinus ticks were found on 64 birds of 11 species which were captured during the tick-questing season between May and September of 2006. Ground-foraging passerines hosted most of the ticks compared with arboreal species, and therefore, only the former group was included into a detailed analysis. Significant predominance of larvae over nymphs was observed (581 vs. 253, respectively). Blackbirds and song thrushes hosted 82 % (n = 681) of the ticks collected from all infested passerines. The overall prevalence range of SF rickettsiae (including Rickettsia helvetica and Rickettsia monacensis) in bird-derived ticks was 10.5-26.9 %, exceeding that in questing ticks, and in ticks feeding on rodents and deer reported earlier from the same study area. This high prevalence of infection in immature I. ricinus ticks feeding on passerine birds strongly implies that they are involved in the enzootic maintenance of spotted fever group rickettsiae in the tick vector populations occurring in sylvatic habitats.

  16. THE EUROPEAN CENTRAL BANK AND THE EUROZONE CRISIS MANAGEMENT

    MONICA ŞAGUNA

    2013-05-01

    Full Text Available The Euro is the single currency shared by 17 of the European Union's Member States, which together make up the Euro area. Since its introduction, in January 2002, it became the second most traded currency in the world after the United States dollar. With the launch of the Euro, the monetary policy became the responsibility of the independent European Central Bank, which was created for that purpose, and of the national central banks of the Member States, having adopted the Euro. However, the accumulation of massive and unsustainable deficits and public debt levels in a number of peripheral economies threatened the Eurozone's viability by the end of its first decade, triggering a Eurozone sovereign debt crisis. The institutional mechanisms surrounding the Euro have also been an integral part of the crisis. On this line, the European Monetary Union is supported on one side by treaties and multilateral agreements including the Maastricht Treaty, the Stability and Growth Pact and the Lisbon Strategy and, on the other side, by the European Central Bank. The combination of these institutions has produced a mix of monetary, fiscal and labour market policies with powerful social implications. And, what started as a debt crisis in Greece in late 2009 has evolved into a broader economic and political crisis in the Eurozone and European Union. In this framework, the purpose of my paper is to analyze the roots of the Eurozone crisis, as the biggest challenge since the Euro adoption and the European Central Bank’s response to it. Therefore the objectives are: identification of the reasons that stand behind the crisis, then observing how the crisis has affected the functioning of the European Central Bank and the Euro, and how it was forced to respond and, finally, focusing on the future and the challenges that lie ahead.

    Full Text Available The Dynamics of Trade in Central and Eastern European CountriesAbstract: We describe the evolving pattern of Central European countries’ trade using recently developed empirical procedures based around the classic Balassa index. Despite significant changes in Central European economies during transition to a market economy, the distribution of the indices did not change radically over the 1990s. Our results suggest that the trade pattern converged in Czech Republic, Hungary, Poland and Slovenia, while it polarised in Estonia Latvia, Lithuania and Slovakia over the period. For particular product groups, the indices display greater variation. They are stable for product groups with comparative disadvantage, but product groups with weak to strong comparative advantage show significant variation. At the product level different development can be observed in the changes of trade specialization. The comparative advantages are still based largely on primary and natural resource intensive product groups in the Baltic countries, while CEE5 countries show a successful upgrading process in technological and human capital intensive products.

Our field study of 3 birds species showed that botflies parasitized Troglodytes aedon (25% of nests, but not Sicalis flaveola and Tachycineta leucorroha in spite of nesting in similar boxes, at the same place and during the same time of the year. However T. aedon built nests using dry material while S. flaveola and T. leucorroha used green material. The analysis of published data (35 species considered showed a negative association between botfly parasitism and presence of green material in the nest, and a positive association between botfly parasitism and presence of small sticks in the nest and date of the last nesting attempt during the breeding season. Our results indicate that the materials used to build the nest and the extent of the breeding season are factors that influence host use by botflies in central Argentina.Analizamos el uso de hospedadores de moscas parásitas del género Philornis en una comunidad de aves paseriformes en la región centro de Argentina, así como las características de nidos y hospedadores asociadas con el parasitismo de Philornis.

    Full Text Available In the context of the recent financial crisis, the macroeconomic stability of most countries has been cast to shadow. The damage to the economy caused by high inflation, volatile exchange rates, increasing amount of debts and the unstable financial markets has heavily left its toll on the global market and has led to massive unemployment and increasing poverty. This paper aims to follow the eight new Central and Eastern European countries that joined the European Union in 2004, as well as Romania and Bulgaria, who followed suit in 2007, in what concerns their economical performance, following adhesion to the EU while also comparing the periods before and after the economical crisis. They were chosen as a topic of research for the severity with which the crisis affected them and the high degree of reform implementation in the aftermath. It also plans to highlight the effect of the new reforms and the growth potential when compared to the rest of the European Union. The price inflation, real GDP growth, the levels of (unemployment, fiscal policy and stability of exchange rates will provide a clear image of how this cluster of developing countries fare nowadays against the rest of the EU countries.

    Evolution of salt structures in relation to tectonic events within central part of the Central European Basin System is described by summarizing results which have been obtained and published in frame of the research project DFG-SPP 1135. These results illustrate main phases of salt tectonics within the basin system from the Triassic to present day. During the Buntsandstein and Muschelkalk, extension triggered raft tectonics and salt movements within the Ems Trough, the Glueckstadt and the Horn Grabens. The next phase of salt movements occurred in response to a Middle-Late Keuper regional extensional event which was strongest within the Triassic depocenters of the Central European Basin System, such as the Horn Graben, the Glueckstadt Graben, the Ems and the Rheinsberg Troughs. Regional erosion truncated the study area during the Late Jurassic-Early Cretaceous time. The magnitude of Late Jurassic-Early Cretaceous erosion is declining towards southern margin of the basin system where a dextral transtensional regime was established in the Lower Saxony Basin and neighboring areas during the Late Jurassic-Early Cretaceous. The late Early Cretaceous-early Late Cretaceous is characterized by a relative tectonic quiescence without strong salt movements. The Late Cretaceous-Early Cenozoic inversion provocated renewed salt movements, causing the thick-skinned salt tectonics along the Elbe Fault System and the thin-skinned character of salt movements towards the north from the area of strain localisation. Post-inversion Cenozoic subsidence was accompanied by salt movements, related either to diapiric rise due to regional shortening and/or to local almost E-W directed extension. (orig.)

  14. SUSTAINABLE GROWTH: RECENT TRENDS ACROSS CENTRAL AND EASTERN EUROPEAN ECONOMIES

    Full Text Available What is economic growth? Although the answer to this question may seems of real simplicity, developing an accurate definition of this concept may constitute a real challenge both from a theoretical but also empirical point of view. This constant debate upon the concept of economic growth as well as indentifying the optimum set of instruments for quantifying it, constituted the starting point of the current article. The concept of economic growth is used nowadays complementary to terms like economic development, economic welfare or economic progress with reference to this complex process that implies macro-scale structures. Moreover indentifying the main factors that generate a significant impact upon the dynamics of the economic growth process, constitute a useful approach taking into consideration the high degree of heterogeneity that characterize the architecture of the economies around the world. If we develop this analysis across the European Union member states this debate became even more challenging due to the high degree of diversity that characterize these economies. Moreover, the Central and Eastern European countries and especially the ones that joined EU in 2004 and 2007 embody a set of particularities that make them extremely different from the rest of the European Union member states, features related to the historical background, economic policies and common efforts to intensify the convergence process with the more developed EU members. This paper studies the impact of two main factors upon the economic growth process namely an endogenous-exogenous factor like the degree of openness and an endogenous factor like the human capital using a complex dynamic panel method. The arguments that were in favour of choosing this two factors are on one hand the multitude of theoretical studies that argued the importance of them in modelling the economic growth process and on the other hand the small number of studies that use panel methods in

  15. Gas prices and supply in Central and Eastern European countries

    International Nuclear Information System (INIS)

    The increasing gas significance in the world's energy and economy, as well as overall features of gas industry and trade, call for uniformity of business and development conditions among particular countries and regions. That attracts attention of international institutions, gas companies and particular countries. In this view, also change take place in the Central and Eastern European countries that will have to issue corresponding regulations and implement market conditions in the gas sector as well. One of the basic activities will be a gas policy and price growth, which will enable investments into a new development. Croatia has already started that process due to its dependence on gas imports, which was paid at world prices and on foreign capital. However, as regards the gas sector development, the introduction of market conditions will continue, but at a faster rate and structural changes supply, consumption, property and the like. (author)

    The opportunity cost of inappropriate health policy decisions is greater in Central and Eastern European (CEE) compared with Western European (WE) countries because of poorer population health and more limited healthcare resources. Application of health technology assessment (HTA) prior to healthcare financing decisions can improve the allocative efficiency of scarce resources. However, few CEE countries have a clear roadmap for HTA implementation. Examples from high-income countries may not be directly relevant, as CEE countries cannot allocate so much financial and human resources for substantiating policy decisions with evidence. Our objective was to describe the main HTA implementation scenarios in CEE countries and summarize the most important questions related to capacity building, financing HTA research, process and organizational structure for HTA, standardization of HTA methodology, use of local data, scope of mandatory HTA, decision criteria, and international collaboration in HTA. Although HTA implementation strategies from the region can be relevant examples for other CEE countries with similar cultural environment and economic status, HTA roadmaps are not still fully transferable without taking into account country-specific aspects, such as country size, gross domestic product per capita, major social values, public health priorities, and fragmentation of healthcare financing.

    A number of Lateglacial and Early Holocene lacustrine records from Central and Southern Europe have been shown to contain both visible and micro-tephra deposits, which can be correlated to volcanic eruptions from multiple volcanic sources. Detailed environmental proxy records, which outline local and regional responses to the abrupt climatic changes of the Last Glacial to Interglacial transition (LGIT), are thus constrained within a regional tephrochronological framework. Amongst other volcanic markers, the Laacher See Tephra, erupted from the Eifel region of Germany at 12,880 ±120 varve yrs BP (Brauer et al., 1999), and the Vedde Ash, erupted from Iceland between 12,225 and 11,832 cal. yrs BP (Blockley et al., 2007), are found within some of the same lake cores (e.g., Blockley et al., 2008). These key horizons, which bracket the onset of the Younger Dryas Interstadial, provide precise and absolutely dated tie points around which a detailed picture of the timing of local and regional environmental transitions can be constructed. The presence of the Vedde Ash in the Swiss lake sites allows a direct linkage to the Greenland Ice Core chronology (Mortensen et al., 2005) and highlights the potential for key tephra deposits to be found and correlated across wide geographical areas. This paper summarises the results of tephrochronological investigations into a suite of Central European records, which includes: Soppensee and Rotsee, in Central Switzerland; Rotmeer, in Southern Germany; and Lavarone, in Northern Italy. Chemical analysis of each tephra deposit has been carried out and the sources of the eruption events have been identified. Where appropriate, tephra ages have been transferred from high-precision annually-resolved chronologies and integrated with Bayesian-based radiocarbon age models for the sites. The environmental archives of the LGIT at each site are then compared on a common timescale, and further comparisons are made with other published European tephra

    Full Text Available A variety of Habronematidae parasites (order Spirurida have been described as occasional parasites of avian species; however, reports on passerines are relatively uncommon. From 2007 to 2008, 11 passerine deaths at The North Carolina Zoological Park in Asheboro, NC, USA, were associated with ventricular habronemiasis, which was determined to be the cause of death or a major contributing factor in 10 of the 11 individuals. The number and species affected were 5 Red-billed Leiothrix (Leiothrix lutea, 2 Japanese White-eye (Zosterops japonicus, 2 Golden-headed Manakin (Pipra erythrocephala, 1 Blue-grey Tanager (Thraupis episcopus, and 1 Emerald Starling (Coccycolius iris. Affected animals displayed nonspecific clinical signs or were found dead. The ventricular nematodes were consistent in morphology with Procyrnea sp. Koilin fragmentation with secondary bacterial and fungal infections was the most frequently observed pathologic lesion. Secondary visceral amyloidosis, attributed to chronic inflammation associated with nematodiasis, was present in 4 individuals. An insect intermediate host is suspected but was not identified. Native passerine species within or around the aviary may be serving as sylvatic hosts.

    2011-11-01

    Full Text Available Abstract Background Effects of polyploidisation on gene flow between natural populations are little known. Central European diploid and tetraploid populations of Arabidopsis arenosa and A. lyrata are here used to study interspecific and interploidal gene flow, using a combination of nuclear and plastid markers. Results Ploidal levels were confirmed by flow cytometry. Network analyses clearly separated diploids according to species. Tetraploids and diploids were highly intermingled within species, and some tetraploids intermingled with the other species, as well. Isolation with migration analyses suggested interspecific introgression from tetraploid A. arenosa to tetraploid A. lyrata and vice versa, and some interploidal gene flow, which was unidirectional from diploid to tetraploid in A. arenosa and bidirectional in A. lyrata. Conclusions Interspecific genetic isolation at diploid level combined with introgression at tetraploid level indicates that polyploidy may buffer against negative consequences of interspecific hybridisation. The role of introgression in polyploid systems may, however, differ between plant species, and even within the small genus Arabidopsis, we find very different evolutionary fates when it comes to introgression.

  20. EDITORIAL The 17th Central European Workshop on Quantum Optics

    2011-02-01

    Although the origin of quantum optics can be traced back to the beginning of the 20th century, when the fundamental ideas about the quantum nature of the interaction between light and matter were put forward, the splendid blossoming of this part of physics began half a century later, after the invention of masers and lasers. It is remarkable that after another half a century the tree of quantum optics is not only very strong and spreading, but all its branches continue to grow, showing new beautiful blossoms and giving very useful fruits. A reflection of this progress has been the origin and development of the series of annual events called the Central European Workshops on Quantum Optics (CEWQO). They started at the beginning of the 1990s as rather small meetings of physicists from a few countries in central-eastern Europe, but in less than two decades they have transformed into important events, gathering 100 to 200 participants from practically all European countries. Moreover, many specialists from other continents like to attend these meetings, since they provide an excellent chance to hear about the latest results and new directions of research. Regarding this, it seems worth mentioning at least some of the most interesting and important areas of quantum optics that have attracted the attention of researchers for the past two decades. One of these areas is quantum information, which over the course of time has become an almost independent area of quantum physics. But it still maintains very close ties with quantum optics. The specific parts of this area are, in particular, quantum computing, quantum communication and quantum cryptography, and the problem of quantitative description of such genuine quantum phenomena as entanglement is one of the central items in the current stream of publications. Theory and experiment related to quantum tomography have also become important to contemporary quantum optics. They are closely related to the subject of so

    Full Text Available It is well known that empirical data coming from financial markets, like stock market indices, commodities, interest rates, traded volumes and foreign exchange rates have a multifractal structure. Multifractals were introduced in the field of economics to surpass the shortcomings of classical models like the fractional Brownian motion or GARCH processes. In this paper we investigate the multifractal behavior of Central and Eastern European foreign exchange rates, namely the Czech koruna, Croatian kuna, Hungarian forint, Polish zlot, Romanian leu and Russian rouble with respect to euro from January 13, 2000 to February 29, 2012. The dynamics of exchange rates is of interest for investors and traders, monetary and fiscal authorities, economic agents or policy makers. The exchange rate movements affect the international balance of payments, trade flows, and allocation of the resources in national and international economy. The empirical results from the multifractal detrending fluctuation analysis algorithm show that the six exchange rate series analysed display significant multifractality. Moreover, generating shuffled and surrogate time series, we analyze the sources of multifractality, long-range correlations and heavy-tailed distributions, and we find that this multifractal behavior can be mainly attributed to the latter. Finally, we propose a foreign exchange market inefficiency ranking by considering the multifractality degree as a measure of inefficiency. The regulators, through policy instruments, aim to improve the informational inefficiency of the markets, to reduce the associated risks and to ensure economic stabilization. Evaluation of the degree of information efficiency of foreign exchange markets, for Central and Eastern Europe countries, is important to assess to what extent these countries are prepared for the transition towards fully monetary integration. The weak form efficiency implies that the past exchange rates cannot help to

    Full Text Available The European bitterling (Rhodeus amarus is a small cyprinid fish whose populations declined markedly between 1950 and 1980. However, its range currently expands, partly due to human-assisted introductions. We determined the genetic variability and detailed spatial structure among bitterling populations in Central Europe and tested alternative hypotheses about colonization of this area. Twelve polymorphic microsatellite loci on a large sample of 688 individuals had been used to analyse genetic variability and population structure. Samples originated from 27 localities with emphasis on area of the Czech Republic where three major sea drainages (Black, Baltic, and Northern Sea meet. Highly variable level of intrapopulation genetic variability had generally been detected and a recent decrease in numbers (“bottleneck” had been indicated by genetic data among six populations. High level of interpopulation differentiation was identified even within the basins. There was a significant role of genetic drift and indications of low dispersal ability of R. amarus. Surprisingly, the Odra River was inhabited by two distinct populations without any genetic signatures of a secondary contact. Czech part of the Odra (Baltic basin was colonized from the Danubian refugium (similarly to adjacent Danubian basin rivers including the Morava, while Polish part of the Odra was genetically similar to the populations in the Vistula River (Baltic basin, that has been colonized by a different (Eastern phylogeographic lineage of R. amarus. Most Czech R. amarus populations were colonized from the Danubian refugium, suggesting potential for a human-mediated colonization of the Odra or Elbe Rivers by R. amarus. One Elbe basin population was genetically mixed from the two (Danubian and Eastern phylogeographic lineages. In general the Czech populations of R. amarus were genetically stable except for a single population which has probably been recently introduced. This research

    Much of our present understanding of the microscopic world is based on quantum mechanics. The field owes much of its existence to the venerable science of optics, since the fundamental ideas on the nature of the interaction between light and matter lie at the roots of its origin. We have now reached one century of quantum mechanics. In contrast, the splendid blossoming of quantum optics began only after the comparatively recent invention of the laser. Since then, it has become an exciting and always expanding area at the cutting-edge of research, in part because theory and experiment are more closely connected in this field than any other. Moreover, the technological distance between fundamental studies and practical applications has always been very short in quantum optics. As a result, modern engineering is increasingly based on quantum rather than classical physics; we are facing a transition similar to the one society confronted 200 years ago, at the start of the Industrial Revolution. In parallel with this, the physics community is witnessing the recent and vigorous emergence of quantum information. It aims at exploring the physical foundations of information and at developing efficient methods for processing quantum information. The questions driving this field reveal a profound change in attitude towards fundamental aspects of quantum theory. The photon turns out to be a tool extremely well suited to exploring theoretical quantum information schemes and their experimental implementations. Mirroring this continued progress has been the growth and development of the series of annual Central European Workshops on Quantum Optics (CEWQO). The series started at the beginning of the 1990s, as rather small meetings of physicists from a few countries in central-eastern Europe. In two decades, the workshops have transformed into important events that reach well beyond the original rather restricted geographical limits. The history of CEWQOs can be found in the preface

    A proposal for organisation of a Network to be known as INTERGEO is presented, which should extend and reinforce the cooperation for the development of the direct application of geothermal energy between the developed EC countries and the ones of the so called Central/East European region. Unter the term `developed countries` for this particular energy source utilisation mainly Italy, France and Germany should be understood. The Central/East European region consists the following countries: Albania, Bosnia and Herzegovina, Bulgaria, Belarus, Croatia, Czech Republic, Estonia, Hungary, Latvia, Lituania, Macedonia, Moldova, Poland, Roumania, Slovenia, Slovakia, Turkey, Ukraine and Yugoslavia. The idea itself, the need and possibilities for organisation, possible plan of action and expected benefits for the EC and Central/East European countries are elaborated in order to come to the conclusions for the proposal justifiableness and feasibility for realisation.

    The possible existence of autochthonous sandfly populations in Central Europe north of the Alps has long been excluded. However, in the past years, sandflies have been documented in Germany, Belgium, and recently, also in Austria, close to the Slovenian border. Moreover, autochthonous human Leishmania and Phlebovirus infections have been reported in Central Europe, particularly in Germany. From 2010 to 2012, sandfly trapping (740 trap nights) was performed at 53 different capture sites in Austria using battery-operated CDC miniature light traps. Sites were chosen on the basis of their climate profile in the federal states Styria, Burgenland, and Lower Austria. Sandfly specimens found were transferred to 70% ethanol for conservation. Identification was based on morphological characters of the male genitalia and the female spermathecae, respectively. Altogether, 24 specimens, 22 females and 2 males, all identified as Phlebotomus (Transphlebotomus) mascittii Grassi, 1908, were found at six different sampling sites in all three federal states investigated. The highest number of catches was made on a farm in Lower Austria. Altogether, the period of sandfly activity in Austria was shown to be much longer than presumed, the earliest capture was made on July 3rd and the latest on August 28th. Sandflies have been autochthonous in Austria in small foci probably for long, but in the course of global warming, further spreading may be expected. Although P. mascittii is only an assumed vector of Leishmania spp.-data on its experimental transmission capacity are still lacking-the wide distribution of sandflies in Austria, a country thought to be free of sandflies, further supports a potential emergence of sandflies in Central Europe. This is of medical relevance, not only with respect to the transmission of Leishmania spp. for which a reservoir is given in dogs, but also with respect to the phleboviruses.

    Full Text Available European Union enlargement and accession are reflexive of both EU and post-communist social policies. There is a unique “dialogue“ going on, indicative of fundamental aspects of post-communist, post-transitional social policy. It is also a 'mirror' that reflects shortcomings of governance, and often presents a neglected institutional landscape. Therefore, the Europeanisation of social policy is an essential transformation process for post-communist countries whereby a new language and new concepts are introduced, the outlines of new social-policy governance emerge and enter the space in which social policy is formulated and considered.

    Full Text Available The empirical record on PPP tests for transition economies is far from being so opulent as it is for the developed market economies. This paper attempts to fill this gap by scrutinizing the theory of PPP on a sample of Central and Eastern European economies. The paper has two main advances with respect to previous PPP studies. First, it employs a monthly data base on real exchange rates for a panel of 12 Central and Eastern European economies by testing the theory separately with respect to US dollar and with respect to Euro. Second, we utilise a panel unit root test that involves the estimation of the ADF regression in a SUR framework. Since our study found support for the validity of PPP in some reforming European economies, special attention should be devoted to individual country-specific factors that cause PPP deviations.

    This review considers potential effects of atmospheric change and climate warming within the timberline ecotone of the Central European Alps. After focusing on the impacts of ozone (O(3)) and rising atmospheric CO(2) concentration, effects of climate warming on the carbon and water balance of timberline trees and forests will be outlined towards conclusions about changes in tree growth and treeline dynamics.Presently, ambient ground-level O(3) concentrations do not exert crucial stress on adult conifers at the timberline of the Central European Alps. In response to elevated atmospheric CO(2)Larix decidua showed growth increase, whereas no such response was found in Pinus uncinata. Overall climate warming appears as the factor responsible for the observed growth stimulation of timberline trees.Increased seedling re-establishment in the Central European Alps however, resulted from invasion into potential habitats rather than upward migration due to climate change, although seedlings will only reach tree size upon successful coupling with the atmosphere and thus loosing the beneficial microclimate of low stature vegetation.In conclusion, future climate extremes are more likely than the gradual temperature increase to control treeline dynamics in the Central European Alps.

    Part of the problem with assessing landslide hazards is to understand the variable settings in which they occur. There is growing consensus that hazard assessments require integrated approaches that take account of the coupled human-environment system. Here we provide a synthesis of societal exposure and vulnerability to landslide hazards, review innovative approaches to hazard identification, and lay a focus on hazard assessment, while presenting the results of historical case studies and a landslide time series for Germany. The findings add to a growing body of literature that recognizes societal exposure and vulnerability as a complex system of hazard interactions that evolves over time as a function of social change and development. We therefore propose to expand hazard assessments by the framework and concepts of systems analysis (e.g., Liu et al., 2007) Results so far have been promising in ways that illustrate the importance of feedbacks, thresholds, surprises, and time lags in the evolution of landslide hazard and risk. In densely populated areas of Central Europe, landslides often occur in urbanized landscapes or on engineered slopes that had been transformed or created intentionally by human activity, sometimes even centuries ago. The example of Germany enables to correlate the causes and effects of recent landslides with the historical transition of urbanization to urban sprawl, ongoing demographic change, and some chronic problems of industrialized countries today, including ageing infrastructures or rising government debts. In large parts of rural Germany, the combination of ageing infrastructures, population loss, and increasing budget deficits starts to erode historical resilience gains, which brings especially small communities to a tipping point in their efforts to risk reduction. While struggling with budget deficits and demographic change, these communities are required to maintain ageing infrastructures that are particularly vulnerable to

    Full Text Available The paper presents the monetary policy analysis of the European Central Bank (ECB under the present crisis conditions. The paper systematizes the ECB monetary policy in today's crisis and researches it at different stages of the crisis. A detailed analysis showed that the ECB's monetary policy is significantly different from the actions of other central banks during the current crisis (for example, the Federal Reserve. Thus, the ECB unconventional monetary policy combined with traditional measures, but does not replace them. Often ECB use credit easing instead of quantitative easing. The ECB's monetary policy used not only to combat the financial crisis, such as the Fed, but also to deal with the debt crisis. These features of the ECB’s monetary policy were due to both the institutional characteristics of the European Union, as well as special conditions of flow of the financial crisis in the euro zone.

    Full Text Available The paper aims to empirically assess, using panel data estimation techniques, the effects of public indebtedness on economic growth for a group of 11 Central and Eastern European countries and over the period 1994-2013. Our hypothesis is that, although public indebtedness may fuel economic growth, once public debt breaches a certain threshold the effects are reversed and public indebtedness negatively affects GDP growth rates. The results of our study confirm this kind of relationship, with a maximum debt threshold for all countries of about 45-55% of GDP, lower for the less developed (like Romania and Bulgaria and higher for the more developed ones. Also, the threshold for Central and Eastern European countries is found to be lower than the one identified in other empirical studies for developed EU countries, as the former enjoy lower credibility, higher vulnerability to shocks and depend more on external capital transfers.

  5. Regional Strategies Concerning Nuclear Fuel Cycle and HLRW in Central and Eastern European Countries

    International Nuclear Information System (INIS)

    In March 2009 a regional meeting on national strategies concerning nuclear fuel cycle and high level radioactive waste (HLRW) was held in Budapest with the participation of Central and Eastern European countries, Russia and France. Following the meeting a Task Force was set-up with fuel cycle experts from different countries in order to analyse the possible fuel cycle strategies in the region. The Task Force produced an Opinion Paper in spring 2010 on the Regional Strategies Concerning Nuclear Fuel Cycle and HLRW in Central and Eastern European Countries with several recommendations. The Opinion Paper emphasizes that the countries in the Central and Eastern European region are small, and they have modest NPP capacities compared to large nuclear countries. Spent fuel reprocessing facilities are not available in the region, but Russia and France offer such services for these countries. Deep geological repositories are not in operation in any of these countries, and in some of the countries the geological conditions do not allow to design such facilities. For these reasons the countries of the region may need special services and a regional approach could produce common benefit for waste management. (author)

    Fire is an important earth surface process that interacts with climate and vegetation and influences global biogeochemical cycles and carbon budget. Moreover, fire is tightly connected to the evolution and distributions of human beings. Especially in the humid vegetation zones that naturally do not inflame easily, fire has been the major tool to convert forests to arable land. In the central European lowlands, naturally dominated by broad-leaved forests, palaeofires were strongly related to human impact during at least the last 6000 years. Hence, the detection of past biomass burning in the sedimentological record points to human activity. Charcoal (black carbon) is the classical and widely-used proxy to reconstruct past fire histories. Abundant sedimentary charcoal records exist around the globe, and many are included in the Global Charcoal Database (GCD, www.gpwg.org). Molecular fire markers, on the other hand, are now being developed as new proxies to detect past biomass burning. This study reviews classical and "new" fire-proxies in peat and lake sediments that allow to reconstruct the signals of human impact on a regional scale in the central European lowlands with high temporal resolution. Furthermore, the charcoal records from the GCD and other sources covering the central European lowlands and adjacent areas were integrated in a spatial synthesis to document the current state-of-knowledge on regional Holocene fire history. We show preliminary charcoal data from the annually-laminated sediments of lakes Tiefer See (northeastern Germany) and Czechowskie (northern Poland). Links to reconstructed local and European-wide vegetation successions will be provided, as in times with dry climate and the dominance of a certain fire-prone vegetation cover (e.g., Pinus spec.), wildfires might have played a further important role. However, the interpretation of charcoal records is not always straightforward. Hence, we also discuss the potentials of other palaeofire

  7. Economic potential of demand response at household level—Are Central-European market conditions sufficient?

    International Nuclear Information System (INIS)

    The aim of this paper is to show the economic potential of demand response (DR) on household level at Central European market conditions. Thereby, required economic benefits for consumers' participation, the realistic load shifting potential at household level and the estimation of essential intelligent infrastructure costs are discussed. The core of this paper builds a case-study applying spot market-oriented load shifting from the supplier's point of view by using Austrian electricity market data, household load profiles as well as a heat pump and e-car charging load profile. It is demonstrated which cost savings for suppliers can be derived from such load shifting procedure at household level. Furthermore, upper cost limits for intelligent infrastructure in order to break-even are derived. Results suggest to take a critical look at European discussions on DR implementation on household level, showing that at Central European market conditions the potential for DR at household level is restricted to significant loads and hence, the applied load shifting strategy is only beneficial with application to heat pumps. In contrast, the frequently discussed shifting of conventional household devices' loads (such as washing machines) economically does not add up. - Highlights: • Calculation of economic potential of domestic DR at Central European market conditions. • Model and case-study of spot market-oriented load shifting from supplier's perspective. • Derivation of supplier's cost savings and upper cost limits for ICT infrastructure. • Results show economic potential of domestic DR to be restricted to significant loads. • Shifting of washing machines economically does not pay off in contrast to heat pumps

    Various studies on ancient DNA have attempted to reconstruct population movement in Asia, with much interest focused on determining the arrival of European lineages in ancient East Asia. Here, we discuss our analysis of the mitochondrial DNA of human remains excavated from the Yu Hong tomb in Taiyuan, China, dated 1400 years ago. The burial style of this tomb is characteristic of Central Asia at that time. Our analysis shows that Yu Hong belonged to the haplogroup U5, one of the oldest western Eurasian-specific haplogroups, while his wife can be classified as haplogroup G, the type prevalent in East Asia. Our findings show that this man with European lineage arrived in Taiyuan approximately 1400 years ago, and most probably married a local woman. Haplogroup U5 was the first west Eurasian-specific lineage to be found in the central part of ancient China, and Taiyuan may be the easternmost location of the discovered remains of European lineage in ancient China.

    Full Text Available This article evaluates the level of integration of Members of the European Parliament from Central and Eastern Europe in the European Parliament after the EU enlargements of 2004 and 2007. The main objective is to address the puzzle of how the European Parliament’s political groups could maintain or even increase their voting cohesion after the influx of a significantly large number of new MEPs coming from countries with different historical experience, socio-economic characteristics, and political and party systems. Three indicators of MEP integration are defined: integration into parliamentary leadership, integration into parliamentary work, and integration into voting patterns. The article uses data from the VoteWatch.eu website on MEPs’ activities and voting between the years 2004-2011, as well as data from official documents of the European Parliament and its political groups. Analysis of the data reveals that the new member states’ MEPs were significantly under-represented in parliamentary leadership and key legislative activities, despite the fact that their voting loyalty to their political groups was greater than that of their colleagues from older member states.

    Full Text Available In this paper an analysis on dollar/euro exchange rate, oil price and European Central Bank monetary policy is worked out. Firstly, data on the main variables related with the exchange rate and an equation to explain the variation of the exchange rate in the period March 1998-September 2000 are presented; secondly, the consequences of oil price growth and eurodevaluation on the US and European economies are taken into account; lastly, different policy strategies to stop eurodevaluation are discussed. The European Central Bank strategy, that consists of small increases of the interest rate, is not reaching any result. An alternative strategy is based on innovative public demand, that should be financed by European bonds using "central bank excess funds" as security. Public demand of infrastructures and new technologies should aim at reducing oil dependence and would stimulate growth and sustainable development in Europe, with positive effects on the exchange rate.

    Full Text Available Without a lender of last resort financial stability is not possible and systemic financial crises get out of control. During and after the Great Recession the US Federal Reserve System (Fed and the European Central Bank (ECB took on the role of lender of last resort in a comprehensive way. The Fed stabilised the financial system, including the shadow banking system. However, the chance to fundamentally restructure the financial system was not used. The ECB was confronted with sovereign debt crises and an incomplete integration of the European Monetary Union (EMU. It followed a kind of “muddling through” to keep the Euro area together. In the EMU not only a fundamental restructuring of the financial system is needed but also a deeper economic and political integration. The Fed and the ECB both were the most important institutions to avoid repetition of the 1930s.

    Bread-making quality traits are central targets for wheat breeding. The objectives of our study were to (1) examine the presence of major effect QTLs for quality traits in a Central European elite wheat population, (2) explore the optimal strategy for predicting the hybrid performance for wheat quality traits, and (3) investigate the effects of marker density and the composition and size of the training population on the accuracy of prediction of hybrid performance. In total 135 inbred lines of Central European bread wheat (Triticum aestivum L.) and 1,604 hybrids derived from them were evaluated for seven quality traits in up to six environments. The 135 parental lines were genotyped using a 90k single-nucleotide polymorphism array. Genome-wide association mapping initially suggested presence of several quantitative trait loci (QTLs), but cross-validation rather indicated the absence of major effect QTLs for all quality traits except of 1000-kernel weight. Genomic selection substantially outperformed marker-assisted selection in predicting hybrid performance. A resampling study revealed that increasing the effective population size in the estimation set of hybrids is relevant to boost the accuracy of prediction for an unrelated test population.

    This article explores the Central European philosophical roots of perceptual psychology from a historical perspective. It will be shown that Alexius Meinong's notion of a forum of perception is the point of departure for a beginning inclusion of external factors in explaining perception. This conclusion is mainly because of Fritz Heider's early contributions on perception and its influence on Egon Brunswik. In addition, the impact of Meinong and Edmund Husserl-both students of Franz Brentano-on Brunswik's teacher, Karl Bühler, is highlighted.

Its main purpose is to determine how far the CEE countries have progressed along their IDPs since the beginning of transition. The results show that half of the analyzed countries have already reached Stage 3 of the IDP, while the other half are either firmly in Stage2 or are approaching Stage 3. With some notable exceptions, the study points to conformity of the analyzed IDP trajectories with Dunningĺs model.

  20. Perspectives for long-term competition in the central European electricity market

    International Nuclear Information System (INIS)

    In this paper we focus on the Central European electricity market and analyse whether liberalization, deregulation, and privatization are sufficient to bring about real competition. Moreover, we discuss the relevance of the following conditions to bring about real competition and to avoid market power: 1) A rigorous correct un bundling; 2) excess capacities in transmission; 3) excess capacities in generation; 4) a large number of generators and suppliers; 5) the balanced existence of short-term (e.g. spot markets) and long-term markets (e.g. bilateral contracts, forwards); 6) full liberalization; Some major findings of this analysis are: 1) Currently, demand is continuously increasing while capacities are shut down. At least in 2009 demand will have caught up with generation capacities. This could lead to severe price spikes. 2) The Central European electricity market is separated from other markets by means of limited transmission capacities; 3) With respect to effective competition in Central Europe the major problems are: i) a very small (and continuously decreasing) number of generators, and ii) a lack of serious un bundling between generation and transmission mainly in Germany; This leads to cross-subsidization of generation by the network operation and to a heavy discrimination of other and new generators; 4) Moreover, a crucial condition for active competition is a sufficiently large transmission grid. Yet, currently especially at the border to the new EU member countries transmission capacities are rather scarce and there are no signs of extensions of the grid. This also limits the access of countries with potential excess capacities like Ukraine, Bulgaria, Romania to the Central European market The major conclusion of this analysis is: All conditions investigated above must be fulfilled simultaneously to bring about a competitive electricity market in Western Europe and the extended European Union. If only one of these conditions is missing, competition

    The Russia-Ukraine “gas wars” and the cold winter that hit Southern and Central Europe in January 2006 and 2009 highlighted Europe’s commodity insecurity and its dependence on Russian good will. In all fairness, it should be noted that some studies on this topic appeared even before the “cold winter” of 2009, but their impact on the leadership of the European Commission was insignificant, to put it mildly. This is evident from the fact that prior to the 2009 crisis the International Energy Ag...

    Full Text Available This paper examines the impact of corruption on foreign direct investment inflows for ten Central and Eastern European states. The paper attempts to answer the question: what is the role of corruption in attracting foreign direct investments? Using the data from UNCTAD for foreign direct investment and Corruption Perception Index from Transparency International, for a period of 12 years, 2000-2012, we evaluate the specific impact of corruptions on FDI using GDP as control variable. Our results confirm the majority of literature and show a negative significant relation between the variables analyzed, but at a lower intensity than expected.

    Full Text Available Situation of lichens of aquatic and transient habitats in Eastern and East-Central European lowlands is discussed basing on example of several selected species: Leptogium biatorinum, Sarcosagium campestre, Steinia geophana, Verrucaria aquatilis, V. hydrela, V. praetermissa, V. xyloxena. Both habitat types are generally very much neglected in the region and all species show large spatial gaps in recording, which makes it difficult to judge both about their true distribution limits and spreading dynamics. On the other hand, targeted search through the suitable habitats and abundance of such indicate that many of these lichens are probably not uncommon in the region.

  4. The Image of the East-Central European in Rose Tremain’s The Road Home

    2015-12-01

    Full Text Available In Rose Tremain’s The Road Home, the culture clash of the British and the East-Central European is portrayed through a complex symbolism centred on images of food, consumption and waste. This literary representation may shed light on British literary auto-images, as well as hetero-images of the Eastern European immigrant. The novel’s presentation of this culture shock is defined by the cultural historical and economic circumstances of the parties. Food and material provide the symbolic sphere where the relationship between Britain and East-Central Europe is characterized in terms of capitalist worldview as opposed to a post-communist existence. William Shakespeare’s Hamlet is the most important intertext for Tremain’s novel. Hamlet is obsessed with the vulnerability of material in light of the spiritual value attached to it in the form of human soul. Stephen Greenblatt’s ideas on food, waste and the Christian belief in divine existence residing in material objects - ideas that originate in early modern times - shed light on the motif of material and food in The Road Home. Seen through the symbolism of food and the idea of differing values being attached to matter, the narrative identity of Lev, the protagonist of Tremain’s work, experiences drastic change due to his encounter with the capitalist, British ‘other’.

    2011-12-01

    Full Text Available Originally published in Centropa: Journal of Central European Art and Architecture 5, n. 1 (January 2005: 16-25. Kimberly A. Smith discusses the ways in which the understanding of style was articulated by intellectuals working in the late nineteenth century, primarily in Germany and Austria, and the epistemological repercussions of this shift in thinking for both the theory and practice of central European art in the years before World War I. Smith focuses in particular on the writings of Alois Riegl, in which this approach to thinking about style came to its most influential fruition, and proposes that Riegl’s conception of form had implications for artistic practice. Riegl’s methodological understanding of artistic form drew connections between morphological types and perceptions of reality, thereby altering the ways in which artists could conceive of aesthetic authenticity. Style itself could be seen as the harbinger of truth, opening up the possibility that any style might offer a genuine revelation of the real. Yet as Smith shows, the Rieglian theory of meaningful form may have encouraged an artistic pluralism that subverted the very Kunstwollen theory of historically unified style from which it sprung.

  6. Financial development and energy consumption in Central and Eastern European frontier economies

    International Nuclear Information System (INIS)

    This study examines the impact of financial development on energy consumption in a sample of 9 Central and Eastern European frontier economies. Several different measures of financial development are examined including bank related variables and stock market variables. The empirical results, obtained from dynamic panel demand models, show a positive and statistically significant relationship between financial development and energy consumption when financial development is measured using banking variables like deposit money bank assets to GDP, financial system deposits to GDP, or liquid liabilities to GDP. Of the three stock market variables investigated, only one, stock market turnover, has a positive and statistically significant impact on energy consumption. Both short-run and long-run elasticities are presented. The implications of these results for energy policy are discussed. - Research Highlights: → Financial development affects energy consumption in 9 Central and Eastern European frontier economies. → Bank variables have a larger impact on energy consumption than do stock market variables. → Long run bank elasticities range from 0.117 to 0.276. → These results have implications for energy demand forecasts and greenhouse gas emissions.

