  2. 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

  3. Central European gas market perspectives

    Full Text Available The paper presents a modelling approach for performance comparison of Central European companies on three levels: country, industry, and company. The approach is based on Data Envelopment Analysis and Analytic Hierarchy Process. The proposed model consists of two basic sections. The first section estimates the importance of selected industries in the countries, whereas the second section evaluates the performance of companies within industries. The results of both sections are synthesized and finally the country performance is estimated. The evaluation is based on the data set resulting from a survey of companies from selected industries.

  7. Workers doses in central European PWR NPPs

    International Nuclear Information System (INIS)

    As is stated, the ISOE database which was established in 1992 forms an excellent basis for studies and comparisons of occupational exposure data between nuclear power plants. In the year 2001, 69% of all participating reactors were pressurised water reactors. The ISOE database presents workers' exposure from 213 participating pressurised reactors (PWR) from 27 countries in that year. Among these 32 PWRs belong to six Central European Countries. The analysis of the exposure of workers based on radiation protection performance indicators (collective dose, average dose etc.) in these PWRs could be related to some nuclear safety performance indicators for recent years using ISOE database. The comparison is made to ISOE world - wide data. In the six Central European Countries altogether 32 PWR operated in the year 2001.The international databases of performance indicators related to radiation protection as for example the ISOE or the UNSCEAR database can be use as an efficient tool in the management of radiation protection of workers in a nuclear facilities and regulatory bodies. The databases enable the study of performance trends and the improvement of radiation protection. (authors)

    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 ...

    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.

    Diet analysis is an important aspect when investigating the ecology of fish-eating animals and essential for assessing their functional role in food webs across aquatic and terrestrial ecosystems. The identification of fish remains in dietary samples, however, can be time-consuming and unsatisfying using conventional morphological analysis of prey remains. Here, we present a two-step multiplex PCR system, comprised of six assays, allowing for rapid, sensitive and specific detection of fish DNA in dietary samples. This approach encompasses 78 fish and lamprey species native to Central European freshwaters and enables the identification of 31 species, six genera, two families, two orders and two fish family clusters. All targeted taxa were successfully amplified from 25 template molecules, and each assay was specific when tested against a wide range of invertebrates and vertebrates inhabiting aquatic environments. The applicability of the multiplex PCR system was evaluated in a feeding trial, wherein it outperformed morphological prey analysis regarding species-specific prey identification in faeces of Eurasian otters. Additionally, a wide spectrum of fish species was detected in field-collected faecal samples and regurgitated pellets of Common Kingfishers and Great Cormorants, demonstrating the broad applicability of the approach. In conclusion, this multiplex PCR system provides an efficient, easy to use and cost-effective tool for assessing the trophic ecology of piscivores in Central Europe. Furthermore, the multiplex PCRs and the primers described therein will be applicable wherever DNA of the targeted fish species needs to be detected at high sensitivity and specificity. PMID:26053612

  13. 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.

We conducted a four-year field study as well as a bibliographical survey where we determined: presence of botfly parasitism, type of nest, presence of green material and small sticks in the nest, average height of the nest, date of last nesting attempt during the breeding season and egg volume (as a surrogate of species body mass. 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.

    2009-07-01

    The development of quantum optics was part and parcel of the formation of modern physics following the fundamental work of Max Planck and Albert Einstein, which gave rise to quantum mechanics. The possibility of working with pure quantum objects, like single atoms and single photons, has turned quantum optics into the main tool for testing the fundamentals of quantum physics. Thus, despite a long history, quantum optics nowadays remains an extremely important branch of physics. It represents a natural base for the development of advanced technologies, like quantum information processing and quantum computing. Previous Central European Workshops on Quantum Optics (CEWQO) took place in Palermo (2007), Vienna (2006), Ankara (2005), Trieste (2004), Rostock (2003), Szeged (2002), Prague (2001), Balatonfüred (2000), Olomouc (1999), Prague (1997), Budmerice (1995, 1996), Budapest (1994) and Bratislava (1993). Those meetings offered excellent opportunities for the exchange of knowledge and ideas between leading scientists and young researchers in quantum optics, foundations of quantum mechanics, cavity quantum electrodynamics, photonics, atom optics, condensed matter optics, and quantum informatics, etc. The collaborative spirit and tradition of CEWQO were a great inspiration and help to the Institute of Physics, Belgrade, and the Serbian Academy of Sciences and Arts, as the organizers of CEWQO 2008. The 16th CEWQO will take place in 2009 in Turku, Finland, and the 17th CEWQO will be organized in 2010 in St Andrews, United Kingdom. The 15th CEWQO was organized under the auspices and support of the Ministry of Science of the Republic of Serbia, the Serbian Physical Society, the European Physical Society with sponsorship from the University of Belgrade, the Central European Initiative, the FP6 Program of the European Commission under INCO project QUPOM No 026322, the FP7 Program of the European Commission under project NANOCHARM, Europhysics Letters (EPL), The European

    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.

  9. A quality assurance network in Central European Countries

    International Nuclear Information System (INIS)

    A survey of the infrastructure in r[iotherapy centres in three Central European countries has been performed as a first step in the development of a quality assurance network. Data concerning r[iotherapy equipment, staff and number of patients treated in most of the r[iotherapy centres from Czech Republic, Poland and Hungary were collected at the beginning of 1994. Equipment data have shown that 35% of 182 treatment units are conventional X-ray units, 35% 60Co units, 19% linear accelerators, 7% 137Cs units and 4% betatrons. About 47% of high energy units are older than 12 years and about 20% older than 21 years. An important number of centres still have no simulator which would constitute an important handicap to carry out [equate r[iotherapy. The number of treatment planning systems has also been registered; 44% being PC-based systems with locally developed software. Large variations are observed in the number of patients treated per year, per high energy unit, but 12/47 centres treat more than 700 patients per year and unit. On the average, staffing seems [equate in numbers though there are wide variations. The main limitation of r[iotherapy infrastructure in the Central European countries is the low number of linear accelerators and simulators and the [vanced age of therapy units. (orig.)

    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.)

  11. 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

  12. 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.

    In this chapter of the book author deals with the economic, social, ecological and cultural problems in connection of the Gabcikovo-Nagymaros Project (GNP) with the integration process of the 12 European Communities countries. Slovakia - sometimes also called the corridor between the East and the West - appears to have great potential as a link in the general east-west integration. Such a role could be further reinforced by the close and purposeful cooperation between Slovakia, Hungary, Slovenia, Austria and Bavaria, and it could have a positive signal effect for the whole of Central Europe, as well as for Europe in general. However, this is possible only provided that the former COMECON countries will reduce their tendency to compete for western attention and they will begin, to a larger extent, to lay down the foundations for the indisputable benefits accruing to their population from cooperation and integration. In this respect, the GNP appears to be a crucial issue an the social and political decision on the completion of the Project would become a signal that Central Europe has entered the path towards becoming one of the most important regions of Europe

  16. Risk assessment of chemicals: A central European perspective

    International Nuclear Information System (INIS)

    During the last four decades in the Czech and Slovak federal Republic (CSFR) and Hungary, similar to the previous Soviet Union and all the Central and East European countries the prevention of the adverse health effects of chemicals in occupational and environmental settings, drinking water and food of population was intended to be achieved by determination and compulsory observance of hygienic limit values. From recent political developments it can be expected that due to the decay of the former Warsaw Pact and the related Council for Mutual Economic Assistance (CMEA) the next development of risk assessment will reflect that new situation. The OECD principles of toxicity testing and risk assessment of exposure to chemicals will be sooner or later accepted in principle in the framework of a general economic integration of Central and Eastern European countries with EEC. During the 80s there was a growing feeling of the necessity to harmonize the activities of OECD and CMEA countries in the field of toxicological methodology and approaches to risk assessment of chemicals because of the growing production and mutual trade including transport of industrial and agricultural chemicals. As a contributory factor supporting this effort there was growing cross boundary air and river pollution in Europe. The former Council for Mutual Economic Assistance was an intergovernmental organization of 10 countries with a number of other countries and agencies cooperating with it in its work. CMEA as, and OECD still is concerned primarily with economic development but both had stated commitments to protecting human health and the environment. To help to mutual understanding and to promote harmonization of above mentioned obligations and commitments of the both organizations United Nation Environment Programme's International Registry of Potentially Toxic Chemicals and The International Programme on Chemical Safety (UNEP/IRPTC/IPCS) convened an International Consultation on

    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.

  18. Thermal footprints in groundwater of central European cities

    Atmospheric thermal pollution in densely populated areas is recognized as a severe problem with consequences for human health, and considerable efforts are being taken to mitigate heat stress in cities. However, anthropogenic activities also influence the thermal environment beneath the ground level, with commonly growing temperatures that affect groundwater ecology and geothermal use efficiency. In our work, we identify the controlling mechanisms for the long-term evolution of such urban heat islands. The shallow groundwater temperatures in several central European cities such as Cologne, Karlsruhe, Munich, Berlin and Zurich were mapped at high spatial and temporal resolution. Thermal anomalies were found to be highly heterogeneous with local hot spots showing temperatures of more than 20°C. Accordingly, these urban regions show a considerable groundwater warming in comparison to undisturbed temperatures of 8-11°C. Examination of potential heat sources by analytical modelling reveals that increased ground surface temperatures and basements of buildings act as dominant drivers for the anthropogenic heat input into the groundwater. The factors are revealed to be case-specific and they may have pronounced local or regional effects. Typical local factors are for example buried district heating networks. In selected cities we find that the average urban heat flux is around one order of magnitude higher than the elevated ground heat flux due to recent climate change. Additionally, such as observed in Zurich, naturally controlled temperature variations can be substantial and they are shown to wash out anthropogenic thermal footprints.

  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

    Full Text Available Enlargement has become a fundamental priority of the European Union after the 90’s. Up to now seven rounds have been held for enlarging the Community which initially was made up of six Member States (Belgium, Germany, France, Italy, Luxembourg, Netherlands. Among all EU enlargements, the eastward enlargement from 2004 was the biggest challenge, both due to the number of new Member States which joined - the number of EU inhabitants increasing to approximately from 380 to 485 million, but also due to the difference of Gross Domestic Product between the old and new EU members. This paper aims to provide insights in European integration and absorption of European funds into the newest that joined the European Union. The paper proposes an analysis of integration and specialization in Eastern Europe by means of data and statistics provided by European and national statistics institutions.

    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

  11. European future natural gas demand and supply diversification: key issues for Central and Eastern Europe

    International Nuclear Information System (INIS)

    After the breakdown of the former Soviet Union and the COMECON the demarcation line between western Europe and central/eastern Europe has disappeared. The central and eastern European economies as a whole and their gas industries as well as the western European gas companies are preparing for the future enlarged market in creating the prerequisites to participate successfully in such a market and to seize the opportunities this market is offering. The framework for this future European Gas Market has to be created now. The European gas industries and gas markets are in transition and are in a process of reshaping, with the following challenges: (1) In Central and Eastern European countries: To complete the privatization and restructuring process from centrally-planned economies to market-oriented structures with deregulated prices, market-oriented tariff systems and new legal and regulatory frameworks. These are the essential prerequisites for an integration of the central and eastern European countries into a single European gas market and the basis for an effective and successful trans border gas co-operation between east and west. (2) In western European countries: To pursue nearly similar processes of restructuring which are underway: privatization by reducing state participation and influence in gas and energy companies, with the accent on liberalization and deregulation of market structures with fewer market entry barriers, and more competition by reducing the influence of state or private monopolies. Gas companies are undertaking cost-efficiency measures to be prepared to meet the requirements of more competitive market structures and also of a more advanced internationalized gas business. The fundamental rules on which western European gas industries based their operations up to now have to be reconsidered. The old western European structures which have developed under the shelter of governmental protection are under pressure from several sources. EU energy

  4. Occupational radiation exposure in Central and Eastern European countries - ESOREX EAST -. Proceedings

    International Nuclear Information System (INIS)

    On behalf of the European Commission, the BfS is currently executing a project entitled 'European Study of Occupational Radiation Exposure - ESOREX'. The project consists of several surveys executed in the Member States of the European Union, furthermore in Iceland, Norway and Switzerland. In each of these countries the - 1. administrative systems used to register individual occupational radiation exposure, - 2. numbers and dose distributions of occupationally radiation exposed persons in 1995 are surveyed. The aim is to describe and compare the administrative structures of the various national registration systems and the distributions of the workers and their doses. It shall identify the differences between the states and analyse the possibilities for a European harmonization. Because of the intention of numerous Central and Eastern European countries to join the European Community, the harmonization theme is also of considerable importance for these countries. The workshop served the preparing works to execute the ESOREX study also in ten Central and Eastern European countries. In order to establish the necessary contacts and to prepare the co-operation with the respective institutions of these states, the BfS organised, together with the State Office for Nuclear Safety of the Czech Republic, an international introductory workshop in Prague in September 1998. The proceedings reflect the presentations of the participants and the results of the discussions. (orig.)

