Since 1979, the group belonging to Departments of Veterinary Microbiology, Veterinary Public Health and the Avian Zoonoses Research Centre, Faculty of Agriculture, Tottori University is continuing isolation of avian influenza virus from such migratory waterfowls as whistling swan, pintail and tufted dugs flying from Siberia and/or northern China. They have already isolated many interesting influenza viruses. Serotype of the isolates is various; some H5 and H7 and human types of viruses were also isolated; and its pathogenicity for chickens is not high. It was interested that low pathogenic H5N3 virus isolated from whistling swan acquired severe pathogenicity during passage in chicks.

Full Text Available In contrast to previous discussions in the literature treating cosmopolitan and local as two distinct groups of scientists, this paperi demonstrates the notion of cosmopolitan and local as a dual orientation of highly motivated scientists. This dual orientation is derived from institutional motivation, which is a determinant of both high quality basic research and accomplishment of non-research organizational activities. The dual orientation arises in a context of similarity of the institutional goal of science with the goal of the organization; the distinction between groups of locals and cosmopolitans derives from a conflict between two goals.

Highly migratory, cosmopolitan oceanic sharks often exhibit complex movement patterns influenced by ontogeny, reproduction, and feeding. These elusive species are particularly challenging to population genetic studies, as representative samples suitable for inferring genetic structure are difficult to obtain. Our study provides insights into the genetic population structure one of the most abundant and wide-ranging oceanic shark species, the blue shark Prionace glauca, by sampling the least mobile component of the populations, i.e., young-of-year and small juveniles (<2 year; N = 348 individuals), at three reported nursery areas, namely, western Iberia, Azores, and South Africa. Samples were collected in two different time periods (2002-2008 and 2012-2015) and were screened at 12 nuclear microsatellites and at a 899-bp fragment of the mitochondrial control region. Our results show temporally stable genetic homogeneity among the three Atlantic nurseries at both nuclear and mitochondrial markers, suggesting basin-wide panmixia. In addition, comparison of mtDNA CR sequences from Atlantic and Indo-Pacific locations also indicated genetic homogeneity and unrestricted female-mediated gene flow between ocean basins. These results are discussed in light of the species' life history and ecology, but suggest that blue shark populations may be connected by gene flow at the global scale. The implications of the present findings to the management of this important fisheries resource are also discussed.

Full Text Available The smaller the world due to mass migration and new technology, the bigger the conflicts due to perceiving ourselves as more different from one-another than ever. There is new hope, however, because cosmopolitanism has made a spectacular comeback to save the day. Unfortunately, everyone seems to be so caught up arguing whether the glass of cosmopolitanism is half full or half empty, that cosmopolitanism is, in fact, causing quite a stir, thus defeating its harmonious purpose. This paper calls for a time-out and proposes a cosmopolitan-approach to cosmopolitanism.
In recent years, the idea of cosmopolitanism has variously been explored as a political philosophy, a moral theory and a cultural disposition. In each of these cases, this new interest in cosmopolitanism is based upon a recognition that our world is increasingly interconnected and interdependent globally, and that most of our problems are global…

Full Text Available Abstract Background Understanding the demographic processes underlying population dynamics is a central theme in ecology. Populations decline if losses from the population (i.e., mortality and emigration exceed gains (i.e., recruitment and immigration. Amphibians are thought to exhibit little movement even though local populations often fluctuate dramatically and are likely to go exinct if there is no rescue effect through immigration from nearby populations. Terrestrial salamanders are generally portrayed as amphibians with low migratory activity. Our study uses demographic analysis as a key to unravel whether emigration or mortality is the main cause of "losses" from the population. In particular, we use the analysis to challenge the common belief that terrestrial salamanders show low migratory activity. Results The mark-recapture analysis of adult salamanders showed that monthly survival was high (> 90% without a seasonal pattern. These estimates, however, translate into rather low rates of local annual survival of only ~40% and suggest that emigration was important. The estimated probability of emigration was 49%. Conclusion Our analysis shows that terrestrial salamanders exhibit more migratory activity than commonly thought. This may be due either because the spatial extent of salamander populations is underestimated or because there is a substantial exchange of individuals between populations. Our current results are in line with several other studies that suggest high migratory activity in amphibians. In particular, many amphibian populations may be characterized by high proportions of transients and/or floaters.
Full Text Available Interpretations of Kant usually focus on his legal or political cosmopolitanism, a cluster of ideas revolving around perpetual peace, an international organisation, the reform of international law, and what Kant has termed cosmopolitan law or the law of world citizens (Weltbürgerrecht. In this essay, I argue that there are different cosmopolitanisms in Kant, and focus on the relationship among political, legal or juridical, moral and ethico-theological cosmopolitanisms. I claim that these form part of a comprehensive system and are fully compatible with each other, given Kant's framework. I conclude that it is not self-evident that one can pick out some elements of this greater system as if they were independent of it.

Full Text Available Byrne’s paper consists of two parallel texts. The first explores the limits of cosmopolitanism in practice, taking as its subject the Life in the UK Citizenship Test, inaugurated under the Labour Government in 2005. It argues that the test exemplifies the predicament of all attempts at cosmopolitan hospitality as unconditional welcoming, through a discussion of the relation between questioning and welcoming the stranger. Establishing the relationship between cosmopolitanism and hospitality as envisaged in Derrida’s reading of Kant it asks what kind of cosmopolitan hospitality is either possible or desirable by exploring what Derrida calls the ‘perversions’ inherent in the structures of hospitality. It focuses on the concept of the ‘trick questions’ that the state asks the foreigner observed by Derrida in his reading of The Apology of Socrates; questions that seem to invite answers but foreclose the possibilities of a free response. The second text asks how this logic that Derrida identifies can be pushed or coaxed into new ways of addressing the perceived threats of ‘unconditional’ hospitality through a reading of ‘unconditional hospitality’ as queer in the work of Tove Jansson.

Polychlorinated biphenyls are highly toxic organic contaminants. Due to their chemical properties they had wide application in industry and agriculture in the 20th century. In 2001 the production of PCBs has been prohibited almost worldwide. Environmental contamination has been found in soils, water, and air where there were PCB production sites. They have been detected in fish, birds and animals of migratory species, retaining transboarding transfer. Several migratory species of birds (Taiga bean goose, greater white-fronted goose, lesser white fronted goose and barnacle goose) are a diet for indigenous people. PCBs accumulating in the human body affect all systems and organs. This article reviews the contribution of migratory bird species in transboarding transfer of highly toxic contaminants in the Nenets Autonomous Area, Kolguev island (Russian Arctic).

Locusts represent an impressive example of migratory polyphenism, with high densities triggering a switch from a solitarious, shorter dispersal range, and sometimes greenish phenotype to a gregarious and sometimes darker form exhibiting behavioral, morphological and physiological traits associated with long-distance migratory swarms. While such polyphenism has been well documented in Locusta migratoria and Schistocerca gregaria, the extent to which other grasshoppers exhibit this type of migratory polyphenism is unclear. Anecdotally, the Chinese grasshopper, Oedaleus asiaticus, forms migratory swarms comprised mostly of a darker, brown-colored morph, but also exhibits a non-migratory green-colored morph that predominates at low densities. In a population in Inner Mongolia not currently exhibiting migratory swarms, we found that while green and brown O. asiaticus are found concurrently across our sampled range, only brown grasshoppers were found in high densities. Differences between field-collected brown and green forms matched some but not key predictions associated with the hypothesis that the brown form is morphologically and physiologically specialized for gregarious migration. Controlling for body mass, brown forms had more massive thoraxes, abdomens and legs, and higher metabolic rates, but not more flight muscle or lipid stores. Further, the brown and green grasshoppers did not differ in gregarious behavior, and neither would fly in multiple lab and field trials. Lab or field-rearing at high densities for one-to-multiple juvenile instars caused grasshoppers to exhibit some morphological traits predicted to benefit migration (larger wings and a shift in relative mass from abdomen to thorax), but did not change color or induce flight behavior. One hypothesis to explain these data is that a migratory form of O. asiaticus is partially triggered by high field densities, but that existing ecological conditions blocked full expression of such traits (and outbreak

Migratory waterfowl are natural reservoirs for low pathogenic avian influenza viruses (AIVs) and may contribute to the long-distance dispersal of these pathogens as well as spillover into domestic bird populations. Surveillance for AIVs is critical to assessing risks for potential spread of these viruses among wild and domestic bird populations. The Delmarva Peninsula on the east coast of the United States is both a key convergence point for migratory Atlantic waterfowl populations and a region with high poultry production (>4,700 poultry meat facilities). Sampling of key migratory waterfowl species occurred at 20 locations throughout the Delmarva Peninsula in fall and winter of 2013–14. Samples were collected from 400 hunter-harvested or live-caught birds via cloacal and oropharyngeal swabs. Fourteen of the 400 (3.5%) birds sampled tested positive for the AIV matrix gene using real-time reverse transcriptase PCR, all from five dabbling duck species. Further characterization of the 14 viral isolates identified two hemagglutinin (H3 and H4) and four neuraminidase (N2, N6, N8, and N9) subtypes, which were consistent with isolates reported in the Influenza Research Database for this region. Three of 14 isolates contained multiple HA or NA subtypes. This study adds to the limited baseline information available for AIVs in migratory waterfowl populations on the Delmarva Peninsula, particularly prior to the highly pathogenic AIV A(H5N8) and A(H5N2) introductions to the United States in late 2014.

Full Text Available The article defines cosmopolitanism in China through the prisms of nationalism, multiculturalism and consumerism. This definition makes it possible to better understand the proliferation of interactive, or high-quality, cosmopolitanism through the activity of state agencies in modern China. In this article the system of higher education is presented as one of the most significant state agency, which has a strong, though indirect, influence on accepting the principles of cosmopolitan approach for further self-advancement of individuals. It is substantiated that the quantitative limitations of the opportunities in the higher education system can be overcome by developing a collective level of cosmopolitanism.

It is commonly perceived that the ‘globalization of science’ may result in a ‘Westernization of science’. In this paper, however, I use the case of stem cell science in China to demonstrate that developing countries are sometimes able to effectively shape the norms of global/local scientific exchange. Based on interviews with 38 stem cell scientists in six Chinese cities in early 2008, this paper elucidates Chinese scientists’ outlook towards cross-border collaborations and the effects that the internationalization of science has had on everyday laboratory operations. Findings suggest that although there still exists an asymmetry of scientific influence, and in many aspects China is still ‘catching-up’ to the West, there is also a changing nature of communication beyond borders. One key aspect of recent international scientific development is the growing necessity for local stakeholders to acquire a global mindset and to compare, reflect and accommodate diverse interests. This is what I define as the ‘cosmopolitanization of science’. The study empirically examines the sociological and methodological implications of the cosmopolitanization process and further develops Ulrich Beck’s cosmopolitan theory by delineating four main features of the ‘cosmopolitanization of science’: shared future benefits, passive ethicization, reflexive negotiation, and continuous performance.

Approximately 100 migratory birds, including whooper swans and pochards, were found dead in the Sanmenxia Reservoir Area of China during January 2015. The causative agent behind this outbreak was identified as H5N1 highly pathogenic avian influenza virus (HPAIV). Genetic and phylogenetic analyses revealed that this Sanmenxia H5N1 virus was a novel reassortant, possessing a Clade 220.127.116.11c HA gene and a H9N2-derived PB2 gene. Sanmenxia Clade 18.104.22.168c-like H5N1 viruses possess the closest genetic identity to A/Alberta/01/2014 (H5N1), which recently caused a fatal respiratory infection in Canada with signs of meningoencephalitis, a highly unusual symptom with influenza infections in humans. Furthermore, this virus was shown to be highly pathogenic to both birds and mammals, and demonstrate tropism for the nervous system. Due to the geographical location of Sanmenxia, these novel H5N1 viruses also have the potential to be imported to other regions through the migration of wild birds, similar to the H5N1 outbreak amongst migratory birds in Qinghai Lake during 2005. Therefore, further investigation and monitoring is required to prevent this novel reassortant virus from becoming a new threat to public health.

Full Text Available Abstract We reviewed the occurrences and distributional patterns of migratory species of birds in Brazil. A species was classified as migratory when at least part of its population performs cyclical, seasonal movements with high fidelity to its breeding grounds. Of the 1,919 species of birds recorded in Brazil, 198 (10.3% are migratory. Of these, 127 (64% were classified as Migratory and 71 (36% as Partially Migratory. A few species (83; 4.3% were classified as Vagrant and eight (0,4% species could not be defined due to limited information available, or due to conflicting data.

Introduction of Asian strain H5N1 Highly Pathogenic avian influenca via waterfowl migration is one potential route of entry into the United States. In conjunction with state, tribe, and laboratory partners, the United States Department of Agriculture collected and tested 124,603 wild bird samples in 2006 as part of a national surveillance effort. A sampling plan was devised to increase the probability fo detecting Asian strain H5N1 at a national scale. Band recovery data were used to identify and prioritize sampling for wild migratory waterfowl, resulting in spatially targeted sampling recommendations focused on reads with high numbers of recoveries. We also compared the spatial and temporal distribution of the 2006 cloacal and fecal waterfowl sampling effort to the bird banding recovery data and found concordance between the two .Finally, we present improvements made to the 2007 fecal sampling component of the surveillance plan and suggest further improvements for future sampling.
Discussions of cosmopolitanism in Bombay often focus on the rubrics of communal tension, tolerance, and violence, and frequently report the decline of a once cosmopolitan city, especially as a result of the communal riots and bombings that occurred in the early 1990s. However, claims that the city has undergone a general social transformation since the 1990s need to be tempered by the multiple forms of cosmopolitan imaginations and practices that exist in the city. There is a wide variety ...

Full Text Available In this paper I will approach the issue of feminism and cosmopolitanism in order to give arguments in sustaining the fact that, today, feminism and cosmopolitanism are inevitable connected. In constructing my discourse I will begin by laying out the main ideas of cosmopolitanism, followed by a presentation of the construction of the feminist movement over time, inter-relating these two discourses at the end of the analysis. Connected with political ethics, political theory and political philosophy, the theoretical framework selected for this paper is based on the cosmopolitan theory developed by scholars like Martha Nussbaum, Fiona Robinson and Kwame Anthony Appaih who, underlining universality, define cosmopolitism as a universal concern with every human life and its well-being, but who are also giving value to the differences (seen as cultural or/ and of identity insofar as they are not harmful to people.
Full Text Available The paper critically examines the forms the idea of cosmopolitan hospitality takes both in the contemporary debate on the political rights of immigrants, and on the problem of global justice. Showing that the original Kantian meaning of hospitality presents some important limits in terms of the problems which contemporary political theory confronts with, the paper will also discuss some of the practical or normative difficulties faced by the contemporary cosmopolitanism, and how to address these difficulties.

Atlantic tarpon, Megalops atlanticus, are highly migratory euryhaline predators that occupy different habitats throughout ontogeny. Specifically, Atlantic tarpon are known to inhabit oligohaline waters, although the frequency and duration of movements across estuarine gradients into these waters are relatively unknown. This species supports over a two billion dollar industry within the Gulf of Mexico and is currently listed as vulnerable under the International Union for the Conservation of Nature (IUCN). A new non-lethal method for reconstructing migrations across estuaries relies on trace element and stable isotope compositions of growth increments in scales. We analyzed Atlantic tarpon scales from the Texas coast to validate this method using inductively coupled plasma mass spectrometry (ICP-MS) for trace elements and isotope ratio mass spectrometry (IR-MS) for stable isotope ratios. Multiple scales were also taken from the same individual to confirm the consistency of elemental uptake within the same individual. Results show that scale Ba:Ca, Sr:Ca and δ13C are effective proxies for salinity, while enrichments in δ15N are consistent with known ontogenetic trophic shifts. In addition, chemical transects across multiple scales from the same individual were highly consistent, suggesting that any non-regenerated scale removed from a fish can provide equivalent time series. Continuous life history profiles of scales were obtained via laser ablation transects of scale cross-sections to quantify trace element concentrations from the core (youngest increments) to the edge (oldest increments). Stable isotope and trace element results together indicate that behavior is highly variable between individuals, with some but not all fish transiting estuarine gradients into oligohaline waters. Our findings will provide novel opportunities to investigate alternative non-lethal methods to monitor fish migrations across chemical gradients.
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 This study questions the “clash of civilizations” thesis. Referring to the cosmopolitanization process as defined by Beck and Sznaider (2010, I analyze the cosmopolitanization of feminism, that is, the gradual recognition of “the others’ others”, the women, through the evolution of their political rights—the right to elect and be elected—at a global level. In this context, the descriptive representation of women, their substantive representation, and their voices within civil society in the North and the South highlight the fact that feminism is undergoing a process of cosmopolitanization, albeit in a slow and sporadic way. I present this argument from a postcolonial feminist perspective and base my research on NGOs’ data and on data provided by the Inter-Parliamentary Union and UN-Women. First, I analyze the cosmpolitanization process as applied to feminism. Then, following Beck and Sznaider (2010, I describe how this process is articulated ‘from above’ (top-down cosmopolitanization, referring to electoral data from around the world and to international law. Further, I relate to the cosmopolitanization of feminism ‘from below’, referring to feminist theories, cyberfeminism and the global civil/feminist society. In conclusion, I discuss the common future of feminism and cosmopolitanism.

Full Text Available Immanuel Kant's Cosmopolitanism has come to stand alongside Political Realism and Liberal Internationalism as one of three broad theories of ethics in international relations. Yet Cosmopolitanism has been subjected to criticisms that the universal norms identified by Kant - including such norms as hospitality, reciprocity, and publicity (transparency and free political participation - are Western and Eurocentric in nature, incompatible with cultural pluralism, and lack the justification and legitimacy for the broad-based consensus required for a Cosmopolitan political sphere to emerge among the world’s diverse peoples. This paper seeks to address these criticisms of Cosmopolitanism by studying examples of Cosmopolitan norms in action. These examples have been drawn from diverse regions around the globe to represent self-organized, 'self-legislating', civil societies that have themselves developed the rules that guide their behaviour and the terms of their discourse in the absence of a centralized governing authority. It is hoped that this approach will contribute to this ongoing debate by demonstrating that Cosmopolitan norms can be found in a diverse array of human communities and cultures, that Cosmopolitan norms are not only compatible with pluralism, but are instrumental in its success and vitality, and, finally, that the flourishing of such civil societies shows that the adoption of Cosmopolitan norms are strongly correlated with successful outcomes and well-being.
In this paper, I look at the way in which a maximin egalitarian theory of justice should deal with the greenhouse effect and its consequences. I adopt both a cosmopolitan and a 'local' approach (in Elster's sense). The paper concentrates on three dimensions of a Kyoto-type international regime raising issues of justice: the determination of a global cap on emissions for a given period, the way in which emission quotas should be distributed among countries for each period, and the questions arising from the tradability of such quotas. Regarding the cap issue, it is subject to both inter-generational and intra-generational constraints of justice. I show that a weak intra-generational principle of compensation is likely to lead to radically demanding implications. As to the initial allocation issue, I look at five possible reasons why egalitarians may want to depart from a population-based allocation among countries. Special attention is devoted to three of them: grand-fathering, the disadvantageous geographical specificities of some countries and historical emissions. I specify the extent to which such a departure from a population-based mode of allocation can be justified on egalitarian grounds. Finally, I look at possible objections to the tradability of such quotas, concluding that they are not sufficient to shift toward non-tradable quotas. (author)

Executive Summary: This Surveillance Plan (Plan) describes plans for conducting surveillance of wild birds in the United States and its Territories and Freely-Associated States to provide for early detection of the introduction of the H5N1 Highly Pathogenic Avian Influenza (HPAI) subtype of the influenza A virus by migratory birds during the 2009 surveillance year, spanning the period of April 1, 2009 - March 31, 2010. The Plan represents a continuation of surveillance efforts begun in 2006 under the Interagency Strategic Plan for the Early Detection of H5N1 Highly Pathogenic Avian Influenza in Wild Migratory Birds (U.S. Department of Agriculture and U.S. Department of the Interior, 2006). The Plan sets forth sampling plans by: region, target species or species groups to be sampled, locations of sampling, sample sizes, and sampling approaches and methods. This Plan will be reviewed annually and modified as appropriate for subsequent surveillance years based on evaluation of information from previous years of surveillance, changing patterns and threats of H5N1 HPAI, and changes in funding availability for avian influenza surveillance. Specific sampling strategies will be developed accordingly within each of six regions, defined here as Alaska, Hawaiian/Pacific Islands, Lower Pacific Flyway (Washington, Oregon, California, Idaho, Nevada, Arizona), Central Flyway, Mississippi Flyway, and Atlantic Flyway.
Full Text Available Throughout his life Pinter always showed, both as artist and as social being, a profound respect for the rights of the individual and human dignity. His dramatic output as well as his overt political activity demonstrate his unbroken adherence to the ideology and behaviour of a citizen of the world. My endeavour in this paper will be to argue about what I shall call Pinter’s visceral cosmopolitanism. This approach, on the one hand, reads his political actions through the highly politicized agenda of the contemporary cosmopolitan discourse and, on the other hand, it adopts a more retrospective point of view, which seeks to find a fundamental correspondence between the Pinteresque uncertainty, fear and ambiguity and Immanuel Kant’s rather more ethical understanding of cosmopolitanism, especially his novel idea of hospitality.
Full Text Available This study, concerning the development of cosmopolitan citizenship, draws on theories of human development and capabilities (Sen 1999; Nussbaum 2000 from a social justice perspective, where individual wellbeing is articulated as having the freedom to live a life of one’s choosing. In the context of an English to Speakers of Other Languages (ESOL classroom this involves paying attention to pedagogical strategies, power dynamics and curriculum content as a means of developing valued beings and doings (or capabilities and functionings as they are described in the literature. Sample activities are presented and evaluated to see to what extent they achieve the desired end. These include critical pedagogical interventions, students’ artefacts and extracts from focus group interviews, class reports and reflective journals. Results from the textual data offer research evidence of successful curriculum change, demonstrating that the learning that takes place there can make a difference: in terms of the learners’ identity development, capability enhancement and cosmopolitan citizenship.
Full Text Available Both the appeal to some universal ethics and the evocation of a global civil society constitute the core of the "cosmopolitan democracies" theories, presented as either reality data or political desideratum. The paper aims at showing that in the terms formulated by the cosmopolitan democrats both ideas rely on evolutionist presuppositions. Institutions, values, and cultural ways of life effective on societies situated in the northern hemisphere end up being regarded as both per se superior and models for general application. Against such reorganization of the world, the paper indicatively cites necessary precautions in order to have both the international cooperation of social actors and the globalisation of human rights contribute towards overcoming particularisms in the several regions, taking into consideration, at the same time, the cultural particularities of the different regional contexts.

Full Text Available The implementation of democracy intensified since the fall of the new order era has some failures. One of the factors is violence phenomena still continue in the region. This study aims to discuss the violence in the region by presenting cosmopolitan democracy as a new design of more humane democracy. In addition, this research method uses library research, because library research can understand the problem in-depth to find the pattern and recommendation from the violence problems which happens in Indonesia. This study uses Hannah Arendt observations on the phenomenon of violence. In addition, the concept of cosmopolitan democracy is referred from Daniele Archibugi, David Held, and Ulrich Beck is presented as a draft of new democracy direction which is more inclusive and humane. The result of this study discloses that the occurrence of incidence is triggered by failed implementation of the democratic system in Indonesia.