    Full Text Available In this study, we examine the pattern of occurrence of Impatiens parviflora in Central European oak forests over time and its ecological requirements within these types of communities. Research was based on phytosociological data collected in 3776 relevés. A modified TWINSPAN algorithm were used to distinguish the groups of oak forests. The ecological preferences of the I. parviflora and studied communities as well as differences between invaded and non-invaded vegetation plots were analyzed using mean weighted Ellenberg indicator values (EIVs. Finally, both the temporal pattern of I. parviflora participation and changes in its coverage in the studied communities were analyzed. Our study confirmed a high adaptability of this species with respect to temperature, moisture, soil reaction and nutrients and determined its broad ecological optimum in oak forests. However, it also revealed both a greater sensitivity of some communities within Central European oak forests to the invasion of I. parviflora and differences in habitat conditions between invaded and non-invaded vegetation plots. This suggests that the habitat niche of I. parviflora within oak forests is not accidental. The analysis of temporal changes in the frequency of I. parviflora confirmed a 20% increase in relevés over the last 50 years. However, we did not identify any statistically significant rise in the coverage of I. parviflora in oak forests specifically during the studied period.

The present study analyzed triathletes participating in Double Iron ultratriathlons to determine the origin of the fastest Double Iron ultratriathletes, focusing on European countries.Methods: Participation and performance trends of finishers in Double Iron ultratriathlons from 1985–2011 of the different countries were investigated. Additionally, the performance trends of the top three women and men overall from 2001–2011 were analyzed.Results: A total of 1490 finishers originated from 24 different European countries and the United States. The number of European triathletes increased for both women (r2 = 0.56; P < 0.01 and men (r2 = 0.63; P < 0.01. The number of the North American triathletes increased for women (r2 = 0.25; P < 0.01, but not for men (r2 = 0.02; P > 0.05. Hungarian triathletes showed a significant improvement in both overall race times and in cycling split times, Swiss triathletes improved both their swim and run times, and French triathletes improved their swim times.Conclusion: Men and women triathletes from Central European countries such as France, Germany, Switzerland, and Hungary improved Double Iron ultratriathlon overall race times and split times during the 26-year period. The reasons might be the social and economic factors required to be able to participate in such an expensive and lavish race. Also, a favorable climate may provide the ideal conditions for successful training. Future studies need to investigate the motivational aspects of European

  9. Options of biofuel trade from Central and Eastern to Western European countries

    International Nuclear Information System (INIS)

    Central and Eastern European countries (CEEC) have a substantial biomass production and export potential. The objective of this study is to assess whether the market for biofuels and trade can be profitable enough to realize a supply of biofuels from the CEEC to the European market and to estimate the cost performance of the energy carriers delivered. Five NUTS-2 (Nomenclature d'Unites Territoriales Statistiques) regions with high biomass production potentials in Poland, Romania, Hungary and the Czech Republic were analysed for biofuel export options. From these regions pellets from willow can be provided to destination areas in Western European countries (WEC) at costs of 105.2-219.8 EUR t-1. Ethanol can be provided at 11.95-20.89 EUR per GJ if the biomass conversion is performed at the destination areas in the WEC or at 14.84-17.83 EUR GJ-1J if the biomass to ethanol conversion takes place (at small scale) at the CEEC region where the biomass is produced. Short sea shipping shows most cost advantages for longer distance international transport compared to inland waterway shipping and railway. Another reason for lower biofuel supply costs are shorter distances between the regions of biomass production and the destination areas. Therefore the Szczecin region in Poland, closely located to the Baltic Sea, shows a better economic performance for long distance trade of biomass production than the selected region in Hungary ('land-locked'). It is concluded that in future key CEEC regions can supply (pre-treated) biomass and biofuels to the European market at cost levels, which are sound and attractive to current and expected diesel and gasoline prices.

    Full Text Available Holocene climate was characterised by variability on multi-centennial to multi-decadal time scales. In central Europe, these fluctuations were most pronounced during winter. Here we present a new record of past winter climate variability for the last 10.8 ka based on four speleothems from Bunker Cave, Western Germany. Due to its central European location, the cave site is particularly well suited to record changes in precipitation and temperature in response to changes in the North Atlantic realm. We present high resolution records of δ18O, δ13C values and Mg/Ca ratios. We attribute changes in the Mg/Ca ratio to variations in the meteoric precipitation. The stable C isotope composition of the speleothems most likely reflects changes in vegetation and precipitation and variations in the δ18O signal are interpreted as variations in meteoric precipitation and temperature. We found cold and dry periods between 9 and 7 ka, 6.5 and 5.5 ka, 4 and 3 ka as well as between 0.7 to 0.2 ka. The proxy signals in our stalagmites compare well with other isotope records and, thus, seem representative for central European Holocene climate variability. The prominent 8.2 ka event and the Little Ice Age cold events are both recorded in the Bunker cave record. However, these events show a contrasting relationship between climate and δ18O, which is explained by different causes underlying the two climate anomalies. Whereas the Little Ice Age is attributed to a pronounced negative phase of the North Atlantic Oscillation, the 8.2 ka event was triggered by cooler conditions in the North Atlantic due to a slowdown of the Thermohaline Circulation.

    Full Text Available This paper analyzes the relationship between economic performance and institutional development in several Central and Eastern European Countries. Our meta-argument is that the structural transformations at the levels of the quantitative variables and mechanisms are only a part of the transition processes. In order to view the big picture, the qualitative aspects related to public policies and institutions should also be considered. We test the linkages between the quality of public policies and institutions for seven Central and Eastern European countries (Bulgaria, Poland, Czech Republic, Hungary, Slovenia, Slovakia and Romania for a time span between 2001 and 2011. These countries are displaying a certain degree of heterogeneity in terms of economic performances and the design and implementation of public policies. We use for our analysis the World Bank indicators from World Wide Governance Indicators. In order to deal with the potential reverse causality issues, we employ Generalized Method of Moments Framework (GMM by using the lagged variables as instruments. The impact of governance indicators is statistically significant even if we use several control variables: exchange rate, unemployment, current account deficit, taxes burden and price stability. The corresponding Sargan and Arellano-Bond test for zero autocorrelation in first-differenced errors tests shows that the results display a corresponding robustness. The main policy implications for our findings may be synthesized by the thesis, according to which a proper design of public policies, a high degree of their effectiveness and accountability, a stable social and political environment together with the rule of law and efficient anticorruption mechanisms are critical determinants of economic growth even in emerging markets.

    Full Text Available Before exploring the selectivity of educational attainment in detail, this article extensively describes the contours of educational systems in Central and Eastern European (CEE countries. These countries provide an interesting setting in view of their post-secondary education expansion and differentiation, as well as their variation in the degree of vocational orientation at the secondary level. Drawing on high quality, national micro data, we find that students from disadvantaged family backgrounds who manage to enter post-secondary education are ʽdivertedʼ to second-tier post-secondary institutions, while long-term university programs are more likely to be dominated by students whose parents have an academic background. At the secondary level, we confirm the patterns of negative selection among students from lower social backgrounds into lower vocational programs. This diversion effect at the secondary level is especially pronounced in CEE countries that inherited a strong secondary vocational system and reinstalled early tracking.

Among these benefits an important one is represented by the opportunities of Chinese investments in infrastructure, since the EU is suffering from a credit restraint. Also, The Silk Road Economic Belt could lead to a potential increase in the bilateral trade. Analyzing the literature in the field and the various official information available online, this paper aims to depict the Chinese project form the Eastern European perspective, identifying local priorities, conflicting interests, possible infrastructure projects, routes, focusing on two strategic countries in the region: Romania and Serbia, both displaying advantages and disadvantages.

    Full Text Available Despite the growing interest in foreign direct investments (FDI, substantial uncertainty still exists regarding what stimulates foreign investors to operate in a foreign market and uneven distribution of FDI across countries. Using panel data for 2001 -2012 period, the major determinants of the FDI inflows into the Central and Eastern European Countries are analysed in this study. Strong evidence are found that while EU CR indices, EU and USA real GDP growth rates and global financial crisis have power to explain FDI inflows among all other push factors, labour cost, electricity price, real exchange rate and host CR indices have strong influential on FDI as the most effective pull factors. However, study fails to find any effect of openness, tax rates on commercial profits, USA CR indices, interest rate differentials and host real GDP growth on FDI.

    Full Text Available This paper aims to investigate stochastic properties of the consumption-income ratios in eleven central and eastern European (CEE countries: Bulgaria, Croatia, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia, and Slovenia. The heterogeneous panel unit root tests are used to account for cross-sectional dependence and the Modified Augmented Dickey-Fuller unit root test over the period March 1997-September 2012. The half-lives are also calculated as to find the strong mean-reversion in the consumption income ratio for nine of eleven CEE economies; and the exceptions are Croatia and Slovenia. In other words, empirical findings provide significant support for the existence of hypothesis that the consumption-income ratio is a mean reversion. Accordingly, the policy implications have permanent effects on the consumption of households only in Croatia and Slovenia.

    Full Text Available The establishment of democracy in the communist countries, which generated profound social and economic transformation, was accompanied by a decline in fertility. We attempt to provide an overall survey on fertility since 1989 in ten Central and Eastern European Countries, members of the European Union, and to identify the variables which explain the fertility decline. We will use univariate and multivariate statistical analysis to identify disparities between the ten countries, and the variables which explain these differences. Also, we developed a panel econometric model to confirm the hypothesis of a similar pattern of evolution for fertility in these countries and that the decline in fertility can be explained both through demographic and economic variables. The decline in fertility can be explained by economic growth, marriage, divorce, abortion, and migration. The empirical evidence presented in this paper supports the view that the decline in fertility over the 1989s represents the continuation of a longstanding trend of the previous period, according to the demographic transition theory, but its speed and magnitude has been influenced by the new social and economic landscape. These results can be useful for public authorities of the CEE countries to rethinking demographic policies and to ensure the sustainability of demographic growth.

  2. High-Speed Rail for Central and Eastern European Countries: A Conference Report

    Full Text Available The European transport strategy promotes the role of railways and expects that the key role in passenger transport should be played by high-speed rail (HSR. Although the core network of high-speed lines has already been built and is operating in Western Europe, there has been little coverage so far in Central and Eastern Europe (CEE. The aim of the conference “High-Speed Rail for CEE Countries” that took place in Prague in June 2016 was to put together academics, policy-makers, and practitioners interested in HSR and to formulate recommendations for CEE countries based on West European countries’ experience. Based on the conference presentations and subsequent discussion, the following conclusions were formulated. Firstly, there are many crucial differences in national HSR build-up and operation, which means that former experience of Western Europe is not directly applicable to CEE countries. Secondly, in comparing presentations discussing experiences in France, Britain, Italy, and Germany, it was concluded that the German approach-upgrading existing lines where possible and only building new lines for bottleneck sections-was the most likely appropriate solution in CEE. Lastly, CEE has the additional problem of many border crossings, with a reduction of traffic in comparison with purely domestic routes, and this effect has to be taken into account.

    Full Text Available This paper carries out a growth accounting exercise for the 10 Central and Eastern European (CEE countries that are part of the European Union over the period 1993-2008. We estimate the capital share (α from a Cobb-Douglas production function in an intensive form, by employing panel data techniques. The Hausman and Chi-Square tests indicate that a Cross- Section Random Effects with Period Fixed Effects model best suits our data. Based on this model, we find a capital share between 0.45 and 0.83, higher than the usual 0.3-0.4 used in growth accounting literature. When we take into consideration the quality of labour force the estimated capital share slightly decreases, but still remains high, in a range between 0.39 and 0.79. Our growth accounting results reveal that, on average, capital per worker accumulation is the main engine of growth in CEE, followed by the contribution of total factor productivity (TFP. However, when dividing by sub-periods, we found that the contribution of TFP cannot be neglected since during 1997-2004 it proved to be the main engine of growth in some CEE countries (Czech Republic, Slovakia, Hungary, Lithuania and Romania. Some policy implications are offered based on our results.

    Full Text Available Protected areas are a central pillar of efforts to safeguard biodiversity and ecosystem services, but their contribution to the conservation and management of European cultural landscapes that have complex spatial-temporal dynamics is unclear. The conservation strategy of biosphere reserves aims at integrating biodiversity and ecosystem service conservation with economic development by designating zones of differing protection and use intensities. It is applied worldwide to protect and manage valuable cultural landscapes. Using the example of a German biosphere reserve, we developed a framework to assess the effectiveness of Central European reserves in meeting their land cover related management goals. Based on digital biotope maps, we defined and assessed land cover change processes that were relevant to the reserve management's goals over a period of 13 years. We then compared these changes in the reserve's core, buffer, and transition zones and in a surrounding reference area by means of a geographical information system. (Un-desirable key processes related to management aims were defined and compared for the various zones. We found that - despite an overall land cover persistence of approximately 85% across all zones - differences in land cover changes can be more prominent across zones inside the reserve than between the areas inside and outside of it. The reserve as a whole performed better than the surrounding reference area when using land cover related management goals as a benchmark. However, some highly desirable targets, such as the conversion of coniferous plantations into seminatural forests or the gain of valuable biotope types, affected larger areas in the nonprotected reference area than in the transition zone.

    Full Text Available Pinus pinea is characterized by phenotypic plasticity, tolerance to harsh soils and climates, but low differentiation in growth parameters and low genetic variability. Growth and cone production of six European stone pine provenances (two from Italy, three from Spain and one from Slovenia were analyzed in a field trial experiment established in central Chile. The study evaluated height, diameter at breast height (DBH and crown diameter growth of 147 nineteen-year-old trees per provenance, as well as fruiting variables (i.e., number of cones per tree and cone weight. Survival over the first 7 years was also evaluated. Provenances significantly differed in cone number per tree, cone weight, height and DBH growth, and crown diameter growth. Provenances were grouped according to growth and production variables: one group included the Italian and Slovenian provenances, the second group Andalucía and Sierra Morena (Spain, and the third included Meseta Castellana (Spain. Individual cone production was positively correlated with cone weight and other growth variables. Meseta Castellana provenance showed the highest growth and productivity. Our results provide useful information for the selection of P. pinea provenances to be used in new plantations in central Chile.

    Full Text Available Towards the late 90’s, together with overcoming the shock of transition, most countries in Central and Eastern Europe began a process of profound reform of the pension systems. The aim of these reforms was mainly ensuring the financial sustainability of the pension systems often without taking into account their primary goal: to provide adequate retirement incomes, to allow the elderly to maintain a decent living standard after retirement and to have economic independence. However, a successful pension system is not the one that involves little spending but the one achieving its primary goal while limiting the future pressures on public finances.The economic crisis has increased the vulnerability of the pension systems. The economic recessions or slow economic growth, budget deficits and debt burdens, low employment rates have led to rising the concern about the ability of pension systems to fulfill their purpose. In this context, most Central and Eastern European countries have recently been forced to take up new changes in pensions. In our study we accomplished a comparative analysis of the pension systems’ performance based on calculating a composite indicator that includesthree components: the indicator of adequacy, the financial sustainability indicator and the indicator of modernity. Each of these components is obtained by aggregating a selection of sub-indicators. The purpose of this analysis is to identify best practices for successful reform, but also to highlight potentialhazards or imbalances that might face various emerging countries.

  11. The Implementation of Performance Management in European Central Governments: More a North-South than an East-West Divide

    Directory of Open Access Journals (Sweden)

    Hammerschmid Gerhard

    2015-12-01

    Full Text Available This article presents the first country-comparative evidence on the importance and use of performance management in European central governments, based on an executive survey conducted in 17 countries. The data confirm that performance management has made its way into European central governments and continues to constitute a major reform trend. At the organizational level of ministries and agencies we find a consistently strong use of strategic planning, performance appraisal and management objectives, along with only a partial institutionalization of a performance-management logic. Scepticism towards measurement and the difficulty of acting upon performance information are persistent challenges. We also find that performance-management implementation is significantly stronger in agencies and larger organizations, and that it varies strongly between different countries. Implementation is substantially higher in Scandinavian countries and Anglo-Saxon countries than in Continental and Southern European countries, with a rather varied pattern for Central and Eastern European countries. The findings thereby confirm the need for a more context-sensitive understanding of performance management, along with the need for more extensive research and evidence to further develop this cross-comparative European perspective.

    Full Text Available In this paper an analysis on dollar/euro exchange rate, oil price and European Central Bank monetary policy is worked out. Firstly, data on the main variables related with the exchange rate and an equation to explain the variation of the exchange rate in the period March 1998-September 2000 are presented; secondly, the consequences of oil price growth and eurodevaluation on the US and European economies are taken into account; lastly, different policy strategies to stop eurodevaluation are discussed. The European Central Bank strategy, that consists of small increases of the interest rate, is not reaching any result. An alternative strategy is based on innovative public demand, that should be financed by European bonds using "central bank excess funds" as security. Public demand of infrastructures and new technologies should aim at reducing oil dependence and would stimulate growth and sustainable development in Europe, with positive effects on the exchange rate.       JEL Codes: E58, F31Keywords: Devaluation, Exchange Rates, Monetary

    2015-10-01

    Full Text Available This paper argues that the loose monetary policy of two of the world’s most important financial institutions—the U.S. Federal Reserve Board and the European Central Bank—were ultimately responsible for the outburst of global financial crisis of 2008-09. Unusually low interest rates in 2001- 05 compelled investors to engage in high risk endeavors. It also encouraged some governments to finance excessive domestic consumption with foreign loans. Emerging financial bubbles burst first in mortgage markets in the U.S. and subsequently spread to other countries. The paper also reviews other causes of the crisis as discussed in literature. Some of them relate directly to weaknesses inherent in the institutional design of the European Monetary Union (EMU while others are unique to members of the EMU. It is rather striking that recommended remedies tend not to take into account the policies of the European Central Bank.

  14. Combined dendro-documentary evidence of Central European hydroclimatic springtime extremes over the last millennium

    A predicted rise in anthropogenic greenhouse gas emissions and associated effects on the Earth's climate system likely imply more frequent and severe weather extremes with alternations in hydroclimatic parameters expected to be most critical for ecosystem functioning, agricultural yield, and human health. Evaluating the return period and amplitude of modern climatic extremes in light of pre-industrial natural changes is, however, limited by generally too short instrumental meteorological observations. Here we introduce and analyze 11,873 annually resolved and absolutely dated ring width measurement series from living and historical fir ( Abies alba Mill.) trees sampled across France, Switzerland, Germany, and the Czech Republic, which continuously span the AD 962-2007 period. Even though a dominant climatic driver of European fir growth was not found, ring width extremes were evidently triggered by anomalous variations in Central European April-June precipitation. Wet conditions were associated with dynamic low-pressure cells, whereas continental-scale droughts coincided with persistent high-pressure between 35 and 55°N. Documentary evidence independently confirms many of the dendro signals over the past millennium, and further provides insight on causes and consequences of ambient weather conditions related to the reconstructed extremes. A fairly uniform distribution of hydroclimatic extremes throughout the Medieval Climate Anomaly, Little Ice Age and Recent Global Warming may question the common believe that frequency and severity of such events closely relates to climate mean stages. This joint dendro-documentary approach not only allows extreme climate conditions of the industrial era to be placed against the backdrop of natural variations, but also probably helps to constrain climate model simulations over exceptional long timescales.

  15. National radioactive waste management agencies potential models for Central and Eastern European countries, Cassiopee management

    International Nuclear Information System (INIS)

    In discussing institutional arrangements for radioactive waste disposal organizations particular attentions paid to the relationships between - and the responsibilities of the State, the Regulator, Waste Producer, and the national Waste Management Organization. The IAEA provide guidance relating to the establishment of appropriate radioactive waste management structures. The model of the IAEA guidance on radioactive waste management infrastructure is sometimes referred to as the 'classical triangle' principle. The model separates the three roles of the Regulator, the Waste Producer and the Waste Disposer. Each has separate responsibilities and must exhibit independence from the other. However the triangle also has another dimension, in that the arrangements should be underpinned by from government policy on radioactive waste, on the basis of the guidance on responsibilities set out by the IAEA. Models of the institutional arrangements in the countries of the European Union (EU) typically follow the principles set out by the above. Since the break up of Soviet Union, economic and political changes in the Newly Independent States and the countries of Central and Eastern Europe have, in turn, inspired changes in the management of nuclear power related activities including radioactive waste management, bringing them more in line with practices adopted in the UE. In 1993 the European Commission encouraged the creation of Cassiopee, a Consortium of EU national radioactive waste agencies comprising ANDRA (France), COVRA (The Netherlands), DBE (Germany), ENRESA (Spain), Nirex (UK), ONDRAF/ NIREX (Belgium). The consortium combines the individual members competence and capabilities and provides assistance and advice through the EU programmes to beneficiary countries in two main ways: Developing national radioactive waste management strategies; Advising on the implementation of projects. As such Cassiopee has undertaken two projects of direct relevance to the Bulgarian

The curriculum aims at raising doctors who are excellently prepared for clinical work over as short a time as 5 years; it provides a comprehensive, yet shorter than usual, education that strongly pronounces the importance of increasing the students’ practical clinical competences and rigorously excludes superfluous contents. The curriculum encompasses 52 modules, 32 at the bachelor’s and 20 at the master’s level. Already at the level of the bachelor degree, full employability is given; the students finish the master’s course as medical doctors optimally prepared to manage patients at the level of postgraduate medical education. The structure of the curriculum is modular; each modular component is essential for medical education and contains an average of five European Credit Transfer System credits, amounting to 150 hours of education. Depending on the subspecialty, the courses include lectures, seminars, practical laboratory training, and clinical training at varying quantities. In addition to attendance times, sufficient time slots are prepared for self-study in lectures, seminars, and practical work. With our curriculum, we provide an easily applicable backbone for a modern course of medicine that can be installed also at smaller academic institutions. Keywords: Bologna

    The deep resistivity structure was estimated along a 400-km profile in central Poland crossing the Malopolska Massif (MM), the Lysogory Unit (LU), the Trans-European Suture Zone (TESZ) and ending at the East European Craton (EEC). Magnetotelluric transfer functions, corresponding to 20 sites, were supplemented by magnetovariational responses obtained at the geomagnetic observatories situated at the same tectonic units. Such a combination made it possible to extend the initial period range, which is from fractions of a second to several hours, up to months in order to reliably cover crustal and upper-mantle depths. The geoelectrical structures, revealed using 2-D inversions, do not contradict the known features of the lithosphere structure determined using seismic and gravity data along the profile. The subsurface conductance, varying from approximately 10 Siemens at the inner part of the EEC to about 600 Siemens in the TESZ, is produced by sediments, the deep part of which contains conductive, highly mineralized water. The existence of two crustal conductive faults at the southwest and northeast of the TESZ were established mainly by the use of induction arrows. It was also revealed that rather high mantle conductivity beneath the MM, LU and TESZ at depths of about 150-200 km contrasts with the resistive upper mantle of the EEC. This can be interpreted as the decrease of asthenosphere conductance and/or as its submersion beneath the EEC. Generally, the results confirm the idea that the TESZ forms not only specific seismic boundaries but also causes peculiar conductivity anomalies in the crust and upper mantle.

    The power of the European Central Bank is the main source of Treaty on European Union,Treaty on the Functioning of the European Union,protocol on "the statutes of the European system of central banks and the European Central Bank "and the EU legislation.In terms of power source,there are indeed some of the powers that come from ei-ther agreements or negotiations.But this paper finds that both agreement or negotiation actually belong to the areas of le-gal power by studying the different levels of power and its relevant legal regulations.So the power of the European Cen-tral Bank is defined as the legal power to be the most accurate.%欧洲中央银行的权力主要来源于《欧洲联盟条约》、《欧洲联盟运行条约》、“欧洲中央银行体系和欧洲中央银行规约”以及欧盟内部立法。以权力来源角度而言,的确有部分权力来源于协定或议定,从权力的不同层面以及权力的法律规制视角研究发现协定权力或议定权力实际上均属于法定权力的范畴。因此将欧洲中央银行的权力界定为法定权力才是最为准确的。

    Full Text Available Total factor productivity is a method of measuring overall productivity of businesses, industries or economies. It is an approach which is recently becoming popular among government regulatory agencies when applying the so-called performance-based regulation. This principle induces regulated companies (for instance, electricity or natural gas distributors to behave efficiently even if their industries are not exposed to competitive pressures, since they are rewarded for being more productive than other firms in the industry, and penalized in the opposite case. The aim of this article is to deal with the question what are the main data issues when comparing total factor productivity among firms or industries with focus on the Central European region, which is very heterogeneous in terms of geographic, social, economic and historic conditions. In the first part, we introduce total factor productivity and the most common methods of its measurement � Malmquist and T�rnqvist indexes. Consequently, we divide the data issues into separate categories and discuss them more in detail. The first category of issues is related to defining the set of comparable firms. Many factors, such as the degree of competition in the market, the extent of government regulation, economies of scale, firm size, geographical conditions and historic development have to be taken into consideration. The second category is associated with specifying the time period. TFP estimates should be based on long time series and the period should include the whole business cycle and be representative and exclude extraordinary events. The third group of issues is related to defining and measuring the inputs and outputs. Since a number of difficulties are associated with labor input measurement, it is often included into operating expenditures along with materials and services. The measurement of capital is even more contentious. The outputs should reflect performance

  1. "Professionalization" and "confessionalization": the place of physics, philosophy, and arts instruction at Central European academic institutions during the Reformation era.

    Freedman, J S

    2001-01-01

    During the sixteenth and early seventeenth centuries, physics was regularly taught as part of instruction in philosophy and the arts at Central European schools and universities. However, physics did not have a special or privileged status within that instruction. Three general indicators of this lack of special status are suggested in this article. First, teachers of physics usually were paid less than teachers of most other university-level subject-matters. Second, very few Central European academics during this period appear to have made a career out of teaching physics. And third, Reformation Era schools and universities in Central Europe emphasized language instruction; such instruction not only was instrumental in promoting the confessional--i.e., Calvinist, Lutheran, and Roman Catholic--agendas of those same schools and universities, but also helped to prepare students for service in nascent but growing state governments.

    2012-04-01

    The INCA-CE (Integrated Nowcasting through Comprehensive Analysis - Central Europe) project aims at implementing a transnational weather information system as well as applications for different socio-economic sectors to reduce risks of major economic damage and loss of life caused by severe weather. Civil protection and also stakeholders from economic sectors are in a growing need of accurate and reliable short-term weather forecasts. Within INCA-CE, a state-of-the art nowcasting system (INCA) is implemented at weather services throughout the European Union's CE (Central Europe) Programme Area, providing analyses and short term forecasts to the aforementioned end-users. In a coherent approach, the INCA (Integrated Nowcasting through Comprehensive Analysis) system will be adapted for implementation and use in a number of partner countries. Within transregional working groups, the gap between short-term weather information and its downstream activities in hydrological disaster management, civil protection and road management will be bridged and best practice management and measure plans will be produced. A web-based platform for outreach to related socio-economic sectors will initiate and foster a dialogue between weather services and further stakeholders like tourism or the insurance sector, flood authorities for disaster management, and the construction industry for cost-efficient scheduling and planning. Furthermore, the project will produce a compact guideline for policy makers on how to combine structural development aspects with these new features. In the present paper, an outline of the project implementation, a short overview about the INCA system and two case studies on precipitation nowcasts will be given. Moreover, directions for further developments both within the INCA system and the INCA-CE project will be pointed out.

    Full Text Available The evolution of the Western world has drawn on theoretical structures of classical and neoclassical liberalism for its explanatory support and sources of inspiration for centuries. Against this ideological background, institutionalists aim at showing that growth is a process of transformation, a double change: an economic and an institutional one. In this analysis, our purpose is to highlight the importance of informal institutional arrangements and their quality in explaining the disparities of revenues and developments between countries. In our approach, we will consider several indicators meant to highlight various aspects of research. The approach proposed is a transversal-comparative one and static methods pertain to uni- and multivariate analysis. The results obtained suggest the existence of major differences within the Central and East European area as far as informal institutions are concerned; moreover, the analysis conducted confirms the existence of a significant relation between the level of development and the structure of informal arrangements such as: trust level, bribe culture and corruption control.

    Full Text Available Main activity in the foreign trade policy of the Republic of Macedonia during the past 10 years was the integration of the country on the Central European Free Trade Agreement – (CEFTA. The reason for this is the expectation that the membership of the Republic of Macedonia in CEFTA will significantly contribute to the continual efforts for strengthening the regional trade cooperation, further liberalisation of foreign trade exchange, and continuation of activities for harmonisation of trade rules with international standards. Additionally, CEFTA 2006 provides a much more comprehensive framework for development of mutual relations and economic cooperation among the countries of South Easte Europe. We will explain the concept of development of economic diplomacy in the Republic of Macedonia as a tool for supporting Macedonian economy. The purpose of these activities is to present the Republic of Macedonia as an attractive destination for foreign investments through the promotion of business advantages, and giving incentive to Macedonian export, as well as through strengthening of the country’s position as a attractive touristic destination.

    Full Text Available After 1990, the Central and Eastern European (CEE countries lowered the barriers to FDIs. Of course, many other developments were taking place at the same time: increasing openness to trade, privatization of previously government-owned production, and many other changes as these countries moved in various degrees from socialist to market economies and democratic governments. They privatized many state-owned enterprises, signed foreign trade agreements with other countries in the region, and have generally achieved a significant level of macroeconomic stability with improved growth rates. They also experienced a significant increase in FDI. As a consequence, the ratio of inward FDI to the CEE countries studied here in total world FDI inflows increased more than three-fold. Over the same period, these countries also achieved a substantial increase in their exports, especially towards Western Europe. We present in this paper the relation between the FDIs and exports in the CEE countries during 1990-2010 using statistic data analysis and literature review and underline the factors that determined an increase of exports in these countries. Despite other CEE countries that succeeded to attract many export-oriented FDIs, Romanian case is different because of many local specific factors such as an insufficient local production and a tight fiscal policy.

  6. A two-step multiplex PCR system identifying Central European fish species

    Johannes Oehm

    2015-12-01

    Full Text Available The morphological identification of fish samples can be difficult, for example, when dealing with eggs, larvae, tissue samples, or dietary samples of piscivores. Hard parts such as otoliths, chewing pads, pharyngeal bones or scales can enable morphological identification if present. However, species-specific identification is often not possible, especially in species-rich groups like the cyprinids. Here, we present a two-step multiplex PCR system, tailored for rapid, sensitive, and specific molecular detection of Central European fish species. It is composed of six assays, covers 79 fish and lamprey species, and enables the identification of 31 species, six genera, two families, two orders, and two fish family clusters. This novel approach is tailored for samples with bad DNA quality and has been successfully applied to identify fish prey in feces of the Eurasian otter, the Common Kingfisher, as well as feces and regurgitated pellets of cormorants. More than 4,000 dietary samples of the latter were collected within a two-year field study in the Alpine foreland. These samples have already been analyzed cost-effectively with the presented approach thus generating a detailed picture of cormorant diet in relation to fish phenology. The high sensitivity and specificity of the multiplex PCR system makes it also suitable for applications outside the field of trophic ecology such as the identification of juvenile fish, environmental monitoring, or environmental DNA studies.

    Transferability of current evidence and expressing value of innovative pharmaceuticals according to health system objectives Due to the scarcity of healthcare resources, decision-makers often expect monetary benefits--including cost savings or productivity gain--from innovative medicines. Manufacturers try to fulfill this expectation by expressing the benefits of innovative technologies in monetary units citing approaches from the scientific literature. Unfortunately, currently available evidence has limited relevance and transferability in Central-Eastern European (CEE) countries. This study aims to summarize how innovative pharmaceuticals in CEE countries may contribute to WHO-defined health system objectives, including health gain, equity in health, financial protection, responsiveness, equity in finance and financial sustainability. References in this study are also mainly based on international examples; therefore, additional policy research from CEE countries is necessary to validate assumptions. If CEE politicians can rely on credible arguments based on local research evidence, they may improve long-term strategies and policy decisions related to healthcare innovation. PMID:24350863

    Agricultural management practices and land use change at grassland sites can have a strong impact on annual carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) budgets. At the same time emissions of CH4 and N2O can contribute to an increase of the global warming potential (GWP) of an ecosystem by offsetting concurrent CO2 uptake in terms of CO2-equivalents. It is therefore necessary to quantify long-term fluxes of all three compounds in order to reliably assess the climatic impact of management activities and the effectiveness of greenhouse gas (GHG) mitigation strategies. In this presentation we give an overview of the GHG exchange of eight managed Central European grassland sites along an elevation and land use intensity gradient. Fluxes of the three major GHGs CO2, CH4 and N2O were calculated using the eddy covariance or chamber technique. The investigated grasslands were different with regard to the amount of fertilizer input, frequency of cuts and grazing duration and intensity. In this presentation we focus on time periods when measurements of all three compounds were available and investigate common features among observed CH4 and N2O exchange patterns at the different grassland sites. We analyze these observations in relation to management activities and concurrently measured biotic / abiotic parameters. For field sites where long-term measurements are available we evaluate the impact of CH4 and N2O fluxes on the annual GWP.

    Full Text Available The aim of this paper is to quantify the long run and short run relationship between debt and economic activity in Central, Eastern and Southeastern European countries. In order to investigate the impact of public debt on economic growth, the paper uses pooled mean group estimator (PMG for the period between 2000 and 2011. A battery of panel unit root as well as panel cointegration tests is used prior to performing the dynamic panel analysis based on PMG estimator. According to the empirical results, in the long-run debt significantly influences the GDP growth having a negative sign as expected and pointing out that government gross debt lowers the GDP growth. In the short run, debt has statistically significant negative influence on the GDP growth as well, controlling for other determinants of growth (trade openness, total investment and industry value added. Designing policy frameworks that encourage export, promote industrial development and create better environment for long-term investment should foster sustainable growth. Therefore, we find that a credible fiscal consolidation strategy is needed combined with policies to promote lasting growth in order to reach debt-stabilizing levels.

    Genomically stable gastric cancers (GCs) are enriched for the diffuse phenotype and hotspot mutations of RHOA. Here we aimed to validate the occurrence, phenotype and clinicopathological characteristics of RHOA mutant GCs in an independent Central European GC cohort consisting of 415 patients. The RHOA genotype (exon 2 and 3) was correlated with various genotypic, phenotypic and clinicopathological patient characteristics. Sixteen (3.9%) tumours had a RHOA mutation including four hitherto unreported mutations, that is, p.G17Efs*24, p.V24F, p.T37A and p.L69R. RHOA mutation was more prevalent in women (5.4% vs 2.8%), distal GCs (4.5% vs 2.4%), in poorly differentiated GCs (G3/G4; 4.8% vs 1.1%), T1/T2 tumours (6.2% vs 3.1%) and lacked distant metastases. Nine RHOA mutant GCs had a diffuse, four an intestinal, two an unclassified and one a mixed Laurén phenotype. KRAS and RHOA mutations were mutually exclusive. A single case showed both a RHOA and a PIK3CA mutation. No significant difference was found in the overall survival between RHOA mutant and wildtype GCs. Our study confirms the occurrence and clinicopathological characteristics of RHOA hotspot mutations in an independent patient cohort. However, we found no evidence for a prognostic or growth advantageous effect of RHOA mutations in GC. PMID:26251521

    Full Text Available Abstract
    Between 2003 and 2006, a live-trapping of European wildcats (Felis silvestris was carried out in the Apennines (central Italy. Double-door tunnel cage traps were set along trap-lines. A box containing live quails as bait was securely attached to the side of each cage. Trapping was carried out in 8 sessions at a total of 60 trap-sites, mainly inside woods (65%. The distance between the traps ranged from 146 m to 907 m and the length of each trap-line ranged from 541 m to 2632 m. There were 16 captures of 11 different wildcats, the capture success rate being 1 wildcat/209 trap-days. Nine males and 2 females were caught, suggesting sex-biased trapping selection. In addition to wildcats, 20 non-target species were captured during the 8 sessions. No animal was injured by the traps and no wildcat was endangered by narcosis or handling. The technique proved to be effective for future field studies that envisage the radio-tracking of wildcats.

    Cattura e immobilizzazione del gatto selvatico in Italia centrale.
    Tra il 2003 e il 2006 è stato svolto un programma di ricerca sul gatto selvatico europeo (Felis silvestris in un'area dell'Appennino centrale. Trappole a tunnel a doppio ingresso sono state distribuite lungo delle line-trap; a ciascun dispositivo è stato associato un box che ospitava esche vive (quaglie. Sono state effettuate 8 sessioni di trappolamento per un totale di 60 siti trappola, perlopiù in aree boscate (65%. La distanza tra le trappole variava da 146 m a 907 m mentre la lunghezza delle line-trap variava tra 541 m a 2632 m. I 16 eventi di cattura hanno permesso di marcare 11 individui diversi, 9 maschi e 2 femmine. La differenza del numero di catture tra maschi e femmine è probabilmente da attribuire ad una diversa selettività delle trappole. Durante le 8 sessioni, oltre al gatto selvatico, sono state catturate altre

    The region of the Central and Eastern Europe is an area characterised by a relatively high seismicity. The active seismogenic structures and the related potentially destructive events are located in the proximity of the political boundaries between several countries existing in the area. An example is the seismic region between the NE Italy (FVG, Trentino-Alto Adige and Veneto), Austria (Tyrol, Carinthia) and Slovenia. So when a destructive earthquake occurs in the area, all the three countries are involved. In the year 2001 the Agencija Republike Slovenije za Okolje (ARSO) in Slovenia, the Department of Mathematics and Geoscience of the University of Trieste (DMG), the OGS (Istituto Nazionale di Oceanografia e di Geofisica Sperimentale) in Italy and the Zentralanstalt für Meteorologie und Geodynamik (ZAMG) in Austria signed an agreement for the real-time seismological data exchange in the Southeastern Alps region. Soon after the Interreg IIIa Italia-Austria projects "Trans-National Seismological Networks in the South-Eastern Alps" and "FASTLINK" started. The main goal of these projects was the creation of a transfrontier network for the common seismic monitoring of the region for scientific and civil defense purposes. During these years the high quality data recorded by the transfrontier network has been used, by the involved institutions, for their scientific research, for institutional activities and for the civil defense services. Several common international projects have been realized with success. The instrumentation has been continuously upgraded, the installations quality improved as well as the data transmission efficiency. In the 2013 ARSO, DMG, OGS and ZAMG decided to name the cooperative network "Central and Eastern European Earthquake Research Network - CE3RN". The national/regional seismic networks actually involved in the CE3RN network are: • Austrian national BB network (ZAMG - OE) • Friuli Veneto SP network (OGS - FV) • Friuli VG

    Full Text Available While the European Union keeps taking pride in putting forward the existence of a European Social Model, no study or project was carried out in order to foresee the enlargement effects on this model and mainly how the latter could be successfully implemented by the new Member States, having regard to their own characteristics. It is no coincidence that the references to the European Social Model multiplied during the period when the EU was facing its own enlargement. More and more questions were raised concerning the new Member States convergence capacity, as regards Central and Eastern Europe countries in particular, with all the European Union social rules. The trends in the new Member States, as well as their convictions or their lack of conviction, concerning the European Social Model, have major implications on the tomorrow’s social Europe. In which direction is it heading in an enlarged 25 or 27 nations European Union? This study is aimed at answering at this question having regard, in particular, to the economical and social characteristics of the new Member States and to the possible sources that might give rise to blockings in the social field.