    Directory of Open Access Journals (Sweden)

    Noemi Lendvai

    2005-03-01

    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.

    More than a decade after the start of the transition process, unemployment rates remain in the double digits in a number of Central and Eastern European countries. That unemployment rates have failed to decline, even in countries experiencing good growth, is puzzling. In this paper the authors examine three interrelated questions: How has the transition from central planning to market economies affected labor market performance? How have labor market institutions and policies influenced devel...

    Full Text Available The paper resumes a topic the author approached in severa[ instances beginning with 1987: some specific terms referring to the semantic sphere Herrscherschafi. In Romanian, ban, jupîn, stăpîn and probably also cioban reflect the indigenous Thracian substratum; these forms also reflect the archaic Indo-European Herrschersujfzx -n-. In Slavic, their equivalent forms ban, župan and stopan reflect either a Late Thracian or (Proto-Romanian influence. Equally Rom. vătaf reflects the substratum influence, whereas Slavic vatah, vatak, vataš reflects the same borrowing. On the other hand, Slavic gospodƄ, belongs to the archaic Proto-Slavic core elements, while cěsaŕƄ, reflect a Germanic influence. Finally, Rom. boier is an East-Romance innovation derived from bou 'ox' and initially meant 'owner of cattle = rich man', a traditional association between cattle-owners and richness. The word had a large distribution from the early Middle Ages until late in the 20th century. In a paper written some 15 years ago (Paliga 1987, in Linguistica, Ljubljana 1 dared suggest that a series of Romanian and Slavic terms referring to social and political organisation, specifically ban (1 'master, local leader' and (2 'coin, money' (2nd sense derived from the lst one,jupîn (formerly giupîn 'a master', 'a master, a lord', cioban 'a shepherd', rather reflect a compact etymological group of Pre-Romance and Pre-Slavic origin (including cioban, incorrectly considered a Turkish influence, seemingly starting from the erroneous, but largely spread hypothesis that intervocalic -b- in Romanian would rather suggest a newer origin 1 .

    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.

  15. Spirometry reference equations for central European populations from school age to old age.

    Directory of Open Access Journals (Sweden)

    Mascha K Rochat

    Full Text Available BACKGROUND: Spirometry reference values are important for the interpretation of spirometry results. Reference values should be updated regularly, derived from a population as similar to the population for which they are to be used and span across all ages. Such spirometry reference equations are currently lacking for central European populations. OBJECTIVE: To develop spirometry reference equations for central European populations between 8 and 90 years of age. MATERIALS: We used data collected between January 1993 and December 2010 from a central European population. The data was modelled using "Generalized Additive Models for Location, Scale and Shape" (GAMLSS. RESULTS: The spirometry reference equations were derived from 118'891 individuals consisting of 60'624 (51% females and 58'267 (49% males. Altogether, there were 18'211 (15.3% children under the age of 18 years. CONCLUSION: We developed spirometry reference equations for a central European population between 8 and 90 years of age that can be implemented in a wide range of clinical settings.

    Klose, Martin; Damm, Bodo; Kreuzer, Thomas

    2016-04-01

    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

    2011-04-01

    Full Text Available The aim of the work was to estimate the specific role that Central European botanic gardens play in the dispersal of alien plants, which results from the wide variety of plants cultivated in the gardens and regular international exchange of plant material between these institutions. We compared the results of recent field studies (in eight Polish botanic gardens and a review of older literature data and herbarium collections (from Central European botanic gardens. We found that in Poland the proportion of botanic garden escapes was lower (3% than would be expected from the "tens rule". Botanic gardens have played a considerable role in the development of the synanthropic flora of Central Europe in the last 200 years. We determined a group of species introduced through a network of botanic gardens and propose 5 theoretical patterns to describe the mode and pathways of the early stages of introduction of these species.

    Full Text Available Purpose – to analyze economic “shock” impact on Central and Eastern European countries’ sustainable economic development. Design/methodology/approach – Statistical data has been analyzed and sustainability theory has been applied to Central and Eastern European countries during economic downturn 2008 – 2012. Findings – Findings suggest that commonly used macroeconomic indicators do not reflect stable social economic development. Moreover, usually high economic growth during economic cycle is determent by high level of recession in economic cycle. This finding suggests that investors and other financial decision makers should take into account the sustainability of economic performance before taking financial decisions so that during financial economic recession could mitigate risks and loses in Central and Eastern European markets. Also the impact of intangible capital on countries’ sustainability was identified. There is a relationship between social and economic sustainability and intangible capital. Research limitations/implications – Research is applied in the theory of sustainable economic development. The economic and social performance is being considered in the research. Although the concept of sustainable economic development is quite controversial in scientific literature, the aspects of economic and social indicators are taken into account not considering much of ecological aspects of sustainable development. The research logic is based on sustainability as constant and smooth social and economic development than the development through natural limitations and human being needs combinations. Practical implications – Practical implications might be broad enough. Identification of reaction of economies to natural economic “shock” during economic downturn might be applied for governments decision makers, investors, banks, exporters to evaluate future economic financial decisions in Eastern and Central European

    2015-12-01

    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.

  2. ECONOMIC CONSEQUENCES OF PUBLIC DEBT. THE CASE OF CENTRAL AND EASTERN EUROPEAN COUNTRIES

    Directory of Open Access Journals (Sweden)

    2015-10-01

    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.

  4. 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)

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

    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 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 This paper analyses the determinants of the changes in the non-performing loan (NPL ratio in selected European emerging markets. The model was estimated on a panel dataset using a fixed effects estimator for seven Central and Eastern European (CEE countries between Q3:2007 and Q3:2012. The countries analyzed are Bulgaria, Croatia, Czech Republic, Hungary, Latvia, Romania and Slovakia. Although the literature on NPLs is quite extensive, this is the first empirical research on the countries of CEE region using aggregate, country-level data on problem loans. The results suggest that the primary cause of high levels of NPLs is the economic slowdown, which is evident from statistically significant and economically large coefficients on GDP, unemployment and the inflation 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.

    Full Text Available 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.

    Full Text Available This article investigates the scale of performance persistence in the Central European banking industry. Contrary to the existing literature, we test not only for the short-term performance persistence but we propose also a novel method of analyzing the long-term persistence. Using an extensive dataset, covering the 1992-2009 period, we establish that banks’ results are strongly persistent in two-years sub-periods as well as in the long-run. Moreover, we find that the strength of studied phenomenon is not significantly influenced by the macroeconomic environment, banks size and capital base and country-specific factors.

    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.

  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

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 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.

  5. Biomass potential assessment in Central and Eastern European Countries and opportunities for the Ukraine

    International Nuclear Information System (INIS)

    This paper discusses an approach to determine future biomass production potentials and cost supply curves based on a bottom-up approach. The approach uses detailed data on NUTS3 level (the nomenclature of territorial units for statistics (NUTS) provides a single, uniform breakdown of the economic territory of the European Union). The NUTS is the territorial classification for the compilation of regional accounts for Central and Eastern European Countries and results in biomass supply curves for different scenario conditions that could occur in a European setting. A first assessment of the Ukraine reveals that even with modest assumptions, the Ukrainian agricultural sector could supply 2,000 to 3,000 PJ of primary biomass per year on medium term (i.e. 2010-2015). Cost levels of liquid fuels produced from biomass (such as methanol or Fischer-Tropsch diesel) could end up around 6 Euro/GJ, which is about competitive with production costs of diesel and gasoline from mineral oil. Given the growing demand for biofuels in particular in the EU, biofuels could prove an extremely valuable export commodity for the Ukraine on shorter term already

  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.

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

    Directory of Open Access Journals (Sweden)

    Harasztos Ágnes

    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.

  10. 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.

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

    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.

  18. 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. (author)

  19. Determinants of FDI into Central and Eastern European Countries: Pull or Push Effect?

    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 The Silk Road Economic Belt, a strategic priority of the Chinese foreign policy in 2015, draws the attention to the countries of Central and Eastern Europe through the multiple benefits that it displays (investments, economic growth, trade between the countries along its corridors, job creation, infrastructure development, the strategic importance of being part of a grandiose multi-continental project. 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 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.

  2. Response of Central European Civil Security Systems to the Economic Crisis

    2015-12-01

    Full Text Available The public sector across Europe and elsewhere was affected by the economic crisis which fully unfolded in 2008. Considerable attention has been paid in the literature to the impacts of related budgetary cuts on social welfare, while some other areas remain largely under-researched. One of such areas is the so-called civil security, where no such endeavour has been attempted so far. In order to fill this gap, the paper examines the civil security systems of Central European countries (Czech Republic, Slovakia, Poland and Hungary, employing a qualitative comparative analysis. Taking on the systems perspective, the article inquires how the stress posed by the economic crisis affected the civil security systems - their structure and financing. The paper builds on the findings from a 7th FP project, “ANVIL”, within which data on civil protection and disaster management systems were collected.

  3. Effective Exchange Rates in Central and Eastern European Countries: Cyclicality and Relationship with Macroeconomic Fundamentals

    Directory of Open Access Journals (Sweden)

    Stavárek Daniel

    2015-06-01

    Full Text Available This paper examines the evolution of effective exchange rates in nine Central and Eastern European countries in terms of development trends, volatility and cyclicality. Consequently, it provides direct empirical evidence on the nature of the relationship between effective exchange rates and selected macroeconomic fundamentals, addressing a key precondition of numerous exchange rate determination models and theories that attempt to explain the role of exchange rates in the economy. The results suggest that flexible exchange rate arrangements are reflected in both nominal and real effective exchange rates having higher volatility and variability. Furthermore, the results provide mixed evidence in terms of intensity, direction and cyclicality, but show a weak correlation between exchange rates and fundamentals. Sufficiently high coefficients are found only for money supply. Consequently, using fundamentals for the determination of exchange rates and using the exchange rate to explain economic development may be of limited use for the countries analyzed.

  4. Sources of growth: Evidence from ten central and Eastern European countries during 1993-2008

    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.

  5. Analysis of Fertility in Ten Central And Eastern European Countries After 1989

    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.

