    The importance of ticks and tick-borne pathogens for human and animal health has been increasing over the past decades. For their transportation and dissemination, birds may play a more important role than wingless hosts. In this study, tick infestation of birds in Germany was examined. Eight hundred ninety-two captured birds were infested with ticks and belonged to 48 different species, of which blackbirds (Turdus merula) and song thrushes (Turdus philomelos) were most strongly infested. Ground feeders were more strongly infested than non-ground feeders, sedentary birds more strongly than migratory birds, and short-distance migratory birds more strongly than long-distance migratory birds. Mean tick infestation per bird ranged between 2 (long-distance migratory bird) and 4.7 (sedentary bird), in some single cases up to 55 ticks per bird were found. With the exception of three nymphs of Haemaphysalis spp., all ticks belonged to Ixodes spp., the most frequently detected tick species was Ixodes ricinus. Birds were mostly infested by nymphs (65.1 %), followed by larvae (32.96 %). Additionally, ticks collected from birds were examined for several pathogens: Tick-borne encephalitis virus (TBEV) and Sindbisvirus with real-time RT-PCR, Flaviviruses, Simbuviruses and Lyssaviruses with broad-range standard RT-PCR-assays, and Borrelia spp. with a Pan-Borrelia real-time PCR. Interestingly, no viral pathogens could be detected, but Borrelia spp. positive ticks were collected from 76 birds. Borrelia (B.) garinii, B. valaisiaina, B. burgdorferi s.s. and B. afzelii were determined. The screening of ticks and birds for viral pathogens with broad range PCR-assays was tested and the use as an "early warning system" is discussed. PMID:27048511

  2. Nesting bird deterrents for the Federal Republic of Germany glass log storage pad

    International Nuclear Information System (INIS)

    A proposed storage pad wi11 be constructed in the 200 West Area for the storage of isotopic heat and radiation sources from the Federal Republic of Germany. The pad will be constructed in the southern portion of the Solid Waste Operations Complex near the existing Sodium Storage Pad (Figure 1). Following a biological review by Pacific Northwest National Laboratory (PNNL) personnel (Brandt 1996), it was determined that in order for construction to take place after March 15, 1997, actions would need to be taken to prevent migratory birds from nesting in the project area. Special attention was focused on preventing sage sparrows and loggerhead shrikes, both Hanford Site species of concern (DOE/RL 1996), from nesting in the area. This activity plan details the methods and procedures that will be used to implement these nesting deterrents

  4. Comparable high rates of extended-spectrum-beta-lactamase-producing Escherichia coli in birds of prey from Germany and Mongolia.

    Directory of Open Access Journals (Sweden)

    Sebastian Guenther

    Full Text Available Frequent contact with human waste and liquid manure from intensive livestock breeding, and the increased loads of antibiotic-resistant bacteria that result, are believed to be responsible for the high carriage rates of ESBL-producing E. coli found in birds of prey (raptors in Central Europe. To test this hypothesis against the influence of avian migration, we initiated a comparative analysis of faecal samples from wild birds found in Saxony-Anhalt in Germany and the Gobi-Desert in Mongolia, regions of dissimilar human and livestock population characteristics and agricultural practices. We sampled a total of 281 wild birds, mostly raptors with primarily north-to-south migration routes. We determined antimicrobial resistance, focusing on ESBL production, and unravelled the phylogenetic and clonal relatedness of identified ESBL-producing E. coli isolates using multi-locus sequence typing (MLST and macrorestriction analyses. Surprisingly, the overall carriage rates (approximately 5% and the proportion of ESBL-producers among E. coli (Germany: 13.8%, Mongolia: 10.8% were similar in both regions. Whereas bla(CTX-M-1 predominated among German isolates (100%, bla(CTX-M-9 was the most prevalent in Mongolian isolates (75%. We identified sequence types (STs that are well known in human and veterinary clinical ESBL-producing E. coli (ST12, ST117, ST167, ST648 and observed clonal relatedness between a Mongolian avian ESBL-E. coli (ST167 and a clinical isolate of the same ST that originated in a hospitalised patient in Europe. Our data suggest the influence of avian migratory species in the transmission of ESBL-producing E. coli and challenge the prevailing assumption that reducing human influence alone invariably leads to lower rates of antimicrobial resistance.

  8. X-ray investigations of lead shot pellets in the tissues of various species of birds found dead in Northern Germany

    International Nuclear Information System (INIS)

    Within the period 1985-1988 467 specimens of dead or moribund birds including 51 species were collected in northern Germany, and x-rayed to ascertain lead pellet damage. In 15.8% of the cases evidence of lead bullets was found in the tissues. In over 80% of the cases lead pellets were found, and in 11 (14.9%) of the animals air rifle ammunition was discovered. Along with wood cock, greylag geese, and eider ducks several species of sea gulls were especially affected. The exact causes of death of the lead damaged birds could usually not be determined. The problems with lead pellet ammunition are presented and a legally designated maximum shooting distance is recommended. The replacement of lead pellets with small caliber ammunition for hunting from blinds is also discussed. Bullets are considered more effective for the hunting of knob-billed swans

    further surprises. The 'head' and major parts of the 'Bird' are moving apart at more than 400 km/s (1.4 million km/h!). Observing such high velocities is very rare in merging galaxies. Also, the 'head' appears to be the major source of infrared luminosity in the system, though it is the smallest of the three galaxies. "It seems that NACO has caught the action right at the time of the first high-speed fly-by of the 'head' galaxy through the system consisting of the other two galaxies," says Seppo Mattila, member of the discovery team. "These two galaxies must have met earlier, probably a couple of hundred million years ago." The 'head' is forming stars violently, at a rate of nearly 200 solar masses per year, while the other two galaxies appear to be at a more quiescent epoch of their interaction-induced star formation history. The 'Bird' belongs to the prestigious family of luminous infrared galaxies, with an infrared luminosity nearly one thousand billion times that of the Sun. This family of galaxies has long been thought to signpost important events in galaxy evolution, such as mergers of galaxies, which in turn trigger bursts of star formation, and may eventually lead to the formation of a single elliptical galaxy. The findings presented here are reported in a paper to appear in a future issue of the journal Monthly Notices of the Royal Astronomical Society ("Adaptive optics imaging and optical spectroscopy of a multiple merger in a luminous infrared galaxy", by P. Väisänen" et al.). Note [1]: The team is composed of P. Väisänen, A. Kniazev, D. A. H. Buckley, L. Crause, Y. Hashimoto, N. Loaring, E. Romero-Colmenero, and M. Still (SAAO, South Africa), S.

    1. Most biodiversity is still unknown, and therefore, priority areas for conservation typically are identified based on the presence of surrogates, or indicator groups. Birds are commonly used as surrogates of biodiversity owing to the wide availability of relevant data and their broad popular...... appeal. However, some studies have found birds to perform relatively poorly as indicators. We therefore ask how the effectiveness of this approach can be improved by supplementing data on birds with information on other taxa. 2. Here, we explore two strategies using (i) species data for other taxa...... areas identified on the basis of birds alone performed well in representing overall species diversity where birds were relatively speciose compared to the other taxa in the data sets. Adding species data for one taxon increased surrogate effectiveness better than adding genus- and family-level data...

  2. Christmas Island birds returning

    Science.gov (United States)

    Six months after their mass exodus, birds are beginning to return to Christmas Island. Roughly 17 million birds, almost the entire adult bird population, either perished or fled their mid-Pacific atoll home last autumn, leaving behind thousands of nestlings to starve (Eos, April 5, 1983, p. 131). It is believed that the strong El Niño altered the ecology of the surrounding waters and forced the birds to flee. Christmas Island is the world's largest coral atoll.“Ocean and atmosphere scientists are unsure of future directions for the El Niño conditions and cannot now predict what will happen to the birds in the coming months,” said Ralph W. Schreiber, curator of ornithology at the Natural History Museum of Los Angeles County in California.

    Recent studies have documented the growth of earnings inequality in the United States during the 1980s. In contrast to these studies' findings, our analysis of micro data for the former West Germany yields virtually no evidence of growth in earnings inequality over the same period. Between 1978 and 1988, a reduction in the dispersion of earnings among workers in the bottom half of the earnings distribution led to a narrowing of the overall dispersion of earnings in Germany. Earnings different...

  7. Germany; an Immigration Country

    Germany has about the same proportion of foreigners in its population as the United States, it is an immigration country. In a way, Germany has let immigration happen, but it did not really have an explicit immigration policy in the past. Now it has to make up its mind on its immigration policy in the future. The paper looks at the experience with immigration in the past, at the integration of foreigners and at the issues of immigration policy.

    Full Text Available We examined bird diversity in relation to land use and socioeconomic indicators in Leipzig, Germany. We used neighborhood diversity (ND and bivariate correlation to show that the potential to experience biodiversity in a city is associated with population density, household income, unemployment, and urban green space. People living in urban districts with high socioeconomic status experience the highest species richness around their homes, whereas lower social status increases the chance of living in species-poor neighborhoods. High-status districts are located along forests, parks, and rivers that have a high quantity and quality of green space. However, green space in general does not guarantee high bird diversity. We conclude that bird diversity mirrors land use and socioeconomic patterns within the compact European city of Leipzig. Therefore, urban planning should focus on decreasing these patterns and protecting the remaining species-rich green spaces.

    Birds utilize several distinct sensory systems in a flexible manner in their navigation. When navigating with the help of landmarks, location of the sun and stars, or polarization image of the dome of the sky, they resort to vision. The significance of olfaction in long-range navigation has been under debate, even though its significance in local orientation is well documented. The hearing in birds extends to the infrasound region. It has been assumed that they are able to hear the infrasounds generated in the mountains and seaside and navigate by using them. Of the senses of birds, the most exotic one is the ability to sense magnetic fields of the earth. PMID:27522832

  1. Biomechanics of bird flight.

    Science.gov (United States)

    Tobalske, Bret W

    2007-09-01

    Power output is a unifying theme for bird flight and considerable progress has been accomplished recently in measuring muscular, metabolic and aerodynamic power in birds. The primary flight muscles of birds, the pectoralis and supracoracoideus, are designed for work and power output, with large stress (force per unit cross-sectional area) and strain (relative length change) per contraction. U-shaped curves describe how mechanical power output varies with flight speed, but the specific shapes and characteristic speeds of these curves differ according to morphology and flight style. New measures of induced, profile and parasite power should help to update existing mathematical models of flight. In turn, these improved models may serve to test behavioral and ecological processes. Unlike terrestrial locomotion that is generally characterized by discrete gaits, changes in wing kinematics and aerodynamics across flight speeds are gradual. Take-off flight performance scales with body size, but fully revealing the mechanisms responsible for this pattern awaits new study. Intermittent flight appears to reduce the power cost for flight, as some species flap-glide at slow speeds and flap-bound at fast speeds. It is vital to test the metabolic costs of intermittent flight to understand why some birds use intermittent bounds during slow flight. Maneuvering and stability are critical for flying birds, and design for maneuvering may impinge upon other aspects of flight performance. The tail contributes to lift and drag; it is also integral to maneuvering and stability. Recent studies have revealed that maneuvers are typically initiated during downstroke and involve bilateral asymmetry of force production in the pectoralis. Future study of maneuvering and stability should measure inertial and aerodynamic forces. It is critical for continued progress into the biomechanics of bird flight that experimental designs are developed in an ecological and evolutionary context. PMID:17766290

    Full Text Available Abstract Background Systematic pathological investigations to assess the health status of seabirds and coastal birds in Germany were performed. The investigation was conducted to obtain data on possible causes of decline in seabird and coastal bird populations. Methods 48 individuals of 11 different species of seabirds and coastal birds were collected by the stranding network along the entire German North Sea coast from 1997 to 2008, including mainly waders such as Eurasian oystercatchers (Haematopus ostralegus and red knots (Calidris canutus as well as seabirds such as northern fulmars (Fulmaris glacialis and common scoters (Melanitta nigra. For most birds (n = 31 found dead along the shore no obvious cause of death was evident, while 17 individuals were killed by collisions with lighthouses. Results Overall, the nutritional status of the investigated birds was very poor, and the body mass in most cases was significantly lower compared to masses of living birds caught during the same periods of the year. This is partly linked to chronic parasitic or bacterial infections in different organs or to septicaemia. In some cases infections with zoonotic tuberculosis caused by Mycobacterium spp. were found. Avian influenza was not found in any of the collected birds. Conclusion The presented data contribute to the evaluation of the health status of birds in the German North Sea. Moreover, they present an important tool for the assessment of potential pathogens with an impact on the health status of seabirds and coastal birds.

    This paper describes the parasitologic findings for 60 synanthropic bird carcasses recovered in the Campania region of southern Italy. Birds consisted of 20 yellow-legged gulls (Larus michahellis), 15 rock pigeons (Columba livia), 15 common kestrels (Falco tinnunculus), and 10 carrion crows (Corvus corone). Each carcass was examined to detect the presence of ectoparasites and then necropsied to detect helminths. Ectoparasites occurred in 100% of the birds examined. In particular, chewing lice were recovered with a prevalence of 100%, whereas Pseudolynchia canariensis (Hippoboscidae) were found only in pigeons with a prevalence of 80%. Regarding endoparasites, a total of seven helminth species were identified: three nematodes (Ascaridia columbae, Capillaria columbae, Physaloptera alata), one cestoda (Raillietina tetragona), one trematoda (Cardiocephalus longicollis), and two acanthocephalans (Centrorhynchus globocaudatus and Centrorhynchus buteonis). The findings of the present study add data to the parasitologic scenario of synanthropic birds. This is important because parasitic infection can lead to serious health problems when combined with other factors and may affect flying performance and predatory effectiveness. PMID:24597118

  13. Birds and wind energy

    Energy Technology Data Exchange (ETDEWEB)

    Langston, Rowena

    2011-07-01

    Full text: Climate change, perhaps more accurately described as climate disruption, is considered to be a major long-term threat to biodiversity, with a high probability that the underlying cause is due to anthropogenic greenhouse gas emissions. Renewable energy is an important component of a programme of measures to combat further climate change, to include improved energy efficiency and demand management. Wind energy is the most advanced renewable energy source and is a global industry onshore and, increasingly, offshore. However, as with any form of energy generation, wind energy also has potential environmental costs which have to be balanced against benefits. The environmental impacts on birds derive from the following: collision risk, in particular from the moving rotor blades; displacement arising from disturbance during construction, operation or decommissioning; habitat loss or change leading to alteration of food availability; barrier effects leading to deviation of long distance migratory flights or disruption of local flights between feeding, nesting, and roosting/loafing locations. Not all species of birds, or individuals within a species, are equally susceptible to negative interactions with wind turbines, and neither are the population consequences of impacts equivalent. Of greatest concern are bird species of conservation concern that exhibit behaviours that place them at risk of an adverse impact, notably when that impact leads to a reduction in population size that is unlikely to be compensated for. In particular, cumulative impacts arising from multiple wind farms or wind farms in combination with other developments are of concern. There has been a welcome increase in research effort and peer-reviewed publications on the subject of birds and wind energy in recent years. Increasing our understanding of impacts is essential to delivering possible solutions and this paper reviews current knowledge for birds. (Author)

  2. Assessing the regional impacts of increased energy maize cultivation on farmland birds.

    Science.gov (United States)

    Brandt, Karoline; Glemnitz, Michael

    2014-02-01

    The increasing cultivation of energy crops in Germany substantially affects the habitat function of agricultural landscapes. Precise ex ante evaluations regarding the impacts of this cultivation on farmland bird populations are rare. The objective of this paper was to implement a methodology to assess the regional impacts of increasing energy maize cultivation on the habitat quality of agricultural lands for farmland birds. We selected five farmland bird indicator species with varying habitat demands. Using a crop suitability modelling approach, we analysed the availability of potential habitat areas according to different land use scenarios for a real landscape in Northeast Germany. The model was based on crop architecture, cultivation period, and landscape preconditions. Our results showed that the habitat suitability of different crops varied between bird species, and scenario calculations revealed an increase and a decrease in the size of the potential breeding and feeding habitats, respectively. The effects observed in scenario 1 (increased energy maize by 15%) were not reproduced in all cases in scenario 2 (increased energy maize by 30%). Spatial aggregation of energy maize resulted in a negative effect for some species. Changes in the composition of the farmland bird communities, the negative effects on farmland bird species limited in distribution and spread and the relevance of the type of agricultural land use being replaced by energy crops are also discussed. In conclusion, we suggest a trade-off between biodiversity and energy targets by identifying biodiversity-friendly energy cropping systems. PMID:24323319

  3. Nuclear power in Germany

    International Nuclear Information System (INIS)

    I want to give some ideas on the situation of public and utility acceptance of nuclear power in the Federal Republic of Germany and perhaps a little bit on Europe. Let me start with public perception. I think in Germany we have a general trend in the public perception of technology during the last decade that has been investigated in a systematic manner in a recent study. It is clear that the general acceptance of technology decreased substantially during the last twenty years. We can also observe during this time that aspects of the benefits of technology are much less reported in the media, that most reporting by the media now is related to the consequences of technologies, such as negative environmental consequences. hat development has led to a general opposition against new technological projects, in particular unusual and large. That trend is related not only to nuclear power, we see it also for new airports, trains, coal-fired plants. here is almost no new technological project in Germany where there is not very strong opposition against it, at least locally. What is the current public opinion concerning nuclear power? Nuclear power certainly received a big shock after Chernobyl, but actually, about two thirds of the German population wants to keep the operating plants running. Some people want to phase the plants out as they reach the end-of-life, some want to substitute newer nuclear technology, and a smaller part want to increase the use of nuclear power. But only a minority of the German public would really like to abandon nuclear energy

  4. Cardiac rehabilitation in Germany.

    2007-02-01

    The purpose of this review is to give an overview of the rehabilitation measures provided for cardiac patients in Germany and to outline its legal basis and outcomes. In Germany the cardiac rehabilitation system is different from rehabilitation measures in other European countries. Cardiac rehabilitation in Germany since 1885 is based on specific laws and the regulations of insurance providers. Cardiac rehabilitation has predominantly been offered as an inpatient service, but has recently been complemented by outpatient services. A general agreement on the different indications for offering these two services has yet to be reached. Cardiac rehabilitation is mainly offered after an acute cardiac event and bypass surgery. It is also indicated in severe heart failure and special cases of percutaneous coronary intervention. Most patients are men (>65%) and the age at which events occur is increasing. The benefits obtained during the 3-4 weeks after an acute event, and confirmed in numerous studies, are often later lost under 'usual care' conditions. Many attempts have been made by rehabilitation institutions to improve this deficit by providing intensive aftercare. One instrument set up to achieve this is the nationwide institution currently comprising more than 6000 heart groups with approximately 120000 outpatients. After coronary artery bypass grafting or acute coronary syndrome cardiac rehabilitation can usually be started within 10 days. The multidisciplinary rehabilitation team consists of cardiologists, psychologists, exercise therapists, social workers, nutritionists and nurses. The positive effects of cardiac rehabilitation are also important economically, for example, for the improvement of secondary prevention and vocational integration. PMID:17301623

  5. Liver transplantation in Germany.

    Science.gov (United States)

    Tacke, Frank; Kroy, Daniela C; Barreiros, Ana Paula; Neumann, Ulf P

    2016-08-01

    Liver transplantation (LT) is a well-accepted procedure for end-stage liver disease in Germany. In 2015, 1489 patients were admitted to the waiting list (including 1308 new admissions), with the leading etiologies being fibrosis and cirrhosis (n = 349), alcoholic liver disease (n = 302), and hepatobiliary malignancies (n = 220). Organ allocation in Germany is regulated within the Eurotransplant system based on urgency as expressed by the Model for End-Stage Liver Disease score. In 2015, only 894 LTs (n = 48 from living donors) were performed at 23 German transplant centers, reflecting a shortage of organs. Several factors may contribute to the low number of organ donations. The German transplant legislation only accepts donation after brain death (not cardiac death), whereas advances in neurosurgery and a more frequently requested "palliative care" approach render fewer patients suitable as potential donors. The legislation further requires the active consent of the donor or first-degree relatives before donation. Ongoing debates within the German transplant field address the optimal management of patients with alcoholic liver cirrhosis, hepatocellular carcinoma (HCC), and cholangiocarcinoma and measures to increase living donor transplantations. As a result of irregularities at mainly 4 German transplant centers that were exposed in 2012, guiding principles updated by the German authorities have since implemented strict rules (including internal and external auditing, the 8-eyes principle, mandatory repeated testing for alcohol consumption) to prohibit any manipulations in organ allocation. In conclusion, we will summarize important aspects on the management of LT in Germany, discuss legal and organizational aspects, and highlight challenges mainly related to the relative lack of organ donations, increasing numbers of extended criteria donors, and the peculiarities of the recipient patients.

  6. Germany, Pacifism and Peace Enforcement

    DEFF Research Database (Denmark)

    Dalgaard-Nielsen, Anja

    This book is about the transformation of Germany's security and defence policy in the time between the 1991 Gulf War and the 2003 war against Iraq. It traces and explains the reaction of Europe's biggest and potentially most powerful country to the ethnic wars of the 1990s, the emergence of large......-scale terrorism, and the new US emphasis on pre-emptive strikes. Based on an analysis of Germany's strategic culture, it portrays Germany as a security actor and indicates the conditions and limits of the new German willingness to participate in international military crisis management that developed over the...... 1990s. The book debates the implications of Germany's transformation for Germany's partners and neighbours, and explains why Germany said ‘yes’ to the war in Afghanistan, but ‘no’ to the Iraq War. Based on a comprehensive study of the debates of the German Bundestag and actual German policy responses...