Changing demographics, globalization, and an increasingly complex health care system demands progressive approaches to reaching our goals of competent transcultural care. Despite original contributions made by pioneers in cultural appreciation, nursing curricula are still falling short in addressing these issues in both education and practice. Many nurses enter their fields with little knowledge of the societal injustices and educational inequities that haunt the populations they care for. A cosmopolitan approach to nursing education is proposed to assist students in recognizing the complexity and uniqueness of individual experiences, rather than merely attempting to place them into categories based on gender, culture, race, or age. Being a global citizen and a cosmopolitan nurse requires participation in, and valuing of, the common good of society as a whole. Practicing the profession outside of comfort zones can lead to an appreciation for how all our choices are part of a complex global network. Nursing education should be responsible for developing in students the deepest knowledge base as well as the highest degree of critical independence. Cosmopolitan nurses could be the model for 21st century practitioners and future nurse leaders.
Full Text Available This is a preliminary argument of a much larger research project inquiring into the relation betweenHegel’s philosophical system and the project of emancipation in Critical International Relations Theory. Specifically, the paper examines how Hegel’s theory of recognition gestures towards a form of radical cosmopolitanism in world politics to ensure the conditions of rational freedom for all humankind. Much of the paper is a ground-clearing exercise defining what is ‘living’ in Hegel’s thought for emancipatory approaches in world politics, to borrow from Croce’s now famous question. It focuses on Hegel’s unique concept of freedom which places recognition as central in the formation of self-consciousness and therefore as a key determinant in the conditions necessary forhuman freedom to emerge in political community. While further research is needed to ascertain the precise relationship between Hegel’s recognition theoretic, emancipation and cosmopolitanism, it is contended that the intersubjective basis of Hegel’s concept of freedom through recognition necessitates some form of radical cosmopolitanism that ensures successful processes of recognition between all peoples, the precise institutional form of which remains unspecified.
Ethical cosmopolitanism has been the subject of substantial theoretical elaboration over its long history. However, until recently, very little attention had been given to the question of how individuals might be encouraged to behave as cosmopolitans in practice. Political theorists have recently identified a small number of factors – including certain social identities, collective guilt, and prosocial norms – that may increase cosmopolitan behaviour, but whether those factors actually do inc...

Production of titanium-dioxide nanomaterials (nano-TiO2) is increasing, leading to potential risks associated with unintended release of these materials into aquatic ecosystems. We investigated the acute effects of nano-TiO2 on metabolic activity and viability of algae and cyanobacteria using high-throughput screening. The responses of three diatoms (Surirella angusta, Cocconeis placentula, Achnanthidium lanceolatum), one green alga (Scenedesmus quadricauda), and three cyanobacteria (Microcystis aeruginosa, Gloeocapsa sp., Synechococcus cedrorum) to short-term exposure (15 to 60 min) to a common nano-TiO2 pigment (PW6; average crystallite size 81.5 nm) with simulated solar illumination were assessed. Five concentrations of nano-TiO2 (0.5, 2.5, 5, 10, and 25 mg L-1) were tested and a fluorescent reporter (fluorescein diacetate) was used to assess metabolic activity. Algae were sensitive to nano-TiO2, with all showing decreased metabolic activity after 30-min exposure to the lowest tested concentration. Microscopic observation of algae revealed increased abundance of dead cells with nano-TiO2 exposure. Cyanobacteria were less sensitive to nano-TiO2 than algae, with Gloeocapsa showing no significant decrease in activity with nano-TiO2 exposure and Synechococcus showing an increase in activity. These results suggest that nanomaterial contamination has the potential to alter the distribution of phototrophic microbial taxa within freshwater ecosystems. The higher resistance of cyanobacteria could have significant implications as cyanobacteria represent a less nutritious food source for higher trophic levels and some cyanobacteria can produce toxins and contribute to harmful algal blooms.

The Baas Becking tenet posits that 'everything is everywhere, but the environment selects' to explain cosmopolitan distributions in highly vagile taxa. Bryophyte species show wider distributions than vascular plants and include examples of truly cosmopolitan ranges, which have been interpreted as a result of high dispersal capacities and ecological plasticity. In the current study, we documented patterns of genetic structure and diversity in the cosmopolitan moss Bryum argenteum along an elevational gradient to determine if genetic diversity and structure is homogenized by intense migrations in the lack of ecological differentiation. • 60 specimens were collected in the Sierra Nevada Mountains (Spain) between 100 and 2870 m and sequenced for ITS and rps4. Comparative analyses, genetic diversity estimators, and Mantel's tests were employed to determine the relationship between genetic variation, elevation, and geographic distance and to look for signs of demographic shifts. • Genetic diversity peaked above 1900 m and no signs of demographic shifts were detected at any elevation. There was a strong phylogenetic component in elevational variation. Genetic variation was significantly correlated with elevation, but not with geographic distance. • The results point to the long-term persistence of Bryum argenteum in a range that was glaciated during the Late Pleistocene. Evidence for an environmentally driven pattern of genetic differentiation suggests adaptive divergence. This supports the Baas Becking tenet and indicates that ecological specialization might play a key role in explaining patterns of genetic structure in cosmopolitan mosses.

People with independent (vs. interdependent) social orientation place greater priority on personal success, autonomy, and novel experiences over maintaining ties to their communities of origin. Accordingly, an independent orientation should be linked to a motivational proclivity to move to places that offer economic opportunities, freedom, and diversity. Such places are cities that can be called "cosmopolitan." In support of this hypothesis, Study 1 found that independently oriented young adults showed a preference to move to cosmopolitan rather than noncosmopolitan cities. Study 2 used a priming manipulation and demonstrated a causal impact of independence on residential preferences for cosmopolitan cities. Study 3 established ecological validity by showing that students who actually moved to a cosmopolitan city were more independent than those who either moved to a noncosmopolitan city or never moved. Taken together, the findings illuminate the role of cosmopolitan settlement in the contemporary cultural change toward independence and have implications for urban development and economic growth.

Full Text Available BACKGROUND: Migratory animals comprise a significant portion of biodiversity worldwide with annual investment for their conservation exceeding several billion dollars. Designing effective conservation plans presents enormous challenges. Migratory species are influenced by multiple events across land and sea-regions that are often separated by thousands of kilometres and span international borders. To date, conservation strategies for migratory species fail to take into account how migratory animals are spatially connected between different periods of the annual cycle (i.e. migratory connectivity bringing into question the utility and efficiency of current conservation efforts. METHODOLOGY/PRINCIPAL FINDINGS: Here, we report the first framework for determining an optimal conservation strategy for a migratory species. Employing a decision theoretic approach using dynamic optimization, we address the problem of how to allocate resources for habitat conservation for a Neotropical-Nearctic migratory bird, the American redstart Setophaga ruticilla, whose winter habitat is under threat. Our first conservation strategy used the acquisition of winter habitat based on land cost, relative bird density, and the rate of habitat loss to maximize the abundance of birds on the wintering grounds. Our second strategy maximized bird abundance across the entire range of the species by adding the constraint of maintaining a minimum percentage of birds within each breeding region in North America using information on migratory connectivity as estimated from stable-hydrogen isotopes in feathers. We show that failure to take into account migratory connectivity may doom some regional populations to extinction, whereas including information on migratory connectivity results in the protection of the species across its entire range. CONCLUSIONS/SIGNIFICANCE: We demonstrate that conservation strategies for migratory animals depend critically upon two factors: knowledge of
Full Text Available In this article, we acknowledge the transformative nature of cogenerative dialogues and focus on the ethical dimension of the practice in order to move educational research, classrooms and schools beyond the current conceptions of what is ethical. Utilizing a fusion of the Belmont Report with nuanced notions of fourth generation evaluation procedures, we root cogenerative dialogues in a philosophical approach to cosmopolitanism that acknowledges the differences between multiple participants, multiple fields, and varying ways of knowing and being. Firstly, we consider how rooting the character of the truly ethical research act in a cosmopolitan ideal can attain participant beneficence. Secondly, we consider how to avoid the potential pitfalls of authenticity criteria in the practice of cogenerative dialogues by enacting practices that maximize tactical authenticity. Our approach to cogenerative dialogues serves as a method for critique and analysis that challenges our current practice and considers the ethics of cogenerative dialogues in inner city schools in a new light.

Full Text Available What is the nature of information? What is its role in Contemporary Cosmopolitan Civil Society? What is the basis for the widespread current belief that we live in an ‘information society’? The present article will examine these questions through an examination of the historical origins of established ‘scientized’ views of information in the philosophy of the Enlightenment. It describes how postmodern and poststructuralist critique of such positivist approaches led to profound paradigmatic and methodological shifts in the social and information studies fields in recent decades. It consider how the emergence of social constructivist approaches to information research drawing on discourse analysis, practice theory and ethnographic theories and methodologies has led to a have led researchers to a radically different understanding of central concepts such as: the influence of emergent information and communication technologies on contemporary society; the relationship between knowledge and power, the nature of expertise and authoritative information; a re-thinking of community and consensus; a re-interpretation of notions of space and place in information dissemination, sharing and use and a reconsideration of the role of the researcher. The article illustrates this changing research landscape through reference to the work of scholars in the Cosmopolitan Civil Societies Research Centre at the University of Technology, Sydney, published in the Centre’s journal.

cosmopolitanism to account for the kind of cosmopolitanism which characterizes this new cycle. Being dialogic entails connectivity between previous and forthcoming struggles in a process combining determination and anticipation with the constant (re)definition of the movement. This process is considered...... to be the combination of social local ruptures with global openness. Dialogic cosmopolitanism consists of 3 main features: the conflictual dimension, whereby the dominant consensus is questioned and spaces of conflict and dissent are generated; the shaping of translocal solidarities that are able to connect local...
Cosmopolitanism has been described as the cultural habitus of globalisation. It is therefore, albeit defined somewhat loosely, often associated with ethnically diverse, global cities. This paper considers the extent to which London engenders cosmopolitan values amongst its residents. It draws on survey data from the LOCAL MULTIDEM study of minorities' political participation to address these themes. The analysis examines perceptions of respect, belonging and geographical imaginaries - amongst established minorities and the ethnic majority - in north London. It is argued that cosmopolitan ethics are transformative and dialectical and, critically, cannot remain the preserve of the privileged in multi-ethnic neighbourhoods. The analysis presented demonstrates that a sense of belonging and cosmopolitan imaginaries are not evenly accessed by different ethnic groups; notably, that Bangladeshi Londoners who are born and bred in the city are less likely to appropriate these discourses than Caribbean, Indian or White residents.

Full Text Available This essay proposes cosmopolitan entanglement as a conceptual framework for the understanding of the Philippine pista (fiesta. The pista is a cosmopolitan phenomenon because communities engage in a disposition of cultural openness with the strange and the stranger. It is a performance of entanglement because it is a complex cultural phenomenon projected to be solemn yet secular, a festivity that neither the State nor the Church is in an ultimate position of authority, a parade of divinity, and a procession of spectacle. In arguing for cosmopolitan entanglement in the pista, the essay explores the 2007 Agawan festivity in Sariaya, Quezon, some 120 km south of Manila, as a case study. The first part is a conceptualization of cosmopolitanism as related to the pista using the Catholic dogma as lens. The analysis of Catholic dogma is necessary because in the Philippines the pista has its origin in Catholicism, its celebrations often coinciding with the feast day of a community’s patron saint. The second part examines the pista as a performance of entanglement. The final section describes the Sariaya pista via the Agawan festival as a case of cosmopolitan entanglement. The pista in Sariaya is an exemplar of cosmopolitan entanglement because community members perform cultural openness, which is also a mixing and matching of different performance activities, a strategy of combining the secular and the sacred, and a welcoming gesture to both the familiar and the stranger.

Large oceanic migrants play important roles in ecosystems, yet many species are of conservation concern as a result of anthropogenic threats, of which incidental capture by fisheries is frequently identified. The last large populations of the leatherback turtle, Dermochelys coriacea, occur in the Atlantic Ocean, but interactions with industrial fisheries could jeopardize recent positive population trends, making bycatch mitigation a priority. Here, we perform the first pan-Atlantic analysis of spatio-temporal distribution of the leatherback turtle and ascertain overlap with longline fishing effort. Data suggest that the Atlantic probably consists of two regional management units: northern and southern (the latter including turtles breeding in South Africa). Although turtles and fisheries show highly diverse distributions, we highlight nine areas of high susceptibility to potential bycatch (four in the northern Atlantic and five in the southern/equatorial Atlantic) that are worthy of further targeted investigation and mitigation. These are reinforced by reports of leatherback bycatch at eight of these sites. International collaborative efforts are needed, especially from nations hosting regions where susceptibility to bycatch is likely to be high within their exclusive economic zone (northern Atlantic: Cape Verde, Gambia, Guinea Bissau, Mauritania, Senegal, Spain, USA and Western Sahara; southern Atlantic: Angola, Brazil, Namibia and UK) and from nations fishing in these high-susceptibility areas, including those located in international waters.

Full Text Available Phylogeographic patterns and population structure of the pelagic Indian mackerel, Rastrelliger kanagurta were examined in 23 populations collected from the Indonesian-Malaysian Archipelago (IMA and the West Indian Ocean (WIO. Despite the vast expanse of the IMA and neighbouring seas, no evidence for geographical structure was evident. An indication that R. kanagurta populations across this region are essentially panmictic. This study also revealed that historical isolation was insufficient for R. kanagurta to attain migration drift equilibrium. Two distinct subpopulations were detected between the WIO and the IMA (and adjacent populations; interpopulation genetic variation was high. A plausible explanation for the genetic differentiation observed between the IMA and WIO regions suggest historical isolation as a result of fluctuations in sea levels during the late Pleistocene. This occurrence resulted in the evolution of a phylogeographic break for this species to the north of the Andaman Sea.

China is one among many other countries that have recognised the necessity in aligning national scientific progress with that of global development. As China is striding along the path of scientific development with determination and initial success, a key concern confronted by international scientific community is how China, a rising scientific power, will transform existing global scientific atlas. Based on a project carried out in six Chinese cities between 2006 to 2009, this paper mainly employs Ulrich Beck's cosmopolitan theory in examining China's life sciences' development in the last decade to investigate how Chinese stakeholders have developed a (cosmopolitan) sensibility to rival ways of scientific reasoning, and in what way, Chinese stakeholders have contributed to the cosmopolitanization of science.
Full Text Available Certain strands of cosmopolitanism have been criticized on various occasions for merely mirroring the mental framework of a global elite that stresses positive attitudes to mobility, flexibility, and disinterested objective detachment to the detriment of ‘rooted’, local and national values. In this way, it is argued, it presents a one-sided opportunistic or naively affirmative picture of processes of globalization rather than taking seriously the challenges posed by the inherently normative dimension of cosmopolitan thought and practice. The present paper will argue for a return to the critical core of the cosmopolitan idea and proposes that the critique of reification, which recently received renewed interest by philosophers of the so-called third generation Frankfurt School, can serve as a vital tool for re-imagining cosmopolitan teacher education as critique. In particular, the discussion around the recent turn towards a standards and competencies oriented teacher education in Germany will be critically examined in this regard. Rather than presenting a mere factual description of our thinking, judgments and actions, a cosmopolitan orientation should be concerned with reminding us of the importance of a continuous critical challenge of their validity. Firstly, the concept of reification will be shown to provide the conceptual resources to describe and select relevant characteristics of contemporary social pathologies that cannot be adequately captured within liberal social philosophies. A closer analysis of reification as a deficient relation to oneself, to others, or to the world will then lead to the second question of how to conceive of non-reifying forms of relatedness, commitment and boundedness as enabling new forms of expressive freedom. Instead of one-sided, narrow and hasty reactions towards a perceived ‘global challenge’—either fetishizing borders or their transgression, an critical educational cosmopolitanism should bring
Full Text Available This paper shows an alternative way in which compatriot partiality could be justified within the framework of global distributive justice. Philosophers who argue that compatriot partiality is similar to racial partiality capture something correct about compatriot partiality. However, the analogy should not lead us to comprehensively reject compatriot partiality. We can justify compatriot partiality on the same grounds that liberation movements and affirmative action have been justified. Hence, given cosmopolitan demands of justice, special consideration for the economic well-being of your nation as a whole is justified if and only if the country it identifies is an oppressed developing nation in an unjust global order.This justification is incomplete. We also need to say why Person A, qua national of Country A, is justified in helping her compatriots in Country A over similarly or slightly more oppressed non-compatriots in Country B. I argue that Person A’s partiality towards her compatriots admits further vindication because it is part of an oppressed group’s project of self-emancipation, which is preferable to paternalistic emancipation.Finally, I identify three benefits in my justification for compatriot partiality. First, I do not offer a blanket justification for all forms of compatriot partiality. Partiality between members of oppressed groups is only a temporary effective measure designed to level an unlevel playing field. Second, because history attests that sovereign republics could arise as a collective response to colonial oppression, justifying compatriot partiality on the grounds that I have identified is conducive to the development of sovereignty and even democracy in poor countries, thereby avoiding problems of infringement that many humanitarian poverty alleviation efforts encounter. Finally, my justification for compatriot partiality complies with the implicit cosmopolitan commitment to the realizability of global justice
Full Text Available Synch is an electronic music festival that takes place in Athens every summer and brings together people of various cultural origins and musical and aesthetic interests. As a total performance event, Synch becomes a site of complexity, polyvocality and hybridity; a site which allows participants to create and express cosmopolitan attitudes of openness for others, people, ideas and experiences. Adopting an anthropological/ethnographic perspective, this paper moves beyond distinctions between elite vs. ordinary and consumer vs. ethical cosmopolitanism, and investigates Synch as a site where local and trans-local aspects of life and a set of socio-cultural meanings in Greece today are being negotiated.

The author examines patterns of internal and international migration in western Mexico. "Drawing on data from different sources and statistics, the essay demonstrates the importance of both types of migration, the changes in endogenous and exogenous factors which have affected the life and the migratory patterns of the population of this region. The migratory circuit being a flow not only of persons, but of goods and capital as well, the cities, specifically that of Guadalajara, have a strategic importance. They fulfill various functions and have become the backbone of the migratory process: they serve as centers for attracting and 'hosting' internal migrants as well as places of origin for other migrants; jumping-off points for international migrants; and the milieu in which many returning migrants of rural origin settle."

It is commonly perceived that the 'globalization of science' may result in a 'Westernization of science'. In this paper, however, I use the case of stem cell science in China to demonstrate that developing countries are sometimes able to effectively shape the norms of global/local scientific exchange. Based on interviews with 38 stem cell scientists in six Chinese cities in early 2008, this paper elucidates Chinese scientists' outlook towards cross-border collaborations and the effects that the internationalization of science has had on everyday laboratory operations. Findings suggest that although there still exists an asymmetry of scientific influence, and in many aspects China is still 'catching-up' to the West, there is also a changing nature of communication beyond borders. One key aspect of recent international scientific development is the growing necessity for local stakeholders to acquire a global mindset and to compare, reflect and accommodate diverse interests. This is what I define as the 'cosmopolitanization of science'. The study empirically examines the sociological and methodological implications of the cosmopolitanization process and further develops Ulrich Beck's cosmopolitan theory by delineating four main features of the 'cosmopolitanization of science': shared future benefits, passive ethicization, reflexive negotiation, and continuous performance.

The Cosmopolitan Chicken Project is an artistic undertaking of renowned artist Koen Vanmechelen. In this project, the artist interbreeds domestic chickens from different countries aiming at the creation of a true Cosmopolitan Chicken as a symbol for global diversity. The unifying theme is the chicken and the egg, symbols that link scientific, political, philosophical and ethical issues. The Cosmopolitan Chicken Research Project is the scientific component of this artwork. Based on state of the art genomic techniques, the project studies the effect of the crossing of chickens on the genetic diversity. Also, this research is potentially applicable to the human population. The setup of the CC®P is quite different from traditional breeding experiments: starting from the crossbreed of two purebred chickens (Mechelse Koekoek x Poule de Bresse), every generation is crossed with a few animals from another breed. For 26 of these purebred and crossbred populations, genetic diversity was measured (1) under the assumption that populations were sufficiently large to maintain all informative SNP within a generation and (2) under the circumstances of the CCP breeding experiment. Under the first assumption, a steady increase in genetic diversity was witnessed over the consecutive generations, thus indeed indicating the creation of a "Cosmopolitan Chicken Genome". However, under the conditions of the CCP, which reflects the reality within the human population, diversity is seen to fluctuate within given boundaries instead of steadily increasing. A reflection on this might be that this is because, in humans, an evolutionary optimum in genetic diversity is reached. Key words.

It is frequently argued that classical sociology, if not sociology as a whole, cannot provide any significant insight into globalization, primarily because its assumptions about the nation-state, national cultures and national societies are no longer relevant to a global world. Sociology cannot consequently contribute to a normative debate about cosmopolitanism, which invites us to consider loyalties and identities that reach beyond the nation-state. My argument considers four principal topics. First, I defend the classical legacy by arguing that classical sociology involved the study of 'the social' not national societies. This argument is illustration by reference to Emile Durkheim and Talcott Parsons. Secondly, Durkheim specifically developed the notion of a cosmopolitan sociology to challenge the nationalist assumptions of his day. Thirdly, I attempt to develop a critical version of Max Weber's verstehende soziologie to consider the conditions for critical recognition theory in sociology as a necessary precondition of cosmopolitanism. Finally, I consider the limitations of some contemporary versions of global sociology in the example of 'flexible citizenship' to provide an empirical case study of the limitations of globalization processes and 'sociology beyond society'. While many institutions have become global, some cannot make this transition. Hence, we should consider the limitations on as well as the opportunities for cosmopolitan sociology.

Comparative phylogeography of widespread species that span the same geographic areas can elucidate the influence of historical events on current patterns of biodiversity, identify patterns of co-vicariance, and therefore aid the understanding of general evolutionary processes. Soil-dwelling animals present characteristics that make them suitable for testing the effect of the palaeogeographical events on their distribution and diversification, such as their low vagility and population structure. In this study, we shed light on the spatial lineage diversification and cladogenesis of two widely-distributed cosmopolitan and invasive earthworms (Aporrectodea rosea and A. trapezoides) in their putative ancestral area of origin, the Western Palearctic, and a few populations in North America. Molecular analyses were conducted on mitochondrial and nuclear markers from 220 (A. rosea) and 198 (A. trapezoides) individuals collected in 56 and 57 localities, respectively. We compared the lineage diversification pattern, genetic variability and cladogenesis in both species. Our findings showed that both species underwent a similar diversification from the Western Mediterranean plates to (i) Northern Europe and (ii) the Iberian Peninsula, establishing their two main lineages. Their diversification was in concordance with the main palaeogeographical events in the Iberian Peninsula and Western Mediterranean, followed by a later colonization of North America from individuals derived exclusively from the Eurosiberian lineage. Their diversification occurred at different times, with the diversification of A. rosea being potentially more ancient. Cladogenesis in both species seems to have been modelled only by the Mediterranean plate shifts, ignoring historical climatic oscillations such as the Messinian salinity crisis. Their high genetic variability, strong population structure, lack of gene flow and stepping-stone-like cladogenesis suggest the existence of different cryptic lineages
Full Text Available Child sex trafficking has become one of the most highly publicised social issues of our time and, due to its global nature, transnational anti-trafficking advocacy networks are well placed and central to lead campaigns against it. Whilst there is an abundance of literature on the subjects of child sex trafficking and transnational advocacy networks we lack an understanding of the motivations of these networks that act as buffers against trafficking. Cosmopolitan globalisation theory remains a compelling framework for examining the motivations of transnational anti-child sex trafficking networks in the Greater Mekong Subregion. Applying a cosmopolitan globalisation lens, this article discusses the social justice goals of transnational advocacy networks, their centrality in combating child sex trafficking, and their ability to perform cosmopolitan ‘globalisation from below’ to counter global social problems.