    The Holocene climate and vegetation dynamics in the broad-leaved forest zone of the central part of the East European plain have been reconstructed on the base of pollen, plant macrofossil, testate amoebae and radiocarbon data from the mire Klukva (N 53.834812, E 36.252488), located in the kast depression in the Upper Oka River basin (Tula region, European Russia). The reconstruction of main parameters of past climate (the mean annual temperature precipitation) was carried out by the "Best Modern Analog" approach. Reconstructions of vegetation show that in the early Holocene the territory was occupied mainly by birch and pine-birch forests. Significant changes in the plant cover of the Upper Oka River basin are attributed to the 7.5 cal kyr BP). The climatic conditions were favorable for development of the broad-leaved forests those persisted in this area up to industrial period. In the 17th century, when the population density greatly increased and watersheds were ploughed, natural vegetation communities were gradually destroyed and transformed into agricultural landscapes. According to obtained climatic reconstructions the period 10-8.5 cal kyr BP was relatively cold and wet, when the mean annual temperature was in 3°C lower and precipitation was in 50-100 mm higher then nowadays. The significant climate warming occurred in about 7.0-5.0 cal kyr BP (The Holocene thermal maximum): the mean annual temperature in 2°C exceeded the modern value and precipitation was close to that. The environment conditions were drier due to decrease of effective moisture. In the second part of the Holocene the sequence of second-, and even third-order climatic oscillations expressed against the background of the overall slight trend towards cooling have been determined. The most pronounced cool and wet intervals were reconstructed in 2.5-2.0 cal kyr BP and 1.5-1.3 cal kyr BP. The mean annual temperature decreased in 1.5-2 °C and precipitation rose in 200 mm in compare to modern

  15. Cladogenesis and morphological diversification in passerine birds.

    Morphological diversity tends to increase within evolving lineages over time, but the relative roles of gradual evolutionary change (anagenesis) and abrupt shifts associated with speciation events (cladogenesis, or 'punctuated equilibrium') have not been resolved for most groups of organisms. However, these two modes of evolution can be distinguished by the fact that morphological variance increases in proportion to time under anagenesis, and in proportion to the logarithm of the number of species under cladogenesis. Although species and time are themselves correlated, multiple regression analysis provides a statistical framework for partitioning their relative contributions. In this study, I use multiple regressions to evaluate the effects of time and species number on morphological diversity within clades of passerine birds. The results show clearly that number of species exerts a strong influence on morphological variance independent of time, but that time has no unique effect. Thus, morphological evolution in birds seems to be associated with cladogenesis. How lineage splitting promotes morphological diversification poses an important challenge to ecologists and evolutionary biologists. PMID:15254535

    ¹³⁷Cs - the main long-living anthropogenic radionuclide - arrived in mass at Russian terrestrial ecosystems after nuclear tests in the atmosphere in 1960-yy. and after Chernobyl accident in 1986 y., but in spite of a long period since these events soil cover contamination by ¹³⁷Cs is considered as extremely resistant due to its firmly fixation by soil solid matter and a long half-life of the radionuclide. Wide-scale investigation in maximal diversity of natural, semi-natural and anthropogenic landscapes of Central European Russia (more than 400 soils samples from Vologda, Yaroslavl, Ivanovo, Tver regions which are representative for the southern taiga zone) demonstrates that modern average specific activity of ¹³⁷Cs in the upper 15-cm layer of soil is 11±3 Bq/kg (contamination density 0.05±0.01 Ci/km²), that is fully ecologically acceptable. It is important that the average concentrations of ¹³⁷Cs in the soil cover of individual regions are close to each other. The most likely these average values are approximate assessment of background radioactive contamination of soils in central European Russia outside of the immediate Chernobyl trace. At the same time approximately 3% of soils are characterized by elevated ¹³⁷Cs content - 62-98 Bq/kg (0.24-0.43 Ci/km²), that indicates the presence of low radioactive spots on the territory and may be considered as local Chernobyl fallout. All of them attribute with forest soils which are commonly characterized by considerably more high accumulation of ¹³⁷Cs (18±5 Bq/kg, 0.06±0.01 Ci/km²) due to advanced absorbing surface of trees. Agricultural lands (plagued or under meadows) and soils of industrial plots with scarce vegetation contain only 6±2 Bq/kg (0.03±0.01 Ci/km²) of ¹³⁷Cs. About 84-92% of ¹³⁷Cs are concentrated in the upper 15-cm layer of natural soils or in Ap horizon of plagued soils, thus vertical migration of radionuclide is very slow in spite of ~30 years after Chernobyl

    For the purpose of qualifying and quantifying the impact of urban emission from Central European cities on the present-day regional air quality, the regional climate model RegCM4.2 was coupled with the chemistry transport model CAMx, including two-way interactions. A series of simulations was carried out for the 2001-2010 period either with all urban emissions included (base case) or without considering urban emissions. Further, the sensitivity of ozone production to urban emissions was examined by performing reduction experiments with -20 % emission perturbation of NOx and/or non-methane volatile organic compounds (NMVOC). The modeling system's air quality related outputs were evaluated using AirBase, and EMEP surface measurements showed reasonable reproduction of the monthly variation for ozone (O3), but the annual cycle of nitrogen dioxide (NO2) and sulfur dioxide (SO2) is more biased. In terms of hourly correlations, values achieved for ozone and NO2 are 0.5-0.8 and 0.4-0.6, but SO2 is poorly or not correlated at all with measurements (r around 0.2-0.5). The modeled fine particulates (PM2.5) are usually underestimated, especially in winter, mainly due to underestimation of nitrates and carbonaceous aerosols. European air quality measures were chosen as metrics describing the cities emission impact on regional air pollution. Due to urban emissions, significant ozone titration occurs over cities while over rural areas remote from cities, ozone production is modeled, mainly in terms of number of exceedances and accumulated exceedances over the threshold of 40 ppbv. Urban NOx, SO2 and PM2.5 emissions also significantly contribute to concentrations in the cities themselves (up to 50-70 % for NOx and SO2, and up to 60 % for PM2.5), but the contribution is large over rural areas as well (10-20 %). Although air pollution over cities is largely determined by the local urban emissions, considerable (often a few tens of %) fraction of the concentration is attributable to

    Full Text Available High-resolution (5×5km2$5\\times5\\,\\text{km}^2$ gridded daily data sets of surface air temperature (DWD/BfG-HYRAS-TAS and relative humidity (DWD/BfG-HYRAS-HURS are presented in this study. The data sets cover Germany and the bordering river catchments and last from 1951 to 2006. Their data bases consist of daily station observations from Austria, Belgium, Czech Republic, France, Germany, Luxembourg, the Netherlands and Switzerland. The interpolation of the measurement data to the regular grid is performed using a method based upon Optimal Interpolation. A first climatological analysis for Germany and Central European river catchments of first and second order is performed. For the Rhine river catchment a summer mean temperature of 16.1 °C and relative humidity of 74 % are found. In contrast, the mean temperature of heat summer 2003 amounts to 19.9 °C with a related relative humidity of 65 % in this river catchment. The extreme character of this summer is also remarkable in the presented climate indices, e.g., the increased amount of summer hot days. The first validations of both data sets reveal a bias within the range of the provided data precisions. In addition, an elevation dependency of error scores is identified for temperature. Error scores increase with an increasing station height because height differences between station and grid cell increases with height. A comparison of HYRAS-TAS to another gridded temperature data set reveals a good agreement with again fewer differences at lower altitudes. The presented DWD/BfG-HYRAS data sets have a high spatial and temporal resolution which is unique for Germany and the bordering river catchments so far. They have a high potential for detailed studies of smaller scale structures in Central Europe and are already used as input for hydrological impact modelling, as climatological reference and for bias correction of regional climate models within the German research project KLIWAS

    Central European grasslands are characterized by a wide range of different agricultural practices along an altitudinal and management gradient, reaching from low pastures and meadows up to high alpine grasslands above the tree line. In the future, the intensification of already available agricultural land as a consequence of increased demand for feed and food will play an important role because of the scarcity of unused, productive land. The land use intensity strongly affects the exchange of trace gases between the biosphere and atmosphere. Therefore, the greenhouse gas (GHG) reduction potential for different farming strategies needs to be quantified before effective greenhouse gas mitigation strategies can be introduced. Direct measurements of long-term grassland GHG exchange at ecosystem scale along altitudinal and management gradients can help in identifying key processes that lead to GHG emissions. In this synthesis we investigated GHG fluxes with a focus on N2O and CH4 from 15 grassland sites, quantified by means of the eddy covariance or chamber technique. Grasslands were a source of N2O, with the exception of one abandoned site, while they were a source or small sink for CH4. The predictive power of soil temperature and water-filled pore space for N2O and CH4 flux patterns during snow-free time periods in-between management events was generally low but varied considerably across the year. However, setting fluxes in relation to classes of the two soil parameters revealed favorable conditions ('sweet spots') for N2O and CH4 emissions for some sites. In addition, fertilization had a clear impact on N2O and CH4 fluxes, with emission peaks on the day of fertilization or one day later. N2O-N emission factors at fertilized sites were found to be slightly higher than the IPCC Tier 1 approach, ranging between 1.31 and 1.53 %, depending on the gap-filling method to calculate yearly cumulative N2O emissions.

    The Central European Watershed divides the Rhine-Main catchment and the Danube catchment. In the Early Medieval period, when ships were important means of transportation, Charlemagne decided to link both catchments by the construction of a canal connecting the Schwabian Rezat and the Altmühl rivers. The artificial waterway would provide a continuous inland navigation route from the North Sea to the Black Sea. The shortcut is known as Fossa Carolina and represents one of the most important Early Medieval engineering achievements in Europe. Despite the important geostrategic relevance of the construction it is not clarified whether the canal was actually used as a navigation waterway. We present new geophysical data and in situ findings from the trench fills that prove for the first time a total length of the constructed Carolingian canal of at least 2300 metres. We have evidence for a conceptual width of the artificial water course between 5 and 6 metres and a water depth of at least 60 to 80 cm. This allows a crossing way passage of Carolingian cargo scows with a payload of several tons. There is strong evidence for clayey to silty layers in the trench fills which reveal suspension load limited stillwater deposition and, therefore, the evidence of former Carolingian and post-Carolingian ponds. These findings are strongly supported by numerous sapropel layers within the trench fills. Our results presented in this study indicate an extraordinarily advanced construction level of the known course of the canal. Here, the excavated levels of Carolingian trench bottoms were generally sufficient for the efficient construction of stepped ponds and prove a final concept for a summit canal. We have evidence for the artificial Carolingian dislocation of the watershed and assume a sophisticated Early Medieval hydrological engineering concept for supplying the summit of the canal with adequate water.

    Plant traits have been widely used to characterize different aspects of the ecology of plant species. Despite its wide distribution and its proven significance at the level of individuals, communities, and populations, the ability to form mycorrhizal associations has been largely neglected in these studies so far. Analyzing plant traits associated with the occurrence of mycorrhizas in plants can therefore enhance our understanding of plant strategies and distributions. Using a comparative approach, we tested for associations between mycorrhizal status and habitat characteristics, life history traits, and plant distribution patterns in 1752 species of the German flora (a major part of the Central European flora). Data were analyzed using log-linear models or generalized linear models, both accounting for phylogenetic relationships. Obligatorily mycorrhizal (OM) species tended to be positively associated with higher temperature, drier habitats, and higher pH; and negatively associated with moist, acidic, and fertile soils. Competitive species were more frequently OM, and stress tolerators were non-mycorrhizal (NM), while ruderal species did not show any preference. Facultatively mycorrhizal (FM) species showed the widest geographic and ecological amplitude. Indigenous species were more frequently FM and neophytes (recent aliens) more frequently OM than expected. FM species differed markedly from OM and NM species in almost all analyzed traits. Specifically, they showed a wider geographic distribution and ecological niche. Our study of the relationships between mycorrhizal status and other plant traits provides a comprehensive test of existing hypotheses and reveals novel patterns. The clear distinction between FM and OM + NM species in terms of their ecology opens up a new field of research in plant-mycorrhizal ecology. PMID:23923502

    Full Text Available Since January 2009 highly time-resolved mercury speciation measurements in ambient air are carried out at the Central European German EMEP monitoring station and measurement site of the German Federal Environment Agency “Waldhof“, providing the longest Central European dataset for mercury species. First statistical analyses do not indicate long term trends for the concentrations of gaseous elemental mercury (GEM and particle bound mercury (TPM. A potential increasing trend for reactive gaseous mercury (RGM will have to be verified in the coming years and should be regarded as indicative only at present. A seasonal cycle for TPM could be observed with higher concentrations during winter time. Furthermore a diurnal cycle for RGM is apparent with highest concentrations in the early afternoon.

    A European goldfinch (Carduelis carduelis), a canary (Serinus canaria), and a lovebird (Agapornis roseicollis) captive-bred at three different private aviaries in Spain were submitted for necropsy with a history of weakness and ruffled feathers, weight loss associated with glossitis, and respiratory disease, respectively. Microscopically, enterocytes in the jejunum and ileum contained colonies of gram- and Stamp-positive, oval to elliptical microorganisms within parasitophorous vacuoles in the apical cytoplasm. Nested PCR using MSP primers that target microsporidian RNA genes produced amplicons of expected size for Encephalitozoon species, and analysis of forward and reverse DNA sequences confirmed the presence of Encephalitozoon hellem in all cases. The main cause of death of all three birds consisted of concurrent infections. However, intestinal encephalitozoonosis may have contributed to exacerbated catabolism. Encephalitozoonosis (or microsporidiosis) has been rarely described in passerine birds. PMID:26921040

    Abstract In this data paper, a dataset of passerine bird communities is described in Sierra Nevada, a Mediterranean high mountain located in southern Spain. The dataset includes occurrence data from bird surveys conducted in four representative ecosystem types of Sierra Nevada from 2008 to 2015. For each visit, bird species numbers as well as distance to the transect line were recorded. A total of 27847 occurrence records were compiled with accompanying measurements on distance to the transect and animal counts. All records are of species in the order Passeriformes. Records of 16 different families and 44 genera were collected. Some of the taxa in the dataset are included in the European Red List. This dataset belongs to the Sierra Nevada Global-Change Observatory (OBSNEV), a long-term research project designed to compile socio-ecological information on the major ecosystem types in order to identify the impacts of global change in this area.

With the Euro, came the establishment of the European Central Bank. Thus this study seeks to investigate the flaws in the formation of the European Central Bank that surfaced during the major economic crisis in Europe. The crisis revealing the gaps in the formation and structure of the European central bank have created major challenges for the Economic and Monetary Union (EMU. Through an extant review of literature the study will examine the East African Community Countries, investigating the ties they have to the euro zone to analyse how the crisis has affected them. Furthermore, the study will analyse what would happen to the growth patterns of the East African Countries and the various prospects they may have should the Eurozone come to an end.

    A series of Multilingual planetary maps has been published by the Cosmic Materials Space Research Group of the Eötvös Loránd University (Budapest, Hungary) with consultations by Russian and German colleagues. The maps are a result of a cooperation of MIIGAiK (which offered the base maps), ELTE, the Copernicus Observatory and Planetarium in Brno, the Zagreb Astronomical Observatory, the Jagellonian University Observatory, the Tectonics and Geological Cartography Section of the Faculty of Geology at Warsaw University and the University of Architecture, Civil Engeneering and Geodesy in Sofia. The series has been initiated by the International Cartographic Association (ICA), Commission on Planetary Cartography (Shingareva et al. 2006). The now complete series has been published from 2001 to 2006: Mars (2001), Venus (2003), Moon (2003), Mercury (2004) and Phobos and Deimos (2006). (Hargitai et al 2001-2006) These maps are more than outreach posters but less than maps for scientific purposes. These give a good overview of the topography and geology of the planets in a global to regional scale. They contain multilingual information concerning planetary science results and specific characteristics of the planetary body relief, placed on the lower margins of the front sides of the maps and the whole back side (geography, geology, stratigraphy, history of discovery and full index of names). These texts appear in Czech, Bulgarian, Hungarian, Croatian, Polish and English. In some cases it was the first time that a particular term (and its definition) was translated into one of these Central European languages. After compiling the first four maps it can be concluded that such work can effectively draw the attention of earth scientists to the specific features - and the mere existence - of other planetary bodies by simply discussing the translation of their terminology. Apart from circulating the maps in classrooms, this might be the most important scientific result of this

  9. Interannual variability of Central European mean temperature in January / February and its relation to the large-scale circulation

    International Nuclear Information System (INIS)

    The Central European temperature distribution field, as given by 11 stations (Fanoe, Hamburg, Potsdam, Jena, Frankfurt, Uccle, Hohenpeissenberg, Praha, Wien, Zuerich and Geneve), is analysed with respect to its year-to-year variability. January-February (JF) average temperatures are considered for the interval 1901-80. An Orthogonal Function (EOF) analysis reveals that the JF temperature variability is almost entirely controlled by one EOF with uniform sign. The second EOF represents only 7% of the total variance and describes a north-south gradient. The time coefficient of the first EOF is almost stationary whereas the second pattern describes a slight downward trend at the northern stations and a slight upward trend at the southern stations. The relationship of the temperature field to the large-scale circulation, represented by the North Atlantic/European sea-level pressure (SLP) field, is investigated by means of a Canonical Correlation (CCA) Analysis. Two CCA pairs are identified which account for most of the temperature year-to-year variance and which suggest plausible mechanisms. The CCA pairs fail, however, to consistently link the long-term temperature trends to changes in the large-scale circulation. In the output of a 100-year run with a coupled atmosphere-ocean model (ECHAM1/LSG), the same CCA pairs are found but the strength of the link between Central European temperature and North Atlantic SLP is markedly weaker than in the observed data.

    Clinopyroxene megacrysts up to few centimetres in size occur in Cenozoic alkaline lavas forming the north-eastern part of Central European Volcanic Province in Lower Silesia (SW Poland). The megacrysts occur, among other, in the Miocene basanite from Ostrzyca Proboszczowicka (bulk rock mg# 0.65-0.66) and in that from Lutynia (Pliocene, K-Ar age: 4.56 +/- 0.2 Ma; Birkenmajer et al. 2002; bulk rock mg# 0.64). The megacrysts typically consist of homogeneous core surrounded by patchy and spongy mantle, which is covered by a thin outermost rim of composition similar to that of the groundmass clinopyroxene occurring in the host basanite. The mantles of the megacrysts have been affected by melting, whereas the cores preserve their primary composition. We compare the core parts of megacrysts in the following. The Ostrzyca clinopyroxene megacrysts contain euhedral apatite intergrowths. The clinopyroxene has the composition of Fe-rich diopside (mg# = 0.61 - 0.70), contain significant sodium (to 0.12 a pfu) and are calcium rich (0.89-0.92 a pfu). The Lutynia megacrysts have the composition of augite and diopside (mg# 0.80-0.83). The sodium content is also high (to 0.12 a pfu), but calcium varies from 0.68 to 0.77 a pfu. The REE concentrations for Lutynia (1-10 x PM) are lower relative to Ostrzyca, enriched 10-100 times relative to PM. In both sites the megacrysts are strongly enriched in LREE relative to HREE and TE are characterized by positive Th, La and Ce anomalies, slight negative Sr and Y anomalies and strong Pb anomaly in the PM normalised patterns. The megacrysts from Ostrzyca reveal slight negative Ti and strong positive Zr and Hf anomalies, whereas those Lutynia have negative Zr anomaly and Ti anomaly is absent. Major and trace element composition shows that the megacrysts from Ostrzyca formed as coarse-grained cumulate at significant depth (lower crust?) from the LREE enriched alkaline melt. That melt was very rich in phosphorous which enabled its saturation in

    We examined how acceptance of euthanasia among the general public has changed between 1981 and 2008 in western and central and eastern European (CEE) countries using data of the European Values Surveys. Data were collected in 1981, 1990, 1999 and 2008 for 13 western European countries and in 1990, 1999 and 2008 for 10 CEE countries. Euthanasia acceptance increased each decade up until 2008 in 11 of 13 western European countries; in CEE countries, it decreased or did not increase between 1999-2008 in 8 of 10 countries. A number of explanations for and implications of this apparent east-west polarization are suggested.

    The Jesuits acted as intermediate in the exchange of know-how between Europe and China. In modern Chinese eyes they were also somewhat viewed as spies, who helped European military and economic victories in the mid-19th century. Modern China is now as strong as it was in the times of Old Jesuit Society, therefore the Europocentric history of science must be rewritten from the standpoint of today’s winning Chinese economy. What kind of science will Western Civilization import from the future Chinese literati? The Jesuits’ transfer of European Sciences to the Far-Easterners caused the reverse impact from seemingly less developed centers of Far East that was felt in Jesuits’ times, but much more is to follow in the near future. We could expect the fundamental future Chinese achievements in cosmology, especially in Einstein’s general theory of relativity.

    With continuing tropical deforestation, there is increased concern for birds that depend on forest habitats in Latin America. During the past 10 northern winters, we have conducted quantitative studies of habitat use by wintering migrant songbirds and by residents in the Greater Antilles, Mexico, Central America, and northern South America. Many migrants, but few residents, winter in forest fragments and in certain arboreal agricultural habitats (citrus, cacao, shade coffee). Many other agricultural habitats (sun coffee, mango, commercial banana plantations, and heavily grazed pasture) are avoided by most birds. Some species, such as thrushes and ground-feeding warblers, depend on closed-canopy forest. Some, such as Northern Waterthrush (Seiurus noveboracensis) and Prothonotary Warbler (Protonotaria citrea), winter primarily in mangroves or other swamp forests. The majority of neotropical migrant passerines winter in forest fragments and certain agricultural habitats, as well as mature forest; but many resident species, especially suboscines (Furnariidae, Dendrocolaptidae, Formicariidae, Papridae), are heavily impacted by loss and fragmentation of the forest.

    Ethnic Belarusians make up more than 80% of the nine and half million people inhabiting the Republic of Belarus. Belarusians together with Ukrainians and Russians represent the East Slavic linguistic group, largest both in numbers and territory, inhabiting East Europe alongside Baltic-, Finno-Permic- and Turkic-speaking people. Till date, only a limited number of low resolution genetic studies have been performed on this population. Therefore, with the phylogeographic analysis of 565 Y-chromosomes and 267 mitochondrial DNAs from six well covered geographic sub-regions of Belarus we strove to complement the existing genetic profile of eastern Europeans. Our results reveal that around 80% of the paternal Belarusian gene pool is composed of R1a, I2a and N1c Y-chromosome haplogroups – a profile which is very similar to the two other eastern European populations – Ukrainians and Russians. The maternal Belarusian gene pool encompasses a full range of West Eurasian haplogroups and agrees well with the genetic structure of central-east European populations. Our data attest that latitudinal gradients characterize the variation of the uniparentally transmitted gene pools of modern Belarusians. In particular, the Y-chromosome reflects movements of people in central-east Europe, starting probably as early as the beginning of the Holocene. Furthermore, the matrilineal legacy of Belarusians retains two rare mitochondrial DNA haplogroups, N1a3 and N3, whose phylogeographies were explored in detail after de novo sequencing of 20 and 13 complete mitogenomes, respectively, from all over Eurasia. Our phylogeographic analyses reveal that two mitochondrial DNA lineages, N3 and N1a3, both of Middle Eastern origin, might mark distinct events of matrilineal gene flow to Europe: during the mid-Holocene period and around the Pleistocene-Holocene transition, respectively.

    Species of the family Prosthogonimidae are considered the most pathogenic poultry trematodes worldwide, affecting particularly low intensity farming in rural areas. Adults of Prosthogonimus occur mainly in the bursa of Fabricius, oviduct and cloaca of ducks, geese, fowl and other birds feeding at least occasionally on dragonflies or damselflies (Odonata). We analyzed the central European species of the Prosthogonimidae, namely Prosthogonimus cuneatus, Prosthogonimus ovatus, Prosthogonimus pellucidus and Prosthogonimus rarus. We sequenced three nuclear (ITS2) and mitochondrial (CO1, ND1) DNA loci of four species isolated from Anas clypeata, Anas strepera, Anas platyrhynchos, Aythya ferina, Passer domesticus and Turdus merula. Intra- and inter-specific sequence variability revealed that all four species represent distinct well-defined entities. Our data, combined with previously published studies, suggest the return of the name Prosthogonimus rarus Braun, 1901 for Schistogonimus rarus (Braun, 1901). The genus name Schistogonimus Lühe, 1909 is considered a junior synonym of Prosthogonimus Lühe, 1899. We identified the existence of two clades, one represented by P. cuneatus and P. pellucidus, and another one formed by P. ovatus and P. rarus. We also provide comparative measurements of these four central European prosthogonimids, and address their tissue specificity, host-specific prevalence (based on the extensive bird cohort examined in years 1962-2014), and for some bird hosts we address also differences in the prevalence of Prosthogonimus spp. in natural and near-natural wetlands in comparison with fishponds utilized for intense carp production. We provide an updated key to European Prosthogonimus spp. based on their morphological characters. PMID:25724855

    The EU has set high targets to increase the use of renewable energy sources from which a large part has to come from biomass. To meet these targets, a large amount of biomass resources is needed, which requires large areas of land in the EU for energy crop production. However, the availability of good land for energy crop production is limited in Western European countries (WEC). This means that the potential from indigenous biomass resources is not sufficient to meet the set bioenergy targets. At the same time, the expansion of the EU and the inclusion of the Central and Eastern European countries (CEEC) in agricultural and energy EU policies create potential difficulties as well as opportunities. Agriculture plays an important role in the CEEC furthermore, the share of agricultural employment is still large. In the future rationalization of the current agriculture in the CEEC is expected. This will lead to increased productivity and economic performance. On the other hand, unemployment and an increase in abandoned land are expected as well. A study of the technical biomass production potentials in the CEEC shows that in some scenarios the biomass production potential exceeds the current final energy consumption on a country level. The main objectives of this study are: 1) Define the critical factors to set up a stable international biofuel trade between CEEC and WEC, 2) Estimate the cost performance of the energy carriers delivered in the WEC from the CEEC, 3) Analyze the regional differences in cost performance of the energy carriers in the CEEC.

    Ruminant milk and dairy products are important food resources in many European, African, and Middle Eastern societies. These regions are also associated with derived genetic variants for lactase persistence. In mammals, lactase, the enzyme that hydrolyzes the milk sugar lactose, is normally down-regulated after weaning, but at least five human populations around the world have independently evolved mutations regulating the expression of the lactase-phlorizin-hydrolase gene. These mutations result in a dominant lactase persistence phenotype and continued lactase tolerance in adulthood. A single nucleotide polymorphism (SNP) at C/T-13910 is responsible for most lactase persistence in European populations, but when and where the T-13910 polymorphism originated and the evolutionary processes by which it rose to high frequency in Europe have been the subject of strong debate. A history of dairying is presumed to be a prerequisite, but archaeological evidence is lacking. In this study, DNA was extracted from the dentine of 36 individuals excavated at a medieval cemetery in Dalheim, Germany. Eighteen individuals were successfully genotyped for the C/T-13910 SNP by molecular cloning and sequencing, of which 13 (72%) exhibited a European lactase persistence genotype: 44% CT, 28% TT. Previous ancient DNA-based studies found that lactase persistence genotypes fall below detection levels in most regions of Neolithic Europe. Our research shows that by AD 1200, lactase persistence frequency had risen to over 70% in this community in western Central Europe. Given that lactase persistence genotype frequency in present-day Germany and Austria is estimated at 71-80%, our results suggest that genetic lactase persistence likely reached modern levels before the historic population declines associated with the Black Death, thus excluding plague-associated evolutionary forces in the rise of lactase persistence in this region. This new evidence sheds light on the dynamic evolutionary

  7. Nesting and acoustic ecology, but not phylogeny, influence passerine urban tolerance.

    Urbanization is one of the most extensive and ecologically significant changes happening to terrestrial environments, as it strongly affects the distribution of biodiversity. It is well established that native species richness is reduced in urban and suburban areas, but the species traits that predict tolerance to urbanization are yet little understood. In birds, one of the most studied groups in this respect, evidence is appearing that acoustic traits influence urban living, but it remains unknown how this compares to the effects of more obvious ecological traits that facilitate urban living. Therefore, it remains unclear whether acoustic communication is an important predictor of urban tolerance among species. Here, with a comparative study across 140 European and North American passerines, I show that high song frequency, which is less masked by the low-frequency anthropogenic noise, is associated with urban tolerance, with an effect size over half that of the most important ecological trait studied: off-ground nesting. Other nesting and foraging traits accepted to facilitate urban living did not differ for species occurring in urban environments. Thus, the contribution of acoustic traits for passerine urban tolerance approximates that of more obvious ecological traits. Nonetheless, effect sizes of the biological predictors of urban tolerance were low and the phylogenetic signal for urban tolerance was null, both of which suggest that factors other than phenotypic traits have major effects on urban tolerance. A simple possibility is exposure to urbanization, as there was a higher proportion of urban-tolerant species in Europe, which is more urbanized than North America.

    To define the role of birds as reservoirs and disseminators of Borrelia spirochetes, we characterized tick infestation and reservoir competence of migratory passerine birds in Sweden. A total of 1,120 immature Ixodes ricinus ticks were removed from 13,260 birds and assayed by quantitative polymerase chain reaction (PCR) for Borrelia, followed by DNA sequencing for species and genotype identification. Distributions of ticks on birds were aggregated, presumably because of varying encounters with ticks along migratory routes. Lyme borreliosis spirochetes were detected in 160 (14%) ticks. Borrelia garinii was the most common species in PCR-positive samples and included genotypes associated with human infections. Infestation prevalence with infected ticks was 5 times greater among ground-foraging birds than other bird species, but the 2 groups were equally competent in transmitting Borrelia. Migratory passerine birds host epidemiologically important vector ticks and Borrelia species and vary in effectiveness as reservoirs on the basis of their feeding behavior. PMID:16836825

    The relationship between species richness and the occupation of niche space can provide insight into the processes that shape patterns of biodiversity. For example, if species interactions constrained coexistence, one might expect tendencies toward even spacing within niche space and positive relationships between diversity and total niche volume. I use morphological diversity of passerine birds as a proxy for diet, foraging maneuvers, and foraging substrates and examine the morphological space occupied by regional and local passerine avifaunas. Although independently diversified regional faunas exhibit convergent morphology, species are clustered rather than evenly distributed, the volume of the morphological space is weakly related to number of species per taxonomic family, and morphological volume is unrelated to number of species within both regional avifaunas and local assemblages. These results seemingly contradict patterns expected when species interactions constrain regional or local diversity, and they suggest a larger role for diversification, extinction, and dispersal limitation in shaping species richness.

    Full Text Available Abstract Background Following the expansion of the European Union, there has been a large influx of Central and East European (CEE migrants to the UK. CEE men who have sex with men (MSM represent a small minority within this population that are none-the-less important to capture in sexual health research among the CEE migrant community. This paper examines the feasibility of recruiting CEE MSM for a survey of sexual behaviour in London using respondent driven sampling (RDS, via gay websites and in GUM clinics. Methods We sought CEE MSM to start RDS chain referral among GUM clinic attendees, our personal contacts and at gay events and venues in central London. We recruited CEE MSM (n = 485 via two popular websites for gay men in Britain (March-May 2009 and at two central London GUM clinics (n = 51 (July 2008-March 2009. Results We found seventeen men who knew other CEE MSM in London and agreed to recruit contacts into the study. These men recruited only three men into the study, none of whom recruited any further respondents, and RDS was abandoned after 7 months (July 2008-January 2009. Half of the men that we approached to participate in RDS did not know any other CEE MSM in London. Men who agreed to recruit contacts for RDS were rather more likely to have been in the UK for more than one year (94.1% vs 70.0%, p = 0.052. Men recruited through gay websites and from GUM clinics were similar. Conclusions The Internet was the most successful method for collecting data on sexual risk behaviour among CEE MSM in London. CEE MSM in London were not well networked. RDS may also have failed because they did not fully understand the procedure and/or the financial incentive was not sufficient motivation to take part.

  13. The Honey Bee Pathosphere of Mongolia: European Viruses in Central Asia.

    Parasites and pathogens are apparent key factors for the detrimental health of managed European honey bee subspecies, Apis mellifera. Apicultural trade is arguably the main factor for the almost global distribution of most honey bee diseases, thereby increasing chances for multiple infestations/infections of regions, apiaries, colonies and even individual bees. This imposes difficulties to evaluate the effects of pathogens in isolation, thereby creating demand to survey remote areas. Here, we conducted the first comprehensive survey for 14 honey bee pathogens in Mongolia (N = 3 regions, N = 9 locations, N = 151 colonies), where honey bee colonies depend on humans to overwinter. In Mongolia, honey bees, Apis spp., are not native and colonies of European A. mellifera subspecies have been introduced ~60 years ago. Despite the high detection power and large sample size across Mongolian regions with beekeeping, the mite Acarapis woodi, the bacteria Melissococcus plutonius and Paenibacillus larvae, the microsporidian Nosema apis, Acute bee paralysis virus, Kashmir bee virus, Israeli acute paralysis virus and Lake Sinai virus strain 2 were not detected, suggesting that they are either very rare or absent. The mite Varroa destructor, Nosema ceranae and four viruses (Sacbrood virus, Black queen cell virus, Deformed wing virus (DWV) and Chronic bee paralysis virus) were found with different prevalence. Despite the positive correlation between the prevalence of V. destructor mites and DWV, some areas had only mites, but not DWV, which is most likely due to the exceptional isolation of apiaries (up to 600 km). Phylogenetic analyses of the detected viruses reveal their clustering and European origin, thereby supporting the role of trade for pathogen spread and the isolation of Mongolia from South-Asian countries.

    Full Text Available Parasites and pathogens are apparent key factors for the detrimental health of managed European honey bee subspecies, Apis mellifera. Apicultural trade is arguably the main factor for the almost global distribution of most honey bee diseases, thereby increasing chances for multiple infestations/infections of regions, apiaries, colonies and even individual bees. This imposes difficulties to evaluate the effects of pathogens in isolation, thereby creating demand to survey remote areas. Here, we conducted the first comprehensive survey for 14 honey bee pathogens in Mongolia (N = 3 regions, N = 9 locations, N = 151 colonies, where honey bee colonies depend on humans to overwinter. In Mongolia, honey bees, Apis spp., are not native and colonies of European A. mellifera subspecies have been introduced ~60 years ago. Despite the high detection power and large sample size across Mongolian regions with beekeeping, the mite Acarapis woodi, the bacteria Melissococcus plutonius and Paenibacillus larvae, the microsporidian Nosema apis, Acute bee paralysis virus, Kashmir bee virus, Israeli acute paralysis virus and Lake Sinai virus strain 2 were not detected, suggesting that they are either very rare or absent. The mite Varroa destructor, Nosema ceranae and four viruses (Sacbrood virus, Black queen cell virus, Deformed wing virus (DWV and Chronic bee paralysis virus were found with different prevalence. Despite the positive correlation between the prevalence of V. destructor mites and DWV, some areas had only mites, but not DWV, which is most likely due to the exceptional isolation of apiaries (up to 600 km. Phylogenetic analyses of the detected viruses reveal their clustering and European origin, thereby supporting the role of trade for pathogen spread and the isolation of Mongolia from South-Asian countries. In conclusion, this survey reveals the distinctive honey bee pathosphere of Mongolia, which offers opportunities for exciting future research.

  18. Central and Eastern Europeans Migrants’ Subjective Quality of Life. A Comparative Study

    2007-11-01

    Full Text Available There is no general agreement among scholars on the consequences oflabor migration on the sending countries. Some argue that the migration would increase the quality of life of the families or communities involved, giving support for democracy and market reforms in these countries, while others share the view that the brain drain and fiscal losses would have long term effects on the sending countries’ development. This paper takes another approach, focusing on the migrant persons’ subjective quality of life.Using data issued in the first two rounds of the European Social Survey (2002/2003, 2004/2005, the Eastern European immigrants’ satisfaction with their lives as a whole and with the social and political environment is measured. They report lower satisfaction with life as a whole, but higher satisfaction with the societal conditions than the natives and other kind of immigrants. Explanation lies in the different sources of these evaluations:when evaluating their overall satisfaction, the immigrants rely on their experiences in their receiving countries, while when evaluating the societal conditions they compare these to those from the sending countries. The fact that they show higher levels of satisfaction with the societal conditions than the other immigrants also supports this hypothesis, because the former are more recent and less accommodated to the receiving society than the latter.

    There are several competing hypotheses for the origin of loess in Europe but quantitative evidence is still rare. Here, Sr-Nd isotopic and bulk elemental composition of loess from Marine Isotope Stages 2 and 3 from three study regions in Central Europe - Nussloch (Germany), Grub (Austria) and Tokaj (Hungary) - are analyzed. This study aims at examining differences and similarities of loess deposits throughout Europe, correlating loess with potential source rocks from major mountain ranges and comparing loess with floodplain sediments from main rivers as integrated samples of the drainage areas. The results show that European loess deposits are largely uniform and that sediment sources have been rather stable in the Southern and Eastern parts of Central Europe and more variable in West Central Europe. However, the methods used are not sufficient to unequivocally confirm and reject potential sediment sources but, in combination, help to identify the most likely sediment origins. While a direct correlation of loess and potential source rocks is dif- ficult, the comparison with floodplain sediments is most promising and confirms previous hypotheses. Loess from Tokaj and Grub is most likely a mix of material transported by the Danube River and sediments from the surrounding mountains. Rhine River sediments are probably the main source of loess at Nussloch.

  20. Latest Permian to Middle Triassic cyclo-magnetostratigraphy from the Central European Basin, Germany: Implications for the geomagnetic polarity timescale

    Science.gov (United States)

    Szurlies, Michael

    2007-09-01

    In Central Germany, the about 1 km thick mainly clastic Germanic Lower Triassic (Buntsandstein) consists of about 60 sedimentary cycles, which are considered to reflect variability in precipitation within the epicontinental Central European Basin, most probably due to solar-induced short eccentricity cycles. They provide a high-resolution cyclostratigraphic framework that constitutes the base for creating a composite geomagnetic polarity record, in which this paper presents a Middle Buntsandstein to lowermost Muschelkalk magnetostratigraphy obtained from 6 outcrops and 2 wells where a total of 471 samples was collected. Combined with recently established records, a well-documented magnetostratigraphy for the upper Zechstein to lowermost Muschelkalk (latest Permian to Middle Triassic) of Central Germany has been constructed, encompassing an overall stratigraphic thickness of about 1.3 km and 22 magnetozones derived from about 2050 paleomagnetic samples. Along with available biostratigraphy, this multi-disciplinary study facilitates detailed links to the marine realm, in order to directly refer biostratigraphically calibrated Triassic stage boundaries as well as radioisotopic ages to the Buntsandstein cyclostratigraphy and, conversely, to contribute to calibrating the geologic timescale.

    Full Text Available The objective of the study is to point out, what kind of measurement methodologies and factor groups are used to determinate the depth of the spatial integration in the national and international scientific literature. Integration means in this sense the interconnection of several (spatial units (Kulcsár-Rostás, 1989; Kovács, 2001; Kiss, 2005. One of the most widely interpreted types of the integration is the economic integration, which can be applied to enterprises and spatial units as well. This study focuses on the last one and examines it at three territorial levels, distinguishing global, supranational (among national states and subnational levels. The possible measurement methods are significantly determined by the spatial levels. The paper makes some suggestions for the possible measurement method in Cenrtral-European context.

  7. Labour Market Trends and Problems in the EU’s Central and Eastern European Member States: Is Flexicurity the Answer?

    Directory of Open Access Journals (Sweden)

    Lothar Funk

    2009-12-01

    Full Text Available Throughout the 1990s, international organisations, such as the International Monetary Fund mainly based their policy proposals for transition economies and the high unemployment, low growth countries in Western Europe, on economic “orthodoxy”. This approach predominantly followed neoclassical economics in which market liberal solutions predominate. These suggestions were controversial; the early results of these policies appeared to be disappointing. Policymakers sought alternative reform proposals and the idea of “flexicurity” has gradually emerged to the political buzzword. Flexicurity combines flexibility with security and suggests that rather generous unemployment benefits and spending on active labour market policies can be aligned with a flexible, employment-friendly labour market. Originating in Denmark, the European Commission and the International Labour Organisation have promoted flexicurity more or less independent of specific single country cases, and based their approach on more abstract, generalised relationships between flexibility and security. These bodies argue for an alternative policy to pure orthodox deregulation and liberalisation for the member states of the European Union (EU and the former transition economies that joined the EU since 2004. After a review of common labour market-related characteristics and problems of the EU’s central and eastern European members, the article summarises and critically evaluates the main elements of flexicurity suggestions. It further compares them to the relevant policy proposals based primarily on more orthodox economic analysis. The analysis shows that several preconditions for a successful flexicurity strategy are still lacking across the new member states. Moreover, the article demonstrates that current proposals by the critics of a single-minded flexicurity approach by no means always disregard potentially positive effects of improving the supposed trade-offs between

    Bullous pemphigoid (BP) is an autoimmune blistering dermatosis of the elderly mediated by IgG and IgE antibodies to skin hemidesmosomal proteins, BP180 and/or BP230, that occur physiologically also in neuronal tissue. It was reported that BP is associated with neurodegenerative diseases (ND). We performed a retrospective study in a setting of a Central European university dermatology department on prevalence of ND in 94 BP patients. 26 out of 94 BP patients had at least one ND. ND included: Parkinson's disease, dementia, stroke, hear loss, tinnitus, blindness, vertigo, neurosyphilis, systemic sclerosis, and epilepsy. Since population aging is conceivably responsible for the rising number of BP cases as a result of immunosenescence-related phenomena, the plausible BP-specific immunopathogenetic relationship between BP and ND deserves to be further experimentally explored.