    The increasing focus on infections in domestic cats ( Felis catus ) has raised questions about lungworm distribution in wild hosts. To enhance knowledge of the occurrence of lungworms in enzootic regions of central Italy, we examined the carcasses of 16 European wildcats ( Felis silvestris silvestris). Adult nematodes, feces, respiratory flushings, and pulmonary tissues were collected at necropsy and then microscopically and genetically analyzed. Fourteen wildcats had single or mixed lungworm species. Aelurostrongylus abstrusus was the most common parasite retrieved, followed by Troglostrongylus brevior. In addition, three specimens of Angiostrongylus chabaudi were found in the pulmonary arteries of one wildcat. Histologically, the most common lesions were a mild-to-severe chronic catarrhal bronchitis and a chronic interstitial pneumonia with smooth muscle hypertrophy, associated with T. brevior and A. abstrusus , respectively. These results demonstrate that the European wildcats may harbor several species of lungworms that may impair their health and welfare. Also, F. s. silvestris is a potential reservoir for respiratory nematodes in domestic cats. PMID:26967134

  7. A 'slow pace of life' in Australian old-endemic passerine birds is not accompanied by low basal metabolic rates.

    Life history theory suggests that species experiencing high extrinsic mortality rates allocate more resources toward reproduction relative to self-maintenance and reach maturity earlier ('fast pace of life') than those having greater life expectancy and reproducing at a lower rate ('slow pace of life'). Among birds, many studies have shown that tropical species have a slower pace of life than temperate-breeding species. The pace of life has been hypothesized to affect metabolism and, as predicted, tropical birds have lower basal metabolic rates (BMR) than temperate-breeding birds. However, many temperate-breeding Australian passerines belong to lineages that evolved in Australia and share 'slow' life-history traits that are typical of tropical birds. We obtained BMR from 30 of these 'old-endemics' and ten sympatric species of more recently arrived passerine lineages (derived from Afro-Asian origins or introduced by Europeans) with 'faster' life histories. The BMR of 'slow' temperate-breeding old-endemics was indistinguishable from that of new-arrivals and was not lower than the BMR of 'fast' temperate-breeding non-Australian passerines. Old-endemics had substantially smaller clutches and longer maximal life spans in the wild than new arrivals, but neither clutch size nor maximum life span was correlated with BMR. Our results suggest that low BMR in tropical birds is not functionally linked to their 'slow pace of life' and instead may be a consequence of differences in annual thermal conditions experienced by tropical versus temperate species.

    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.

    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.

    International Nuclear Information System (INIS)

    Full text: Initiated by the 5th Framework Programme of the European Commission, the European Nuclear Engineering Network (ENEN) is preparing the future European Nuclear Education schemes, degrees and requirements. To fully utilise the benefits of international co-operation and to promote the knowledge of students in nuclear engineering a 2,5 weeks course has been organised starting in spring 2003 and 2004. The main emphasis of the course is to perform reactor physics and kinetics experiments on three different research- and training reactors in three different locations (Vienna, Prague, Budapest). The experimental work is preceded by theoretical lectures aiming to prepare the students for the experiments (Bratislava). The students' work will be evaluated, and upon success the students will get a certificate. The finally accepted credit (ECTS) value will be determined by the students' home university. The ENEN-recommended value is between 6 and 8 ECTS. The more detailed description of the course will be given in the full paper. These courses are an upgraded result of a long-standing similar cooperation between the above-mentioned four institutions in Vienna, Prague, Bratislava and Budapest. The participation was opened to students of any European university, however, basic knowledge of reactor physics theory is requested, and this knowledge has to be attested by a professor of the student's home university. The number of participants is limited to 20. The application is subject of a selection procedure, and may be refused, if the course is already fully booked, or if the selection committee decides so, due to any reason. The quality control and accreditation of ENEN assures that the acquired knowledge of the participants will fulfil the requirements of the European Nuclear Education and fits in the European ECTS system. The cost of the 18 days course is in the range of 2000 Euros, which includes the tuition fee (utilization of 3 research reactors), textbooks, the

  12. Cladogenesis and morphological diversification in passerine birds.

    2004-07-15

    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

  15. 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

  17. Causes of the outbreak of the eurozone crises: the role of the USA and the European Central Bank monetary polic

    Directory of Open Access Journals (Sweden)

    Nalia Białek

    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.

  18. 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.

  19. 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 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.

Being in contact with Josef C Brada, Professor Emeritus, Editor of the journal Eastern European Economics (EEE, we realized that the paper had been sent to both journals, although first published in the EEE and then in our Journal. According to professor Brada’s and our analysis, the paper published in these two journals is exactly the same, except for minor differences in wording, most likely due to editing the text before publication. The outstanding differences are in the title and the fact that the paper published in our Journal has three authors and in EEE journal has two. Whatsoever, owing to the fact that the article had been sent to both journals almost at the same time, it had been impossible to find out the case during the review procedure. Due to this unpleasant situation, our Editorial Board would like to inform our valuable readers that all the necessary measures to retract the paper from our publication have been undertaken and according to publishing ethical principles, cooperation with the authors of the retracted paper have been stopped. Although, in this case neither EEE nor our Journal had any

    The factors that promote invasive behavior in introduced plant species occur across many scales of biological and ecological organization. Factors that act at relatively small scales, for example, the evolution of biological traits associated with invasiveness, scale up to shape species distributions among different climates and habitats, as well as other characteristics linked to invasion, such as attractiveness for cultivation (and by extension propagule pressure). To identify drivers of invasion it is therefore necessary to disentangle the contribution of multiple factors that are interdependent. To this end, we formulated a conceptual model describing the process of invasion of central European species into North America based on a sequence of "drivers." We then used confirmatory path analysis to test whether the conceptual model is supported by a statistical model inferred from a comprehensive database containing 466 species. The path analysis revealed that naturalization of central European plants in North America, in terms of the number of North American regions invaded, most strongly depends on residence time in the invaded range and the number of habitats occupied by species in their native range. In addition to the confirmatory path analysis, we identified the effects of various biological traits on several important drivers of the conceptualized invasion process. The data supported a model that included indirect effects of biological traits on invasion via their effect on the number of native range habitats occupied and cultivation in the native range. For example, persistent seed banks and longer flowering periods are positively correlated with number of native habitats, while a stress-tolerant life strategy is negatively correlated with native range cultivation. However, the importance of the biological traits is nearly an order of magnitude less than that of the larger scale drivers and highly dependent on the invasion stage (traits were associated

  3. DATA ISSUES IN TOTAL FACTOR PRODUCTIVITY BENCHMARKING: A CENTRAL EUROPEAN PERSPECTIVE

    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

    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.

    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

    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 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.

    18 chronic diseases were investigated in a population of 13,115 women living in six settings of West- (Avon UK, the Isle of Man), Central- (the Czech Republic and the Slovak Republic) and East-Europe (the Ukraine and Russia), that collaborate in the European Longitudinal Study of Pregnancy and Childhood (ELSPAC project). In prenatal questionnaires filled in after the first half of pregnancy, women reported 25,795 chronic diseases they ever suffered, out of them 11,188 having in present pregnancies. In the whole sample, lifelong prevalence was 11,2%, and prevalence in pregnancy 4,8% which means that 43,4% of all chronic diseases recurred in pregnancy. Up to mean age of 255 years in the whole sample, 39,6% women reported ever having indigestion, 29% back pains, 22,6% migraine, about 16% haemorrhoids, hay fever and eczema, about 10% varicose veins, anorexia nervosa, heavy depression and kidney diseases, over 5% rheumatism and 4% asthma. Less prevalent were infections of pelvic organs, febrile convulsions, joint inflammations, stomach ulcers, psoriasis and epilepsy. Lifetime prevalence of chronic diseases and their prevalence in pregnancy were the highest in the western zone and decreased eastwards, but recurrence grew in the opposite direction, being the highest in the eastern zone. The variation of each morbidity indicator is followed in all diseases between geographical zones as well as between individual study centres. PMID:18822844

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

    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.

    Full Text Available BACKGROUND: Neighborhood environment is an aspect that influences physical activity, mainly walking. Hence, built environment research may help to use environmental and policy strategies to increase physical activity. OBJECTIVE: This cross-sectional study aimed to investigate the association between perceived neighborhood environment and meeting the recommendation of at least 30 minutes of walking 5 or more days a week within active transportation and leisure-time domains in Central European older adults. METHODS: Four hundred and fifty six healthy ambulatory older adults filled out the modified and culturally adapted version of the Neighborhood Environment Walkability Scale (ANEWS for obtaining perceived environment information and the self-administrative long version of the International Physical Activity Questionnaire (IPAQ for assessing physical activity levels. RESULTS: Respondents living in high residential density neighborhoods (OR 1.87, living in flats (OR 2.09 and in location with ≤100,000 inhabitants (OR 1.63 were more likely to meet recommendation within walking for transportation. Owning a dog was associated with meeting recommendation within walking for leisure (OR 1.69. CONCLUSIONS: This study supported the specific impact of environment on meeting PA recommendations within transportation and leisure time walking in older adults. Out of all perceived neighborhood environmental attributes received from ANEWS questionnaire, only high residential density was positively associated with meeting recommendation within total walking and walking for transport.

    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 Objective To analyze the prevalence of diagnosed and suspected autoinflammatory diseases in Eastern and Central European (ECE countries, with a particular interest on the diagnostic facilities in these countries. Methods Two different strategies were used to collect data on patients with periodic fever syndromes from ECE countries- the Eurofever survey and collection of data with the structured questionnaire. Results Data from 35 centers in 14 ECE countries were collected. All together there were 11 patients reported with genetically confirmed familial Mediterranean fever (FMF, 14 with mevalonate-kinase deficiency (MKD, 11 with tumor necrosis factor receptor associated periodic syndrome (TRAPS and 4 with chronic infantile neurological cutaneous and articular syndrome (CINCA. Significantly higher numbers were reported for suspected cases which were not genetically tested. All together there were 49 suspected FMF patients reported, 24 MKD, 16 TRAPS, 7 CINCA and 2 suspected Muckle-Wells syndrome (MWS patients. Conclusions The number of genetically confirmed patients with periodic fever syndromes in ECE countries is very low. In order to identify more patients in the future, it is important to organize educational programs for increasing the knowledge on these diseases and to establish a network for genetic testing of periodic fever syndromes in ECE countries.

  13. The Impact of FDIs on Exports, and Export Competitiveness in Central and Eastern European Countries

    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.

    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

    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.

    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

    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

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 accident.

    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

    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.

  5. Charlemagne's summit canal: an early medieval hydro-engineering project for passing the Central European Watershed.

    Full Text Available 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.

    This paper estimates the medium-term determinants of the bilateral exchange rate variability and exchange rate pressures for 20 developed countries in the 1990s. The results suggest that optimum currency area criteria explain the dynamics of bilateral exchange rate variability and pressures, to a large extent. Next, we predict exchange rate volatility and pressures for the Central and Eastern European Countries (CEECs). We find that CEECs encounter exchange rate pressures approximately at the...

  19. 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.

    Initiated by the 5th Framework Program of the European Commission, the European Nuclear Engineering Network (ENEN) is preparing the future European Nuclear Education schemes, degrees and requirements. To fully utilize the benefits of international cooperation and to promote the knowledge of students in nuclear engineering a 2.5 weeks course has been held, both in spring 2003 and 2004. The main emphasis of the course is to perform reactor physics and kinetics experiments on three different research- and training reactors in three different locations (Vienna, Prague, Budapest). The experimental work is preceded by theoretical lectures aiming to prepare the students for the experiments (Bratislava). The students' work will be evaluated, and upon success the students will get a certificate. The finally accepted credit (ECTS) value will be determined by the students' home university. The ENEN-recommended value is between 6 and 8 ECTS. The more detailed description of the course will be given in the full paper. (author)

  5. Multilingual Maps of the Terrestrial Planets and their Moons: the East and Central European Edition

    Hargitai, H.; Berczi, Sz.

    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

    For five years, partnerships have existed between German nuclear power stations and nuclear power stations in the CIS and central European states with the object of increasing the nuclear safety and reliability of nuclear power stations through the interchange of experience by experts at all operational organisational levels. In this period, about 200 reciprocal meetings, exchanges of groups of experts, secondments into the partners' plants and seminars, of which about two-thirds have been in German nuclear power stations, have taken place. Improvements and a change in safety-responsibility awareness are clearly established. In this area, the partnerships have made an important contribution. (orig.)

    It is commonly held that the sun played a particularly important cultural role in later prehistoric Europe. The rise of a general European sun cult has even been suggested for the Bronze Age. During this period, the increasing use of special symbols assumed to represent the sun is easily discernible on different types of archaeological finds.

  13. Central-European Jesuit Scientists in China, and Their Impact on Chinese Science

    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.