Full Text Available Since its publication in 1938 critics have generally read Xavier Herbert’s Capricornia as a nationalist novel, even when its nationalism is seen to be structured by contradiction. But little attention has been given to the ways in which Herbert’s complex, multifarious and heteroglossic novel exceeds and challenges the very possibility of coherent national space and a coherent national story. This essay considers moments and spaces in Herbert’s novel where the national is displaced and unravelled. Drawing on Rebecca Walkowitz’s idea of cosmopolitan style and Suvendrini Perera’s work on Australia’s insular imagination I identify a critical cosmopolitanism that inheres in the novel’s geographical imagination and its literary form, particularly the narrative voice which retains a critical distance from the nationalist sensibility of various characters and plot lines, performing a detached and restless homelessness that I identify with the cosmopolitan. Ultimately I ask how the novel’s spatial and environmental imagination displaces its nationalist agenda, making space for a different kind of social imagination—one that does not confine itself to the terms of the nation or organise itself around a central figure for the nation.

In earlier publications based on the research discussed in this article (e.g. Szerszynski and Urry 2002), we argued that an emergent culture of cosmopolitanism, refracted into different forms amongst different social groups, was being nurtured by a widespread 'banal globalism'--a proliferation of global symbols and narratives made available through the media and popular culture. In the current article we draw on this and other empirical research to explore the relationship between visuality, mobility and cosmopolitanism. First we describe the multiple forms of mobility that expand people's awareness of the wider world and their capacity to compare different places. We then chart the changing role that visuality has played in citizenship throughout history, noting that citizenship also involves a transformation of vision, an absenting from particular contexts and interests. We explore one particular version of that transformation--seeing the world from afar, especially in the form of images of the earth seen from space--noting how such images conventionally connote both power and alienation. We then draw on another research project, on place and vision, to argue that the shift to a cosmopolitan relationship with place means that humans increasingly inhabit their world only at a distance.

Colombia is important for migratory birds. Despite this, we do not know where they are during their crossing or residency in the country, and which species use paramo. We registered new migratory bird species for Laguna Del Otun, immersed in a complex of wetlands declared a Ramsar site since 2008. The lagoon is located in the Los Nevados National Natural Park at 3932 m asl, in paramo ecosystems of the Central Andes of Colombia. During five field trips between 2010-2012 we recorded four new migratory bird species for the park: Anas acuta, Pandion haliaetus, Riparia riparia, and Dendroica petechia. We also registered an altitudinal range extension for two additional migratory species which had only been recorded below 3500 m: Tringa flavipes and Hirundo rustica. These findings suggest these species could tolerate high mountain conditions and use the paramo. It's needed inquiry about migratory dynamics and high mountain habitat use by migratory birds.

Over 50% of western hemisphere shorebird species are in decline due to ongoing habitat loss and habitat degradation. Wetland dependent shorebirds prefer shallowly flooded habitats (water depth managed to optimize shallow areas. In-situ water depth measurements and microtopography data coupled with satellite image analysis can assist in understanding habitat suitability patterns at broad spatial scales. We generated detailed bathymetry, and estimated spatial daily water depths, the proportion of wetland area providing flooded habitat within the optimal depth range, and the volume of water present in 23 managed wetlands in the Sacramento Valley of California, a globally important shorebird stopover site. Using 30 years of satellite imagery, we estimated suitable habitat extent across the landscape under a range of climate conditions. While spring shorebird abundance has historically peaked in early April, we found that maximum optimal habitat extent occurred after mid-April. More than 50% of monitored wetlands provided limited optimal habitat (fleeting; only 4 wetlands provided at least 10 consecutive days with >5% optimal habitat during the peak of migration. Wetlands with a higher percent clay content and lower topographic variability were more likely to provide a greater extent and duration of suitable habitat. We estimated that even in a relatively wet El-Nino year as little as 0.01%, to 10.72% of managed herbaceous wetlands in the Sacramento Valley provided optimal habitat for shorebirds at the peak of migration in early April. In an extreme drought year, optimal habitat decreased by 80% compared to a wet year Changes in the timing of wetland irrigation and drawdown schedules and the design of future wetland restoration projects could increase the extent and duration of optimal flooded habitat for migratory shorebirds, without significant increases in overall water use requirements.

Full Text Available This study deals with the biogeography of Antarctic microflora (Antarctica acts as best model to study microbial biogeography such as cyanobacteria and selected halophiles with special emphasis on Halomonas variabilis and Bacillus licheniformis. Halophiles are known to be resistant not only to salt stress, but also to extreme temperature, pressure, and aridity and they are capable of surviving in harsh environments such as polar regions, deep-sea habitats, and deserts. Many microbes are known to be resistant to hostile environmental conditions, and are capable of surviving in harsh environments. Our group has isolated 444 strains belonging to 28 genera of halophiles from various environments around the world. The 16S rRNA gene sequences revealed that many of the isolated strains from geographically distant habitats having different environmental conditions, were closely related to each other, with some strains possessing 100% identical sequences. Organisms possessing survival mechanism such as spore formation are usually ubiquitous. The genus Halomonas is represented by potentially endemic strains and the ubiquitous H. variabilis, while spore-forming B. licheniformis showed cosmopolitan distribution. One potentially endemic (moderate endemicity that is regional and/or continental distribution strain was reported from Syowa station, East Antarctica, and Mario Zucchelli station, West Antarctica, which are geographically separated by 3000 km. Moreover, 15 strains having 100% similarity with B. licheniformis were considered cosmopolitans. The results of this work provide support for the middle-ground model that some microbes have moderate endemicity and others have cosmopolitan distribution. These results will contribute to a greater understanding of microbial biogeography with special emphasis on Antarctica.
Full Text Available This is a synaptic paper that invites the reader to take a stroll on the edges of cross-disciplinary knowledge. We will walk the roads of anthropology, history, philosophy, astronomy and biology. It is mainly a theoretical article, where I attempt to provide links between authors and theories that were, at first sight, unrelated. In doing so, this paper is aimed at making one controversial claim: ideologically and politically speaking, cosmopolitanism may never fully transcend itself beyond a debate until and unless humankind encounters alien life forms. The argument is based on a simple equation. Despite all the quarrels and debates around the concept, it seems innocuous to assume that cosmopolitanism is the search for a certain universal identity or, at least, a search for a common culturalia, i.e. the cultural grounds wherein local and global senses of universalism come into being (section 2. In spite of the fact that identities are built in opposition and supported by difference (section 3, cosmopolitanism might only be possible as a political project (cosmopolitics when humankind is faced with life forms that are capable of providing true Otherness. I believe that this may explain why we have been fascinated by the utopias of extra-terrestrials for many centuries now (section 4. These utopias are present in a diverse array of knowledges, ranging from science to art, literature or even religion. They have been around for at least 500 years. Until now, all of them have been trapped in the realm of imagination, but there is one concrete cluster of knowledge that has attempted to transpose these imaginings into reality: the promising discipline of astrobiology. Astrobiology is mainly troubled by the de-naturalisation of Earth in order to create analogues for the study of life elsewhere in the cosmos. Provocatively, I end up this paper stating that this may well be the most cosmopolitical practice available to us (section 5.

Neuroethics applies cognitive neuroscience for prescribing alterations to conceptions of self and society, and for prescriptively judging the ethical applications of neurotechnologies. Plentiful normative premises are available to ground such prescriptivity, however prescriptive neuroethics may remain fragmented by social conventions, cultural ideologies, and ethical theories. Herein we offer that an objectively principled neuroethics for international relevance requires a new meta-ethics: understanding how morality works, and how humans manage and improve morality, as objectively based on the brain and social sciences. This new meta-ethics will simultaneously equip neuroethics for evaluating and revising older cultural ideologies and ethical theories, and direct neuroethics towards scientifically valid views of encultured humans intelligently managing moralities. Bypassing absolutism, cultural essentialisms, and unrealistic ethical philosophies, neuroethics arrives at a small set of principles about proper human flourishing that are more culturally inclusive and cosmopolitan in spirit. This cosmopolitanism in turn suggests augmentations to traditional medical ethics in the form of four principled guidelines for international consideration: empowerment, non-obsolescence, self-creativity, and citizenship.

Long-distance animal migrations have important consequences for infectious disease dynamics. In some cases, migration lowers pathogen transmission by removing infected individuals during strenuous journeys and allowing animals to periodically escape contaminated habitats. Human activities are now causing some migratory animals to travel shorter distances or form sedentary (non-migratory) populations. We focused on North American monarch butterflies and a specialist protozoan parasite to investigate how the loss of migratory behaviours affects pathogen spread and evolution. Each autumn, monarchs migrate from breeding grounds in the eastern US and Canada to wintering sites in central Mexico. However, some monarchs have become non-migratory and breed year-round on exotic milkweed in the southern US. We used field sampling, citizen science data and experimental inoculations to quantify infection prevalence and parasite virulence among migratory and sedentary populations. Infection prevalence was markedly higher among sedentary monarchs compared with migratory monarchs, indicating that diminished migration increases infection risk. Virulence differed among parasite strains but was similar between migratory and sedentary populations, potentially owing to high gene flow or insufficient time for evolutionary divergence. More broadly, our findings suggest that human activities that alter animal migrations can influence pathogen dynamics, with implications for wildlife conservation and future disease risks.

Full Text Available This study is focused on a cosmopolitan group of both famous and less famous radical intellectuals from both sides of the Atlantic—some of them of popular origin and self-educated—all linked by relations of personal friendship or at least col- laboration or contiguity: Thomas Paine, Joel Barlow, Nicolas de Bonneville, John Oswald, Joseph Ritson. The analysis of the language strategies they used to attempt a democratization of the universal communication that had been until then kept among the educated members of the Republic of letters—in particular insofar as the high tradition of the critique of revealed religion was concerned, considered here as an absolutely crucial point—centers on the themes of political etymology and of confidence in the performative energy of decoded words.

Background An oral condition associated to psoriasis is benign migratory glossitis. The review of the literature does not show any publication about heritability in both soriasis and benign migratory glossitis and prevalence of psoriasis in the Brazilian population. Objective This research was carried out in order to determine the prevalence of psoriasis and benign migratory glossitis in the Brazilian population from a Brazilian sample, as well as the heritability in these conditions. Methods Six thousand patients were studied from the records of the outpatient dermatology department. The sample had 129 patients with cutaneous psoriasis, 399 with benign migratory glossitis without psoriasis and a control group with 5,472 patients. After data collection, the statistical analysis was made using Woolf, Chi-square and Falconer tests. Results The prevalence of psoriasis was 2.15% and the benign migratory glossitis was 7.0%. The prevalence of benign migratory glossitis in the psoriasis group was high (16.3%), and that was statistically significant. Family history in the psoriasis group was 38% for the condition itself and 2,75% for benign migratory glossitis and in the benign migratory glossitis group was 17.54% for the condition itself and 1.5% for psoriasis. The study of heritability was 38.8% for psoriasis and 36.6% for benign migratory glossitis, both with medium heritability. Study limitations This study was only in the state of São Paulo. Conclusion This is the first publication that quantifies how much of these conditions have a genetic background and how important the environmental factors are in triggering them. PMID:29364438

The theme of this special issue is the necessity of a cosmopolitan turn in social and political theory. The question at the heart of this introductory chapter takes the challenge of 'methodological cosmopolitanism', already addressed in a Special Issue on Cosmopolitan Sociology in this journal (Beck and Sznaider 2006), an important step further: How can social and political theory be opened up, theoretically as well as methodologically and normatively, to a historically new, entangled Modernity which threatens its own foundations? How can it account for the fundamental fragility, the mutability of societal dynamics (of unintended side effects, domination and power), shaped by the globalization of capital and risks at the beginning of the twenty-first century? What theoretical and methodological problems arise and how can they be addressed in empirical research? In the following, we will develop this 'cosmopolitan turn' in four steps: firstly, we present the major conceptual tools for a theory of cosmopolitan modernities; secondly, we de-construct Western modernity by using examples taken from research on individualization and risk; thirdly, we address the key problem of methodological cosmopolitanism, namely the problem of defining the appropriate unit of analysis; and finally,we discuss normative questions, perspectives, and dilemmas of a theory of cosmopolitan modernities, in particular problems of political agency and prospects of political realization.
The body of work presented in this dissertation is a response to the reported association between poor outcomes in science achievement and students of color in urban schools. By presenting counterexamples to the cultural motif that urban students of color perform poorly in science, I argue that poor achievement cannot be traced to a group of people but can be linked to institutions promoting subject delivery methods that instill distaste for science and compel students to display an illusion of disinterest in school. There are two major goals of this study. First, I plan to demonstrate how plans of action generated by coteachers and cogenerative dialogue groups can coalesce under the ethos of making science and schooling accessible to populations that are traditionally marginalized from science achievement. My second aim is to develop mechanisms for transforming science learning contexts into cosmopolitan learning communities that develop student success in science. Through a three-year ethnographic study of physics and chemistry classrooms in a high school in New York City, I present explorations of the culture and context of the urban classroom as a chief means to meet my goals. In my research, I find that obstacles to identity development around science can be tied to corporate understandings of teaching and learning that are amenable to local efforts toward change. This change is facilitated through the use of transformative tools like cogenerative dialogues, coteaching, and cosmopolitanism. Through the application of these research tools, I uncover and investigate how various misalignments that present themselves in physics and chemistry classrooms serve as signifiers of macro issues that permeate science classrooms from larger fields. By utilizing cogenerative dialogues as a tool for investigating both micro enactments within classrooms and the macro structures that generate these enactments, I show how students and teachers can work together as co
Full Text Available In this article, I discuss teacher education reform and the work of teachers in light of globalization and reflexive modernization. Increasing globalization has meant changed conditions for national education traditionally geared toward nation building and to the nationalizing of lifeworlds. It is assumed that the global economy has made knowledge and lifelong learning essential to economic growth, and governments have considered their citizens, teachers, and schools to be poorly trained for the demands of knowledge economies. Consequently, nation-states have invested massively in teacher education because of the vital role effective high-quality teachers are expected to play in preparation for working on global markets and for the competitive edge of nations. However, recent teacher education reform can be criticized for a one-sided orientation toward principles of economic growth, effectiveness, and competitiveness at the expense of other important educational aims, such as the development of reflective and communicative capacities and education for cosmopolitan citizenship. Moreover, recent teacher education reform in various nation-states seems to neglect how processes of reflexive modernization profoundly change schools, society, and the teaching situation, and undermine the principles that marked earlier phases of nation-centered modernization. I discuss teacher education and the work of teachers as reflexive modern practices and phenomena within the framework of critical social theory, and I mainly use Ulrich Beck's theory of reflexive modernization. I argue that increased reflexivity, institutionalized individualization, and cosmopolitization constitute reasons for the re-contextualization of teacher education away from the uncritical influence of the primacy of the economy, instrumental rationalization, and other principles of modernization that are now running dry. In the final part, I discuss the importance of moving from a mainly
Full Text Available Spatial patterns of species diversity provide information about the mechanisms that regulate biodiversity and are important for setting conservation priorities. Present knowledge of the biogeography of meiofauna in the deep sea is scarce. This investigation focuses on the distribution of the deep-sea nematode genus Manganonema, which is typically extremely rare in deep-sea sediment samples. Forty-four specimens of eight different species of this genus were recorded from different Atlantic and Mediterranean regions. Four out of the eight species encountered are new to science. We report here that this genus is widespread both in the Atlantic and in the Mediterranean Sea. These new findings together with literature information indicate that Manganonema is a cosmopolitan genus, inhabiting a variety of deep-sea habitats and oceans. Manganonema shows the highest diversity at water depths >4,000 m. Our data, therefore, indicate that this is preferentially an abyssal genus that is able, at the same time, to colonize specific habitats at depths shallower than 1,000 m. The analysis of the distribution of the genus Manganonema indicates the presence of large differences in dispersal strategies among different species, ranging from locally endemic to cosmopolitan. Lacking meroplanktonic larvae and having limited dispersal ability due to their small size, it has been hypothesized that nematodes have limited dispersal potential. However, the investigated deep-sea nematodes were present across different oceans covering macro-scale distances. Among the possible explanations (hydrological conditions, geographical and geological pathways, long-term processes, specific historical events, their apparent preference of colonizing highly hydrodynamic systems, could suggest that these infaunal organisms are transported by means of deep-sea benthic storms and turbidity currents over long distances.

The species concept in marine phytoplankton has enormous biological complexity. Differences in genomic, morphological, physiological, biogeochemical, and ecological/biogeographic properties between strains of the same species can be comparable or even exceed those between species. This complexity is particularly pronounced in the cosmopolitan coccolithophore species Emiliania huxleyi. This bloom-forming species is found at nearly every latitude in a variety of environments including upwelling regions, and exposed to large temperature gradients. We present results from experiments using two strains of E. huxleyi isolated from different latitudes and environmental conditions. Tests involved semi-continuous culturing in lab manipulation experiments to determine how carbon fixation, growth, and morphology respond to temperature-driven alterations in physico-chemical conditions. This talk will discuss the observed differences in physiology within an ecological context and the implications of these biogeochemical differences in modeling carbon fluxes driven by phytoplankton.

Full Text Available Can human rights in education enhance students and teachers capacity to reimagine their local community and to rethink the rules and laws that support such a social community? This paper is a political philosophical inquiry into human rights in education, drawing on the work of Hannah Arendt, Cornelius Castoriadis and Adriana Cavarero. By placing learning at the center of political philosophy through the notion of paideia, we need to ask how such an education can look like. According to Castoriadis, society exists only insofar as it is embodied in its social individuals. Society and its individuals are in a constant process of becoming toward relational autonomy that implies a moral self-limitation. At the core of my philosophical inquiry into moral subjectification is the need to re-think human rights and the pedagogical subject in relational terms that imply self-limitation and political engagement in a wider cosmopolitan community

Using Showtime's The L Word as a case study, we argue that lesbian sexuality and lesbian lifestyles are produced alongside broader discourses of cosmopolitan consumer citizenship. The lesbian characters in this program are first and foremost constructed through their investments in certain neo-liberal consumer and lifestyle practices that limit the possibility of what lesbian subjectivities and/or lesbian politics can or cannot become. We offer an alternative strategy of reading lesbians in image-based media and popular culture that attends to the ways in which lesbian subjectivities are produced in a climate of neo-liberal consumer and lifestyle practices that have shifted the ways in which sexual citizens are produced. Our aim is to provide a critical framework that can be applied to other lesbian-themed television texts and to a range of other image-based visual media including film, commercial advertising, and new media.

Port Harcourt is a cosmopolitan city consisting of several ethnic groupings such as Ikwerre, Ijaw, Igbo, Ogonis, Efik-Ibibio, Edo, Yoruba, Hausa and foreign nationals. ABO and Rhesus D antigens were screened in this cross-sectional study with the aim of generating data that would assist in the running of an efficient blood transfusion service for a cosmopolitan city as Port Harcourt. Blood donors were sampled and screened for ABO and Rhesus D antigens at three Health facilities within Port Harcourt: University of Port Harcourt Teaching Hospital, Braithwaite Memorial Hospital and Orogbum Health centre. A total of 936 blood donors were tested in this study. The results of the ABO screening shows that blood group O was the highest with 527 (56.30%) followed by blood group A, B and lastly AB with 212 (22.65%), 178 (19.02%) and 18(2.10%) respectively. The highest contribution to blood group O was from the Ibos with 220 (23.50%) while the Ijaws gave the highest contribution of Rhesus "D" antigen with 370 (39.53%), closely followed by the Igbos with 334 (0.43%). Rhesus negativity values in this study was 7.26% of which the highest contributors were also the Ijaws with 33 (3.53%) and Igbos with 27(2.89%). The increased demand for safe blood calls for an efficient Blood, Transfusion Service at the local, state and national levels. It is hoped that the data generated in this study would assist in the planning and establishment of a functional Blood service that would not only meet the ever increasing demand for blood products, but also play a vital role in the control of HIV/AIDS and . Hepatitis B global scourge.
Full Text Available One of the most significant directions of the world-wide contemporary philosophy, phenomenology of life of Anna-Teresa Tymieniecka represents a major path of thinking and acting for the promotion of what does mean the universal valuable in human beingness by disclosing and unfolding an essential modality of understanding and shaping some paradigms of world culture. We face an original author and a reputed activist doing exceptional work to foster a culture of dialogue in the world. The impressive Tymienieckan philosophical work has imposed itself as a great contribution to the heralding of a “New Enlightenment” encompassing humanity in the endeavour of creating, maintaining and developing the wellbeing and the common good of mankind, in securing the human common destiny. Putting in act a holistic and dynamic philosophy upon life and human condition, phenomenology of life offers a viable pattern of communication between different cultures, of overcoming any kind of contradictions in dealing with the fundamental issues of living together and sharing-in-life. We can find elements for tackling and comprehending in a better way our cosmopolitan humanness, due to the opening of a creative approach of identity and otherness, by admitting differentiation and also by working for harmony in the play of life. Throughout new concepts and a very own complex vision of the respect for life, the philosophy-in-act of AnnaTeresa Tymieniecka manifests valences of an integrator enterprise in interpreting the cosmopolitan status of the philosopher in nowadays, in affirming the role of a responsible citizen of the world.