    The basic principles for waste management in Germany are established in the Atomic Energy Act and in the waste management concept of the German Government which gives greater substance to the statutory requirements and the principles of the waste management provisions for nuclear power plants. The resolution passed on 28 September 1979 by the heads of the State and Federal Governments confirms the integral waste management concept; it is based in general on onsite and offsite interim storage followed by reprocessing of spent fuel, recovery of radioactive materials, and conditioning for the final disposal of radioactive waste

  11. The North Sea Bird Club

    International Nuclear Information System (INIS)

    This paper reports that the creation of a club for the purpose of encouraging oil and gas workers to watch birds may not at first seem a viable proposition. To the layperson, birds offshore conjures up an image of hundreds of seagulls following fishing boats, and very little else. Also, the act of birdwatching is not seen as a typical offshore worker's activity. Anyone who has worked on an installation offshore and who has any interest in wildlife will be aware of the occasional presence of land-birds. Two decades ago, prompted by some keen offshore workers, a single oil company set up a monitoring program, which quickly became popular with a number of its employees. Birds seem offshore were recorded on data forms and collected together. At this stage the club was purely another recreation facility; however, when the data were collated it was soon realized that installations offshore were being used as staging posts by birds on migration, and that the information being collected would be of great interest in the study of bird movements. All over Britain, at strategic points on the coastline, there are bird observatories which record the arrival and departure of migrating birds. The presence of several hundred solid structures up and down the North Sea, which are used by birds en route, represents a huge, unique bird observatory, capable of uncovering facts about bird migration which have long eluded land-based scientists. Eleven years ago, the North Sea Bird Club began, composed of eight member companies, a recorder from Aberdeen University and a representative from the Nature Conservancy Council. The club received data from 41 installations, and the recorder collated these on Aberdeen University's computer and produced an annual report of sightings

    Bartonella spp. infections are considered to be vector-borne zoonoses; ticks are suspected vectors of bartonellae. Migratory birds can disperse ticks infected with zoonotic pathogens such as Rickettsia and tickborne encephalitis virus and possibly also Bartonella. Thus, in the present study 386 tick specimens collected in spring 2009 from migratory birds on the Mediterranean islands Capri and Antikythera were screened for Bartonella spp. RNA. One or more ticks were found on 2.7% of the birds....

    2010-08-01

    A bird species is regarded as alien invasive if it has been introduced, intentionally or accidentally, to a location where it did not previously occur naturally, becomes capable of establishing a breeding population without further intervention by humans, spreads and becomes a pest affecting the environment, the local biodiversity, the economy and/or society, including human health. European Starling (Sturnus vulgaris), Common Myna (Acridotheres tristis) and Red-vented Bulbul (Pycnonotus cafer) have been included on the list of '100 of the World's Worst Invasive Alien Species', a subset of the Global Invasive Species Database. The 'Delivering Alien Invasive Species Inventories for Europe' project has selected Canada Goose (Branta canadensis), Ruddy Duck (Oxyura jamaicensis), Rose-ringed Parakeet (Psittacula krameri) and Sacred Ibis (Threskiornis aethiopicus) as among 100 of the worst invasive species in Europe. For each of these alien bird species, the geographic range (native and introduced range), the introduction pathway, the general impacts and the management methods are presented. PMID:20919578

    The basis of the licensing approach in Germany is the Act on the peaceful use of nuclear energy and the protection against its hazards (Atomic Energy Act) with subordinated rules guidelines and standards. Due to the federal structure of Germany, the state authorities are responsible for the licensing of nuclear power plants. First applications of computer based Instrumentation and Control were introduced in the frame of minor upgrading projects, the associated assessment and licensing activities were performed on a case by case basis, with existing rules and guidelines (e.g. issued by KTA or the German Reactor Safety Commission - RSK) applied according to the safety rationale laid down in these documents. Since specific national standards and guidelines for digital Instrumentation and Control were not available, international standards, especially IEC 60880, have been used in addition. The structure consists of four protection goals and five auxiliary functions embracing these goals. The protection goals and the principle tasks to be performed in order to meet these goals are (definition according to the Federal Office for Radiation Protection BfS). This covers the following: Control of Reactivity, cooling of Fuel Elements, Enclosure of Radioactive Substances, Limitation of Radiation Exposure, Auxiliary functions embracing the protection goals referring to the reliability, entire plant, administration, instrumentation and control, power supplies. Depending on the safety importance of the functions and the associated reliability requirements, the I and C architecture (e.g. the degree of redundancy) is developed and appropriate equipment is selected to build up the I and C system. As mentioned above a clear requirement specification is an important pre-requisite for defining the process and the related I and C functions. Moreover it provides the basis for grading the requirements for a classification system. According to the RSK Guidelines following basic

    Busse, Reinhard; Blümel, Miriam

    2014-01-01

    This analysis of the German health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. In the German health care system, decision-making powers are traditionally shared between national (federal) and state (Land) levels, with much power delegated to self-governing bodies. It provides universal coverage for a wide range of benefits. Since 2009, health insurance has been mandatory for all citizens and permanent residents, through either statutory or private health insurance. A total of 70 million people or 85% of the population are covered by statutory health insurance in one of 132 sickness funds in early 2014. Another 11% are covered by substitutive private health insurance. Characteristics of the system are free choice of providers and unrestricted access to all care levels. A key feature of the health care delivery system in Germany is the clear institutional separation between public health services, ambulatory care and hospital (inpatient) care. This has increasingly been perceived as a barrier to change and so provisions for integrated care are being introduced with the aim of improving cooperation between ambulatory physicians and hospitals. Germany invests a substantial amount of its resources on health care: 11.4% of gross domestic product in 2012, which is one of the highest levels in the European Union. In international terms, the German health care system has a generous benefit basket, one of the highest levels of capacity as well as relatively low cost-sharing. However, the German health care system still needs improvement in some areas, such as the quality of care. In addition, the division into statutory and private health insurance remains one of the largest challenges for the German health care system, as it leads to inequalities. PMID:25115137

    Abstract Background  Infections of wild birds with highly pathogenic avian influenza (AI) subtype H5N1 virus were reported for the first time in the European Union in 2006. Objectives  To capture epidemiological information on H5N1 HPAI in wild bird populations through large‐scale surveillance and extensive data collection. Methods  Records were analysed at bird level to explore the epidemiology of AI with regard to species of wild birds involved, timing and location of infections as well as the applicability of different surveillance types for the detection of infections. Results  In total, 120,706 records of birds were sent to the Community Reference Laboratory for analysis. Incidents of H5N1 HPAI in wild birds were detected in 14 EU Member States during 2006. All of these incidents occurred between February and May, with the exception of two single cases during the summer months in Germany and Spain. Conclusions  For the detection of H5N1 HPAI virus, passive surveillance of dead or diseased birds appeared the most effective approach, whilst active surveillance offered better detection of low pathogenic avian influenza (LPAI) viruses. No carrier species for H5N1 HPAI virus could be identified and almost all birds infected with H5N1 HPAI virus were either dead or showed clinical signs. A very large number of Mallards (Anas platyrhynchos) were tested in 2006 and while a high proportion of LPAI infections were found in this species, H5N1 HPAI virus was rarely identified in these birds. Orders of species that appeared to be very clinically susceptible to H5N1 HPAI virus were swans, diving ducks, mergansers and grebes, supporting experimental evidence. Surveillance results indicate that H5N1 HPAI virus did not establish itself successfully in the EU wild bird population in 2006. PMID:19453436

    An important implementation issue for wind farms is the risk of bird collision. Much of the existing knowledge on birds and wind energy is based on studies of onshore sites. With respect to wind energy implementation especially offshore, more information about the environmental impact is needed. Several countries carrying out environmental base line studies focused on offshore wind farm sites. Monitoring wildlife is very labour intensive. Therefore, ECN develops a computer based efficient environmental monitoring tool. The aim is to develop, demonstrate and evaluate a noise monitoring system, which identifies bird impacts and also indicates the species. The system must be relatively inexpensive, robust and applicable for offshore conditions. The system identifies bird impacts by noise measurements and a camera identifies the specific species. The system can also distinguish between turbine specific sounds and a real collision against tower, nacelle and rotor. The WT-Bird detection system built by ECN appears to be a very promising way to detect bird collisions against wind turbines. The first experimental results are good. This way of detecting the collisions of birds can be very useful for the future implementation of offshore wind farms.

  3. Wind energy in Germany

    International Nuclear Information System (INIS)

    End of June 1994 429 MW in about 2100 wind energy converters (WECs) have been installed in Germany, able to produce 1.1% of the electrical energy demand of the five German coastal states Lower Saxony, Bremen, Hamburg, Schleswig-Holstein and Mecklenburg-Vorpommern. Determining factor for the again increased installation rate, compared with 1993, is the new 500/600-kW-class which now dominates the market. Dramatically reduced WEC prices during the last two years now allow an economic operation in good wind speed regions even without any subsidy. The goal to reach a total of 2000 MW WEC installations in the year 2000 is suddenly near at hand. In the course of the next seven years an installation rate of 250 MW/year will be necessary, a value which could be reached already in 1994. Nevertheless, there still is a long way to go, if the 2000 MW shall be achieved in the year 2000. New obstacles have arisen due to the increasingly restrictive handling of WEC site permission by conservationists, often in discrepancy with the generally recognized global ideas of the eco-organizations. After more than two years of experience, the WEC quality dependent subsidy as applied in Lower Saxony proofs to be a very effective stimulation for the technical development. WECs are now optimized for maximum energy production and minimum noise emission. The new 500/600-kW class is only half as noisy as could be expected from an extrapolation based on smaller WEC units. The energy cost reduction with the size of the WECs is still going on, indicating that the new Megawatt-WECs in development can offer again an economic advantage for the operator. (orig.)

    International Nuclear Information System (INIS)

    Germany, there are 19 operating nuclear power plants, with a total installed capacity of 21.4 GWe. In 2002, the electricity production of these 19 nuclear power plants amounted to 165 TWh, i.e. 1/3 of the total electricity production. The average availability of the German nuclear power plants was 85.6 % (this low value is due to the unexpected outage of some NPPs). The expressed goal of the German Federal Government is to phase out of nuclear energy without paying compensations to the utilities. On 11 June 2001, the final agreement between the German utilities and the German Federal Government was signed, and the amendment to the German Atomic Law (AtG-Novelle) was enforced on 27 April 2002. The overall objective of the new AtG is changed from 'support of nuclear energy' to 'fix phase-out of nuclear energy'. After the German parliament elections, the new Government coalition formulated a Coalition Contract which has the following statements on Nuclear Energy: - Work out an energy research programme which gives first priority to renewable energies and energy efficiency, - Assess termination of EURATOM membership, - Terminate nuclear electricity production on the base of a guaranteed total amount of electricity produced (in GWh),No reprocessing after 2005, - Erection of interim storages at nuclear power plant sites, - Support of research to improve safety of existing reactors, - Stop of national support for development of techniques for nuclear energy production (this includes fission and fusion). The German Committee on a Selection Procedure for Repository Sites (AkEnd) was established 1998 by the Ministry of Environment, Nature Conservation and Nuclear Safety (BMU) reached agreement on the following main issues: - One final repository concept, - Storage in deep geological formation starting about 2030, - Isolation for 1 million years, - Under-ground exploration of at lease two sites, - One selection criteria for the final repository is the transparency of

  5. Structural Colors of Birds

    Structural colors create iridescent colors in bird feathers. The goal is to understand why structural colors act the way they do in certain situations. The research conducted over the course of the fall semester was to understand the optical phenomenon producing colors in individual barbules. Through the use of a polarizing optical microscope, certain hypotheses were built to explain certain phenomenon. Using a dark field illumination involving light acting at wide angles in microscopy, the barbules were not affected by polarization. So it can be suggested that the barbules have certain characteristics, possibly internal, which prevents wide-angle polarization. More recently, it was found that the barbules, when stacked upon one another, create a discoloration at the cross over point. It can be suggested that the barbules act as thin films and create a situation of thin film interference. More data will be taken using the Scanning Electron Microscope as well as getting cross sectional data to help understand the internal characteristics of the barbules.

    In 2008, avian bornaviruses (ABV) were identified as the cause of proventricular dilatation disease (PDD). PDD is a significant condition of captive parrots first identified in the late 1970s. ABV infection has subsequently been shown to be widespread in wild waterfowl across the United States and Canada where the virus infects 10-20% of some populations of ducks, geese and swans. In most cases birds appear to be healthy and unaffected by the presence of the virus; however, infection can also result in severe non-suppurative encephalitis and lesions similar to those seen in parrots with PDD. ABVs are genetically diverse with seven identified genotypes in parrots and one in canaries. A unique goose genotype (ABV-CG) predominates in waterfowl in Canada and the northern United States. ABV appears to be endemic in North American waterfowl, in comparison to what appears to be an emerging disease in parrots. It is not known whether ABV can spread between waterfowl and parrots. The discovery of ABV infection in North American waterfowl suggests that European waterfowl should be evaluated for the presence of ABV, and also as a possible reservoir species for Borna disease virus (BDV), a related neurotropic virus affecting horses and sheep in central Europe. Although investigations have suggested that BDV is likely derived from a wildlife reservoir, for which the shrew and water vole are currently prime candidates, we suggest that the existence of other mammalian and avian reservoirs should not be discounted.

    Full Text Available In 2005, the Swiss official feed inspection of Agroscope Liebefeld-Posieux Research Station (ALP was mandated to check bird feed and raw materials for the presence of Ambrosia sp. seeds. Indeed, such seeds were found in varying amounts when analyzed in the feed microscopy laboratory. The producers were informed, and a limit of intervention (50 mg.kg-1 ≈ 9 to 10 seeds.kg-1 was finally set for this undesirable component. The results of five years of controls show, at first, around 50% of contaminated samples. With appropriate measures, the level of contamination could be lowered in the following years. In parallel, the size of Ambrosia sp. seeds and the sieves to be used for routine analyses were checked. Ambrosia sp. seeds found in feed checked in Switzerland were seldom larger ("wider" than 3.5 mm and never smaller than 1.5 mm. Several EU Member States started their own control and monitoring programs. The results of studies from Germany, Slovenia and Denmark, presented by their feed microscopists at the IAG meetings, indicate the presence of Ambrosia sp. seeds in 21 to 75% of the products put on the market.

    1978-10-01

    The work accomplished during the period covered in this technical progress report demonstrates the importance, interest, and necessity of a distribution study of marine birds in the Georges Bank area on a national and international scale. Cooperation was extended by the U.S. National Marine Fisheries Service, U.S. Fish and Wildlife Service, U.S. Coast Guard, and by the Canadian Wildlife Service, Halifax, N.S., AltantNIRO, Kaliningrad, USSR, and Federal Republic of Germany. Two sampling methods, fixed-area and total bird counts, were effectively employed, which allow comparable data bases with marine bird distribution information being collected in the North Pacific, Bering and Chukchi Seas (Outer Continental Shelf Energy Assessment Program), and in the North Atlantic and Canadian Arctic (CWS and The Seabird Group). A marine bird data retrieval bank is being developed for MBO seabird data at the USFWS Migratory Bird and Habitat Research Laboratory. A food habits bibliography and prey item/bird species summary table for marine birds in the western North Atlantic has been prepared from existing literature. Unpublished NMFS data on zooplankton/ichthyoplankton, and ground fish is being made available for possible correlations in distribution of selected prey items with bird species.

    Full Text Available Scientific background: The annual number of joint replacement operations in Germany is high. The introduction of an arthroplasty register promises an important contribution to the improvement of the quality of patient’s care. Research questions: The presented report addresses the questions on organization and functioning, benefits and cost-benefits as well as on legal, ethical and social aspects of the arthroplasty registers. Methods: A systematic literature search was conducted in September 2008 in the medical databases MEDLINE, EMBASE etc. and was complemented with a hand search. Documents describing arthroplasty registers and/or their relevance as well as papers on legal, ethical and social aspects of such registers were included in the evaluation. The most important information was extracted and analysed. Results: Data concerning 30 arthroplasty registers in 19 countries as well as one international arthroplasty register were identified. Most of the arthroplasty registers are maintained by national orthopedic societies, others by health authorities or by their cooperation. Mostly, registries are financially supported by governments and rarely by other sources.The participation of the orthopedists in the data collection process of the arthroplasty registry is voluntary in most countries. The consent of the patients is usually required. The unique patient identification is ensured in nearly all registers.Each data set consists of patient and clinic identification numbers, data on diagnosis, the performed intervention, the operation date and implanted prostheses. The use of clinical scores, patient-reported questionnaires and radiological documentation is rare. Methods for data documentation and transfer are paper form, electronic entry as well as scanning of the data using bar codes. The data are mostly being checked for their completeness and validity. Most registers offer results of the data evaluation to the treating orthopedists and

  17. Lab-on-a-bird: biophysical monitoring of flying birds.

    Directory of Open Access Journals (Sweden)

    Abdurrahman Gumus

    Full Text Available The metabolism of birds is finely tuned to their activities and environments, and thus research on avian systems can play an important role in understanding organismal responses to environmental changes. At present, however, the physiological monitoring of bird metabolism is limited by the inability to take real-time measurements of key metabolites during flight. In this study, we present an implantable biosensor system that can be used for continuous monitoring of uric acid levels of birds during various activities including flight. The system consists of a needle-type enzymatic biosensor for the amperometric detection of uric acid in interstitial fluids. A lightweight two-electrode potentiostat system drives the biosensor, reads the corresponding output current and wirelessly transfers the data or records to flash memory. We show how the device can be used to monitor, in real time, the effects of short-term flight and rest cycles on the uric acid levels of pigeons. In addition, we demonstrate that our device has the ability to measure uric acid level increase in homing pigeons while they fly freely. Successful application of the sensor in migratory birds could open up a new way of studying birds in flight which would lead to a better understanding of the ecology and biology of avian movements.

  6. Do birds sleep in flight?

    Science.gov (United States)

    Rattenborg, Niels C.

    2006-09-01

    The following review examines the evidence for sleep in flying birds. The daily need to sleep in most animals has led to the common belief that birds, such as the common swift ( Apus apus), which spend the night on the wing, sleep in flight. The electroencephalogram (EEG) recordings required to detect sleep in flight have not been performed, however, rendering the evidence for sleep in flight circumstantial. The neurophysiology of sleep and flight suggests that some types of sleep might be compatible with flight. As in mammals, birds exhibit two types of sleep, slow-wave sleep (SWS) and rapid eye-movement (REM) sleep. Whereas, SWS can occur in one or both brain hemispheres at a time, REM sleep only occurs bihemispherically. During unihemispheric SWS, the eye connected to the awake hemisphere remains open, a state that may allow birds to visually navigate during sleep in flight. Bihemispheric SWS may also be possible during flight when constant visual monitoring of the environment is unnecessary. Nevertheless, the reduction in muscle tone that usually accompanies REM sleep makes it unlikely that birds enter this state in flight. Upon landing, birds may need to recover the components of sleep that are incompatible with flight. Periods of undisturbed postflight recovery sleep may be essential for maintaining adaptive brain function during wakefulness. The recent miniaturization of EEG recording devices now makes it possible to measure brain activity in flight. Determining if and how birds sleep in flight will contribute to our understanding of a largely unexplored aspect of avian behavior and may also provide insight into the function of sleep.

  7. Bizarre tubercles on the vertebrae of Eocene fossil birds indicate an avian disease without modern counterpart

    Science.gov (United States)

    Mayr, Gerald

    2007-08-01

    Remains of fossil birds with numerous bony tubercles on the cervical vertebrae are reported from the Middle Eocene of Messel in Germany and the Late Eocene of the Quercy fissure fillings in France. These structures, which are unknown from extant birds and other vertebrates, were previously described for an avian skeleton from Messel but considered a singular feature of this specimen. The new fossils are from a different species of uncertain phylogenetic affinities and show that tuberculated vertebrae have a wider taxonomic, temporal, and geographic distribution. In contrast to previous assumptions, they are no ontogenetic feature and arise from the vertebral surface. It is concluded that they are most likely of pathologic origin and the first record of a Paleogene avian disease. Their regular and symmetrical arrangement over most of the external vertebral surface indicates a systemic disorder caused by factors that do not affect extant birds, such as especially high-dosed phytohormones or extinct pathogens.

    Recent studies suggest that besides the long-known farmer's lung antigen sources Saccharopolyspora rectivirgula (Micropolyspora faeni), Thermoactinomyces vulgaris, and Aspergillus fumigatus, additionally the mold Absidia (Lichtheimia) corymbifera as well as the bacteria Erwinia herbicola (Pantoea agglomerans) and Streptomyces albus may cause farmer's lung in Germany. In this study the sera of 64 farmers with a suspicion of farmer's lung were examined for the following further antigens: Wallemia sebi, Cladosporium herbarum, Aspergillus versicolor, and Eurotium amstelodami. Our results indicate that these molds are not frequent causes of farmer's lung in Germany. PMID:22477566

    Backyard gallinaceous bird flocks may play an important role in the spread of infectious diseases within poultry populations as well as the transmission of zoonotic diseases to humans. An epidemiologic characterization was conducted of Colorado backyard flocks to gather information on general flock characteristics, human movement of birds, human-bird interaction, biosecurity practices, and flock health. Our results suggest that backyard poultry flocks in Colorado are small-sized flocks (68.6% of flocks had production for the family (86.44%) or as pet or hobby birds (42.27%). The backyard flock environment may promote bird-to-bird transmission as well as bird-to-human transmission of infectious disease. Birds are primarily housed with free access to the outside (96.85%), and many are moved from the home premises (46.06% within 1 yr). Human contact with backyard flocks is high, biosecurity practices are minimal, and bird health is negatively impacted by increased movement events. Increased knowledge of backyard bird characteristics and associated management practices can provide guidelines for the development of measures to decrease disease transmission between bird populations, decrease disease transmission from birds to humans, and increase the overall health of backyard birds.

    Staphylococcus aureus was isolated from internal organs of 13 different psittacine birds submitted for necropsy over a period of 6 years. The birds all had lesions consistent with septicaemia. S. aureus isolates included three different phage types. In seven of the 13 birds, concurrent infections with Chlamydophila species, Enterococcus hirae, Candida species, unidentified streptococci and coagulasenegative staphylococci were detected. One bird also had lesions of lymphoid leucosis. Few indications were found that staphylococcosis associated problems may spread epidemically. The present studies suggest that S. aureus is pathogenic for psittacine birds, although it does not seem to be a frequent cause of disease. PMID:19184832

Those ambitious goals imply to be able to cut by half the demand for primary energy by 2050 which will be only possible if the need for building heating is cut by 80%, the constraint on transport is less important: one million of electrical vehicles will have to be on the road by 2020 and 3 millions 10 years later. In 2012 the production of electricity was made mainly from coal (44.7%), renewable energies (21.9%), nuclear energy (16%), natural gas (11.3%) and other energies (fuel...) (6.1%). Today the renewable energy sector is a major industrial sector in Germany, it represents about 382000 jobs directly or indirectly, it means more than the sector of conventional energies. (A.C.)

    Methods and importance of the measurement of dust precipitation and its metallic components are discussed. Test programs and results of heavy metal measurements in precipitations in Germany are summarized. The focus is on measurements of lead and cadmium. There is a clearly decreasing trend also seen in long-term test programs. The limiting values set in the Clean Air Act were hardly ever exceeded in recent years. (orig.)