    The core idea of this special issue is to investigate the link between identity and solidarity in the foreign policy of members of the European Union (EU).1 The term ‘identity’ has various definitions in external relations. In a classical way, one may state that ‘nationhood and national identity represent necessary myths which underpin foreign policy. They constitute the distinction between the “national community” which the government represents abroad and the foreigners with ...

    The Brachylaimoidea are digenean parasites of vertebrates, including humans, domestic animals, poultry and wild game. Numerous Brachylaimoidea, particularly adults of Brachylaima and Leucochloridium, are difficult to identify to species. We provide and analyse sequences of two nuclear (18S rDNA, ITS2) and two mitochondrial (CO1, ND1) DNA loci of central European species of the Brachylaimoidea, namely Leucochloridium holostomum, Leucochloridium paradoxum, Leucochloridium perturbatum, Leucochloridium subtilis, Leucochloridium vogtianum, Urotocus rossitensis, Urogonimus macrostomus, Michajlovia migrata, Leucochloridiomorpha lutea, Brachylaima arcuatus, Brachylaima fuscata and Brachylaima mesostoma. We identified three clades in the genus Leucochloridium, which do not correspond to the previously suggested subgenera Neoleucochloridium, Papilloleucochloridium and Leucochloridium. We reject classification of Urotocus and Urogonimus in Leucochloridiinae, and, instead, re-establish the subfamilies Urotocinae and Urogoniminae. We synonymize the genus Renylaima with the genus Brachylaima. We reject M. migrata as a member of Leucochloridiinae sensu stricto or Brachylaimidae suggested by some previous authors. We found that the previously sequenced Glaphyrostomum sp. does not cluster with any hitherto sequenced Brachylaimidae. We also provide comparative measurements of the examined central European Brachylaimoidea, address the the specificity of their localization in the host and discuss their host-specific prevalence and intensity of infections based on the extensive dataset of birds examined in 1962-2015.

    Despite the fact that mollusc species play an important role in many aquatic ecosystems, little is known about their biodiversity and conservation genetics. Freshwater pearl mussel (Margaritifera margaritifera L.) populations are seriously declining all over Europe and a variety of conservation programs are being established to support the remaining endangered central European populations. In order to provide guidelines for conservation strategies and management programs, we investigated the genetic structure of 24 freshwater pearl mussel populations originating from five major central European drainages including Elbe, Danube, Rhine, Maas and Weser, representing the last and most important populations in this area. We present a nondestructive sampling method of haemolymph for DNA analyses, which is applicable for endangered bivalves. The analyses of nine microsatellite loci with different levels of polymorphism revealed a high degree of fragmented population structure and very different levels of genetic diversity within populations. These patterns can be explained by historical and demographic effects and have been enforced by anthropogenic activities. Even within drainages, distinct conservation units were detected, as revealed from high F(ST) values, private alleles and genetic distance measures. Populations sampled close to contact zones between main drainage systems showed lowest levels of correct assignment to present-day drainage systems. Populations with high priority for conservation should not only be selected by means of census population size and geographical distance to other populations. Instead, detailed genetic analyses are mandatory for revealing differentiation and diversity parameters, which should be combined with ecological criteria for sustainable conservation and recovery programs.

    Study of the Central Extremadura batholith and shear zone, described for the first time herein, provides new insights into the tectonomagmatic evolution of the Ibero-Armorican arc. The main plutonic event may be closely related to intracontinental shear-zone development. The Central Extremadura shear zone may provide a model for the interpretation of collision structures related to the origin of the Ibero-Armorican arc.

    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.

    2011-01-01

    Full Text Available This article is dedicated to the development of European unity in Central Europe and Scandinavia as a mechanism of collective security and intergovernmental cooperation development. The cultural and historical features of Central Europe and Scandinavia emphasize the need for a comparative study into the European idea. This article considers the tendencies and factors which affected the development of the European idea in the framework of the post-war planning. This research sets out to compare and identify similar or analogous features and elements of the theoretical bases of movements for European unity in Central and Northern Europe. The author comes to the conclusion about the correlation between the “Europe of regions” model and the European unity concept. The ideas of Scandinavian and Central European integration rested on national, cultural and historical connections of the neighbouring countries were expected to constitute such formations, which contradicted and were opposed to by the theoretical framework of Western European integration. On the other hand, regional integration implied that a federation or union of the neighbouring states could be considered a step towards a more universal organisation, which would not mean the isolation of Scandinavia and Central Europe from the rest of the world. The theoretical and practical significance of this work lies in the comparative approach to the analysis of the phenomena which have been considered individually in the framework of historiography. It is the major contribution of the article to the research on history of ideas and European diplomacy. Moreover, the subject of research is immediately connected to the problem of security in the Baltic region and the Soviet factor, as well as political stereotypes produced in this field. The author employed historical comparative and inductive types of the historical typological method.

    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.

    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. PMID:26959221

    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

  14. 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.

    The migratory biology and connectivity of passerines remains poorly known, even for those that move primarily within the temperate zone. We used light-level geolocators to describe the migratory geography of a North American temperate migrant passerine. From February to March of 2010, we attached geolocator tags to 33 Golden-crowned Sparrows (Zonotrichia atricapilla) wintering on the central coast of California, USA, and recovered four tags the following winter (October to December 2010). We used a bayesian state-space model to estimate the most likely breeding locations. All four birds spent the breeding season on the coast of the Gulf of Alaska. These locations spanned approximately 1200 kilometers, and none of the individuals bred in the same location. Speed of migration was nearly twice as fast during spring than fall. The return rate of birds tagged the previous season (33%) was similar to that of control birds (39%), but comparing return rates was complicated because 7 of 11 returning birds had lost their tags. For birds that we recaptured before spring migration, we found no significant difference in mass change between tagged and control birds. Our results provide insight into the previously-unknown breeding provenance of a wintering population of Golden-crowned Sparrows and provide more evidence of the contributions that light-level geolocation can make to our understanding of the migratory geography of small passerines.

    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.

  5. 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

    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.

  18. 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 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

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.

  2. Influence of forest drainage on runoff: Main concepts and examples from central part of the USSR European territory

    International Nuclear Information System (INIS)

    An attempt is made to determine the impact of forest drainage on river runoff regime on the basis of experimental studies carried out in the central part of European USSR, on the results of hydrological modelling, and on other available data. It is shown that forest drainage can cause the increase in summer and winter low-flow values, except in extremely dry periods. The impact of forest drainage on snowmelt and rainfall flood peaks is ambiguous, and only hydrological modelling can ensure substantiated estimates for concrete river basins. Examples of numerical experiments for a catchment area of 870 km2 are given. The possible hydrological impact of post-reclamation changes that occur in drained areas is considered. 31 refs., 7 figs

    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.

    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.

  5. 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

    Drought may have severe impacts on many human activities. Understanding its spatio-temporal variations is thus very important in many research fields. On example of the Central Europe dataset we analyzed and compared some products based on drought analyses, which may help to answer important questions for impact studies: 1) evaluation of the added value coming from inclusion of spatial aspect (not only temporal one) in the drought analysis; 2) comparison of drought indices calculated from various number of available input meteorological elements (backwards into history less and less meteorological elements are available); 3) linking together meteorological drought with agriculture one. Basis for the study was production of gridded dataset of basic meteorological elements (daily minimum and maximum temperature, precipitation, sunshine duration, relative humidity and wind speed). From the station location time series in the period 1961-2013, gridded dataset was created applying geostatistical methods using both spatial and temporal aspects of the data (spacetime package under R). From such gridded dataset, SPEI (standardized precipitation evaporation index) was calculated using various approaches: Thornthwaite (potential evapotranspiration), Hargreaves and Penman-Monteith (reference evapotranspiration). The outputs were gridded datasets of the SPEIs that were then analyzed for the Central Europe both from temporal (based on station data) and spatial aspects. In order to estimate how this meteorological drought analysis may contribute to drought impact analysis (in our case we chose agriculture), we compared the results with the analysis coming from the agrometeorological drought monitoring system (based on SoilClim - dynamical model of soil water content) which is now used for drought monitoring and analysis in the Central Europe. Such comparison is important either for drought analysis in the past (when soil observations are not available) or also for future climate

  7. On the evolution of clutch size and nest size in passerine birds.

    1989-05-01

    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

  9. 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 results obtained confirm that both the return and the risk in some ofthe stock markets under analysis are influenced by the return of gold investment.

  12. 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.

    To assess the status of avian leukosis virus subgroup J (ALV-J) infection in passerine birds in China, 365 passerine birds collected from northeast China from 2011 to 2013 were tested, and two ALV-J strains were isolated from yellow-browed warbler and marsh tit. The 3'untranslated regions (3'UTRs) of the two strains were amplified, cloned, and sequenced, with the results showing that the 3'UTRs of the two strains contained multiple mutations and deletions, which are similar to viral strains isolated from Chinese layer chickens. These results demonstrate the presence of ALV-J in passerine birds and reveal the molecular characteristics of the 3'UTRs of ALV-J from passerine birds. PMID:25577165

  15. Inheritance of central neuroanatomy and physiology related to pheromone preference in the male European corn borer

    2010-09-01

    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

    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.

    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.

  19. The lending channel and budget balance: empirical evidences from Central and Eastern European economies

    2013-03-01

    Full Text Available The study aims to deepen the analysis on the indirect dependence of government budget balance on private sector credit flow in the countries of Central and Eastern Europe. The added value of this approach consists of two elements. First, the analysis suggests developing the traditional analytical framework of assessing risks to public finance stability by including second round effects of negative fiscal impulses on credit to private sector during recession periods. Second, the study provides empirical evidence on the importance of economic growth transmission channel for the impact of credit accelerator effects on primary deficit. At the same time, nonperforming loans channel proved to be insignificant, especially in relation to the persistency of last year’s budget deficit and the effects of budget allocations pro-cyclicality. However, loan portfolio quality seems to be more relevant in the case of public debt service, through its influence on the evolution of the yield on long-term government securities that is closely related to sovereign risk premium. Nevertheless, strengthening the financial safety net by the introduction of resolution funds will most probably break the link investors saw between credit portfolio quality and the impending increase in budget spending. This expected development across not only CEE countries, but at the EU level also, will facilitate the isolation of sovereign risk premium from non-performing loans’ dynamics.

  2. 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.

    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.

  6. 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.

    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.

  8. The wind and fire disturbance in Central European mountain spruce forests: the regeneration after four years

    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

  9. Effects of the 2003 European heatwave on the Central Mediterranean Sea surface layer: a numerical simulation

    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.

  10. Passerine birds breeding under chronic noise experience reduced fitness.

    Directory of Open Access Journals (Sweden)

    Julia Schroeder

    Full Text Available BACKGROUND: Fitness in birds has been shown to be negatively associated with anthropogenic noise, but the underlying mechanisms remain obscure. It is however crucial to understand the mechanisms of how urban noise impinges on fitness to obtain a better understanding of the role of chronic noise in urban ecology. Here, we examine three hypotheses on how noise might reduce reproductive output in passerine birds: (H1 by impairing mate choice, (H2 by reducing territory quality and (H3 by impeding chick development. METHODOLOGY/PRINCIPAL FINDINGS: We used long-term data from an island population of house sparrows, Passer domesticus, in which we can precisely estimate fitness. We found that nests in an area affected by the noise from large generators produced fewer young, of lower body mass, and fewer recruits, even when we corrected statistically for parental genetic quality using a cross-fostering set-up, supporting H3. Also, individual females provided their young with food less often when they bred in the noisy area compared to breeding attempts by the same females elsewhere. Furthermore, we show that females reacted flexibly to increased noise levels by adjusting their provisioning rate in the short term, which suggests that noise may be a causal factor that reduces reproductive output. We rejected H1 and H2 because nestbox occupancy, parental body mass, age and reproductive investment did not differ significantly between noisy and quiet areas. CONCLUSIONS/SIGNIFICANCE: OUR RESULTS SUGGEST A PREVIOUSLY UNDESCRIBED MECHANISM TO EXPLAIN HOW ENVIRONMENTAL NOISE CAN REDUCE FITNESS IN PASSERINE BIRDS: by acoustically masking parent-offspring communication. More importantly, using a cross-fostering set-up, our results demonstrate that birds breeding in a noisy environment experience significant fitness costs. Chronic noise is omnipresent around human habitation and may produces similar fitness consequences in a wide range of urban bird species.