Full Text Available Artificial light at night is spreading worldwide at unprecedented rates, exposing strictly nocturnal animals such as bats to a novel anthropogenic stressor. Previous studies about the effect of artificial light on bats focused almost exclusively on non-migratory species, yet migratory animals such as birds are known to be largely affected by light pollution. Thus, we conducted a field experiment to evaluate if bat migration is affected by artificial light at night. In late summer, we presented artificial green light of 520 nm wavelength to bats that were migrating south along the shoreline of the Baltic Sea. Using a light on-off treatment, we observed that the activity of Pipistrellus nathusii and P. pygmaeus, the two most abundant migratory species at our site, increased by more than 50% in the light-on compared to the light-off treatment. We observed an increased number of feeding buzzes during the light-on compared to the light-off treatment for P. nathusii. However, feeding activity was low in general and did not increase disproportionately during the light-on treatment in relation to the overall echolocation call activity of bats. Further, P. nathusii were attracted towards the green light at a distance of about 23 m, which is way beyond the echolocation detection range for insects of Nathusius' bats. We therefore infer that migratory bats were not attracted to artificial green light because of high insect densities, but instead by positive phototaxis. We conclude that artificial light at night may potentially impact bat migration in a yet unrecognized way.
Full Text Available This article explores what motivates the movements of Chinese migrants from China to Portugal. It presents an ethnographic account of social aspirations in Wenzhou, a port city located in South Zhejiang (Southeast China, where post-Mao economic prosperity, allied to the existence of networks of trade and migration, resulted in social and economic inequalities and great social pressure to become rich and successful. Based on ethnographic fieldwork conducted in Wenzhou and in Lisbon (Portugal between 2008 and 2010, this paper argues that Wenzhou migratory projects are a result of modernity aspirations and desires for material modernization articulated with core Chinese values such as filial piety.
Full Text Available In a Europe of many lights and shadows, cosmopolitan sociology provides a valid theoretical framework to distinguish one from the other. If cosmopolitan sociology is an attempt to understand how individuals, social groups and institutions deal with the challenges of ever more transnational social processes, then the European issue can be fully inserted within such an approach. From this point of view, following the austerity policies and recent events involving Syrian refugees and the attack by Daesh activists at the heart of Europe, sociology has started to enquire whether a cosmopolitan Europe is still possible. Conversaly, in the history of Europe and in its Constitutional Treaties, traces of cosmopolitanism are to be found almost everywhere. In this context, our study examines the crisis pervading Europe today and highlights the standing back to a certain extent of cosmopolitan sociology. At the same time, it stresses the hope that a change of direction will occur and the opportunity grasped of reflecting more deeply on the founding principles of cosmopolitan Europe.

In 2008, a Dutch member of parliament released a short anti-Islamic film entitled Fitna, which stirred a huge public controversy and provoked public condemnations around the world. In response to the film, hundreds of videos were uploaded on YouTube, mostly with the aim to provide a more positive representation of Islam, express support for the author and his views, or defend his freedom of speech. Drawing on interviews with YouTube users who posted the videos, this paper reflects on the capacity of the Internet to sustain cosmopolitan communication and examines how cosmopolitan attitudes and practices on-line differ depending on the participants' cultural and social background, especially their religious affiliations. Particular attention is paid to how the opportunities for cosmopolitan communication are shaped by the unequal distribution of cosmopolitan attitudes and practices among groups, and by global inequalities of power. In addressing these issues, the paper also engages with broader debates about cosmopolitanism, and argues for an understanding of cosmopolitanism as a quest for universalism, which remains anchored in the particular, but involves communication across difference, and requires openness to the possibility that the other is right. © London School of Economics and Political Science 2011.

Long-distance migration is a strategy some animals use to survive a seasonally changing environment. To reach favorable grounds, migratory animals have evolved sophisticated navigational mechanisms that rely on a map and compasses. In migratory insects, the existence of a map sense (sense of position) remains poorly understood, but recent work has provided new insights into the mechanisms some compasses use for maintaining a constant bearing during long-distance navigation. The best-studied directional strategy relies on a time-compensated sun compass, used by diurnal insects, for which neural circuits have begun to be delineated. Yet, a growing body of evidence suggests that migratory insects may also rely on other compasses that use night sky cues or the Earth's magnetic field. Those mechanisms are ripe for exploration.

Full Text Available In 2004 Hollywood produced three purportedly blockbuster epic films:Troy, King Arthur and Alexander. Many critics suggested a direct linkbetween the 1950s “sword and sandal” epic and this new crop of movies.Similarities between the two cycles certainly exist but in this essay I want to emphasize a crucial difference between the contemporary,cosmopolitan, epic and the previous, more nation-bound, 1950s cycle.Rather than being in tune with key elements of American foreign policy, the new cycle of “sword and sandal” films offers a somber assessment of American imperial adventures. I shall contend, in fact, that the new crop of epic films had to choose between two generic conventions that are, at present, not compatible. On the one hand, epic films had traditionally been the bearers of the foreign policy vision of the country that produced them. On the other, their inflated budgets made them dependent on an international market. Deeply aware of a globalized and rising opposition to US foreign policy and of the fact that foreign box office now exceeds the domestic take of a blockbuster, it may be no wonder that the makers of these films chose to craft them into citizens of the world.

Understanding the behaviour of animals in the wild is fundamental to conservation efforts. Advances in bio-logging technologies have offered insights into the behaviour of animals during foraging, migration and social interaction. However, broader application of these systems has been limited by device mass, cost and longevity. Here, we use information from multiple logger types to predict individual behaviour in a highly pelagic, migratory seabird, the Manx Shearwater (Puffinus puffinus). Using behavioural states resolved from GPS tracking of foraging during the breeding season, we demonstrate that individual behaviours can be accurately predicted during multi-year migrations from low cost, lightweight, salt-water immersion devices. This reveals a complex pattern of migratory stopovers: some involving high proportions of foraging, and others of rest behaviour. We use this technique to examine three consecutive years of global migrations, revealing the prominence of foraging behaviour during migration and the importance of highly productive waters during migratory stopover.

Mass extinctions have profoundly impacted the evolution of life through not only reducing taxonomic diversity but also reshaping ecosystems and biogeographic patterns. In particular, they are considered to have driven increased biogeographic cosmopolitanism, but quantitative tests of this hypothesis are rare and have not explicitly incorporated information on evolutionary relationships. Here we quantify faunal cosmopolitanism using a phylogenetic network approach for 891 terrestrial vertebrate species spanning the late Permian through Early Jurassic. This key interval witnessed the Permian-Triassic and Triassic-Jurassic mass extinctions, the onset of fragmentation of the supercontinent Pangaea, and the origins of dinosaurs and many modern vertebrate groups. Our results recover significant increases in global faunal cosmopolitanism following both mass extinctions, driven mainly by new, widespread taxa, leading to homogenous 'disaster faunas'. Cosmopolitanism subsequently declines in post-recovery communities. These shared patterns in both biotic crises suggest that mass extinctions have predictable influences on animal distribution and may shed light on biodiversity loss in extant ecosystems.Mass extinctions are thought to produce 'disaster faunas', communities dominated by a small number of widespread species. Here, Button et al. develop a phylogenetic network approach to test this hypothesis and find that mass extinctions did increase faunal cosmopolitanism across Pangaea during the late Palaeozoic and early Mesozoic.

Full Text Available This study aimed to find out how cosmopolitanism influences the destination image building. To accomplish this objective we interviewed foreign people, who know São Paulo, a city with national and international importance, due to its structure, economy, size, population and by its intense cultural and business life. This work reviewed cosmopolitanism that is the desire to know other cultures, besides his native one. This leads to an intention to travel through different regions, countries, to deepen in other societies and try to blend into it. Thus, one has particular characteristics, which influence the way one lives and consume products. The destination image can be defined as the sum of beliefs, ideas and impressions that a person has about a destination. To understand how cosmopolitanism influences the destination image, two approaches were used. A qualitative approach used interviews with professionals from SPTuris, as well as personal interviews with foreign tourists at the airport., This data was analyzed using content analysis. The quantitative approach included a survey with 205 foreigners. Data was analyzed using univariate and multivariate statistics, ANOVA and structural equation modeling. The result showed that cosmopolitanism and income influences the affective aspect in the destination image formation. It also showed that the stay purpose influenced the cognitive aspect, and that the length of stay influenced both aspects of the destination image.

Full Text Available We residents of Samarkand and Bukhara, throughout history aimed to accumulate traditions of challenging the established (often elitist limits of local culture, economics and history. The cities communities were under constant pressure of the dichotomy between the notions of nomadism and sedentism, Turkic and Persian speakers. Many community-based units of Samarkand had their own commercial, socio-cultural and educational networks that preserved alternativeness within the life cycle, which balanced between universality and particularism. These lands were dominated by a unique parity, based on Sufi ethics, which designed not syncretic cosmopolitism, but rather introduced the recognition of alternativeness that took into account both similar and diverse waves of ideas. Based on this vision, the author aims to diminish Kantian cosmopolitanism to a level of Euro-American and illustrate the view of cosmopolitanism through a dialogic platform, precisely including its links with the Central Asian versions. Moreover, one cannot identify local cosmopolitanism with the ideas of European Enlightenment, namely individualism and universalism on a global scale. Due to the alternativeness and cosmopolitanism, as well as lack of radical individualism within the local communities, there was no monocultural view on life, since both science and morality (religion, culture, and community were mutually essential. Nonetheless, present proves that these fields remain their equal vitality to an individual who is capable of simultaneously possessing knowledge about the reality and receiving satisfaction from the reality. This constant motion based on reciprocation was maintained in the ancient culture of Samarkand by two factors: cosmopolitanism and alternativeness.

Full Text Available Cosmopolitanism, desire and the contracting of social relationships are enduring themes in both philosophy and social theory. In this paper I seek to explore these themes in order to ascertain what they might mean to disabled people and the ethos of ableism more generally. Modern Westernized life has since the Industrial Revolution been sited in cities fostering the growth of urban culture and an ethos of cosmopolitanism (Agamben, 2009; Beck, 2002; Cheah, 2006. The cosmopolitan outlook has become the signifier of that which is developed, advanced and civilized in society. The liberal project of the melting pot, of social tolerance is cast against the backdrop of city life (Brown, 2006. The paper will first examine the trope of cosmopolitanism and disability including the place of ‘spaces’ for marginal peoples. Second, it will provide a perspective on the disabled flâneur (Campbell, 2009; Simmel, 1908; Young, 2005 who ambivalently claims ‘outsider-insidedness’ and finally the paper moves to consider the significant question of social inclusion and the government of aversion through the deployment of discourses of tolerance. Keywords: cosmopolitanism; social inclusion, community, flâneur, tolerance; biopolitics; disability

Full Text Available BACKGROUND: Sea turtles are long-distance migrants with considerable behavioural plasticity in terms of migratory patterns, habitat use and foraging sites within and among populations. However, for the most widely migrating turtle, the leatherback turtle Dermochelys coriacea, studies combining data from individuals of different populations are uncommon. Such studies are however critical to better understand intra- and inter-population variability and take it into account in the implementation of conservation strategies of this critically endangered species. Here, we investigated the movements and diving behaviour of 16 Atlantic leatherback turtles from three different nesting sites and one foraging site during their post-breeding migration to assess the potential determinants of intra- and inter-population variability in migratory patterns. METHODOLOGY/PRINCIPAL FINDINGS: Using satellite-derived behavioural and oceanographic data, we show that turtles used Temporary Residence Areas (TRAs distributed all around the Atlantic Ocean: 9 in the neritic domain and 13 in the oceanic domain. These TRAs did not share a common oceanographic determinant but on the contrary were associated with mesoscale surface oceanographic features of different types (i.e., altimetric features and/or surface chlorophyll a concentration. Conversely, turtles exhibited relatively similar horizontal and vertical behaviours when in TRAs (i.e., slow swimming velocity/sinuous path/shallow dives suggesting foraging activity in these productive regions. Migratory paths and TRAs distribution showed interesting similarities with the trajectories of passive satellite-tracked drifters, suggesting that the general dispersion pattern of adults from the nesting sites may reflect the extent of passive dispersion initially experienced by hatchlings. CONCLUSIONS/SIGNIFICANCE: Intra- and inter-population behavioural variability may therefore be linked with initial hatchling drift scenarios

The macrogeographic population structure of the agricultural pest Bactrocera cucurbitae (Diptera: Tephritidae) was investigated in order to identify the geographic origin of the species and reconstruct its range expansion. Individuals of B. cucurbitae were collected from 25 worldwide-distributed localities (n = 570) and genotyped at 13 microsatellite loci. The Bayesian clustering reveals that B. cucurbitae can be subdivided into five main groups corresponding to populations from (i) the African continent, (ii) La Réunion, (iii) Central Asia, (iv) East Asia and (v) Hawaii. The proportions of inter-regional assignments and the higher values of genetic diversity in populations from Pakistan, India and Bangladesh suggest that B. cucurbitae originated in Central Asia and expanded its range to East Asia and Hawaii on one hand and to Africa and the islands of the Indian Ocean on the other. A number of outliers (10-19 specimens according to different clustering algorithms) show high levels of admixture (Q > 0.70) with populations from different regions and reveal complex patterns of inter-regional gene flow. Anthropogenic transport is the most plausible promoter of this large-scale dispersal. The introduction of individuals from geographically distant sources did not have a relevant role in the most recent African invasions, which originated from the expansion of local populations. These results could provide a useful background to better evaluate invasion risks and establish priorities for the management of this cosmopolitan agricultural pest.

Accumulation features of persistent organochlorines in migratory birds from Asia did not necessarily reflect only the pollution in the sampling area. - Concentrations of organochlorine contaminants including polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane and its metabolites (DDTs), hexachlorocyclohexane isomers (HCHs), chlordane compounds (CHLs), hexachlorobenzene (HCB) were determined in the resident and migratory birds, which were collected from India, Japan, Philippines, Russia (Lake Baikal) and Vietnam. Accumulation patterns of organochlorine concentrations in resident birds suggested that the predominant contaminants of each country were as follows: Japan-PCBs Philippines-PCBs and CHLs, India-HCHs and DDTs, Vietnam-DDTs, and Lake Baikal-PCBs and DDTs. The migratory birds from Philippines and Vietnam retained mostly the highest concentrations of DDTs among the organochlorines analyzed, indicating the presence of stopover and breeding grounds of those birds in China and Russia. On the other hand, migratory birds from India and Lake Baikal showed different patterns of organochlorine residues, reflecting that each species has inherent migratory routes and thus has exposure to different contaminants. Species which have breeding grounds around the Red Sea and Persian Gulf showed high levels of PCBs, indicating the presence of areas heavily polluted by PCBs in the Middle East

Full Text Available We describe a case of acute liver injury and migratory arthralgia in a patient receiving bicalutamide treatment for prostate cancer. A 67-year-old male with metastatic prostate cancer presented with a 6-day history of migratory arthralgia. He had been undergoing treatment with bicalutamide for 4 months; 3 weeks prior to symptom appearance the bicalutamide dose had been increased. He had no other symptoms. Liver tests and inflammatory markers were markedly elevated. Serology for hepatitis viruses A, B, and C, CMV, and EBV and autoimmune causes were all negative, and an ultrasound of the upper abdomen was normal. There was no history of blood transfusion, intravenous drug abuse, or alcohol abuse. Due to the suspicion of a drug-induced symptomatology, bicalutamide was discontinued and the patient started on 30 mg prednisolone daily. Three weeks later he was symptom free and after 6 weeks his liver tests were almost normal. The Roussel Uclaf Causality Assessment Method (RUCAM suggested a high probability of liver injury. Bicalutamide has very rarely been reported as a causative agent for liver injury and to our knowledge never for migratory polyarthralgia. The migratory polyarthralgia was attributed to bicalutamide due to the absence of other etiological factors and the disappearance of symptoms after discontinuation of the drug. To our knowledge, this is the first published case report of migratory arthralgia and concomitant liver injury attributed to bicalutamide.

This interpretive research analyses the discourse of nurses who migrated to Canada and experienced racism. They also experienced reprisals when they formally complained about racism in a context of denial of the problem of racism by colleagues and employers. The present work focuses on two issues arising from the data: the problem of how to make racism visible among those who have a vested interest in denying its existence and the emotional cool of those filing grievances or complaints in contrast with the hot reaction of those being challenged when racism is named. We introduce two theoretical perspectives to address these phenomena called democratic racism and cosmopolitan citizenship, respectively. The former, as defined by Henry et al. (The Colour of Democracy: Racism in Canadian Society. Harcourt Brace, Canada, Toronto, 1996), describes the coexistence of both democratic values and practices that discount people of colour advertently or inadvertently. We outline the notion of cosmopolitan citizenship that is argued by Turner (Politics of the Global City. Routledge, London, 2000) to be an orientation resulting from global microcosms in cities teeming with diversity. The characteristic orientations of cool and stewardship are useful for describing some of the discourse expressed by each participant in our study all of whom challenged racism practices, not on nationalistic grounds, but rather out of concern for universal human rights. Their characteristics qualify them for cosmopolitan citizenship under Turner's perspective. We suggest that anti-racist activists have been cosmopolitan citizens for decades and argue that while cosmopolitan citizenship may have taken root in neo-liberal movements, it appears to have tactical attributes in the struggle with democratic racism. In conclusion, we advocate for a cosmopolitan citizenship ethic to facilitate a rational move toward racial integration in the profession through the sharing of power and privilege. One goal in
Full Text Available The text is concerned with the ways in which the territories, in this case the different rural areas and localities, are integrated, linked or dissociated into processes and chains of production and economic of a global order. The connection between territories and economic chains occurs through flows of goods, inputs and capital, but also through migratory movements and diverse mobility practices. The process of social division of labor generates new logics of integration / disintegration of the regions in the socioeconomic process, and different mobility demands associated with these changes. The hypothesis that encloses this text is that places and territories will reach to insert in global chains if they develop capacities of adaptability to the productive conditions and especially they manage to reduce the territorial friction guaranteeing the migratory management and mobility of the labor force. With this point of view the socio-agricultural evolution of the rural areas in Spain is contemplated from the end of century XIX

Several hypotheses have been proposed to explain the evolution of protandrous migration, yet they have rarely been tested at the interspecific level. Here, we provide...... that the time-lag in spring passage between males and females of five Palearctic migratory songbird species is positively associated with levels of extrapair paternity available from the literature. This suggests that males arrive relatively more in advance of females in species with high sperm competition...

Migration is one of the most spectacular of animal behaviors and is prevalent across a broad array of taxa. In birds, we know much about the physiological basis of how birds migrate, but less about the relative contribution of genetic versus environmental factors in controlling migratory tendency. To evaluate the extent to which migratory decisions are genetically determined, we examined whether individual western burrowing owls (Athene cunicularia hypugaea) change their migratory tendency from one year to the next at two sites in southern Arizona. We also evaluated the heritability of migratory decisions by using logistic regression to examine the association between the migratory tendency of burrowing owl parents and their offspring. The probability of migrating decreased with age in both sexes and adult males were less migratory than females. Individual owls sometimes changed their migratory tendency from one year to the next, but changes were one-directional: adults that were residents during winter 2004-2005 remained residents the following winter, but 47% of adults that were migrants in winter 2004-2005 became residents the following winter. We found no evidence for an association between the migratory tendency of hatch-year owls and their male or female parents. Migratory tendency of hatch-year owls did not differ between years, study sites or sexes or vary by hatching date. Experimental provision of supplemental food did not affect these relationships. All of our results suggest that heritability of migratory tendency in burrowing owls is low, and that intraspecific variation in migratory tendency is likely due to: (1) environmental factors, or (2) a combination of environmental factors and non-additive genetic variation. The fact that an individual's migratory tendency can change across years implies that widespread anthropogenic changes (i.e., climate change or changes in land use) could potentially cause widespread changes in the migratory tendency of

Long-distance dispersal (LDD) promotes the colonization of isolated and remote habitats, and thus it has been proposed as a mechanism for explaining the distributions of many species. Birds are key LDD vectors for many sessile organisms such as plants, yet LDD beyond local and regional scales has never been directly observed nor quantified. By sampling birds caught while in migratory flight by GPS-tracked wild falcons, we show that migratory birds transport seeds over hundreds of kilometres and mediate dispersal from mainland to oceanic islands. Up to 1.2% of birds that reached a small island of the Canary Archipelago (Alegranza) during their migration from Europe to Sub-Saharan Africa carried seeds in their guts. The billions of birds making seasonal migrations each year may then transport millions of seeds. None of the plant species transported by the birds occurs in Alegranza and most do not occur on nearby Canary Islands, providing a direct example of the importance of environmental filters in hampering successful colonization by immigrant species. The constant propagule pressure generated by these LDD events might, nevertheless, explain the colonization of some islands. Hence, migratory birds can mediate rapid range expansion or shifts of many plant taxa and determine their distribution. © 2016 The Author(s).

Birds are important hosts and dispersers of parasitic arthropods and vector-borne zoonotic pathogens. Particularly migratory species may carry these parasites over long distances in short time periods. Migratory hotspots present ideal conditions to get a snapshot of parasite and pathogen diversity of birds migrating between continents. The aim of this study was to investigate the presence and diversity of Rickettsia spp. in ticks collected from birds at a migratory hot-spot in the Danube Delta, Romania, eastern Europe. DNA was extracted from ticks that were collected from migratory birds in the Danube Delta during migratory seasons in 2011-2012. Two 360 bp fragments of the 16S ribosomal RNA gene and a 381 bp fragment Gene gltA were PCR amplified and analyzed by sequence analysis (performed at Macrogen Europe, Amsterdam, The Netherlands). Nucleotide sequences were compared to reference sequences available in the GenBank database, using Basic Local Alignment Search Tool. Four hundred ticks of four different species were found on 11 bird species. The prevalence of Rickettsia spp. infection was 14 % (56/400, CI: 11.7-29.1), with significantly more nymphs hosting rickettsial infection compared to larvae (48 vs 7; P birds migrating through eastern Europe may carry ticks infected with a high diversity of rickettsial pathogens, with four Rickettsia spp. recorded. Migratory direction was important for pathogen burden, with seasonal differences in the occurrence of individual Rickettsia species. Here we report the first individual records of different Rickettsia spp. in H. concinna (R. monacensis), I. arboricola (R. helvetica, R. massiliae) and I. redikorzevi (R. helvetica) and also the first geographical record of occurrence of R. massiliae in Romania, representing the easternmost observation on the continent.

One of the widely accepted consequences of globalization is the development of individual outlooks, behaviours and feelings that transcend local and national boundaries. This has encouraged a re-assessment of important assumptions about the nature of community, personal attachment and belonging in the face of unprecedented opportunities for culture, identities and politics to shape, and be shaped by, global events and processes. Recently, the upsurge of interest in the concept of cosmopolitanism has provided a promising new framework for understanding the nexus between cosmopolitan dispositions and global interconnectedness across cultural, political and economic realms. Using data from a representative social survey of Australians this paper investigates the negotiation of belonging under the conditions of globalization. The data tap into attitudes and behaviours associated with a broad gamut of cosmopolitan traits in the domains of culture, consumption, human rights, citizenship, and international governance. They show how cosmopolitan outlooks are shaped by social structural factors, and how forms of identification with humanity and the globe are fractured by boundaries of self and others, threats and opportunities, and the value of things global and local.
The paper considers Martha Nussbaum's motivation for departing from her earlier cosmopolitan position in favour of now promoting a globally sensitive patriotism.