    Avian bornaviruses (ABV) are known to be the causative agent of proventricular dilatation disease (PDD) in parrots and their relatives (Psittaciformes). A broad range of ABV genotypes has been detected not only in psittacine birds, but also in other avian species including canary birds (Serinus canaria forma domestica) and Bengalese finches (Lonchura striata f. dom.), which are both members of the order songbirds (Passeriformes). During this study 286 samples collected from captive and wild birds of various passerine species in different parts of Germany were screened for the presence of ABV. Interestingly, only three ABV-positive samples were identified by RT-PCR. They originated from one yellow-winged pytilia (Pytilia hypogrammica) and two black-rumped waxbills (Estrilda troglodytes) from a flock of captive estrildid finches in Saxony. The ABV isolates detected here were only distantly related to ABV isolates found in passerine species in Germany and Japan and form a new genotype tentatively called ABV-EF (for "estrildid finches").

    At a time of unprecedented biodiversity loss, researchers are increasingly recognizing the broad range of benefits provided to humankind by nature. However, as people live more urbanized lifestyles there is a progressive disengagement with the natural world that diminishes these benefits and discourages positive environmental behaviour. The provision of food for garden birds is an increasing global phenomenon, and provides a readily accessible way for people to counter this trend. Yet despite its popularity, quite why people feed birds remains poorly understood. We explore three loosely defined motivations behind bird feeding: that it provides psychological benefits, is due to a concern about bird welfare, and/or is due to a more general orientation towards nature. We quantitatively surveyed households from urban towns in southern England to explore attitudes and actions towards garden bird feeding. Each household scored three Likert statements relating to each of the three motivations. We found that people who fed birds regularly felt more relaxed and connected to nature when they watched garden birds, and perceived that bird feeding is beneficial for bird welfare while investing time in minimising associated risks. Finally, feeding birds may be an expression of a wider orientation towards nature. Overall, we found that the feelings of being relaxed and connected to nature were the strongest drivers. As urban expansion continues both to threaten species conservation and to change peoples' relationship with the natural world, feeding birds may provide an important tool for engaging people with nature to the benefit of both people and conservation.

    Marius Somveille

    Full Text Available Nearly one in five bird species has separate breeding and overwintering distributions, and the regular migrations of these species cause a substantial seasonal redistribution of avian diversity across the world. However, despite its ecological importance, bird migration has been largely ignored in studies of global avian biodiversity, with few studies having addressed it from a macroecological perspective. Here, we analyse a dataset on the global distribution of the world's birds in order to examine global spatial patterns in the diversity of migratory species, including: the seasonal variation in overall species diversity due to migration; the contribution of migratory birds to local bird diversity; and the distribution of narrow-range and threatened migratory birds. Our analyses reveal a striking asymmetry between the Northern and Southern hemispheres, evident in all of the patterns investigated. The highest migratory bird diversity was found in the Northern Hemisphere, with high inter-continental turnover in species composition between breeding and non-breeding seasons, and extensive regions (at high latitudes where migratory birds constitute the majority of the local avifauna. Threatened migratory birds are concentrated mainly in Central and Southern Asia, whereas narrow-range migratory species are mainly found in Central America, the Himalayas and Patagonia. Overall, global patterns in the diversity of migratory birds indicate that bird migration is mainly a Northern Hemisphere phenomenon. The asymmetry between the Northern and Southern hemispheres could not have easily been predicted from the combined results of regional scale studies, highlighting the importance of a global perspective.

    Full Text Available The purpose of this article is to give international readers an overview of the organisation, structure and curriculum, together with important advances and problems, of undergraduate medical education in Germany. Interest in medical education in Germany has been relatively low but has gained momentum with the new "Regulation of the Licensing of Doctors" which came into effect in 2003. Medical education had required substantial reform, particularly with respect to improving the links between theoretical and clinical teaching and the extension of interdisciplinary and topic-related instruction. It takes six years and three months to complete the curriculum and training is divided into three sections: basic science (2 years, clinical science (3 years and final clinical year. While the reorganisation of graduate medical education required by the new "Regulation of the Licensing of Doctors" has stimulated multiple excellent teaching projects, there is evidence that some of the stipulated changes have not been implemented. Indeed, whether the medical schools have complied with this regulation and its overall success remains to be assessed systematically. Mandatory external accreditation and periodic reaccreditation of medical faculties need to be established in Germany.

  14. Chemical compass for bird navigation

    Migratory birds travel spectacular distances each year, navigating and orienting by a variety of means, most of which are poorly understood. Among them is a remarkable ability to perceive the intensity and direction of the Earth's magnetic field. Biologically credible mechanisms for the detection...... other relies on the quantum spin dynamics of transient photoinduced radical pairs. Originally suggested by Schulten in 1978 as the basis of the avian magnetic compass sensor, this mechanism gained support from the subsequent observation that the compass is light-dependent. The radical pair hypothesis...... began to attract increased interest following the proposal in 2000 that free radical chemistry could occur in the bird's retina initiated by photoexcitation of cryptochrome, a specialized photoreceptor protein. In the present paper we review the important physical and chemical constraints on a possible...

    The DNA-binding protein PRDM9 has a critical role in specifying meiotic recombination hotspots in mice and apes, but it appears to be absent from other vertebrate species, including birds. To study the evolution and determinants of recombination in species lacking the gene that encodes PRDM9, we inferred fine-scale genetic maps from population resequencing data for two bird species: the zebra finch, Taeniopygia guttata, and the long-tailed finch, Poephila acuticauda. We found that both species have recombination hotspots, which are enriched near functional genomic elements. Unlike in mice and apes, most hotspots are shared between the two species, and their conservation seems to extend over tens of millions of years. These observations suggest that in the absence of PRDM9, recombination targets functional features that both enable access to the genome and constrain its evolution. PMID:26586757

  16. Wind power report Germany 2014

    International Nuclear Information System (INIS)

    Record year 2014. In Germany, the expansion figures attained were so high on land and at sea that the overall new installation figure of 5,188 MW surpassed the previous maximum (from 2002) by more than 60%. With an overall capacity of 39,259 MW, for the first time, wind energy in Germany covers 9.7% of gross power consumption. On the global scale a capacity of more than 51,000 MW has been added - another record high for wind energy installations. Power mix. At 161 TWh, renewable energies in Germany covered 27.8% of gross power consumption and provided for the first time more energy than any other energy source. Coming into force of the new REA in August 2014, modified support schemes caused the expansion of biogas plants and large-scale PV installations to falter. The record expansion seen for wind energy can be interpreted as a pull-forward effect due to the tender procedures coming into force in 2017. Grid integration. Loss of production caused by feed-in management measures rose by 44% to 555 GWh as compared to 2012. Wind turbines were affected in 87% of cases but the impact on PV installations is increasing. Power generation must be more flexible and grids expanded to limit loss of production. Of the 23 expansion projects (1,887 km) in the Electricity Grid Expansion Act, just a quarter of them had been realized by the end of 2014 (463 km). In the preliminary analysis results for the 2014 grid development plan, the extent of grid upgrading and conversion was 3050 km. Offshore, the HelWin 1 grid link with a capacity of 580 MW went online. SylWin 1 and BorWin 2, with a total capacity of 1660 MW, are currently being tested in a trial. In the preliminary analysis results for the 2014 offshore grid development plan, grid connections having an overall capacity of 10.3 GW are planned. Onshore. 2014 saw a total of 44 different turbine types installed in Germany. For the first time, virtually the same number of turbines were added in the 3-4 MW class, as in the 2-3 MW

    Avian migration, which involves billions of birds flying vast distances, is known to influence all aspects of avian life. Here we investigate how birds fit moult into an annual cycle determined by the need to migrate. Large variation exists in moulting patterns in relation to migration: for instance, moult can occur after breeding in the summer or after arrival in the wintering quarters. Here we use an optimal annual routine model to investigate why this variation exists. The modelled bird's ...

  6. Green Light for Nocturnally Migrating Birds

    Directory of Open Access Journals (Sweden)

    Marcel R. Wernand

    2008-12-01

    Full Text Available The nighttime sky is increasingly illuminated by artificial light sources. Although this ecological light pollution is damaging ecosystems throughout the world, the topic has received relatively little attention. Many nocturnally migrating birds die or lose a large amount of their energy reserves during migration as a result of encountering artificial light sources. This happens, for instance, in the North Sea, where large numbers of nocturnally migrating birds are attracted to the many offshore platforms. Our aim is to develop bird-friendly artificial lighting that meets human demands for safety but does not attract and disorient birds. Our current working hypothesis is that artificial light interferes with the magnetic compass of the birds, one of several orientation mechanisms and especially important during overcast nights. Laboratory experiments have shown the magnetic compass to be wavelength dependent: migratory birds require light from the blue-green part of the spectrum for magnetic compass orientation, whereas red light (visible long-wavelength disrupts magnetic orientation. We designed a field study to test if and how changing light color influenced migrating birds under field conditions. We found that nocturnally migrating birds were disoriented and attracted by red and white light (containing visible long-wavelength radiation, whereas they were clearly less disoriented by blue and green light (containing less or no visible long-wavelength radiation. This was especially the case on overcast nights. Our results clearly open perspective for the development of bird-friendly artificial lighting by manipulating wavelength characteristics. Preliminary results with an experimentally developed bird-friendly light source on an offshore platform are promising. What needs to be investigated is the impact of bird-friendly light on other organisms than birds.

    2009-10-01

    Full Text Available A brief historical overview shows the mainstream development pattern in German silviculture and outlines the adjacent role of seminatural (naturally-oriented silviculture. The rationale for seminatural silviculture is discussed with reference to its ecological and economical aspects. Elements of seminatural silviculture of the Baden-Württemberg-concept are introduced. This concept is not purely a preservation strategy, but recognizes the importance of timber production. Some aspects of selection forest, which is a special case of uneven-aged forest with a long tradition in Southwest Germany, are discussed. As there are still a lot of even-aged (pure forests in Southwest Germany, transformation strategies towards uneven-aged mixed forests are shown with the aid of some examples. Criteria and indicators for seminatural silviculture which have to be developed on a regional or local scale, can be used as a basis for establishing a certification process for Southwest German forests. Seminatural silviculture is suited as a rational and  intergrating  silvicultural     system      to     fulfill     future     requirements     on     forests     in    a    dynamically changing world.

  12. Air crew monitoring in Germany

    International Nuclear Information System (INIS)

    Cosmic radiation at high altitudes, especially high energetic neutrons, significantly increases exposure to man. Pilots and flight attendants may receive annual effective doses comparable to doses received in occupations, in which ionising radiation is used or radioactive sources are handled. For this reason, the European Council Directive 96/29 EURATOM requires that air-crew members also be monitored for radiation protection. Flight personnel, receiving an effective dose from cosmic radiation of more than 1 mSv per year are subject to monitoring i.e. radiation exposure has to be assessed, limited and minimized. As the physical conditions causing cosmic radiation doses are well established, it is possible to calculate the expected radiation dose with sufficient accuracy. Several codes for this purpose are available. Since August 2003, the operators of airlines in Germany are obliged to assess the doses of their air crew personnel from cosmic radiation exposure and to minimise radiation exposure by means of appropriate work schedules, flight routes and flight profiles. Approx. 31 000 persons of 45 airlines are monitored by the German Radiation Protection Register. Gender, age and 3 different occupational categories are used to characterise different groups and their doses. The presentation will give an overview about the legislation and organisation of air crew monitoring in Germany and will show detailed statistical results from the first year of monitoring.

    2006-05-01

    The future as well as the past development of cancer incidents in Germany is of continuous importance for health policy. Cancer incidence data observed over more than 20 years are analysed by log-linear models with polynomial trend components. The estimated trend models are used for a trend extrapolation until the year 2020. Since cancer registration in Germany is not complete yet and does not cover the whole area of the country national incidences are estimated by the data of the existing complete regional cancer registries. In this way it can be assessed that the number of new cancer diseases increased from 270,000 cases in 1980 to 420,000 cases in 2002. Extrapolating the trends and taking into account the demographic prognosis of the German Federal Statistical Office 570,000 (version 1) or 590,000 (version 9) annual cancer cases are predicted for the year 2020. From 1980 to 2002 a decrease of cancer mortality was observed. If this trend continues until 2020, the number of deaths caused by cancer would decrease from 209,000 in 2002 to 153,000 (or 158,000) in 2020, although the number of cancer cases are predicted to increase. Assuming constant mortality rates the number of deaths caused by cancer would be much higher. PMID:16596362

  14. Recycling of plastics in Germany

    International Nuclear Information System (INIS)

    This article deals with the waste management of post-consumer plastics in Germany and its potential to save fossil fuels and reduce CO2 emissions. Since most experience is available for packaging, the paper first gives an overview of the legislative background and the material flows for this sector. Then recycling and recovery processes for plastics waste from all sectors are assessed in terms of their contribution to energy saving and CO2 abatement. Practically all the options studied show a better performance than waste treatment in an average incinerator which has been chosen as the reference case. High ecological benefits can be achieved by mechanical recycling if virgin polymers are substituted. The paper then presents different scenarios for managing plastic waste in Germany in 1995: considerable savings can be made by strongly enhancing the efficiency of waste incinerators. Under these conditions the distribution of plastics waste among mechanical recycling, feedstock recycling and energy recovery has a comparatively mall impact on the overall results. The maximum savings amount to 74 PJ of energy, i.e, 9% of the chemical sector energy demand in 1995 and 7.0 Mt CO2, representing 13% of the sector's emissions. The assessment does not support a general recommendation of energy recovery due to the large difference between the German average and the best available municipal waste-to-energy facilities and also due to new technological developments in the field of mechanical recycling

    2010-02-01

    Birds are traditionally classified as male or female based on their anatomy and plumage color as judged by the human eye. Knowledge of a bird's gender is important for the veterinary practitioner, the owner and the breeder. The accurate gender determination is essential for proper pairing of birds, and knowing the gender of a bird will allow the veterinarian to rule in or out gender-specific diseases. Several biochemical methods of gender determination have been developed for avian species where otherwise the gender of the birds cannot be determined by their physical appearances or characteristics. In this contribution, we demonstrate that FT-IR spectroscopy is a suitable tool for a quick and objective determination of the bird's gender. The method is based on differences in chromosome size. Male birds have two Z chromosomes and female birds have a W-chromosome and a Z-chromosome. Each Z-chromosome has approx. 75.000.000 bps whereas the W-chromosome has approx. 260.00 bps. This difference can be detected by FT-IR spectroscopy. Spectra were recorded from germ cells obtained from the feather pulp of chicks as well as from the germinal disk of fertilized but non-bred eggs. Significant changes between cells of male and female birds occur in the region of phosphate vibrations around 1080 and 1120 cm-1.

    The purpose of this paper is to review the results in the literature that show the effect of area of forest on nesting migratory bird species, and to present the results of additional field work that we have conducted in forest habitats in western Maryland. These results indicate the area sensitivity of many long distance migrants. Because 80 to 95 percent of the breeding birds in the northeastern deciduous forest are neotropical migrants, the changes in bird species composition as a result of forest fragmentation can be immense. Management strategies based on habitat size are suggested to assist in maintaining communities of nesting migratory birds.

Overall, 992 citizen scientists collected data over two, four-week survey periods during winter 2014 and summer 2015 (43% participated in both years. Avian assemblages at urban and rural bird baths differed between bioregions with aggressive nectar-eating species influenced the avian assemblages visiting urban bird baths in South Eastern Queensland, NSW North Coast and Sydney Basin while introduced birds contributed to differences in South Western Slopes, Southern Volcanic Plains and Victorian Midlands. Small honeyeaters and other small native birds occurred less often at urban bird baths compared to rural bird baths. Our results suggest that differences between urban versus rural areas, as well as bioregion, significantly influence the composition of avian assemblages visiting bird baths in private gardens. We also demonstrate that citizen science monitoring of fixed survey sites such as bird baths is a useful tool in understanding large-scale patterns in avian assemblages which requires a vast amount of data to be collected across broad areas.

    Full Text Available Indian subcontinent plays host to a number of migratory birds in summers as well as winters. It is estimated that over hundred species of migratory birds fly to India, either in search of feeding grounds or to escape the severe winter of their native habitat. Sandi bird sanctuary was created in 1990 in order to protect and conserve the natural habitation and surroundings and also the marine vegetation for the migratory birds, as well as for the local people of the region. The term migration is used to describe movements of populations of birds or other animals. There are three types of migrants. One way to look at migration is to consider the distances traveled. The pattern of migration can vary within each category, but is most variable in short and medium distance migrants. The origin of migration is related to the distance traveled. The birds migrating through the area, take shelter on the river front before going to the Sandi Bird sanctuary. The birds generally migrate in the winter months of October-November-December. Bird sanctuary is a popular tourist location. Sandi particularly attracts ornithologists and bird watchers, as many rare migratory birds take refuge in the sanctuary. The bird watching camps arranged to observe the migratory birds at Sandi Bird Sanctuary in the month of October and November 2012. The migratory birds at Sandi Bird Sanctuary include great crested grebe, white storks, black lbis, glossy lbis, spoonbill, ruddy shelduck, pin tail, sholveller, spot bill duck, mallard, gadwall, wigeon, tufted pochard, gargancey teal, common teal, cotton teal, grey lag goose, coot, black tailed godwit, painted stock pin tail snipe, marsh sand piper, common tern, river tern, magpie robin, white wagtail, pied wagtail, common snipe, starlings, white lbis, red crested pochard, common pochard, painted stock, black lbis, curlew, Indian skimmer etc. The resident birds at Sandi Bird Sanctuary include little grebe, darter, purple heron, grey

  5. Top-down control of herbivory by birds and bats in the canopy of temperate broad-leaved oaks (Quercus robur.

    Directory of Open Access Journals (Sweden)

    Stefan M Böhm

    Full Text Available The intensive foraging of insectivorous birds and bats is well known to reduce the density of arboreal herbivorous arthropods but quantification of collateral leaf damage remains limited for temperate forest canopies. We conducted exclusion experiments with nets in the crowns of young and mature oaks, Quercus robur, in south and central Germany to investigate the extent to which aerial vertebrates reduce herbivory through predation. We repeatedly estimated leaf damage throughout the vegetation period. Exclusion of birds and bats led to a distinct increase in arthropod herbivory, emphasizing the prominent role of vertebrate predators in controlling arthropods. Leaf damage (e.g., number of holes differed strongly between sites and was 59% higher in south Germany, where species richness of vertebrate predators and relative oak density were lower compared with our other study site in central Germany. The effects of bird and bat exclusion on herbivory were 19% greater on young than on mature trees in south Germany. Our results support previous studies that have demonstrated clear effects of insectivorous vertebrates on leaf damage through the control of herbivorous arthropods. Moreover, our comparative approach on quantification of leaf damage highlights the importance of local attributes such as tree age, forest composition and species richness of vertebrate predators for control of arthropod herbivory.

  6. History of anesthesia in Germany.

    Wawersik, J

    1991-01-01

    The first ether anesthetic was administered in Germany by J.F. Heyfelder (1798-1869) at the Erlangen University Hospital on January 24, 1847. Thereafter, famous discoveries occurred in the field of pharmacology. Albert Niemann isolated cocaine from the coca shrub in 1860; Emil Fischer synthesized the first barbiturate, Veronal, in 1902; and Helmut Weese promoted the first ultra-short-acting barbiturate, hexobarbital (Evipan), in 1932. The local anesthetic effect of cocaine was reported by Koller at the Congress of the German Society for Ophthalmology on September 15, 1884, in Heidelberg. Many new techniques were tried first in German hospitals. Friedrich Trendelenburg carried out, by tracheotomy, the first operation with endotracheal intubation in 1869, and Franz Kuhn promoted and clinically practiced endotracheal intubation in Heidelberg beginning in 1900. August Bier performed the first operation under spinal anesthesia at the Kiel University Hospital on August 16, 1898. Carl Ludwig Schleich (1859-1922) standardized the methods of infiltration anesthesia by using a cocaine solution in sufficient dilution. The development of anesthesia machines was greatly influenced by Heinrich Dräger (1847-1917) and his son Bernhard Dräger (1870-1928). The Dräger Company in Lübeck built the first anesthesia machine with a carbon dioxide (CO2) absorber and circle system in 1925. Paul Sudeck and Helmut Schmidt worked with this system at the Hamburg University Hospital and reported their results in 1926. The first Dräger anesthesia machine was produced in 1902 and introduced into clinical use by Otto Roth (1863-1944) in Lübeck. Before the Second World War, three universities in Germany carried out research in the field of anesthesia: the University of Freiburg with H. Killian, the University of Hamburg with P. Sudeck and H. Schmidt, and the University of Würzburg with C.G. Gauss. Killian and Gauss established the first journals, Der Schmerz and Narkose und Anaesthesie, in

    In response to the Deepwater Horizon oil spill in spring 2010, the Natural Resources Conservation Service implemented the Migratory Bird Habitat Initiative (MBHI) to provide temporary wetland habitat for migrating and wintering waterfowl, shorebirds, and other birds along the northern Gulf of Mexico via managed flooding of agricultural lands. We used weather-surveillance radar to conduct broad regional assessments of bird response to MBHI activities within the Mississippi Alluvial Valley and the West Gulf Coastal Plain. Across both regions, birds responded positively to MBHI management by exhibiting greater relative bird densities within sites relative to pre-management conditions in prior years and relative to surrounding non-flooded agricultural lands. Bird density at MBHI sites was generally greatest during winter for both regions. Unusually high flooding in the years prior to implementation of the MBHI confounded detection of overall changes in remotely sensed soil wetness across sites. The magnitude of bird response at MBHI sites compared to prior years and to non-flooded agricultural lands was generally related to the surrounding landscape context: proximity to areas of high bird density, amount of forested wetlands, emergent marsh, non-flooded agriculture, or permanent open water. However, these relationships varied in strength and direction between regions and seasons, a finding which we attribute to differences in seasonal bird composition and broad regional differences in landscape configuration and composition. We detected greater increases in relative bird use at sites in closer proximity to areas of high bird density during winter in both regions. Additionally, bird density was greater during winter at sites with more emergent marsh in the surrounding landscape. Thus, bird use of managed wetlands could be maximized by enrolling lands located near areas of known bird concentration and within a mosaic of existing wetlands. Weather-radar observations

    1991-01-01

    The Breeding Bird Survey (BBS) and Bird Banding Laboratory (BBL) are sources of information for raptor biologists. The BBS has been conducted each year since 1966 in the United States and Canada; historical bird banding records extend back to the early 20th century. BBS data can be used to document population trends and breeding distributions of many bird species. Banding data are generally collected for specific and local studies of bird populations or behavior. Past use of these data has been limited by their volume and relative inaccessibility. In this paper, we present an overview of BBS and BBL raptor data and their uses, limitations and availability.