  12. The breeding ranges of Central European and Arctic bird species move poleward.

    Directory of Open Access Journals (Sweden)

    Jon E Brommer

    Full Text Available BACKGROUND: Climatic warming predicts that species move their entire distribution poleward. Poleward movement of the 'cold' side of the distribution of species is empirically supported, but evidence of poleward movement at the 'warm' distributional side is relatively scarce. METHODOLOGY/PRINCIPAL FINDING: Finland has, as the first country in the world, completed three national atlas surveys of breeding birds, which we here use to calculate the sizes and weighted mean latitudes of the national range of 114 southern and 34 northern bird species during three periods (1974-1979; 1986-1989; 2006-2010, each denoting species presence in approximately 3 800 10 × 10 km2 squares. We find strong evidence that southern species (breeding predominantly in central Europe showed a latitudinal shift of 1.1-1.3 km/year poleward during all three pairwise comparisons between these atlases (covering 11, 20.5 and 31.5 years respectively. We find evidence of a latitudinal shift of 0.7-0.8 km/year poleward of northern boreal and Arctic species, but this shift was not found in all study periods and may have been influenced by increased effort put into the more recent surveys. Species showed no significant correlation in changes in range size and weighted mean latitude between the first (11 year and second (20.5 year period covered by consecutive atlases, suggesting weak phylogenetic signal and little scope of species characteristics in explaining latitudinal avian range changes. CONCLUSIONS: Extinction-driven avian range changes (at the 'warm' side of a species' distribution occur at approximately half the rate of colonisation-driven range changes (at the 'cold' side, and its quantification therefore requires long-term monitoring data, possibly explaining why evidence for such changes is currently rare. A clear latitudinal shift in an assemblage of species may still harbour considerable temporal inconsistency in latitudinal movement on the species level. Understanding

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).

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

    Directory of Open Access Journals (Sweden)

    Jiří Flousek

    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.

    FEKETE, István

    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.

    2009-06-01

    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.

    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

  1. European Union: European Commission studies and projects in the field of low level radioactive waste in countries of Central and Eastern Europe

    International Nuclear Information System (INIS)

    European Commission studies and projects in the nuclear sector are financed through a number of programmes and managed by various technical services in the Commission. The PHARE Nuclear Safety Programme is managed by the Task Force for Nuclear Issues (TFNI) of DG-Enlargement, which provided funding for projects in the then EU candidate countries in Central and Eastern Europe. Over the course of the PHARE Nuclear Safety Programme there were numerous projects in the field of LLW within the EU candidate countries. A useful, though not definitive, guide to projects before 1999 can be found in the Commission Report EUR 19154. As a result of the reorganization of the Commission's services in 2000, no PHARE multicountry programme was launched that year. TFNI restarted the nuclear safety programming activities in 2001. However, one project of interest was implemented during the intervening period: Project -006-RO/PHARESCR/ A6-01, Preparatory Measures for the Long-term Safety Assessment of the Low Level Radioactive Waste Repository Baita Bihor, Romania (completed in September 2001). Following the accession of the majority of these countries in 2004 there are no further PHARE annual programmes and the TFNI, along with DG-Enlargement, will be disbanded. The Euratom Research Framework Programme is managed by DG-Research (Unit JO4). Most of the research projects in the field of radioactive waste launched under the fifth Euratom Framework Programme were concerned with high level waste issues. Nonetheless, the work that has been undertaken within this programme could be of general interest to anyone in the radwaste sector. A complete summary of the various research conducted within the programme can be found in the following publication: Nuclear Fission and Radiation Protection Projects Selected for Funding 1999-2001, which is available at http://www.cordis.lu/fp5-euratom/src/lib_docs.htm. The first call for proposals for the sixth Framework Programme has now taken place. However

    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

    Full Text Available In this paper, we examine the attitudes towards gender roles among higher education students in a borderland Central-Eastern European region. We used the database of ‘The Impact of Tertiary Education on Regional Development’ project (N=602, 2010. We intend to determine what kind of attitudes towards gender roles the students identify themselves with, what affects these attitudes (gender, faculty type, social background of students, locality type, religiosity, and finally what kind of educational policy implications could be relevant concerning our findings. We have used cluster analysis and a logistic regression model, and formulated several hypotheses that were controlled by these methods. Our results show that there are a large number of students who belong to the more traditional attitude cluster in this region, but women more frequently identify themselves with modern gender roles than men do. The faculty-type effect has only been partly detected. We have found that with ‘male-dominated’ majors, both women and men identify themselves with more traditional attitudes and that with ‘female-dominated’ majors all students have more modern attitudes. The effect of social background is contradictory. Those whose parents had larger numbers of books had increased modern attitudes, but the factor ‘regular financial problems in the family’ also increased it. Our next result is that students who live in villages are not more traditional than others, because they live in cities during their studies. Our final result is that churchly religious students think more traditionally regarding gender roles than others do, but those who are religious in their own way do not.

    The central European flood in June 2013 once again revealed that complete flood protection is not possible. Inundations caused severe damage to buildings, infrastructure and agricultural lands. Official estimates of total damage in Germany amount to approx. 8bn € which is lower than the damage caused by the August 2002 flood - the most expensive natural hazard experienced so far in Germany. Repeated and long lasting precipitation in combination with extremely adverse preconditions induced a large scale flood event. In Germany, particularly the catchment areas of the Danube and Elbe were affected. The June 2013 flood has been the most severe flood event in terms of spatial extent and magnitude of flood peaks in Germany during the last 60 years. Large scale inundation occurred as a consequence of levee breaches near Deggendorf (Danube), Groß Rosenau and Fischbeck (Elbe). The flood has had a great impact on people, transportation and the economy. In many areas more than 50,000 thousand people were evacuated. Electrical grid and local water supply utilities failed during the floods. Furthermore, traffic was disrupted in the interregional transportation network including federal highways and long distance railways. CEDIM analysed and assessed the flood event within its current research activity on near real time forensic disaster analysis (CEDIM FDA: www.cedim.de). This contribution gives an overview about the CEDIM FDA analyses' results. It describes the key hydro-meteorological factors that triggered this extraordinary event and draws comparisons to major flood events in August 2002 and July 1954. Further, it shows the outcomes of a rapid initial impact assessment on the district level using social, economic and institutional indicators which are supplemented with information on the number of people evacuated and transportation disruptions and combined with the magnitude of the event.

    Within its current research activity on near real time Forensic Disaster Analysis (FDA), researchers from the Center for Disaster Management and Risk Reduction Technology (CEDIM) aim to identify major risk drivers and to understand the root causes of disaster and infer the implications for disaster mitigation. A key component of this activity is the development of rapid assessment tools which allow for a science based estimate of disaster impacts. The central European flood in June 2013 caused in Germany severe damage to buildings, infrastructure and agricultural lands and has had a great impact on people, transportation and the economy. In many areas thousands of people were evacuated. Electrical grid and local water supply utilities failed during the floods. Furthermore, traffic was disrupted in the interregional transportation network including federal highways and long distance railways. CEDIM analysed the impact and management of the flood event within an FDA activity. An analysis on the amount and spatial distribution of flood-related Twitter messages in Germany revealed a high interest in the flood in the social media. Furthermore, an analysis of the resilience of selected affected areas in Germany has been carried out to assess the impact of the flood on the district level. The resilience indicator is based on social, economic and institutional indicators which are supplemented with information on the number of people evacuated and transportation disruptions. Combined with the magnitude of the event, an index is calculated that allows for a rapid initial but preliminary estimate of the flood impact. Results show high resilience of the administrative districts along the Danube while heavy impacts are seen along the Mulde and Elbe.

    We investigate the paleostress fields which controlled the post-Variscan evolution of the Central European Basin System (CEBS). Therefore, field studies are carried out in the marginal areas of the CEBS where Late Palaeozoic and Mesozoic rocks of the basin fill are present in outcrops bearing the imprints of several deformation phases that affected the basin system since the latest Carboniferous. Field studies including structural analysis, measurement of fault-slip data and careful collection of kinematic indicators provide the data base for this study. In the case of polyphase tectonics, the chronology of successive events is deduced and the total fault population from each site is qualitatively divided into different subsets, each being consistent with one specific stress regime. Since the stratigraphy and evolution of the CEBS are well known, temporal and spatial correlations of paleostress orientations are possible. Beside cross-cutting relationships derived from outcrops, we apply different graphical and numerical methods to separate the faults into homogeneous subsets. Depending on (1) the nature of faults (i.e. neoformed or reactivated), (2) the distribution of fault-slip data and (3) the deformation style, the deviatoric stress tensor is calculated for each subset using either the Numeric Dynamic Analysis (Spang, 1972; Sperner et al., 1993) or the Multiple Inverse Method (Yamaji 2000). The results are obtained in terms of a reduced stress tensor, consisting of (1) the orientations of the three principal stress axes {sigma}{sub 1}, {sigma}{sub 2} and {sigma}{sub 3} with {sigma}{sub 1}{>=}{sigma}{sub 2}{>=}{sigma}{sub 3} and (2) the ratio of principal stress differences, R=({sigma}{sub 2}-{sigma}{sub 3})/({sigma}{sub 1}-{sigma}{sub 3}) with 1{>=}{phi}{>=}0.

    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

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

    Directory of Open Access Journals (Sweden)

    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.

    Three hundred and thirty specimens of 7 species of passerine birds from South Bass Island, Ottawa County, Ohio, were examined for helminth parasites. The total number of helminth specimens collected was 4,333. Forty-one helminth taxa were identified. Ten species of helminths were identified as having foci of infection on the island. An index of association for these 10 species is presented. The low association revealed between helminth species utilizing common species of intermediate hosts indicated that a single intermediate host specimen is likely to harbor infective stages of only one species of parasitic helminth. An index of similarity is presented to express the species importance relationships of the helminth faunas of the 7 species of birds: red-winged blackbirds (Agelaius phoeniceus), blue jays (Cyanocitta cristata), brown-headed cowbirds (Molothrus ater), common grackles (Quiscalus quiscula), house sparrows (Passer domesticus), starlings (Sturnus vulgaris), and robins (Turdus migratorius). The results reveal that competition between these avian species for invertebrate food resources helps to maximize the transmission of those helminth populations which utilize these same invertebrates as intermediate hosts. The aggregation of birds into mixed feeding flocks insures a heavy loading of the feeding grounds with agents infective for the invertebrate populations. PMID:1255354

    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

  12. 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.

    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

  14. 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.

  15. 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.

    Thirty-two immature common yellowthroats were used to evaluate three methods of attaching radio transmitters to the backs of small passerines: adhesive, velcro, and harness. There were no significant differences between the three methods; however, the adhesive method of transmitter attachment to small birds was found to be the preferred technique.

    Interspecific variation in sperm size is enigmatic, but generally assumed to reflect species-specific trade-offs in selection pressures. Among passerine birds, sperm length varies sevenfold, and sperm competition risk seems to drive the evolution of longer sperm. However, little is known about factors favouring short sperm or constraining the evolution of longer sperm. Here, we report a comparative analysis of sperm head abnormalities among 11 species of passerine bird in Chernobyl, presumabl...