Full Text Available We use the works of Diogenes and Zeno to argue that the cosmopolitan world view remains torn between negation and conformation; between anti-conventional resistance against and super-conventional organization of power. In their separate codes and relations to convention, Diogenes and Zeno expose complementary and conflictual sides of cosmopolitanism: in Diogenes, a challenge to local regimes, and in Zeno a plan for overcoming them; but in Diogenes a political programme that cannot attain its own ends, and in Zeno a political solution that comes unmoored from its foundations. Today, the International Criminal Court combines the two elements of cosmopolitanism in its responses to international crimes. In short, the particular practices of international criminal law and its grand gestures are in tension, undermining the aspiration to a positive programme of justice. We illustrate the tension that results through a discussion of two of the artworks that form the topic of this special issue of the Utrecht Law Review. As a result, the enterprise of international criminal justice, like the cosmopolitan programme that we trace back to Diogenes and Zeno, appears to become self-defeating.
How relevant are figures from the classical sociological canon for present day efforts to found cosmopolitan forms of sociological thought? According to the critique of Ulrich Beck, the classical sociologists remain far too wedded to nation-state-centred ways of thinking to play an important role in the development of cosmopolitan sociology. This paper argues that such a critique fails to account for the ways in which certain classical sociologists were attuned to the emerging cosmopolitical conditions of their own time, were not wholly wedded to nation-state-based conceptualizations, and thus can function as both groundings of, and inspirations for, cosmopolitan sociological endeavours. The apparently unpromising case of Tönnies is focused on, the paper showing how he outlined an account of how and why a planet-spanning condition of Gesellschaft developed a position which diverges from and counterpoints Marx's analysis of similar phenomena in important ways. The stereotype of Tönnies as an arch-conservative is also dissolved, allowing him to be considered as one of the most important antecedents of contemporary cosmopolitan sociological practice and a canonical figure still relevant for present-day purposes.

Full Text Available Phragmites australis is a cosmopolitan grass and often the dominant species in the ecosystems it inhabits. Due to high intraspecific diversity and phenotypic plasticity, P. australis has an extensive ecological amplitude and a great capacity to acclimate to adverse environmental conditions; it can therefore offer valuable insights into plant responses to global change. Here we review the ecology and ecophysiology of prominent P. australis lineages and their responses to multiple forms of global change. Key findings of our review are that: (1 P. australis lineages are well-adapted to regions of their phylogeographic origin and therefore respond differently to changes in climatic conditions such as temperature or atmospheric CO2; (2 each lineage consists of populations that may occur in geographically different habitats and contain multiple genotypes; (3 the phenotypic plasticity of functional and fitness-related traits of a genotype determine the responses to global change factors; (4 genotypes with high plasticity to environmental drivers may acclimate or even vastly expand their ranges, genotypes of medium plasticity must acclimate or experience range-shifts, and those with low plasticity may face local extinction; (5 responses to ancillary types of global change, like shifting levels of soil salinity, flooding, and drought, are not consistent within lineages and depend on adaptation of individual genotypes. These patterns suggest that the diverse lineages of P. australis will undergo intense selective pressure in the face of global change such that the distributions and interactions of co-occurring lineages, as well as those of genotypes within-lineages, are very likely to be altered. We propose that the strong latitudinal clines within and between P. australis lineages can be a useful tool for predicting plant responses to climate change in general and present a conceptual framework for using P. australis lineages to predict plant responses

Recent increases in human disturbance pose significant threats to migratory species using collective movement strategies. Key threats to migrants may differ depending on behavioural traits (e.g. collective navigation), taxonomy and the environmental system (i.e. freshwater, marine or terrestrial) associated with migration. We quantitatively assess how collective navigation, taxonomic membership and environmental system impact species' vulnerability by (i) evaluating population change in migratory and non-migratory bird, mammal and fish species using the Living Planet Database (LPD), (ii) analysing the role of collective navigation and environmental system on migrant extinction risk using International Union for Conservation of Nature (IUCN) classifications and (iii) compiling literature on geographical range change of migratory species. Likelihood of population decrease differed by taxonomic group: migratory birds were more likely to experience annual declines than non-migrants, while mammals displayed the opposite pattern. Within migratory species in IUCN, we observed that collective navigation and environmental system were important predictors of extinction risk for fishes and birds, but not for mammals, which had overall higher extinction risk than other taxa. We found high phylogenetic relatedness among collectively navigating species, which could have obscured its importance in determining extinction risk. Overall, outputs from these analyses can help guide strategic interventions to conserve the most vulnerable migrations.This article is part of the theme issue 'Collective movement ecology'. © 2018 The Author(s).

Global warming is impacting biodiversity by altering the distribution, abundance, and phenology of a wide range of animal and plant species. One of the best documented responses to recent climate change is alterations in the migratory behavior of birds, but the mechanisms underlying these phenotypic adjustments are largely unknown. This knowledge is still crucial to predict whether populations of migratory birds will adapt to a rapid increase in temperature. We monitored migratory behavior in...

Anillini are a tribe of minute, euedaphic ground beetles (Carabidae) characterized by the loss of eyes, loss of wings and high levels of local endemism. Despite their presumed low dispersal, they have a nearly cosmopolitan distribution, including isolated islands such as New Zealand and New Caledonia. We used a time calibrated molecular phylogeny to test, first, if the tribe as currently understood is monophyletic and, second, whether the time of divergence is compatible with an early vicariant diversification after the breakup of Gondwana. We sequenced portions of 6 mitochondrial and 3 nuclear genes for 66 specimens in 17 genera of Anillini plus 39 outgroups. The resulting phylogenetic tree was used to estimate the time of diversification using two independent calibration schemes, by applying molecular rates for the related genus Carabus or by dating the tree with fossil and geological information. Rates of molecular evolution and lineage ages were mostly concordant between both calibration schemes. The monophyly of Anillini was well-supported, and its age was consistent with a Gondwanian origin of the main lineages and an initial diversification at ca. 100Ma representing the split between the eyed Nesamblyops (New Zealand) and the remaining Anillini. The subsequent diversification, including the split of the Nearctic Anillinus and the subsequent splits of Palaearctic lineages, was dated to between 80 and 100Ma and thus was also compatible with a tectonic vicariant origin. On the contrary, the estimated age of the New Caledonian blind Orthotyphlus at ca. 30±20Ma was incompatible with a vicariant origin, suggesting the possibility of trans-oceanic dispersal in these endogean beetles.

Full Text Available At the end of World War 2, there were high hopes across the Indian Ocean for a new world in which the relationships between working people would mean more than the borders which separated them. This paper will explore the fate of the hopes for new worlds, in the decades after 1945, by following the uneven relationships among working class Australians, Indonesians and Indians in the aftermath of an intense political struggle in Australia from 1945 to 1949 in support of Indonesian independence. They had been brought together by intersections between the networks established through colonialism, like trade unions, communism and feminism, with those having much longer histories, like Islam. The men and women in this Australian setting expressed their vision in 1945 for a future of universal and transnational networks across the Indian Ocean which would continue the alliances they had found so fruitful. Today their experiences as well as their hopes might be called cosmopolitanism – they expected that the person-to-person friendships they were forming could be sustained and be able to negotiate the differences between them to achieve common aims. Although these hopes for new futures of universal alliances and collaborations were held passionately in the 1940s, all seem to have died by 1970, diverted by newly independent national trajectories and defeated by the Cold War. Yet many of the relationships persisted far longer than might be expected and their unravelling was not inevitable. This paper will trace the course of a few of the relationships which began in the heat of the campaigns in Australia, 1943 to 1945, in order to identify the continuing common ground as well as the rising tensions which challenged them.

Legal removal of migratory birds from the wild occurs for several reasons, including subsistence, sport harvest, damage control, and the pet trade. We argue that harvest theory provides the basis for assessing the impact of authorized take, advance a simplified rendering of harvest theory known as potential biological removal as a useful starting point for assessing take, and demonstrate this approach with a case study of depredation control of black vultures (Coragyps atratus) in Virginia, USA. Based on data from the North American Breeding Bird Survey and other sources, we estimated that the black vulture population in Virginia was 91,190 (95% credible interval = 44,520?212,100) in 2006. Using a simple population model and available estimates of life-history parameters, we estimated the intrinsic rate of growth (rmax) to be in the range 7?14%, with 10.6% a plausible point estimate. For a take program to seek an equilibrium population size on the conservative side of the yield curve, the rate of take needs to be less than that which achieves a maximum sustained yield (0.5 x rmax). Based on the point estimate for rmax and using the lower 60% credible interval for population size to account for uncertainty, these conditions would be met if the take of black vultures in Virginia in 2006 was < 3,533 birds. Based on regular monitoring data, allowable harvest should be adjusted annually to reflect changes in population size. To initiate discussion about how this assessment framework could be related to the laws and regulations that govern authorization of such take, we suggest that the Migratory Bird Treaty Act requires only that take of native migratory birds be sustainable in the long-term, that is, sustained harvest rate should be < rmax. Further, the ratio of desired harvest rate to 0.5 x rmax may be a useful metric for ascertaining the applicability of specific requirements of the National Environmental Protection Act.

The challenge for migratory bird conservation is habitat preservation that sustains breeding, migration, and non-breeding biological processes. In choosing an appropriately scaled conservation arena for habitat preservation, a conservative and thorough examination of stopover habitat use patterns by migrants works back from the larger scales at which such relationships may occur. Because the use of stopover habitats by migrating birds occurs at spatial scales larger than traditional field techniques can easily accommodate, I quantify these relationship using the United States system of weather surveillance radars (popularly known as NEXRAD). To provide perspective on use of this system for biologists, I first describe the technical challenges as well as some of the biological potential of these radars for ornithological research. Using data from these radars, I then examined the influence of Lake Michigan and the distribution of woodland habitat on migrant concentrations in northeastern Illinois habitats during stopover. Lake Michigan exerted less influence on migrant abundance and density than the distribution and availability of habitat for stopover. There was evidence of post-migratory movement resulting in habitats within suburban landscapes experiencing higher migrant abundance but lower migrant density than habitats within nearby urban and agricultural landscapes. Finally, in the context of hierarchy theory, I examined the influence of landscape ecological and behavioral processes on bird density during migratory stopover. Migrant abundance did not vary across landscapes that differed considerably in the amount of habitat available for stopover. As a result, smaller, more isolated patches held higher densities of birds. Spatial models of migrant habitat selection based on migrant proximity to a patch explained nearly as much variance in the number of migrants occupying patches (R2 = 0.88) as selection models based on migrant interception of patches during

The intra- and inter-season complexity of bird migration has received limited attention in climatic change research. Our phenological analysis of 22 species collected in Chicago, USA, (1979 2002) evaluates the relationship between multi-scalar climate variables and differences (1) in arrival timing between sexes, (2) in arrival distributions among species, and (3) between spring and fall migration. The early migratory period for earliest arriving species (i.e., short-distance migrants) and earliest arriving individuals of a species (i.e., males) most frequently correlate with climate variables. Compared to long-distance migrant species, four times as many short-distance migrants correlate with spring temperature, while 8 of 11 (73%) of long-distance migrant species’ arrival is correlated with the North Atlantic Oscillation (NAO). While migratory phenology has been correlated with NAO in Europe, we believe that this is the first documentation of a significant association in North America. Geographically proximate conditions apparently influence migratory timing for short-distance migrants while continental-scale climate (e.g., NAO) seemingly influences the phenology of Neotropical migrants. The preponderance of climate correlations is with the early migratory period, not the median of arrival, suggesting that early spring conditions constrain the onset or rate of migration for some species. The seasonal arrival distribution provides considerable information about migratory passage beyond what is apparent from statistical analyses of phenology. A relationship between climate and fall phenology is not detected at this location. Analysis of the within-season complexity of migration, including multiple metrics of arrival, is essential to detect species’ responses to changing climate as well as evaluate the underlying biological mechanisms.

The distinction between native and introduced biotas presents unique challenges that culminate in organisms with high long-distance dispersal capacities in a rapidly changing world. Bryophytes, in particular, exhibit large distribution ranges, and some species can truly be qualified as cosmopolitan. Cosmopolitan species, however, typically occur in disturbed environments, raising the question of their nativeness throughout their range. Here, we employ genetic data to address the question of the origin of the cosmopolitan, weedy moss Bryum argenteum on the island of Tenerife. The genetic diversity of B. argenteum on Tenerife was comparable to that found in continental areas due to recurrent colonisation events, erasing any signature of a bottleneck that would be expected in the case of a recent colonisation event. The molecular dating analyses indicated that the first colonisation of the island took place more than 100,000 years ago, i.e. well before the first human settlements. Furthermore, the significant signal for isolation-by-distance found in B. argenteum within Tenerife points to the substantial role of genetic drift in establishing the observed patterns of genetic variation. Together, the results support the hypothesis that B. argenteum is native on Tenerife; although the existence of haplotypes shared between Tenerife and continental areas suggests that more recent, potentially man-mediated introduction also took place. While defining nativeness in organisms that are not deliberately introduced, and wherein the fossil record is extremely scarce, is an exceedingly challenging task, our results suggest that population genetic analyses can represent a useful tool to help distinguish native from alien populations. © 2015 German Botanical Society and The Royal Botanical Society of the Netherlands.

Full Text Available BACKGROUND: The adaptive transition between behavioral strategies, such as the shift from migratoriness to sedentariness, remains an outstanding question in evolutionary ecology. Density-dependent variation in the age of first breeding has been proposed as a feasible mechanism through which long-lived migratory birds with deferred sexual maturity should become sedentary to persist on islands. Although this pattern seems to hold for most raptors and herons, a few exceptions have been identified. One of these exceptions is the Eleonora's falcon, a long-distance migratory bird, which shows one of the most peculiar adaptations in the timing of reproduction and food requirements among raptors. METHODOLOGY/PRINCIPAL FINDINGS: Here, we compiled data concerning demography, banding recoveries and satellite tracking of Eleonora's falcons to discuss likely explanations for the exceptional behavior of this insular long-distance migratory species. CONCLUSIONS/SIGNIFICANCE: New data reveal that Eleonora's falcons do return to the natal colonies in their first year and young birds are able to breed. However, in contrast to previous hypothesis, the highly specialized strategy of this and other ecologically similar species, as well as the virtual lack of food during winter at breeding areas prevent them from becoming sedentary on islands. Although the ultimate mechanisms underlying the process of sedentarization remain poorly understood, the evidence provided reveal the existence of important trade-offs associated with ecological specialization that may become particularly relevant in the present context of global change.

The most appropriate way of theorizing cultural diversity is to situate it in the context of a broader relational theory of culture in which the key dynamic is cultural encounters. The relational conception of culture places the emphasis on the relations between social actors and the processes by which some of these relations generate enduring cultural regularities and forms. This has important implications for political community and in particular for cosmopolitanism. It is in relationships that cultural phenomena are generated and become the basis of different kinds of political community. The paper outlines a typology of six kinds of cultural encounters and discusses four major cultural trends that variously emerge from these encounters. This approach with its emphasis on cultural encounters is the broad sociological context in which questions about cultural change and the prospects of cosmopolitanism should be discussed. © London School of Economics and Political Science 2011.
Full Text Available The novels of Caryl Phillips have most commonly been approached from post-colonial theoretical perspectives, a trend which appears entirely appropriate given their recurrent themes of immigration, ethnic discrimination and the legacy of the trans-Atlantic slave trade. However, the analysis below contends that the publication of A Distant Shore marked a change of direction in Phillips's oeuvre towards a less formally experimental but thematically more cosmopolitan form of writing that conspicuously sets out to subvert and redefine the idea of 'home'. Using the critical frameworks of Avtar Brah, Paul Gilroy and Jacques Derrida, the discussion will illustrate how Phillips critically re-imagines the notion 'home' in order to signify an inclusive space of cosmopolitan conviviality and openness.

Full Text Available In this article, we present a case study analysis of data gathered on the practice of the art of Taijiquan (Tai Chi Chuan in one UK context. Our interest in looking at this physical culture was in exploring if/how physical cultures of shared embodied experience and practice may help “sow the seeds of environmental awareness”. In so doing, we illustrate certain affinities between this interpretation of the art and Beck’s idea of a “cosmopolitan vision of ecology”. We present an analysis of documentary and interview data of one English Taijiquan organisation and how it currently promotes the idea of interconnectedness, wellbeing and an alternative meta-narrative for living through the practice of Taijiquan. We conclude that, while further research is needed, there is evidence that a cosmopolitan vision for ecology is emerging in physical cultures such as Taijiquan.

Dubai-one of the seven United Arab Emirates and the Middle East's only "global city"-is gaining a reputation as a transnational medical tourism hub. Characterized by its "medical cosmopolitanism," Dubai is now attracting medical travelers from around the world, some of whom are seeking assisted conception. Dubai is fast becoming known as a new transnational "reprohub" for intracytoplasmic sperm injection (ICSI), the variant of in vitro fertilization designed to overcome male infertility. Based on ethnographic research conducted in one of the country's most cosmopolitan clinics, this article explores the ICSI treatment quests of infertile men coming to Dubai from scores of other nations. The case of an infertile British-Moroccan man is highlighted to demonstrate why ICSI is a particularly compelling "masculine hope technology" for infertile Muslim men. Thus, Muslim men who face barriers to ICSI access in their home countries may become "reprotravelers" to Dubai, an emergent ICSI depot. © 2016 by the American Anthropological Association.
Against Beck's claims that conventional sociological concepts and categories are zombie categories, this paper argues that Durkheim's theoretical framework in which suicide is a symptom of an anomic state of society can help us understand the diversity of trajectories that transnational migrants follow and that shape their suicide rates within a cosmopolitan society. Drawing on ethnographic data collected on eight suicides and three attempted suicide cases of second-generation male Alevi Kurdish migrants living in London, this article explains the impact of segmented assimilation/adaptation trajectories on the incidence of suicide and how their membership of a 'new rainbow underclass', as a manifestation of cosmopolitan society, is itself an anomic social position with a lack of integration and regulation. © London School of Economics and Political Science 2016.

Global warming is impacting biodiversity by altering the distribution, abundance, and phenology of a wide range of animal and plant species. One of the best documented responses to recent climate change is alterations in the migratory behavior of birds, but the mechanisms underlying these phenotypic adjustments are largely unknown. This knowledge is still crucial to predict whether populations of migratory birds will adapt to a rapid increase in temperature. We monitored migratory behavior in a population of blackcaps (Sylvia atricapilla) to test for evolutionary responses to recent climate change. Using a common garden experiment in time and captive breeding we demonstrated a genetic reduction in migratory activity and evolutionary change in phenotypic plasticity of migration onset. An artificial selection experiment further revealed that residency will rapidly evolve in completely migratory bird populations if selection for shorter migration distance persists. Our findings suggest that current alterations of the environment are favoring birds wintering closer to the breeding grounds and that populations of migratory birds have strongly responded to these changes in selection. The reduction of migratory activity is probably an important evolutionary process in the adaptation of migratory birds to climate change, because it reduces migration costs and facilitates the rapid adjustment to the shifts in the timing of food availability during reproduction.
Izmir is a somewhat privileged case, among the “cosmopolitan” port cities of the Ottoman Eastern Mediterranean, in terms of the number of studies devoted to it. However, although scholars dealing with Izmir’s history almost unanimously cite its cosmopolitan character, most of them examine the city from the perspective of individual ethnic and religious minorities. An obvious disadvantage of such an approach is that it ignores the relational dimension of group formation: minority communities c...

Full Text Available In the aftermath of the last financial crisis a strong message prevails that ‘something’ has to be changed in the manner global finance is governed. What exactly this ‘something’ entails and what could constitute the ‘common ground’ of anticipated change is more difficult to determine. Many envisage future improvements of global financial governance by evoking deliberative democracy, political equality and cosmopolitanism. As financial regulation is the main instrument through which global finance is shaped and governed nowadays, these principles should then be transmitted to regulatory arrangements. This paper focuses on a new conceptual approach to regulatory and governance issues in global finance, by employing the philosophical idea of cosmopolitanism. It argues that although as a concept, cosmopolitanism cannot mitigate all the flaws attributed to contemporary finance, its development and extension to international financial regulation that is promulgated by institutions of the global financial system, would represent a worthwhile endeavour in making global finance more accountable and just in the eyes of many.
Full Text Available Migrants originating from Singkawang, West Kalimantan, Indonesia, experience limitations in their ability to engage in host societies overseas despite their hopes and fantasies of becoming cosmopolitan transnational citizens. Marginality, stemming from the lower status associated with being a migrant, as well as forms of parochialism which hinder the ability to adopt a flexible attitude to cultural difference combine and lead to a significant reimagining of those original cosmopolitan fantasies. Essentializing characterizations of “us” versus “them” reveal some of the difficulties of being received in other societies and come to constitute a recuperative discourse in which migrants can preserve a sense of self –as Hakka Chinese Indonesians –when the value of that identity is called into question. In this context, migrants experience practical limitations in translating cosmopolitan fantasies into lived realities. As a response, a romantic nostalgia for the home is constructed, which in turn provides the imaginative resources used for planning a return to the kampung halaman (Indonesian: home/home town.
Full Text Available In the past ten years, groups of local artists, architects, writers and activists have become concerned not only with the changing material conditions of Casablanca, but also with the city’s memory. This essay is concerned with two projects that reveal how nostalgic modes of recollection expose and limit geographies of cosmopolitan identity in the city. The first project, a collection of twelve booklets written by prominent novelists and poets with well-known photographers, is entitled Casablanca, fragments d’imaginaire . This collection argues that nostalgia and phantasm are key organizing concepts through which the city should be recollected, claiming that these modes of representation produce multiple, plural and heterogeneous forms and imaginations that allow the “soul” of the city to emerge. The second project is a participatory urban archeology art project started by the art collective La Source du lion . The collective practices a non-nostalgic curation of memory that moves cosmopolitanism in the city beyond a historical category into a contemporary practice and ethos. Read comparatively, these projects shed light on two post-colonial generations of writers and artists, their claims to the colonial past, identity politics about cosmopolitanism in the present, and struggles over cultural capital for the future.
Full Text Available This article explores the problem of the public acceptability of political inaction as an extreme consequence of cosmopolitan utilitarianism. The case of political inaction as the utility-maximizing public policy option emerges more clearly in the globalized world, because of a misalignment between the electoral body and the persons that the government ought to consider while evaluating the consequences of a given policy. In this context, a situation can easily occur in which the only way to maximize utility in a global context is by renouncing action at the national or local level. However, the problem of inaction should not be interpreted simply as a by-product of globalization. Its origins can be traced to the basic structure of utilitarianism as a normative consequentialist theory. This drawback can even present itself at the local level in a less visible form. One example is that in which the performance of a supererogatory act in the exercise of public office leads to a reduction in overall utility. The aim of the article is to demonstrate that cosmopolitan utilitarianism can bind the decision maker to a series of inactions at the global and local levels that contradict his own mandate, generating a dangerous moral confusion in the implementation of public policies. This can seriously threaten the universal applicability of cosmopolitan utilitarianism as a normative political theory, especially in the age of globalization.
Full Text Available Correcting the Eyesight: Cosmopolitanism in Chinua Achebe’s Things Fall Apart Abstract The evolutionary process of separatist efforts such as colonialism, imperialism, globalization, neo-colonialism or any nationalism are outdated because global resources are becoming scarce every day, so such terms as human solidarity, Cosmopolitanism, and co-existence will have to endure in order to make use of the resources in the most optimum way. Mankind will have to understand that global sameness has to prevail despite long years of hostility, violence and bloodshed. In line with such an understanding, cosmopolitanism, as a term refers to world citizenship and 'a tolerance for things and people who are different’ and 'morality which is not rooted locally, but globally.’ Chinua Achebe tries to change the African images created by the writers depending on Eurocentric and Afrocentric perspectives. He handles the same periphery from an unusual viewpoint that is because he utilizes a different approach in representing Africa and composes counter discourses in response to colonial, imperial and racial discourses presented in colonial contexts.