  11. Waste management strategy in Germany

    The Federal Republic of Germany intends to dispose of all types of radioactive waste in deep geological formations. The Federal Government made a pronounced change in energy policy since 1998, the most important feature of which is phasing out of nuclear energy, finally set in force by the April 2002 amendment of the Atomic Energy Act. According to the new approach to waste management and disposal, further sites in various host rocks shall be investigated for their suitability based on repository site selection criteria and respective procedures developed by a special expert group. The objective of the site selection procedure is to identify with public participation potential disposal sites in a comprehensible and reliable way. (author)

    Bird strikes present a huge risk for air ve-hicles, especially since traditional airport bird surveillance is mainly dependent on inefficient human observation. For improving the effectiveness and efficiency of bird monitor-ing, computer vision techniques have been proposed to detect birds, determine bird flying trajectories, and pre-dict aircraft takeoff delays. Flying bird with a huge de-formation causes a great challenge to current tracking al-gorithms. We propose a segmentation based approach to enable tracking can adapt to the varying shape of bird. The approach works by segmenting object at a region of inter-est, where is determined by the object localization method and heuristic edge information. The segmentation is per-formed by Markov random field, which is trained by fore-ground and background mixture Gaussian models. Exper-iments demonstrate that the proposed approach provides the ability to handle large deformations and outperforms the m ost state-of-the-art tracker in the infrared flying bird tracking problem.

    Recent discoveries of spectacular dinosaur fossils overwhelmingly support the hypothesis that birds are descended from maniraptoran theropod dinosaurs, and furthermore, demonstrate that distinctive bird characteristics such as feathers, flight, endothermic physiology, unique strategies for reproduction and growth, and a novel pulmonary system originated among Mesozoic terrestrial dinosaurs. The transition from ground-living to flight-capable theropod dinosaurs now probably represents one of the best-documented major evolutionary transitions in life history. Recent studies in developmental biology and other disciplines provide additional insights into how bird characteristics originated and evolved. The iconic features of extant birds for the most part evolved in a gradual and stepwise fashion throughout archosaur evolution. However, new data also highlight occasional bursts of morphological novelty at certain stages particularly close to the origin of birds and an unavoidable complex, mosaic evolutionary distribution of major bird characteristics on the theropod tree. Research into bird origins provides a premier example of how paleontological and neontological data can interact to reveal the complexity of major innovations, to answer key evolutionary questions, and to lead to new research directions. A better understanding of bird origins requires multifaceted and integrative approaches, yet fossils necessarily provide the final test of any evolutionary model. PMID:25504729

  19. Bird feeders and their effects on bird-window collisions at residential houses

    Justine A. Kummer

    2015-12-01

    Full Text Available Feeding wild birds creates an important link between homeowners and conservation. The effects of bird feeders and year-round feeding on birds have not been well studied, however, particularly in relationship to bird-window collisions. We determined effects of bird feeder presence and placement on bird-window collisions at residential homes. Paired month-long trials in which a feeder was either present or absent for one month and then removed or added for the second month were completed at 55 windows at 43 houses. In each trial, homeowners were asked to search their study window daily for evidence of a bird-window collision. During the study there were 51 collisions when there was no bird feeder and 94 when the feeder was present. The season when each trial was set up was the best individual predictor of bird-window collisions. The largest number of collisions was observed during fall migration and the lowest during the winter months. There were no collisions at 26 of the study windows. High variance was observed in the number of collisions at different houses, indicating that effects of bird feeders are context dependent. Changing the occurrence, timing, and placement of feeders can alter collision rates but is only one of many factors that influence whether a residential house is likely to have a bird window-collision or not.

  20. Ionizing radiation and wild birds: a review

    International Nuclear Information System (INIS)

    Since the first atomic explosion, 16 July 1945 at the Trinity Site in south-central New Mexico, the impact of ionizing radiation on bird populations has been of concern to a few individuals. The proliferation of nuclear power plants has increased public concern as to possible deleterious effects of nuclear power plant operation on resident and migratory bird populations. Literature involving wild birds and ionizing radiation is not readily available, and only a few studies have been anywhere near comprehensive, with most effort directed towards monitoring radionuclide concentration in birds. The objective of the paper is to document the literature on wild birds and ionizing radiation including a brief description of pertinent papers

    International Nuclear Information System (INIS)

    Microscopical examinations are useful in detecting bacteria from droppings and body fluids. Antimicrobial susceptibility tests are also used to perform antimicrobial therapy. Parasitological examinations can also be done on pet birds. Hematological examinations are not very common because of the difficulties in determining the normal serum values that might vary by species and sexes. The vena cutanea ulnaris is the best vein for drawing blood from a pet bird but nail clipping for this purpose is also widely used. The most common and basic complementary examination method is radiology. Birds can be radiographed without anesthesia. Ventrodorsal and latero-lateral pictures are required. The right positioning and setting the adequate values is the most important. Contrast radiographs can also be made on birds. Endoscopy is widely used for sex determination but also can be used for the examination of abdominal organs. Ultrasound examination of pet birds is not a common method because of the difficulties provided by the air sacs. ECG is not a widely used method either because of the high heart beat frequency of birds. Other methods such as necropsy, cytological, histological and toxicological examinations can also be performed on pet birds

    2004-01-01

    Antibodies to West Nile virus were detected in 94 of 1,784 Illinois birds during 2002. Captive and urban birds had higher seropositivity than did birds from natural areas, and northern and central Illinois birds’ seropositivity was greater than that from birds from the southern sites. Adult and hatch-year exposure rates did not differ significantly.

  3. Freeze-frame fruit selection by birds

    Science.gov (United States)

    Foster, Mercedes S.

    2008-01-01

    The choice of fruits by an avian frugivore is affected by choices it makes at multiple hierarchical levels (e.g., species of fruit, individual tree, individual fruit). Factors that influence those choices vary among levels in the hierarchy and include characteristics of the environment, the tree, and the fruit itself. Feeding experiments with wild-caught birds were conducted at El Tirol, Departamento de Itapua, Paraguay to test whether birds were selecting among individual fruits based on fruit size. Feeding on larger fruits, which have proportionally more pulp, is generally more efficient than feeding on small fruits. In trials (n = 56) with seven species of birds in four families, birds selected larger fruits 86% of the time. However, in only six instances were size differences significant, which is likely a reflection of small sample sizes.

  7. Causes of hatching failure in endangered birds

    2012-01-01

    About 10 per cent of birds' eggs fail to hatch, but the incidence of failure can be much higher in endangered species. Most studies fail to distinguish between infertility (due to a lack of sperm) and embryo mortality as the cause of hatching failure, yet doing so is crucial in order to understand the underlying problem. Using newly validated techniques to visualize sperm and embryonic tissue, we assessed the fertility status of unhatched eggs of five endangered species, including both wild and captive birds. All eggs were classified as ‘infertile’ when collected, but most were actually fertile with numerous sperm on the ovum. Eggs of captive birds had fewer sperm and were more likely to be infertile than those of wild birds. Our findings raise important questions regarding the management of captive breeding programmes.

  17. Are there optimal densities for prairie birds?

    Science.gov (United States)

    Skagen, S.K.; Adams, A.A.Y.

    2010-01-01

    The major forces of food and predation shape fitness-enhancing decisions of birds at all stages of their life cycles. During the breeding season, birds can minimize nest loss due to predation by selecting sites with a lower probability of predation. To understand the environmental and social aspects and consequences of breedingsite selection in prairie birds, we explored variation in nest-survival patterns of the Lark Bunting (Calamospiza melanocorys) in the shortgrass prairie region of North America. Over four breeding seasons, we documented the survival of 405 nests, conducted 60 surveys to estimate bird densities, and measured several vegetative features to describe habitat structure in 24 randomly selected study plots. Nest survival varied with the buntings' density as described by a quadratic polynomial, increasing with density below 1.5 birds ha-1 and decreasing with density between 1.5 and 3 birds ha-1, suggesting that an optimal range of densities favors reproductive success of the Lark Bunting, which nests semi-colonially. Nest survival also increased with increasing vegetation structure of study plots and varied with age of the nest, increasing during early incubation and late in the nestling stage and declining slightly from mid-incubation to the middle of the nestling period. The existence of an optimal range of densities in this semi-colonial species can be elucidated by the "commodity-selection hypothesis" at low densities and density dependence at high densities. ??

    seen in infected birds. Transmission of infection to humans occurs through inhalation or direct contact and transmission through bird bites or human-to-human is rare. C. psittaci usually leads to the systemic infection associated with pneumonia in humans. In recent years, PCR based molecular methods are used as well as serological methods such as ELISA, CFT, MIF in diagnosis. Both of infected birds and humans, tetracyclines and macrolides are preferred for treatment of infection. In order to prevent the disease, due to there isn't any commercial vaccine for especially using in birds, applying biosafety rules is very important in terms of human health and economical aspects. Especially, veterinarians, bird breeders and dealers, poultry farmers and slaughterhouse workers are at high risk for C. psittaci infection. Due to the transmission to humans of psittacosis infection and accepting it as a potential biological weapon, it is thought to be important for public health. In this review, it is aimed to give detailed information about infection in human and birds, because it can be missed at the diagnosis, hence there is low awareness about disease and it has got variable clinical symptoms.

  20. Jinfengopteryx Compared to Archaeopteryx, with Comments on the Mosaic Evolution of Long-tailed Avialan Birds

    Institute of Scientific and Technical Information of China (English)

    JI Shu'an; JI Qiang

    2007-01-01

    Jinfengopteryx is a newly uncovered Archaeopteryx-like avialan bird outside Germany, which was found from the Jehol Biota of northern Hebei in northeastern China. It shares many characters only with Archaeopteryx by the possession of three fenestrae in the antorbital cavity, 23 caudal vertebrae and long tail feathers attached to all the caudal vertebrae. But the former differs from the latter in the relatively short and high preorbital region of skull, more and closely packed teeth, much shorter forelimb compared to hindlimb. Such differences indicate Jinfengopteryx is even slightly more primitive than Archaeopteryx, although both birds can be placed at the root position of the avialan tree based on cladistic analysis. Shenzhouraptor is suggested to be slightly more advanced than Jinfengopteryx + Archaeopteryx, supported by some derived features in teeth, shoulder girdles and forelimbs such as the reduction of tooth number, dorsolaterally directed glenoid facet, very long forelimb and comparatively short manus. Meanwhile, the tail of Shenzhouraptor shows more primitive characters than those of Jinfengopteryx and Archaeopteryx, e.g., the strikingly longer tail composed of more caudal vertebrae and the long tail feathers attached only to distal caudal segments. The mixed primitive and advanced characters reveal the evident mosaic evolution among long-tailed avialan birds.

    Climate changes are expected to affect bird migration in several aspects including timing changes, breeding and migration orientation. The correlation analysis of several climate conditions (e.g. temperature, wind, humidity, etc) and bird migration trajectory is the key for explaining bird behavior during migration. Moreover, the resulting correlation can be used for predicting new bird behavior according to climate changes. In this paper we propose an integrated solution for correlating bird...

  2. The Flight of Birds and Other Animals

    Directory of Open Access Journals (Sweden)

    Colin J. Pennycuick

    2015-09-01

    Full Text Available Methods of observing birds in flight now include training them to fly under known conditions in wind tunnels, and fitting free-flying birds with data loggers, that are either retrieved or read remotely via satellite links. The performance that comes to light depends on the known limitations of the materials from which they are made, and the conditions in which the birds live. Bird glide polars can be obtained by training birds to glide in a tilting wind tunnel. Translating these curves to power required from the flight muscles in level flight requires drag coefficients to be measured, which unfortunately does not work with bird bodies, because the flow is always fully detached. The drag of bodies in level flight can be determined by observing wingbeat frequency, and shows CD values around 0.08 in small birds, down to 0.06 in small waders specialised for efficient migration. Lift coefficients are up to 1.6 in gliding, or 1.8 for short, temporary glides. In-flight measurements can be used to calculate power curves for birds in level flight, and this has been applied to migrating geese in detail. These typically achieve lift:drag ratios around 15, including allowances for stops, as against 19 for continuous powered flight. The same calculations, applied to Pacific Black-tailed Godwits which start with fat fractions up to 0.55 at departure, show that such birds not only cross the Pacific to New Zealand, but have enough fuel in hand to reach the South Pole if that were necessary. This performance depends on the “dual fuel” arrangements of these migrants, whereby they use fat as their main fuel, and supplement this by extra fuel from burning the engine (flight muscles, as less power is needed later in the flight. The accuracy of these power curves has never been checked, although provision for stopping the bird, and making these checks at regular intervals during a simulated flight was built into the original design of the Lund wind tunnel.

  4. Chernobyl birds have smaller brains.

    Directory of Open Access Journals (Sweden)

    Anders Pape Møller

    Full Text Available BACKGROUND: Animals living in areas contaminated by radioactive material from Chernobyl suffer from increased oxidative stress and low levels of antioxidants. Therefore, normal development of the nervous system is jeopardized as reflected by high frequencies of developmental errors, reduced brain size and impaired cognitive abilities in humans. Alternatively, associations between psychological effects and radiation have been attributed to post-traumatic stress in humans. METHODOLOGY/PRINCIPAL FINDING: Here we used an extensive sample of 550 birds belonging to 48 species to test the prediction that even in the absence of post-traumatic stress, there is a negative association between relative brain size and level of background radiation. We found a negative association between brain size as reflected by external head volume and level of background radiation, independent of structural body size and body mass. The observed reduction in brain size in relation to background radiation amounted to 5% across the range of almost a factor 5,000 in radiation level. Species differed significantly in reduction in brain size with increasing background radiation, and brain size was the only morphological character that showed a negative relationship with radiation. Brain size was significantly smaller in yearlings than in older individuals. CONCLUSIONS/SIGNIFICANCE: Low dose radiation can have significant effects on normal brain development as reflected by brain size and therefore potentially cognitive ability. The fact that brain size was smaller in yearlings than in older individuals implies that there was significant directional selection on brain size with individuals with larger brains experiencing a viability advantage.

  6. A sonic net excludes birds from an airfield: implications for reducing bird strike and crop losses.

    Science.gov (United States)

    Swaddle, John P; Moseley, Dana L; Hinders, Mark K; Smith, Elizabeth P

    2016-03-01

    Collisions between birds and aircraft cause billions of dollars of damages annually to civil, commercial, and military aviation. Yet technology to reduce bird strike is not generally effective, especially over longer time periods. Previous information from our lab indicated that filling an area with acoustic noise, which masks important communication channels for birds, can displace European Starlings (Sturnus vulgaris) from food sources. Here we deployed a spatially controlled noise (termed a "sonic net"), designed to overlap with the frequency range of bird vocalizations, at an airfield. By conducting point counts, we monitored the presence of birds for four weeks before deployment of our sonic net, and for four weeks during deployment. We found an 82% reduction in bird presence in the sonic net area compared with change in the reference areas. This effect was as strong in the fourth week of exposure as in the first week. We also calculated the potential costs avoided resulting from this exclusion. We propose that spatially controlled acoustic manipulations that mask auditory communication for birds may be an effective long term and fairly benign way of excluding problem birds from areas of socioeconomic importance, such as airfields, agricultural sites, and commercial properties.

  7. Bird pollination of Canary Island endemic plants

    Ollerton, Jeff; Cranmer, Louise; Stelzer, Ralph J.; Sullivan, Steve; Chittka, Lars

    2009-02-01

    The Canary Islands are home to a guild of endemic, threatened bird-pollinated plants. Previous work has suggested that these plants evolved floral traits as adaptations to pollination by flower specialist sunbirds, but subsequently, they appear to have co-opted generalist passerine birds as sub-optimal pollinators. To test this idea, we carried out a quantitative study of the pollination biology of three of the bird-pollinated plants, Canarina canariensis (Campanulaceae), Isoplexis canariensis (Veronicaceae) and Lotus berthelotii (Fabaceae), on the island of Tenerife. Using colour vision models, we predicted the detectability of flowers to bird and bee pollinators. We measured pollinator visitation rates, nectar standing crops as well as seed-set and pollen removal and deposition. These data showed that the plants are effectively pollinated by non-flower specialist passerine birds that only occasionally visit flowers. The large nectar standing crops and extended flower longevities (>10 days) of Canarina and Isoplexis suggests that they have evolved a bird pollination system that effectively exploits these low frequency non-specialist pollen vectors and is in no way sub-optimal. Seed set in two of the three species was high and was significantly reduced or zero in flowers where pollinator access was restricted. In L. berthelotii, however, no fruit set was observed, probably because the plants were self-incompatible horticultural clones of a single genet. We also show that, while all three species are easily detectable for birds, the orange Canarina and the red Lotus (but less so the yellow-orange Isoplexis) should be difficult to detect for insect pollinators without specialised red receptors, such as bumblebees. Contrary to expectations if we accept that the flowers are primarily adapted to sunbird pollination, the chiffchaff ( Phylloscopus canariensis) was an effective pollinator of these species.

  8. Comparing aerodynamic efficiency in birds and bats suggests better flight performance in birds.

    Directory of Open Access Journals (Sweden)

    Florian T Muijres

    Full Text Available Flight is one of the energetically most costly activities in the animal kingdom, suggesting that natural selection should work to optimize flight performance. The similar size and flight speed of birds and bats may therefore suggest convergent aerodynamic performance; alternatively, flight performance could be restricted by phylogenetic constraints. We test which of these scenarios fit to two measures of aerodynamic flight efficiency in two passerine bird species and two New World leaf-nosed bat species. Using time-resolved particle image velocimetry measurements of the wake of the animals flying in a wind tunnel, we derived the span efficiency, a metric for the efficiency of generating lift, and the lift-to-drag ratio, a metric for mechanical energetic flight efficiency. We show that the birds significantly outperform the bats in both metrics, which we ascribe to variation in aerodynamic function of body and wing upstroke: Bird bodies generated relatively more lift than bat bodies, resulting in a more uniform spanwise lift distribution and higher span efficiency. A likely explanation would be that the bat ears and nose leaf, associated with echolocation, disturb the flow over the body. During the upstroke, the birds retract their wings to make them aerodynamically inactive, while the membranous bat wings generate thrust and negative lift. Despite the differences in performance, the wake morphology of both birds and bats resemble the optimal wake for their respective lift-to-drag ratio regimes. This suggests that evolution has optimized performance relative to the respective conditions of birds and bats, but that maximum performance is possibly limited by phylogenetic constraints. Although ecological differences between birds and bats are subjected to many conspiring variables, the different aerodynamic flight efficiency for the bird and bat species studied here may help explain why birds typically fly faster, migrate more frequently and migrate

  9. Ultra-Rapid Vision in Birds.

    Directory of Open Access Journals (Sweden)

    Jannika E Boström

    Full Text Available Flying animals need to accurately detect, identify and track fast-moving objects and these behavioral requirements are likely to strongly select for abilities to resolve visual detail in time. However, evidence of highly elevated temporal acuity relative to non-flying animals has so far been confined to insects while it has been missing in birds. With behavioral experiments on three wild passerine species, blue tits, collared and pied flycatchers, we demonstrate temporal acuities of vision far exceeding predictions based on the sizes and metabolic rates of these birds. This implies a history of strong natural selection on temporal resolution. These birds can resolve alternating light-dark cycles at up to 145 Hz (average: 129, 127 and 137, respectively, which is ca. 50 Hz over the highest frequency shown in any other vertebrate. We argue that rapid vision should confer a selective advantage in many bird species that are ecologically similar to the three species examined in our study. Thus, rapid vision may be a more typical avian trait than the famously sharp vision found in birds of prey.

  10. An introduction to Jade Bird Project

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    @@Jade Bird, a lucky and divine bird in ancient Chinese mythology, is a message deliverer in the world of gods. She serves goddess Xi Wang Mu (Western Queen), bringing her commands and messages to other gods. With 3 feet, black eyes and red head, this beautiful bird is viewed as a lucky symbol in China. There are a lot of tales about her in the folklore and literature. This is why Jade Bird was chosen as the name of the largest project for research on software technology in China. Jade Bird (JB) project, started in 1983 in the period of the 6th State Five_year Plan, is a key Sci.&Tech. project of the State. It has lasted more than 15 years through the 7th, 8th, and 9th State Five_year Plan periods and is the only software project getting continual support from the government. More than 20 institutions, 300 researchers and developers are involved in the development of JB Project. Prof. Yang Fuqing from Peking University, a member of the Chinese Academy of Sciences, is the leader and chief scientist of the project.

  11. Osedax borings in fossil marine bird bones

    Kiel, Steffen; Kahl, Wolf-Achim; Goedert, James L.

    2011-01-01

    The bone-eating marine annelid Osedax consumes mainly whale bones on the deep-sea floor, but recent colonization experiments with cow bones and molecular age estimates suggesting a possible Cretaceous origin of Osedax indicate that this worm might be able grow on a wider range of substrates. The suggested Cretaceous origin was thought to imply that Osedax could colonize marine reptile or fish bones, but there is currently no evidence that Osedax consumes bones other than those of mammals. We provide the first evidence that Osedax was, and most likely still is, able to consume non-mammalian bones, namely bird bones. Borings resembling those produced by living Osedax were found in bones of early Oligocene marine flightless diving birds (family Plotopteridae). The species that produced these boreholes had a branching filiform root that grew to a length of at least 3 mm, and lived in densities of up to 40 individuals per square centimeter. The inclusion of bird bones into the diet of Osedax has interesting implications for the recent suggestion of a Cretaceous origin of this worm because marine birds have existed continuously since the Cretaceous. Bird bones could have enabled this worm to survive times in the Earth's history when large marine vertebrates other than fish were rare, specifically after the disappearance of large marine reptiles at the end-Cretaceous mass extinction event and before the rise of whales in the Eocene.

    2016-03-01

    While the possibility of enacting a sui generis Biobank Act has been debated in Germany at great length, as of yet the country has not implemented any biobankspecific legislation. Instead, oversight is available via a network of research and privacy laws, including those of the European Union. The Nationale Kohorte, Germany's large-scale, population-based epidemiological research biobank, is funded by the Federal Ministry of Education and Research, and there are currently 108 registered bio-banks throughout Germany. The current system, including the structure and study design of the Nationale Kohorte, privileges the protection of personal information even at the cost of socially desirable research; it remains to be seen if forthcoming legislation will shift this balance.

  14. Cohabiting unions in France and West Germany

    Directory of Open Access Journals (Sweden)

    2002-12-01

    Full Text Available This paper compares the non-marital birth pattern in France and West Germany. Since the beginning of the eighties, France witnessed a steady increase in non-marital birth rates, while in West Germany non-marital birth rates have remained at a relatively low level. We attribute these differences to the institutional and legal constraints from both sides of the Rhine which hamper or foster childbearing in cohabiting unions. Using data from the French and German Family and Fertility Survey, we apply event history modeling to the transition to marriage and first birth. Our results indicate a polarization of family forms in both countries. In West Germany, we find a polarization in a "family sector" and a "non-family sector" while in France there is a polarization in a "marriage sector" and a "cohabiting sector".