    Mora, Miguel A

    2008-10-01

    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

    2015-02-01

    Full Text Available Even if intraspecific conflict is a well-known behaviour in birds, intraspecific killing among passerines is very rare in the literature. Cases of intraspecific predation among passerines constitute a very small percentage of published reports, and many of the cases are based on circumstantial evidence. In March 2013, we witnessed a group of House Sparrows (Passer domesticus kill a conspecific male adult in the village of Gonsans (France, Doubs department. During the reproductive season three explanations of others studies (lack of food, weak condition and territorial behaviour during could be relevant in our case. In conclusion, it appears that our observation is a very rare one and the second one for the House Sparrow.

DESIGN: Population-based, prospective, cohort study. METHODS: The Gutenberg Health Study (GHS cohort included 4,698 eligible enrollees of 5,000 subjects (age range 35-74 years who participated in the survey from 2007 to 2008. All participants underwent an ophthalmological examination including slitlamp biomicroscopy, intraocular pressure measurement, central corneal thickness measurement, fundus examination, and were given a questionnaire regarding glaucoma history. Furthermore, all subjects underwent fundus photography and visual field testing using frequency doubling perimetry. RESULTS: Mean CCT was 557.3 ± 34.3 µm (male and 551.6±35.2 µm in female subjects (Mean CCT from right and left eyes. Younger male participants (35-44 years presented slightly thicker CCT than those older. We noted a significant CCT difference of 4 µm between right and left eyes, but a high correlation between eyes (Wilcoxon test for related samples: p<0.0001. Univariable linear regression stratified by gender showed that IOP was correlated with CCT (p<0.0001. A 10 µm increase in CCT led to an increase in IOP between 0.35-0.38 mm Hg, depending on the eye and gender. Multivariable linear regression analysis revealed correlations between gender, spherical equivalent (right eyes, and CCT (p<.0001 and p=0.03, respectively. CONCLUSIONS: We observed positive correlations between CCT and IOP and gender. CCT was not correlated with age, contact lens wear, positive family history for glaucoma, lens status, or iris colour.

    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...

  2. Rat eradication and the resistance and resilience of passerine bird assemblages in the Falkland Islands.

    2015-05-01

    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

  4. Still an Awkward Class: Central European post-peasants at home and abroad in the era of neoliberalism

    Directory of Open Access Journals (Sweden)

    Chris Hann

    2013-01-01

    Full Text Available The paper builds on the author’s intimate knowledge of Eastern European village life over four decades. Before, during, and after socialism, villagers (“peasants” have always been incorporated into wider structures, while at the same time challenging standard social science theories. Their greater ability to reproduce themselves “outside the market” is the basis of their distinctiveness; this corresponds to a persisting distinction between town and countryside and has implications for political mobilization. The paper develops binary comparisons at two levels: first, between capitalist and socialist paths of rural development; second, within the latter, between the productive symbiosis accomplished in socialist Hungary and the stagnation of non-collectivized Poland. Some of these latter contrasts have persisted in new forms in the era of EU membership. Finally, the author expresses some personal nostalgia for the days when rural community studies constituted the bedrock of ethnographic writing about this region.

  5. The triad of success in personalised medicine: pharmacogenomics, biotechnology and regulatory issues from a Central European perspective.

    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

    2008-01-01

    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.

  8. Distribution and behaviour of passerines around peregrine Falco peregrinus eyries in western Greenland

    Science.gov (United States)

    Meese, R.J.; Fuller, M.R.

    1989-01-01

    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.

  9. Effects of solar UV-B radiation on growth, flowering and yield of central and southern European bush bean cultivars (Phaseolus vulgaris L.)

    International Nuclear Information System (INIS)

    Different cultivars of bush beans (Phaseolus vulgaris L.) originating from Central and Southern Europe were grown from July to August/September 1993 up to 7 and 8 weeks, respectively, in two greenhouses covered by different UV-B-absorbing (280-320nm) plastic foils. By using the ambient UV-B radiation of the southern location (Portugal, 38.7°N, 9.1°W) in one of the greenhouses as intense UV-B radiation compared to the reduced radiation in the second greenhouse at the same place, a difference in UV-B of about 8–10% was simulated. All cultivars examined showed significant reductions in height of up to 31,8% in most growth phases under intense UV-B. Also fresh and dry weight as well as leaf area were reduced under intense UV-B in the cultivars Purple Teepee, Cropper Teepee and Goldstrahl, and in early growth phases also in Coco bianco, but with ongoing development this cultivar caught up. Cultivars Hilds Maja, Primel, Manata and Cannellino exhibited no UV-B effects on weight and leaf area. A flowering delay of up to 1 day was observed under intense UV-B in several cultivars. Probably due to this delay the yield (fresh weight of fruits) decreased in all cultivars up to 55% under intense UV-B at harvest time, while the potential yield (sum of buds, opened flowers and fruits) was reduced only in the cultivars Cropper Teepee, Purple Teepee, Cannellino and Goldstrahl. The UV-sensitivity index (UVSI) calculated according to the UV induced changes in growth, dry weight and yield at the second harvest date has shown that all cultivars are UV-sensitive, however the index was numerically higher for Southern European cultivars (average = 2.5) than for Central European ones (average = 2.3) which means that the first group was slightly less UV-sensitive than the second.

Simultaneously, we used RFLP to detect the c.1331+2T>C mutation in 85 Hungarian deaf Roma patients, control groups of 702 normal hearing Romanies from both countries and 375 hearing impaired Slovak Caucasians. We analyzed the haplotype using 21 SNPs spanning a 5.34Mb around the mutation c.1331+2T>C.One pathogenic mutation (c.1331+2T>C was identified in 12 homozygous hearing impaired Roma patients. Allele frequency of this mutation was higher in Hungarian (10% than in Slovak (3.85% Roma patients. The identified common haplotype in Roma patients was defined by 18 SNP markers (3.89 Mb. Fourteen common SNPs were also shared among Pakistani and Roma homozygotes. Biallelic mutation carriers suffered from prelingual bilateral moderate to profound sensorineural hearing loss.We demonstrate different frequencies of the c.1331+2T>C mutation in hearing impaired Romanies from 3 Central European countries. In addition, our results provide support for the hypothesis of a possible common ancestor of the Slovak, Hungarian and Czech Roma as well as Pakistani deaf patients. Testing for the c.1331+2T>C mutation may be recommended in GJB2 negative Roma cases with early-onset sensorineural hearing loss.

  11. Elements of European Political Culture in the Central Asian National Outskirts of the Russian Empire: Perception Specifics of Foreign Cultural Innovations (late 19th – early 20th

    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.

  12. Contribution of ambient ozone to Scots pine defoliation and reduced growth in the Central European forests: A Lithuanian case study

    International Nuclear Information System (INIS)

    The study aimed to explore if changes in crown defoliation and stem growth of Scots pines (Pinus sylvestris L.) could be related to changes in ambient ozone (O3) concentration in central Europe. To meet this objective the study was performed in 3 Lithuanian national parks, close to the ICP integrated monitoring stations from which data on meteorology and pollution were provided. Contribution of peak O3 concentrations to the integrated impact of acidifying compounds and meteorological parameters on pine stem growth was found to be more significant than its contribution to the integrated impact of acidifying compounds and meteorological parameters on pine defoliation. Findings of the study provide statistical evidence that peak concentrations of ambient O3 can have a negative impact on pine tree crown defoliation and stem growth reduction under field conditions in central and northeastern Europe where the AOT40 values for forests are commonly below their phytotoxic levels. - Peak ozone concentrations is one of the key factors affecting Scots pine trees

  13. Impact of southern and central European land surface heating induced by greenhouse warming on the atmospheric circulation

    International Nuclear Information System (INIS)

    Full text: A robust result of greenhouse warming runs with global climate models is the depletion of soil moisture in southern and central Europe in summer. This leads to a strong increase in surface temperatures as a result of the accompanying reduction of the surface cooling by evaporation. In a series of sensitivity experiments with the EC-EARTH climate model we investigate the effect of this enhanced warming on the atmospheric circulation. EC-EARTH is a coupled climate model jointly developed by the EC-EARTH consortium and is based on the integrated forecast model of the ECMWF. The sensitivity experiments are designed to test the hypothesis that the enhanced summer surface easterlies over central Europe that are found in many recent climate scenario simulations are mainly due to the development of a heat low over the Mediterranean region in response to the enhanced warming of North Africa and Southern Europe. In the experiments with EC-EARTH the land surface temperature is artificially enhanced by increasing the downward surface solar radiation. This is done in order to enable the soil moisture to respond in a dynamically consistent way to the increase in surface land temperature. A similar approach has been successfully used in a previous study to show that an enhanced Sahara heating results in a deepening of the Sahara low with consequences for the Sahel rainfall. (author)

    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.

    Full Text Available This article is dedicated to the development of European unity in Central Europe and Scandinavia as a mechanism of collective security and intergovernmental cooperation development. The cultural and historical features of Central Europe and Scandinavia emphasize the need for a comparative study into the European idea. This article considers the tendencies and factors which affected the development of the European idea in the framework of the post-war planning. This research sets out to compare and identify similar or analogous features and elements of the theoretical bases of movements for European unity in Central and Northern Europe. The author comes to the conclusion about the correlation between the “Europe of regions” model and the European unity concept. The ideas of Scandinavian and Central European integration rested on national, cultural and historical connections of the neighbouring countries were expected to constitute such formations, which contradicted and were opposed to by the theoretical framework of Western European integration. On the other hand, regional integration implied that a federation or union of the neighbouring states could be considered a step towards a more universal organisation, which would not mean the isolation of Scandinavia and Central Europe from the rest of the world. The theoretical and practical significance of this work lies in the comparative approach to the analysis of the phenomena which have been considered individually in the framework of historiography. It is the major contribution of the article to the research on history of ideas and European diplomacy. Moreover, the subject of research is immediately connected to the problem of security in the Baltic region and the Soviet factor, as well as political stereotypes produced in this field. The author employed historical comparative and inductive types of the historical typological method.

    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.

    2010-09-01

    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.

    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.

  20. Effects of solar UVB radiation on growth, flowering and yield of central and southern European maize cultivars (Zea mays L.)

    International Nuclear Information System (INIS)

    Different cultivars of maize (Zea mays L.) originating from Central and South Europe were grown from June to September 1994 for 16 weeks in two greenhouses covered with different UVB-absorbing (280-320 nm) plastic foils. Using the ambient UVB radiation level of a southern location (Portugal, 38.7oN) in one of the greenhouses as an enhanced radiation compared to the reduced radiation in the second greenhouse, an increase of about 12% of UVB was simulated. Six of the eight cultivars examined showed significant reductions in height of up to 18.9% at all developmental stages under increased UVB. In contrast to this, the fresh and dry weight as well as the leaf area was reduced under UVB only at early developmental stages, but with ongoing development the UVB stressed plants caught up. The total content of absorbing compounds of the maize cultivars was completely unaffected by UVB. A flowering delay up to a maximum of 5 days was observed under higher UVB in several cultivars. Probably due to this delay in the cob development the yield decreased to 27.7% under higher UVB at the first harvest after 12 and 14 weeks, whereas at the second harvest after 14 and 16 weeks yield reduction levelled off.

    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

    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

    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.

    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. PMID:24832837

    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.

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

    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.

    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

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

    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

    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

    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.

  17. 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)

  18. Nuclear policies in Central Europe. Environmental policy and enlargement of the European Union: Austria's policies towards Nuclear Reactors in neighboring countries

    International Nuclear Information System (INIS)

    Austria's anti-nuclear policies are rooted in the successful anti-nuclear referendum on the Zwentendorf nuclear power plant (Lower Austria) in 1978 and the great impact of the Chernobyl catastrophe on Austria in 1986. Since about 1990, official Austria has pursued anti-nuclear policies not only at home but also abroad. In particular, reactors in Central and Eastern European Countries (CEEC) are the focal points of Austria's foreign anti-nuclear policies. Strategies include increasing nuclear safety, promoting energy efficiency and sustainable energy sources (such as renewable resources), and extending international legal frameworks to account for nuclear safety. Involvement in domestic energy issues in other countries is not an easy task, and while Austrian policy makers have had some success in increasing awareness of nuclear safety in Europe, they have also made a number of strategic mistakes. Notwithstanding real and substantiated concerns regarding nuclear safety, Austrian policies have lost credibility during recent years. This book explores the history and the development of Austrian anti-nuclear policies, and discusses the political economy of such policies. Particular emphasis is laid on the 2002 referendum against the Temelin reactor in the neighboring Czech Republic. (orig.)