Understanding the impacts of climate on migratory species is complicated by the fact that these species travel through several climates that may be changing in diverse ways throughout their complete migratory cycle. Most studies are not designed to tease out the direct and indirect effects of climate at various stages along the migration route. We assess the impacts of spring and summer climate conditions on breeding monarch butterflies, a species that completes its annual migration cycle over several generations. No single, broad-scale climate metric can explain summer breeding phenology or the substantial year-to-year fluctuations observed in population abundances. As such, we built a Poisson regression model to help explain annual arrival times and abundances in the Midwestern United States. We incorporated the climate conditions experienced both during a spring migration/breeding phase in Texas as well as during subsequent arrival and breeding during the main recruitment period in Ohio. Using data from a state-wide butterfly monitoring network in Ohio, our results suggest that climate acts in conflicting ways during the spring and summer seasons. High spring precipitation in Texas is associated with the largest annual population growth in Ohio and the earliest arrival to the summer breeding ground, as are intermediate spring temperatures in Texas. On the other hand, the timing of monarch arrivals to the summer breeding grounds is not affected by climate conditions within Ohio. Once in Ohio for summer breeding, precipitation has minimal impacts on overall abundances, whereas warmer summer temperatures are generally associated with the highest expected abundances, yet this effect is mitigated by the average seasonal temperature of each location in that the warmest sites receive no benefit of above average summer temperatures. Our results highlight the complex relationship between climate and performance for a migrating species and suggest that attempts to
In many European countries, foreigners constitute the majority of certain groups of prostitutes, e.g., approximately 90% of the window prostitutes in the red light district of Amsterdam are not native to the Netherlands. The same is true for prostitutes working in bars in Vienna. In cities where registered prostitution is legal, unregistered prostitutes, most of whom are foreigners, often outnumber the registered ones. Central European countries often receive "sex workers" from eastern Europe, e.g., from Bulgaria, the Czech Republic, Slovakia, Hungary, and Romania, whereas the majority of migratory prostitutes in Great Britain and continental western Europe come from Africa, the Caribbean, and South America. In northern Europe, women from Russia, the Czech Republic, Slovakia, Poland, and the Baltic states are prostituting themselves in increasing numbers. Scandinavia has so far been affected relatively less by this mobility. In Spain, France, and Italy, women from Arabic and subSaharan countries are common among prostitutes. Foreign prostitutes move into Turkey along two main routes: women from the Balkan countries come to the western part of the country, whereas those from the former Soviet Union cross the border from Georgia, where they usually operate at resorts along the eastern Black Sea coast. Prostitutes are also mobile within the former communist bloc. For instance, women from Russia prostitute themselves in Lithuania, the Czech Republic, Slovakia, and Hungary. the customers are locals, particularly those with "hard currency", such as businessmen and "sex tourists" from the West. Following the outbreak of civil war in the former Yugoslavia, women from that country are now more frequently seen among the population of migratory prostitutes in Europe.

Full Text Available Abstract Background Nematodes represent the most abundant benthic metazoa in one of the largest habitats on earth, the deep sea. Characterizing major patterns of biodiversity within this dominant group is a critical step towards understanding evolutionary patterns across this vast ecosystem. The present study has aimed to place deep-sea nematode species into a phylogenetic framework, investigate relationships between shallow water and deep-sea taxa, and elucidate phylogeographic patterns amongst the deep-sea fauna. Results Molecular data (18 S and 28 S rRNA confirms a high diversity amongst deep-sea Enoplids. There is no evidence for endemic deep-sea lineages in Maximum Likelihood or Bayesian phylogenies, and Enoplids do not cluster according to depth or geographic location. Tree topologies suggest frequent interchanges between deep-sea and shallow water habitats, as well as a mixture of early radiations and more recently derived lineages amongst deep-sea taxa. This study also provides convincing evidence of cosmopolitan marine species, recovering a subset of Oncholaimid nematodes with identical gene sequences (18 S, 28 S and cox1 at trans-Atlantic sample sites. Conclusions The complex clade structures recovered within the Enoplida support a high global species richness for marine nematodes, with phylogeographic patterns suggesting the existence of closely related, globally distributed species complexes in the deep sea. True cosmopolitan species may additionally exist within this group, potentially driven by specific life history traits of Enoplids. Although this investigation aimed to intensively sample nematodes from the order Enoplida, specimens were only identified down to genus (at best and our sampling regime focused on an infinitesimal small fraction of the deep-sea floor. Future nematode studies should incorporate an extended sample set covering a wide depth range (shelf, bathyal, and abyssal sites, utilize additional genetic loci (e

Migratory birds face many changes to the landscapes they traverse and the habitats they use. Wind turbines and communications towers, which pose hazards to birds and bats in flight, are being erected across the United States and offshore. Human activities can also destroy or threaten habitats critical to birds during migratory passage, and climate change appears to be altering migratory patterns. The U.S. Fish and Wildlife Service (USFWS) and other agencies are under increasing pressure to identify and evaluate movement patterns and habitats used during migration and other times.

Full Text Available The works of Henry James with their attention to cosmopolitanism in the late nineteenth and early twentieth centuries provide valuable insight into contemporary expectations of cultural hybridity and globalism. This paper assesses the ways students studying English as a foreign language in Taiwan read the cultural exchanges between Americans and Europeans in James’s "The American" (1877 and "The Portrait of a Lady" (1881. It places the main attention upon how students evaluate James’s characters based upon their own attitudes toward cosmopolitanism, work and leisure, and women’s independence. Informed by the travel theory of Mary Louise Pratt (2008 and Homi Bhabha’s (1994 concept of the third space, it studies the negotiation and subversion of meaning in postcolonial and reverse-colonial contexts. The analysis of student responses reveals that in this culturally hybrid reading site, the limited consciousness technique of James generates judgments of characters’ potentialities based upon the students’ own values. Reconciling the cultural oppositions in the self to become a citizen of the world remains an ideal they do not see fully realized in James’s highly conflicted characters, and, as their own partial views attest, not realizable in their own lives.

The amazing accuracy of migratory orientation performance across the animal kingdom is facilitated by the use of magnetic and celestial compass systems that provide individuals with both directional and positional information. Quantitative genetics analyses in several animal systems suggests that migratory orientation has a strong genetic component. Nevertheless, the exact identity of genes controlling orientation remains largely unknown, making it difficult to obtain an accurate understanding of this fascinating behavior on the molecular level. Here, we provide an overview of molecular genetic techniques employed thus far, highlight the pros and cons of various approaches, generalize results from species-specific studies whenever possible, and evaluate how far the field has come since early quantitative genetics studies. We emphasize the importance of examining different levels of molecular control, and outline how future studies can take advantage of high-resolution tracking and sequencing techniques to characterize the genomic architecture of migratory orientation.

Migratory waterfowl, especially ducks, are considered the main hosts of low pathogenic avian influenza virus, but the role of geese in dispersing the virus over long-distances is still unclear. We collected throat and cloaca samples from three goose species, Bean goose (Anser fabalis), Barnacle goose (Branta leucopsis) and Greater white-fronted goose...

Full Text Available The origin of recent parallel outbreaks of the high pathogenicity H5N8 avian flu virus in Europe and in Japan can be traced to a single source population, which has most likely been spread by migratory birds. By using Bayesian coalescent methods to analyze the DNA sequences of the virus to find the times for divergence and combining this sequence data with bird migration data we can show the most likely locations and migratory pathways involved in the origin of the current outbreak. This population was most likely located in the Siberian summer breeding grounds of long-range migratory birds. These breeding grounds provide a connection between different migratory flyways and explain the current outbreaks in remote locations. By combining genetic methods and epidemiological data we can rapidly identify the sources and the dispersion pathways for novel avian influenza outbreaks.

Full Text Available Brain structure and function are tightly correlated across all animals. While these relations are ultimately manifestations of differently wired neurons, many changes in neural circuit architecture lead to larger-scale alterations visible already at the level of brain regions. Locating such differences has served as a beacon for identifying brain areas that are strongly associated with the ecological needs of a species—thus guiding the way towards more detailed investigations of how brains underlie species-specific behaviors. Particularly in relation to sensory requirements, volume-differences in neural tissue between closely related species reflect evolutionary investments that correspond to sensory abilities. Likewise, memory-demands imposed by lifestyle have revealed similar adaptations in regions associated with learning. Whether this is also the case for species that differ in their navigational strategy is currently unknown. While the brain regions associated with navigational control in insects have been identified (central complex (CX, lateral complex (LX and anterior optic tubercles (AOTU, it remains unknown in what way evolutionary investments have been made to accommodate particularly demanding navigational strategies. We have thus generated average-shape atlases of navigation-related brain regions of a migratory and a non-migratory noctuid moth and used volumetric analysis to identify differences. We further compared the results to identical data from Monarch butterflies. Whereas we found differences in the size of the nodular unit of the AOTU, the LX and the protocerebral bridge (PB between the two moths, these did not unambiguously reflect migratory behavior across all three species. We conclude that navigational strategy, at least in the case of long-distance migration in lepidopteran insects, is not easily deductible from overall neuropil anatomy. This suggests that the adaptations needed to ensure successful migratory behavior
Foreign policy holds great potential to improve the health of a global citizenship. Our contemporary political order is, in part, characterized by sovereign states acting either in opposition or cooperation with other sovereign states. This order is also characterized by transnational efforts to address transnational issues such as those featured so prominently in the area of global health, such as the spread of infectious disease, health worker migration and the movement of health-harming products. These two features of the current order understandably create tension for truly global initiatives. National security has become the dominant ethical frame underlying the health-based foreign policy of many states, despite the transnational nature of many contemporary health challenges. This ethical approach engages global health as a means to achieving national security objectives. Implicit in this ethical frame is the version of humanity that dichotomizes between "us" and "them". What has been left out of this discourse, for the most part, is the role that foreign policy can play in extending the responsibility of states to protect and promote health of the other, for the sake of the other. The principal purpose of this paper is to review arguments for a cosmopolitan ethics of health-based foreign policy. I will argue that health-based foreign policy that is motivated by security interests is lacking both morally and practically to further global health goals. In other words, a cosmopolitan ethic is not only intrinsically superior as a moral ideal, but also has potential to contribute to utilitarian ends. This paper draws on the cosmopolitanism literature to build robust support for foreign policies that contribute to sustainable systems of global health governance.
Many migratory birds accumulate large amounts of lipids as the prime energy source for their long-distance flights. This fat accumulation is mostly under endogenous control, reflecting genetically programmed temporal shifts of the body mass set point. It is accompanied by an increase in daily food intake and food utilisation efficiency and by a seasonal shift in food selection. In particular, seasonal frugivory appears to play a key role in many migrants. Fruits have a high content of fatty acids indispensable for building up the specific depot lipids. In addition, plant secondary compounds seem to play some kind of supportive role, but the mechanisms are not yet known. The effect of being fat on the metabolic situation in migrant birds appears to be similar to the metabolic syndrome in obese humans. The fat migratory bird provides a model through which to study nutritional factors as well as the biochemical and endocrine regulation of food intake, body mass and obesity.
Full Text Available An ethnographic examination of the day-to-day networking sociality of financial elites in Malaysia, Singapore, and Hong Kong shows that, in line with ethnographic studies of core country elites, the subjectivities inculcated among hedge fund managers show racial and class cleavages, but in fund managers’ work, bridging capital structures takes primacy, while bridging structures of privilege remains unacknowledged and thus provides an advantage to those who display conspicuously cosmopolitan consumption and networking sociality. Simultaneously, fund managers’ pervasive ascription of objectivity to a perspective associated with white masculinity creates a structural disadvantage for women, racialized others, and those lacking training or networking capacity in core countries.

Full Text Available The world is not just connected; it is hyper-connected. The global flow of ideas, technology, and people are at unmatched levels in history. More classrooms are becoming cosmopolitan centers composed of students with multicultural backgrounds. However, United States public education in this hyper-connected world puts emphasis on standardization and accountability. By doing so, schools driven by federal initiatives fail in helping students to become worldly citizens. Students and teachers are derived of room for creativity or new multicultural possibilities. Hence, this paper intends to develop a theoretical framework for curriculum in the hyper-connected world, aptly named “hyper-curriculum.”
This essay argues that the writer E. B. White, best known for his literary essays and children’s books, also had a significant but neglected career as a political writer. It considers his writings, during and just after World War II, on the subject of world government, and argues that he made the case for world federation by way of a novel model of cosmopolitanism that results from love of place and country rather than from dispensing with them. It considers the reception of his 1946 book The...
Full Text Available This article seeks to demonstrate that Zadie Smith’s fourth novel, 'NW' (2012, deviates away from celebratory multiculturalism in Britain, interrogating the struggle between critical cosmopolitanism and melancholia in a twenty-first century urban environment. It will be argued that Smith’s limited geographical focus (on an area in which she was born and continues to reside intimates that the social constructs of the family and local community are more conducive to developing cosmopolitan empathy and meaningful relations. Through an analysis of the ethical values of hospitality and openness, it will be suggested that 'NW' reflects a rise in transnational relations and the construction of a cultural model of cosmopolitan communication haunted by national identity and the difficulties of negotiating cultural diversity. The article will then conclude by examining how 'NW' exposes the racial inequalities and socio-economic disparities continuing to reside at the heart of British urban life.

Full Text Available Assigning ecological roles to bacterial taxa remains imperative to understanding how microbial communities will respond to changing environmental conditions. Here we analyze the genus Curtobacterium as it was found to be the most abundant taxon in a leaf litter community in southern California. Traditional characterization of this taxon predominantly associates it as the causal pathogen in the agricultural crops of dry beans. Therefore, we seek to conduct a broad investigation into this genus to ask whether its high abundance in our soil system is in accordance with its role as a plant pathogen or if alternative ecological roles are needed. By collating >24,000 16S rRNA sequences with 120 genomes across the Microbacteriaceae family, we show that Curtobacterium has a global distribution with a predominant presence in soil ecosystems globally. Moreover, this genus harbors a high diversity of genomic potential for the degradation of carbohydrates, specifically with regards to structural polysaccharides. We conclude that Curtobacterium may be responsible for the degradation of organic matter within litter communities.

Recent evidence suggests that population declines in many Neotropical-wintering migratory landbird species are caused by habitat loss and degradation on their wintering grounds. Such habitat loss and degradation can lower overwintering survival rates and cause surviving birds to leave their wintering grounds in poor physical condition, leading to high mortality during...

The role of geographic isolation in marine microbial speciation is hotly debated because of the high dispersal potential and large population sizes of planktonic microorganisms and the apparent lack of strong dispersal barriers in the open sea. Here, we show that gene flow between distant populations of the globally distributed, bloom-forming diatom species Pseudo-nitzschia pungens (clade I) is limited and follows a strong isolation by distance pattern. Furthermore, phylogenetic analysis implies that under appropriate geographic and environmental circumstances, like the pronounced climatic changes in the Pleistocene, population structuring may lead to speciation and hence may play an important role in diversification of marine planktonic microorganisms. A better understanding of the factors that control population structuring is thus essential to reveal the role of allopatric speciation in marine microorganisms.

Full Text Available This work addresses a critical analysis of the nature of cosmopolitan order encouraged by the World Tourism Organization. Given the growth of tourism activity and the challenges that it poses, this specialized agency of the United Nations has formally promoted equitable, responsible and sustainable development of tourism. However, the criticism of the principles from which the organization shapes tourism has put the focus on the objectives pursued. The conversion of these principles, included in the Global Code of Ethics for Tourism, adopted in 1999, into an international convention, approved in September 2017, presents a new scene that this work outlines from the cosmopolitanism perspective.
Full Text Available Migratory species are an important component of biodiversity and provide essential ecosystem services for humans, but many are threatened and endangered. Numerous studies have been conducted on the biology of migratory species, and there is an increased recognition of the major role of human dimensions in conserving migratory species. However, there is a lack of systematic integration of socioeconomic and environmental factors. Because human activities affect migratory species in multiple places, integrating socioeconomic and environmental factors across space is essential, but challenging. The holistic framework of telecoupling (socioeconomic and environmental interactions over distances has the potential to help meet this challenge because it enables researchers to integrate human and natural interactions across multiple distant places. The use of the telecoupling framework may also lead to new conservation strategies and actions. To demonstrate its potential, we apply the framework to Kirtland’s warblers ('Setophaga kirtlandii' , a conservation-reliant migratory songbird. Results show accomplishments from long-term research and recovery efforts on the warbler in the context of the telecoupling framework. The results also show 24 research gaps even though the species has been relatively well-studied compared to many other species. An important gap is a lack of systematic studies on feedbacks among breeding, wintering, and stopover sites, as well as other “spillover” systems that may affect and be affected by migration (e.g., via tourism, land use, or climate change. The framework integrated scattered information and provided useful insights about new research topics and flow-centered management approaches that encapsulate the full annual cycle of migration. We also illustrate the similarities and differences between Kirtland’s warblers and several other migratory species, indicating the applicability of the telecoupling framework to

The migration of animals across long distances and between multiple habitats presents a major challenge for conservation. For the migratory Mexican free-tailed bat (Tadarida brasiliensis mexicana), these challenges include identifying and protecting migratory routes and critical roosts in two countries, the United States and Mexico. Knowledge and conservation of bat migratory routes is critical in the face of increasing threats from climate change and wind turbines that might decrease migratory survival. We employ a new modeling approach for bat migration, network modeling, to simulate migratory routes between winter habitat in southern Mexico and summer breeding habitat in northern Mexico and the southwestern United States. We use the model to identify key migratory routes and the roosts of greatest conservation value to the overall population. We measure roost importance by the degree to which the overall bat population declined when the roost was removed from the model. The major migratory routes—those with the greatest number of migrants—were between winter habitat in southern Mexico and summer breeding roosts in Texas and the northern Mexican states of Sonora and Nuevo Leon. The summer breeding roosts in Texas, Sonora, and Nuevo Leon were the most important for maintaining population numbers and network structure – these are also the largest roosts. This modeling approach contributes to conservation efforts by identifying the most influential areas for bat populations, and can be used as a tool to improve our understanding of bat migration for other species. We anticipate this approach will help direct coordination of habitat protection across borders.

Quantification of the economic value provided by migratory species can aid in targeting management efforts and funding to locations yielding the greatest benefits to society and species conservation. Here we illustrate a key step in this process by estimating hunting and birding values of the northern pintail (Anas acuta) within primary breeding and wintering habitats used during the species’ annual migratory cycle in North America. We used published information on user expenditures and net economic values (consumer surplus) for recreational viewing and hunting to determine the economic value of pintail-based recreation in three primary breeding areas and two primary wintering areas. Summed expenditures and consumer surplus for northern pintail viewing were annually valued at $70M, and annual sport hunting totaled $31M (2014 USD). Expenditures for viewing ($42M) were more than twice as high than those for hunting ($18M). Estimates of consumer surplus, defined as the amount consumers are willing to pay above their current expenditures, were $15M greater for viewing ($28M) than for hunting ($13M). We discovered substantial annual consumer surplus ($41M) available for pintail conservation from birders and hunters. We also found spatial differences in economic value among the primary regions used by pintails, with viewing generally valued more in breeding regions than in wintering regions and the reverse being true for hunting. The economic value of pintail-based recreation in the Western wintering region ($26M) exceeded that in any other region by at least a factor of three. Our approach of developing regionally explicit economic values can be extended to other taxonomic groups, and is particularly suitable for migratory game birds because of the availability of large amounts of data. When combined with habitat-linked population models, regionally explicit values could inform development of more effective conservation finance and policy mechanisms to enhance

Regulatory T cells (Tregs) are important in controlling skin inflammation, an effect dependent on their ability to home to this organ. However, little is known regarding their behavior in the skin. In this study, we used multiphoton imaging in Foxp3-GFP mice to examine the behavior of endogenous Tregs in resting and inflamed skin. Although Tregs were readily detectable in the uninflamed dermis, most were nonmotile. Induction of contact sensitivity increased the proportion of motile Tregs, and also induced Treg recruitment. This response was significantly blunted in mice challenged with an irrelevant hapten, or by inhibition of effector cell recruitment, indicating a role for T cell-dependent inflammation in induction of Treg migration. Moreover, induction of Treg migration was inhibited by local injection of a CCR4 antagonist, indicating a role for CCR4 in this response. Exposure of naive mice to hapten also induced an increase in the proportion of migratory Tregs, demonstrating that innate signals can also induce Treg migration. Simultaneous examination of the migration of CD4⁺ effector cells and Tregs in the same region of uninflamed skin demonstrated that effector cells behaved differently, being uniformly highly migratory. These findings indicate that Treg behavior in skin differs from that of CD4⁺ effector cells, in that only a low proportion of Tregs is migratory under resting conditions. However, in response to both adaptive and innate inflammation, the proportion of migratory Tregs increases, raising the possibility that this response is important in multiple forms of skin inflammation.

Full Text Available Low pathogenic avian influenza virus can mutate to a highly pathogenic strain that causes severe clinical signs in birds and humans. Migratory waterfowl, especially ducks, are considered the main hosts of low pathogenic avian influenza virus, but the role of geese in dispersing the virus over long-distances is still unclear. We collected throat and cloaca samples from three goose species, Bean goose (Anser fabalis, Barnacle goose (Branta leucopsis and Greater white-fronted goose (Anser albifrons, from their breeding grounds, spring stopover sites, and wintering grounds. We tested if the geese were infected with low pathogenic avian influenza virus outside of their wintering grounds, and analysed the spatial and temporal patterns of infection prevalence on their wintering grounds. Our results show that geese were not infected before their arrival on wintering grounds. Barnacle geese and Greater white-fronted geese had low prevalence of infection just after their arrival on wintering grounds in the Netherlands, but the prevalence increased in successive months, and peaked after December. This suggests that migratory geese are exposed to the virus after their arrival on wintering grounds, indicating that migratory geese might not disperse low pathogenic avian influenza virus during autumn migration.

Full Text Available Globally-minded teachers often beget globally-minded students. The same relationship seems to hold true for multiculturalism; teachers who are committed to multiculturalism often nudge students toward the same commitment. Global citizenship and multicultural education share a strong bond. Yet, in the field of social studies teacher preparation, the bond between global competencies and multiculturalism often seems permeable and quite fragile. In the context of multicultural education in the United States, teachers engage with issues of privilege, power, and oppression but with a heavy US-centric focus. The article contends that the predominant United States’ focus of multiculturalism limits the opportunities to engage the global: global competencies, global voices, and global citizenship. The article seeks to wed multiculturalism and global education. It does so by introducing and explaining Critical Cosmopolitan Theory (Byker, 2013, which is a theoretical framework to guide the preparation of globally competent and culturally responsive teacher candidates. Utilizing findings from an artifact analysis study of teacher candidates (n=51, the article discusses ways to assist teacher candidates in their development of becoming Critically Cosmopolitan citizens who embrace social justice by being informed by the global and multicultural.