    Microseismic monitoring of active fault allows one to quickly assess the seismicity of the study area. In platform conditions it requires more time to accumulate of representative data of occurrence of seismic endogenous events. The graphics repeatability, based on data from microseismic monitoring, correlate well with the dependence obtained during long-term regional observations. The focal parameters are assessed for sources of weak seismicity of the central part of East-European platform with the help of small-aperture array. Sensor bandwidth limitations can lead to underestimation of radiated seismic energy due to losses in high-frequency part of signal. Seismometers with enhance amplitude-frequency response in high-frequency part of the spectrum allow avoiding this instrumental problem. This provides records seismic oscillations from events with Mw ~ -2 - 1 and more correct estimation of seismic source parameters.

    Full Text Available The purpose of our paper is to analyze the impact of the recent crisis on the oil and electricity demand and the energy intensity of different Central and Eastern European countries, namely the Czech Republic, Hungary, Poland and Slovakia. Furthermore, we would like to reveal whether there is a lag in the adjustment of energy consumption. In analyzing energy intensity, we use motor gasoline, diesel oil and electricity consumption data and ignore coal and natural gas data. By so doing, we avoid failures arising from changing coal/gas consumption due to changing weather conditions. Our results show that the crisis did impact energy consumption and reveal that the improvement of energy intensity halted in 2009, implying that the economic players did not immediately adjust their energy consumption according to their economic activity. The gasoline and diesel intensity, however, deteriorated (increased only in the Czech Republic and in Hungary. In Slovakia and Poland there were no significant changes.

    The G-24 Training Working Group visited the Central and Eastern European Countries (CEESs), Russia and Ukraine in the course of 1993/94, in order to define priorities for further financial support by the Donor Countries. As a result, it appeared that Nuclear Training needed strong improvements since it is mainly based on OJT (On the Job Training), not SAT (Systematic Approach to Training) oriented and relying essentially on the line supervisor of the trainee. Recommendations were provided to support a SAT based approach development and to provide adequate equipment. In view of the importance of OJT in the training courses, and that probably for some more years, a specific effort should be made in better defining the goals and objectives of the OJT and its coherent integration in the overall training system. In addition, the OJT ''instructors'' have to be trained in the specific teaching skills required to successfully run OJT. (author). 3 figs

    Full Text Available The study has analyzed the relationship between youth unemployment and economic growth, in the context of Okun law, by using new generation panel data analysis and cointegration tests. In this study, 18 Central and Eastern European country have been selected as subject matter whose youth unemployment rate is above the EU-28 average (25 % for the period 2006-2012. The results show that, if youth unemployment is quite severe; even an exclusive economic growth will not be enough to reduce the youth unemployment rate in the country. It is recommended that the global and country-specific policies which are effective, result-driven on youth (Un employment and labour market issues, should be developed. This study is expected to make a significant contribution to the literature on unemployment and social conflict.

    2016-12-01

    Full Text Available Fire is an important structuring force for grassland ecosystems. Despite increased incidents of fire in European steppes, their impact on arthropod communities is still poorly studied. We assessed short-term changes in cursorial beetle and spider assemblages after a summer fire in the meadow steppe in Central European Russia. The responses of spider and beetle assemblages to the fire event were different. In the first post-fire year, the same beetle species dominated burnt and unburnt plots, the alpha-diversity of beetle assemblages was similar, and there were no pronounced changes in the proportions of trophic groups. Beetle species richness and activity density increased in the second post-fire year, while that of the spiders decreased. The spider alpha-diversity was lowest in the first post-fire year, and the main dominants were pioneer species. In the second year, the differences in spider species composition and activity density diminished. The main conclusion of our study is that the large-scale intensive summer fire caused no profound changes in cursorial beetle and spider assemblages of this steppe plot. Mitigation of the fire effect is explained by the small plot area, its location at the edge of the fire site and the presence of adjacent undisturbed habitats with herbaceous vegetation.

  15. Energy consumption, human well-being and economic development in central and eastern European nations: A cautionary tale of sustainability

    International Nuclear Information System (INIS)

    Sustainability is fundamentally a challenge of tradeoffs. In order to improve human well-being through economic development we consume nonrenewable energy and other natural resources, relying on a broad range of ecosystem services. Enhancing sustainability requires reducing the “energy intensity of human well-being (EIWB)”: the amount of energy used per unit of human well-being. In this study we employ longitudinal analysis techniques to assess the temporally dynamic relationship between EIWB and economic development for a sample of 12 Central and Eastern European (CEE) nations for the 1992 to 2010 period. These are nations that have recently transitioned, which is still an ongoing process, from socialist command economies to market demand economies. During this ongoing transition, many of them have experienced declines in energy intensity, coupled with increased energy efficiency, while human well-being has improved considerably. The results of the analysis indicate that the relationship between EIWB and economic growth in CEE nations is complex and has changed dramatically through time. Of particular importance, the later years of the study exhibit an increasingly sustainable relationship between EIWB and economic development. The findings point to future possibilities for relatively more harmonious relationships between development, human well-being, and the natural environment. - Highlights: • We analyze the energy intensity of well-being in Central and Eastern European nations. • The effect of economic development is time-dynamic. • Other factors influence the energy intensity of well-being. • The results highlight possibilities for enhanced sustainability policies

    Developing a tissue bank database has become more than just logically arranging data in tables combined with a search engine. Current demand for high quality samples and data, and the ever-changing legal and ethical regulations mean that the application must reflect TuBaFrost rules and protocols for the collection, exchange and use of tissue. To ensure continuation and extension of the TuBaFrost European tissue bank, the custodianship of the samples, and hence the decision over whether to issue samples to requestors, remains with the local collecting centre. The database application described in this article has been developed to facilitate this open structure virtual tissue bank model serving a large group. It encompasses many key tasks, without the requirement for personnel, hence minimising operational costs. The Internet-accessible database application enables search, selection and request submission for requestors, whereas collectors can upload and edit their collection. Communication between requestor and involved collectors is started with automatically generated e-mails. PMID:17029787

    Eastern European and Central Asian countries are undergoing rapid socioeconomic and political reforms. Many old industrial facilities are either abandoned, or use outdated technologies that severely impact the environment. Emerging industries have less regulation than in developed countries and environmental and occupational problems seem to be increasing. Under a US National Institutes of Health pilot grant, we developed an interdisciplinary One Health research network in Southeastern Europe and West-Central Asia to identify environmental and occupational problems. From 2012 to 2014, this GeoHealth Hub engaged 11 academic centers and 16 public health institutions in eight different countries: Albania, Armenia, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Romania, and the United States with a goal of strengthening environmental and occupational research and training capacities. Employing face-to-face interviews and large group meetings, we conducted an evidenced-based needs and opportunities assessment focused on aquatic health, food safety, and zoonotic diseases. Comprehensive reviews of the published literature yielded priority research areas for each of the seven GeoHealth Hub countries including heavy metal and pesticide contamination, tick-borne diseases, rabies, brucellosis, and inadequate public health surveillance.

    2015-11-01

    Full Text Available The decision of the Swiss National Bank of giving up the fixed rate of 1,2 Euro/CHF on the 15th of January 2015, a rate established at its admission to the Monetary Economic Union, had consequences on Central and Eastern European countries because a great part of the credits granted were in Swiss francs. In all these countries, the national currencies depreciated and the financial market rates were reduced. Regional banks started to face difficulties regarding the management of the situation and were under the necessity of finding solutions to avoid the risk of not recovering the granted credits. The issue of the Swiss franc appreciation was treated differently by the analysed countries and took into consideration the particularities characteristic to the credits granted in this currency. The present paper aims at emphasising the impact of the Swiss franc appreciation on the Romanian banking system but also the approach of other countries in Central and Eastern Europe in this respect.

  1. Characterization of homeobox genes reveals sophisticated regionalization of the central nervous system in the European cuttlefish Sepia officinalis.

    Directory of Open Access Journals (Sweden)

    Laura Focareta

    Full Text Available Cephalopod mollusks possess a number of anatomical traits that often parallel vertebrates in morphological complexity, including a centralized nervous system with sophisticated cognitive functionality. Very little is known about the genetic mechanisms underlying patterning of the cephalopod embryo to arrive at this anatomical structure. Homeodomain (HD genes are transcription factors that regulate transcription of downstream genes through DNA binding, and as such are integral parts of gene regulatory networks controlling the specification and patterning of body parts across lineages. We have used a degenerate primer strategy to isolate homeobox genes active during late-organogenesis from the European cuttlefish Sepia officinalis. With this approach we have isolated fourteen HD gene fragments and examine the expression profiles of five of these genes during late stage (E24-28 embryonic development (Sof-Gbx, Sof-Hox3, Sof-Arx, Sof-Lhx3/4, Sof-Vsx. All five genes are expressed within the developing central nervous system in spatially restricted and largely non-overlapping domains. Our data provide a first glimpse into the diversity of HD genes in one of the largest, yet least studied, metazoan clades and illustrate how HD gene expression patterns reflect the functional partitioning of the cephalopod brain.

The study consisted of 234 patients with breast carcinoma, admitted to the African Oncology Institute in Sabratha, Libya, during the years 2002-2006. The pathological features were collected from pathology reports, patient histories from hospital files and the Sabratha Cancer Registry. The demographic differences between the Libyan, Nigerian and Finnish populations were prominent. The mean age of breast cancer patients in Libya was 46 years which was almost identical to that of Nigeria, but much lower than that of Finland. The Libyan breast cancer incidence was evaluated as 18.8 per 100,000 female individuals. This incidence was markedly higher in Finland, but was also high in Nigeria. Libyan and Nigerian breast cancer is predominantly of premenopausal type and exhibits unfavorable characteristics such as high histological grade and stage, large tumor size and frequent lymph node metastases. However, the histological types and histopathological risk features show similar importance regarding survival as European breast cancer cases. Survival in Libya ranks between the rates of survival in Nigeria (lowest) and Finland (highest). In conclusion, in Libya and other African countries, premenopausal breast cancer is more common than postmenopausal breast cancer. However, the opposite is true for Europe. Population differences may be involved, as suggested by the known variation, in the distribution of genetic markers in these populations. Different types of environmental impacts, however, cannot be excluded.

    European deciduous oaks are closely related and are known for their strong emission of volatile isoprenoids. They are chemo-taxonomically diverse, but hybridise frequently. Four-year-old oak seedlings growing together in a model ecosystem facility under near-natural conditions were studied. The leaves were morphologically classified in the three oak species Quercus robur, Q. pubescens and Q. petraea (with four provenances each) and further investigated by a molecular-genetic approach. Q. robur was morphologically and genetically clearly different from Q. pubescens and Q. petraea, whereas Q. pubescens and Q. petraea individuals used in this study were morphologically and genetically more similar. There was a minor impact of among and within species variability on isoprene synthesis, isoprene emission and photosynthesis. Isoprene emission rates normalised to 25 °C leaf temperature ranged from 5.78 to 10.66 nmol m(-2)  s(-1) , whereas photosynthesis ranged from 12.8 to 17.6 μmol m(-2)  s(-1) . On cloudy days, among the provenances of each species, only net photosynthesis of the Q. robur provenance Hünenberg was reduced and isoprene synthase activity of the Q. pubescens provenance Promotogno increased. On sunny days, photosynthesis did not differ among the provenances. Over all provenances, gas exchange on cloudy days did not differ significantly from sunny days. In the combined data of cloudy and sunny days, no differences between the studied provenances and oak species were detected in isoprene emission and photosynthesis. Thus, isoprene emission and photosynthesis rates were remarkably stable among oak species and provenances. The results indicate that taxonomic differences in the studied oak species are not reflected in isoprene emission and photosynthesis, probably because of the high plasticity of gene expression resulting in high phenotypic flexibility.

    Large scale oscillations-phenomena such as El Niño-Southern Oscillation (ENSO) and North Atlantic Oscillation (NAO) influence the climate and hydrological variables (temperature, precipitation, streamflow) in many areas around the globe. Here we review previous studies examining links between such phenomena and streamflow in Central Europe. The selected area under examination is the region covered by 9 countries: Germany, Poland, Switzerland, Lichtenstein, Austria, the Czech Republic, Slovakia, Hungary and Slovenia. The study takes into consideration only measured and not proxy data. Mean, low and high flows are examined separately in order to improve the understanding on the possible different influences of the climatic phenomena on different streamflow characteristics. Previous results form a consistent pattern that suggests causal relationships but only for certain indices and seasons. Most promising results concern the winter NAO index which seems to affect winter and spring streamflow in Central Europe and synoptic circulation patterns that have been linked to streamflow in the area throughout the year. Based on the findings of the review, we examine further the relations between NAO, synoptic circulation patterns and streamflow in the winter and spring season. In our analysis we examine 68 streamflow stations in Germany all covering the period 1932 to 2005. The investigation focuses on the interplay between NAO and synoptic patterns and on the effects of the climatic indices on the amplitude, spatial coherence and distributions of streamflow data. The preliminary results suggest that NAO weakly influences streamflow in both seasons and that a combined analysis with other climatic parameters may clarify possible existing links.

  5. Rewriting the Central European Early Bronze Age Chronology: Evidence from Large-Scale Radiocarbon Dating.

    Philipp W Stockhammer

    Full Text Available The transition from the Neolithic to the Early Bronze Age in Central Europe has often been considered as a supra-regional uniform process, which led to the growing mastery of the new bronze technology. Since the 1920s, archaeologists have divided the Early Bronze Age into two chronological phases (Bronze A1 and A2, which were also seen as stages of technical progress. On the basis of the early radiocarbon dates from the cemetery of Singen, southern Germany, the beginning of the Early Bronze Age in Central Europe was originally dated around 2300/2200 BC and the transition to more complex casting techniques (i.e., Bronze A2 around 2000 BC. On the basis of 140 newly radiocarbon dated human remains from Final Neolithic, Early and Middle Bronze Age cemeteries south of Augsburg (Bavaria and a re-dating of ten graves from the cemetery of Singen, we propose a significantly different dating range, which forces us to re-think the traditional relative and absolute chronologies as well as the narrative of technical development. We are now able to date the beginning of the Early Bronze Age to around 2150 BC and its end to around 1700 BC. Moreover, there is no transition between Bronze (Bz A1 and Bronze (Bz A2, but a complete overlap between the type objects of the two phases from 1900-1700 BC. We thus present a revised chronology of the assumed diagnostic type objects of the Early Bronze Age and recommend a radiocarbon-based view on the development of the material culture. Finally, we propose that the traditional phases Bz A1 and Bz A2 do not represent a chronological sequence, but regionally different social phenomena connected to the willingness of local actors to appropriate the new bronze technology.

    Full Text Available Abstract Background The European corn borer (ECB, Ostrinia nubilalis, is a textbook example of pheromone polymorphism. Males of the two strains (Z and E prefer opposite ratios of the two pheromone components, Z11- and E11-tetradecenyl acetate, with a sex-linked factor underlying this difference in preference. The male antennal lobes of the two strains contain a pheromone sensitive macroglomerular complex (MGC that is identical in morphology, but reversed in functional topology. However, hybrids prefer intermediate ratios. How a topological arrangement of two glomeruli can accommodate for an intermediate preference was unclear. Therefore we studied the neurophysiology of hybrids and paternal backcrosses to see which factors correlated with male behavior. Results Projection neuron (PN recordings and stainings in hybrids and backcrosses show a dominance of the E-type MGC topology, notwithstanding their intermediate preference. Apparently, the topological arrangement of glomeruli does not directly dictate preference. However, two other factors did correlated very well with preference. First, volumetric measurements of MGC glomeruli demonstrate that, whereas in the parental strains the medial MGC glomerulus is more than 2 times larger than the lateral, in hybrids they are intermediate between the parents, i.e. equally sized. Paternal backcrosses showed that the volume ratio is sex-linked and co-dominant. Second, we measured the summed potential difference of the antennae in response to pheromone stimulation using electroantennogram recordings (EAG. Z-strain antennae responded 2.5 times stronger to Z11 than to E11-14:OAc, whereas in E-strain antennae the ratio was approximately equal. Hybrid responses were intermediate to the parents, and also here the antennal response of the paternal backcrosses followed a pattern similar to the behavioral phenotype. We found no differences in frequency and types of projection and local interneurons encountered

    Parasitological examination of three passerine bird species: the Red-backed Shrike Lanius collurio, Eurasian Golden Oriole Oriolus oriolus and Yellow Wagtail Motacilla flava, revealed the presence of the nematodes Acuaria subula, Diplotriaena ozouxi, Viguiera euryoptera and Microtetrameres inermis. All the birds were obtained in the spring (April-May); the nematodes found were mature, which indicates infection in the hosts' wintering grounds. The gizzard worm Acuaria subula is a new record from Motacilla flava in Europe. Viguiera euryoptera and Diplotriaena ozouxi are new to the Polish fauna. PMID:24881284

    Full Text Available Because of dynamic processes of creative economy development and resistance to the crisis of modern creative industries which occurs mainly in metropolitan areas, the interest in understanding these local processes as a factor of bringing international trade competitiveness and providing convergence among the countries where those metropolises are situated is of great value. The EU, and Central and East Europe (CEE in particular, is not an exception. This paper reveals the most productive creative industries in the EU; fins out the impact of metropolises’ creative activities development on countries’ international specialization. Perspective products’ and geographic patterns relating creative products’ international specialization for CEE countries, especially for those which have recently signed association agreements with the EU (Moldova, Ukraine, and Georgia as an important East Neighbour for the EU are grounded. Using inter- and intra-trading estimations, the positioning of CEE countries in the EU 28(+3 international specialization pattern is indicated. The product specialization of metropolises in CEE countries which may (or may not contribute to further internationalization of creative industries in these countries has been revealed in the article.

    2016-04-01

    Despite the steady advances in numerical modelling, the current generation of climate simulations still struggles to reliably reproduce some of the processes in the climate system and their effects. Aside from the long-term variations, related to the responses to anthropogenic and natural forcings, a great deal of attention is also being devoted to the ability of the climate models to mimic the multidecadal variability observed in the climatic records, including the possible imprints of phenomena such as Atlantic Multidecadal Oscillation or Pacific Decadal Oscillation. In this presentation, we deliver some of our findings resulting from an analysis of observed and simulated temperature variability in central Europe - a region with long history of climatic measurements, with some of the records extending back to (or even beyond) the 19th century. Comparison of the measured temperature data to multiple historical runs of the CNRM-CM5 global climate model is performed, over the 19th and 20th centuries. For the period since 1850, an analysis is also carried out for temperature series originating from various simulations within the Coupled Model Intercomparison Project Phase 5 (CMIP5). We show that while many of the studied models exhibit relatively good skill in capturing the basic statistical characteristics of regional temperature, their representation of long-term trends and multidecadal variability in the temperature series often differs substantially from the observations.

    Patient charges for physician services are implemented in high-income countries and often are considered in the Central and Eastern Europe (CEE). However, there is no evidence on the potential consumption effects of service charges in these countries. This study provides evidence on the potential impact of patient charges on the consumption of specialized physician services in six CEE countries: Bulgaria, Hungary, Lithuania, Poland, Romania, and Ukraine. We apply a semi-parametric survival analysis to stated willingness and ability to pay (WATP) in order to identify potential demand pools and their price, income and age semi-elasticity. Data are collected through a survey held in 2010 among representative samples of about 1000 respondents in each country. Our results suggest that median WATP in the studied countries is comparable to the cost of the services. The obtained demand pools appear to be theoretically valid and externally consistent. They provide information on the shares of population that would be WATP certain fee levels, and their heterogeneity across socio-demographic groups gives an idea about the population groups that will need to be exempted.

    2013-11-01

    We performed detrended correspondence analysis (DCA) ordination to compare seven successional seres running in stone quarries, coal mining spoil heaps, sand and gravel pits, and extracted peatlands in the Czech Republic in central Europe. In total, we obtained 1,187 vegetation samples containing 705 species. These represent various successional stages aged from 1 to 100 years. The successional seres studied were more similar in their species composition in the initial stages, in which synathropic species prevailed, than in later successional stages. This vegetation differentiation was determined especially by local moisture conditions. In most cases, succession led to a woodland, which usually established after approximately 20 years. In very dry or wet places, by contrast, where woody species were limited, often highly valuable, open vegetation developed. Except in the peatlands, the total number of species and the number of target species increased during succession. Participation of invasive aliens was mostly unimportant. Spontaneous vegetation succession generally appears to be an ecologically suitable and cheap way of ecosystem restoration of heavily disturbed sites. It should, therefore, be preferred over technical reclamation. PMID:23436061

  16. Central obesity and risk for type 2 diabetes in Maori, Pacific and European young men in New Zealand

    International Nuclear Information System (INIS)

    Thirty healthy male volunteers between the ages of 18 and 27 and of a wide range of fatness were recruited for this study. Equal numbers (10) self identified as belonging to each of the Maori Pacific and European ethnic groups. Originally it was intended that 90 men(30 in each group) should be measured but the cost and availability of the doubly-labelled water prevented this. Specific measurements undertaken included resting metabolic rate by indirect calorimetry, total energy expenditure over 14 days by the doubly-labelled water technique; total and regional body fat from dual-energy x-ray absorptiometry; anthropometry (body mass index, skinfold thicknesses and girths); fat and carbohydrate utilisation from respiratory quotients and from carbon-13 analysis of expired breath; and dietary intake of macronutrients. Glucose tolerance, insulin, thyroid hormone, leptin and blood lipid determinations were also performed. The groups did not differ significantly in BMI, height body mass or fat mass - but the European group had significantly lower subscapular to triceps skinfolds and fat free mass than the Maori and Pacific group. Resting metabolic rate adjusted for fat mass and fat free mass was not different among the groups. Carbon-13 in expired breath was positively correlated to the subscapular to triceps skinfold ratio and insulin. Reported intake of dietary fibre was negatively related to blood lipids and subscapular to triceps skinfold ratio. Central obesity showed strong associations with biochemical measures of Type 2 diabetes risk These findings emphasise the relationships between body composition and fat distribution with risk of diabetes independent of ethnicity.

    The FP7 project "Climate Information Portal for Copernicus" (CLIPC) is developing a demonstration portal for the Copernicus Climate Change Service (C3S). This project is one of a suite of FP7 research activities which are administratively independent of Copernicus, focussed on creating the technical and scientific building blocks needed for the service. It is to be expected that at EGU 2015 there will be many presentations describing portals delivering new and innovative ranges of services. It would be unwise to seek to replace all this creative activity with a single portal -- instead CLIPC is designing a portal to make distributed resources more accessible through flexible discovery systems. CLIPC needs to deliver more than a directory of resources: resources need to be presented in common protocols so that users can access multiple datasets. More information about the project objectives is available at www.clipc.eu. The gulf between the climate science communities and the end user communities is a central challenge being addressed in the project. It is important to understand that there is significant diversity and multiple communication barriers within these two sets of communities as well as between them. The CLIPC services must presentation will provide a review of progress towards this ambitious goal, through a discussion of user requirements activities, an overview of the proposed architecture, work on assessing and adjusting model biasses, and a discussion of the climate impact indicators which will be provided through the portal. When looking at the usability of data for the various users, CLIPC will implement a set of services functioning as a "knowledge base" supplying information to users about the data, including definitions of terminology used, quality of datasets, versioning, and user annotations.

    Full Text Available A strong windstorm in November 2004 resulted in a huge blown-down spruce forest area in the southern part of the Tatra National Park in the Western Carpathians in Slovakia, Central Europe. The aim of this work is to study the vegetation composition of spruce forest at differently managed sites four years after this disturbance. Four study areas were selected for this purpose: (i an area where the fallen trees were extracted and new seedlings were planted; (ii an area, which was hit by a forest fire after the extraction; (iii an area where no active management was applied; (iv a reference forest unaffected by such disturbance. A total of 100 plots were selected, 25 of each area type. The result of DCA and CCA analyses consistently indicated that after this short period the non-extracted and extracted areas are currently most similar to the reference forest area, while the fire affected area differed. A one-way ANOVA comparing species cover for the different plot sizes indicated some significant differences between the extracted and non-extracted plots. The abundance of certain species commonly occurring in spruce forests, such as Dyopteris carthusiana agg., Vaccinium myrtillus and Avenella flexuosa, correlated weli with the non-extracted plots, compared to the extracted plots. Coverage of these species was lowest on burned plots. The lowest Shannon-Wiener’s diversity values were recorded in burned plots. This was most likely a consequence of mono-dominant competitive species spread, (mainly Chamerion angustifolium which profited from the altered ecological conditions following the fire. Although some differences were also registered in the Shannon-Wiener diversity index between the remaining research plots, however these were not statistically significant. The most important results of our investigations include the extensive influence of fire disturbance on vegetation. Study revealed that the wind-disturbed area is able to regenerate

  19. Manifestation of Preferential Flow and Nitrate Transport in Central European Soils on Acid Crystalline Rocks

    Large areas of Central Europe are occupied by highlands and peneplains of medium altitudes, built by acid crystalline rocks. The soils overlying them are typically of medium textures. They are neither markedly water- repellent nor greatly swelling and shrinking. These landscapes are characterized by high vulnerability of water bodies, both surface and subsurface. The existing methodologies of vulnerability assessment regard the heavier among these soils as little vulnerable to diffuse pollution, while in reality they may be virtually equally vulnerable, because of the short-circuiting effect of preferential flow and transport. Our experiment site was Valeèov (49° 38' 40" N, 14° 30' 25" E, 461 m a.s.l.) in the Bohemo-Moravian highland, with average annual precipitation 660 mm and average annual air temperature 7.2 ° C. The field trials, starting from 2001, were focused on growing potato under different conditions. Soil moisture content was measured by Theta- probe capacitance sensors, soil water suction by Watermark sensors and tensiometers. Nitrate leaching was monitored by soil solution sampling with ceramic suction cups and zero-tension lysimeters. The hydraulic conductivity of the soil was measured on small cores and by suction and pressure infiltrometers. The following preferential flow manifestations are analyzed and quantified: a) the spatial variability of soil moisture content and suction after rainstorms, b) the spatial and temporal variability of soil's hydraulic conductivity and its dependence on soil moisture content, c) the spatial variability of percolation volumes in parallel lysimeters, d) the variability of nitrate concentrations in the lysimeter leachate, e) the apparent absence of correlation between leachate volumes and leachate concentrations in lysimeters, f) the lower mean and higher variance of leachate concentrations in lysimeters, in comparison with those in suction cups.

    2006-05-01

    Full Text Available The effects of anomalous weather conditions on the sea surface layer over the Central Mediterranean were studied with an eddy resolving regional ocean model by performing a 5-year long simulation from 2000 to 2004. The focus was on surface heat fluxes, temperature and dynamics. The analysis of the time series of the selected variables permitted us to identify and quantify the anomalies of the analysed parameters. In order to separate the part of variability not related to the annual cycle and to locate the anomalies in the time-frequency domain, we performed a wavelet analysis of anomalies time series. We found the strongest anomalous event was the overheating affecting the sea surface in the summer of 2003. This anomaly was strictly related to a strong increase of air temperature, a decrease of both wind stress and upward heat fluxes in all their components. The simulated monthly averages of the sea surface temperature were in a good agreement with the remotely-sensed data, although the ocean regional model tended to underestimate the extreme events. We also found, on the basis of the long-wave period of the observed anomaly, this event was not limited to the few summer months, but it was probably part of a longer signal, which also includes negative perturbations of the involved variables. The atmospheric parameters responsible for the overheating of the sea surface also influenced the regional surface and sub-surface dynamics, especially in the Atlantic Ionian Stream and the African Modified Atlantic Water current, in which flows seem to be deeply modified in that period.

  1. A MACROPRUDENTIAL SUPERVISION MODEL. EMPIRICAL EVIDENCE FROM THE CENTRAL AND EASTERN EUROPEAN BANKING SYSTEM

    2013-07-01

    Full Text Available One of the positive effects of the financial crises is the increasing concern of the supervisors regarding the financial system’s stability. There is a need to strengthen the links between different financial components of the financial system and the macroeconomic environment. Banking systems that have an adequate capitalization and liquidity level may face easier economic and financial shocks. The purpose of this empirical study is to identify the main determinants of the banking system’s stability and soundness in the Central and Eastern Europe countries. We asses the impact of different macroeconomic variables on the quality of capital and liquidity conditions and examine the behaviour of these financial stability indicators, by analyzing a sample of 10 banking systems during 2000-2011. The availability of banking capital signals the banking system’s resiliency to shocks. Capital adequacy ratio is the main indicator used to assess the banking fragility. One of the causes of the 2008-2009 financial crisis was the lack of liquidity in the banking system which led to the collapse of several banking institutions and macroeconomic imbalances. Given the importance of liquidity for the banking system, we propose several models in order to determine the macroeconomic variables that have a significant influence on the liquid reserves to total assets ratio. We found evidence that GDP growth, inflation, domestic credit to private sector, as well as the money and quasi money aggregate indicator have significant impact on the banking stability. The empirical regression confirms the high level of interdependence of the real sector with the financial-banking sector. Also, they prove the necessity for an effective macro prudential supervision at country level which enables the supervisory authorities to have an adequate control over the macro prudential indicators and to take appropriate decisions at the right time.

    Full Text Available Cue-conflict experiments were performed to study the compass calibration of one predominantly diurnal migrant, the dunnock (Prunella modularis, and two species of nocturnal passerine migrants, the sedge warbler (Acrocephalus schoenobaenus, and the European robin (Erithacus rubecula during autumn migration in South Sweden. The birds' orientation was recorded in circular cages under natural clear and simulated overcast skies in the local geomagnetic field, and thereafter the birds were exposed to a cue-conflict situation where the horizontal component of the magnetic field (mN was shifted +90° or −90° at two occasions, one session starting shortly after sunrise and the other ca. 90 min before sunset and lasting for 60 min. The patterns of the degree and angle of skylight polarization were measured by full-sky imaging polarimetry during the cue-conflict exposures and orientation tests. All species showed orientation both under clear and overcast skies that correlated with the expected migratory orientation towards southwest to south. For the European robin the orientation under clear skies was significantly different from that recorded under overcast skies, showing a tendency that the orientation under clear skies was influenced by the position of the Sun at sunset resulting in more westerly orientation. This sun attraction was not observed for the sedge warbler and the dunnock, both orientating south. All species showed similar orientation after the cue-conflict as compared to the preferred orientation recorded before the cue-conflict, with the clearest results in the European robin and thus, the results did not support recalibration of the celestial nor the magnetic compasses as a result of the cue-conflict exposure.

  3. Fruiting Season Length Restricts Global Distribution of Female-Only Parental Care in Frugivorous Passerine Birds

    Food availability is known to influence parental care and mating systems in passerine birds. Altricial chicks make uni-parental care particularly demanding for passerines and parental investment is known to increase with decreasing food availability. We expect this to limit uni-parental passerines to habitats with the most consistent food availability. In passerine birds, species having uni-parental care are primarily female-only parental care (female-only care) and most passerine birds with female-only care are frugivores. We predict that frugivorous passerines with female-only care should be restricted to the most stable habitats characterized by longer fruiting season length. At a global scale, female-only care frugivores were distributed in areas with significantly longer fruiting seasons than non-female-only care frugivores. Female-only care species richness had a stronger spatial relationship with longer fruiting season than non-female-only care species richness. Verifying the lack of a phylogenetic signal driving this pattern, our findings indicate that the geographic distribution of female-only care, a geographically and phylogenetically widespread parental care system, is restricted by an extrinsic factor: fruiting season length. This reinstates the importance of food availability on the evolution and maintenance of parental care systems in passerine birds. PMID:27149262

  4. Passerine bird communities of Iberian dehesas: a review

    Directory of Open Access Journals (Sweden)

    Tellería, J. L.

    2001-01-01

    Full Text Available The Iberian dehesas are a man-made habitat composed of scattered oaks (Quercus spp. and extensive grass cover occupying three million ha in south-western Iberia. This paper compares the structure of the passerine bird communities in this region with other bird assemblages of Iberian woodlands. Although forest bird numbers in the southern half of the Iberian peninsula are decreasing, the dehesas show the highest richness in breeding birds, seemingly as the result of the increased presence of border and open-habitat birds. A low intra-habitat turnover of species was observed in the dehesas, with birds recorded at a sampling point accounting for a high percentage of the total richness of the community. This can be related to the low spatial patchiness of this habitat. In winter, the dehesas continued to maintain many bird species, but showed bird densities similar to other woodlands. This pattern, as well as the scarcity of some common forest passerines during the breeding period, could result from the removal of the shrub layer typical of Mediterranean woodlands.

The WG-friendly scenarios for the present experiment are based on comparison of future vs baseline surface weather series simulated by GCMs from a CMIP3 database. The second part will present results of climate change impact study based on an above methodology applied to Central Europe. The changes in selected climatic (focusing on the extreme precipitation and temperature characteristics) and agroclimatic (including number of days during vegetation season with heat and drought stresses) characteristics will be analysed. In discussing the results, the emphasis will be put on 'added value' of various aspects of above methodology (e.g. inclusion of changes in 'advanced' WG parameters into the climate change scenarios).

    I examined the hypothesis that the clutch size of some altricial birds may be limited by over-crowding of the nestlings in the nest, by comparing data on different species of European passerines. Large-sized birds build, relative to the body, larger nests than small-sized birds, both as regards the inner and the outer nest widths and as regards edge breadth; only inner nestcup depth did not change relatively to body size. Nest size also varied in relation to nesting place. Birds with open nests built off the ground had a rather narrow nestcup, whereas those with a domed nest, or which nest in a cavity, had a wide nestcup. When only open-nesters were compared, birds nesting on, or close to, the ground tended to have a wider nestcup than birds nesting above the ground. Inner nestcup width was correlated with the amount of mosses and lichens used in building the nest; the more of such materials the narrower the nestcup. The three variables: standardised body size, nesting place, and type of nesting material used accounted for 92% of the overall variation observed in inner nestcup width. When controlling for adult body size, clutch size was positively correlated with the size of the nestcup. A multiple regression analysis showed that relative nestcup depth, nest site, and type of nesting materials used, accounted for 64% of the overall variation in clutch size. PMID:23921394

    Full Text Available Abstract Objective: To determine the prevalence of malocclusion and orthodontic treatment need in a large sample of Central Anatolian adolescents and compare them with European-other nations' adolescents. Methods: The sample included 1125 boys and 1204 girls aged between 12 and 16 years with no previous orthodontic treatment history. Occlusal variables examined were molar relationship, overjet, overbite, crowding, midline diastema, posterior crossbite, and scissors bite. The dental health (DHC and aesthetic components (AC of the Index of Orthodontic Treatment Need (IOTN were used as an assessment measure of the need for orthodontic treatment for the total sample. Results: The results indicated a high prevalence of Class I (34.9% and Class II, Division 1 malocclusions (40.0%. Moreover, increased (18% and reduced bites (14.%, and increased (25.1% and reversed overjet (10.% were present in the sample. Conclusion: Using the DHC of the IOTN, the proportion of subjects estimated to have great and very great treatment need (grades 4 and 5 was 28.%. However, only 16.7% of individuals were in need (grades 8-10 of orthodontic treatment according to the AC.

  8. Population Trends of Central European Montane Birds Provide Evidence for Adverse Impacts of Climate Change on High-Altitude Species.

    Full Text Available Climate change is among the most important global threats to biodiversity and mountain areas are supposed to be under especially high pressure. Although recent modelling studies suggest considerable future range contractions of montane species accompanied with increased extinction risk, data allowing to test actual population consequences of the observed climate changes and identifying traits associated to their adverse impacts are very scarce. To fill this knowledge gap, we estimated long-term population trends of montane birds from 1984 to 2011 in a central European mountain range, the Giant Mountains (Krkonoše, where significant warming occurred over this period. We then related the population trends to several species' traits related to the climate change effects. We found that the species breeding in various habitats at higher altitudes had more negative trends than species breeding at lower altitudes. We also found that the species moved upwards as a response to warming climate, and these altitudinal range shifts were associated with more positive population trends at lower altitudes than at higher altitudes. Moreover, long-distance migrants declined more than residents or species migrating for shorter distances. Taken together, these results indicate that the climate change, besides other possible environmental changes, already influences populations of montane birds with particularly adverse impacts on high-altitude species such as water pipit (Anthus spinoletta. It is evident that the alpine species, predicted to undergo serious climatically induced range contractions due to warming climate in the future, already started moving along this trajectory.

  9. Properly pricing country risk: a model for pricing long-term fundamental risk applied to central and eastern European countries

    2010-09-01

    Full Text Available The private sector has used proxies such as sovereign credit ratings, spreads on sovereign bonds and spreads on sovereign credit default swaps (CDS to gauge country risk, even though these measures are pricing the risk of default of government bonds, which is different from the risks facing private participants in cross-border financing. Under normal market conditions, the CDS spreads are a very useful source of information on country risk. However, the recent crisis has shown that the CDS spreads might lead to some underpricing or overpricing of fundamentals in the case of excessively low or excessively high risk aversion. In this paper we develop an alternative measure of country risk that extracts the volatile, short-term market sentiment component from the sover eign CDS spread in order to improve its reliability in periods of market distress. We show that adverse market sentiment was a key driver of the sharp increase in sovereign CDS spreads of central and eastern European (CEE countries during the most severe phase of the crisis. We also show that our measure of country risk sheds some light on the observed stability of cross-border bank flows to CEE banks during the crisis.

    Full Text Available Background and Objectives: Although studied extensively among adults, self-rated health (SRH has not received the same research attention among adolescents. It has been suggested that SRH in adolescents may be a function of adolescents' overall sense of functioning and may reflect psychosocial functioning more so than in adults. The rating of health as poor by adolescents might be a somatic expression of life distress and may be connected with risky behaviors. Therefore, the purpose of this study was to investigate self-rated health (SRH in Central and Eastern European (CEE adolescents and determine its association with psychosocial functioning and other dimensions of adolescent health. Methods: A survey was administered to 3,123 students in 34 secondary schools across CEE which included measures of SRH, psychosocial functioning (loneliness, hopelessness, shyness, perceptions of social status, self-rated happiness, and perception of physical attractiveness, and other dimensions of adolescent health (height/weight, physical activity, eating breakfast, sleep. Results: More girls (19.4 % than boys (11.3 % rated themselves as "not healthy" and this was true in each of the six countries. Significant predictors of SRH in the logistic regression model were gender, country of residence, hopelessness, shyness, subjective social status-society, self-rated happiness, perception of physical attractiveness, vigorous physical activity, eating breakfast, overweight status, and usually get 7-8 hours or more sleep a night. Conclusions: SRH appears to be associated with psychosocial functioning and other dimensions of adolescent health in CEE youth.

    Full Text Available Unexpected fluctuations in exchange rates represent a matter of concern for all businesses nowadays as the volatility in exchange rates impacts businesses’ cash flows, revenues and expenses, and eventually is reflected in the company’s risk-return profile. Companies’ exposures to exchange rate risk have considerably increased in the past decades, given the boost in international operations and the continuous diversification of businesses’ activities at the global level. Despite the attention that businesses display to nominal exchange rates changes, it is the real exchange rate that should be of more concern to corporate managers, since they induce changes at the level of the competitiveness of the business. Our paper comparatively analyzes the exposure to changes in the nominal and real exchanges rates of the local currencies that companies from a number of four Central and Eastern European countries (Romania, Hungary, Czech Republic and Poland and investigates the nature of the relationship between stock market performance and exchange rates in the four countries under consideration. We find limited evidence for contemporaneous and asymmetric exposure to nominal and real exchange rate risk in all four countries, but consistent evidence for three to four months lagged exposure.