    In this short paper an overlook is given of the systems developed in Germany for filtered containment venting and their implementation in nuclear power plants. More information on the development can be found in the Proceedings of the DOE/NRC Aircleaning Conferences. In Germany, 28.8 % of the electric energy is produced by 19 nuclear power reactors. No new power reactor is expected to be built at least within the next ten years, but France and Germany cooperate in the development of a future European Power Reactor (ERP). This reactor type will be fitted with a core catcher and passive cooling in order to avoid serious consequences of a hypothetical core meltdown accident so that provisions for containment venting are not required. 3 refs., 6 figs., 1 tab.

    In order to answer the question how a greenhouse gas neutral Germany would look like an interdisciplinary process was started by the Federal Environmental Agency. It was clear from the beginning of this work that a sustainable regenerative energy supply could not be sufficient. Therefore all relevant emission sources were included into the studies: traffic, industry, waste and waste water, agriculture, land usage, land usage changes and forestry. The necessary transformation paths to reach the aim of a greenhouse gas neutral Germany in 2050, economic considerations and political instruments were not part of this study.

    "The authors examine how the immigrant population of Germany has risen despite the fact that the German government has sought to restrict it. They analyze six major streams of migration: refugees and expellees who came immediately after World War II, German resettlers from Eastern Europe (¿Aussiedler'), emigration of (West) Germans, migration between East- and West Germany, foreign labor migrants and asylum seekers. The dynamics of immigration, the chances on the labor market, and the opportunities for social integration were remarkably different for each of these groups. As far as absorption and integration are concerned the authors argue that different groups of immigrants should be treated more equally." (EXCERPT) PMID:12348943

  1. Phase Transitions in Models of Bird Flocking

    Christodoulidi, H; Bountis, T

    2013-01-01

    The aim of the present paper is to elucidate the transition from collective to random behavior exhibited by various mathematical models of bird flocking. In particular, we compare Vicsek's model [Viscek et al., Phys. Rev. Lett. 75, 1226 -- 1229 (1995)] with one based on topological considerations. The latter model is found to exhibit a first order phase transition from flocking to decoherence, as the 'noise parameter' of the problem is increased, whereas Viscek's model gives a second order transition. Refining the topological model in such a way that birds are influenced mostly by the birds in front of them, less by the ones at their sides and not at all by those behind them (because they do not see them), we find a behavior that lies in between the two models. Finally, we propose a novel mechanism for preserving the flock's cohesion, without imposing artificial boundary conditions or attracting forces.

    Rapacious birds are the most threatened animals of Slovakia. Selected species are significant indicators of the state of the environment. Red kite (Milvus milvus) is the critically endangered species and the last 15 - 20 pairs are breeding in Slovakia now. White-tailed eagle (Haliaetus albicilla) nested in the basin of the Danube River until 1964. It was only after 34 years that two pairs of white-tailed eagle have successfully bred in the floodplain of the Danube River. Short-toed eagle (Circaettus gallicus), only 20-30 pairs are breeding in the eastern part of Slovakia. Golden eagle (Aquila chrysaetos) is one of the species most threatened by theft of eggs for its use in falconry and in different holdings. Eastern imperial eagle (Aquila heliaca) - about 30 to 40 pairs is breeding now in Slovakia. Spreading of the bird species is processed based in the data provided by the Group for Protection of Rapacious Birds. (author)

    Full Text Available Emu is the second largest living bird of world belonging to order Ratite. This order is of flightless birds with flat breast bone and it includes emu, ostrich, rhea, cassowary and kiwi. Emus are reared commercially in many parts of the world for their meat, oil, skin and feathers, which are of high economic value. The anatomical and physiological features of these birds appear to be suitable for temperate and tropical climatic conditions. Emu is newly introduced species in India. Although emu farming is considered to be economical, we have to study the behavior of emus to increase the profitability by providing housing, feeding and breeding facilities more or less same as that of in wild condition during their rearing in captivity and we will have to carry out comparative study of behavior in captivity as well as in wild condition.

  5. Current status, surveillance and control of avian flu in domestic and wild bird populations in Bulgaria

    International Nuclear Information System (INIS)

    Avian influenza (AI) is a highly contagious viral disease affecting several species of food producing birds (chickens, turkeys, quails, guinea fowl, etc.), as well as pet birds and wild birds. The AI viruses are divided in two groups based on their ability to cause disease (pathogenicity). Highly pathogenic avian influenza (HPAI) virus spreads rapidly, may cause serious disease and result in high mortality rates (up to 100% within 48 hours). The low pathogenic avian influenza (LPAI) can causes mild disease that may be undetected or no symptoms at all in some species of birds. Since 1997 millions of chicken have been reported to have died due to HPAI H5N1 in countries of South-East Asia. In 2003 AI virus H7N7 affected poultry farms in Netherlands, then penetrated to Belgium and Germany. It had been considered that among human community there were circulating A viruses of 3 subtypes of H type (H1, H2 and H3) and 2 subtypes of N type (N1 and N2). However, for the recent years it has established that AI viruses as a result of mutation have changed their biological features and acquired a capacity of overcoming an interspecies barrier and affecting humans, mostly with lethal outcome. Once domestic birds are infected, avian influenza outbreaks can be difficult to control and often cause major economic impacts for poultry farmers in affected countries, since mortality rates are high and infected fowl generally must be destroyed -- the technical term is 'culled' -- in order to prevent the spread of the disease. Anatidae (ducks, geese and swans) is a group of water birds that is ecologically dependent on wetlands for at least some aspects of their annual cycle. Anatidae species use a wide range of wetlands, from the high arctic tundra, rivers and estuaries, freshwater or saline lakes, and ponds or swamps to coastal lagoons and inter-tidal coastal areas such as mud-flats, bays and the open sea. They also utilize man-made wetlands such as rice fields and other agricultural

    Science.gov (United States)

    Herman, C.M.

    1969-01-01

    Blood protozoa were first reported from wild birds in 1884. Since then numerous surveys throughout the world have demonstrated their presence in a wide variety of hosts and localities with continuing designations of new species. Taxonomic determinations include parasites in the genera Plasmodium, Haemoproteus, Leucocytozoon, Babesia, Lankesterella and Trypanosoma. Transmission of Plasmodium by mosquitoes was demonstrated with a bird parasite before these insects were proven as vectors of human malaria. All the genera under consideration require an insect vector to complete their life-cycles and susceptible vectors have been demonstrated. Most experimental work on the blood protozoa of birds has been carried on with captive birds. An extensive volume of research has been conducted on Plasmodium because of its close similarity to malaria in man. Field studies that would provide information on the epizootiology of occurrence of these parasites in wild populations have been very limited, mainly confined to single blood film surveys. Such data are inadequate to provide an understanding of true prevalence or incidence or of factual knowledge of their impact on the wild population. Mechanisms for procuring such information are available in some cases and can be developed to fit other situations. Isodiagnosis, inoculation of blood from wild birds into susceptible captive hosts, has revealed a prevalence of over 60 % for Plasmodium in situations where microscope examination of single peripheral blood preparations yielded less than 1 %. Culture of bone marrow collected by biopsy demonstrates high prevalence of trypanosomes even when none are evident from microscopic examination of blood. Often preparations of tissues collected at necropsy reveal Leucocytozoon and Lankesterella when examination of peripheral blood gave no indication of infection. Methods developed by bird ringers provide techniques for obtaining repeat examinations of free-living birds that can yield further

  12. Aerodynamics of intermittent bounds in flying birds

    Science.gov (United States)

    Tobalske, Bret W.; Hearn, Jason W. D.; Warrick, Douglas R.

    Flap-bounding is a common flight style in small birds in which flapping phases alternate with flexed-wing bounds. Body lift is predicted to be essential to making this flight style an aerodynamically attractive flight strategy. To elucidate the contributions of the body and tail to lift and drag during the flexed-wing bound phase, we used particle image velocimetry (PIV) and measured properties of the wake of zebra finch (Taeniopygia guttata, N = 5), flying at 6-10 m s- 1 in a variable speed wind tunnel as well as flow around taxidermically prepared specimens (N = 4) mounted on a sting instrumented with force transducers. For the specimens, we varied air velocity from 2 to 12 m s- 1 and body angle from -15∘ to 50∘. The wake of bounding birds and mounted specimens consisted of a pair of counterrotating vortices shed into the wake from the tail, with induced downwash in the sagittal plane and upwash in parasagittal planes lateral to the bird. This wake structure was present even when the tail was entirely removed. We observed good agreement between force measures derived from PIV and force transducers over the range of body angles typically used by zebra finch during forward flight. Body lift:drag (L:D) ratios averaged 1.4 in live birds and varied between 1 and 1.5 in specimens at body angles from 10∘ to 30∘. Peak (L:D) ratio was the same in live birds and specimens (1.5) and was exhibited in specimens at body angles of 15∘ or 20∘, consistent with the lower end of body angles utilized during bounds. Increasing flight velocity in live birds caused a decrease in CL and CD from maximum values of 1.19 and 0.95 during flight at 6 m s- 1 to minimum values of 0.70 and 0.54 during flight at 10 m s- 1. Consistent with delta-wing theory as applied to birds with a graduated-tail shape, trimming the tail to 0 and 50% of normal length reduced L:D ratios and extending tail length to 150% of normal increased L:D ratio. As downward induced velocity is present in the

  14. Towards understanding of birds magnetoreceptor mechanism

    CERN Document Server

    Solovyov, Ilia A

    2007-01-01

    In the present letter we suggest a new theoretical model for a quantitative description of the magnetoreception mechanism in birds. The considered mechanism involves two types of iron minerals (magnetite and maghemite) which were found in subcellular compartments within sensory dendrites of the upper beak of several bird species. The analysis of forces acting between the iron particles shows that the orientation of the external geomagnetic field can significantly change the probability of the mechanosensitive ion channels opening and closing. The performed theoretical analysis shows that the suggested magnetoreceptor system might be a sensitive biological magnetometer providing an essential part of the magnetic map for navigation.

  8. Agro-environmental policies in Germany

    International Nuclear Information System (INIS)

    Agricultural activities always have impacts on the environment. Whereas soil erosion is a minor problem in Germany water pollution due to modern and intensive agriculture is of major concern. At first the paper discusses to what extent agriculture contributes to environmental pollution in Germany, in particular to the pollution of surface waters (as well as hydroelectric power constructions on the Danube) and groundwater by nutrients and pesticides. Agro-environmental policy in Germany is dominated by command-and-control-measures. Hence, in the second section, recent developments of the most important legal and institutional settings concerning water conservation policies are surveyed with special emphasis on the Federal Water Act and the Implementation of the Nitrate Directive into German legislation by the Fertilizer Ordinance. Thirdly, impacts of alternative water conservation policies are investigated using a regionalized agricultural sector model. Information obtained by this model analysis cover the development of N-balances, potential nitrate concentrations in the recharged groundwater, costs potentially effected by this and resulting agricultural incomes on the country level of the former Federal Republic Germany. The last section focuses on programs promoting environmentally sound farming practices, which gained increasing importance in the Common Agricultural Policy of the European Union in the last years. It is argued that this development will also continue in the future. (author)

  11. Macroeconomic trends and reforms in Germany

    Directory of Open Access Journals (Sweden)

    Roberto Sabbatini

    2010-01-01

    Full Text Available This paper traces the main macroeconomic developments in the German economy from national unification. Its performance is compared with that of the rest of the euro area and its largest economies. The study documents as GermanyÕs modest growth in the later 1990s was due to the restrictive impact on domestic demand coming from the deep restructuring and modernization of the production system, followed by sweeping reforms after the turn of the century. Rapid productivity increases and prolonged wage moderation, especially in industry, fuelled a large and mounting current account surplus in Germany, that compares with the deficits registered in most European countries. The study retraces the recent debate on how to correct those imbalances, recalling the arguments for and against the thesis that the countries with a current payments surplus, above all Germany, must also play an active role in fostering the adjustment of the deficit countries. A possible synthesis is proposed, based on an analysis of the formation of national income and the use of resources according to the national accounts system. The implication is that Germany may contribute to the correction of imbalances within the euro area not so much by altering the wage formation mechanism as by creating incentives for domestic investment, hence fostering employment creation, in the service sectors that are currently lagging behind the extraordinary perfomance of a number of core activities in the industry.

    The Asian tiger mosquito (Aedes albopictus) is of great concern to public health authorities due to its vector competence and rapid spread across the globe. In 2015, two large local breeding populations of Ae. albopictus were discovered in southwest Germany. In spring 2016, we were able to demonstrate the first evidence of a successful overwintering in Germany of this originally tropical mosquito species in different research projects. Particularly noteworthy is the successful hatching of diapause eggs of an Italian strain (Calabria), which overwintered successfully in the field in St. Georgen im Schwarzwald (Baden-Wuerttemberg) at 820 m above sea level. Furthermore, within the scope of a larvae monitoring, the first larvae that hatched in the field were detected on the April 09, 2016 in a rain barrel within the Heidelberg population. Our first results show that self-extinction due to an unsuccessful overwintering cannot be assumed for populations of the Asian tiger mosquito which settled in Germany in previous years. The evidence of a successful overwintering of a large number of diapause eggs and the hatching of the first larvae in field conditions opens the control year against Ae. albopictus in southwest Germany.

    Hales, Christy; Ring, Robert

    2016-01-01

    Within seconds after liftoff of the Space Shuttle during mission STS-114, a turkey vulture impacted the vehicle's external tank. The contact caused no apparent damage to the Shuttle, but the incident led NASA to consider the potential consequences of bird strikes during a Shuttle launch. The environment at Kennedy Space Center provides unique bird strike challenges due to the Merritt Island National Wildlife Refuge and the Atlantic Flyway bird migration routes. NASA is currently refining risk assessment estimates for the probability of bird strike to space launch vehicles. This paper presents an approach for analyzing the risks of bird strikes to space launch vehicles and presents an example. The migration routes, types of birds present, altitudes of those birds, exposed area of the launch vehicle, and its capability to withstand impacts affect the risk due to bird strike. A summary of significant risk contributors is discussed.

  1. Research on an infectious disease transmission by flocking birds.

    Science.gov (United States)

    Tang, Mingsheng; Mao, Xinjun; Guessoum, Zahia

    2013-01-01

    The swarm intelligence is becoming a hot topic. The flocking of birds is a natural phenomenon, which is formed and organized without central or external controls for some benefits (e.g., reduction of energy consummation). However, the flocking also has some negative effects on the human, as the infectious disease H7N9 will easily be transmited from the denser flocking birds to the human. Zombie-city model has been proposed to help analyzing and modeling the flocking birds and the artificial society. This paper focuses on the H7N9 virus transmission in the flocking birds and from the flocking birds to the human. And some interesting results have been shown: (1) only some simple rules could result in an emergence such as the flocking; (2) the minimum distance between birds could affect H7N9 virus transmission in the flocking birds and even affect the virus transmissions from the flocking birds to the human.

  2. The outlook for natural gas in Germany

    International Nuclear Information System (INIS)

    In a generally stagnant energy market, gas will be the energy with the highest growth rate in Germany, especially because of its steadily rising shares in the residential and commercial sector. In western Germany there is to be accepted that the demand forecasts, which were raised from one conference to the next, have passed their zenith. Great uncertainty exists as regards the future use of gas for power generation. In the absence of any significant expansion of this market sector, which is considered rather improbable in western Germany, it can be stated that anticipated gas demand up to the year 2005 is already covered by existing import contracts and scheduled domestic production. The picture is completely different in eastern Germany, where a doubling of consumption is quite feasible. To achieve the requisite diversification of supplies, substantial additional imports from western sources will have to be contracted. Russia can and should remain eastern Germany's main supplier in the long run, but Russian deliveries must be placed on a reliable, long-term contractual basis. As far as new gas projects are concerned, deliveries from Norway, to a limited extent from the United Kingdom and above all as part of the new Russian export initiative are under discussion. Generally speaking, transit will be an increasingly significant issue, especially for additional supplies from Russia. The efficiency and reliability of gas marketing companies will become far more important in an environment characterised by growing uncertainties. The reliable customer offering a dependable market outlet will be increasingly sought. With energy prices likely to increase only slightly, the management of uncertainties and the safeguarding of economic driving forces will be the main challenge facing our supply projects. 15 figs

  3. Is Germany a model for managers?

    Science.gov (United States)

    Wever, K S; Allen, C S

    1992-01-01

    Most American managers have a hard time making sense of Germany. The country has a fraction of the resources and less than one-third the population of the United States. Labor costs are substantially higher, paid vacations are at least three times as long, and strong unions are deeply involved at all levels of business, from the local plant to the corporate boardroom. Yet German companies manage to produce internationally competitive products in key manufacturing sectors, making Germany the greatest competitive threat to the United States after Japan. The seemingly paradoxical nature of the German economy typically evokes one of two diametrically opposed responses. The first is to celebrate the German economy as a "model" worth emulating--indeed, as the answer to declining U.S. competitiveness. The alternative, more skeptical response is to question Germany's staying power in a new, more competitive global economy. According to Kirsten Wever and Christopher Allen, the problem with both points of view is that they miss the forest for the trees. Observers are so preoccupied with praising--or blaming--individual components of the German economy that they fail to see the dynamic logic that ties these components together into a coherent system. In their review of recent research on the German business system, Wever and Allen argue that managers can learn an important lesson from Germany. In the global economy, competition isn't just between companies but between entire socioeconomic systems. Germany's ability to design a cohesive economic and social system that adapts continuously to changing requirements goes a long way toward explaining that country's competitive success.

    1988-01-01

    Severe gross and microscopic lesions and other changes were found in adult aquatic birds and in embryos from Kesterson Reservoir (a portion of Kesterson National Wildlife Refuge), Merced County, Calif., during 1984. Adult birds from that area were emaciated, had subacute to extensive chronic hepatic lesions, and had excess fluid and fibrin in the peritoneal cavity. Biochemical changes in their livers included elevated glycogen and non-protein-bound sulfhydryl concentrations and glutathione peroxidase activity but lowered protein, total sulfhydryl, and protein-bound sulfhydryl concentrations. Congenital malformations observed grossly in embryos were often multiple and included anophthalmia, microphthalmia, abnormal beaks, amelia, micromelia, ectrodactyly, and hydrocephaly. Mean concentrations of selenium in livers (94.4 ppm, dry weight) and kidneys (96.6 ppm) of birds collected at the Kesterson ponds were about 10 times those found at a nearby control area (8.3 and 12.2 ppm). We conclude that selenium present in the agricultural drainage water supplied to the Kesterson ponds accumulated in the food chain of aquatic birds to toxic concentrations and caused the lesion and other changes observed.

    2013-01-01

    Pet birds are a not-so-well known veterinarian's clientship fraction. Bought individually or in couples, as families often do (which is a lucrative business for pet shops or local breeders) or traded (sometimes illegally) for their very high genetic or exotic value, these birds, commonly canaries, parakeets or parrots, are regularly sold at high prices. These animals, however, are potential carriers and/or transmitters of zoonotic diseases. Some of them could have an important impact on human health, like chlamydophilosis, salmonellosis or even highly pathogenic avian influenza A H5N1. This review paper, although non exhaustive, aims at enlightening, by the description of several cases of bird-human transmission, the risks encountered by bird owners, including children. Public health consequences will be discussed and emphasis will be made on some vector-borne diseases, known to be emergent or which are underestimated, like those transmitted by the red mite Dermanyssus gallinae. Finally, biosecurity and hygiene, as well as prevention guidelines will be developed and perspectives proposed. PMID:23687940

  17. Calcium, snails, and birds: a case study

    Directory of Open Access Journals (Sweden)

    R. Mänd

    2000-10-01

    Full Text Available Recent studies have shown that wild birds breeding in acidified areas have difficulties with obtaining sufficient calcium for their eggshells, and that the cause of it is the shortage of land snails. Many birds have to search for Ca-rich snail shells on a daily basis during egg production. Molluscs depend on litter calcium, which has decreased due to acidification of the environment. Calcium limitation may be a widespread phenomenon also in non-acidified, naturally Ca-poor areas. The problem is that while in the latter areas the time for development of specific adaptations may have been sufficient, then in acidified areas, on the contrary, calcium shortage is a recent phenomenon. Therefore, since the extent of calcium limitation in non-acidified areas is hard to derive from observational data, experimental approach is needed. We provide experimental evidence that specific calcium deficit does affect reproductive traits also in the birds breeding in naturally base-poor habitats. Our study was conducted in a heterogeneous woodland area in Estonia containing deciduous forest patches as well as base-poor pine forest with low snail abundance. Ca supplementation, using snail shell and chicken eggshell fragments, was carried out for pied flycatchers and great tits. Extra calcium affected positively several reproductive traits like egg volume and eggshell thickness, start of breeding, and fledglings’ parameters. The negative relationship between calcium availability and lay-date suggests that birds adjust their breeding tactics to conditions of Ca deficiency, for example, by postponing laying.

  3. Low ecological disparity in Early Cretaceous birds.

    Mitchell, Jonathan S; Makovicky, Peter J

    2014-07-22

    Ecological divergence is thought to be coupled with evolutionary radiations, yet the strength of this coupling is unclear. When birds diversified ecologically has received much less attention than their hotly debated crown divergence time. Here, we quantify how accurately skeletal morphology can predict ecology in living and extinct birds, and show that the earliest known assemblage of birds (=pygostylians) from the Jehol Biota (≈125 Ma) was substantially impoverished ecologically. The Jehol avifauna has few representatives of highly preservable ecomorphs (e.g. aquatic forms) and a notable lack of ecomorphological overlap with the pterosaur assemblage (e.g. no large or aerially foraging pygostylians). Comparisons of the Jehol functional diversity with modern and subfossil avian assemblages show that taphonomic bias alone cannot explain the ecomorphological impoverishment. However, evolutionary simulations suggest that the constrained ecological diversity of the Early Cretaceous pygostylians is consistent with what is expected from a relatively young radiation. Regardless of the proximate biological explanation, the anomalously low functional diversity of the Jehol birds is evidence both for ecological vacancies in Cretaceous ecosystems, which were subsequently filled by the radiation of crown Aves, and for discordance between taxonomic richness and ecological diversity in the best-known Mesozoic ecosystem.