Anthropology was a new field of study when Kant first began lecturing on it in 1772, and Kant himself was the first academic to teach regular courses in this area. As is well known, his own approach to anthropology is self-described as 'pragmatic', and Kant's pragmatic anthropology differs markedly from the anthropologies that other early contributors to the new discipline were advocating. In this essay I focus on a fundamental feature of Kant's anthropology that has been under-appreciated in previous discussions; namely, the particular conception of human nature that he believes anthropology, when pursued properly, leads to. I call this conception a cosmopolitan conception of human nature. In addition to establishing the central importance of this idea for Kant's project in anthropology, I also try in this essay to unravel some of its ambiguities and tensions as well as to highlight its underlying moral motives. The cosmopolitan conception of human nature that is central to Kant's anthropology is a further indication of the significance of his anthropology for ethics.

Major dengue epidemics have been observed in the Indian subcontinent since the 1980s and have occurred with increased hospitalizations and mortality. In 2011, the first major epidemic of dengue occurred in Lahore, the second largest city in Pakistan, and resulted in 21,685 confirmed cases and 350 deaths. To investigate the possible viral causes for the increased epidemic activity, we determined the predominant serotype and characterized the viruses genetically. Of 50 patients carefully selected as probable dengue fever or dengue hemorrhagic fever, 34 were positive by virologic testing (i.e. PCR and/or virus isolation). DENV-2 was detected in 32 patients and DENV-1 in two. A total of 24 partial and three full DENV genomes were sequenced. Phylogenetic analyses of the capsid (C), pre-membrane (prM), and envelope genes comprising 2500 nucleotides in length indicated that all DENV-2 isolates in Pakistan since 2007 form a monophyletic lineage that is endemic in the country. These viruses were all of the cosmopolitan genotype (IV) and most closely related to viruses isolated in India and Sri Lanka in the past two decades. Phylogenetic analyses of data currently available in GenBank suggest that the Cosmopolitan genotype has diverged into two geographically distinct sub-lineages: sub-lineage IV-a has only been observed in Southeast Asia, China and Oceania, while IV-b is prevalent in the Indian subcontinent. These results highlight the increased diversity of dengue viruses as they spread geographically within the region.
Full Text Available There is, perhaps, no more appropriate exhibition within recent memory to display the ‘cosmopolitan moment’ of Enlightenment art patronage and collecting than Masterpieces from the Hermitage: The Legacy of Catherine the Great. Touted as a ‘sweeping survey of art from the Russian court’, the exhibition provided visitors with the most extraordinary glimpse into to the cosmopolitan taste of Catherine II, who ruled Russia for 34 years, between 1762 and 1796. Her reign spanned the period of Enlightenment and the revolutions that Enlightenment thinking gave rise to in America and France. A frequent correspondent with French philosophes, such as Voltaire and Diderot, she became disillusioned with Enlightenment ideas following the imprisonment and execution of Louis XVI and the violence of the Terror. Her collections, nevertheless, stand as visual evidence of her interest in art, not only as an extension of her grandeur as a ruler, which was typical of the age of absolutism, but also as the material expression of her intellectual curiosity and openness to other cultures.
This paper engages with debates surrounding contemporary cosmopolitanism and the outcomes of cultural encounters. It considers if overseas gap years, often put forward in the UK as a way of becoming a global citizen, enable young Britons to 'broaden their mind'. I explore representations of the people and places encountered during these periods of time out through an analysis of young people's travel blogs. Four key themes are highlighted in these narratives: the exotic place; feeling 'out of place'; the importance and outcomes of local interaction; and the historical legacies that are implicated in constructing places as 'different'. Gappers display a willingness to interact with and gain knowledge about their host communities. Yet as gap years are designed to be distinct from the normal course of things, they also demonstrate the 'difference' of places. This can often result in the reproduction of established ways of representing the Other in order to frame them as meaningful. There is a tension in the narratives between 'globally reflexive' and 'globally reproductive' representations of difference, and I suggest that we might question the development of cosmopolitan attitudes and competencies through undertaking a gap year. © London School of Economics and Political Science 2013.
Full Text Available Human rights are today criticized as not compatible with different cultural values and the debate has circulated around Asian values and Islamic values as in dichotomy with human rights as universal ethics (Ignatieff, 2003. The theoretical dichotomy between universality and particularity is questioned pragmatically in this paper through a historical study. The working process of drafting the Universal Declaration of Human Rights (UDHR in 1946-48, which included thousands of people, is explored as a cosmopolitan space in which individuals from different cultural contexts met to negotiate human rights through cultural narratives. The process where particular values were negotiated with universal notion on human rights resulted in a common proclamation (UDHR without a common philosophical or ideological ground. This paper puts forth a thesis that human rights discourse can work as a cosmopolitan space, in which particular value systems meet in processes characterized by conflict and cohesion. Hence human rights can be understood as a master narrative compatible with different conflicting cultural narratives (Gibson & Somers, 1994.
Full Text Available In this paper I discuss a Kantian conception of cosmopolitan education. It suggests that we pursue the highest good – an object of morality – in the world together, and requires that we acknowledge the value of freedom, render ourselves both efficacious and autonomous in practice, cultivate our judgment, and unselfishly co-operate in the co-ordination and fulfilment of our morally permissible ends. Now, such an accomplishment is one of the most difficult challenges, and may not be achieved in our time, if ever. In the first part of the paper I show that we, according to Kant, have to interact with each other, and comply with the moral law in the quest of general happiness, not merely personal happiness. In the second part, I argue that a cosmopolitan design of teacher education in Kantian terms can establish moral character, even though good moral character is ultimately the outcome of free choice. Such a design can do so by optimizing the freedom of those concerned to set and pursue their morally permissible ends, and to cultivate their judgment through the use of examples. This requires, inter alia, that they be enabled, and take responsibility, to think for themselves, in the position of everyone else, and consistently; and to strengthen their virtue or self-mastery to comply, in practice, with the moral law.

Full Text Available IVF in the United Arab Emirates (UAE is decidedly cosmopolitan, catering to an international clientele who are attracted to Dubai as a booming global city and an emerging medical tourism hub. Yet this Emirati state-sponsored project of medical cosmopolitanism exists in tension with another state-sponsored project, called emiratization. Emiratization is an attempt by the UAE government to prioritize the needs of Emiratis. In this article, the emiratization of the UAE’s IVF sector is explored. Since the mid-2000s, the Emirati IVF sector has undergone a series of profound transformations, involving the indigenization-qua-emiratization of IVF services in the country. Two main aspects of IVF emiratization are examined. The first involves the Emirati government’s brief experiment with IVF public financing, which started off as a generous IVF subsidization programme for all infertile couples, but ended up solidifying preferential treatment for local Emiratis. The second is the 2010 passage of UAE Federal Law No. 11, which now stands as one of the world’s most restrictive pieces of assisted reproduction legislation. Which now stands as one of the world's most restrictive pieces of assisted reproduction legislation and has fundamentally altered the landscape of IVF in the country.

Conserving migratory species requires protecting connected habitat along the pathways they travel. Despite recent improvements in tracking animal movements, migratory connectivity remains poorly resolved at a population level for the vast majority of species, thus conservation prioritization is hampered. To address this data limitation, we developed a novel approach to spatial prioritization based on a model of potential connectivity derived from empirical data on species abundance and distance traveled between sites during migration. We applied the approach to migratory shorebirds of the East Asian-Australasian Flyway. Conservation strategies that prioritized sites based on connectivity and abundance metrics together maintained larger populations of birds than strategies that prioritized sites based only on abundance metrics. The conservation value of a site therefore depended on both its capacity to support migratory animals and its position within the migratory pathway; the loss of crucial sites led to partial or total population collapse. We suggest that conservation approaches that prioritize sites supporting large populations of migrants should, where possible, also include data on the spatial arrangement of sites. © 2016 Society for Conservation Biology.
Full Text Available Migratory birds have evolved elaborate physiological adaptations to travelling, the implications for their susceptibility to avian influenza are however unknown. Three groups of stonechats (Saxicola torquata from (I strongly migrating, (II weakly migrating and (III non-migrating populations were experimentally infected with HPAIV H5N1. The different bird groups of this insectivorous passerine species were infected in autumn, when the migrating populations clearly exhibit migratory restlessness. Following infection, all animals succumbed to the disease from 3 through 7 days post inoculation. Viral shedding, antigen distribution in tissues, and survival time did not differ between the three populations. However, notably, endothelial tropism of the HPAIV infection was exclusively seen in the group of resident birds. In conclusion, our data document for the first time the high susceptibility of an insectivorous passerine species to H5N1 infection, and the epidemiological role of these passerine birds is probably limited due to their high sensitivity to HPAIV H5N1 infection. Despite pronounced inherited differences in migratory status, the groups were generally indistinguishable in their susceptibility, survival time, clinical symptoms and viral shedding. Nevertheless, the migratory status partly influenced pathogenesis in the way of viral tropism.

Full Text Available The presence of neural stem cells in the adult brain is currently widely accepted and efforts are made to harness the regenerative potential of these cells. The dentate gyrus of the hippocampal formation, and the subventricular zone (SVZ of the anterior lateral ventricles, are considered the main loci of adult neurogenesis. The rostral migratory stream (RMS is the structure funneling SVZ progenitor cells through the forebrain to their final destination in the olfactory bulb. Moreover, extensive proliferation occurs in the RMS. Some evidence suggest the presence of stem cells in the RMS, but these cells are few and possibly of limited differentiation potential. We have recently demonstrated the specific expression of the cytoskeleton linker protein radixin in neuroblasts in the RMS and in oligodendrocyte progenitors throughout the brain. These cell populations are greatly altered after intracerebroventricular infusion of epidermal growth factor (EGF. In the current study we investigate the effect of EGF infusion on the rat RMS. We describe a specific increase of radixin(+/Olig2(+ cells in the RMS. Negative for NG2 and CNPase, these radixin(+/Olig2(+ cells are distinct from typical oligodendrocyte progenitors. The expanded Olig2(+ population responds rapidly to EGF and proliferates after only 24 hours along the entire RMS, suggesting local activation by EGF throughout the RMS rather than migration from the SVZ. In addition, the radixin(+/Olig2(+ progenitors assemble in chains in vivo and migrate in chains in explant cultures, suggesting that they possess migratory properties within the RMS. In summary, these results provide insight into the adaptive capacity of the RMS and point to an additional stem cell source for future brain repair strategies.

Moreover, Transcontinental subgroup A and the Japanese subgroup B were reported among blood donors from the nonendemic central region of the country. We carried out the first HTLV-1 phylogenetic study in individuals residing in Buenos Aires capital city. Phylogenetic analysis performed on the LTR region showed that all 44 new strains clustered within the Cosmopolitan subtype, with 42 (95.4%) belonging to Transcontinental subgroup A. Of them, 20 (45.5%) strains grouped in the large Latin American cluster and 4 (9.1%) in the small Latin American cluster. The majority of them belonged to individuals of nonblack origin, grouped with Amerindian strains. Three (6.8%) were closely related to South African references and two monophyletic clusters including only HIV/HTLV-1 coinfected individuals were observed. Interestingly, two (4.5%) new sequences (divergent strains) branched off from all five known Cosmopolitan subgroups in a well-supported clade. In summary, these findings show that HTLV-1 Cosmopolitan subtype Transcontinental subgroup A is infecting residents of Buenos Aires, a nonendemic area of Argentina, and confirm the introduction of divergent strains in the country.

Full Text Available In terms of modern life, consumers have an increasing number of options when it comes to choosing a restaurant when they do not wish to eat at their homes. Fast food restaurants represent one of those options. In addition to domestic fast food restaurants, the development of global restaurant chains is also noticeable. The purpose of this paper is to identify the factors that affect the evaluations of products and services and the intentions of users in terms of using the services of fast food restaurants. In relation to that, it is important to analyze the factor of cosmopolitanism and tradition. Cosmopolitanism, as the willingness of people to cooperate with other cultures and tradition, and tradition, as a reflection of respect for the customs and ideas that are imposed on individuals by their culture or religion, affect consumers’ intentions and their willingness to use the services of foreign fast food restaurants. In accordance with that, the purpose of this research study is to determine if and how cosmopolitanism and tradition affect the evaluations of products and services and consumers’ intention concerning foreign restaurant chains and domestic fast food restaurants of both the local and the family types. The results of the conducted empirical research show that cosmopolitanism positively affects the evaluations of the products and services of foreign restaurants and that tradition positively affects the evaluations of the products and services of domestic fast food restaurants.

Migration allows animals to live in resource-rich but seasonally variable environments. Because of the costs of migration, there is selective pressure to capitalize on variation in weather to optimize migratory performance. To test the degree to which migratory performance (defined as speed of migration) of Golden Eagles (Aquila chrysaetos) was determined by age- and season-specific responses to variation in weather, we analyzed 1,863 daily tracks (n = 83 migrant eagles) and 8,047 hourly tracks (n = 83) based on 15 min GPS telemetry data from Golden Eagles and 277 hourly tracks based on 30 s data (n = 37). Spring migrant eagles traveled 139.75 ± 82.19 km day−1 (mean ± SE; n = 57) and 25.59 ± 11.75 km hr−1 (n = 55). Autumn migrant eagles traveled 99.14 ± 59.98 km day−1 (n = 26) and 22.18 ± 9.18 km hr−1 (n = 28). Weather during migration varied by season and by age class. During spring, best-supported daily and hourly models of 15 min data suggested that migratory performance was influenced most strongly by downward solar radiation and that older birds benefited less from flow assistance (tailwinds). During autumn, best-supported daily and hourly models of 15 min data suggested that migratory performance was influenced most strongly by south–north winds and by flow assistance, again less strongly for older birds. In contrast, models for hourly performance based on data collected at 30 s intervals were not well described by a single model, likely reflecting eagles' rapid responses to the many weather conditions they experienced. Although daily speed of travel was similar for all age classes, younger birds traveled at faster hourly speeds than did adults. Our analyses uncovered strong, sometimes counterintuitive, relationships among weather, experience, and migratory flight, and they illustrate the significance of factors other than age in determining migratory performance.

Populations of migratory birds differ in their direction of migration with neighbouring populations often migrating in divergent directions separated by migratory divides. A total of 26% of 103 passerine bird species in Europe had migratory divides that were located disproportionately often along a longitudinal gradient in Central Europe, consistent with the assumption of a Quaternary glacial origin of such divides in the Iberian and Balkan peninsulas followed by recolonization. Given that studies have shown significant genetic differentiation and reduced gene flow across migratory divides, we hypothesized that an absence of migratory divides would result in elevated rates of gene flow and hence a reduced level of local adaptation. In a comparative study, species with migratory divides had larger population sizes and population densities and longer dispersal distances than species without migratory divides. Species with migratory divides tended to be habitat generalists. Bird species with migratory divides had higher richness of blood parasites and higher growth rates of Staphylococcus on their eggs during the incubation period. There was weaker cell-mediated immunity in adults and stronger cell lysis in species with migratory divides. These findings may suggest that migratory divides constitute barriers to dispersal with consequences for ecology and evolution of distributions, population sizes, habitats and parasite-host interactions. They also suggest that migratory divides may play a role in local adaptation in host-parasite interactions. © 2011 The Authors.

In the psychological sciences, mindfulness practices are increasingly being used, studied, and theorized, but their indigenous theoretical foundations in Buddhist accounts of the dynamics and psychology of personal identity tend to be overlooked. This situation is mirrored in the discipline of philosophy: here, Buddhist views on personal identity are beginning to draw attention, but almost invariably in a way which entirely blanks out the role of mindfulness practices in cultivating Buddhist insights on selfhood. The aggregate result is a failure, in the West, to reflect upon and seriously consider Buddhist theory and Buddhist practice in an integrated, holistic fashion. In its effort to overcome the compartmentalization of Buddhist theory (in philosophy) versus Buddhist practice (in psychology) and to embrace the challenges this might pose to fundamental Western beliefs about the self, this paper is intended both as a plea for and an exercise in greater, more venturesome cosmopolitanism. © The Author(s) 2015.

Full Text Available According to David Miller, we have stronger obligations towards our co-nationals than we have towards non-nationals. While a principle of equality governs our obligations of justice within the nation-state, our obligations towards non-nationals are governed by a weaker principle of sufficiency. In this paper, I critically assess Miller's objection to a traditional argument for global egalitarianism, according to which nationalist and other deviations from equality rely on factors that are arbitrary from a moral point of view. Then I critically discuss Miller's claim that there is no culturally neutral currency with respect to which we may reasonably claim that people should be equally well off on a global scale. Furthermore, I critically discuss Miller's claim that cosmopolitanism undermines national responsibility. And finally, I turn to Miller's own sufficientarian account of global justice and argue that it exhibits too little concern for the plight of the globally worse off.

Full Text Available Major dengue epidemics have been observed in the Indian subcontinent since the 1980s and have occurred with increased hospitalizations and mortality. In 2011, the first major epidemic of dengue occurred in Lahore, the second largest city in Pakistan, and resulted in 21,685 confirmed cases and 350 deaths. To investigate the possible viral causes for the increased epidemic activity, we determined the predominant serotype and characterized the viruses genetically. Of 50 patients carefully selected as probable dengue fever or dengue hemorrhagic fever, 34 were positive by virologic testing (i.e. PCR and/or virus isolation. DENV-2 was detected in 32 patients and DENV-1 in two. A total of 24 partial and three full DENV genomes were sequenced. Phylogenetic analyses of the capsid (C, pre-membrane (prM, and envelope genes comprising 2500 nucleotides in length indicated that all DENV-2 isolates in Pakistan since 2007 form a monophyletic lineage that is endemic in the country. These viruses were all of the cosmopolitan genotype (IV and most closely related to viruses isolated in India and Sri Lanka in the past two decades. Phylogenetic analyses of data currently available in GenBank suggest that the Cosmopolitan genotype has diverged into two geographically distinct sub-lineages: sub-lineage IV-a has only been observed in Southeast Asia, China and Oceania, while IV-b is prevalent in the Indian subcontinent. These results highlight the increased diversity of dengue viruses as they spread geographically within the region.
Full Text Available Basal metabolic rate (BMR represents the minimum maintenance energy requirement of an endotherm and has far-reaching consequences for interactions between animals and their environments. Avian BMR exhibits considerable variation that is independent of body mass. Some long-distance migrants have been found to exhibit particularly high BMR, traditionally interpreted as being related to the energetic demands of long-distance migration. Here we use a global dataset to evaluate differences in BMR between migrants and non-migrants, and to examine the effects of environmental variables. The BMR of migrant species is significantly higher than that of non-migrants. Intriguingly, while the elevated BMR of migrants on their breeding grounds may reflect the metabolic machinery required for long-distance movements, an alternative (and statistically stronger explanation is their occupation of predominantly cold high-latitude breeding areas. Among several environmental predictors, average annual temperature has the strongest effect on BMR, with a 50% reduction associated with a 20 degrees C gradient. The negative effects of temperature variables on BMR hold separately for migrants and non-migrants and are not due their different climatic associations. BMR in migrants shows a much lower degree of phylogenetic inertia. Our findings indicate that migratory tendency need not necessarily be invoked to explain the higher BMR of migrants. A weaker phylogenetic signal observed in migrants supports the notion of strong phenotypic flexibility in this group which facilitates migration-related BMR adjustments that occur above and beyond environmental conditions. In contrast to the findings of previous analyses of mammalian BMR, primary productivity, aridity or precipitation variability do not appear to be important environmental correlates of avian BMR. The strong effects of temperature-related variables and varying phylogenetic effects reiterate the importance of

Otolith microchemistry was applied to quantify migratory variation and the proportion of native Caribbean stream fishes that undergo full or partial marine migration. Strontium and barium water chemistry in four Puerto Rico, U.S.A., rivers was clearly related to a salinity gradient; however, variation in water barium, and thus fish otoliths, was also dependent on river basin. Strontium was the most accurate index of longitudinal migration in tropical diadromous fish otoliths. Among the four species examined, bigmouth sleeper Gobiomorus dormitor, mountain mullet Agonostomus monticola, sirajo goby Sicydium spp. and river goby Awaous banana, most individuals were fully amphidromous, but 9-12% were semi-amphidromous as recruits, having never experienced marine or estuarine conditions in early life stages and showing no evidence of marine elemental signatures in their otolith core. Populations of one species, G. dormitor, may have contained a small contingent of semi-amphidromous adults, migratory individuals that periodically occupied marine or estuarine habitats (4%); however, adult migratory elemental signatures may have been confounded with those related to diet and physiology. These findings indicate the plasticity of migratory strategies of tropical diadromous fishes, which may be more variable than simple categorization might suggest.

Full Text Available Migrating birds may respond to a variety of environmental cues in order to time migration. During the migration season nocturnally migrating songbirds may migrate or stop-over at their current location, and when migrating they may vary the rate or distance of migration on any given night. It has long been known that a variety of weather-related factors including wind speed and direction, and temperature, are correlated with migration in free-living birds, however these variables are often correlated with each other. In this study we experimentally manipulated temperature to determine if it would directly modulate nocturnal migratory restlessness in songbirds. We experimentally manipulated temperature between 4, 14, and 24°C and monitored nocturnal migratory restlessness during autumn in white-throated sparrows (Zonotrichia albicollis. White-throated sparrows are relatively shortdistance migrants with a prolonged autumnal migration, and we thus predicted they might be sensitive to weatherrelated cues when deciding whether to migrate or stopover. At warm temperatures (24°C none of the birds exhibited migratory restlessness. The probability of exhibiting migratory restlessness, and the intensity of this restlessness (number of infra-red beam breaks increased at cooler (14°C, 4°C temperatures. These data support the hypothesis that one of the many factors that birds use when making behavioural decisions during migration is temperature, and that birds can respond to temperature directly independently of other weather-related cues.

This article discusses the conservation challenges of volant migratory transborder species and conservation governance primarily in North America. Many migratory species provide ecosystem service benefits to society. For example, insectivorous bats prey on crop pests and reduce the need for pesticides; birds and insects pollinate food plants; and birds afford recreational opportunities to hunters and birdwatchers. Migration is driven by the seasonal availability of resources; as resources in one area become seasonally scarce, individuals move to locations where resources have become seasonally abundant. The separation of the annual lifecycle means that species management and governance is often fractured across international borders. Because migratory species depend on habitat in different locations, their ability to provide ecosystem services in one area depends on the spatial subsidies, or support, provided by habitat and ecological processes in other areas. This creates telecouplings, or interconnections across geographic space, of areas such that impacts to the habitat of a migratory species in one location will affect the benefits enjoyed by people in other locations. Information about telecoupling and spatial subsidies can be used to craft new governance arrangements such as Payment for Ecosystem Services programs that target specific stakeholder groups and locations. We illustrate these challenges and opportunities with three North American case studies: the Duck Stamp Program, Mexican free-tailed bats (Tadarida brasiliensis mexicana), and monarch butterflies (Danaus plexippus).