    2011-01-01

    Full Text Available A major objective of our research was to survey soil biological activity and organic mattercontent reduction in a Central European oak forest during treatments of various detritus inputs within theSíkfkút DIRT (Detritus Input and Removal Treatments Project. Beside the control, three detritusremoval and two detritus duplication treatments were applied. Our examinations have proven that soilorganic matter content declined relatively fast in detritus removal treatments. The reduction wasespecially remarkable in root detritus removal treatments, where – due to the lack of transpiration – soilswere moister during the whole year than in the other treatments. The higher moisture content, despite ofthe reduction of detritus input, produced an intense soil respiration. This can be explained by the fact thatdecomposing organisms have increased the use of soil organic matter. Detritus input reduction had asignificantly greater effect on soil respiration and organic matter content than detritus input duplicationof the same extent. The latter did not cause any significant change compared to the control.

    欧债危机期间,欧央行为支持融资环境和信贷流动,并弥补利率政策的局限性,除下调主要政策利率外,还多管齐下地采取了大量创新性﹑非常规货币政策措施,短期内对稳定金融市场起到了一定效果。但同时,非常规货币政策导致欧央行资产负债表规模激增,风险敞口不断上升,不过欧央行的风险管理框架确保风险能得到有效控制与缓解。尽管欧央行在欧债危机救助中发挥了重要作用,但由于欧盟框架下的制度设计缺陷导致欧央行缺乏最后贷款人职能,严重影响了危机的救助时机和延缓了欧元区经济的复苏。欧央行危机救助的经验和教训对中国未来可能的危机救助提供了一些启示:一是政府救助要遵守一定的原则,二是中央银行要发挥好最后贷款人的作用,三是中央银行要采取相应风险防范措施,以规避资产风险上升的可能性。%During the European debt crisis, European central bank had taken a lot of innovative and unconventional monetary pol-icy measures besides cutting down main policy rates to support the financing environment and the credit flow and make up the limita-tions of the interest rate policy, which had a certain effect on stabilizing the financial markets in the short term. But at the same time, unconventional monetary policies caused the rise of the scale of the balance sheet of the European central bank and exposure to risks. However, the risk management framework of the European central bank ensured that the risk could be effectively controlled and allevi-ated with ease. Although the European central bank had played an important role in the crisis rescue, but the system design defects un-der the European Union framework lead to that the European central bank takes no responsibility of the lender of last resort, which se-riously affects the crisis rescue opportunity time and postpones the Euro zone’s economic

    Relationships between the soil moisture availability and the atmospheric circulation in Central Europe were analyzed for the period 1881-2005. The analysis was based on the Hess-Brezowsky catalogue of circulation types (CTs), and a series of weekly self-calibrated Palmer Z-index (scZ-index) and Palmer Drought Severity Index (scPDSI) values at seven stations where high-quality daily data has recently become available. The results show that the large-scale droughts during spring months (MAM) were associated with east (E), south (S), and south- east (SE) circulation types, whereas during summer (JJA) and the whole vegetation season, i.e., April-September (VEG), the Central Europe high pressure systems (HM) and east (E) circulation types were conducive to drought. Statistically significant drying trends were noted at a majority of the stations, especially during MAM and JJA, over the whole period for which the scPDSI and scZ-index series were available (1875-2005). Although almost no statistically significant tendencies were found prior to 1940, a significant tendency towards more intense drought was present at all sites after this year. The largest drying trend was noted during the VEG and AMJ seasons. The overall drying trend might be associated with shifts in the frequency of CTs, especially during AMJ. Although the aggregate frequency of occurrence of drought-conducive CTs (i.e. E, S and HM) remained stable at approximately 30% up to the 1940s, a steady increase to the present 55% frequency is observed afterwards. Higher frequencies of S and HM types drove the observed increase of drought-conducive CTs at the expense of N types that are associated with wet conditions. The long-term shifts in the frequency of circulation types conducive to drought explain more than 50% of the long-term variations of both scZ-index and PDSI values over the territory of the Czech Republic, and they are likely to affect whole central European region as well.

    2016-06-01

    Full Text Available The European Central Bank (ECB has received a lot of criticism for its too little, too late performance to ease market pressures during the economic crisis. At the same time, the ECB and the Federal Reserve (FED have managed the new economic realities that have emerged in the international context differently. Despite the criticisms, the European Central Bank is the European Union institution that has assumed more control due to the new model of economic governance of the EU. Why did the Federal Reserve act so nimbly and quickly to calm the markets, while the ECB was so cautious in managing monetary policy? The aim of this paper is to perform a comparative analysis of the management of interest rates and other monetary policy measures undertaken by the Central Bank and the Federal Reserve during the economic crisis, as well as to understand the changes in the context of the ECB and the emergence of its authority within the European Union’s economic governance model since 2011. Thus, in order to carry out a scrupulous exposition, we will also limit the time frame of this study to the 2007-2014 period.

    The relationships of passerines (such as the well-studied zebra finch) with non-passerine birds is one of the great enigmas of avian phylogenetic research, because decades of extensive morphological and molecular studies yielded highly inconsistent results between and within data sets. Here we show the first application of the virtually homoplasy-free retroposon insertions to this controversy. Our study examined ~200,000 retroposon-containing loci from various avian genomes and retrieved 51 markers resolving early bird phylogeny. Among these, we obtained statistically significant evidence that parrots are the closest and falcons the second-closest relatives of passerines, together constituting the Psittacopasserae and the Eufalconimorphae, respectively. Our new and robust phylogenetic framework has substantial implications for the interpretation of various conclusions drawn from passerines as model organisms. This includes insights of relevance to human neuroscience, as vocal learning (that is, birdsong) probably evolved in the psittacopasseran ancestor, >30 million years earlier than previously assumed.

    The essential spatial and temporal variability is mutual feature for most natural and man-changed soils at the Central region of European territory of Russia. The original spatial heterogeneity of forest and forest-steppe soils has been further complicated by a specific land-use history and different-direction soil successions due to environmental changes and human impacts. For demand-driven land-use planning and decision making the quantitative analysis, modeling and functional-ecological interpretation of representative soil cover patterns spatial variability is an important and challenging task that receives increasing attention from scientific society, private companies, governmental and environmental bodies. On basis of long-term different-scale soil mapping, key plot investigation, land quality and land-use evaluation, soil forming and degradation processes modeling, functional-ecological typology of the zonal set of elementary soil cover patterns (ESCP) has been done in representative natural and man transformed ecosystems of the forest, forest-steppe and steppe zones at the Central region of European territory of Russia (ETR). The validation and ranging of the limiting factors of functional quality and ecological state have been made for dominating and most dynamical components of ESCP regional-typological forms - with application of local GIS, traditional regression kriging and correlation tree models. Development, zonal-regional differentiation and verification of the basic set of criteria and algorithms for logically formalized distinguishing of the most "stable" & "hot" areas in soil cover patterns make it possible for quantitative assessment of dominating in them elementary landscape, soil-forming and degradation processes. The received data essentially expand known ranges of the soil forming processes (SFP) rate «in situ». In case of mature forests mutual for them the windthrow impacts and lateral processes make SFPs more active and complex both in

    The Upper Muschelkalk in the Central European Basin (CEB) is a key example of eustatic and climatic controls on inland seas. The late Anisian rapid transgression from Tethyan waters culminated in a large semi-enclosed inland sea stretching across the CEB. Subsequently, the slow but successive retreat in the early Ladinian resulted in a small remnant sea. The pronounced stratal pattern architectures are translated into a framework of 3rd- and 4th-order T-R sequences. The latest Illyrian 3rd-order maximum flooding surface corresponds to maximum abundances of carbonates and marine phytoplankton. An euryhaline marine ecology is indicated by prasinophycean algae dominating over acritarchs and δ18OP values of 18.9-22.4‰ VSMOW corresponding to Tethyan references. During the 3rd-order regressive phase successive freshening up to hyposaline conditions is indicated by up to 3‰ depleted δ18OP values, shifts to more radiogenic 87Sr/86Sr ratios and maximum abundances of terrestrial palynomorphs. Likewise, 4th-order T-R sequences are constrained by commutated stratal pattern architectures, palynofacies and geochemistry. The favourable correlation of middle Triassic 3rd-order sequences of Tethyan and peri-Tethyan basins demonstrate the principle control of circum-Tethyan eustatic cycles. 4th-order sequences are evident and, although not yet correlatable in detail, indicate 106-year scale eustatic cycles which may be attributed to glacioeustatic sea-level changes. The subordinated control of arid to semiarid low latitude and semihumid to humid temperate mid latitude climates affected the Upper Muschelkalk Sea in particular during 4th-order sea-level lowstands. Substantial fresh water input from Scandinavian sources caused temporal stratification leading to stagnant bottom waters and/or sediments as indicated by palynofacies and U/Th and Ni/Co redox indices. The herein reconstructed middle Triassic zonal climates are in agreement to previously published Late Triassic zonal

    In the mid-1990s, researchers began using miniature cameras to videotape activities at cryptic passerine nests in grasslands.In subsequent years, use of these video surveillance systems spread dramatically, leading to major strides in our knowledge of nest predation and nesting ecology of many species.Studies using video nest surveillance have helped overturn or substantiate many long-standing assumptions and have provided insights on a wide range of topics.Using examples from grasslands, we highlight the accumulated knowledge about activities at nests documented with video; we also discuss implications of this knowledge for our understanding of avian ecology.Like all tools, video nest surveillance has potential limitations, and users must take precautions to minimize possible sources of bias in data collection and interpretation.

    The Renicolidae are digenean parasites of piscivorous and molluscivorous birds. Although they exhibit few morphological autapomorphies and are highly variable, the numerous suggested re-classifications within the family have never been supported by any molecular analyses. We address the possible synonymization of species within the Renicola pinguis complex suggested previously by Odening. We provide and analyse sequences of two nuclear (ITS2, 28S rDNA) and two mitochondrial (CO1, ND1) DNA loci of central European species of the Renicolidae, namely Renicola lari, Renicola pinguis and Renicola sternae sp. n., and we also provide first sequences of Renicola sloanei. The combined molecular and comparative morphological analysis confirms the previously questioned validity of the three Renicola spp. of highly similar morphology, which display strict niche separation in terms of host specificity and selectivity. We identify two previously unreported clades within the genus Renicola; however, only one of them is supported by the analysis of adult worms. We also provide comparative measurements of the three examined closely related central European renicolids, and describe the newly proposed tern-specialized species Renicola sternae sp. n., which was previously repeatedly misidentified as Renicola paraquinta. Based on the extensive dataset collected in 1962-2015, we update the host spectrum of Renicolidae parasitizing central European birds (Renicola bretensis, R. lari, Renicola mediovitellata, R. pinguis, Renicola secunda and R. sternae sp. n.) and discuss their host-specific prevalence and intensity of infections.

    2012-12-01

    Full Text Available This paper empirically investigates the impact of the Global financial crisis on the efficiency of four Central and Eastern European emerging unit-linked insurance markets, applying the automatic variance ratio (AVR test of Kim (2009 and variance ratio tests using ranks and signs by Wright (2000 for entire, pre-crisis and crisis periods. This study contributes to the existing literature on efficient market hypothesis with several distinct features: it provides a systematic review of the weak-form market efficiency literature that examines return predictability of the daily ING unit-linked funds prices; also the article aims at monitoring any improvement in the degree of efficiency in time and also examines the relative efficiency of unit-linked insurance markets in pre-crisis and crisis periods. Unit linked insurance are life insurance policies with investment component. In the literature there are few studies investigating the effects of a financial crisis on the potential of predictability and implicitly on the degree of efficiency of financial markets. The occurrence of a market crash or financial crisis is a possible contributing factor of market inefficiency. Most of the studies are focused on the Asian crisis in 1997: Holden et al. (2005 examined the weak-form efficiency of eight emerging Asian stock markets using VR tests before, during and after the Asian crisis; Kim and Shamsuddin (2008 used three different types of multiple VR tests for nine Asian stock markets; the findings reported by Lim et al. (2008 are consistent with those reported by Cheong et al. (2007, in which the highest inefficiency occurs during the crisis period. Todea and Lazar (2010 investigated the effects of the Global crisis on the relative efficiency of ten CEE stock markets, using Generalized Spectral test of Escanciano and Velasco (2006. Wright (2000 proposes the alternative non-parametric variance ratio tests using ranks and signs of return and demonstrates that

    2007-05-01

    Full Text Available The effects of the 2003 European heatwave on the sea surface layer of the Central Mediterranean were studied using a regional 3-D ocean model. The model was used to simulate the period 2000 to 2004 and its performance was validated using remotely-sensed and in situ data. Analysis of the results focused on changes in the Sea Surface Temperature (SST and on changes to the surface and sub-surface current field. This permitted us to identify and quantify the anomalies of atmospheric and sea surface parameters that accompanied the heatwave. The dominant annual cycle in each variable was first removed and a wavelet analysis then used to locate anomalies in the time-frequency domain.

    We found that the excess heating affecting the sea surface in the summer of 2003 was related to a significant increase in air temperature, a decrease in wind stress and reduction of all components of the upward heat flux. The monthly averages of the model SST were found to be in good agreement with remotely-sensed data during the period studied, although the ocean model tended to underestimate extreme events. The spatial distribution of SST anomalies as well as their time-frequency location was similar for both the remotely-sensed and model temperatures. We also found, on the basis of the period of the observed anomaly, that the event was not limited to the few summer months of 2003 but was part of a longer phenomenon. Both the model results and experimental data suggest the anomalous heating mainly affected the top 15 m of ocean and was associated with strong surface stratification and low mixing.

    The skill of the model to reproduce the sub-surface hydrographic features during the heatwave was checked by comparison with temperature and salinity measurements. This showed that the model was generally in good agreement with observations. The model and observations showed that the anomalous warming also modified the currents in the region, most noticeably

    Circular orientation cages have been used for several decades to record the migratory orientation of passerine migrants, and have been central to the investigation of the functional characteristics of the biological compasses used for orientation. The use of these cages offers unique possibilities to study the migratory behaviour of songbirds, but suffers from statistical limitations in evaluating the directions of the activity recorded in the cages. The migratory activity has been reported to vary, including complex multimodal orientation of migratory passerines tested in orientation cages irrespective of species studied. The currently applied circular statistical methods fail to describe orientation responses differing from unimodal and axial distributions. We propose for the first time a modelling procedure enabling the analysis of multimodal distributions at either an individual or a group level. In this paper we compare the results of conventional methods and the recommended modelling approach. Migratory routes may be more complex than a simple migratory direction, and multimodal behaviour in migratory species at the individual and population levels can be advantageous. Individuals may select the expected migratory direction, but may also return to safer sites en route, i.e. sites already known, which provide food and/or shelter in reverse directions. In individual birds, several directions may be expressed in the same test hour. At the species level, multimodal orientation may give an opportunity to expand the range or may refer to differential migration route preferences in different populations of birds. A conflicting experimental situation may also result in a different preferential orientation. In this paper we suggest a statistical solution to deal with these types of variations in orientation preference.

  11. Repeatability of feather mite prevalence and intensity in passerine birds.

    Javier Diaz-Real

    Full Text Available Understanding why host species differ so much in symbiont loads and how this depends on ecological host and symbiont traits is a major issue in the ecology of symbiosis. A first step in this inquiry is to know whether observed differences among host species are species-specific traits or more related with host-symbiont environmental conditions. Here we analysed the repeatability (R of the intensity and the prevalence of feather mites to partition within- and among-host species variance components. We compiled the largest dataset so far available: 119 Paleartic passerine bird species, 75,944 individual birds, ca. 1.8 million mites, seven countries, 23 study years. Several analyses and approaches were made to estimate R and adjusted repeatability (R(adj after controlling for potential confounding factors (breeding period, weather, habitat, spatial autocorrelation and researcher identity. The prevalence of feather mites was moderately repeatable (R = 0.26-0.53; R(adj = 0.32-0.57; smaller values were found for intensity (R = 0.19-0.30; R(adj = 0.18-0.30. These moderate repeatabilities show that prevalence and intensity of feather mites differ among species, but also that the high variation within species leads to considerable overlap among bird species. Differences in the prevalence and intensity of feather mites within bird species were small among habitats, suggesting that local factors are playing a secondary role. However, effects of local climatic conditions were partially observed for intensity.

    Species ecomorphological characteristics are the evolutionary results of selective pressures that have enabled individuals of a given species to survive and reproduce. Closely related species co-occurring in homogeneous environments should be morphologically distinct to partition limited resources, so as to minimize interspecific competition. From 1983 to 2012, we studied the ecomorphological characteristics of nine passerine species in alpine meadow. Results showed six ecomorphological characteristics of the nine species were significantly different. Approximately, 92.0% of samples were correctly classified and the correct rates ranged from 84.5% to 100.0%, except for the Oriental Skylark (Eremophila alpestris), which was 79.2%. Accordingly, the nine species were divided into five guilds based on their characteristics. Results indicated that the niches of all species were divergent, and the ecomorphological characteristics of the specific species in each guild were related to their habitats and foraging behaviors. These results also explained the possible mechanisms of different species coexistence in alpine meadow. PMID:23775990

  15. Nest predation and reproductive traits in small passerines: a comparative approach

    Science.gov (United States)

    Yanes, Miguel; Suárez, Francisco

    Nest predation can be a decisive factor in the evolution of bird reproduction strategies. This paper compares several reproductive traits in small passerines on the Iberian Peninsula (n=31) with the probability of daily nest survival from predation. We consider the phylogenetic relationships between species by means of an analysis according to three models of evolutionary change: Brownian, punctuational and GRAFEN'S arbitrary. In this comparative evolutionary scenario, clutch size, egg volume and incubation period appear not to change in relation to nest predation, while the nestling phase duration is a positively-related parameter to daily nest survival from predation. These results are consistent for all models of evolutionary change. Thus, from the perspective of nest predation, the nestling period is the most important evolutionary parameter in small passerines. A hypothetical influence of nest predation on passerine clutch and egg size should only be regarded as an indirect factor, linked to the relationship between these parameters and the duration of the nestling period.

  16. Leptin affects life history decisions in a passerine bird: a field experiment.

    Directory of Open Access Journals (Sweden)

    Mare Lõhmus

    Full Text Available BACKGROUND: Organisms face trade-offs regarding their life-history strategies, such as decisions of single or multiple broods within a year. In passerines displaying facultative multiple breeding, the probability of laying a second clutch is influenced by several life-history factors. However, information about the mechanistic background of these trade-offs is largely lacking. Leptin is a protein hormone produced by white fat cells, and acts as a signal between peripheral energy depots and the central nervous system. In addition, leptin affects cells at all levels of the reproductive axis and plays a critical role in regulating the allocation of metabolic energy to reproduction. As such, it is possible that leptin levels influence the decision of whether or not to invest time and energy into a second clutch. Accordingly, we expect a treatment with exogenous leptin to result in an increased number of second broods. METHODOLOGY/PRINCIPAL FINDINGS: At a later stage during the first brood, female great tits were treated either with long-term leptin-filled cholesterol pellets (the experimental birds or with pellets containing only cholesterol (the control birds. We found that leptin-treated females were significantly more likely to have a second brood and that the earlier females were more likely to lay a second clutch than the late females. CONCLUSIONS/SIGNIFICANCE: As both timing of first brood and treatment with leptin were important in the decision of having multiple broods, the trade-offs involved in the breeding strategy most likely depend on multiple factors. Presumably leptin has evolved as a signal of energy supply status to regulate the release of reproductive hormones so that reproduction is coordinated with periods of sufficient nutrients. This study investigated the role of leptin as a mediator between energy resources and reproductive output, providing a fundamentally new insight into how trade-offs work on a functional basis.

  17. Plasma carotenoid levels in passerines are related to infection by (some parasites

    Full Text Available Plumage coloration plays an important role in intra and inter-sexual competition in birds. Many of the yellow, orange or red colours present in birds are carotenoid dependent. Carotenoids can not be synthetized de novo by birds and consequently should be obtained through their diet, and access to carotenoids may differ between individuals and species. In addition to ornamentation, carotenoids are important for bird physiology and it has been proposed that a trade-off in their allocation to these two functions occurs. Under this scenario parasites may play a central role in maintaining the honesty of plumage as a signaling system by increasing the demands for carotenoids for infection or damage control and/or by reducing carotenoid absorption in the intestines. We analyzed the relationship between (1 carotenoid concentrations in plasma and (2 blood and intestinal parasite richness and abundance in 22 species of passerines sampled in spring. Loads of different groups of parasites were unrelated so conclusions drawn from examining a particular group of parasites cannot be extrapolated to the whole community of pathogens and parasites inhabiting a host. At intraspecific level plasma carotenoid concentration was negatively related to the richness of intestinal parasites and the abundance of some groups of intestinal parasites, at interspecific level plasma carotenoid concentration was negatively related with the abundance of intestinal parasites. No relationship at intra- nor interpecific level was found between carotenoids and blood parasites. The results suggest that intestinal parasites play an important role in the evolution and maintenance of carotenoid-derived sexually selected ornamentations probably through a negative impact on the uptake of carotenoids at the gut.

    Surveys evaluating pain in hospitals keep on showing that postoperative pain (POP) remains undertreated. At the time when guidelines are edited and organisational changes are implemented, more recent data are necessary to check the impact of these measures on daily practice and needs for improvement. This prospective, cross-sectional, observational, multi-centre practice survey was performed in 2004-2005 in 7 European countries. It was conducted in surgical wards of a randomised sample of hospitals. Data on POP management practices following surgery in adult in-patients were collected anonymously via a standardised multiple choice questionnaire. Among 1558 questionnaires received from 746 European hospitals, 59% were provided by anaesthetists and 41% by surgeons. There are no regular on-site staff training programmes on POP management in the institution for 34% of the respondents, patients are systematically provided with POP information before surgery for 48% of respondents; balanced analgesia following major surgery and regular administration of analgesics are largely used; 25% of respondents have specific written POP management protocols for all patients in their ward; 34% of respondents say that pain is not assessed and 44% say that pain scores are documented in the patient's chart. This largest ever performed survey confirms the extensive body of evidence that current POP management remains suboptimal and identifies needs for improvement on European surgical wards. However, the wide use of balanced analgesia and the regular administration of analgesics are indicators of ongoing change. PMID:17703887

    The population of the world has recently passed the 7 billion milestone and as the cost of human genome sequencing is rapidly declining, sequence data of billions of people should be accessible much sooner than anyone would have predicted 10 years ago. This will form the basis of personalised medicine. However it is still not clear, even in principle, whether these data, combined with data of the expression of one's genome in various cells and tissues relevant to different diseases, could be used effectively in clinical medicine and healthcare, or in predicting responses to different therapies. Therefore this is an important issue which needs to be addressed before more resources are wasted on less than informative studies and surveys simply because technologies exist. As a typical example, we have selected and summarise here key studies from the biomedical literature that focus on gene expression profiling of the response to biologic therapies in peripheral blood and biopsy samples in autoimmune diseases such as rheumatoid arthritis, spondylarthropathy, inflammatory bowel diseases and psoriasis. We also present the state of the biotechnology market from a European perspective, discuss how spin-offs leverage the power of genomic technologies and describe how they might contribute to personalised medicine. As ethical, legal and social issues are essential in the area of genomics, we analysed these aspects and present here the European situation with a special focus on Hungary. We propose that the synergy of these three issues: pharmacogenomics, biotechnology and regulatory issues should be considered a triad necessary to succeed in personalised medicine. PMID:22414700

    Malignant central nervous system (CNS) tumors are the leading cause of death by cancer in children and the second commonest pediatric cancer type. Despite several decades of epidemiologic research, the etiology of childhood CNS tumors is still largely unknown. A few genetic syndromes and therapeutic ionizing radiation are thought to account for 5-10% of childhood cancer, but the etiology of other cases remains unknown. Nongenetic causes, like environmental agents, are thought to explain them. However, as very few epidemiologic studies have been conducted, it is not surprising that nongenetic risk factors have not been detected. The biggest difference between cancers for which there are good etiologic clues and those for which there are none could be the number of relevant studies. This study, which covers the 1980-2011 period, identified links between CNS cancer evolution and the socio-economic and environmental indicators in the same space and time limits in the European Union.

    Full Text Available The article considers the main results of political modernization in the Central Asian national outskirts of the Russian Empire taken place in the late 19th – early 20th centuries. The concept “Central Asian national outskirts” includes Stepnoy and Turkistan Governorate Generals, the two administrative-territorial entities founded in the 1860s as a result of a complete joining of the Kazakh camping grounds of the Junior, Middle and Elder zhuzhes; after the Kokand and Khivinsk khanates inhabited by nomads ( the Kirghiz, the Kara-Kalpaks as well as the settled population (the Uzbeks were conquered. The analysis of the sources and materials conducted by the authors asserts that the political modernization of the Central Asian national outskirts proposed by the Russian Empire was carried out in line with the fundamental characteristics of West European civilization and the basis of its political culture. Thus the system of local government was established and the democratic electoral system was introduced by means of expanding the voter’s base, with the region’s population participating in social and political life. The principles of bourgeois ideology based on such concepts as “equality”, “freedom”, “self-determination” were also formed. However, the political modernization of the Central Asian national outskirts should not be considered as complete. Up to 1917 the political sphere of the region’s population was characterized by the predominance of traditional mores, values and laws, whereas clan ideology, tribalism and Muslim ethno-consciousness were characteristic of the social sphere. All these factors affected the process of adapting to western political culture. The institutionalization of the new structures did not go along with the de-institutionalization of the traditional ones, and so resulted in the combination and coexistence of the traditional and modern structures.

    This study details the phylogeographic pattern of the bank vole, Clethrionomys glareolus, a European rodent species strongly associated with forest habitat. We used sequences of 1011 base pairs of the mitochondrial DNA cytochrome b gene from 207 bank voles collected in 62 localities spread throughout its distribution area. Our results reveal the presence of three Mediterranean (Spanish, Italian and Balkan) and three continental (western, eastern and 'Ural') phylogroups. The endemic Mediterranean phylogroups did not contribute to the post-glacial recolonization of much of the Palaearctic range of species. Instead, the major part of this region was apparently recolonized by bank voles that survived in glacial refugia in central Europe. Moreover, our phylogeographic analyses also reveal differentiated populations of bank voles in the Ural mountains and elsewhere, which carry the mitochondrial DNA of another related vole species, the ruddy vole (Clethrionomys rutilus). In conclusion, this study demonstrates a complex phylogeographic history for a forest species in Europe which is sufficiently adaptable that, facing climate change, survives in relict southern and northern habitats. The high level of genetic diversity characterizing vole populations from parts of central Europe also highlights the importance of such regions as a source of intraspecific genetic biodiversity.

    Full Text Available Aim of study: The primary objective of this paper was to compare the effects of different types of forestry machine chassis on the compaction of the top layers of soil and to define the soil moisture content level, at which machine traffic results in maximum compaction.Area of study: Measurements were conducted in eight forest stands located in Slovakia and the Czech Republic. The soil types in the stands subjected to the study were luvisols, stagnosols, cambisols, and rendzinas.Material and Methods: The measurements were focused on tracked and wheeled (equipped with low pressure tyres cut-to-length machines, and skidders equipped with wide and standard tyres. The bulk density of soil was determined from soil samples extracted from the ruts, the centre of the skid trail, and the undisturbed stand. To determine soil moisture content, at which the soil is the most susceptible to compaction, the Proctor standard test was employed.Main results: The moisture content for maximal compaction fluctuated from 12% to 34.06%. Wheeled machines compacted the soil to 1.24 – 1.36 g.cm-3 (30.3 – 35.4 % compaction in dried state. Bulk density of soil in stands where tracked machine operated was lower, ranging from 1.02 to 1.06 g.cm-3 (25.3 % compaction.Research highlights: All wheeled machines caused the same amount of soil compaction in the ruts, despite differences in tyres, machine weight, etc. Maximum compaction caused by forestry machines occurred at minimal moisture contents, easily achievable in European climatic conditions.  Keywords: soil compaction; bulk density; soil moisture content limits; cut-to-length machines; skidders.

  12. Organochlorine pollutants and stable isotopes in resident and migrant passerine birds from northwest Michoacán, Mexico.

    Although concentrations of organochlorine compounds (OCs) in birds from most of the United States and Canada have decreased over the last 30 years, there is still concern that migrant birds might be exposed to elevated concentrations of OCs during migration in Latin America. The Lerma-Chapala Basin in west-central Mexico is an important migration corridor and wintering area for many species. The objectives of this study were to assess if resident and migrant birds wintering in western Michoacán, Mexico accumulated elevated concentrations of OCs during fall and spring and to determine if the stable isotopes delta(15)N, delta(13)C, and deltaD could be used to predict burdens and origins of DDE accumulation. Resident and migrant passerine insectivorous birds were collected during fall and spring (2001-2002) in northwest Michoacán, near Chapala Lake, Mexico. The carcasses were analyzed for OCs and tail feathers were analyzed for stable isotopes delta(15)N, delta(13)C, and deltaD. The OCs detected in more than 50% of the samples were: oxychlordane (79%), p,p'-DDE (100%), p,p'-DDT (57%), and total PCBs (100%). p,p'-DDE was the OC detected at the highest concentrations, whereas residues of other OCs were near or below detection limits. Overall, there were no significant differences in concentrations of OCs between seasons or between resident and migrant birds. Concentrations of DDE and oxychlordane were somewhat higher in migrant and resident birds during spring than in fall; however, concentrations were significantly different only for oxychlordane. Two resident birds collected in fall and spring had DDE residues >10 microg/g wet weight in carcass. There were no significant differences in delta(13)C and delta(15)N values among species, between seasons, or between migrant and resident birds. However, deltaD values were clearly different between species and helped differentiate migrant from resident birds. deltaD values also were negatively and significantly correlated

    The floodwater mosquito Aedes vexans can be a massive nuisance in the flood plain areas of mainland Europe, and is the vector of Tahyna virus and a potential vector of Dirofilaria immitis. This epidemiologically important species forms three subspecies worldwide, of which Aedes vexans arabiensis has a wide distribution in Europe and Africa. We quantified the genetic and phenotypic variation in Ae. vexans arabiensis in populations from Sweden (northern Europe), Hungary, and Serbia (central Europe). A landscape genetics approach (FST , STRUCTURE, BAPS, GENELAND) revealed significant differentiation between northern and southern populations. Similar to genetic data, wing geometric morphometrics revealed two different clusters, one made by Swedish populations, while another included Hungarian and Serbian populations. Moreover, integrated genetic and morphometric data from the spatial analysis suggested groupings of populations into three clusters, one of which was from Swedish and Hungarian populations. Data on spatial analysis regarding an intermediate status of the Hungarian population was supported by observed Isolation-by-Distance patterns. Furthermore, a low proportion of interpopulation vs intrapopulation variance revealed by AMOVA and low-to-moderate FST values on a broader geographical scale indicate a continuous between-population exchange of individuals, including considerable gene flow on the regional scale, are likely to be responsible for the maintenance of the observed population similarity in Aе. vexans. We discussed data considering population structure in the light of vector control strategies of the mosquito from public health importance. PMID:27232139

    Forest phenology and productivity is intimately linked with the actual weather conditions, and in the long term with the local climate. Our current understanding on the environmental control on spring leaf-out and autumn senescence is incomplete. Causes of the interannual variability of tree growth and forest carbon balance are not well understood as well. Satellite remote sensing provides a feasible way to monitor and study the changes of forest functioning in general and to understand its relationship with the climate fluctuations. In the presented study the latest version (Collection 6) of the Enhanced Vegetation Index (EVI) and the Normalized Difference Vegetation Index (NDVI) products calculated from measurements of the MODIS sensor onboard the NASA Terra and Aqua satellites are used to characterize forest activity and its interannual variability in Central Europe (Hungary and Croatia). The applied EVI and NDVI dataset is part of the MOD13 product of NASA and covers the 2000-2015 time period. The newest, Collection 6 dataset is free from the sensor degradation effect (that was present in previous versions) which can contribute to the better characterization of the changes in forest phenology. Using the FORESEE climatological database the effects of drought is studied on the NDVI and EVI variations. Possible lagged effect of severe drought on NDVI variability during the consecutive years is studied at the selected sites. Drivers of forest phenology are studied in terms of linear relationships between temperature and onset/offset of the growing season.

    Full Text Available This paper shows the economic situation of economically weak farms in 8 countries of Central and Eastern Europe(CEE in 2010. The data were obtained from the survey on EU farms carried out under the FADN system. The studyincluded countries in which economically weak farms were the dominant farm type (i.e. Bulgaria, Estonia, Hungary,Latvia, Lithuania, Poland, Romania and Slovakia. The aim of the study was to assess the economic performance ofthose farms and indicate advantages of the competing farm types. The analysis was performed in terms of totalfactor productivity, income levels, assets and debt level. The influence of CAP instruments on managementefficiency was also demonstrated. The study found a high diversity in terms of production potential as well asfinancial condition of farms in particular countries, whereas one point of correspondence between farms is theprevalence of fixed assets, i.e. an excessive assets-to-area ratio, and the dominance of own capital in financingthose assets. Romanian, Polish and Bulgarian farms are characterised by the highest efficiency of use of currentoutlays and, in turn, a lower cost of the production unit, which accounted for 66%, 86% and 87% of the outputvalue respectively. In Latvia, Estonia and Slovenia, the costs exceeded the output value by 6%, 7% and 23%respectively and, as a result, the income of those farms was generated exclusively due to subsidies.

    Full Text Available Abstract Background The identification of vast numbers of unknown organisms using DNA sequences becomes more and more important in ecological and biodiversity studies. In this context, a fragment of the mitochondrial cytochrome c oxidase I (COI gene has been proposed as standard DNA barcoding marker for the identification of organisms. Limitations of the COI barcoding approach can arise from its single-locus identification system, the effect of introgression events, incomplete lineage sorting, numts, heteroplasmy and maternal inheritance of intracellular endosymbionts. Consequently, the analysis of a supplementary nuclear marker system could be advantageous. Results We tested the effectiveness of the COI barcoding region and of three nuclear ribosomal expansion segments in discriminating ground beetles of Central Europe, a diverse and well-studied invertebrate taxon. As nuclear markers we determined the 18S rDNA: V4, 18S rDNA: V7 and 28S rDNA: D3 expansion segments for 344 specimens of 75 species. Seventy-three species (97% of the analysed species could be accurately identified using COI, while the combined approach of all three nuclear markers provided resolution among 71 (95% of the studied Carabidae. Conclusion Our results confirm that the analysed nuclear ribosomal expansion segments in combination constitute a valuable and efficient supplement for classical DNA barcoding to avoid potential pitfalls when only mitochondrial data are being used. We also demonstrate the high potential of COI barcodes for the identification of even closely related carabid species.

    Plastics play an increasingly important role in reaching the recovery and recycling rates defined in the European WEEE Directive. In a recent study we have determined the life cycle environmental impacts of post-consumer plastics production from mixed, plastics-rich WEEE treatment residues in the Central European plant of a market-leading plastics recycler, both from the perspective of the customers delivering the residues and the customers buying the obtained post-consumer recycled plastics. The results of our life cycle assessments, which were extensively tested with sensitivity analyses, show that from both perspectives plastics recycling is clearly superior to the alternatives considered in this study (i.e. municipal solid waste incineration (MSWI) and virgin plastics production). For the three ReCiPe endpoint damage categories, incineration in an MSWI plant results in an impact exceeding that of the examined plastics recycling facility each by about a factor of 4, and the production of virgin plastics has an impact exceeding that of the post-consumer recycled (PCR) plastics production each by a factor of 6–10. On a midpoint indicator level the picture is more differentiated, showing that the environmental impacts of the recycling options are lower by 50% and more for almost all impact factors. While this provides the necessary evidence for the environmental benefits of plastics recycling compared to existing alternatives, it can, however, not be taken as conclusive evidence. To be conclusive, future research will have to address the fate of hazardous substances in the outputs of such recycling systems in more detail. - Highlights: • LCA of plastics production from plastics-rich WEEE treatment residues • Multiple stakeholder perspectives addressed via different research questions • Plastics production from WEEE treatment residues clearly superior to alternatives • Robust results as demonstrated by extensive sensitivity analyses

    Full Text Available The cultural heritage, including, according to the UNESCO definition, the assembly of monuments, groups of buildings, and sites which are of outstanding universal value from the historical, aesthetic, ethnological or anthropological point of view, represents an important asset that can be engaged and capitalized in order to support the sustainable development. Meeting the needs of the present without compromising the ability of the future generations to meet their own needs in order to provide a better quality of life for everyone, now and for generations to come, has become a concern and, in the same time, a priority for all the stakeholders of the society. Turning to the best account of the cultural heritage also represents an important driver for the sustainable development of the travel and tourism industry, as the cultural sites, institutions, goods and services, appropriately capitalized, represent significant attractions for the international and domestic tourists. The integration of the principles of sustainable development in the current functioning of the travel and tourism industry led to the development and implementation of the concept of sustainable tourism. The paper explores in a distinctive manner the relationships between the cultural heritage and the travel and tourism industry, respectively the cultural heritage and the sustainable development based on a set of related statistical indicators, and the specific secondary data, expressing the extent of the cultural heritage, the development of the travel and tourism industry, and the attained level of sustainable development in ten Central and Eastern European countries, members of the European Union. There are two major research questions the paper aims to answer: (1 How significant is the relationship between the cultural heritage and the development of the travel and tourism industry? (2 Is there a noteworthy connection between the cultural heritage and the sustainable

    The first biosimilar monoclonal antibody (infliximab, CT-P13) was registered by the European Medicines Agency in 2013 for the treatment of several inflammatory conditions including rheumatoid arthritis (RA). Biosimilar infliximab is first being marketed in the Central and Eastern European countries. This paper presents the estimated budget impact of the introduction of biosimilar infliximab in RA over a 3-year time period in six selected countries, namely Bulgaria, the Czech Republic, Hungary, Poland, Romania and Slovakia. A prevalence-based model was constructed for budget impact analysis. Two scenarios were compared to the reference scenario (RSc) where no biosimilar infliximab is available: biosimilar scenario 1 (BSc1), where interchanging the originator infliximab with biosimilar infliximab is disallowed, and only patients who start new biological therapy are allowed to use biosimilar infliximab; as well as biosimilar scenario 2 (BSc2), where interchanging the originator infliximab with biosimilar infliximab is allowed, and 80% of patients treated with originator infliximab are interchanged to biosimilar infliximab. Compared to the RSc, the net savings are estimated to be €15.3 or €20.8 M in BSc1 and BSc2, respectively, over the 3 years. If budget savings were spent on reimbursement of additional biosimilar infliximab treatment, approximately 1,200 or 1,800 more patients could be treated in the six countries within 3 years in the two biosimilar scenarios, respectively. The actual saving is most sensitive to the assumption of the acquisition cost of the biosimilar drug and to the initial number of patients treated with biological therapy. The study focused on one indication (RA) and demonstrated that the introduction of biosimilar infliximab can lead to substantial budget savings in health care budgets. Further savings are expected for other indications where biosimilar medicines are implemented.