    2014-05-23

    The evolution of the ratite birds has been widely attributed to vicariant speciation, driven by the Cretaceous breakup of the supercontinent Gondwana. The early isolation of Africa and Madagascar implies that the ostrich and extinct Madagascan elephant birds (Aepyornithidae) should be the oldest ratite lineages. We sequenced the mitochondrial genomes of two elephant birds and performed phylogenetic analyses, which revealed that these birds are the closest relatives of the New Zealand kiwi and are distant from the basal ratite lineage of ostriches. This unexpected result strongly contradicts continental vicariance and instead supports flighted dispersal in all major ratite lineages. We suggest that convergence toward gigantism and flightlessness was facilitated by early Tertiary expansion into the diurnal herbivory niche after the extinction of the dinosaurs. PMID:24855267

  5. Hmong of Germany: Preliminary Report on the Resettlement of Lao Hmong Refugees in Germany

    Full Text Available This paper briefly describes the resettlement of Lao Hmong refugees in Germany since the fall of Laos in 1975. Data for this paper were collected during my two visits to the Hmong community of Gammertingen in southern Germany. Although, it has been known that there are Lao Hmong refugees living in Germany, literature about their resettlement in academic journals and the western media has been nonexistent. Therefore, information about their population, social, educational and economic status has not been available. While serving in the U.S. Army, I was fortunate to be stationed in Germany and had several opportunities to visits and interact with this isolate Hmong community. Therefore, I would like to share what little information I have gathered about this forgotten Hmong community. This paper provides a preliminary report on the resettlement process, population, social, educational and economic status of this community. Data were collected primarily through informal direct interviews with the head of household from four families of the original five families that resettled in Germany. As of the writing of this paper, there is no other known Hmong community in Germany other than this Gammertingen Hmong community.

    2012-01-01

    Flight is one of the energetically most costly activities in the animal kingdom, suggesting that natural selection should work to optimize flight performance. The similar size and flight speed of birds and bats may therefore suggest convergent aerodynamic performance; alternatively, flight performance could be restricted by phylogenetic constraints. We test which of these scenarios fit to two measures of aerodynamic flight efficiency in two passerine bird species and two New World leaf-nosed ...

    2013-01-01

    Full Text Available The national status of Nepal birds was determined using the IUCN Red List criteria and following IUCN regional guidelines. Records of all species identified as potentially at high risk were extracted from all relevant references in a comprehensive, up-to-date Nepal bird bibliography. In addition, numerous previously undocumented records were obtained from observers in Nepal. The initial list of potentially threatened species was revised as records were accumulated. Literature reviews were made of current pressures on Nepal birds, responses to these pressures and recommendations for the future. Finally a comprehensive summary table was compiled for all nationally threatened species, including their world distribution, global threat status, national threat status, occurrence, habitat, main altitudinal range, population, key threats, research needs, and key conservation interventions needed. In 2010, 149 bird species (17% of the total recorded of Nepal birds were considered nationally threatened: 53 Critically Endangered species, 48 Endangered and 47 Vulnerable. Near Threatened species were not assessed due to lack of time available for the necessary research. An additional 16 species were considered threatened in 2010 compared with 2004; no species assessed as threatened in 2004 was considered non-threatened in 2010. When habitat types are considered wetland species are the most threatened (35% of the total wetland species, followed by grassland species (23%. When altitudinal preferences are considered lowland species are the most threatened (36% of all lowland species, followed by species only occurring in the middle hills (17%. Human activities leading to habitat loss and damage are the major threats, with agriculture the root cause; hunting and trapping are other important threats. Effective responses for conservation include Nepal protected areas network, community forestry, designation of Ramsar sites, National Wetland Policy implementation

  18. Aquatic Food Plants and their Consumer Birds at Sandi Bird Sanctuary, Hardoi, Northern India

    2013-07-01

    Full Text Available One of the Bird Sanctuaries of Uttar Pradesh, Sandi, was selected for studying some ecological aspects like, aquatic food plants, their food calendar and dependent birds of migratory as well as resident origin. The study site is considered as an ideal wetland. This is located at 27o15’ N and 79o55’ E. Thirty four food plant species were identified to be eaten by 16 birds.These plants were the species of Alloteropsis, Arundo, Azolla, Ceratophyllum, Chloris, Commelina, Cyperus, Echinochloa, Eichhornia, Eleocharis, Hydrilla, Ipomoea, Jussiaea, Lemna, Najas, Nelumbo, Nymphea, Nymphoides, Oryza, Pistia, Polygonum, Potamogeton, Scirpus, Spirodela, Trapa, Typha, Vallisneria, and Wolffia. Common consumer birds eating plant parts were Coot, Pochards, Teal, Wigeon, Gadwal, Gargany, Goose, Whistling-duck, Mallard, Pintail, Shoveler, and Swamphen. These are primarily the migratory birds except Coot, Whistling-duck and Swamphen. Spot-billed Duck, and Indian Moorhen were occasionally seen eating submerged hydrophytes and filamentous slimy green algae. On the basis of multi-strata growth of plants in the Sanctuary a wetland profile was prepared. Food calendar i.e., availability of palatable parts of plants during different months was recorded. Information collected in the study could be used for habitat management, especially the weed removal and ensuring food sustainability for the vegetarian birds.

    2016-01-01

    With the increase of mixed species exhibits in zoos, targeting enrichment for individual species may be problematic. Often, mammals may be the primary targets of enrichment, yet other species that share their environment (such as birds) will unavoidably be exposed to the enrichment as well. The purpose of this study was to determine if (1) auditory stimuli designed for enrichment of primates influenced the behavior of captive birds in the zoo setting, and (2) if the specific type of auditory enrichment impacted bird behavior. Three different African bird species were observed at the Buffalo Zoo during exposure to natural sounds, classical music and rock music. The results revealed that the average frequency of flying in all three bird species increased with naturalistic sounds and decreased with rock music (F = 7.63, df = 3,6, P = 0.018); vocalizations for two of the three species (Superb Starlings and Mousebirds) increased (F = 18.61, df = 2,6, P = 0.0027) in response to all auditory stimuli, however one species (Lady Ross's Turacos) increased frequency of duetting only in response to rock music (X(2) = 18.5, df = 2, P influence behavior in non-target species as well, in this case leading to increased activity by birds.

    Full Text Available Germany's socio-economic model, the "social market economy", was established in West Germany after World War II and extended to the unified Germany in 1990. During a prolonged recession after the adoption of the Euro in 1998, major reforms (Agenda 2010 were introduced which many consider as the key of Germany's recent success. The reforms had mixed results: employment increased but has consisted to a large extent of precarious low-wage jobs. Growth depended on export surpluses based on an internal real devaluation (low unit labour costs which make Germany vulnerable to global recessions as in 2009. Overall inequality increased substantially.

    2016-01-01

    First the discussion of Kohut's new ideas in the United States is sketched as a background. The response to these ideas was divided: on the one hand they were hailed as important innovations of psychoanalytic theory, and a circle of colleagues formed around their author; on the other hand they were violently rejected, and old friends distanced themselves from him. In Germany Kuhut's ideas were initially well received. His visits, lectures and supervisions resulted in a lively exchange and a number of friendships. When the differences between Kohutian and classical theory became evident this led increasingly to disillusionment and retreat. De-emphasizing drive and ego psychology had considerable consequences for psychoanalytic technique as well as for the analyst's Menschenbild, his relationship to the patient and his critical self-reflection. In Germany, too, a circle of colleagues emerged, following and elaborating the ideas of Kohut. PMID:27281981

  5. Safe Operation of Research Reactors in Germany

    International Nuclear Information System (INIS)

    In Germany, experience was gained in the field of safe operation of research reactors during the last five decades. In this time, in total 46 research reactors were built and operated safely. Concerning the design, there is, or has been, a very broad range of different types of research reactors. The variety of facilities includes large pool or tank reactors with a thermal power of several tens of megawatt as well as small educational reactors with a negligible thermal power and critical assemblies. At present, 8 research reactors are still in operation. The other facilities are permanently shutdown, in decommissioning or have already been dismantled completely and released from regulatory control. In this paper, four selected facilities still being operated are presented as examples for safe operation of research reactors in Germany, including especially a description of the safety reviews and safety upgrades for the older facilities.

  6. Germany: National approach to ageing management

    International Nuclear Information System (INIS)

    The Fukushima Accidents have led to fundamental changes in the usage of nuclear power in Germany. On August 1, 2011, an amendment of the German Atomic Energy Act came into force. It consists basically of an accelerated step-by-step phase-out until 2022. Eight older NPPs were shut down immediately. The remaining NPP will be stepwise shut down so that the last one will stop commercial operation at the end of 2022. Against this background, long-term operation is not an issue anymore in Germany. However, for the NPPs in operation it is necessary to ensure the required quality of safety-related SSCs by an AM process, though the specified operational lifetime is not enlarged. The new nuclear safety standard KTA 1403 was established and issued in December 2010 specifies the German Reactor Safety Commission’s recommendation on AM of 2004 and is also considered to fulfil the related IAEA guidelines and WENRA safety levels

  7. Year 2 of Germany's Energy Transition

    International Nuclear Information System (INIS)

    After a decade characterised by the take-off of renewable energies, Germany decided in 2010 to make them the top priority. At the same time, it decided to make exemplary efforts in terms of energy efficiency and the reduction of greenhouse gases. The audacious nature of this policy was strengthened by the 'turn' taken in 2011 to give up nuclear energy in the wake of the Fukushima accident. Given the initial results for 2012, Germany seems to be on target for reaching its national objective, of 18% renewable energy within total consumption by 2020. Germany is also well placed to reduce its planned cut in electricity consumption of 10%. The country will also meet its commitments, both international and European, concerning greenhouse gas emissions. In contrast, recent trends suggest it will be increasingly difficult for Germany to meet its own, domestic goal of cutting emissions by 40%, by 2020. Furthermore, it is hard to see how Germany will be able to bring down total energy consumption by 20% by 2020 (from 2008 levels), or increase the share of renewables in electricity production above 35%. Success with this latter objective is largely dependent on reinforcing networks, both for transmission over long distances and for local distribution. It is not sure that the delays accumulated in both areas will be made up for by 2020, despite the rapid legislative adjustments that have already been made. By favouring intermittent energy sources - wind and solar power - Germany also faces problems of managing frequent production fluctuations. The long term solution to this lies in storing electricity. However, despite the considerable efforts in research and development, the technologies necessary for this will doubtless not be available on a large scale before the end of the present decade. These efforts could nevertheless provide German industry with interesting advantages in sectors of high potential, such as electric vehicles. Measures to promote renewable energies are

  8. The future of nuclear power in Germany

    International Nuclear Information System (INIS)

    The future of nuclear power in Germany is not only a matter of technology, economy and ecology but, above all, a matter of political leadership, the quality of interaction of all groups of society, the need to take ideology out of politico-economico-technical matters, and of firmly standing up for a style of democracy in which majorities, not minorities, decide. The power economy is agreed that nuclear power is indispensable in a powerful electricity supply scheme. These should be the criteria to be met by an energy consensus: No nuclear plants should be sacrificed by being shut down before the end of their technical and economic service life; spent fuel and waste management in Germany should be secured with sufficient interim storage and repository storage capacities.

    2005-07-01

    Epidemiologic trends of human leptospirosis in Germany were investigated by analyzing national surveillance data from 1962 to 2003 and by conducting a questionnaire-based survey from 1997 to 2000. After a steady decrease of leptospirosis incidence from 1962 to 1997, surveillance data indicate an increase in disease incidence to 0.06 per 100,000 (1998-2003). Of 102 laboratory-confirmed cases in humans from 1997 to 2000, 30% were related to occupational exposures. Recreational exposures were reported in 30% (including traveling abroad in 16%), whereas residential exposure accounted for 37% of the cases. Direct contact with animals, mostly rats and dogs, was observed in 31% of the cases. We conclude that recent changes in transmission patterns of leptospirosis, partially caused by an expanding rat population and the resurgence of canine leptospirosis, may facilitate the spread of the disease in temperate countries like Germany. Preventive measures should be adapted to the changing epidemiology of leptospirosis. PMID:16022779

  10. Aquifer thermal energy stores in Germany

    International Nuclear Information System (INIS)

    This paper describes the state of essential demonstration projects of heat and cold storage in aquifers in Germany. Into the energy supply system of the buildings of the German Parliament in Berlin, there are integrated both a deep brine-bearing aquifer for the seasonal storage of waste heat from power and heat cogeneration and a shallow-freshwater bearing aquifer for cold storage. In Neubrandenburg, a geothermal heating plant which uses a 1.200 m deep aquifer is being retrofitted into an aquifer heat storage system which can be charged with the waste heat from a gas and steam cogeneration plant. The first centralised solar heating plant including an aquifer thermal energy store in Germany was constructed in Rostock. Solar collectors with a total area of 1000m2 serve for the heating of a complex of buildings with 108 flats. A shallow freshwater-bearing aquifer is used for thermal energy storage. (Authors)

  11. Quantification of bird-to-bird and bird-to-human infections during 2013 novel H7N9 avian influenza outbreak in China.

    Directory of Open Access Journals (Sweden)

    Ying-Hen Hsieh

    Full Text Available From February to May, 2013, 132 human avian influenza H7N9 cases were identified in China resulting in 37 deaths. We developed a novel, simple and effective compartmental modeling framework for transmissions among (wild and domestic birds as well as from birds to human, to infer important epidemiological quantifiers, such as basic reproduction number for bird epidemic, bird-to-human infection rate and turning points of the epidemics, for the epidemic via human H7N9 case onset data and to acquire useful information regarding the bird-to-human transmission dynamics. Estimated basic reproduction number for infections among birds is 4.10 and the mean daily number of human infections per infected bird is 3.16*10-5 [3.08*10-5, 3.23*10-5]. The turning point of 2013 H7N9 epidemic is pinpointed at April 16 for bird infections and at April 9 for bird-to-human transmissions. Our result reveals very low level of bird-to-human infections, thus indicating minimal risk of widespread bird-to-human infections of H7N9 virus during the outbreak. Moreover, the turning point of the human epidemic, pinpointed at shortly after the implementation of full-scale control and intervention measures initiated in early April, further highlights the impact of timely actions on ending the outbreak. This is the first study where both the bird and human components of an avian influenza epidemic can be quantified using only the human case data.

A total of 105 species of birds belonging to 12 orders, 35 families and 77 genera were recorded. Out of 105 species, 51 (48.6% were non-passerine and 54 (51.4% passerine, 33 (31.4% migratory and 72 (68.6% resident. Of the non-passerine birds, 15 (29.4% were migratory and 36 (70.6% were resident, while, among the passerines 18 (33.3% were migratory and 36 (66.7% were resident. Of the total (105 species 14 (13.3% were found to be very common, 30 (28.6% common, 25 (23.8% fairly common and 36 (34.3% were rare or few. Out of 105 species, 30 (28.6% were aquatic and semiaquatic birds and 75 (71.4% were terrestrial. Among 105 species, 52 (49.5% were widely distributed in Kurigram, 31 (29.5% restricted only to the northern side, five (4.8% to the central side, eight (7.6% to the southern side, and nine (8.6% species were common in two or three parts of the study area.

  13. Radionuclides and the birds at Ravenglass.

    1991-01-01

    Since 1983, concern has been expressed about the apparent decline in numbers of birds in the Ravenglass estuary in west Cumbria, particularly of the black-headed gull colony on the Drigg dunes, and suggestions have been made that this decline might be due to excessive radiation in the birds' food and their general environment. Twelve species of marine invertebrates from Ravenglass, most of them known to be important foods for birds, were analysed, and further samples were taken from sites along the west Cumbrian coast. None of these samples showed excessive contamination with any of the radionuclides analysed. Analysis of a sample of bird carcasses from the areas showed oystercatchers (Haematopus ostralegus) and shelduck (Tadorna tadorna) to have some of the highest concentrations of (137)Cs in their tissues; yet their breeding success and populations were not affected. Black-headed gulls, on the other hand, were found to be feeding mainly inland, and were the least contaminated with radionuclides of all the birds at Ravenglass, yet this species and its breeding success were in decline. Calculations of the total dose equivalent rate to the whole body of the most contaminated black-headed gull amounted to 9.8 x 10(-4) mSvh(-1) (approximately equal to 8.4 x 10(-4) mGy h(-1), whole body absorbed dose rate), and the background exposure dose was of the order of 8.3 x 10(-4) mGy h(-1). As a minimum chronic dose of 1000 mGy day(-1) has been found necessary to retard growth of nestling birds, and 9600 mGy over 20 days of incubation to cause the death of 50% of embryos in black-headed gulls' eggs, the concentrations of radionuclides in the foods, body tissues and general environment were at least three orders of magnitude too low to have had any effect. The more likely cause of the desertion of the gullery was the combination of an uncontrolled fox population, the severest outbreak of myxomatosis amongst the rabbits since 1954 and the driest May-July period on record, all

    This paper analyses the role of bank lending in the monetary transmission process in Germany. We follow a sectoral approach by distinguishing corporate lending and household lending. We find that banks respond to a monetary contraction by adjusting their securities holdings, rather than reducing their loans portfolio. Most lending categories even show an increase following a monetary tightening. The main implication of our results is that a bank lending channel is not an important transmissio...

    In the tax policy debate, differentiation of value-added taxes is often justified by distributional concerns. Our quantitative analysis for Germany indicates that such concerns are misplaced. We find that the abolition of VAT differentiation has only negligible redistributive effects. Instead, reduced VAT are found to act as industry-specific subsidies. Whereas the overall welfare effects of pure VAT reforms are very small, a revenue-neutral introduction of a harmonised VAT combined with redu...

    2010-07-01

    This PowerPoint presentation described some of the inventories and instrumentation available for monitoring winged fauna in and around wind farms. In addition to visual observations, bird calls and songs can be recorded to determine the amount and different types of birds located at wind farm sites. Radio-telemetry devices are also used to evaluate bird activities, and nest searches are conducted to determine the amount of eggs or young birds that will soon add to the bird population. Between 90 and 100 percent of birds and bats migrate at night. Acoustic radar, Doppler radar, and maritime surveillance radar instruments are used to monitor night-time activities in wind farm locations. Doppler radar is also used to detect bird and bat migration corridors. Screen-shots of various radar interfaces were presented. tabs., figs.

    2012-01-01

    Full Text Available This paper presents an analysis of the semantics of bird denominations in Mari: an attempt is made to define the factors, or features, motivating bird denominations. Analysis is based on a set of words of inner origin that are part of the corpus of bird names compiled by the author. The results show that the ornithonomy of the Mari language, created over centuries, constitutes a well-shaped system. It reflects a variety of features associated with the appearance, way of life of the birds, sounds they produce, etc. Many bird terms reflect features of appearance. It is interesting to note that the names of birds not seen for some reason may relate to the characteristics of the birds’ voices. In some cases, terms are based on a combination of features.In dialects, different names for same birds may occur, as observed in the sources.

  16. Germany sees profits collapse as doldrums persist

    International Nuclear Information System (INIS)

    Traditionally the strongman of Europe, Germany's chemical sector had a miserable time in 1992, as profits skidded 30%. Further declines in production and sales for the first half of 1993 are predicted by industry association VCI (Frankfurt). Output, usually spurred after the summer break, dropped drastically in the fourth quarter. Developments are alarming, says Wolfgang Hilger, president of the VCI and chairman of Hoechst (Frankfurt). Production in the 11 western states rose 1% in 1992, but chemical industry sales fell. In the second half of the year, the high value of the Germany mark - against the US dollar, sterling, lira, and peseta - compounded difficulties already experienced as a result of overcapacity and lower prices. Hilger says overall prices declined 2% last year. Meanwhile, costs for labor and environmental protection continued to increase. VCI figures show a decline in many sectors. In western Germany, organic base chemical production was down 4%, and, while organic chemical production rose 3%, prices were 8% lower, giving unsatisfactory results. Similarly, plastics production was up 0.5% at midyear, but weak prices hurt earnings

  17. Propagation characteristics of thunderstorms in southern Germany

    Hagen, M.; Bartenschlager, B.; Finke, U.

    1998-05-01

    The propagation of thunderstorms in southern Germany was investigated. The thunderstorms were observed by a lightning position system during the summer months of the years 1992 to 1996. On average every second day thunderstorms were observed anywhere in southern Germany. In general thunderstorms approach from westerly and south-westerly directions. The average speed is 13 m/s. No significant relation between the occurrence of thunderstorms and the large scale synoptic pattern described by the Grosswetterlagen (large scale weather pattern) was found. Thunderstorms were observed during almost all Grosswetterlagen. The reduction to 8 weather pattern based on the low-level flow in southern Germany showed that thunderstorms are likely when the flow has westerly directions (43%) or easterly directions (20%). Three distinct groups of different lightning patterns could be identified; stationary, moving thunderstorms and thunderstorm lines. The convective available potential energy (CAPE) and the wind shear were retrieved from the radio soundings from Muenchen and Stuttgart. On average CAPE was 583 J/kg for stationary, 701 J/kg for moving thunderstorms, and 876 J/kg for thunderstorm lines. The average bulk Richardson numbers are 152, 80 and 52 for stationary, moving thunderstorms and thunderstorm lines, respectively. The steering level was found to be at about 3 and 6 km m.s.l. However, it should be noted, that in most cases the soundings do not completely describe the local environment of thunderstorms, since radio soundings are only available twice a day. (orig.)

  18. Transport regulations for radioactive material in Germany

    International Nuclear Information System (INIS)

    The transport of radioactive material in Germany is regulated by the dangerous goods transport regulations and the regulations of the Atomic Energy Act and the Radiation Protection Ordinance. For radioactive material shipments by road, rail, sea and air the modal regulations on the transport of dangerous goods for class 7 of the ADR, RID, ADNR, IMO and ICAO are implemented in Germany and have to be complied with. In parallel with this the Atomic Energy Act requirements and the provisions of the Radiation Protection Ordinance concerning the transport of radioactive material have to be met. They contain provisions regarding the reliability of transport organisations and persons, training of persons involved in transport nuclear liability insurance, physical protection and public interest in addition to the need to fulfil the dangerous goods transport regulations. According to these requirements shipment approvals which are presented in the paper, are necessary for nuclear material, large sources and other radioactive materials. Based on this some practical implications for radioactive material shipments will be discussed as well as some aspects of the future developments. The paper also gives an overview of the responsibilities for approval and inspection of radioactive material shipments in Germany. (author)

    Full Text Available A rather significant proportion of the Societas Europaeas (the European Company, or SE formed to date have had German roots. German corporate law has been enriched by an interesting alternative which meanwhile seems to have gained momentum. This contribution focuses on SEs incorporated by German entrepreneurs and provides an interesting account concerning the use of SEs in Germany in practice, such as Allianz, Fresenius, BASF and Porsche. Has the SE been used to circumvent rigid company law provisions or is it a more flexible and effective tool, perhaps, for company mobility? The practical motives behind setting up this company form are also reflected upon. These include: the facilitation of cross-border mergers; transfer of the registered office; the ‘European’ image; a more flexible form of co-determination in large companies (reduction of the number of supervisory board members; avoidance and freezing of co-determination for medium-sized enterprises; the appeal of the one-tier system and its endangerment by German co-determination; and flat and uniform structures for company groups. The author also briefly discusses some of the problems arising from the formation of SEs in Germany. He ultimately concludes that practice has shown that it is possible to work with the legal regime of the SE in Germany, which adds a new company form to those available in that Member State.