    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. ??

    Geographic variation in vocalizations is widespread in passerine birds, but its origins and maintenance remain unclear. One hypothesis to explain this variation is that it is associated with geographic isolation among populations and therefore should follow a vicariant pattern similar to that typically found in neutral genetic markers. Alternatively, if environmental selection strongly influences vocalizations, then genetic divergence and vocal divergence may be disassociated. This study compared genetic divergence derived from 11 microsatellite markers with a metric of phenotypic divergence derived from male bower advertisement calls. Data were obtained from 16 populations throughout the entire distribution of the satin bowerbird, an Australian wet-forest-restricted passerine. There was no relationship between call divergence and genetic divergence, similar to most other studies on birds with learned vocalizations. Genetic divergence followed a vicariant model of evolution, with the differentiation of isolated populations and isolation-by-distance among continuous populations. Previous work on Ptilonorhynchus violaceus has shown that advertisement call structure is strongly influenced by the acoustic environment of different habitats. Divergence in vocalizations among genetically related populations in different habitats indicates that satin bowerbirds match their vocalizations to the environment in which they live, despite the homogenizing influence of gene flow. In combination with convergence of vocalizations among genetically divergent populations occurring in the same habitat, this shows the overriding importance that habitat-related selection can have on the establishment and maintenance of variation in vocalizations.

    In early June 2013, severe flooding hit Central and Eastern Europe, causing extensive damage, in particular along the Danube and Elbe main watersheds. The situation was particularly severe in Eastern Germany, Austria, Hungary and the Czech Republic. Based on the Post Event Review Capability (PERC) approach, developed by Zurich Insurance's Flood Resilience Program to provide independent review of large flood events, we examine what has worked well (best practice) and opportunities for further improvement. The PERC overall aims to thoroughly examine aspects of flood resilience, flood risk management and catastrophe intervention in order to help build back better after events and learn for future events. As our research from post event analyses shows a lot of losses are in fact avoidable by taking the right measures pre-event and these measures are economically - efficient with a return of 4 Euro on losses saved for every Euro invested in prevention on average (Wharton/IIASA flood resilience alliance paper on cost benefit analysis, Mechler et al. 2014) and up to 10 Euros for certain countries. For the 2013 flood events we provide analysis on the following aspects and in general identify a number of factors that worked in terms of reducing the loss and risk burden. 1. Understanding risk factors of the Central European Floods 2013 We review the precursors leading up to the floods in June, with an extremely wet May 2013 and an atypical V-b weather pattern that brought immense precipitation in a very short period to the watersheds of Elbe, Donau and partially the Rhine in the D-A-CH countries and researched what happened during the flood and why. Key questions we asked revolve around which protection and risk reduction approaches worked well and which did not, and why. 2. Insights and recommendations from the post event review The PERC identified a number of risk factors, which need attention if risk is to be reduced over time. • Yet another "100-year flood" - risk

    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.

    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.

    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 116 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).

  10. Mercury concentrations in Bicknell's thrush and other insectivorous passerines in Montane forests of northeastern North America.

    Anthropogenic input of mercury (Hg) into the environment has elevated risk to fish and wildlife, particularly in northeastern North America. Investigations into the transfer and fate of Hg have focused on inhabitants of freshwater aquatic ecosystems, as these are the habitats at greatest risk for methylmercury (MeHg) biomagnification. Deviating from such an approach, we documented MeHg availability in a terrestrial montane ecosystem using a suite of insectivorous passerines. Intensive and extensive sampling of Bicknell's thrush (Catharus bicknelli) indicated significant heterogeneity in MeHg availability across 21 mountaintops in northeastern North America. Southern parts of the breeding range tended to be at greater risk than northern parts. Mean blood Hg concentrations for Bicknell's thrush at 21 distinct breeding sites ranged from 0.08 to 0.38 ug/g (ww) and at seven Greater Antillean wintering sites ranged from 0.03 to 0.42 ug/g (ww). Overall concentrations were significantly greater in wintering than in breeding areas. Mercury exposure profiles for four passerine species on Mt. Mansfield, Vermont indicated greatest MeHg uptake in Bicknell's thrush and yellow-rumped warbler (Dendroica coronata) and lowest in blackpoll warbler (Dendroica striata) and white-throated sparrow (Zonotrichia albicollis). The MeHg and total Hg ratio in blood in these four species was nearly 1:1. There was no correlation between blood and feather Hg concentrations in breeding Bicknell's thrush, in part because of apparent retention of winter Hg body burdens, within-season variation of MeHg availability, and confounding factors such as influences from age. Adult thrushes had significantly higher concentrations of feather Hg than did young-of-the-year. Although individual patterns of inter-year feather Hg concentrations were disordered, some individuals exhibited bioaccumulation of MeHg. Female blood Hg concentrations were significantly lower than males', in part because females have

We used data compiled from 116 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

    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

    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. PMID:25214487

    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.

    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

    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

    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

    2011-07-01

    This is a systematic review examining the management of opioid-induced central side effects. It has been conducted as part of a larger European Palliative Care Research collaborative review into the use and role of opioids in cancer pain. The review process identified 26 studies that met the inclusion criteria. The overall quality of the data was low and the few recommendations that can be made are weak and require confirmatory studies. The main central side effects examined were sedation, cognitive failure, sleep disturbance and myoclonus. Overall there is limited evidence for the use of methylphenidate in counteracting opioid-induced sedation and cognitive disturbance. No clear recommendations can be made concerning other individual drugs for the management of any of the central side effects examined. Given the lack of available data from this review there need to be further prospective controlled trials to confirm or refute these findings. PMID:20870687

  4. 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.

  5. Regionalism versus integration of the EU electricity market : An open debate from the comparative and prospective analysis of regulatory regimes in the central European countries

    International Nuclear Information System (INIS)

    The failure of integration of 25 national energy markets into an unique one has been clearly expressed by the European Commission in its last benchmarking report. This working paper investigate the question of the more appropriate and realistic market design to limit perverse effects linked to the gaps between Western and Eastern European electricity markets. The paper consists in comparing electricity regulations per segment of the value chain in the CECs (Czech Republic, Hungary, Poland, Slovakia) characterized by industrial structures stemming from the socialism. Our regulatory approach and the example of South-East Europe support the idea of regionalism as an interim stage towards a final integrated European market. This regionalism based on the Standard Market Design concept, with flexible principles, and simultaneously combined to national reforms would seem to be a ''key of success''. (Author)

    2003-01-01

    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.

    Physiological adaptation arises from several fundamental sources of phenotypic variation. Most analyses of metabolic adaptation in birds have focused on the basal metabolic rate (BMR), the lower limit of avian metabolic heat production. In this study, we investigated thermoregulation in three passerine species; the yellow-billed grosbeak Eophona migratoria, white-rumped munia Lonchura striata and black-throated bushtit Aegithalos concinnus, in Wenzhou, China. Metabolic rate was measured using the closed-circuit respirometer containing 3.5 L animal chambers. Body temperature (Tb) was measured during metabolic measurements using a lubricated thermocouple. The minimum thermal conductance of these species was calculated by measuring their Tb and metabolic rates. The yellow-billed grosbeak remained largely normothermic, and the white-rumped munia and black-throated bushtit exhibited variable Tb at ambient temperatures (Ta). Mean metabolic rates within thermal neutral zone were 2.48±0.09 O2(mL)/g/h for yellow-billed grosbeaks, 3.44±0.16 O2(mL)/g/h for white-rumped munias, and 3.55±0.20 O2(mL)/g/h for black-throated bushtits, respectively. Minimum thermal conductance of yellow-billed grosbeak, white-rumped munia and black-throated bushtit were 0.13±0.00, 0.36±0.01, and 0.37±0.01 O2(mL)/g/h/℃, respectively. The ecophysiological characteristics of these species were:(1) the yellowbilled grosbeak had relatively high Tb and BMR, a low lower critical temperature and thermal conductance, and a metabolic rate that was relatively insensitive to variation in Ta; all of which are typical of cold adapted species and explain its broader geographic distribution; (2) the white-rumped munia and blackthroated bushtit had high thermal conductance, lower critical temperature, and relatively low BMR, all which are adapted to warm environments where there is little selection pressure for metabolic thermogenesis. Taken together, these data illustrate small migratory and resident

    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

    Klebsiella pneumoniae is considered one of the most important Gram-negative opportunistic pathogens. The contact between humans and birds poses health risks to both. The aim of this study was to investigate the resistance and virulence of K. pneumoniae isolates from psittacines and passerines, seized from illegal trade in Brazil. We analysed 32 strains isolated from birds of the orders Psittaciformes and Passeriformes by polymerase chain reaction (PCR) for virulence factor genes. Antibiotic resistance was assessed by disk diffusion assay and PCR. The results indicated that fimH (100%), uge (96.8%), kfu (81.2%) and irp-2 (68.7%) were the most common virulence genes, followed by kpn (46.8%), K2 (43.7%), mrkD (34.3%) and iroN (15.6%). The combination of virulence genes resulted in a great diversity of genotypes and the heterogeneity of the strains is also confirmed in the analysis by amplified fragment length polymorphism. The susceptibility profiles of the K. pneumoniae showed 25% of multiple antibiotic resistance strains. We identified seven strains that presented non-extended spectrum beta lactamase blaSHV variants SHV-1 and SHV-11 and one strain positive to the blaTEM-1 gene. Plasmid-mediated quinolone resistance was present in 10 strains (10/32). The data obtained in this study reveal the pathogenic potential of this pathogen and highlight the need for surveillance and monitoring. PMID:26813537

    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.

    International Nuclear Information System (INIS)

    The use of passerine species as bioindicators of metal bioaccumulation is often underutilized when examining the wildlife habitat value of polluted sites. In this study we tested feathers of nestlings of two common bird species (house wren and American robin) for accumulation of Pb, Zn, As, Cr, Cu, Fe in comparison of a polluted, urban brownfield with a rural, unpolluted site. House wren nestlings at the study site accumulated significantly greater concentrations of all target metals except Zn. At the polluted site we found significant species differences of metal concentrations in feathers, with house wrens accumulating greater concentrations of Pb, Fe, and Zn but slightly lesser accumulations of Cr and Cu than American robins. Although house wren nestlings demonstrated significant accumulation of metals, these concentrations showed little effect on size metrics or fledge rates during the breeding season compared to nestlings from the control site. - Nestlings of birds in an urban brownfield accumulated soil contaminants but did not show signs of reduced breeding success or growth.

  3. 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.

  4. 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

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

    José L Tellería

    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.

  12. 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

  14. 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.

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

    Science.gov (United States)

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

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

    Riffler, Michael; Wunderle, Stefan

    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

  1. Comparative ecosystem-atmosphere exchange of energy and mass in a European Russian and a central Siberian bog I. Interseasonal and interannual variability of energy and latent heat fluxes during the snowfree period

    International Nuclear Information System (INIS)

    Energy and latent heat fluxes λE were measured over ombrotrophic bogs in European Russia (Fyodorovskoye) and in central Siberia (Zotino) using the eddy covariance technique, as part of the EuroSiberian Carbonflux Project. The study covered most of the snowfree periods in 1998, 1999 and 2000; in addition some data were also collected under snow in early spring and late autumn 1999 and 2000. The snowfree period in European Russia exceeds the snowfree period in central Siberia by nearly 10 weeks. Marked seasonal and interannual differences in temperatures and precipitation, and hence energy partitioning, were observed at both sites. At both bogs latent heat fluxes ( E) exceeded sensible heat fluxes (H) during most of the snowfree period: maximum λE were between 10 and 12 MJ/m2/d while maximum H were between 3 and 5 MJ/m2/d. There was a tendency towards higher Bowen ratios at Fyodorovskoye. Net radiation was the most influential variable that regulated daily evaporation rates, with no obvious effects due to surface dryness during years with exceptionally dry summers. Total snowfree evaporation at Fyodorovskoye (320 mm) exceeded totals at Zotino (280 mm) by 15%. At the former site, evaporation was equal to or less than precipitation, contrasting the Zotino observations, where summer evaporation was distinctly higher than precipitation. During the entire observation period evaporation rates were less than 50% of their potential rate. These data suggest a strong 'mulching' effect of a rapidly drying peat surface on total evaporation, despite the substantial area of free water surfaces during parts of the year. This effect of surface dryness was also observed as close atmospheric coupling

    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.