    Disturbance dynamics in forest ecosystems shows signs of perturbation in the light of changing climate regimes with the frequency and intensity of events (e.g. pathogens in North America and Central Europe) amplified, becoming more frequent and severe. The montane Norway spruce (Picea abies) dominated forests of Central Europe are a niche habitat and environment; situated outside their natural boreal distribution (e.g. Fenno-Scandinavia). These communities are at or near their ecological limits and are vulnerable to both short term disturbances (e.g. fire, windstorm and pathogens) and longer-term environmental change (e.g. climate induced stress and changing disturbance patterns). Researches have linked negative impacts on spruce forest with both wind disturbance (wind-throw) and outbreaks of spruce bark beetle (Ips typographus), and there is growing evidence for co-association with wind damage enhancing pathogenic outbreaks. Examples include: in the Bohemian Forest (Czech Republic) the mid-1990s spruce bark beetle outbreak and the 2007 windstorm and subsequent bark beetle outbreak. In the High Tatra Mountains (Slovakia) there is a further co-association of forest disturbance with windstorms (2004 and 2014) and an ongoing bark beetle outbreak. The scale and severity of these recent outbreaks of spruce bark beetle are unprecedented in the historical forest records. Here, findings from ongoing research developing and integrating data from dendroecological, sedimentary palaeoecological and geochemical time series to develop a longer-term perspective on forest dynamics in these regions. Tree-ring series from plots or forest stands (>500) are used alongside lake (5) and forest hollow (3) sediments from the Czech and Slovak Republics to explore the local, regional and biogeographical scale of forest disturbances. Dendroecological data showing tree-ring gap recruitment and post-suppression growth release highlight frequent disturbance events focused on tree or forest

    Mass size distributions of atmospheric aerosols have been sampled in the region of Vienna, a typical city in central Europe, at an urban and a rural site. The aerosol was collected simultaneously by cascade impactors. Two experiments which had a duration of 4 weeks each, were performed in August 1999 and in January/February 2000. Daily sampling periods were from 8:00 to 20:00, and from 20:00 to 8:00. An evaluation of the mass size distributions is represented in this paper. Emphasis is on the relationships of different aerosol components in a local and a regional context. The main results are as follows. The main components of the atmospheric aerosol are a fine aerosol, the accumulation aerosol, and a coarse aerosol. Specific coarse modes with modal diameters of 4.7 μm average and geometric standard deviations of about 3 occur at the urban and at the rural site, some times surprisingly strong. The fine and the coarse modes are very likely related to motor-car traffic. Usually the PM 2.5 and PM 10 aerosols are regionally strongly correlated. Occasionally, this correlation is effectively disturbed by local and/or regional emissions. Time series of correlation coefficients reveal an episodic character of the atmospheric aerosol. Periods of strong inter-site correlations of PM 2.5 and PM 10 indicate the dominance and the co-variation of the accumulation aerosols or the dominance and the co-variation of the coarse modes.

    Earlier migration in males than in females is the commonest pattern in migrating passerines and is positively related to size dimorphism and dichromatism. The early arrival of males is a costly trait that may confer reproductive advantages in terms of better territories and/or mates. Given the physiological cost of migration, early migrants are those in best condition and accordingly the prevalence, load, and/or diversity of parasites is expected to increase in both sexes for late migrants.

    Bird species vary greatly in the duration of their annual complete feather molt. However, such variation is not well documented in birds from many biogeographic areas, which restricts our understanding of the diversification of molt strategies. Recent research has revealed that molt duration can be estimated in passerines from ptilochronology-based measurements of the growth rate of their tail feathers. We used this approach to explore how molt duration varied in 98 Nearctic species that have...

    Norway rats (Rattus norvegicus) were introduced to the Falkland Islands and are detrimental to native passerines. Rat eradication programmes are being used to help protect the avifauna. This study assesses the effectiveness of eradication programmes while using this conservation practice as a natural experiment to explore the ecological resistance, resilience and homeostasis of bird communities. We conducted bird surveys on 230 islands: 85 in the presence of rats, 108 that were historically free of rats and 37 from which rats had been eradicated. Bird detection data were used to build occupancy models for each species and estimate species-area relationships. Count data were used to estimate relative abundance and community structure. Islands with invasive rats had reduced species richness of passerines and a different community structure than islands on which rats were historically absent. Although the species richness of native passerines was remarkably similar on eradicated and historically rat-free islands, community structure on eradicated islands was more similar to that of rat-infested islands than to historically rat-free islands. The results suggest that in the Falkland Islands, species richness of passerines is not resistant to invasive rats, but seems to be resilient following their removal. In contrast, community structure seems to be neither resistant nor resilient. From a conservation perspective, rat eradication programmes in the Falkland Islands appear to be effective at restoring native species richness, but they are not necessarily beneficial for species of conservation concern. For species that do not recolonize, translocations following eradications may be necessary. PMID:25355608

  14. Products of micritization: evidences of microbial activity at and below the seafloor of the Upper Moscovian epicontinental basin of central European Russia

    2003-01-01

    Thin sections of the Upper Moscovian shallow-marine limestones of central European Russia exhibit various products of synsedimentary and earliest diagenetic degradation of carbonate allochems. Micritized grains and related features (microcrystalline overgrowths, oncoids, and endolithic borings) are very similar to modern micritized grains forming on the shallow protected seafloors of warm-water carbonate basins. Surface-sediment micritization in the late Moscovian epicontinental basin of central European Russia is expressed in microendolithic destruction, micrite-minimicrite precipitation in intraskeletal voids, and non-selective replacements of the original skeletal structures. Most conspicuous products of surface-sediment micritization are peloidized large foraminifers (fusulinoids and palaeotextulariids), micritic-minimicritic envelopes on brachiopod and echinoderm bioclasts, and internal micritization in echinoderm stereomal pores. The last feature is structurally controlled and where not related to other surface-sediment alterations, may be attributed to intrasedimentary degradation. Surface-sediment micritization was produced by a syntrophic microbial community that must have included phototrophic cyanobacteria and/or chlorophytes and heterotrophic bacteria and fungae responsible for the intragranular microcrystalline recrystallization and internal cementation. Microborings are diverse, include microbial and metazoan varieties. Microendolithic destruction and subsequent microcrystalline occlusion of borings was locally important in micritizing processes, although cinder-like peripheral replacements in massive bioclasts and persistence of test walls in deeply peloidized foraminifers suggest that recrystallization and internal cementation was equally or more important. Many skeletal packstones, wackestones, mudstones, and tempestites irrespectible of their inferred paleobathymetric position exhibit the signs of selective intrasedimentary degradation: peripheral

    We investigated in total 80 wine samples of different types and seven grape juice and 23 beer samples purchased from markets in Central Europe in order to understand the arsenic (As) speciation and help assess the potential As toxicity via intake of alcoholic beverages. Generally, total As concentrations in most samples investigated were below the drinking water limit 10 µg l(-1) published by the World Health Organization (WHO); ranging from 0.46 to 21.0 µg l(-1) As in red and white wines and from 0.75 to 13.4 µg l(-1) As in beers. In addition, concentrations of total As in rice wine and in rice beer were 0.63-6.07 and 3.69-8.23 µg l(-1) As, respectively. The total As concentrations in ice wine ranged from 7.94 to 18.8 µg l(-1) As, significantly higher than in white and red wine. Arsenite predominated as the As species in most of the wine samples, whereas arsenate was the dominant species in rice wine, beer and rice beer. Methyl As components were usually minor components in all wine and beer samples. Monomethylarsonic acid, dimethylarsinic acid and two additional unknown As species were frequently found in grape juice, late harvest and ice wine with higher sweetness. After air exposure, arsenite, arsenate, monomethylarsonic acid and dimethylarsinic acid were stable at 4°C for months, probably due to the acidic conditions of wine and beer samples. The presence of sulfite had little influence on As speciation in wine. Despite the predominance of more toxic arsenite and arsenate in wine and beer, the estimated weekly exposure to As (via consumption of beer, wine and rice wine) is low. The As intake per capita is 6.81 µg from beer, <1.93 µg from wine and 0.88 µg from rice wine, estimated using the median of total As concentration multiplied by the average consumption per capita of the corresponding beverage.

    Full Text Available Geolocators are small light-weight data loggers used to track individual migratory routes, and their use has increased exponentially in birds. However, the effects of geolocators on individual performance are still poorly known. We studied geolocator effects on a long-distance migrating passerine bird, the northern wheatear (Oenanthe oenanthe L.. We asked the general question of whether geolocators affect migratory behaviour and subsequent reproductive performance of small passerines by comparing arrival time, breeding time, breeding success and survival of geolocator versus control birds of known identity and breeding history. During two years geolocator birds (n=37 displayed a lower apparent survival (30% as compared to controls (45%, n=164. Furthermore, returning geolocator birds (n=12 arrived on average 3.5 days later, started laying eggs 6.3 days later, and had lower nest success (25% than control birds (78%. Our results suggest that geolocators affect migratory performance with carry-over effects to the timing of breeding and reproductive success in the subsequent breeding season. We discuss the implications of such geolocator effects for the study of migratory strategies of small passerines in general and suggest how to identify and investigate such effects in the future.

    This paper describes the distribution and behavior of passerine birds within 1 km of Peregrine Falcon Falco peregrinus eyries in western Greenland. Passerine populations were censused in 1983 around six cliffs occupied by nesting Peregrines and at six sites on the open tundra, and in 1984 at two unoccupied sites suitable for Peregrine nesting. Four passerine species accounted for over 90% of birds seen. Within 400 m of Peregrine occupied cliffs, three species, Lapland Longspur Calcarius lapponicus. Northern Wheatear Oenanthe oenanthe, and Common Redpoll Carduelisflammea, were found in lower than average abundance while the fourth, Snow Bunting Plectrophenax nivalis, was found in increased abundance. Our indirect tests suggest that Peregrine presence, rather than direct predation, was responsible for the distributions of the first three species. The Snow Bunting, however, behaviourally adapts to Peregrine presence in order to exploit nesting habitat available at the cliff base. These results contrast strongly with those reported by other Arctic workers, where increased abundances of potential prey were observed in close proximity to nesting Peregrines.

    The 18 species of bird studied originally are known to belong to muscicapids, robins and sylviids of passerines, but some disputations are always present in their classification systems. In this experiment, phylogenetic relationships of 18 species of passerines were studied using Adenylate Kinase Intron 5 (AK5) sequences and DNA techniques. Through sequences analysis in comparison with each other, phylogenetic tree figures of 18 species of passerines were constructed using Neighbor-Joining (NJ) and Maximum-Parsimony (MP) methods . The results showed that sylviids should be listed as an independent family, while robins and flycatchers should be listed into Muscicapidae. Since the phylogenetic relationships between long-tailed tits and old world warblers are closer than that between long-tailed tits and parids, the long-tailed tits should be independent of paridae and be categorized into aegithalidae. Muscicapidae and Paridae are known to be two monophylitic families, but Sylviidae is not a monophyletic group. AK5 sequences had better efficacy in resolving close relationships of interspecies among intrageneric groups.

    2016-04-01

    This study was undertaken to examine the vertical and lateral geochemical differentiation of 0.25-0.05 mm sand fraction partitioned from uncontaminated forest soils on the central part of the Russian Plain. The vertical distribution of Fe, Ti, Mn, Zr, Zn, Cu, Cr, Ni, Pb and Co was examined in 5 soil profiles: two podzoluvisols developing on sheet loam on interfluvial summits, two poorly differentiated soddy and soddy gleyic soils occupying slope and footslope positions, and one floodplain soil. The spatial variations of 0.25-0.05 mm fraction geochemistry were characterized using elemental data from the humus horizons of two soil catenas and the topsoil of an erosional landform (a gully system), typical for the study area. Analyses show the following median concentrations in the sand fraction: Fe - 3,2%, Ti - 3000 ppm, Mn - 500 ppm, Zr - 640 ppm, Zn, Cu, Cr - 50 ppm, and Ni, Pb and Co - 23, 18 and 8 ppm, respectively. Variation coefficients diminish in magnitude: Mn, Cu (70-80%) > Co, Zn, Ni, Fe (60-65%) >Zr, Ti (45%) > Cr, Pb (35%). The sand fraction content in the soils varied widely, from 0.4 to 56% depending on the lithological features of parent material and underlying strata. No even distribution of the fraction across soil profiles was registered. In soils on loamy deposits sand enrichment was observed in the upper horizons, in contrast to the lower horizons for soils underlain by sandy glacio-fluvial deposits. The higher contents of metals in the sand fraction in all soil profiles were found in the topsoil, characterized by more active humus accumulation, biogeochemical processes and sand grain weathering. However, Ti and Zr were distributed more evenly, implying their presence in a form of stable primary minerals. The spatial distribution of the metals in 0.25-0.05 mm particles revealed important soil-geochemical convergence processes in lateral direction along catenas. Fraction samples partitioned from soils in the lowermost positions on the two catenas

    The influence of long-term "dry" and "wet" climatic cycles on the water regime, hydrological parameters, and carbonate profiles of chernozems in Central European Russia and adjacent territories was studied. The hydrological and carbonate profiles were found to change during the wet cycle. However, the upper part of the hydrological profile is basically unchanging, whereas in its lower part, the number of hydrological horizons and contrast in their moistening decrease in the forest-steppe chernozems and increase in the steppe chernozems. The frequency of through wetting of chernozems increases during the wet cycles. The vertical lithological heterogeneity of the parent material affects the soil moisture status. In the wet climatic cycle, the moisture content above the lithological contact increases resulting in the development of the features of soil hydromorphism. In the carbonate profile, the character of pedofeatures is changing: some carbonate neoformations disappear, while the other ones develop. Possible variations of the periodically percolative water regime were revealed in chernozems. The classification of water regime proposed by A.A. Rode may be updated based on the data obtained during the dry climatic cycle. Rode's hypothesis about cyclic variations in the soil water regime is confirmed.

  1. Geothermal energy systems assessment. - A strategic assessment of technical, environmental, institutional and economic potentials in Central and Eastern European countries. Vol. 1: Main report

    International Nuclear Information System (INIS)

    Despite considerable effort, the Central and Eastern European Countries (CEECs) still face serious environmental problems related to their heating sectors. This is mainly due to the fact that most CEECs continue to rely heavily on conventional and polluting energy sources such as lignite, coal and heavy fuel-oil. However, increasing awareness and interest in converting to renewable and non-traditional energy sources are emerging in the region, strongly encouraged by the international community. Within the CEECs, geothermal energy is considered to be one of the most promising local energy sources. Geothermal water is found in significant quantity underground in the CEECs aspiring to become an important future environmentally friendly energy source for heating purposes. In view of this, the Danish Environmental Protection Agency (DEPA) commissioned Kvistgaard Consult to prepare a strategic study of economic, environmental, technical and institutional potentials of geothermal energy systems in the CEECs. As part of the study, an international workshop was held. An important conclusion from the workshop as well as from the study, is that the CEECs possess highly promising environmental and technical potentials for further development of geothermal energy systems for heating purposes. The study recommends concrete action proposals to be considered by DEPA. Volume 1 is the main report presenting the results of the Geothermal Energy Systems Assessment Project (GESA). (BA)

    Lead originating from coal burning, gasoline burning, and ore smelting was identified in 210Pb-dated profiles through eight peat bogs distributed over an area of 60,000 km2. The Sphagnum-dominated bogs were located mainly in mountainous regions of the Czech Republic bordering with Germany, Austria, and Poland. Basal peat 14C-dated at 11,000 years BP had a relatively high 206Pb/207Pb ratio (1.193). Peat deposited around 1800 AD had a lower 206Pb/207Pb ratio of 1.168-1.178, indicating that environmental lead in Central Europe had been largely affected by human activity (smelting) even before the beginning of the Industrial Revolution. Five of the sites exhibited a nearly constant 206Pb/207Pb ratio (1.175) throughout the 19th century, resembling the "anthropogenic baseline" described in Northern Europe (1.17). At all sites, the 206Pb/207Pb ratio of peat decreased at least until 1980; at four sites, a reversal to more radiogenic values (higher 206Pb/207Pb), typical of easing pollution, was observed in the following decade (1980-1990). A time series of annual outputs for 14 different mining districts dispersing lead into the environment has been constructed for the past 200 years. The production of Ag-Pb, coal, and leaded gasoline peaked in 1900, 1980, and 1980, respectively. In contrast to other European countries, no peak in annual Pb accumulation rates was found in 1900, the year of maximum ore smelting. The highest annual Pb accumulation rates in peat were consistent with the highest Pb emission rates from coal-fired power plants and traffic (1980). Although maximum coal and gasoline production coincided in time, their isotope ratios were unique. The mean measured 206Pb/207Pb ratios of local coal, ores, and gasoline were 1.19, 1.16, and 1.11, respectively. A considerable proportion of coal emissions, relative to gasoline emisions, was responsible for the higher 206Pb/207Pb ratios in the recent atmosphere (1.15) compared to Western Europe (1.10). As in West European

    Woody vegetation has been linked to increased rates of Brown-headed Cowbird (Molothrus ater) parasitism for some grassland hosts. In northern North Dakota, however, studies reported that parasitism of grassland passerine nests was lower in landscapes with trees than in those without trees. We looked for evidence of this pattern elsewhere, using data from two studies conducted on the Sheyenne National Grassland in southeastern North Dakota. Specifically, we examined the probability of parasitism relative to percent tree cover within 2 km of a nest. We found a negative relationship for grassland passerine nests of all species tested. Our results support the suggestion that cowbirds are less likely to parasitize nests of grassland passerines where tree cover on the landscape is greater. This pattern could be explained by cowbirds switching to alternative hosts in woodlands, but this hypothesis needs further testing. ?? 2009 by The Cooper Ornithological Society. All rights reserved.

  4. Predator Control as Part of a Land Management System: Impacts on Breeding Success and Abundance of Passerines

    Directory of Open Access Journals (Sweden)

    Stoate, C.

    2005-06-01

    Full Text Available Control of nest predators such as the Corvidae is regarded as an important component of the management system for wild gamebirds. Although there is strong evidence of an impact of corvid control on nesting success of passerines, the relative roles of nest predation, winter food and other potential influences on breeding abundance of passerines are poorly understood. This study investigates the implications for passerines of cessation of predator control within a game management system in lowland England. The paper discusses results for the two years following cessation of predator control, relative to those from earlier years. These preliminary results suggest that there are complex interactions between human behavioural influences, the abundance of species regarded as 'pests' and the abundance of those targeted for conservation.

    Full Text Available Abstract
    The European wild rabbit (Oryctolagus cuniculus has been recurrently introduced into Italy since the Roman times. Some populations occur along sandy coastal dunes (Central Italy. There is no information about the ecology and habitat preferences of wild rabbits in this particular ecosystem. During May and June 2009, we assessed the distribution of wild rabbits in a 120 ha protected area (province of Livorno, Tuscany, by faecal pellet counts in 170 circular plots (d = 1 m. Range size defined by Kernel Analysis was 27.3 ha (95% and 13.2 ha (50%. Habitat selection was assessed through Jacobs’ index of selection. Rabbits selected the first dunes that offer both food (psammophilous grasses and the cover of tamarisk shrubs. Holm oak woods and pinewoods were avoided, probably because of the lack of undergrowth.

    The structure and evolution of the Trans-European Suture zone (TESZ), contact between Precambrian Europe to the northeast and Phanerozoic terranes to the southwest is one of the main tectonic questions in Europe. The knowledge of the crustal structure, lithosphere-asthenosphere boundary and mantle transition zone between two seismic discontinuities at depths "410" and "660" km, is one of the most important issues to understand the Earth's dynamics. To create a mantle model of the TESZ and surroundings we used different seismic data collected along the 950 km long POLONAISE'97 profile P4. Previous results of 2-D ray-tracing and P-wave travel time modelling and new results of P-wave travel time residuals methods and receiver function sections provide facts about the seismic structure from the surface down to 900 km depth. In the TESZ a large basin, about 125 km wide, is filled with sedimentary strata (Vp 7.0 km s - 1 ) along most of the P4 profile. However, lower values to the southwest may indicate the termination of Baltica. High velocity (~ 8.35 km s - 1 ) uppermost mantle lies beneath the Avalonia/Variscan terranes, and may be due to rifting and/or subduction. The seismic lithosphere thickness for the EEC is about 200 km, while it is only 90 km in the Palaeozoic platform (PP). The mantle transition zone is shallower and about 30 km thicker under the EEC, which could be due to thermal conditions (lower temperature) and/or the presence of water and FeO. The result of this paper is a new compiled and integrated seismic velocity model, available in digital form down to 900 km depth ( http://www.igf.fuw.edu.pl/p4-mantle), which can be used as a preliminary model of the crust and upper mantle in the TESZ area in Central Europe.

    Full Text Available The recent European debt crisis has generated a growing importance of the ECB. The central bank was forced to take measures far beyond its traditional role to stabilize monetary markets and inflation. The European central bank has adopted a new function as lender of last resort, providing banks and governments with almost unlimited liquidity. The new and unconventional monetary policy has been hotly debated. In Germany the debate even reached the Constitutional Court. The article will give a survey of the debate referring to the arguments of the ECB versus Deutsche Bundesbank. It is indeed questionable whether the ECB has a mandate for its new role in monetary and by the way also fiscal policy. Whatever the arguments are convincing, new steps towards fiscal arrangements and a deeper political cooperation are needed to stabilize the euro area.

    2007-02-01

    Full Text Available Abstract Background Passerines (perching birds are widely studied across many biological disciplines including ecology, population biology, neurobiology, behavioural ecology and evolutionary biology. However, understanding the molecular basis of relevant traits is hampered by the paucity of passerine genomics tools. Efforts to address this problem are underway, and the zebra finch (Taeniopygia guttata will be the first passerine to have its genome sequenced. Here we describe a bioinformatic analysis of zebra finch expressed sequence tag (EST Genbank entries. Results A total of 48,862 ESTs were downloaded from GenBank and assembled into contigs, representing an estimated 17,404 unique sequences. The unique sequence set contained 638 simple sequence repeats (SSRs or microsatellites of length ≥20 bp and purity ≥90% and 144 simple sequence repeats of length ≥30 bp. A chromosomal location for the majority of SSRs was predicted by BLASTing against assembly 2.1 of the chicken genome sequence. The relative exonic location (5' untranslated region, coding region or 3' untranslated region was predicted for 218 of the SSRs, by BLAST search against the ENSEMBL chicken peptide database. Ten loci were examined for polymorphism in two zebra finch populations and two populations of a distantly related passerine, the house sparrow Passer domesticus. Linkage was confirmed for four loci that were predicted to reside on the passerine homologue of chicken chromosome 7. Conclusion We show that SSRs are abundant within zebra finch ESTs, and that their genomic location can be predicted from sequence similarity with the assembled chicken genome sequence. We demonstrate that a useful proportion of zebra finch EST-SSRs are likely to be polymorphic, and that they can be used to build a linkage map. Finally, we show that many zebra finch EST-SSRs are likely to be useful in evolutionary genetic studies of other passerines.

  12. Greater sage-grouse as an umbrella species for shrubland passerine birds: a multiscale assessment

    Working groups and government agen-cies are planning and conducting land actions in sagebrush (Artemisia spp.) habitats to benefit Greater Sage-Grouse (Centrocercus urophasianus) populations. Managers have adopted an umbrella concept, creating habitat characteristics specific to sage-grouse requirements, in the belief that other wildlife species dependent on sagebrush will benefit. We tested the efficacy of this approach by first identifying the primary environmental gradients underlying sagebrush steppe bird com-munities (including Greater Sage-Grouse). We integrated field sampling for birds and vegetation with geographic information system (GIS) data to characterize 305 sites sampled throughout the current range of Greater Sage-Grouse in the Intermountain West, United States. The primary environmental axis defining the bird community represented a gradient from local-scale Wyoming/basin big sagebrush (A. t. ssp. wyomingensis/A. t. ssp. tridentata), and bare ground cover to local and regional grassland cover; the second axis repre-sented a transition from low-elevation Wyoming/basin big sagebrush and bare ground to mountain big sagebrush (A. t. ssp. vaseyana) and habitat edge. We identified the relative overlap of sage-grouse with 13 species of passerine birds along the multiscale gradients and estimated the width of the umbrella when applying management guidelines specific to sage-grouse. Passerine birds associated with sagebrush steppe habitats had high levels of overlap with Greater Sage-Grouse along the multiscale environmental gradients. However, the overlap of the umbrella was prima-rily a function of the broad range of sagebrush habitats used by sage-grouse. Management that focuses on creating a narrow set of plot-scale con-ditions will likely be less effective than restoration efforts that recognize landscape scale heterogene-ity and multiscale organization of habitats. These multiscale efforts may improve some sage-grouse habitats and strengthen the

    Since 1995 the European Commission, through the SAVE programme, and the Economic Commission for Europe of the United Nations, through the Energy Efficiency 2000 Project, jointly sponsored the so called SACHA projects in Central and Eastern European Countries regarding major household appliances. Consistently, the main objective of the projects was to analyse and interpret the situation of refrigerators, freezers and washing machines in seven CEEC, so as to increase the knowledge and understanding of the issues at stake in the area of energy efficiency and environmental friendliness, and therefore to identify possible scenarios of improvement. This paper describes the work accomplished and the results achieved in this context, focusing more on the data collection and market survey moments and illustrates, with an abundant series of exhibits, the quantitative picture resulting form the analyses carried out. Possibility exists for replication in Latin America, where ENEA and Italian experience could be fruitfully applied. Reliable and complete information is in fact one of the prerequisites to overcome potential barriers and facilitate a successful enforcement of any energy efficiency policy. Effective implementation and regional harmonisation are necessary, even if projects can facilitate the fulfilment of these goals as it provides a consolidated methodology and an integrated scheme for basic data collection and analysis.

    During the Late Cretaceous to Early Tertiary some parts of the Central European Basin System (CEBS) were uplifted along NW-SE to WNW-ESE striking compressive fault systems. As a result Pre-Zechstein (Permian) basement is exposed at the southern border of the CEBS from Central Germany to the sudetes still further east (e.g. Harz Mountains, Thuringian Forest). Thrust-related basins like the Subhercynian Cretaceous Basin (SCB) in the foreland of the Harz Mountains accumulated up to 2500m of siliciclastic and chemical sediments in only 10 million years (Late Turonian to Lower Campanian, Voigt et al., 2006). By means of low-temperature thermochronology it is possible to characterise these basin inversion processes with respect to timing, pattern and rates of cooling and exhumation. Differed authors have already applied Apatite Fission Track analysis (AFT) in certain areas of the southern margin of CEBS. Thomson and Zeh (2000) published AFT apparent ages of 69 to 81 Ma for the Ruhla Crystalline Complex in the Thuringian Forest. Similar AFT-ages (73-84 Ma) of granitoids from the Harz Mountains were reported by Thomson et al. (1997). The late Carboniferous felsic volcanic rocks near Halle yield a much broader range of AFT apparent ages (75-108 Ma; Jacobs and Breitkreuz, 2003). Comparable AFT-ages (84-90 Ma) had been also observed for gabbros from the north-eastern part of the Mid German Crystalline High (Ventura et al. 2003). The present study tries to bridge some of the major gaps in the regional distribution of thermochronological data by analysing samples from central and southern parts of the CEBS. Overall almost 50 AFT-ages from Saxony-Anhalt, Lower Saxony, Thuringia, Hesse and North Rhine-Westphalia were measured. Emphasis is placed on the regions from the Harz Mountains to the Rhenish Uplands and the Thuringian Forest and its foreland. Furthermore, apatite (U-Th)/He thermochronology is used to better constrain the time-temperature history models. Apart from some

    Full Text Available Local and regional differences in the snow formation were studied in different landscapes of the central part of the East European Plain – within reserves in the Moscow and Tver’ regions (south-north direction; the study period is the winter 2011/12. The observed increase of snow storage in 1.3–1.5 times in the direction south-north is connected, apparently. The difference in the five-day appearance of snow cover maximum is related to differences in regional winter air temperature. Throughout the snow depth and snow storage in spruce are smaller than in deciduous forest – in the ratio of 0.81 in south area and 0.93 in north area; in spruce the large part of solid precipitation is intercepted by the crowns pine trees. Snow stratigraphy at south areas has four layers, six layers at the north area are more variable in snow density and snow storage. Perhaps, gravitational conversion is more noticeable due to larger snow depth. Snow density and snow storage at the open areas are more heterogeneous than in the forest. This is due to sharp fluctuations in air temperature, wind transport and compaction of snow, evaporation from the snow surface. The stratigraphy of snow also reflects the history of winter changes of air temperature and snow accumulation. Common feature for reserves at south and north is the availability of layers with maximum snow storage in the middle of the snow thickness, which were formed during the air temperature drops to the lowest seasonal values in period with increase of snow depth to maximum. Formation of depth hoar in snow thickness are touched everywhere the bottom and middle layers, respectively, it was formed both before and during the period with minimal air temperature. Thus, the results of experimental studies confirm the significance of the differences of individual components of the landscape setting. Analytical conclusions are largely qualitative in nature due to the lack to date of initial information, and

    The etiology of tumors in young age is not precisely known yet, but studies on the topic generally agree that in this group of patients the traditionally known behavioural risk factors (tobacco and alcohol abuse) play no or a significantly less important role. Oral squamous cell carcinoma occurring at a young age is a topic of utmost importance that is extensively and intensively researched as, while the overall incidence of oral cancer is decreasing worldwide, that of squamous cell carcinoma diagnosed in young adults is steadily increasing. The present article aims at presenting the main questions and characteristics of tumors in young adults in Central-Eastern Europe and in developed West European countries as contrasted to tumors found in middle aged and elderly patients. Factors influencing the development of oral cancer include regulatory factors of the cell cycle, the inherited vulnerability of the genetic code of certain proteins and the presence of HPV infection with an oncogenic genotype. The connections of HPV infection and genetic damages are studied intensively. It is known that the prevalence of oral HPV infections is growing with a background of potentially changing sexual habits. It is debated, however, whether smoking and alcohol consumption could have a connection to HPV associated oral cancer and whether the spread of HPV in itself could be an explanation for the growing occurrence of young-age tumors. There is no consensus in the literature as to the prognostic significance of age. Some research groups have found a better life expectancy for young patients, while other authors found a worse prognosis for these patients. It is known that the prognosis of head and neck tumors, the prevalence of HPV infections as well as genetic mutations show regional and ethnic variations. This might be explained by differences in the degree of development of a preventive system, in the quality of care and in the attitudes of young patients towards visiting a

    The combined study of tree-ring width and stable C and O isotopes provides insight in the coherences between carbon allocation during stem growth and the preceding conditions of gas exchange and formation of photosynthates as all influenced by environmental variation. In this large-scale study comprising 10 sites across a range of climate gradients (temperature, precipitation) throughout Central Europe, we investigated tree-rings in European beech (Fagus sylvatica) and Norway spruce (Picea abies) trees. The sampling design included larger and smaller trees. The short-term, i.e. year-to-year, variability in the isotope time series over 100 yrs was analyzed in relation to tree-ring growth and climate variation. The generally strong correlation between the year-to-year differences in δ13C (corrected for the atmospheric shift due to 13C-depleted CO2 from fossil combustion) and δ18O across most sites emphasized the role of stomatal conductance in controlling leaf gas exchange. However, the correlation between both isotopes decreased during some periods. At several sites this reduction in correlation was particularly pronounced during recent decades. This suggests a decoupling between stomatal and photosynthetic responses to environmental conditions on the one hand, and carbon allocation to stem tissue on the other hand. Variability in the isotopic ratio largely responded to summer climate, but was weakly correlated to annual stem growth. In contrast, climate sensitivity of radial growth in both species was rather site-dependent, and was strongest at the driest (in terms of soil water capacity) site. We will also present results of isotope responses with respect to extreme climate events. Understanding the underlying physiological mechanisms controlling the short-term variation in tree-ring signals will help to assess and more precisely constrain the possible range of growth performance of these ecologically and economically important tree species under future climate

  19. Moult Strategies Affect Age Differences in Autumn Migration Timing in East Mediterranean Migratory Passerines

    Science.gov (United States)

    Kiat, Yosef; Izhaki, Ido

    2016-01-01

    Adult passerines renew their flight feathers at least once every year. This complete moult occurs either in the breeding areas, just after breeding (summer moult), or, in some long-distance migratory species, at the non-breeding areas, after arrival to the southern wintering area at the end of autumn migration (winter moult). The aim of this study was to relate moult strategies with the DMD, the difference in median migration date, through Israel, between juveniles and adults. Our data on autumn migration timing in juveniles and adults was based on ringing data of 49,125 individuals belonging to 23 passerine species that breed in Europe and Western Asia and migrate through Israel. We found that DMD was associated with moult timing. In all species that perform a winter moult, adults preceded juveniles during autumn. Among migrants who perform a summer moult, we found evidence of both migration timing patterns: juveniles preceding adults or adults preceding juveniles. In addition, in summer moulters, we found a significant, positive correlation between mean breeding latitude and DMD. Although previous studies described that moult duration and extent can be affected by migration, we suggest that moult strategies affect both migration timing and migration strategy. These two moult strategies (summer or winter moult) also represent two unique migration strategies. Our findings highlight the evolutionary interplay between moult and migration strategies.

    We measured the concentration of several elements (arsenic [As], calcium [Ca], cadmium [Cd], copper [Cu], nickel [Ni], lead [Pb], selenium [Se] and zinc [Zn]) in adult and nestling pied flycatchers (Ficedula hypoleuca) and great tits (Parus major) at different distances to a Cu-Ni smelter in 2009. Feces of nestlings generally failed to correspond with internal element concentrations but reflected the pollution exposure, indicating an increased stress by removal of excess metals. The uptake of Cu and Ni were regulated, but As, Cd, Pb and Se accumulated in liver tissue. Pied flycatchers had generally higher element concentrations than great tits. The higher accumulation of As and Pb in pied flycatcher livers was explained by a more efficient absorption, whereas the higher Cd concentration was primarily due to different intake of food items. Age-related differences occurred between the two species, though both Cd and Se accumulated with age. - Highlights: > We measured metal concentrations in feces and livers of two passerine species. > We examined species- and age-related differences in polluted environments. > Feces was evaluated as a useful non-destructive measure of increased stress. > Generally pied flycatchers accumulated higher concentrations than great tits. > Cadmium and selenium accumulated with age in both species. - Accumulation of metals in liver of two insectivorous passerines reflects inter-specific differences in diet, absorption rate and physiological requirements.

    The breeding ecology of south temperate bird species is less widely known than that of north temperate species, yet because they comprise a large portion of the world's avian diversity, knowledge of their breeding ecology can contribute to a more comprehensive understanding of the geographic diversity of avian reproductive traits and life history strategies. We provide the first detailed examination of the reproductive strategies of 18 forest passerines of subtropical, northwestern Argentina. Mean clutch sizes were smaller and egg mass was greater than for north temperate birds, but differed among species and nest types, with cavity-nesters having larger clutches than species with open-cup and enclosed nests. Across all species, the average breeding season duration was 50 days; thus, the common perception that southern species have smaller clutch sizes because of longer breeding seasons is not supported in this community. Daily nest predation rates were influenced by nest type, cavity nests suffering the least from predation, as found in north temperate systems. Only females incubated eggs in all but one species, whereas both parents fed and cared for nestlings in all species. Mean nest attentiveness was low compared to north temperate passerines. Mean hourly nestling feeding rates differed among species and were negatively related to nest predation risk. In short, coexisting species in this subtropical forest varied in their life history strategies, in part correlated with variation in nest predation risk, but also differing from north temperate species. ??

    Within the presented study the SoilClim model was tested through various climatic and soil conditions. SoilClim model enables to estimate reference and actual evapotranspiration from defined vegetation cover and consequently the soil water content within two defined layers (named as Moisture control section I and II) could be deduced. The soil temperature in 0.5 m depth is also estimated (on the basis of simple empirical model). Mentioned outputs could be additionally used for identification of soil climate regimes (both Hydric and Thermic) within selected location. The SoilClim works in daily step and needs daily maximum and minimum air temperature, global radiation, precipitation, air humidity and wind speed as input. The brief information about soil layers (field capacity, wilting point, depth) and vegetation cover is necessary. The algorithm for reference evapotranspiration is based on Penman-Monteith method. The main aim of the study was to assess accuracy and suitability of the SoilClim for simulation of soil water content in the two defined layers and temperature in 0.50 m depth. For this purpose the seven stations through central U.S. were selected (by twos from Nebraska, Iowa and Kansas and one from South Dakota). Used measurements were observed from 2004 to 2008. The central European region was represented by Austrian Lysimetric station Gross-Enzersdorf. The data within three different soil profiles and for various crop covers (spring barley, winter wheat, maize and potato) from 1999 to 2004 were used. During introduced reserch SoilClim provided reasonable results of soil moisture for both layers against lysimetric measurements. Agreement between measured and estimated water content (30 days averages) could be described by coefficient of determination (R2) which varied from 0.45 to 0.75. The Mean Bias Error (MBE) for values in daily step was from -12.87 % to 20.66 % and Root Mean Square Error (RMSE) varied from 14.49 % to 34.76 %. The modeling efficiency

  4. Using Genealogical Mapping and Genetic Neighborhood Sizes to Quantify Dispersal Distances in the Neotropical Passerine, the Black-Capped Vireo.

    Full Text Available Dispersal is a key demographic process, ultimately responsible for genetic connectivity among populations. Despite its importance, quantifying dispersal within and between populations has proven difficult for many taxa. Even in passerines, which are among the most intensely studied, individual movement and its relation to gene flow remains poorly understood. In this study we used two parallel genetic approaches to quantify natal dispersal distances in a Neotropical migratory passerine, the black-capped vireo. First, we employed a strategy of sampling evenly across the landscape coupled with parentage assignment to map the genealogical relationships of individuals across the landscape, and estimate dispersal distances; next, we calculated Wright's neighborhood size to estimate gene dispersal distances. We found that a high percentage of captured individuals were assigned at short distances within the natal population, and males were assigned to the natal population more often than females, confirming sex-biased dispersal. Parentage-based dispersal estimates averaged 2400m, whereas gene dispersal estimates indicated dispersal distances ranging from 1600-4200 m. Our study was successful in quantifying natal dispersal distances, linking individual movement to gene dispersal distances, while also providing a detailed look into the dispersal biology of Neotropical passerines. The high-resolution information was obtained with much reduced effort (sampling only 20% of breeding population compared to mark-resight approaches, demonstrating the potential applicability of parentage-based approaches for quantifying dispersal in other vagile passerine species.

    Small passerines, sometimes referred to as perching birds or songbirds, are the most abundant bird group in the United States (US) and Canada, and the most common among bird fatalities caused by collision with turbines at wind energy facilities. We used data compiled from 39 studies conducted in the US and Canada to estimate the annual rate of small-bird fatalities. It was necessary for us to calculate estimates of small-bird fatality rates from reported all-bird rates for 30% of studies. The remaining 70% of studies provided data on small-bird fatalities. We then adjusted estimates to account for detection bias and loss of carcasses from scavenging. These studies represented about 15% of current operating capacity (megawatts [MW]) for all wind energy facilities in the US and Canada and provided information on 4,975 bird fatalities, of which we estimated 62.5% were small passerines comprising 156 species. For all wind energy facilities currently in operation, we estimated that about 134,000 to 230,000 small-passerine fatalities from collision with wind turbines occur annually, or 2.10 to 3.35 small birds/MW of installed capacity. When adjusted for species composition, this indicates that about 368,000 fatalities for all bird species are caused annually by collisions with wind turbines. Other human-related sources of bird deaths, (e.g., communication towers, buildings [including windows]), and domestic cats) have been estimated to kill millions to billions of birds each year. Compared to continent-wide population estimates, the cumulative mortality rate per year by species was highest for black-throated blue warbler and tree swallow; 0.043% of the entire population of each species was estimated to annually suffer mortality from collisions with turbines. For the eighteen species with the next highest values, this estimate ranged from 0.008% to 0.038%, much lower than rates attributed to collisions with communication towers (1.2% to 9.0% for top twenty species).

    Many vertebrates use colour vision for vital behaviour but their visual performance in dim light is largely unknown. The light intensity threshold of colour vision is known only for humans, horses and two parrot species. Here, we first explore this threshold in a passerine bird, the blue tit (Cyanistes caeruleus). Using classic conditioning of colour cues to food rewards in three individuals, we find a threshold ranging from 0.05 to 0.2 cd m(-2). Results are comparable to the two previously tested bird species. For tits, nest light conditions probably exceed that threshold, at least after sunrise. These results shed new light on the lively debate questioning the visual performance of cavity nesters and the evolutionary significance of egg and chick coloration. Although this needs further investigation, it is possible that blue tits exploit both colour and brightness cues when viewing their eggs, chicks or conspecifics in their nests.