The German Federal government supports the development of geothermal energy in terms of project funding, market incentives and credit offers, as well as a feed-in tariff for geothermal electricity. Although new projects for district heating take on average six years, geothermal energy utilisation is growing rapidly, especially in southern Germany. From 2003 to 2013, the annual production of geothermal district heating stations increased from 60 GWh to 530 GWh. In the same time, the annual power production increased from 0 GWh to 36 GWh. Currently, almost 200 geothermal facilities are in operation or under construction in Germany. A feasibility study including detailed geological site assessment is still essential when planning a new geothermal facility. As part of this assessment, a lot of geological data, hydraulic data, and subsurface temperatures can be retrieved from the geothermal information system GeotIS, which can be accessed online [1].

    2010-06-01

    Full Text Available The expansion of renewable energy production is seen as an appropriate way to mitigate climate change. Renewable energies are not free of negative external effects on humans and the natural environment. We analyzed the conflict between wind power production and bird protection through the example of one of the most sensitive species, the red kite (Milvus milvus in West Saxony, Germany. We investigated a large number of potential land use scenarios, defined by whether or not each potential site contained a wind turbine (WT. Based on meteorological and ornithological data, we evaluated the land use scenarios for their annual energy supply and impact on the red kite. We identified the efficient land use scenarios that maximized energy supply for a given ecological impact. Within the scope of our analysis, the current allocation of WTs in the study region was considered inefficient. The set of efficient scenarios allowed us to draw conclusions on the trade-offs involved. We developed an indicator that measures the severity of the conflict between wind power production and bird protection. Increasing the minimum distance of WTs to settlements beyond the legal requirements in order to minimize the impact on humans further intensifies the conflict. Our results can support planning authorities in their development of long-term regional plans by identifying areas that are most suitable for wind power production from an integrated point of view.

    2007-01-01

    A synoptic review of the discoveries and studies of Chinese Mesozoic birds is provided in this paper.40Ar/39Ar dating of several bird-bearing deposits in the Jehol Group has established a geochronological framework for the study of the early avian radiation.Chinese Mesozoic birds had lasted for at least 11 Ma during about 131 Ma and 120 Ma (Barremian to Aptian)of the middle and late Early Cretaceous,respectively.In order to further evaluate the change of the avian diversity in the Jehol Biota,six new orders and families are erected based on known genera and species,which brings the total number of orders of Chinese Mesozoic birds to 15 and highlights a remarkable radiation ever since the first appearante of birds in the Late Jurassic.Chinese Early Cretaceous birds had experienced a significant differentiation in morphology,flight,diet and habitat.Further examination of the foot of Jeholornis suggests this bird might not have possessed a fully reversed hallux.However,the attachment of metatarsal Ⅰ to the medial side of metatarsal Ⅱ does not preclude trunk climbing,a pre-adaptation for well developed perching life of early birds.Arboreality had proved to be a key adaptation in the origin and early evolution of bird flight,and the adaptation to lakeshore environment had played an equally important role in the origin of omithurine birds and their near-modern flight skill.Many Chinese Early Cretaceous birds had preserved the direct evidence of their diet,showing that the most primitive birds were probably mainly insectivorous and that specialized herbivorous or carnivorous (e.g.,piscivorous)dietary adaptation had appeared only in later advanced forms.The only known Early Cretaceous bird embryo fossil has shown that precocial birds had occurred prior to altricial birds in avian history,and the size of the embryo and other analysis indicate it probably had a short incubation period.Leg feathers probably have a wide range of distribution in early birds

  3. Individuality in bird migration: routes and timing.

    2011-08-23

    The exploration of animal migration has entered a new era with individual-based tracking during multiple years. Here, we investigated repeated migratory journeys of a long-distance migrating bird, the marsh harrier Circus aeruginosus, in order to analyse the variation within and between individuals with respect to routes and timing. We found that there was a stronger individual repeatability in time than in space. Thus, the annual timing of migration varied much less between repeated journeys of the same individual than between different individuals, while there was considerable variation in the routes of the same individual on repeated journeys. The overall contrast in repeatability between time and space was unexpected and may be owing to strong endogenous control of timing, while short-term variation in environmental conditions (weather and habitat) might promote route flexibility. The individual variation in migration routes indicates that the birds navigate mainly by other means than detailed route recapitulation based on landmark recognition. PMID:21307045

    Bacteria of the genus Campylobacter were isolated from 28 Rooks (Corvus frugilegus), 1 Red Kite (Milvus milvus), 1 Lapwing (Vanellus vanellus), 1 Coot (Fulica atra), 1 Common Moorhen (Gallinula chloropus) and 1 Northern Mallard (Anas platyrhynchos). Altogether, C. jejuni biovar 1, was isolated 19x, C. jejuni biovar 2 8x and C. coli 5x. Among C. jejuni biovar 1 and 2 there were 5 isolates tolerating a content of 1.5% NaCl in the medium. H2S proof of 3 C. jejuni biovar 2 and 1 C. coli isolates resulted positive or negative dependent on incubation time of the used bacterial inoculum. Concerning Rooks the findings indicate that nestlings are more often infected with campylobacters than older birds. Only 1 campylobacter isolate could be recovered from altogether 54 birds of prey although 16 Buzzards (Buteo buteo) were investigated as nestlings. PMID:2930449

  5. Energy R and D in Germany; TOPICAL

    International Nuclear Information System (INIS)

    Germany's total national (i.e., combined public and private sector) funding for R and D stood at$42 billion in 1997. The private sector accounted for nearly 62% ($24 billion) of the total, while the public sector accounted for approximately 38%. Since the late 1970s, when the public and private sectors each funded roughly half of Germany's R and D, the private sector has steadily assumed a larger and larger role as the dominant supporter of R and D activity, while overall government funding has remained essentially flat for much of the past two decades. In addition to declining relative to private R and D expenditures, public R and D expenditures in Germany declined by 4% in real terms between 1991 and 1997, to approximately$15 billion. The reduction in R and D investments in the public sector can be attributed in large part to the financial challenges associated with German reunification and related shifts in social priorities including efforts to address high unemployment and to rebuild basic infrastructure in the eastern states. R and D expenditures have also declined as a percentage of the total public budget, from a peak of 3.4% in 1985 to 2.7% in 1996. Energy R and D has been the hardest hit of all major socioeconomic areas of R and D expenditure funded by the German government. Between 1981 and 1997, public energy R and D fell from approximately$1.6 billion to$400 million--a 75% real decline. The$850 million reduction in Germany's fission R and D budget (which constituted two-thirds of government R and D investment in 1985) explains some 90% of the funding decline. Negative public perceptions regarding the safety and environmental impacts of nuclear energy have reduced nuclear power's viability as a long-term energy option for Germany. Discussions of a complete nuclear phaseout are now under way. At the same time, the German government has slashed its investments in fossil energy R and D by more than 90%.

    Flocking is a typical example of emergent collective behavior, where interactions between individuals produce collective patterns on the large scale. Here we show how a quantitative microscopic theory for directional ordering in a flock can be derived directly from field data. We construct the minimally structured (maximum entropy) model consistent with experimental correlations in large flocks of starlings. The maximum entropy model shows that local, pairwise interactions between birds are s...

    Synchronous arrival of pairs of migratory birds at their breeding grounds is important for maintaining pair bonds and is achieved by pairs that remain together all year round. Here we show that arrival is also synchronized in paired individuals of a migratory shorebird, the black-tailed godwit (Limosa limosa islandica), even though they winter hundreds of kilometres apart and do not migrate together. The mechanisms required to achieve this synchrony and prevent 'divorce' illustrate the complexity of migratory systems. PMID:15470417

  13. Hovering and intermittent flight in birds

    International Nuclear Information System (INIS)

    Two styles of bird locomotion, hovering and intermittent flight, have great potential to inform future development of autonomous flying vehicles. Hummingbirds are the smallest flying vertebrates, and they are the only birds that can sustain hovering. Their ability to hover is due to their small size, high wingbeat frequency, relatively large margin of mass-specific power available for flight and a suite of anatomical features that include proportionally massive major flight muscles (pectoralis and supracoracoideus) and wing anatomy that enables them to leave their wings extended yet turned over (supinated) during upstroke so that they can generate lift to support their weight. Hummingbirds generate three times more lift during downstroke compared with upstroke, with the disparity due to wing twist during upstroke. Much like insects, hummingbirds exploit unsteady mechanisms during hovering including delayed stall during wing translation that is manifest as a leading-edge vortex (LEV) on the wing and rotational circulation at the end of each half stroke. Intermittent flight is common in small- and medium-sized birds and consists of pauses during which the wings are flexed (bound) or extended (glide). Flap-bounding appears to be an energy-saving style when flying relatively fast, with the production of lift by the body and tail critical to this saving. Flap-gliding is thought to be less costly than continuous flapping during flight at most speeds. Some species are known to shift from flap-gliding at slow speeds to flap-bounding at fast speeds, but there is an upper size limit for the ability to bound (∼0.3 kg) and small birds with rounded wings do not use intermittent glides.

  15. Birds and Dutch elm disease control

    DeWitt, J.B.

    1958-01-01

    Brief, factual review of information on effect of DDT and other insecticides on birds. One program for control of elm disease caused 22% decrease in number of adult birds and 56% mortality of nestlings. Quail fed 3 oz. of DDT per ton of food had 16% reduction in young hatched and 500% increase in defective chicks. Quail fed same dosage during winter and breeding seasons had 30% decrease in fertile eggs and 800% increase in defective chicks. More than 90% of their chicks died in first 6 weeks although fed no insecticide. Almost equally bad results came from feeding Pheasants diets with about 1 oz. DDT per ton. Other common insecticides (chlorinated hydrocarbons) also caused lowered chick survival and higher percentages of crippled chicks. From field data we know that 2 lbs. DDT/acre can affect birds and has even worse effects on cold-blooded animals. Efforts to control elm disease have left as much as 196 lbs. DDT/acre in top 3 inches of soil. Earthworms concentrate DDT in their tissues. Thus the treated areas can be traps for birds and other animals. What can be done? 1) In control of elm disease, use minimum effective amount of insecticide; mist blowers use less than sprayers. 2) Avoid applications during migration and nesting seasons. It has been reported that adequate control can be obtained with dormant sprays and that foliar applications may not be required. Tables of this paper show effects of DDT on reproduction of Quail, relative toxicity to quail of 8 insecticides, and amounts of 7 insecticides required to cause 40% or more decrease in Quail reproduction. These comparisons demonstrate that Aldrin, Endrin, and Dieldrin are 20 to 200 times as toxic as DDT and that Heptachlor and Chlordane are only slightly less toxic than Dieldrin. Methoxychlor and Strobane are less toxic to Quail than is DDT.

  17. Spring Bird Migration Phenology in Eilat, Israel

    Reuven Yosef

    2009-12-01

    Full Text Available Analysis of the mean date of first captures and median arrival dates of spring migration for 34 species of birds at Eilat, Israel, revealed that the earlier a species migrates through Eilat, the greater is the inter-annual variation in the total time of its passage. Birds arrive during spring migration in Eilat in four structured and independent waves. The annual fluctuation in the initial arrival dates (initial capture dates and median dates (median date of all captures, not including recaptures, did not depend on the length of the migratory route. This implies that migrants crossing the Sahara desert depart from their winter quarters on different Julian days in different years. We suggest that negative correlations between the median date of the spring migration of early and late migrants depends upon the easterly (Hamsin wind period. Moreover, we believe that the phenology of all birds during spring migration in Eilat is possibly also determined by external factors such as weather conditions on the African continent or global climatic processes in the Northern hemisphere. Orphean Warblers (Sylvia hortensis show a strong positive correlation (rs=-0.502 of initial capture date with calendar years, whereas other species such as Barred Warbler (S. nisoria; rs = -0.391 and Spotted Flycatcher (Muscicapa striata; rs = -0.398 display an insignificant trend. The Dead Sea Sparrow (Passer moabiticus and Red-Backed Shrike (Lanius collurio are positively correlated regarding initial arrival date and medians of spring migration.

    LiteBIRD is a next-generation satellite mission to measure the polarization of the cosmic microwave background (CMB) radiation. On large angular scales the B-mode polarization of the CMB carries the imprint of primordial gravitational waves, and its precise measurement would provide a powerful probe of the epoch of inflation. The goal of LiteBIRD is to achieve a measurement of the characterizing tensor to scalar ratio $r$ to an uncertainty of $\\delta r=0.001$. In order to achieve this goal we will employ a kilo-pixel superconducting detector array on a cryogenically cooled sub-Kelvin focal plane with an optical system at a temperature of 4~K. We are currently considering two detector array options; transition edge sensor (TES) bolometers and microwave kinetic inductance detectors (MKID). In this paper we give an overview of LiteBIRD and describe a TES-based polarimeter designed to achieve the target sensitivity of 2~$\\mu$K$\\cdot$arcmin over the frequency range 50 to 320~GHz.

  19. Metal-related oxidative stress in birds

    International Nuclear Information System (INIS)

    Metals can cause oxidative stress by increasing the formation of reactive oxygen species (ROS), which render antioxidants incapable of defence against growing amounts of free radicals. Metal toxicity is related to their oxidative state and reactivity with other compounds. Our aim is to review the mechanisms on how metals cause oxidative stress and what is known about metal-induced oxidative stress in wildlife. Taking birds as model organisms, we summarize the mechanisms responsible for antioxidant depletion and give a view of how to detect metal-induced oxidative stress in birds by using different biomarkers. The mechanisms producing the harmful effects of oxidative stress are complex with different biomolecular mechanisms associated with ecotoxicological and ecological aspects. The majority of the studies concerning metals and ROS related to oxidative stress have focused on the biomolecular level, but little is known about the effects at the cellular level or at the level of individuals or populations. - Free-living birds can be used as effective indicators of metal-induced oxidative stress.

  20. Comparative power curves in bird flight.

    2003-01-23

    The relationship between mechanical power output and forward velocity in bird flight is controversial, bearing on the comparative physiology and ecology of locomotion. Applied to flying birds, aerodynamic theory predicts that mechanical power should vary as a function of forward velocity in a U-shaped curve. The only empirical test of this theory, using the black-billed magpie (Pica pica), suggests that the mechanical power curve is relatively flat over intermediate velocities. Here, by integrating in vivo measurements of pectoralis force and length change with quasi-steady aerodynamic models developed using data on wing and body movement, we present mechanical power curves for cockatiels (Nymphicus hollandicus) and ringed turtle-doves (Streptopelia risoria). In contrast to the curve reported for magpies, the power curve for cockatiels is acutely concave, whereas that for doves is intermediate in shape and shows higher mass-specific power output at most speeds. We also find that wing-beat frequency and mechanical power output do not necessarily share minima in flying birds. Thus, aspects of morphology, wing kinematics and overall style of flight can greatly affect the magnitude and shape of a species' power curve. PMID:12540899

    All birds construct nests in which to lay eggs and/or raise offspring. Traditionally, it was thought that natural selection and the requirement to minimize the risk of predation determined the design of completed nests. However, it is becoming increasingly apparent that sexual selection also influences nest design. This is an important development as while species such as bowerbirds build structures that are extended phenotypic signals whose sole purpose is to attract a mate, nests contain eggs and/or offspring, thereby suggesting a direct trade-off between the conflicting requirements of natural and sexual selection. Nest design also varies adaptively in order to both minimize the detrimental effects of parasites and to create a suitable microclimate for parents and developing offspring in relation to predictable variation in environmental conditions. Our understanding of the design and function of birds' nests has increased considerably in recent years, and the evidence suggests that nests have four nonmutually exclusive functions. Consequently, we conclude that the design of birds' nests is far more sophisticated than previously realized and that nests are multifunctional structures that have important fitness consequences for the builder/s.

    The Chinese Lower Cretaceous Jehol Group is the second oldest fossil bird-bearing deposit, only surpassed by Archaeopteryx from the German Upper Jurassic Solnhofen Limestones. Here we report a new bird, Chongmingia zhengi gen. et sp. nov., from the Jehol Biota. Phylogenetic analyses indicate that Chongmingia zhengi is basal to the dominant Mesozoic avian clades Enantiornithes and Ornithuromorpha, and represents a new basal avialan lineage. This new discovery adds to our knowledge regarding the phylogenetic differentiation and morphological diversity in early avian evolution. The furcula of Chongmingia is rigid (reducing its efficiency), consequently requiring more power for flight. However, the elongated forelimb and the large deltopectoral crest on the humerus might indicate that the power was available. The unique combination of features present in this species demonstrates that numerous evolutionary experimentations took place in the early evolution of powered flight. The occurrence of gastroliths further confirms that herbivory was common among basal birds. The Jehol birds faced competition with pterosaurs, and occupied sympatric habitats with non-avian theropods, some of which consumed birds. Thus, avialan herbivory may have reduced ecological competition from carnivorous close relatives and other volant vertebrates early in their evolutionary history. PMID:26806355

    Full Text Available Through interviews, workshops, conferences and sociocultural meeting, is carried out the linking of three communities from the high area of Gran Piedra to the studies and counts of migratory raptors birds developed in the east of Cuba. These small communities are near to one of the two points of count of migratory raptors of the region. During the interviews we could verify that some residents possessed basic knowledge on the raptors birds, but didn't know about the migration of these birds. 100 % of the interviewees coincided in that the main local problematic is the loss of birds of pen due to the attack of raptors, specifically the endemic Cuban threatened Accipitter gundlachi. The workshops were able to create spaces of exchange and reflection about the importance of the raptor’s conservation in the region. This linkage of cooperation and increasing awareness, allow an approaching between the communitarians and the researchers and volunteers that work in the counts of raptor birds in Cuba and the feedback of the scientific knowledge with the popular knowledge.

    Full Text Available Multi-species heronry at Soor Sarovar Bird Sanctuary, Agra was studied for some breeding and ecological aspects. This is an established heronry in semi-arid region with less than 600 mm rainfall and temperature range of 2oC to 48oC. Two near threatened (Black-headed Ibis and Darter and twelve least concerned species nested in colony during late summer and rainy season. They were categorized as the early arrivers (Black-crowned Night Heron, Little Egret, Cattle Egret, Darter and Grey Heron, late arrivers (Intermediate Egret, Indian Pond Heron, Great Egret, Black-headed Ibis, Purple Heron and Asian Openbill and very late arrivers (Eurasian Spoonbill, Little Cormorant and Indian Cormorant. Total Nest occupancy at a time followed the rainfall pattern of the locality. Nest occupancy calendar was recorded in the form of pre-egg laying, egg laying and chick rearing dates for all the species. Nesting height-bird size hypothesis was checked as mixed results as the stratum specific birds proved the hypothesis right, while stratum interface birds suggested relook of the hypothesis. Heronry threat, disturbance behavior of the birds and disturbance distance were recorded. Buffer establishment and heronry protection measures are recommended for conservation of the source population. The breeding phenology data could be used as baseline as indicator tool for climate change impact.

    From 27 September to 14 December 1978, MBO observers participated in 8 cruises from the U.S. mid-Atlantic area of the outer continental to western Nova Scotia. The U.S. National Marine Fisheries Service, Federal Republic of Germany, Peoples Republic of Poland, and U.S. Coast Guard were the agencies that provided at-sea platforms. The greater portion of the survey coverage involved the Southern New England--Georges Bank--Gulf of Maine area, where 779.32 km/sup 2/ were sampled. Bird densities were greatest in the Georges Bank area where averages in excess of 30 birds/km/sup 2/ were recorded during the final quarter of 1978. All data collected during 1978 has been submitted to U.S.F.W.S. Migratory Bird and Habitat Research Laboratory in Luurel, MD for punching. Fifteen of 24 MBO cruises conducted in 1978 have been submitted to USFWS--MBHRL for punching and the remaining 9 have been transcribed. Seven of 16 MBO cruises conducted in 1976 have been transcribed.

  7. Predictable evolution toward flightlessness in volant island birds.

    Birds are prolific colonists of islands, where they readily evolve distinct forms. Identifying predictable, directional patterns of evolutionary change in island birds, however, has proved challenging. The "island rule" predicts that island species evolve toward intermediate sizes, but its general applicability to birds is questionable. However, convergent evolution has clearly occurred in the island bird lineages that have undergone transitions to secondary flightlessness, a process involving drastic reduction of the flight muscles and enlargement of the hindlimbs. Here, we investigated whether volant island bird populations tend to change shape in a way that converges subtly on the flightless form. We found that island bird species have evolved smaller flight muscles than their continental relatives. Furthermore, in 366 populations of Caribbean and Pacific birds, smaller flight muscles and longer legs evolved in response to increasing insularity and, strikingly, the scarcity of avian and mammalian predators. On smaller islands with fewer predators, birds exhibited shifts in investment from forelimbs to hindlimbs that were qualitatively similar to anatomical rearrangements observed in flightless birds. These findings suggest that island bird populations tend to evolve on a trajectory toward flightlessness, even if most remain volant. This pattern was consistent across nine families and four orders that vary in lifestyle, foraging behavior, flight style, and body size. These predictable shifts in avian morphology may reduce the physical capacity for escape via flight and diminish the potential for small-island taxa to diversify via dispersal. PMID:27071105

    Bird data have been collected through surveys, environmental assessments, and other observations for decades in the Oak Ridge National Environmental Research Park, located on the US Department of Energy’s Oak Ridge Reservation (ORR) in East Tennessee. Birds were recorded in a variety of habitats, including wetlands, interior forests, grasslands, ponds, corridors, forest edges, and more. Most of the information was gathered from waterfowl surveys conducted from 1990 to 2008, from Partners in Flight (PIF) breeding bird surveys conducted from 1995 to 2013, and from past publications and research on Reservation birds. We have also included our own observations and, in a few instances, credible observations of ORR birds of which we have been made aware through eBird or discussions with area ornithologists and bird watchers. For the period 1950-2014, we were able to document 228 species of birds on the ORR. Several of these species are known from historic records only, while others were not known to have ever occurred on the Reservation until recently. This report does not include PIF breeding bird data from the 2014 season or any records after July 2014. Twenty-two species--approximately 10% of the total number of species observed--have state-listed status in Tennessee as endangered, threatened, or in need of management. Of the 228 species we documented, 120 are believed to be breeding birds on the ORR.