    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.

    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.

    In May/June 2013, heavy precipitation hit Central Europe, triggering damaging floods both on the Danube and on Elbe basins. In this study, we perform a detailed analysis of the synoptic development of the event based on an ensemble of regional climate model simulations performed with the COSMO-CLM. Simulations are performed with reanalysis data boundary conditions in multiple set-ups and horizontal resolutions of 0.375° and 0.125°. In particular, the aim is to identify potential moisture sources, and how they contributed to the event quantitatively. A control simulation with undisturbed (reanalysis) boundary conditions and sensitivity experiments with modified evaporation characteristics are performed to distinguish the role of moisture evaporated from marine and land areas. To keep the structure of the simulations close to reality as possible, spectral nudging is applied on the upper level atmospheric wind fields. For all simulations, the synoptic situations and cyclone tracks are evaluated against an independent reanalysis dataset, and simulated precipitation amounts are validated against E-OBS precipitation data. In general, the upper level atmospheric characteristics, which trigger the cyclones, are similar in the simulations compared to the reanalysis. Moreover, the time evolution of the precipitation event is well simulated. Nevertheless there are some differences in the spatial and temporal distribution of the precipitation. In both, the reanalysis and the control simulation, the cyclones relevant for this event were moving westward (retrograde movement), counterclockwise from the Mediterranean region over Eastern Europe towards the northern slopes of the Alps. The pre-existing moist soil over East and Central Europe and the circulation associated with the cyclones contributed to intense evapotranspiration, and thus the westward propagating cyclones brought a lot of moisture along their tracks towards Central Europe. The sensitivity studies performed with

    We have analyzed the thermochemical structure of the mantle in Central Europe, a complex area with a highly heterogeneous lithospheric structure reflecting the interplay of contraction, strike slip, subduction, and extension tectonics. Our modeling is based on an integrative 3-D approach (LitMod) that combines in a self-consistent manner concepts and data from thermodynamics, mineral physics, geochemistry, petrology, and solid Earth geophysics. This approach minimizes uncertainties of the estimates derived from modeling of various data sets separately. To further constrain our 3-D model we have made use of the vast geophysical and geological data (2-D and 3-D, shallow/crustal versus deep lithospheric experiments) based on experiments performed in Central Europe in the past decades. Given the amount and the different nature/resolution of the available constraints, one of the most challenging tasks of this study was to consistently combine them, finding a trade-off between all local and regional data sets available in a way that (i) preserves as many structural details as possible and (ii) summarizes those data sets into a single robust regional model. The resulting P/T-dependent mantle densities are in LitMod 3-D calculated based on a given mineralogical composition. They therefore provide more reliable estimates compared to pure gravity models, which enhance modeling of the crustal structures. Our results clearly indicate presence of several lithospheric domains characterized by distinct features, Pannonian Basin being one of the most outstanding ones. It has the thinnest crust and lithosphere in the area modeled, characterized by relatively fertile composition.

  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

    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

    Second-to-fourth digit ratio is a widely investigated sexually dimorphic morphological trait in human studies and could reliably indicate the prenatal steroid environment. Conducting manipulative experiments to test this hypothesis comes up against ethical limits in humans. However, oviparous tetrapods may be excellent models to experimentally investigate the effects of prenatal steroids on offspring second-to-fourth digit ratio. In this field study, we injected collared flycatcher ( Ficedula albicollis) eggs with physiological doses of testosterone. Fledglings from eggs with elevated yolk testosterone, regardless of their sex, had longer second digits on their left feet than controls, while the fourth digit did not differ between groups. Therefore, second-to-fourth digit ratio was higher in the testosterone-injected group, but only on the left foot. This is the first study which shows experimentally that early testosterone exposure can affect second-to-fourth digit ratio in a wild population of a passerine bird.

    2013-04-01

    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.

  1. Hexabromocyclododecane in terrestrial passerine birds from e-waste, urban and rural locations in the Pearl River Delta, South China: Levels, biomagnification, diastereoisomer- and enantiomer-specific accumulation

    International Nuclear Information System (INIS)

    Diastereoisomers and enantiomers of hexabromocyclododecane (HBCD) were determined in muscle and stomach contents of three terrestrial passerine birds from e-waste, urban and rural locations in South China. The highest HBCD concentration was found at the urban site, followed by the e-waste site, suggesting that HBCD was linked to urbanization and industrialization, as well as e-waste recycling activities. Trophic magnification for α-HBCD was observed in the terrestrial food chain. Diastereisomeric pattern in birds showed the predominance of α-isomer, with a minor contribution of γ-isomer. The enantiomeric analysis revealed a preferential enrichment of (−)-α-HBCD and (+)-γ-HBCD. The similarity in enantiomeric fractions of HBCD isomers between muscle and stomach contents of birds suggested that dietary uptake may be responsible for the observed nonracemic distribution of HBCD isomers in the studied birds although in vivo enantioselective biotic processes cannot be ruled out. - Highlights: ► HBCD concentrations in three terrestrial passerine birds and their stomach contents were determined. ► Biomagnification and trophic magnification for α-HBCD was found. ► A preferential enrichment of (−)-α-HBCD and (+)-γ-HBCD were found in birds. ► Diet rather than in vivo biotic processes contributed to the observed nonracemic distribution of HBCD isomers. - Enantiomer-specific accumulation of hexabromocyclododecane in terrestrial passerine birds in South China was demonstrated.

  2. Contaminants of legacy and emerging concern in terrestrial passerines from a nature reserve in South China: Residue levels and inter-species differences in the accumulation

    International Nuclear Information System (INIS)

    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

    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.

  11. MDM2 gene SNP309 T/G and p53 gene SNP72 G/C do not influence diffuse large B-cell non-Hodgkin lymphoma onset or survival in central European Caucasians

    International Nuclear Information System (INIS)

    SNP309 T/G (rs2279744) causes higher levels of MDM2, the most important negative regulator of the p53 tumor suppressor. SNP72 G/C (rs1042522) gives rise to a p53 protein with a greatly reduced capacity to induce apoptosis. Both polymorphisms have been implicated in cancer. The SNP309 G-allele has recently been reported to accelerate diffuse large B-cell lymphoma (DLBCL) formation in pre-menopausal women and suggested to constitute a genetic basis for estrogen affecting human tumorigenesis. Here we asked whether SNP309 and SNP72 are associated with DLBCL in women and are correlated with age of onset, diagnosis, or patient's survival. SNP309 and SNP72 were PCR-genotyped in a case-control study that included 512 controls and 311 patients diagnosed with aggressive NHL. Of these, 205 were diagnosed with DLBCL. The age of onset was similar in men and women. The control and patients group showed similar SNP309 and SNP72 genotype frequencies. Importantly and in contrast to the previous findings, similar genotype frequencies were observed in female patients diagnosed by 51 years of age and those diagnosed later. Specifically, 3/20 female DLBCL patients diagnosed by 51 years of age were homozygous for SNP309 G and 2/20 DLBCL females in that age group were homozygous for SNP72 C. Neither SNP309 nor SNP72 had a significant influence on event-free and overall survival in multivariate analyses. In contrast to the previous study on Ashkenazi Jewish Caucasians, DLBCL in pre-menopausal women of central European Caucasian ethnicity was not associated with SNP309 G. Neither SNP309 nor SNP72 seem to be correlated with age of onset, diagnosis, or survival of patients

    1987-01-01

    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.

    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.

    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.

    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.

    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

    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.

  4. 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.

    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.

  6. Earlier breeding, lower success: does the spatial scale of climatic conditions matter in a migratory passerine bird?

    Following over 20 years of research on the climatic effects on biodiversity we now have strong evidence that climate change affects phenology, fitness, and distribution ranges of different taxa, including birds. Bird phenology likely responds to changes in local weather. It is also affected by climatic year-to-year variations on larger scales. Although such scale-related effects are common in ecology, most studies analyzing the effects of climate change were accomplished using climatic information on a single spatial scale. In this study, we aimed at determining the scale-dependent sensitivity of breeding phenology and success to climate change in a migratory passerine bird, the barn swallow (Hirundo rustica). For both annual broods, we investigated effects of local weather (local scale) and the North Atlantic Oscillation (NAO, large scale) on the timing of breeding and breeding success. Consistent with previous studies in migratory birds we found that barn swallows in Eastern Germany bred progressively earlier. At the same time, they showed reduced breeding success over time in response to recent climatic changes. Responses to climatic variation were observed on both local and large climatic scales, but they differed with respect to the ecological process considered. Specifically, we found that the timing of breeding was primarily influenced by large-scale NAO variations and to a lesser extent by local weather on the breeding grounds. Conversely, climatic conditions on the local scale affected breeding success, exclusively. The observed decrease in breeding success over years is likely a consequence of scale-related mismatches between climatic conditions during different breeding phases. This provides further evidence that a species' response of earlier breeding may not be enough to cope with climate change. Our results emphasize the importance of considering the response of ecological processes along different climatic scales in order to better understand the

  10. Organohalogen contamination in passerine birds from three metropolises in China: Geographical variation and its implication for anthropogenic effects on urban environments

    International Nuclear Information System (INIS)

    Contamination of organohalogen pollutants (OHPs), including dichlorodiphenyl trichloroethane and its metabolites (DDTs), polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), decabromodiphenylethane (DBDPE), hexabromocyclododecanes (HBCDs), and dechlorane plus (DP) in three metropolises of China, Beijing, Wuhan, and Guangzhou, and a reference rural site were determined using terrestrial residential passerine species as bioindicator. DDTs dominated in Wuhan whereas flame retardants dominated in Guangzhou and Beijing. No geographical variation was found for PCB levels but it exhibited different homologue profiles among different sites which could be attributed to different dietary sources of birds. Industry characteristics of the sampling location contributed to the geographical differences in the occurrence and contamination profile of OHPs. The transformation of traditional agriculture characterized contamination profiles to industry characterized profiles in Beijing and Guangzhou implicates significantly environmental concern on the flame retardants contamination in non-hot-spot regions of China. - Highlights: • Various OHPs were determined in passerine birds from three metropolises of China. • Geographical variations of OHPs levels and contamination profiles were observed. • More concern should be taken on the dominance of FRs in Chinese developed cities. • Diet source characterized by δ13C plays a key role in PCB pattern determination. - Geographical variations of OHPs contamination profiles indicate significant impact of industrialization and urbanization on Chinese urban environment

    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.

    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.

  17. 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

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.

    The major histocompatibility complex (MHC) genes are the most polymorphic genes found in the vertebrate genome, and they encode proteins that play an essential role in the adaptive immune response. Many songbirds (passerines) have been shown to have a large number of transcribed MHC class I genes...... compared to most mammals. To elucidate the reason for this large number of genes, we compared 14 MHC class I alleles (α1–α3 domains), from great reed warbler, house sparrow and tree sparrow, via phylogenetic analysis, homology modelling and in silico peptide-binding predictions to investigate their...... functional significance. The MHC class I allomorphs from house sparrow and tree sparrow, species that diverged 10 million years ago (MYA), had overlapping peptide-binding specificities, and these similarities across species were also confirmed in phylogenetic analyses based on amino acid sequences. Notably...

    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.