    The neuropeptide GnRH-I is critical for the regulation of reproduction in all vertebrates. Study of the regulation of GnRH-I in passerine songbirds has been the focus of studies on subjects as diverse as photoperiodism, puberty, stress, nutrition, processing of auditory information, migration, global climate change, and evolutionary biology. Until now, analysis of GnRH-I in songbirds has been limited to measurement of immunoreactive peptide. Measurement of mRNA regulation has been impossible because of lack of knowledge of the GnRH gene sequence, despite many attempts in the last 20 years to identify it. Thus, the relative roles of environmental, social, physiological, and evolutionary influences upon passerine GnRH regulation have remained enigmatic. Here, we report the first cloning of GnRH-I cDNA from a songbird, Taeniopygia guttata, its localization and regulation. Although the homology of its translated precursor polypeptide between chicken GnRH-I precursor polypeptide was only 54%, zebra finch GnRH-I precursor contained an amino acid sequence that can be processed into chicken GnRH-I peptide (pEHWSYGLQPG-amide). In situ hybridization combined with immunocytochemistry showed co-localization of GnRH-I mRNA and immunoreactive peptide in the preoptic area of sexually mature birds. GnRH-I mRNA signal was greatly reduced in sexually immature birds. Ovary mass of female birds was positively correlated with GnRH-I mRNA level in the brain. These data will now permit molecular analysis of the regulation of songbird reproduction by physical, social, and physiological cues, along with fine scale analysis of selection pressures acting upon the reproductive system of songbirds.

    2009-08-01

    Full Text Available The European Council occupies a central role in European politics. Yet it is not officially accountable to any public or parliamentary body for the decisions it makes on behalf of European citizens. National parliaments are only entitled to exert control over their own Heads of Government or State. The European Parliament, as a supranational institution, is the only parliamentary body that regularly discusses European politics with the European Council as a collective, namely via the European Council Presidency. As such, it alone has the possibility to hold the Council accountable for the agreements made at European Summits. However, the European Parliament has limited rights to impose pressure on the European Council Presidency. Nonetheless, despite the lack of a formal accountability arrangement, the European Council Presidency is more forthcoming than could have been expected.

    This report presents the proceedings of a workshop held in Constanta, Romania on 22 May 2014. During the workshop, representatives from 18 Central and Eastern European countries gave oral presentations on the current oral health of children and young adults aged 16 years and younger. The aim of the workshop was to collect and present data relating to the oral health of children from Central and Eastern European countries and to discuss them in the context of the political changes that have taken place over the last two decades and the recent economic crisis.The presenters had previously completed a series of questions on oral epidemiological studies, prevention of oral disease, treatment and payment, dental personnel, uptake of oral health care and other considerations and structured their presentations on these topics plus the influence of the economic crisis on oral health. It should be remembered that this paper is a report of the proceedings of a workshop and not a study. Ethics approval is not required for workshops.After the 18 oral presentations a 90 min discussion took place during which further points were raised. The presentations, the discussion and the conclusions which were reached are reported in this manuscript.

  13. Central obesity and risk for type 2 diabetes in Maori, Pacific and European young men in New Zealand. Highlights and achievements

    International Nuclear Information System (INIS)

    Weight gain is associated with the incidence of Type 2 diabetes. Maori and Pacific people in New Zealand have a greater prevalence of obesity and Type 2 diabetes compared to NZ European people. We hypothesised that this difference is related to metabolic and fat distribution differences as previously demonstrated in a study of Polynesian and European women. Thirty healthy male volunteers between the ages of 18 and 27 years were selected for a wide range of fatness. Equal numbers, 10 in each group, self-identified as belonging to either the Maori, Pacific or European ethnic groups. Specific measurements undertaken included resting metabolic rate by indirect calorimetry; total energy expenditure over 14 days by the doubly-labelled water technique; total and regional body fat from dual-energy x-ray absorptiometry; anthropornetry (body mass index, skinfold thicknesses and girths); fat and carbohydrate utilisation from respiratory quotients and from carbon-13 analysis of expired breath; and dietary intake of macronutrients. Glucose tolerance, insulin, glycosylated haemoglobin, thyroid hormone, leptin and blood lipid determinations were also performed and HOMA and ISIO-120 indices calculated

  18. Migratory status is not related to the susceptibility to HPAIV H5N1 in an insectivorous passerine species.

    Directory of Open Access Journals (Sweden)

    Donata Kalthoff

    Full Text Available Migratory birds have evolved elaborate physiological adaptations to travelling, the implications for their susceptibility to avian influenza are however unknown. Three groups of stonechats (Saxicola torquata from (I strongly migrating, (II weakly migrating and (III non-migrating populations were experimentally infected with HPAIV H5N1. The different bird groups of this insectivorous passerine species were infected in autumn, when the migrating populations clearly exhibit migratory restlessness. Following infection, all animals succumbed to the disease from 3 through 7 days post inoculation. Viral shedding, antigen distribution in tissues, and survival time did not differ between the three populations. However, notably, endothelial tropism of the HPAIV infection was exclusively seen in the group of resident birds. In conclusion, our data document for the first time the high susceptibility of an insectivorous passerine species to H5N1 infection, and the epidemiological role of these passerine birds is probably limited due to their high sensitivity to HPAIV H5N1 infection. Despite pronounced inherited differences in migratory status, the groups were generally indistinguishable in their susceptibility, survival time, clinical symptoms and viral shedding. Nevertheless, the migratory status partly influenced pathogenesis in the way of viral tropism.

    The microanatomy of healthy beaks and claws in passerine birds has not been well described in the literature, despite the importance of these structures in avian life. Histological processing of hard-cornified tissues is notoriously challenging and only a few reports on effective techniques have been published. An emerging epizootic of beak deformities among wild birds in Alaska and the Pacific Northwest region of North America recently highlighted the need for additional baseline information about avian hard-cornified structures. In this study, we examine the beak and claw of the Black-capped Chickadee (Poecile atricapillus), a common North American passerine that is affected by what has been described as “avian keratin disorder.” We use light and scanning electron microscopy and high-magnification radiography to document the healthy microanatomy of these tissues and identify features of functional importance. We also describe detailed methods for histological processing of avian hard-cornified structures and discuss the utility of special stains. Results from this study will assist in future research on the functional anatomy and pathology of hard-cornified structures and will provide a necessary reference for ongoing investigations of avian keratin disorder in Black-capped Chickadees and other wild passerine species.

    We studied food habits of Gyrfalcons (Falco rusticolus) nesting in central west Greenland in 2000 and 2001 using three sources of data: time-lapse video (3 nests), prey remains (22 nests), and regurgitated pellets (19 nests). These sources provided different information describing the diet during the nesting period. Gyrfalcons relied heavily on Rock Ptarmigan (Lagopus mutus) and arctic hares (Lepus arcticus). Combined, these species contributed 79-91% of the total diet, depending on the data used. Passerines were the third most important group. Prey less common in the diet included waterfowl, arctic fox pups (Alopex lagopus), shorebirds, gulls, alcids, and falcons. All Rock Ptarmigan were adults, and all but one arctic hare were young of the year. Most passerines were fledglings. We observed two diet shifts, first from a preponderance of ptarmigan to hares in mid-June, and second to passerines in late June. The video-monitored Gyrfalcons consumed 94-110 kg of food per nest during the nestling period, higher than previously estimated. Using a combination of video, prey remains, and pellets was important to accurately document Gyrfalcon diet, and we strongly recommend using time-lapse video in future diet studies to identify biases in prey remains and pellet data.

    Political theory of European union, through an engagement between political concepts and theoretical understandings, provides a means of identifying the EU as a political object. It is argued that understanding the projects, processes and products of European union, based on ‘sharing’ or ‘communion......’, provides a better means of perceiving the EU as a political object rather than terms such as ‘integration’ or ‘co-operation’. The concept of ‘European communion’ is defined as the ‘subjective sharing of relationships’, understood as the extent to which individuals or groups believe themselves to be sharing...... relations (or not), and the consequences of these beliefs for European political projects, processes and products. By exploring European communion through an engagement with contemporary political theory, using very brief illustrations from the Treaty of Lisbon, the article also suggests that European...

  4. A satellite-based climatology (1989-2012) of lake surface water temperature from AVHRR 1-km for Central European water bodies

    2013-04-01

    The temperature of lakes is an important parameter for lake ecosystems influencing the speed of physio-chemical reactions, the concentration of dissolved gazes (e.g. oxygen), and vertical mixing. Even small temperature changes might have irreversible effects on the lacustrine system due to the high specific heat capacity of water. These effects could alter the quality of lake water depending on parameters like lake size and volume. Numerous studies mention lake water temperature as an indicator of climate change and in the Global Climate Observing System (GCOS) requirements it is listed as an essential climate variable. In contrast to in situ observations, satellite imagery offers the possibility to derive spatial patterns of lake surface water temperature (LSWT) and their variability. Moreover, although for some European lakes long in situ time series are available, the temperatures of many lakes are not measured or only on a non-regular basis making these observations insufficient for climate monitoring. However, only few satellite sensors offer the possibility to analyze time series which cover more than 20 years. The Advanced Very High Resolution Radiometer (AVHRR) is among these and has been flown on the National Oceanic and Atmospheric Administration (NOAA) Polar Operational Environmental Satellites (POES) and on the Meteorological Operational Satellites (MetOp) from the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) as a heritage instrument for almost 35 years. It will be carried on for at least ten more years finally offering a unique opportunity for satellite-based climate studies. Herein we present the results from a study initiated by the Swiss GCOS office to generate a satellite-based LSWT climatology for the pre-alpine water bodies in Switzerland. It relies on the extensive AVHRR 1-km data record (1985-2012) of the Remote Sensing Research Group at the University of Bern (RSGB) and has been derived from the AVHRR/2

    Full Text Available This paper presents the list of non-passerine birds of coastal environments of the Quissama municipality, northern Rio de Janeiro State, southeastern Brazil. The surveys were conducted monthly between June 2011 and May 2012. Additional ad libitum observations were made between February 2008 and July 2012. We recorded 76 waterbird species of 15 families, of which Scolopacidae was the most representative, with 15 species. The high Nearctic shorebird species richness observed in coastal lagoons in Quissama (17 species is an evidence of the important role of the region as staging site for migratory birds at national level. Also, nine of the species recorded are threatened at regional and one is threatened at national level. It should be emphasized that three species considered locally extinct in the municipality of Rio de Janeiro, the most extensively surveyed area in the State, were recorded in the present study. Additionally, we present a high number of previously unrecorded species in northern Rio de Janeiro, and report the first documented record of Stercorarius pomarinus in Rio de Janeiro State. The region has a notorious Waterbird richness including endangered and migratory species, when compared to other coastal areas of the state.

  6. No evidence for pre-copulatory sexual selection on sperm length in a passerine bird.

    Directory of Open Access Journals (Sweden)

    Jan T Lifjeld

    Full Text Available There is growing evidence that post-copulatory sexual selection, mediated by sperm competition, influences the evolution of sperm phenotypes. Evidence for pre-copulatory sexual selection effects on sperm traits, on the other hand, is rather scarce. A recent paper on the pied flycatcher, Ficedula hypoleuca, reported phenotypic associations between sperm length and two sexually selected male traits, i.e. plumage colour and arrival date, thus invoking pre-copulatory sexual selection for longer sperm. We were unable to replicate these associations with a larger data set from the same and two additional study populations; sperm length was not significantly related to either male plumage colour or arrival date. Furthermore, there was no significant difference in sperm length between populations despite marked differences in male plumage colour. We also found some evidence against the previously held assumption of longer sperm being qualitatively superior; longer sperm swam at the same speed as shorter sperm, but were less able to maintain speed over time. We argue that both empirical evidence and theoretical considerations suggest that the evolution of sperm morphology is not primarily associated with pre-copulatory sexual selection on male secondary sexual traits in this or other passerine bird species. The relatively large between-male variation in sperm length in this species is probably due to relaxed post-copulatory sexual selection.

    Ultraviolet (UV) light-transmitted signals play a major role in avian foraging and communication, subserving functional roles in feeding, mate choice, egg recognition, and nestling discrimination. Sequencing functionally relevant regions of the short wavelength sensitive type 1 (SWS1) opsin gene that is responsible for modulating the extent of SWS1 UV sensitivity in birds allows predictions to be made about the visual system's UV sensitivity in species where direct physiological or behavioral measures would be impractical or unethical. Here, we present SWS1 segment sequence data from representative species of three avian lineages for which visually based cues for foraging and communication have been investigated to varying extents. We also present a preliminary phylogenetic analysis and ancestral character state reconstructions of key spectral tuning sites along the SWS1 opsin based on our sequence data. The results suggest ubiquitous ultraviolet SWS1 sensitivity (UVS) in both paleognaths, including extinct moa (Emeidae), and parrots, including the nocturnal and flightless kakapo (Strigops habroptilus), and in most, but not all, songbird (oscine) lineages, and confirmed violet sensitivity (VS) in two suboscine families. Passerine hosts of avian brood parasites were included both UVS and VS taxa, but sensitivity did not co-vary with egg rejection behaviors. The results should stimulate future research into the functional parallels between the roles of visual signals and the genetic basis of visual sensitivity in birds and other taxa.

    Avian trichomonosis, caused by the flagellated protozoan Trichomonas gallinae, is a recently emerged infectious disease of British passerines. The aetiological agent, a clonal epidemic strain of the parasite, has caused unprecedented finch mortality and population-level declines in Britain and has since spread to continental Europe. To better understand the potential origin of this epidemic and to further investigate its host range, T. gallinae DNA extracts were collected from parasite culture and tissue samples from a range of avian species in Britain. Sequence typing at the ITS1/5.8S rRNA/ITS2 region resolved three distinct ITS region types circulating in free-ranging British birds. Subtyping by sequence analyses at the Fe-hydrogenase gene demonstrated further strain variation within these ITS region types. The UK finch epidemic strain was preponderant amongst columbids sampled, however, wide strain diversity was encountered in isolates from a relatively small number of pigeons, suggesting further strains present in columbid populations across the UK are yet to be identified. Fe-hydrogenase gene sequence data in isolates from birds of prey with disease were predominantly identical to the UK finch epidemic strain, demonstrating its presence as a virulent strain in UK birds of prey since at least 2009.

    Technological advances in industrial processes have resulted in reduced atmospheric emissions from metal industries all over the globe, but the response of the environment is not well known. The authors studied metal (As, Cd, Cu, Ni, Pb, and Se) accumulation in passerine birds (pied flycatcher, Ficedula hypoleuca, and great tit, Parus major) following almost 20 years of reduced metal emissions from the largest nonferrous smelter in Finland. Close to the industry, emission reductions resulted in reduced exposure to several of the elements and, more importantly, reduced accumulation by 58 to 95% in liver tissue. Albeit showing significant tissue reductions, nestlings had elevated concentrations of arsenic, cadmium, lead, and selenium close to the industry. Single-element concentrations were below critical levels associated with subclinical effects, but the mixture of toxic elements indirectly affected health and reproduction. Our study indicates that in environments with moderate duration of industrial activity, impact, and soil pollution, metal accumulation in organisms can decrease relatively rapidly when atmospheric emissions are reduced.

    Haemosporidian parasites infecting birds show distinct heterogeneity in their distribution among host species. However, despite numerous studies on the prevalence and diversity of parasite communities across species, very little is known on patterns of differences between them. Such data is lacking because up to date the majority of studies explored the patterns of variation in infections in different years, different time of sampling within a year or a breeding cycle, different study sites or was based on a small sample size, all of which may affect the estimates of prevalence and parasite diversity. Here, the prevalence, richness and diversity of haemosporidian parasites from the genera Plasmodium and Haemoproteus were studied in two closely related non-migratory hole-nesting passerines: Great Tits and Blue Tits. Birds were sampled in sympatrically breeding populations during two seasons at the same stage of their breeding cycle - late nestling care. Great Tits were more prevalently infected with Plasmodium and Haemoproteus parasites (97·1 vs 71·2%), harboured a higher proportion of multiple infections (26·2 vs 3·2%) and had a more diverse parasite community (11 vs 5 parasite lineages) than Blue Tits. Observed differences between two host species are discussed with reference to their breeding densities and immunological and behavioural characteristics. PMID:27173618

    The boundary between the Rheno-Hercynian and the Saxo-Thuringian zones of the European Variscides is characterized by a NE-SW striking late orogenic fold-and-thrust belt affecting the intervening Rheic suture. Classical models used the first-order strike of this zone as an indicator for perpendicular plate convergence, i.e. NW-SE. We present structural data from both sides of the suture, focusing on fold-cleavage relationships. The statistical analysis reveals an orientation maximum of the youngest cleavage that deviates from the strike of the fold-and-thrust belt by c. 22°. The presence of clockwise transection of the folds by the cleavage (up to - 16°) indicates pervasive sinistral transpression. Three types of fold-cleavage relationships are observed: NE trending folds (I) with or (II) without a transecting cleavage, and (III) non-transected ENE trending folds. We explain the occurrence of different fold-cleavage types by strain partitioning due to NNW convergence obliquely to pre-existent NE trending mechanical anisotropies. In terms of plate tectonics we propose that the classical boundary of the Rheno-Hercynian and the Saxo-Thuringian Zone represents an initial transform plate boundary that was finally affected by sinistral transpression.

    Heavy precipitation affected Central Europe in May/June 2013, triggering damaging floods both on the Danube and the Elbe rivers. A modelling approach with COSMO-CLM is used for a detailed analysis of the evolution of the event. Moisture flux, backward trajectories, evaporation and cyclone track analysis are evaluated for the relevant time period 30 May to 2 June 2013. The aim is to identify potential moisture sources and to quantify their contribution to the flood event in the Danube basin. Control simulations with undisturbed ERA-Interim boundary conditions and sensitivity experiments with modified evaporation characteristics are performed to estimate the role of moisture evaporated from different marine and land areas. The simulated cyclone tracks and upper level flow are compared against reanalysis. Simulated precipitation amounts are validated against E-OBS precipitation data. Two relevant cyclones are identified, which moved counterclockwise in a retrograde path from Southeastern Europe over Eastern Europe towards the northern slopes of the Alps. The control simulations represent the cyclone characteristics and tracks reasonably well. The evolution of the precipitation event in the simulations shows some minor differences to the Reanalysis in terms of its spatial and temporal characteristics. Our sensitivity experiment results provide evidence that the two main sources contributing to the event were the continental evapotranspiration (moisture recycling) and the North Atlantic Ocean. The Mediterranean Sea played only a minor role as a moisture source. This study confirms the importance of continental moisture recycling for heavy precipitation events over Central Europe during the summer half year.

    Central Europe, the focus region of this study, is a region in transition, climatically from maritime to continental and politically from formerly more planning-oriented to more market-oriented management regimes, and in terms of climate change from regions of increasing precipitation in the west and north of Europe to regions of decreasing precipitation in central and southern Europe. The Elbe basin, a trans-boundary catchment flowing from the Czech Republic through Germany into the North Sea, was selected to investigate the possible impacts of global change on crop yields and water resources in this region. For technical reasons, the paper has been split into two parts, the first showing the overall model concept, the model set-up for the agricultural sector, and first results linking eco-hydrological and agro-economic tools for the German part of the basin. The second part describes the model set-up for simulating water supply and demand linking eco-hydrological and water management tools for the entire basin including the Czech part.

  19. Effect of Climate Change on Mediterranean Winter Ranges of Two Migratory Passerines.

    Full Text Available We studied the effect of climate change on the distribution of two insectivorous passerines (the meadow pipit Anthus pratensis and the chiffchaff Phylloscopus collybita in wintering grounds of the Western Mediterranean basin. In this region, precipitation and temperature can affect the distribution of these birds through direct (thermoregulation costs or indirect effects (primary productivity. Thus, it can be postulated that projected climate changes in the region will affect the extent and suitability of their wintering grounds. We studied pipit and chiffchaff abundance in several hundred localities along a belt crossing Spain and Morocco and assessed the effects of climate and other geographical and habitat predictors on bird distribution. Multivariate analyses reported a positive effect of temperature on the present distribution of the two species, with an additional effect of precipitation on the meadow pipit. These climate variables were used with Maxent to model the occurrence probabilities of species using ring recoveries as presence data. Abundance and occupancy of the two species in the study localities adjusted to the distribution models, with more birds in sectors of high climate suitability. After validation, these models were used to forecast the distribution of climate suitability according to climate projections for 2050-2070 (temperature increase and precipitation reduction. Results show an expansion of climatically suitable sectors into the highlands by the effect of warming on the two species, and a retreat of the meadow pipit from southern sectors related to rain reduction. The predicted patterns show a mean increase in climate suitability for the two species due to the warming of the large highland expanses typical of the western Mediterranean.

  20. The impact of an invasive exotic bush on the stopover ecology of migrant passerines

    Arizaga, J.

    2013-01-01

    Full Text Available Migration is highly energy-demanding and birds often need to accumulate large fuel loads during this period. However, original habitat at stopover sites could be affected by invasive exotic plants outcompeting native vegetation. The impact of exotic plants on the stopover behavior of migrant bird species is poorly understood. As a general hypothesis, it can be supposed that habitat change due to the presence of exotic plants will affect migrants, having a negative impact on bird abundance, on avian community assemblage, and/or on fuel deposition rate. To test these predictions, we used data obtained in August 2011 at a ringing station in a coastal wetland in northern Iberia which contained both unaltered reedbeds (Phragmites spp. and areas where the reedbeds had been largely replaced by the invasive saltbush (Baccharis halimifolia. Passerines associated with reedbeds during the migration period were used as model species, with a particular focus on sedge warblers (Acrocephalus schoenobaenus. The saltbush promoted a noticeable change on bird assemblage, which became enriched by species typical of woodland habitats. Sedge warblers departed with a higher fuel load, showed a higher fuel deposition rate, and stayed for longer in the control zone than in the invaded zone. Invasive plants, such as saltbush, can impose radical changes on habitat, having a direct effect on the stopover strategies of migrants. The substitution of reedbeds by saltbushes in several coastal marshes in Atlantic Europe should be regarded as a problem with potential negative cons equences for the conservation of migrant bird species associated with this habitat.

  1. Antioxidant defenses predict long-term survival in a passerine bird.

    Directory of Open Access Journals (Sweden)

    Nicola Saino

    Full Text Available BACKGROUND: Normal and pathological processes entail the production of oxidative substances that can damage biological molecules and harm physiological functions. Organisms have evolved complex mechanisms of antioxidant defense, and any imbalance between oxidative challenge and antioxidant protection can depress fitness components and accelerate senescence. While the role of oxidative stress in pathogenesis and aging has been studied intensively in humans and model animal species under laboratory conditions, there is a dearth of knowledge on its role in shaping life-histories of animals under natural selection regimes. Yet, given the pervasive nature and likely fitness consequences of oxidative damage, it can be expected that the need to secure efficient antioxidant protection is powerful in molding the evolutionary ecology of animals. Here, we test whether overall antioxidant defense varies with age and predicts long-term survival, using a wild population of a migratory passerine bird, the barn swallow (Hirundo rustica, as a model. METHODOLOGY/PRINCIPAL FINDINGS: Plasma antioxidant capacity (AOC of breeding individuals was measured using standard protocols and annual survival was monitored over five years (2006-2010 on a large sample of selection episodes. AOC did not covary with age in longitudinal analyses after discounting the effect of selection. AOC positively predicted annual survival independently of sex. Individuals were highly consistent in their relative levels of AOC, implying the existence of additive genetic variance and/or environmental (including early maternal components consistently acting through their lives. CONCLUSIONS: Using longitudinal data we showed that high levels of antioxidant protection positively predict long-term survival in a wild animal population. Present results are therefore novel in disclosing a role for antioxidant protection in determining survival under natural conditions, strongly demanding for more

    Climate change elevates conservation concerns worldwide because it is likely to exacerbate many identified threats to animal populations. In recent decades, grassland birds have declined faster than other North American bird species, a loss thought to be due to habitat loss and fragmentation and changing agricultural practices. Climate change poses additional threats of unknown magnitude to these already declining populations. We examined how seasonal and daily weather conditions over 10 years influenced nest survival of five species of insectivorous passerines native to the shortgrass prairie and evaluate our findings relative to future climate predictions for this region. Daily nest survival (n = 870) was best predicted by a combination of daily and seasonal weather variables, age of nest, time in season and bird habitat guild. Within a season, survival rates were lower on very hot days (temperatures ≥ 35 °C), on dry days (with a lag of 1 day) and on stormy days (especially for those species nesting in shorter vegetation). Across years, survival rates were also lower during warmer and drier breeding seasons. Clutch sizes were larger when early spring temperatures were cool and the week prior to egg-laying was wetter and warming. Climate change is likely to exacerbate grassland bird population declines because projected climate conditions include rising temperatures, more prolonged drought and more intense storms as the hydrological cycle is altered. Under varying realistic scenarios, nest success estimates were halved compared to their current average value when models both increased the temperature (3 °C) and decreased precipitation (two additional dry days during a nesting period), thus underscoring a sense of urgency in identifying and addressing the current causes of range-wide declines.

    Matrix land-use intensification is a relatively recent and novel landscape change that can have important influences on the biota within adjacent habitat patches. While there are immediate local changes that it brings about, the influences on individual animals occupying adjacent habitats may be less evident initially. High-intensity land use could induce chronic stress in individuals in nearby remnants, leading ultimately to population declines. We investigated how physiological indicators and body condition measures of tropical forest-dependent birds differ between forest adjacent to surface mining sites and that near farmlands at two distances from remnant edge in southwest Ghana. We used mixed effects models of several condition indices including residual body mass and heterophil to lymphocyte (H/L) ratios (an indicator of elevated chronic stress) to explore the effect of matrix intensity on forest-dependent passerines classed as either sedentary area-sensitive habitat specialists or nomadic generalists. Individual birds occupying tropical forest remnants near surface mining sites were in poorer condition, as indicated by lower residual body mass and elevated chronic stress, compared to those in remnants near agricultural lands. The condition of the sedentary forest habitat specialists white-tailed alethe, Alethe diademata and western olive sunbird, Cyanomitra obscura was most negatively affected by high-intensity surface mining land-use adjacent to remnants, whereas generalist species were not affected. Land use intensification may set in train a new trajectory of faunal relaxation beyond that expected based on habitat loss alone. Patterns of individual condition may be useful in identifying habitats where species population declines may occur before faunal relaxation has concluded. PMID:26107179

    Three reproductive trials were conducted to develop techniques for propagation of captive starlings (Stumus vulgaris) which could determine the effects of environmental contaminants on passerine reproduction. Trials were conducted during the spring of 1979 in five adjacent 2.4 by 3 by 12-m outdoor wire pens containing four or ten pairs of starlings, a similar number of nest boxes, perches, water, commercial turkey starter, and alfalfa hay as nesting material. Nestling diets consisted of combinations of Nebraska Brand bird of prey diet, live or frozen mealworms (Tenebrio molitor) and crickets (Acheta domestica), or live earthworms (Pheretima sp.). Starlings reproduced successfully when the number of breeding pairs per pen was reduced from ten to four. The average clutch sizes for each pen (4.3 to 4.9) were similar to those reported for wild starlings. Hatching (60 to 90.4 percent) and fledging (0 to 100 percent) success varied among pens. The fledging success was greatest in the pens which received the most diverse nestling diets: Nebraska Brand diet plus frozen or live mealworms and crickets. Whether the insects were presented alive or frozen appeared to have little effect on the reproductive success. The starlings did not consume or carry earthworms to their young. The body weights of 20-day-old nestlings raised in captivity (X=73.9 g) were similar to those of starlings in the wild. The use of single pairs per pen may eliminate problems in presentation of nestling diets due to asynchrony in breeding between pairs and excessive interactions among individuals, which may interfere with parental care. The starling appears to be an excellent model for examining the effects of environmental contaminants on the reproduction of songbirds in captivity.

    We studied the effect of climate change on the distribution of two insectivorous passerines (the meadow pipit Anthus pratensis and the chiffchaff Phylloscopus collybita) in wintering grounds of the Western Mediterranean basin. In this region, precipitation and temperature can affect the distribution of these birds through direct (thermoregulation costs) or indirect effects (primary productivity). Thus, it can be postulated that projected climate changes in the region will affect the extent and suitability of their wintering grounds. We studied pipit and chiffchaff abundance in several hundred localities along a belt crossing Spain and Morocco and assessed the effects of climate and other geographical and habitat predictors on bird distribution. Multivariate analyses reported a positive effect of temperature on the present distribution of the two species, with an additional effect of precipitation on the meadow pipit. These climate variables were used with Maxent to model the occurrence probabilities of species using ring recoveries as presence data. Abundance and occupancy of the two species in the study localities adjusted to the distribution models, with more birds in sectors of high climate suitability. After validation, these models were used to forecast the distribution of climate suitability according to climate projections for 2050–2070 (temperature increase and precipitation reduction). Results show an expansion of climatically suitable sectors into the highlands by the effect of warming on the two species, and a retreat of the meadow pipit from southern sectors related to rain reduction. The predicted patterns show a mean increase in climate suitability for the two species due to the warming of the large highland expanses typical of the western Mediterranean. PMID:26761791

  7. Variation in maternal effects and embryonic development rates among passerine species

    Martin, T.E.; Schwabl, H.

    2008-01-01

    Embryonic development rates are reflected by the length of incubation period in birds, and these vary substantially among species within and among geographical regions. The incubation periods are consistently shorter in North America (Arizona study site) than in tropical (Venezuela) and subtropical (Argentina) South America based on the study of 83 passerine species in 17 clades. Parents, mothers in particular, may influence incubation periods and resulting offspring quality through proximate pathways, while variation in maternal strategies among species can result from selection by adult and offspring mortality. Parents of long-lived species, as is common in the tropics and subtropics, may be under selection to minimize costs to themselves during incubation. Indeed, time spent incubating is often lower in the tropical and subtropical species than the related north temperate species, causing cooler average egg temperatures in the southern regions. Decreased egg temperatures result in longer incubation periods and reflect a cost imposed on offspring by parents because energy cost to the embryo and risk of offspring predation are both increased. Mothers may adjust egg size and constituents as a means to partially offset such costs. For example, reduced androgen concentrations in egg yolks may slow development rates, but may enhance offspring quality through physiological trade-offs that may be particularly beneficial in longer-lived species, as in the tropics and subtropics. We provide initial data to show that yolks of tropical birds contain substantially lower concentrations of growth-promoting androgens than north temperate relatives. Thus, maternal (and parental) effects on embryonic development rates may include contrasting and complementary proximate influences on offspring quality and deserve further field study among species. ?? 2007 The Royal Society.

  8. Genetic covariance between indices of body condition and immunocompetence in a passerine bird

    2005-11-01

    Full Text Available Abstract Background Condition-dependence is a ubiquitous feature of animal life histories and has important implications for both natural and sexual selection. Mate choice, for instance, is typically based on condition-dependent signals. Theory predicts that one reason why condition-dependent signals may be special is that they allow females to scan for genes that confer high parasite resistance. Such explanations require a genetic link between immunocompetence and body condition, but existing evidence is limited to phenotypic associations. It remains unknown, therefore, whether females selecting males with good body condition simply obtain a healthy mate, or if they acquire genes for their offspring that confer high immunocompetence. Results Here we use a cross-foster experimental design to partition the phenotypic covariance in indices of body condition and immunocompetence into genetic, maternal and environmental effects in a passerine bird, the zebra finch Taeniopygia guttata. We show that there is significant positive additive genetic covariance between an index of body condition and an index of cell-mediated immune response. In this case, genetic variance in the index of immune response explained 56% of the additive genetic variance in the index of body condition. Conclusion Our results suggest that, in the context of sexual selection, females that assess males on the basis of condition-dependent signals may gain genes that confer high immunocompetence for their offspring. More generally, a genetic correlation between indices of body condition and imuunocompetence supports the hypothesis that parasite resistance may be an important target of natural selection. Additional work is now required to test whether genetic covariance exists among other aspects of both condition and immunocompetence.

  9. Passerine migrant stopover duration and spatial behaviour at an urban stopover site

    2010-09-01

    Migration routes of many Nearctic-Neotropical landbirds pass through the most urbanized regions of North America. Migrants are known to use urban habitats as stopover sites and often occur in cities at exceptional density; yet knowledge of migrant behaviour and ecology in such places is surprisingly limited. We radio-tracked ovenbirds ( Seiurus aurocapillus) during stopovers in a New York City park to obtain some of the first detailed information on how landbird migrants utilize an urban habitat as a stopover site. We examined fine-scale movement patterns, home range sizes, stopover durations, and how arrival condition affected each of these metrics. During both seasons, most birds moved widely throughout the site upon presumed arrival and then either continued migration that night or settled into a more defined area on subsequent days. Area usage varied markedly among individuals during both seasons, ranging 1-16 ha. Stopover durations averaged 3.0 days (range = 1-10 days) during spring and 2.9 days (range = 1-14 days) during autumn. Spatial behaviours and stopover durations were not influenced by arrival condition during spring, and during autumn only movement rates and displacement distances were significantly (negatively) condition-related. Our findings do not support previous assumptions that urban stopover habitats are only used by migrants briefly in times of urgency when alternatives are unavailable. At least half of the birds we studied stopped over for multiple days during both seasons, and bird movements were indicative of an ability to search for, locate, and occupy suitable micro-sites. Ovenbird behaviour in our study site was similar in many ways to what has been observed in recent telemetry studies of ovenbirds and other passerine migrants at various non-urban stopover sites.

    Avian blood parasites have been preliminarily studied in East Asia, but no data are available from long-term monitoring. The aim of this study was to evaluate the prevalence, genetic diversity, and temporal dynamics of Plasmodium, Haemoproteus, and Leucocytozoon in two passerine communities (one forest and one urban) in north China from 2008 to 2013, as well as the association between infected lineages and host specificities. Out of 633 birds from 40 species, 157 individuals (24.8 %) were infected; overall prevalence was 26.7 % and 16.8 % in two sites, respectively. The dominant avian blood parasite genus in the forest park changed yearly between Plasmodium and Haemoproteus, while the Leucocytozoon maintained a low infection level. Forty-four haplotypes were identified by sequencing a 432-bp fragment of the cytochrome b (cyt b) gene; more than 70 % were novel (six Plasmodium lineages, 16 Haemoproteus lineages, and nine Leucocytozoon lineages). Based on our data gathered over consecutive years, we found that the highly observed lineages of Haemoproteus showed higher host diversities than those of Plasmodium, and the most infected lineage EMEL01 (100 % identity with SGS1) take on the highest host diversity but low temporal diversity of the two genera, implying that this lineage infected a great diversity of species in certain years, but maintained a lower infection level or even disappeared in other years. The results suggest that genetic diversity of avian blood parasites in East Asia is high and provides scope for further research. In addition, compared with overall analysis, yearly prevalence monitoring is important in uncovering the temporal dynamic and host specificity variations over time.

  11. Matrix Intensification Affects Body and Physiological Condition of Tropical Forest-Dependent Passerines.

    Directory of Open Access Journals (Sweden)

    Justus P Deikumah

    Full Text Available Matrix land-use intensification is a relatively recent and novel landscape change that can have important influences on the biota within adjacent habitat patches. While there are immediate local changes that it brings about, the influences on individual animals occupying adjacent habitats may be less evident initially. High-intensity land use could induce chronic stress in individuals in nearby remnants, leading ultimately to population declines. We investigated how physiological indicators and body condition measures of tropical forest-dependent birds differ between forest adjacent to surface mining sites and that near farmlands at two distances from remnant edge in southwest Ghana. We used mixed effects models of several condition indices including residual body mass and heterophil to lymphocyte (H/L ratios (an indicator of elevated chronic stress to explore the effect of matrix intensity on forest-dependent passerines classed as either sedentary area-sensitive habitat specialists or nomadic generalists. Individual birds occupying tropical forest remnants near surface mining sites were in poorer condition, as indicated by lower residual body mass and elevated chronic stress, compared to those in remnants near agricultural lands. The condition of the sedentary forest habitat specialists white-tailed alethe, Alethe diademata and western olive sunbird, Cyanomitra obscura was most negatively affected by high-intensity surface mining land-use adjacent to remnants, whereas generalist species were not affected. Land use intensification may set in train a new trajectory of faunal relaxation beyond that expected based on habitat loss alone. Patterns of individual condition may be useful in identifying habitats where species population declines may occur before faunal relaxation has concluded.

    The European Community was established in 1951 to reconcile France and Germany after World War II and to make possible the eventual federation of Europe. By 1986, there were 12 member countries: France, Italy, Belgium, the Federal Republic of Germany, Luxembourg, the Netherlands, Denmark, Ireland, the United Kingdom, Greece, Spain, and Portugal. Principal areas of concern are internal and external trade, agriculture, monetary coordination, fisheries, common industrial and commercial policies, assistance, science and research, and common social and regional policies. The European Community has a budget of US$34.035 billion/year, funded by customs duties and 1.4% of each member's value-added tax. The treaties establishing the European Community call for members to form a common market, a common customs tariff, and common agricultural, transport, economic, and nuclear policies. Major European Community institutions include the Commission, Council of Ministers, European Parliament, Court of Justice, and Economic and Social Committee. The Community is the world's largest trading unit, accounting for 15% of world trade. The 2 main goals of the Community's industrial policy are to create an open internal market and to promote technological innovation in order to improve international competitiveness. The European Community aims to contribute to the economic and social development of Third World countries as well. PMID:12177941

  14. Estimating the tritium input to groundwater from wine samples: Groundwater and direct run-off contribution to Central European surface waters

    International Nuclear Information System (INIS)

    A model is derived which allows a quantitative evaluation of wine tritium data. It is shown that the tritium content of a wine sample is not determined exclusively by water taken up by the roots, but is also influenced to a large extent by direct exchange with atmospheric moisture. The soil-water fraction amounts normally to not more than 40%. Thus, wine is a sample partly of atmospheric moisture at ground level, partly of soil moisture, integrated over a period around three weeks before vintage. The tritium content of two sets of wine samples originating from two selected sites in the Federal Republic of Germany and dating back to 1949 is reported. For the period since records of the tritium content of rain in Europe have become available comparisons of wine tritium with reported tritium activities of rain are in favour of the model outlined. The first distinguishable influence of bomb tritium shows up in the 1953 wine, whilst no detectable response to Castle tritium is found in 1954. By comparison with recorded rain activities at Ottawa, Canada, it is concluded that Castle influenced the tritium fall-out in Central Europe much less than it did at Ottawa. For the period before 1955 the tritium activity of the annual groundwater recharge, including pre-thermonuclear recharge in Central Europe, is estimated from the wine data. An estimation of the total assimilation of pre-thermonuclear tritium into the ocean at 50 degrees N is also given, which points to a value of 1-1.5 atoms/cm2 s. It is shown that in further uses of pre-thermonuclear wines the possibility that samples have been contaminated by penetration of thermonuclear tritium through the bottle seals must be considered. The estimates of the tritium activities of groundwater recharge are based on the fact that in our climate the main contribution to groundwater is made up by autumn and winter precipitation. Because of this correlation with season the groundwater recharge is much lower in tritium than the

  16. The strong diachronous Muschelkalk/Keuper facies shift in the Central European Basin: implications from the type-section of the Erfurt Formation (Lower Keuper, Triassic) and basin-wide correlations

    The transition from the shallow marine Upper Muschelkalk Sea to the Lower Keuper fluvial plain represents the most diachronous facies shift of the entire Germanic Triassic. The type-section of the fluvial Lower Keuper (Erfurt Formation) is described in detail for the first time including biostratigraphic dating of the Muschelkalk/Keuper boundary. The type-section is integrated into a NNE-SSW cross section through the Central European Basin, and the Muschelkalk/Keuper facies shift is constrained by high-resolution conodont and ceratite biostratigraphy. Thus, the fundamental changes in palaeogeography, shifts of facies belts and stratal pattern architecture are visualised. Forced by a rapid transgression from Tethyan waters, the shallow marine Upper Muschelkalk Sea attained its maximum flooding in the lower conodont zone 2 ( sequens/pulcher to philippi/robustus zones). Subsequent slow continuous regression to the South was accompanied by step-by-step progradation of coastal to fluvial plain environments of the Lower Keuper, culminating in a fluvial plain extending to South Germany. Based on stratal patterns, an improved sequence-stratigraphic interpretation for the Upper Muschelkalk/Lower Keuper interval is suggested. In combination with biostratigraphic arguments, the new sequence-stratigraphy points to a revised correlation of this interval within the Tethyan Triassic, incorporating the positions of the Anisian/Ladinian and Fassanian/Longobardian boundaries.