    Cross-country comparison of DDE and PCB residue levels in cormorant, gull and tern eggs in Canada reveals that bird populations at the Great Lakes are most contaminated with those pollutants. DDE levels have been correlated with reproductive failure in Doublecrested Cormorants in the Great Lakes with eggshell thinning as a major factor. Low reproductive success in Herring Gull colonies at Lake Ontario is associated with high chlorinated hydrocarbon levels in eggs. Fish-eating birds in the Wabigoon River system, northwestern Ontario, are among the most known mercury contaminated birds. It is suggested that the effects of mercury on the reproduction of fish-eating birds should be further examined there. Fish-eating birds occupy the highest levels of the food web and magnification of toxic chemicals through prey organisms in this web makes those birds vulnerable to the effects of environmental contaminants. Since fish-eating birds are present everywhere in Canada's freshwater and marine habitats and occupy various niches there, they may serve as pollution indicators in various food chains of our aquatic environment. Colonial birds are especially valuable indicators as pollution effects on total bird populations can be studied. Baseline information on fish-eating bird populations should now be collected everywhere in Canada for measuring present and future effects of environmental pollutants, as well as other man-made disturbances on their populations.

  11. An ecological tax reform in Germany

    International Nuclear Information System (INIS)

    This study, being a part of the large research program 'External Effects of Energy Procurement' and coordinated by PROGNOS, concerns the distributional and macro-economic effects of the internalization of the external effects of the energy supply by means of an ecological tax reform. The PROGNOS study is focused on the costs and effects of energy production, procurement and consumption (in Germany), that are not taken care of by the market. Here a rough estimate is given of the macro-economic consequence and the distributional effects for the industrial sector and households in (West) Germany of an energy tax of which the revenues are 'reinjected' into the economy, mainly by lowering the financial burden on labour. First a description is given of the starting points of the study and the form of the energy tax. Subsequently attention is paid to the macro-economic effects, the sectoral effects, and the effects on the distribution of incomes for households. The model calculations for Western Germany and the Netherlands confirm the expectation that an ecological tax reform leads to the combined realization of employment and environmental objectives. Shifts in the sectoral structure may occur. Energy intensive branches of industry will have to give up a part of their market share in favour of labour-intensive sectors. The results also illustrate that there are several possibilities to prevent a change in the collective burden of regular expenses as a result of a tax or levy on energy, and that the effects of a fuel tax on the income distribution can be corrected. 5 figs., 19 tabs., 5 apps., 15 refs

  16. 2005 primary energy consumption in Germany

    International Nuclear Information System (INIS)

    According to preliminar calculations by the Arbeitsgemeinschaft Energiebilanzen (Working Party on Energy Balances, AGEB), the consumption of an aggregate 486 million TCE of primary energy resources in Germany last year was 1.3% below the level of the year before. Energy consumption was influenced by both the high level of prices and the development of the economy. Hardly any influence was attributable to the level of temperatures, which was largely unchanged compared to the figure of the year before. Oil consumption in 2005 in Germany dropped by nearly 2% to 174.8 million TCE. On the whole, oil with its 36% share in the energy balance remained by far the most important energy resource in Germany. Natural gas consumption of 110.4 million TCE was at the level of the year before. Its share in the primary energy balance rose slightly to 22.7%. Hard coal, because of lower use in power plants and the decline in iron making, showed a 4.6% drop in consumption to 62.8 million TCE. In this way, hard coal contributed 13% to total energy consumption. Lignite consumption dropped by 3.2% to 54.4 million TCE as a result of lower deliveries to power plants. Its 11.2% share in the total consumption of primary energy continued to make lignite the most important domestic energy resource. More than 90% of the lignite produced is used for electricity generation. The contribution to primary energy consumption of nuclear power dropped by more than 2% to 60.7 million TCE. Hydroelectric plants and wind power plants increased their contribution by 3.6%. The contribution to primary energy consumption made by all renewable energy resources rose to 4.6%. AGEB evaluates statistics of all areas of the power economy on the basis of standard criteria in order to combine these data in a comprehensive picture. Since 1994, the energy balances for Germany have been compiled by DIW on behalf of AGEB. (orig.)

  20. Detection of radioactivity in scrap in Germany

    International Nuclear Information System (INIS)

    Although Germany's scrap export exceeds the import, the imports of scrap amount to more than one million Mg per year. Radioactivity has been found mainly in imported scrap in Germany. This radioactivity can consist of surface contamination in scrap e.g. from the oil and gas industry, nuclear and other technical applications or of radiation sources, e.g. from medical or technical irradiation devices where the source has not been removed prior to scrapping. Fortunately really large sources have been involved in only very few occasions. More serious incidents have, however, been reported from other countries. Today, measurement facilities have been installed at the entrances to virtually all German foundries and larger scrap yards. These measurement facilities allow the swift measurement of whole lorry or freight car loads. The lower limit of detection is for some devices as low as ca. 5 nSv/h (dose rate increase above background at the detector) which is achieved by very advanced hardware and software. Additionally, simplified dose rate measurements are performed by German customs officials at the eastern borders for scrap loads to be imported into Germany. When activity is detected in a load, several options exist, like e.g.: (i) sending the scrap back to the sender; (ii) allowing the whole load to be melted down; (iii) careful unloading and separating the load with the aim of localizing and removing the contamination. This paper analyses these various options after detection, discusses the role of the competent authorities and evaluates the possible radiological consequences. Realistic dose calculations show that it is possible that a person may receive doses of several mSv or even 10 mSv if precautionary measures are neglected or if a larger source is not detected at all. This paper further addresses which types and amounts of radioactivity may be detected and which conclusions can be drawn from the dose rate at the detector. The continuous increase in the number

    Mapping the geogenic radon potential in Germany is a research project initiated by the German Federal Ministry for the Environment, Conservation and Reactor Safety. The project was aimed to develop a standard methodology for the estimation of a geogenic radon potential and to apply this method to map the region of Germany as an overview for planning purposes. The regionalisation results from a distance-weighted interpolation of the site-specific values of radon concentration in soil gas and in situ gas permeability of soils on a regular grid considering the corresponding geological units. The map of Germany in a scale of 1:2 million is based on the radon concentration in soil gas as an estimator of the geogenic radon potential assuming the 'worst case' of uniform highest permeability. The distribution is subdivided into categories of low ( 500 kBq/m3) radon concentration. High values occur especially in regions with granites and basement rocks of Paleozoic age, and are proven by measurements in 0.03% of the total area. Many of these regions are also known for their enhanced indoor values. The class with increased values takes a portion of 7.86% and likewise occurs mainly in regions with outcrops of folded and metamorphic basement, but also of some Meso- and Cenozoic sediments with increased uranium contents and/or higher emanation coefficients. For 67.3% of the country, the radon concentration is classified as 'medium', and an assignment to specific geological units cannot be made at the map scale considered. Low radon contents, where protective measures against radon are usually not considered, are found in the geologically rather homogeneous part of northern Germany with unconsolidated Cenozoic sediments, covering approximately 25% of the total country. It is of course not possible to predict the indoor radon concentration of single houses from these maps, because construction type and structural fabric of houses are essentially governing the extent to which

    Since oil was first extracted, pollution of the seas and oceans or adjacent coasts has been an obstacle for the oil industry and environmental activists. The major concern is oil discharge into the water which may lead to birds' affliction or death, besides putting marine life in jeopardy. This paper presents the first description of the design and implementation of a new bird washing machine that can be utilized for cleaning of oil-coated birds with the minimum of stress. The machine is equipped with a pneumatic system comprised of 19 moving nozzles which evenly cover the bird's body and is designed to be used in contaminated environments where a vast number of birds are affected. Experimental trials show an improvement in operation efficiency compared to other methods in a reduction in washing time, energy consumption and a decrease in fatality rate of washed birds.

    Full Text Available Three new or from this site previously unrecorded birds are described from the Middle Eocene of Messel (Hessen, Germany. Serudaptus pohli n. gen. n. sp. is a new taxon of the Pseudasturidae and is distinguished from the other species of this family by its short and stout tarsometatarsus and the long and strong claws. An isolated foot of a gruiform bird is assigned to Idiornis cf. itardiensis (Idiornithidae and would, if this assignment can be confirmed, demonstrate the existence of this species for a period of 23 million years. The proportions of the toes suggest that Idiornis cf. itardiensis was less cursorial than its next recent relatives, the Cariamidae. In addition thereto, an exceptionally well preserved skeleton of a sandcoleid bird (Coliiformes: Sandcoleidae gives new information on the osteology and feathering of sandcoleid birds. The specimen resembles the genera Eoglaucidium and Anneavis but it has not been possible to assign it to one of these two genera with certainty.

  11. Reversing course: Germany`s response to the challenge of transboundary air pollution

    Energy Technology Data Exchange (ETDEWEB)

    Sprinz, D.F.; Wahl, A.

    1998-03-01

    Perhaps like no other country, Germany has radically changed its policies towards regulating air pollution in the European context. Acting originally as a dragger in the 1970s to regulate transboundary air pollutants due to pessimism about the relationship between causes and effects, Germany responded very decisively to its own damage assessment in the early 1980s. In particular the adverse effects to forests (`Waldsterben` or forest decline) led to the formulation of strict air pollution regulations in the domestic context, efforts to spread the regulatory system within the European Union, and activities within the United Nations Economic Commission for Europe to foster stronger, continent-wide emission reductions. Using three conceptual models (rational actor, domestic politics, and social learning), we show that Germany deviated strongly from the ideal policy cycle consisting of (i) domestic policy formulation, (ii) international negotiations, as well as (iii) implementation and compliance with the provisions of international environmental agreements. Both national policy-making as well as partial implementation have been well on the way towards compliance even before Germany entered international negotiations on substantive protocols. Therefore, one may conclude from this country study that push countries may use the results of their national policy processes to influence the policy of other countries. (orig.)

  14. Artificial insemination for breeding non-domestic birds

    Gee, G.F.; Temple, S.A.

    1978-01-01

    Captive breeding of non-domestic birds has increased dramatically in this century, and production of young often exceeds that of the same number of birds in their native habitat. However, when infertility is a problem, artificial insemination can be a useful method to improve production. Artificial insemination programs with non-domestic birds are relatively recent, but several notable successes have been documented, especially with cranes and raptors. Three methods of artificial insemination are described--cooperative, massage, and electroejaculation. Cooperative artificial insemination requires training of birds imprinted on man and is used extensively in some raptor programs. The massage technique generally is used when there are larger numbers of birds to inseminate since it requires less training of the birds than with the cooperative method, and a larger number of attempted semen collections are successful. Although the best samples are obtained from birds conditioned to capture and handling procedures associated with the massage method, samples can be obtained from wild birds. Semen collection and insemination for the crane serves to illustrate some of the modifications necessary to compensate for anatomical variations. Collection of semen by electrical stimulation is not commonly used in birds. Unlike the other two methods which require behavioral cooperation by the bird, electroejaculation is possible in reproductively active birds without prior conditioning when properly restrained. Fertility from artificial insemination in captive non-domestic-birds has been good. Although some spermatozoal morphology has been reported, most aspects of morphology are not useful in predicting fertility. However, spermatozoal head length in the crane may have a positive correlation with fertility. Nevertheless, insemination with the largest number of live spermatozoa is still the best guarantee of fertile egg production.

    This study was carried out to determine chewing louse species of wild birds in the Ria Formosa Natural Park, located in southern Portugal. In addition, the hypothesis that bird age, avian migration and social behaviour have an impact on the louse prevalence was tested. Between September and December of 2013, 122 birds (belonging to 10 orders, 19 families, 31 genera and 35 species) captured in scientific ringing sessions and admitted to the Wildlife Rehabilitation and Investigation Centre of Ria Formosa were examined for lice. Twenty-six (21.3%) birds were found to be infested with at least one chewing louse species. The chewing lice identified include 18 species. Colonial birds (34.9%) and migratory birds (29.5%) had statistically significant higher prevalence than territorial birds (6.8%) and resident birds (13.1%), respectively. This paper records 17 louse species for the first time in southern Portugal: Laemobothrion maximum, Laemobothrion vulturis, Actornithophilus piceus lari, Actornithophilus umbrinus, Austromenopon lutescens, Colpocephalum heterosoma, Colpocephalum turbinatum, Eidmanniella pustulosa, Nosopon casteli, Pectinopygus bassani, Pseudomenopon pilosum, Trinoton femoratum, Trinoton querquedulae, Craspedorrhynchus platystomus, Degeeriella fulva, Falcolipeurus quadripustulatus, Lunaceps schismatus. Also a nymph of the genus Strigiphilus was collected from a Eurasian eagle-owl. These findings contribute to the knowledge of avian chewing lice from important birds areas in Portugal. PMID:26899014

    ABSTRACT.—Bird use of small canopy gaps within mature forests has not been well studied, particularly across multiple seasons. We investigated seasonal differences in bird use of gap and forest habitat within a bottomland hardwood forest in the Upper Coastal Plain of South Carolina. Gaps were 0.13- to 0.5-ha, 7- to 8-year-old group-selection timber harvest openings. Our study occurred during four bird-use periods (spring migration, breeding, postbreeding, and fall migration) in 2001 and 2002. We used plot counts and mist netting to estimate bird abundance in canopy gaps and surrounding mature forest habitats. Using both survey methods, we observed more birds, including forest-interior species, forest-edge species, field-edge species, and several individual species in canopy gap and gap-edge habitats than in surrounding mature forest during all periods. Interactions between period and habitat type often were significant in models, suggesting a seasonal shift in habitat use. Bird activity generally shifted between the interior of canopy gaps and the immediate gap edge, but many species increased their use of forested habitat during the breeding period. This suggests that many species of birds selectively choose gap and gap-edge habitat over surrounding mature forest during the non-breeding period. Creation of small canopy gaps within a mature forest may increase local bird species richness. The reasons for increased bird activity in gaps remain unclear.

    2014-01-01

    Our knowledge of the avian tree of life remains uncertain, particularly at deeper levels due to the rapid diversification early in their evolutionary history. They are the most abundant land vertebrate on the planet and have been of great historical interest to systematists. Birds are also economically and ecologically important and as a result are intensively studied, yet despite their importance and interest to humans around 13% of taxa currently on the endangered species list perhaps as a result of human activity. Despite all this no comprehensive phylogeny that includes both extinct and extant species currently exists. Here we present a species-level supertree, constructed using the Matrix Representation with Parsimony method, of Aves containing approximately two thirds of all species from nearly 1000 source phylogenies with a broad taxonomic coverage. The source data for the tree were collected and processed according to a strict protocol to ensure robust and accurate data handling. The resulting tree topology is largely consistent with molecular hypotheses of avian phylogeny. We identify areas that are in broad agreement with current views on avian systematics and also those that require further work. We also highlight the need for leaf-based support measures to enable the identification of rogue taxa in supertrees. This is a first attempt at a supertree of both extinct and extant birds, it is not intended to be utilised in an overhaul of avian systematics or as a basis for taxonomic re-classification but provides a strong basis on which to base further studies on macroevolution, conservation, biodiversity, comparative biology and character evolution, in particular the inclusion of fossils will allow the study of bird evolution and diversification throughout deep time.

Among them is a remarkable ability to perceive the intensity and direction of the Earth's magnetic field. Biologically credible mechanisms for the sensing of such weak fields (25-65 microtesla) are scarce and in recent years just two proposals have emerged as frontrunners. One involves biogenic iron-containing nanoparticles; the other relies on the magnetic sensitivity of short-lived photochemical intermediates known as radical pairs. The latter began to attract attention following the proposal 15 years ago that the necessary physics and chemistry could take place in the bird's retina in specialised photoactive proteins called cryptochromes. The coherent dynamics of the electron-nuclear spin systems of pairs of photo-induced radicals is conjectured to form the basis of the sensing mechanism even though the interaction of an electron spin with the geomagnetic field is six orders of magnitude smaller than the thermal energy. The possibility that slowing decohering, entangled electron spins could form the basis of an important sensory mechanism has qualified radical pair magnetoreception for a place under the umbrella of ``Quantum Biology.'' In this talk, I will introduce the radical pair mechanism, comment on the roles of entanglement and quantum coherence, outline some of the experimental evidence for the cryptochrome hypothesis, and summarize what still needs to be done to determine whether birds (and maybe other animals) really do use a chemical compass to find their way around.

  9. Elevational distribution and extinction risk in birds.

    Directory of Open Access Journals (Sweden)

    Rachel L White

    Full Text Available Mountainous regions are hotspots of terrestrial biodiversity. Unlike islands, which have been the focus of extensive research on extinction dynamics, fewer studies have examined mountain ranges even though they face increasing threats from human pressures - notably habitat conversion and climate change. Limits to the taxonomic and geographical extent and resolution of previously available information have precluded an explicit assessment of the relative role of elevational distribution in determining extinction risk. We use a new global species-level avian database to quantify the influence of elevational distribution (range, maximum and midpoint on extinction risk in birds at the global scale. We also tested this relationship within biogeographic realms, higher taxonomic levels, and across phylogenetic contrasts. Potential confounding variables (i.e. phylogenetic, distributional, morphological, life history and niche breadth were also tested and controlled for. We show that the three measures of elevational distribution are strong negative predictors of avian extinction risk, with elevational range comparable and complementary to that of geographical range size. Extinction risk was also found to be positively associated with body weight, development and adult survival, but negatively associated with reproduction and niche breadth. The robust and consistent findings from this study demonstrate the importance of elevational distribution as a key driver of variation in extinction dynamics in birds. Our results also highlight elevational distribution as a missing criterion in current schemes for quantifying extinction risk and setting species conservation priorities in birds. Further research is recommended to test for generality across non-avian taxa, which will require an advance in our knowledge of species' current elevational ranges and increased efforts to digitise and centralise such data.

    In this paper we are interested to the zygodactyly phenomenon in birds, and in particolar in parrots. This arrangement, common in species living on trees, is a distribution of the foot with two toes facing forward and two back. We give a model for the foot, and thanks to the methods of iterated function system we are able to describe the reachability set. Moreover we give a necessary and sufficient condition for the grasping problem. Finally we introduce a hybrid dynamical system modeling owl...

    Plica neuropathica also known as “birds nest” is irreversible matting of hair seen in otherwise healthy individuals and is usually associated with use of ionic/herbal soaps, shampoos, parasitic infestations, psychiatric alterations, or neglect. Anagen effluvium is a known side effect of many immunosuppressive drugs. Rarely matting of hair has been reported following azathioprine. We report plica neuropathica in two chronically ill patients on immunosuppressive drugs, that is, azathioprine and methotrexate along with a review of literature of its etiological factors and pathogenesis.

  17. The energy future of West Germany

    International Nuclear Information System (INIS)

    The effect on the West German energy policy of environmentalists, politicians and trade unions is discussed. It is felt that without a growing nuclear power programme, possibly based in the longer term on fast breeder or high temperature thorium cycle systems, the only way in which West Germany can maintain its economic growth through the next two decades would be to rely on imported oil and coal. It is difficult to assess the precise effects of the hold-back of the nuclear programme by anti-nuclear pressure groups. Some of them could be wholly admirable if they lead to more efficient end use of energy and make the world a safer place to live in; at the same time too rapid a change could lead to extremely undesirable tensions and political problems. Some compromise is essential, and there is still time to achieve a proper balance; but the way ahead must be clarified before the beginning of 1980 if West Germany is to achieve a satisfactory and adequate energy supply by 1990, and thereafter.

  18. Germany's Solar Cell Promotion: An Unfolding Disaster

    International Nuclear Information System (INIS)

    This article is a German-French translation of a paper originally published in July 2012 in 'Ruhr Economic Papers' no. 353. The original article revisits an analysis by Frondel, Ritter and Schmidt (2008) of Germany's Renewable Energy Act, which legislates a system of feed-in tariff s to promote the use of renewable energies. As in the original article, we argue that Germany's support scheme subsidizes renewable energy technologies not based on their long-term market potential, but rather on their relative lack of competitiveness, with the photovoltaic (PV) technology enjoying high feed-in tariffs, currently over double those of onshore wind. The result is explosive costs with little to show for either environmental or employment benefits. Indeed, we document that the immense costs foreseen by Frondel and colleagues have materialized: Our updated estimate of the subsidies for PV, at 100 Bn euros, exceeds their expectations by about 60%. Moreover, with installed PV capacities growing at a rapid rate, these costs will continue to accumulate, diverting resources from more cost-effective climate protection instruments

  19. LWR spent fuel management in Germany

    International Nuclear Information System (INIS)

    The spent fuel management strategy in the Federal Republic of Germany is based alternatively on interim storage and subsequent reprocessing of spent fuel or on extended storage and direct disposal of spent fuel. By economic and strategic reasons the spent fuel burnup is presently achieving 50 GWd/tHM and will targeting 55 GWd/tHM batch average. Recently the CASTOR V/19 license is issued to store spent fuel assemblies (SFAs) with up to 55 GWd/tU burnup (batch average) for 40 years. The integral pool storage capacity in Germany is 5600 tHM without the necessary full core reserve. The AFR spent fuel storage sites of Ahaus ( 4200 tHM) and Gorleben (3800 tHM) are in operation. The PKA pilot-facility to condition the SFAs is in the final state of erection and alternative approaches for SFAs with a higher burnup and/or MOX fuel are under investigation. The underground exploration of the Gorleben salt dome is in progress. Presently the non heat generating waste is disposed in the former Morsleben salt mine. Licensing of the larger Konrad iron mine for that purpose is under treatment. (author)

  20. Status of wind energy in Germany

    Energy Technology Data Exchange (ETDEWEB)

    By the end of 1995 in total 3655 wind turbines (WT`s) were installed in Germany with a total capacity of 1,136 MW. In the year 1995 alone the WT installations grew by 1,070 units with 505 MW. About 40% of the 1995 installations were sold to inland states of Germany with their lower wind speed potential. This fast development occurred in parallel to continuously reduced local state and federal subsidies. The further development is based mainly on the guaranteed reimbursement due to the Electricity Feed Law. But since some time the electricity utilities fight back on all legal and political levels to get cancelled the unloved Electricity Feed Law and since two years the building construction law with the foreseen privilege for WT`s is discussed without any result. All these difficulties affect investors and credit giving banks in such a negative way, that the further annual increase in wind power installation for 1996 could be 10 to 20% less than in 1995. Many of the new commercial Megawatt WT`s have pitch control and variable rotor speed which cause better electrical power quality and lower life time loads. From statistical evaluations on technical data of WT`s a good overview of the further development is derived. 8 refs., 10 figs.