    European military transfusion services follow operational guidelines established by their respective national health systems and conform with European Union directives and NATO standards as applicable to member countries. Certain features are common to all of these standards, especially the pre-selection of volunteer, almost exclusively unpaid donors. NATO requirements are very close to European guidelines, with the exception that NATO permits the use of blood products collected in emergency conditions in theater when circumstances allow no better option. Blood product traceability exists for every country but is not always centralized or computerized. Serious adverse event reporting relies on national haemovigilance networks. Military considerations become important mainly in overseas operations, where the overall policy is to implement the relevant national, European or NATO guidelines with adjustments made for unique wartime circumstances and the risk/benefit ratio for the individual patient needing a transfusion.

The newly emerged circumstances, each EU member state has its own regionalization, there is no defined standard for a particular region, but in the final stages of the integration of the whole region covers an area located within the boundaries of several other states. The integration process is achieved through macro or cross-border regions that have a European statute, cross-border cooperation includes new rules of economic and social cohesion of the regions making autonomy. There is the problem of the division of responsibilities at Union or Member State or lower levels of government which is not defined in the Treaty of Lisbon, but the Committee of the Regions assigned tasks in cooperation with the EU institutions to take account of respect for the principle of subsidiarity. The effect of European integration is reflected in the delegation of authority to supranational levels and means the performance of a growing number of jobs by the interregional group.

    Full Text Available In July 1997 the Commission of the European Union presented its Agenda 2000. This document not only suggested to start accession talks with some East and Central European countries (CEEC in early 1998 but it also provided proposals for a restructuring of EU expenditures. On this background this contribution discusses the state of readiness of the Central and East European countries to become EU members over the next few years and the Union's capacity to absorb up to ten CEEC over the next decade or so. This study concludes that the European Union has become an anchor of stability to the CEEC that guarantees both democracy and economic security--much more than could be expected only a couple of years ago. The Union's readiness to accept the membership of CEEC has, in a decisive way, contributed to their societal, political and economic stabilization. There is almost a contest among the CEEC on which one is going to meet the accession criteria first and best. The enlargement process, however, is connected to problems the resolution of which realistically postpone its successful conclusion at least into the year 2005. The main reasons are (1 the welfare gap between the EU area and the CEEC, (2 the need for more institutional and economic changes in the CEEC to make them ready for acces-sion, and, most importantly, (3 the necessity for the European Union to prepare herself for accession by a comprehensive financial reform and fundamental institutional changes.

    Knowledge is limited about the bioaccumulation of persistent halogenated compounds (PHCs) in terrestrial wildlife. Several PHCs, including dichlorodiphenyltrichloroethane (DDT) and its metabolites (designated as DDTs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), decabromodiphenylethane (DBDPE) and 1,2-bis(2,4,6-tribromophenoxy) ethane (BTBPE), and stable isotopes (δ15N and δ13C) were analyzed in the muscle of four terrestrial passerines, Parus major, Copsychus saularis, Pycnonotus sinensis and Pycnonotus jocosus, from a nature reserve in South China. P. major had the highest PHC concentrations, with median values of 1060, 401, 92, 25 and 0.3 ng/g lipid weight for DDTs, PCBs, PBDEs, DBDPE and BTBPE, respectively. Fractions of DDT in P. jocosus and PCBs 153, 118 and 180 in C. saularis were higher compared with the other species. The inter-species differences in PHC concentrations and profiles could be attributed to the differences in trophic level, diet, living habits and metabolic capacity among the birds. - Highlights: • PHCs were investigated in terrestrial passerines from a nature reserve in China. • DDTs were the predominant pollutants, followed by PCBs and PBDEs. • Levels of PHCs generally increased with the increasing δ15N value. • Inter-species differences in PHC profiles were observed. - Terrestrial passerines showed inter-species differences in concentrations and contaminant profiles of persistent halogenated compounds

    Causes of interspecific variation in growth rates within and among geographic regions remain poorly understood. Passerine birds represent an intriguing case because differing theories yield the possibility of an antagonistic interaction between nest predation risk and food delivery rates on evolution of growth rates. We test this possibility among 64 Passerine species studied on three continents, including tropical and north and south temperate latitudes. Growth rates increased strongly with nestling predation rates within, but not between, sites. The importance of nest predation was further emphasized by revealing hidden allometric scaling effects. Nestling predation risk also was associated with reduced total feeding rates and per-nestling feeding rates within each site. Consequently, faster growth rates were associated with decreased per-nestling food delivery rates across species, both within and among regions. These relationships suggest that Passerines can evolve growth strategies in response to predation risk whereby food resources are not the primary limit on growth rate differences among species. In contrast, reaction norms of growth rate relative to brood size suggest that food may limit growth rates within species in temperate, but not tropical, regions. Results here provide new insight into evolution of growth strategies relative to predation risk and food within and among species. PMID:21644952

    1. A variety of biochemical measurements were taken periodically in captive northern bobwhite (Colinus virginianus L.), European starlings (Sturnus vulgaris L.), red-winged blackbirds (Agelaius phoeniceus L.) and common grackles (Quiscalus quiscula L.) to determine whether baseline values remain sufficiently stable throughout the year for general clinical use in the absence of concurrent control specimens. 2. Variables included whole blood hematocrit and hemoglobin, plasma lactate dehydrogenase, alpha-hydroxybutyrate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, creatine kinase, butyrylcholinesterase, alkaline phosphatase, glucose, albumin, total protein, creatinine, urea nitrogen, uric acid, cholesterol, and triglycerides, and brain acetylcholinesterase. Butyryl- and acetylcholinesterase were included because of their specific uses in toxicology. 3. Significant seasonal differences were detected for each of the variables except brain acetylcholinesterase in at least one of the species. Significant species differences were detected during at least one season for all of the variables measured. 4. All species were maintained outdoors, but only northern bobwhites came into reproductive condition and showed sex-differences in the clinical variables during their normal breeding season. 5. It was concluded that reference values for the 18 clinical variables measured could be calculated from our data for adult specimens of the species studied, and that results for one species cannot be extrapolated with certainty to any other species. 6. Estimated normal bounds for each of the 18 variables measured by commonly used clinical procedures are presented for reproductively quiescent northern bobwhites, European starlings, red-winged blackbirds, and common grackles.

    After a very brief introduction to history and memory in Europe after 1989, as seen by Aleida Assmann, I will give a short introduction to the EP and to their adoption of resolutions and declarations. Then I will define some concepts central to my study before I proceed to the analysis. Finally I...... will summarise and briefly discuss my findings. The analysis will concentrate on how the memory of the Holocaust has been addressed in the EP from 1989 to 2009. I identify to major changes, one that occurred in the 1990s and one that came about after the 2004 enlargement of the EU and I briefly discuss why...... these changes have come about. Moreover, I show that there seems to be a political memory split between Left and Right and I suggest that the time might not be ripe for a shared European memory....

    Background: The capacity for thermogenesis is considered part of an animal’s adaptive strategy for survival, and basal metabolic rate (BMR) is one of the fundamental physiological standards for assessing the energy cost of ther-moregulation in endotherms. BMR has been shown to be a highly lfexible phenotypic trait both between, and within, species, but the metabolic mechanisms involved in the regulation of BMR, which range from variation in organ mass to biochemical adjustments, remain unclear. In this study, we investigated the relationship between organ mass, biochemical markers of metabolic tissue activity, and thermogenesis, in three species of small passerines: wild Bram-blings (Fringilla montifringilla), Little Buntings (Emberiza pusilla) and Eurasian Tree Sparrows (Passer montanus), caught in Wenzhou, southeastern China. Methods: Oxygen consumption was measured using an open-circuit respirometry system. Mitochondrial state-4 res-piration and cytochrome c oxidase (COX) activity in liver and pectoral muscle were measured with a Clark electrode. Results: Our results show that Eurasian Tree Sparrows had signiifcantly higher BMR, digestive organ mass, mitochon-drial state-4 respiration capacity and COX activity in liver and muscle, than Bramblings and Little Buntings. Further-more, interspeciifc differences in BMR were strongly correlated with those indigestive tract mass, state-4 respiration and COX activity. Conclusions: Our ifndings suggest that the digestive organ mass, state-4 respiration and COX activity play an impor-tant role in determining interspeciifc differences in BMR.

    We examined cell size correlations between tissues, and cell size to body mass relationships in passerine birds, amphibians and mammals. The size correlated highly between all cell types in birds and amphibians; mammalian tissues clustered by size correlation in three tissue groups. Erythrocyte size correlated well with the volume of other cell types in birds and amphibians, but poorly in mammals. In birds, body mass correlated positively with the size of all cell types including erythrocytes, and in mammals only with the sizes of some cell types. Size of mammalian erythrocytes correlated with body mass only within the most taxonomically uniform group of species (rodents and lagomorphs). Cell volume increased with body mass of birds and mammals to less than 0.3 power, indicating that body size evolved mostly by changes in cell number. Our evidence suggests that epigenetic mechanisms determining cell size relationships in tissues are conservative in birds and amphibians, but less stringent in mammals. The patterns of cell size to body mass relationships we obtained challenge some key assumptions of fractal and cellular models used by allometric theory to explain mass-scaling of metabolism. We suggest that the assumptions in both models are not universal, and that such models need reformulation.

  2. Quaternary history of an endemic passerine bird on Corsica Island: Glacial refugium and impact of recent forest regression

    Molecular studies support the hypothesis that Corsica Island was a glacial refugium for a number of forest birds during the Pleistocene. We focused on the Corsican nuthatch (Sitta whiteheadi), an endemic passerine strongly associated with the laricio pine (Pinus nigra laricio). The range of laricio pine has been impacted by the Pleistocene glacial periods and forest has been recently fragmented by cutting and fires. Using both molecular (mitochondrial and nuclear) and morphological characters, we assessed the variation within the nuthatch population. Our results are consistent with the hypothesis that the Corsican nuthatch endured through the late Pleistocene and Holocene climatic variations, and sustained the subsequent cycles of forests reduction/expansion. The results also suggest that the recent anthropization of the landscape resulted in the isolation of a cluster of populations in the northern part of the island. The fragmentation of the habitat of the nuthatch may impede the future of the bird by creating isolated population units between which the gene flow is reduced.

    Theory predicts that because males are more variable in reproductive success than females,a mother should produce more sons to maximize fitness return from the sex allocation if she is of high-quality (the female quality hypothesis) or mates with a high-quality male (the male quality hypothesis).While most previous studies have looked at each hypothesis,we tested both of them simultaneously in the white-rumped snowfinch Montifringilla taczanowskii,a socially monogamous,sexually monomorphic passerine where body size is a potential indicator of individual quality in intrasexual competition and territory defense.Brood sex ratios at the population level did not deviate from random expectation.Among individual broods,the proportion of sons did not depend on body size of either male or female parent,but on interaction of this trait of both parents.Further analyses revealed that brood sex ratios were independent of body size of male or female parents when their mates were smaller,but positively related with body size of male or female parents when their mates were larger.These results suggest that mechanisms underlying the two hypotheses may act jointly on offspring sex allocation.The mechanisms are expected to evolve through size-assortative mating which is often reached by sexual selection.

    Several species of birds and mammals overcome periods of scarcity by caching food, but for the vast majority of species, it is virtually unknown whether they are food limited during these periods. The Gray Jay (Perisoreus canadensis) is a boreal-resident, food-caching passerine that breeds in late winter when fresh food is scarce. Using a two-year experiment and 43 years of monitoring data, we examined the food limitation hypothesis in a population of Gray Jays in Algonquin Park, Ontario, Canada, that has declined by over 50% in the last three decades. Breeding pairs that were experimentally food supplemented during the pre-breeding period laid eggs earlier in the season and had larger brood sizes than non-supplemented controls. From the long-term data, we found strong evidence that pairs that were regularly supplemented by the public (park visitors) tended to lay eggs earlier and have larger clutches and brood sizes compared to pairs that were not supplemented. Nestling body condition (mass controlled for body size) was not influenced by either experimental or public food supplementation. Our results support the hypothesis that Gray Jays are food limited during their late-winter breeding period and suggest that warmer fall temperatures, which have been hypothesized to lead to cache spoilage, may have a significant impact on reproductive success in this declining population. Moreover, our results contribute to understanding how public feeding can influence the fitness of wild animals. PMID:27070019

  6. Seasonally Changing Cryptochrome 1b Expression in the Retinal Ganglion Cells of a Migrating Passerine Bird.

    Directory of Open Access Journals (Sweden)

    Christine Nießner

    Full Text Available Cryptochromes, blue-light absorbing proteins involved in the circadian clock, have been proposed to be the receptor molecules of the avian magnetic compass. In birds, several cryptochromes occur: Cryptochrome 2, Cryptochrome 4 and two splice products of Cryptochrome 1, Cry1a and Cry1b. With an antibody not distinguishing between the two splice products, Cryptochrome 1 had been detected in the retinal ganglion cells of garden warblers during migration. A recent study located Cry1a in the outer segments of UV/V-cones in the retina of domestic chickens and European robins, another migratory species. Here we report the presence of cryptochrome 1b (eCry1b in retinal ganglion cells and displaced ganglion cells of European Robins, Erithacus rubecula. Immuno-histochemistry at the light microscopic and electron microscopic level showed eCry1b in the cell plasma, free in the cytosol as well as bound to membranes. This is supported by immuno-blotting. However, this applies only to robins in the migratory state. After the end of the migratory phase, the amount of eCry1b was markedly reduced and hardly detectable. In robins, the amount of eCry1b in the retinal ganglion cells varies with season: it appears to be strongly expressed only during the migratory period when the birds show nocturnal migratory restlessness. Since the avian magnetic compass does not seem to be restricted to the migratory phase, this seasonal variation makes a role of eCry1b in magnetoreception rather unlikely. Rather, it could be involved in physiological processes controlling migratory restlessness and thus enabling birds to perform their nocturnal flights.

    In recent years, Trichomonas gallinae emerged as the causative agent of an infectious disease of passerine birds in Europe leading to epidemic mortality of especially greenfinches Chloris chloris and chaffinches Fringilla coelebs. After the appearance of finch trichomonosis in the UK and Fennoscandia, the disease spread to Central Europe. Finch trichomonosis first reached Austria and Slovenia in 2012. In the present study the genetic heterogeneity of T. gallinae isolates from incidents in Austria and Slovenia were investigated and compared with British isolates. For this purpose comparative sequence analyses of the four genomic loci ITS1-5.8S-ITS2, 18S rRNA, rpb1 and Fe-hydrogenase were performed. The results corroborate that one clonal T. gallinae strain caused the emerging infectious disease within passerine birds and that the disease is continuing to spread in Europe. The same clonal strain was also found in a columbid bird from Austria. Additionally, the present study demonstrates clearly the importance of multi-locus sequence typing for discrimination of circulating T. gallinae strains. PMID:24476813

  12. Congener-specific egg contribution of polychlorinated biphenyls to nestlings in two passerine species

    International Nuclear Information System (INIS)

    Quantifying polychlorinated biphenyl (PCB) residues in nestlings of avian species is a common method for assessing trophic transfer and risk at PCB-contaminated sites. The proportion of nestling PCB mass due to maternal transfer is often accounted for by subtracting total PCB mass in eggs from nestlings. However, variation in physicochemical properties and metabolism among congeners may lead to differences between egg contribution based on total PCBs and dioxin-like congeners. We examined congener-specific variation in contribution of PCBs from eggs to nestlings in tree swallows and European starlings. Egg contribution of total PCB mass was 14.3 and 16.2%, respectively, whereas contribution based on dioxin-like congeners was 14.8 and 13.6%, respectively. These data suggest that using total PCB mass in eggs to adjust estimates of PCB accumulation in nestlings may not reflect patterns for dioxin-like congeners, potentially over or under-estimating the risk of toxicity of PCBs. - Congener-specific contribution of PCBs from egg to nestlings was examined.

    Although a number of studies have addressed the bioaccumulation of Dechlorane Plus (DP) flame retardant in wildlife, few data are available on terrestrial organisms. This study examined the presence of DP isomers in the muscle tissue of seven terrestrial resident passerine species, i.e., the great tit (Parus major), the oriental magpie-robin (Copsychus saularis), the red-whiskered bulbul (Pycnonotus jocosus), the light-vented bulbul (Pycnonotus sinensis), the streak-breasted scimitar babbler (Pomatorhinus ruficollis), the long-tailed shrike (Lanius schach), and the orange-headed thrush (Zoothera citrina), from a national nature reserve located in South China. The ∑DP (sum of syn-DP and anti-DP) concentrations ranged from 1.2 to 104 ng/g lipid weight, with significantly higher levels in insectivorous birds than in omnivorous birds. The overall exposure to DP isomers of the current passerines may be attributed to the intensive release of this pollutant from electronic waste recycling sites and industrial zones in the vicinity of the nature reserve. Species-specific DP isomeric profiles were also found, with significantly greater f{sub anti} values (the isomer fractions of anti-DP) in the red-whiskered bulbul and the oriental magpie-robin. Additionally, the f{sub anti} values were significantly negatively correlated to ∑DP concentrations for the individual bird samples, suggesting the influence of DP concentrations on the isomeric profiles. - Highlights: • We investigated the occurrence of DP in seven species of terrestrial passerines. • Insectivorous birds accumulated higher ∑DP concentrations than omnivorous birds. • Inter-species differences in the f{sub anti} values were observed. • The f{sub anti} values were significantly correlated to DP concentrations.

  14. EUROPEAN AUSTERITY WITHOUT GROWTH? EUROPEAN GROWTH WITHOUT EUROPEAN DEMOCRACY?

    Directory of Open Access Journals (Sweden)

    2011-07-01

    Full Text Available The European project is facing a crisis. Citizens no longer understand what the EU is about. Young people and the new ruling class have forgotten the clear message of the European project launched just after the Second World War "No wars ever again among Europeans." The founding fathers of the European Union are mentioned in history textbooks, but today Europe is felt as an irritating bureaucracy. In Europe, peace and economic stability are considered as a natural state, a gift from above. Why keep a useless EU alive? The state of the European Union is swiftly degenerating. In almost all the member states, the anti-European forces are gaining ground. Populism is not a new ideology and is not necessarily European: let's recall Peronism. In today's Europe populism is the new manifestation of nationalism. In Italy the Lega Nord is in Berlusconi's eurosceptic government. In France, the National Front is endangering UMP's hegemony. In Belgium the rows between the Flemish and the Walloons threatens the state's unity. In the Netherlands, Hungary, the Czech Republic, Austria and Finland, populist forces are either in the government or strongly influencing the government. National-populism is different from the nationalism of the past. De Gaulle's nationalism was an ideology founded on the "grandeur" of France's history and on a certain idea of Europe, which was "l'Europe de patrie", a kind of European unity accepting French leadership in world politics. Today national-populism is a form of micro-nationalism: it opposes the European project but without having a serious alternative. This is why populism is dangerous. Its real goal is not only the breaking down of the European Union but also the disintegration of the old nation states into micro-ethnic states, as what happened in former Yugoslavia.

    Female birds may adjust their offspring phenotype to the specific requirements of the environment by differential allocation of physiologically active substances into yolks, such as androgens. Yolk androgens have been shown to accelerate embryonic development, growth rate and competitive ability of nestlings, but they can also entail immunological costs. The balance between costs and benefits of androgen allocation is expected to depend on nestling environment. We tested this hypothesis in a multibrooded passerine, the spotless starling, Sturnus unicolor. We experimentally manipulated yolk androgen levels using a between-brood design and evaluated its effects on nestling development, survival and immune function. Both in first and replacement broods, the embryonic development period was shorter for androgen-treated chicks than controls, but there were no differences in second broods. In replacement broods, androgen-treated chicks were heavier and larger than those hatched from control eggs, but this effect was not observed in the other breeding attempts. Androgen exposure reduced survival with respect to controls only in second broods. Regarding immune function, we detected nonsignificant trends for androgen treatment to activate two important components of innate and adaptive immunity (IL-6 and Ig-A levels, respectively). Similarly, androgen-treated chicks showed greater lymphocyte proliferation than controls in the first brood and an opposite trend in the second brood. Our results indicate that yolk androgen effects on nestling development and immunity depend on the environmental conditions of each breeding attempt. Variation in maternal androgen allocation to eggs could be explained as the result of context-dependent optimal strategies to maximize offspring fitness.

    Seed-eating birds have a diet of high nutritional value; however, they must cope with plant secondary metabolites (PSM). We postulated that the detoxification capacity of birds is associated with a metabolic cost, given that the organs responsible for detoxification significantly contribute to energetic metabolism. We used an experimental approach to assess the effects of phenol-enriched diets on two passerines with different feeding habits: the omnivorous rufous-collared sparrow (Zonotrichia capensis) and the granivorous common diuca-finch (Diuca diuca). The birds were fed with one of three diets: control diet, supplemented with tannic acid, or supplemented with Opuntia ficus-indica phenolic extract (a common food of the sparrow but not the finch). After 5 weeks of exposure to the diets, we measured basal metabolic rates (BMR), energy intake, glucuronic acid output and digestive and kidney structure. In both species, detoxification capacity expressed as glucuronic acid output was higher in individuals consuming phenol-enriched diets compared to the control diet. However, whereas sparrows increase energy intake and intestinal mass when feeding on phenol-enriched diets, finches had lower intestinal mass and energy intake remains stable. Furthermore, sparrows had higher BMR on phenol-enriched diets compared to the control group, whereas in the finches BMR remains unchanged. Interspecific differences in response to phenols intake may be determined by the dietary habits of these species. While both species can feed on moderate phenolic diets for 5 weeks, energy costs may differ due to different responses in food intake and organ structure to counteract the effects of PSM intake.

    Two species of Acuaria were collected from passerine birds from the Area de Conservacion Guanacaste, Costa Rica. Acuaria mayori Lent, Freitas and Proenca, 1945, was collected from Myiarchus nuttingi. Specimens from Costa Rica differ from the original description by having a spicule ratio of 1:1.5-1.7 versus 1:1.43-1.47, as well as shorter spicules and female tails. Acuaria wangi n. sp. in Hylophylax naevioides and Gymnopithys leucaspis resembles A. alii, A. crami, A. cyanocitta, A. minuta, A. pattoni, and A. cissae by having cordons extending posteriorly to the anterior portion of the glandular esophagus. The new species differs from A. alii by having 4 pairs of preanal and 6 pairs of postanal papillae rather than 2 pairs of preanal and 7 pairs of postanal papillae, a shorter left spicule, a spicule ratio of 1:1.6-1.8 versus 1:1.1 and in having spicules with blunt rather than pointed distal ends. Acuaria crami and A. minuta differ from A. wangi by having 7 pairs of postanal papillae and spicule ratios of 1:1.6-1.8 versus 1:1.3 in A. crami and 1:1.1 in A. minuta; in addition, A. minuta has spatulate-shaped spicules and a tricupsid-shaped distal end of the right spicule. The new species can be distinguished from A. pattoni by having a longer left spicule and a spicule ratio of 1:1.6-1.8 versus 1:1 and from A. cissae by having a shorter left spicule and a spicule ratio of 1:1.6-1.8 versus 1:2.5-2.7. Acuaria wangi is similar to A. cyanocitta, which has similarly shaped spicules, including a very pointed distal end of the left spicule, but differs in body length, in having shorter spicules, in the arrangement of postanal papillae, and in having smaller eggs.

    The relationship between sperm energetics and sperm function is poorly known, but is central to our understanding of the evolution of sperm traits. The aim of this study was to examine how sperm morphology and ATP content affect sperm swimming velocity in the zebra finch Taeniopygia guttata We exploited the high inter-male variation in this species and created extra experimental power by increasing the number of individuals with very long or short sperm through artificial selection. We found a pronounced quadratic relationship between total sperm length and swimming velocity, with velocity increasing with length up to a point, but declining in the very longest sperm. We also found an unexpected negative association between midpiece length and ATP content: sperm with a short midpiece generally contained the highest concentration of ATP. Low intracellular ATP is therefore unlikely to explain reduced swimming velocity among the very longest sperm (which tend to have a shorter midpiece). PMID:27559067

    Although a number of studies have addressed the bioaccumulation of Dechlorane Plus (DP) flame retardant in wildlife, few data are available on terrestrial organisms. This study examined the presence of DP isomers in the muscle tissue of seven terrestrial resident passerine species, i.e., the great tit (Parus major), the oriental magpie-robin (Copsychus saularis), the red-whiskered bulbul (Pycnonotus jocosus), the light-vented bulbul (Pycnonotus sinensis), the streak-breasted scimitar babbler (Pomatorhinus ruficollis), the long-tailed shrike (Lanius schach), and the orange-headed thrush (Zoothera citrina), from a national nature reserve located in South China. The ∑DP (sum of syn-DP and anti-DP) concentrations ranged from 1.2 to 104 ng/g lipid weight, with significantly higher levels in insectivorous birds than in omnivorous birds. The overall exposure to DP isomers of the current passerines may be attributed to the intensive release of this pollutant from electronic waste recycling sites and industrial zones in the vicinity of the nature reserve. Species-specific DP isomeric profiles were also found, with significantly greater fanti values (the isomer fractions of anti-DP) in the red-whiskered bulbul and the oriental magpie-robin. Additionally, the fanti values were significantly negatively correlated to ∑DP concentrations for the individual bird samples, suggesting the influence of DP concentrations on the isomeric profiles.

  8. West European magnetic confinement fusion research

    International Nuclear Information System (INIS)

    This report presents a technical assessment and review of the West European program in magnetic confinement fusion by a panel of US scientists and engineers active in fusion research. Findings are based on the scientific and technical literature, on laboratory reports and preprints, and on the personal experiences and collaborations of the panel members. Concerned primarily with developments during the past 10 years, from 1979 to 1989, the report assesses West European fusion research in seven technical areas: tokamak experiments; magnetic confinement technology and engineering; fusion nuclear technology; alternate concepts; theory; fusion computations; and program organization. The main conclusion emerging from the analysis is that West European fusion research has attained a position of leadership in the international fusion program. This distinction reflects in large measure the remarkable achievements of the Joint European Torus (JET). However, West European fusion prominence extends beyond tokamak experimental physics: the program has demonstrated a breadth of skill in fusion science and technology that is not excelled in the international effort. It is expected that the West European primacy in central areas of confinement physics will be maintained or even increased during the early 1990s. The program's maturity and commitment kindle expectations of dramatic West European advances toward the fusion energy goal. For example, achievement of fusion breakeven is expected first in JET, before 1995

    Full Text Available Abstract Background Wild birds contribute to maintenance and dissemination of vectors and microbes, including those that impact human, domestic animal, and wildlife health. Here we elucidate roles of wild passerine birds, eastern cottontail rabbits (Sylvilagus floridanus, and Ixodes dentatus ticks in enzootic cycles of two spirochetes, Borrelia miyamotoi and B. andersonii in a region of Michigan where the zoonotic pathogen B. burgdorferi co-circulates. Methods Over a four-year period, wild birds (n = 19,631 and rabbits (n = 20 were inspected for tick presence and ear tissue was obtained from rabbits. Samples were tested for Borrelia spirochetes using nested PCR of the 16S-23S rRNA intergenic spacer region (IGS and bidirectional DNA sequencing. Natural xenodiagnosis was used to implicate wildlife reservoirs. Results Ixodes dentatus, a tick that specializes on birds and rabbits and rarely bites humans, was the most common tick found, comprising 86.5% of the 12,432 ticks collected in the study. The relapsing fever group spirochete B. miyamotoi was documented for the first time in ticks removed from wild birds (0.7% minimum infection prevalence; MIP, in I. dentatus, and included two IGS strains. The majority of B. miyamotoi-positive ticks were removed from Northern Cardinals (Cardinalis cardinalis. Borrelia andersonii infected ticks removed from birds (1.6% MIP, ticks removed from rabbits (5.3% MIP, and rabbit ear biopsies (5% comprised twelve novel IGS strains. Six species of wild birds were implicated as reservoirs for B. andersonii. Frequency of I. dentatus larval and nymphal co-feeding on birds was ten times greater than expected by chance. The relatively well-studied ecology of I. scapularis and the Lyme disease pathogen provides a context for understanding how the phenology of bird ticks may impact B. miyamotoi and B. andersonii prevalence and host associations. Conclusions Given the current invasion of I. scapularis, a human biting species

  11. Deimatic display in the European swallowtail butterfly as a secondary defence against attacks from great tits.

    Directory of Open Access Journals (Sweden)

    Martin Olofsson

    Full Text Available BACKGROUND: Many animals reduce the risk of being attacked by a predator through crypsis, masquerade or, alternatively, by advertising unprofitability by means of aposematic signalling. Behavioural attributes in prey employed after discovery, however, signify the importance of also having an effective secondary defence if a predator uncovers, or is immune to, the prey's primary defence. In butterflies, as in most animals, secondary defence generally consists of escape flights. However, some butterfly species have evolved other means of secondary defence such as deimatic displays/startle displays. The European swallowtail, Papilio machaon, employs what appears to be a startle display by exposing its brightly coloured dorsal wing surface upon disturbance and, if the disturbance continues, by intermittently protracting and relaxing its wing muscles generating a jerky motion of the wings. This display appears directed towards predators but whether it is effective in intimidating predators so that they refrain from attacks has never been tested experimentally. METHODOLOGY/PRINCIPAL FINDINGS: In this study we staged encounters between a passerine predator, the great tit, Parus major, and live and dead swallowtail butterflies in a two-choice experiment. Results showed that the dead butterfly was virtually always attacked before the live butterfly, and that it took four times longer before a bird attacked the live butterfly. When the live butterfly was approached by a bird this generally elicited the butterfly's startle display, which usually caused the approaching bird to flee. We also performed a palatability test of the butterflies and results show that the great tits seemed to find them palatable. CONCLUSIONS/SIGNIFICANCE: We conclude that the swallowtail's startle display of conspicuous coloration and jerky movements is an efficient secondary defence against small passerines. We also discuss under what conditions predator-prey systems are likely to

Even so, the policies above still worth affirmation. Compared with“rights protection”idea,“Social Inclusion”is a historical Leap of minority policy.

As a result, over 20 European countries will be covered with the ELF topo Base Map in 2016. Most countries will contribute also with other harmonized thematic data for viewing or down-loading. To overcome the heterogeneity of data resources and diversity of languages in tens of European countries, ELF builds on the existing INSPIRE rules and its own coordination and interoperability measures. ELF realisation empowers the implementation of INSPIRE in Europe and it complements related activities of European NMCAs, e.g. Czech Office for Surveying, Mapping and Cadastre (CUZK), which provides a large portfolio of spatial data/services and contributes significantly to the NSDI of Czech Republic. CUZK is also responsible for the Base Register of Territorial Identification, Addresses and Real Estates (RUIAN) - an important pillar of Czech e-Government. CUZK became an early-bird in implementing INSPIRE and it provides to the ELF a number of compliant datasets and web services. CUZK and the Polish NMCA (GUGiK) collaborate in the Central-European ELF Pilot (cluster) and test various cross-border prototypes. The presentation combines the national and crossborder view and experiences of CUZK and the European perspective of EuroGeographics.

    The current study aimed at quantifying arsenic and lead in feathers from three passerine species that are residents from areas exposed to mining activities (Toxostoma curvirostre, Campylorhynchus brunneicapillus, and Melozone fusca). Lead and As contents in bird feathers and in superficial soil samples were measured with AAS. Levels of these metals were compared between sites exposed and unexposed to mining. Possible correlations of As and Pb between superficial soil and bird feathers were also investigated. Soil metal concentrations were significantly higher near mining sites, and metal concentrations in bird feathers showed a behavior similar to those recorded for soil samples. Individual birds from polluted sites had higher mean feather metal concentrations in comparison with non-polluted sites; no differences in metal concentrations were recorded among bird species. This work constitutes a basis for monitoring contaminants, and for future toxicological studies attempting to understand the impact that some mining activities may have on bird populations.

    Office blood pressure measurement has been the basis for hypertension evaluation for almost a century. However, the evaluation of blood pressure out of the office using ambulatory or self-home monitoring is now strongly recommended for the accurate diagnosis in many, if not all, cases with suspected hypertension. Moreover, there is evidence that the variability of blood pressure might offer prognostic information that is independent of the average blood pressure level. Recently, advancement in technology has provided noninvasive evaluation of central (aortic) blood pressure, which might have attributes that are additive to the conventional brachial blood pressure measurement. This position statement, developed by international experts, deals with key research and practical issues in regard to peripheral blood pressure measurement (office, home, and ambulatory), blood pressure variability, and central blood pressure measurement. The objective is to present current achievements, identify gaps in knowledge and issues concerning clinical application, and present relevant research questions and directions to investigators and manufacturers for future research and development (primary goal).

  2. Does migratory distance affect fuelling in a medium-distance passerine migrant?: results from direct and step-wise simulated magnetic displacements

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available In birds, fat accumulation before and during migration has been shown to be endogenously controlled and tuned by, among other factors, the Earth's magnetic field. However, our knowledge about the influence of the geomagnetic field on the fuelling in migrating birds is still limited to just a few nocturnally migrating passerine species. In order to study if variations of the magnetic field can also influence the fuelling of both day- and night-migrating passerines, we caught first-year dunnocks (Prunella modularis and subjected them to three magnetic field conditions simulated by a system of magnetic coils: (1 local geomagnetic field of southern Sweden, (2 magnetic field corresponding to the centre of the expected wintering area, and (3 magnetic field met at the northern limit of the species' breeding distribution. We did not find a difference in mass increase between the birds kept in a local magnetic field and a field resembling their wintering area, irrespectively of the mode of magnetic displacement, i.e. direct or step-wise. However, the dunnocks magnetically displaced north showed a lower rate of fuelling in comparison to the control group, probably due to elevated activity. Compared with previous studies, our results suggest that the fuelling response to magnetic displacements during the migration period is specific to the eco-physiological situation. Future studies need to address if there is an effect of magnetic field manipulation on the level of migratory activity in dunnocks and how widespread the influence of local geomagnetic field parameters is on fuelling decisions in different bird species, which have different migratory strategies, distances and migration history.

    Using a genome-wide single nucleotide polymorphism (SNP) panel, we observed population structure in a diverse group of Europeans and European Americans. Under a variety of conditions and tests, there is a consistent and reproducible distinction between “northern” and “southern” European population groups: most individual participants with southern European ancestry (Italian, Spanish, Portuguese, and Greek) have >85% membership in the “southern” population; and most northern, western, eastern, and central Europeans have >90% in the “northern” population group. Ashkenazi Jewish as well as Sephardic Jewish origin also showed >85% membership in the “southern” population, consistent with a later Mediterranean origin of these ethnic groups. Based on this work, we have developed a core set of informative SNP markers that can control for this partition in European population structure in a variety of clinical and genetic studies.

    2011-08-01

    Full Text Available The issues referring to official statistics quality and reliability became the main topics of debates as far as statistical governance in Europe is concerned. The Council welcomed the Commission Communication to the European Parliament and to the Council « Towards robust quality management for European Statistics » (COM 211, appreciating that the approach and the objective of the strategy would confer the European Statistical System (ESS the quality management framework for the coordination of consolidated economic policies. The Council pointed out that the European Statistical System management was improved during recent years, that progress was noticed in relation with high quality statistics production and dissemination within the European Union, but has also noticed that, in the context of recent financial crisis, certain weaknesses were identified, particularly related to quality management general framework.„Greece Case” proved that progresses were not enough for guaranteeing the complete independence of national statistical institutes and entailed the need for further consolidating ESS governance. Several undertakings are now in the preparatory stage, in accordance with the Commission Communication; these actions are welcomed, but the question arise: are these sufficient for definitively solving the problem?The paper aims to go ahead in the attempt of identifying a different way, innovative (courageous! on the long run, towards an advanced institutional structure of ESS, by setting up the European System of Statistical Institutes, similar to the European System of Central Banks, that would require a change in the Treaty.

  16. European Union and oil

    International Nuclear Information System (INIS)

    In a context of oil price increase, problems about a Russian oil company (Loukos), and uncertainties in the Middle-East, the possibility of a new oil shock is a threat for Europe, and raises the issue of a true European energy policy which would encompass, not only grid development, environmental issues or market regulation issues, but also strategic issues related to energy supply security. This article proposes an overview of the European policy: first steps for a future European energy and oil policy in the green paper of the European Commission published in November 2000, issues of pollution and safety for hydrocarbon maritime transport. The article then examines the possibility of a third oil shock due to a crisis in the Middle East, and discusses whether European must have strategic stocks to face an outage of oil supplies

    Objectives It is still debated if pre-existing minority drug-resistant HIV-1 variants (MVs) affect the virological outcomes of first-line NNRTI-containing ART. Methods This Europe-wide case–control study included ART-naive subjects infected with drug-susceptible HIV-1 as revealed by population sequencing, who achieved virological suppression on first-line ART including one NNRTI. Cases experienced virological failure and controls were subjects from the same cohort whose viraemia remained suppressed at a matched time since initiation of ART. Blinded, centralized 454 pyrosequencing with parallel bioinformatic analysis in two laboratories was used to identify MVs in the 1%–25% frequency range. ORs of virological failure according to MV detection were estimated by logistic regression. Results Two hundred and sixty samples (76 cases and 184 controls), mostly subtype B (73.5%), were used for the analysis. Identical MVs were detected in the two laboratories. 31.6% of cases and 16.8% of controls harboured pre-existing MVs. Detection of at least one MV versus no MVs was associated with an increased risk of virological failure (OR = 2.75, 95% CI = 1.35–5.60, P = 0.005); similar associations were observed for at least one MV versus no NRTI MVs (OR = 2.27, 95% CI = 0.76–6.77, P = 0.140) and at least one MV versus no NNRTI MVs (OR = 2.41, 95% CI = 1.12–5.18, P = 0.024). A dose–effect relationship between virological failure and mutational load was found. Conclusions Pre-existing MVs more than double the risk of virological failure to first-line NNRTI-based ART.

  7. The European natural gas market

    International Nuclear Information System (INIS)

    An increasing amount of natural gas is flowing into continental Europe, one of the largest gas markets in the world. There are three main sources of gas: Africa, Russia and Norway. Norway is an important supplier of gas, but may be vulnerable to competition. The demand for gas is increasing on a global basis and the largest increase is expected in Asia, followed by America and Europe. It is expected that Norwegian gas deliveries will be a principle source of natural gas for North Europe in the next years and that they will take an increasing part of the British market as the gas deliveries from the British shelf is going down. The European gas market is likely to become liberalized according to the EU's competition- and gas directives. This will not necessarily be a problem, and Norway may be able to increase the export of gas to Great Britain considerably from the year 2010, perhaps up to 40 billion standard m3 per year. Russia is expected to take an increased share of the European gas market, especially in East- and Central Europe, Germany and North Italy. But large investments in existing fields, new developments and new strategic pipelines are necessary

    2012-01-01

    Discourse analysis as a methodology is perhaps not readily associated with substantive causality claims. At the same time the study of discourses is very much the study of conceptions of causal relations among a set, or sets, of agents. Within Europeanization research we have seen endeavours...... to develop discursive institutional analytical frameworks and something that comes close to the formulation of hypothesis on the effects of European Union (EU) policies and institutions on domestic change. Even if these efforts so far do not necessarily amount to substantive theories or claims of causality......, it suggests that discourse analysis and the study of causality are by no means opposites. The study of Europeanization discourses may even be seen as an essential step in the move towards claims of causality in Europeanization research. This chapter deals with the question of how we may move from the study...

  13. Ethics and European security

    Energy Technology Data Exchange (ETDEWEB)

    Paskins, B.

    1986-01-01

    The alliance between the United States and her NATO partners has been strained severely in the last few years. American perceptions of European disloyalty and European impressions of American assertiveness and lack of judgment have played a large part in generating tensions between the allies and emphasising the new peace movements. This book is an attempt to develop a broader understanding of the problem of European security based on Christian ethics. There are disagreements and differences of emphasis among the contributors but they have in common the view that an exclusive preoccupation with the military dimension is damagingly one-sided. Instead the contributors argue that moral and theological concerns are a vital part of the politics and mechanics of European security and must be incorporated in any effort to devise new policies for security in Europe and the West.