Migration is suspected to increase the risk for psychological distress for those who enter a new cultural environment. We investigated the association between sociodemographic characteristics, premigratory and migratory factors and psychological distress in rural-to-urban migrants just after migration and after resettlement. Data from the cross-sectional sib-pair designed Indian Migration Study (IMS, 2005-2007) were used. The analysis focused on 2112 participants aged ≥18 years from the total IMS sample ( n = 7067) who reported being migrant. Psychological distress was assessed based on the responses of the 7-questions in a five-point scale, where the respondents were asked to report about their feelings now and also asked to recall these feelings when they first migrated. The associations were analyzed using multiple logistic regression models. High prevalence of psychological distress was found just after migration (7.3%; 95% confidence interval [CI]: 6.2-8.4) than after settlement (4.7%; 95% CI: 3.8-5.6). Push factors as a reason behind migration and not being able to adjust in the new environment were the main correlates of psychological distress among both the male and female migrants, just after migration. Rural-urban migration is a major phenomenon in India and given the impact of premigratory and migratory related stressors on mental health, early intervention could prevent the development of psychological distress among the migrants.

A number of terrestrial bird species that breed in North America cross the Atlantic Ocean during autumn migration when travelling to their non-breeding grounds in the Caribbean or South America. When conducting oceanic crossings, migratory birds tend to associate with mild or supportive winds, whose speed and direction may change under global warming. The implications of these changes for transoceanic migratory bird populations have not been addressed. We used occurrence information from eBird (1950-2015) to estimate the geographical location of population centres at a daily temporal resolution across the annual cycle for 10 transatlantic migratory bird species. We used this information to estimate the location and timing of autumn migration within the transatlantic flyway. We estimated how prevailing winds are projected to change within the transatlantic flyway during this time using daily wind speed anomalies (1996-2005 and 2091-2100) from 29 Atmosphere-Ocean General Circulation Models implemented under CMIP5. Autumn transatlantic migrants have the potential to encounter strong westerly crosswinds early in their transatlantic journey at intermediate and especially high migration altitudes, strong headwinds at low and intermediate migration altitudes within the Caribbean that increase in strength as the season progresses, and weak tailwinds at intermediate and high migration altitudes east of the Caribbean. The CMIP5 simulations suggest that, during this century, the likelihood of autumn transatlantic migrants encountering strong westerly crosswinds will diminish. As global warming progresses, the need for species to compensate or drift under the influence of strong westerly crosswinds during the initial phase of their autumn transatlantic journey may be diminished. Existing strategies that promote headwind avoidance and tailwind assistance will likely remain valid. Thus, climate change may reduce time and energy requirements and the chance of mortality or

Between one and two million migratory agricultural workers (MAWs), primarily from Mexico and Central America, leave their homes each year to plant, cultivate, harvest and pack fruits, vegetables, and nuts in the USA. While in the USA, most lack health insurance, a permanent residence, and a regular healthcare provider. Publications over the past two decades in the USA have reported that a majority of MAWs encounter barriers to receiving medical services. Migratory agricultural workers experience high rates of occupational illness and injury. Poor access to medical care continues to exacerbate health problems among members of this population related to their working environments. In most studies concerning healthcare access issues for this population, researchers collected their information from healthcare service providers; rarely have they included input from migratory agricultural workers. This study was different in that opinions about healthcare access issues were collected directly from MAWs. The primary purpose of this study was to describe issues related to barriers associated with the delivery of healthcare services to migratory agricultural workers. A secondary purpose was to suggest strategies for reducing these barriers. In this study, data from focus group sessions were used to develop a survey questionnaire. Four certified bilingual interpreters were trained to administer the questionnaire. A total of 157 usable questionnaires were returned from MAWs living in employer-provided camps in Northwest Ohio. The statistical analyses were primarily descriptive. The most significant barriers hampering access to medical services among the 157 respondents were cost (n=113; 72.0%), crop demands (n=102; 65.0%), the lack of an interpreter (n=98; 62.4%), travel distance (n=88; 56.1%) and transportation (n=82; 52.2%). Approximately half (n=82; 52.2%) said that they had access to transportation for traveling to a medical clinic. As a group, respondents were willing to
Full Text Available Migratory waterfowl of the world are the natural reservoirs of influenza viruses of all known subtypes. However, it is unknown whether these waterfowl perpetuate highly pathogenic (HP H5 and H7 avian influenza viruses. Here we report influenza virus surveillance from 2001 to 2006 in wild ducks in Alberta, Canada, and in shorebirds and gulls at Delaware Bay (New Jersey, United States, and examine the frequency of exchange of influenza viruses between the Eurasian and American virus clades, or superfamilies. Influenza viruses belonging to each of the subtypes H1 through H13 and N1 through N9 were detected in these waterfowl, but H14 and H15 were not found. Viruses of the HP Asian H5N1 subtypes were not detected, and serologic studies in adult mallard ducks provided no evidence of their circulation. The recently described H16 subtype of influenza viruses was detected in American shorebirds and gulls but not in ducks. We also found an unusual cluster of H7N3 influenza viruses in shorebirds and gulls that was able to replicate well in chickens and kill chicken embryos. Genetic analysis of 6,767 avian influenza gene segments and 248 complete avian influenza viruses supported the notion that the exchange of entire influenza viruses between the Eurasian and American clades does not occur frequently. Overall, the available evidence does not support the perpetuation of HP H5N1 influenza in migratory birds and suggests that the introduction of HP Asian H5N1 to the Americas by migratory birds is likely to be a rare event.

Since the landmark Santa Rosalia paper by Hutchinson, niche theory addresses the determinants of biodiversity in terms of both environmental and biological aspects. Disentangling the role of habitat filtering and interactions with other species is critical for understanding microbial ecology. Macroscopic biogeography explores hypothetical ecological interactions through the analysis of species associations. These methods have started to be incorporated into microbial ecology relatively recently, due to the inherent experimental difficulties and the coarse grained nature of the data. Here we investigate the influence of environmental preferences and ecological interactions in the tendency of bacterial taxa to either aggregate or segregate, using a comprehensive dataset of bacterial taxa observed in a wide variety of environments. We assess significance of taxa associations through a null model that takes into account habitat preferences and the global distribution of taxa across samples. The analysis of these associations reveals a surprisingly large number of significant aggregations between taxa, with a marked community structure and a strong propensity to aggregate for cosmopolitan taxa. Due to the coarse grained nature of our data we cannot conclusively reject the hypothesis that many of these aggregations are due to environmental preferences that the null model fails to reproduce. Nevertheless, some observations are better explained by ecological interactions than by habitat filtering. In particular, most pairs of aggregating taxa co-occur in very different environments, which makes it unlikely that these associations are due to habitat preferences, and many are formed by cosmopolitan taxa without well defined habitat preferences. Moreover, known cooperative interactions are retrieved as aggregating pairs of taxa. As observed in similar studies, we also found that phylogenetically related taxa are much more prone to aggregate than to segregate, an observation

Dengue virus infection was diagnosed in six Israeli travellers returning from the Seychelles in April 2017. Phylogenetic analysis identified identical sequences belonging to the Cosmopolitan genotype of dengue virus type 2 in all samples sequenced, thus providing evidence for a probable dengue type 2 outbreak in the Seychelles. This report further demonstrates the role of travellers as sentinels for arboviral infections, especially in countries with limited diagnostic capabilities.

Full Text Available The recent turn to a transnational American literary cosmopolitanism, coupled with efforts to move beyond what Paul Gilroy calls “ethnic absolutes,” have generated a resurgence of interest in W. E. B. Du Bois’s 1928 romance novel, Dark Princess. In addition, the last two decades have witnessed tentative movements to bridge the gap between American ethnic studies and postcolonial studies. This essay begins with the premise that there are compelling reasons to reread Dark Princess in light of twenty-first century debates about postcolonialism and cosmopolitanism, but it also points to some of the hazards of reading the novel outside of the social and aesthetic politics of the decades between the two world wars. The main part of this paper is an attempt to address the gendered and sexualized body politics of Du Bois’s aesthetic practices through an analysis of his essay “Criteria of Negro Art” and his novel Dark Princess. Allusions in the novel to the fourth-century BCE Indian political philosopher Kautilya and his treatise Arthasâstra suggests that Du Bois’s naming of his princess, Kautilya, was neither accidental nor insignificant. This trans/gendering of Kautilya speaks to a gender and sexual politics inherent to German theories of the aesthetic, to which Du Bois remained wedded. Scholarly fantasies of cosmopolitanism tend to ignore the extent to which such fantasies depend upon ideologies of family and the reproductive bodies of women.

Regional migratory osteoporosis is an uncommon self-limiting disease characterized by an arthralgia which migrates between the weight-bearing joints of the lower limb. The radiological features of the disease obtained by conventional radiography, CT, MRI and radionuclide scintigraphy are illustrated by means of five case reports. These range from the most common presentation of sequential, proximal to distal spread in the lower limb to the rare intra-articular form, and disease involving the axial skeleton is also recognized. Clinical and radiographical features often overlap with those of diseases such as transient osteoporosis of the hip and transient bone marrow oedema syndrome, which is reflected in confusing terminology. Histological sampling is usually unnecessary; the radiological features are characteristic and the histological findings are not specific. Regional migratory osteoporosis is associated with systemic osteoporosis. This association is probably under-recognized, and has implications for the pathophysiology of the disease and for treatment

The annual return of beluga whales, Delphinapterus leucas, to traditional seasonal locations across the Arctic may involve migratory culture, while the convergence of discrete summering aggregations on common wintering grounds may facilitate outbreeding. Natal philopatry and cultural inheritance, however, has been difficult to assess as earlier studies were of too short a duration, while genetic analyses of breeding patterns, especially across the beluga’s Pacific range, have been hampered by inadequate sampling and sparse information on wintering areas. Using a much expanded sample and genetic marker set comprising 1,647 whales, spanning more than two decades and encompassing all major coastal summering aggregations in the Pacific Ocean, we found evolutionary-level divergence among three geographic regions: the Gulf of Alaska, the Bering-Chukchi-Beaufort Seas, and the Sea of Okhotsk (Φst = 0.11–0.32, Rst = 0.09–0.13), and likely demographic independence of (Fst-mtDNA = 0.02–0.66), and in many cases limited gene flow (Fst-nDNA = 0.0–0.02; K = 5–6) among, summering groups within regions. Assignment tests identified few immigrants within summering aggregations, linked migrating groups to specific summering areas, and found that some migratory corridors comprise whales from multiple subpopulations (PBAYES = 0.31:0.69). Further, dispersal is male-biased and substantial numbers of closely related whales congregate together at coastal summering areas. Stable patterns of heterogeneity between areas and consistently high proportions (~20%) of close kin (including parent-offspring) sampled up to 20 years apart within areas (G = 0.2–2.9, p>0.5) is the first direct evidence of natal philopatry to migration destinations in belugas. Using recent satellite telemetry findings on belugas we found that the spatial proximity of winter ranges has a greater influence on the degree of both individual and genetic exchange than summer ranges (rwinter-Fst-mtDNA = 0

Moult is one of the most costly activities in the annual cycle of birds and most avian species separate moult from other energy-demanding activities, such as migration. To this end, young birds tend to undergo the first post-juvenile moult before the onset of migration, but in some species the time window for the pre-migratory feather replacement is too narrow. We hypothesized that in such species an increased investment in the structural quality of juvenile feathers may allow to retain juvenile plumage throughout the entire migratory period and delay moult until arriving at wintering grounds, thus avoiding a moult-migration overlap. The effect of juvenile plumage quality on the occurrence of moult-migration overlap was studied in a migratory shorebird, the common snipe Gallinago gallinago . Ca. 400 of first-year common snipe were captured during their final stage of autumn migration through Central Europe. The quality of juvenile feathers was assessed as the mass-length residuals of retained juvenile rectrices. Condition of migrating birds was assessed with the mass of accumulated fat reserves and whole-blood hemoglobin concentration. Path analysis was used to disentangle complex interrelationships between plumage quality, moult and body condition. Snipe which grew higher-quality feathers in the pre-fledging period were less likely to initiate moult during migration. Individuals moulting during migration had lower fat loads and hemoglobin concentrations compared to non-moulting birds, suggesting a trade-off in resource allocation, where energetic costs of moult reduced both energy reserves available for migration and resources available for maintenance of high oxygen capacity of blood. The results of this study indicate that a major life-history trade-off in a migratory bird may be mediated by the quality of juvenile plumage. This is consistent with a silver spoon effect, where early-life investment in feather quality affects future performance of birds during

Long-lived migratory animals must balance the cost of current reproduction with their own condition ahead of a challenging migration and future reproduction. In these species, carry-over effects, which occur when events in one season affect the outcome of the subsequent season, may be particularly exacerbated. However, how carry-over effects influence future breeding outcomes and whether (and how) they also affect behaviour during migration and wintering is unclear. Here we investigate carry-over effects induced by a controlled, bidirectional manipulation of the duration of reproductive effort on the migratory, wintering and subsequent breeding behaviour of a long-lived migratory seabird, the Manx shearwater Puffinus puffinus. By cross-fostering chicks of different age between nests, we successfully prolonged or shortened by ∼25% the chick-rearing period of 42 breeding pairs. We tracked the adults with geolocators over the subsequent year and combined migration route data with at-sea activity budgets obtained from high-resolution saltwater-immersion data. Migratory behaviour was also recorded during non-experimental years (the year before and/or two years after manipulation) for a subset of birds, allowing comparison between experimental and non-experimental years within treatment groups. All birds cared for chicks until normal fledging age, resulting in birds with a longer breeding period delaying their departure on migration; however, birds that finished breeding earlier did not start migrating earlier. Increased reproductive effort resulted in less time spent at the wintering grounds, a reduction in time spent resting daily and a delayed start of breeding with lighter eggs and chicks and lower breeding success the following breeding season. Conversely, reduced reproductive effort resulted in more time resting and less time foraging during the winter, but a similar breeding phenology and success compared with control birds the following year, suggesting that

1. Migration is a widespread phenomenon, with powerful ecological and evolutionary consequences. Morphological adaptations to reduce the energetic costs associated with migratory transport are commonly documented for migratory species. However, few studies have investigated whether variation in body morphology can be explained by variation in migratory strategy within a species. 2. We address this question in roach Rutilus rutilus, a partially migratory freshwater fish that migrates from lakes into streams during winter. We both compare body shape between populations that differ in migratory opportunity (open vs. closed lakes), and between individuals from a single population that vary in migratory propensity (migrants and residents from a partially migratory population). Following hydrodynamic theory, we posit that migrants should have a more shallow body depth, to reduce the costs associated with migrating into streams with higher flow conditions than the lakes the residents occupy all year round. 3. We find evidence both across and within populations to support our prediction, with individuals from open lakes and migrants from the partially migratory population having a more slender, shallow-bodied morphology than fish from closed lakes and all-year residents. 4. Our data suggest that a shallow body morphology is beneficial to migratory individuals and our study is one of the first to link migratory strategy and intraspecific variation in body shape. © 2015 The Authors.

Tidal marshes are highly productive ecosystems that support migratory birds as roosting and over-wintering habitats on the Pacific Flyway. Microphytobenthos, or more commonly 'biofilms' contribute significantly to the primary productivity of wetland ecosystems, and provide a substantial food source for macroinvertebrates and avian communities. In this study, biofilms were characterized based on taxonomic classification, density differences, and spectral signatures. These techniques were then applied to remotely sensed images to map biofilm densities and distributions in the South Bay Salt Ponds and predict the carrying capacity of these newly restored ponds for migratory birds. The GER-1500 spectroradiometer was used to obtain in situ spectral signatures for each density-class of biofilm. The spectral variation and taxonomic classification between high, medium, and low density biofilm cover types was mapped using in-situ spectral measurements and classification of EO-1 Hyperion and Landsat TM 5 images. Biofilm samples were also collected in the field to perform laboratory analyses including chlorophyll-a, taxonomic classification, and energy content. Comparison of the spectral signatures between the three density groups shows distinct variations useful for classification. Also, analysis of chlorophyll-a concentrations show statistically significant differences between each density group, using the Tukey-Kramer test at an alpha level of 0.05. The potential carrying capacity in South Bay Salt Ponds is estimated to be 250,000 birds.

The Prairie Pothole Region (PPR) is home to more than 50% of the migratory waterfowl in North America. Although the PPR provides an abundance of temporary and permanent wetlands for nesting and feeding, increases in commodity prices and agricultural drainage practices have led to a trend of wetland drainage. The Northern Shoveler is a migratory dabbling duck species that uses wetland habitats and cultivated croplands in the PPR. Richland County in North Dakota and Roberts County in South Dakota have an abundance of wetlands and croplands and were chosen as the study areas for this research to assess the wetland size and cultivated cropland in relation to hydrologic soil groups for the Northern Shoveler habitat. This study used geographic information system data to analyze Northern Shoveler habitats in association with Natural Resource Conservation Service soil data. Habitats, which are spatially associated with certain hydrologic soil groups, may be at risk of artificial drainage installations because of their proximity to cultivated croplands and soil lacking in natural drainage that may become wet or inundated. Findings indicate that most wetlands that are part of Northern Shoveler habitats were within or adjacent to cultivated croplands. The results also revealed soil hydrologic groups with high runoff potential and low water transmission rates account for most of the soil within the Northern Shoveler‘s wetland and cropland habitats. Habitats near agriculture with high runoff potential are likely to be drained and this has the potential of reducing Northern Shoveler habitat.

In the final decades of the nineteenth century, concern was building about the status of migratory bird populations in North America. In this literature review, we describe how that concern led to a landmark conservation agreement in 1916, between the United States and Great Britain (on behalf of Canada) to conserve migratory birds shared by Canada and the United States. Drawing on published literature and our personal experience, we describe how subsequent enabling acts in both countries gave rise to efforts to better estimate population sizes and distributions, assess harvest rates and demographic impacts, design and fund landscape-level habitat conservation initiatives, and organize necessary political and regulatory processes. Executing these steps required large-scale thinking, unprecedented regional and international cooperation, ingenuity, and a commitment to scientific rigor and adaptive management. We applaud the conservation efforts begun 100 years ago with the Migratory Bird Treaty Convention. The agreement helped build the field of wildlife ecology and conservation in the twentieth century but only partially prepares us for the ecological and social challenges ahead.

In this paper, I look at the way in which a maximin egalitarian theory of justice should deal with the greenhouse effect and its consequences. I adopt both a cosmopolitan and a 'local' approach (in Elster's sense). The paper concentrates on three dimensions of a Kyoto-type international regime raising issues of justice: the determination of a global cap on emissions for a given period, the way in which emission quotas should be distributed among countries for each period, and the questions arising from the tradability of such quotas. Regarding the cap issue, it is subject to both inter-generational and intra-generational constraints of justice. I show that a weak intra-generational principle of compensation is likely to lead to radically demanding implications. As to the initial allocation issue, I look at five possible reasons why egalitarians may want to depart from a population-based allocation among countries. Special attention is devoted to three of them: grand-fathering, the disadvantageous geographical specificities of some countries and historical emissions. I specify the extent to which such a departure from a population-based mode of allocation can be justified on egalitarian grounds. Finally, I look at possible objections to the tradability of such quotas, concluding that they are not sufficient to shift toward non-tradable quotas. (author)

Although communities and schools in North America are increasingly diverse and positioned in a global web, schools continue to adhere to Western norms and the teacher workforce remains largely White, continuing an ideology of collective sameness and conformity. Hybridization of teacher identity and of science teaching are suggested as ways to advance an ethic of solidarity through difference (cosmopolitanism) with science teaching as its vehicle. In this paper, I explore identity hybridization among non-dominant science teachers as they merge identity narratives, or who they are around science and science teaching, with who they are out-of-school. Our attention is focused on their experiences of dis-identification with science in terms of diaspora, or the sense of being taken away from what one knows and values. By generating a creolized approach to science teaching, teachers create possibilities for greater student identification with science in school, which in turn has potential for changing the face of who does science and of science itself.
Full Text Available In the half-century before the Great War, collaborative international ventures in science became increasingly common. The trend, manifested in scientific congresses and attempts to establish agreement on physical units and systems of nomenclature, had important consequences. One was the fear of information overload. How were scientists to keep abreast of the growing volume of books, journals, and reports? How were they to do so in an era without a common language? Responses to these challenges helped to foster new departures in cataloguing, bibliography, and an interest in Esperanto and other constructed languages. By 1914, the responses had also become involved in wider movements that promoted communication as a force for peace. The Great War dealt a severe blow to these cosmopolitan ideals, and the post-war reordering of international science did little to resurrect them. A “national turn” during the 1920s assumed a darker form in the 1930s, as totalitarian regimes in the Soviet Union, Italy, Germany, and Spain associated science ever more closely with national interests. Although the Second World War further undermined the ideal of internationalism in science, the vision of science as part of a world culture open to all soon resurfaced, notably in UNESCO. As an aspiration, it remains with us today, in ventures for universal access to information made possible by digitization and the World Wide Web. The challenge in the twenty-first century is how best to turn aspiration into reality.
Full Text Available During the 90’s, Israel and the Palestinians were unable to reach a Peace agreement and this unsuccessful period led to the production of a new Israeli ethnoscape. With increased Israeli border closures (within the pre-1967 limits to Palestinian workers, the Israeli government had to authorize the entrance of foreign workers from Eastern Europe (Romania, Poland but also from Asia (Thailand, the Philippines. These new “faces” of Israel aroused fears concerning their “settlement” and gradually caused a debate, which underlined the social cleavages of Israel. This debate took on more importance as immigrants from West Africa and South America (pushed to Israel by the globalisation were added to this – first – group of non-Jewish immigrants. These regular and irregular immigrations raised the question about the Jewish identity of the State and at the same time have drawn the limits of an Israeli cosmopolitanism. Using the example of Israel, the aim of this paper is to contribute to knowledge about the forms of emergence of “new cosmopolitanisms” and to critique a concept elaborated to describe the tension existing between national discourse and globalisation.

Full Text Available Drug trafficking has been a ubiquitous crime on the American continent since the 1980s, and addressing it has required international policy to function beyond the physical boundaries of the nation-state, whatever its role is: as a producer, as a go-between for its sale, or as a consumer. The manifestations of drug trafficking are criminal, multiple and incalculable. Its behavior as merchandise, subject to supply and demand, has benefitted from the process of globalization, particularly with the availability of technology and IT, which it has made available in local and regional societies. According to Ulrich Beck, Eduardo Pastrana, Irvin Waller, Antanas Mockus and Ariel Francais, drug trafficking is mainly a globalized product, a successful business, a cosmopolitan risk, and a cultural component that is difficult to eradicate with wartime policies because in Colombia violence is not an accidental product, it is multicausal. To address this phenomenon, the only universal regulators are human rights and civil ethics. DOI: http://dx.doi.org/10.5377/rpsp.v2i0.1193

We compared the effects of water resource development on migratory fish in two North American rivers using a descriptive approach based on four high-level indicators: (1) trends in abundance of Pacific salmon, (2) reliance on artificial production to maintain fisheries, (3) proportion of adult salmon that are wild- versus hatchery-origin, and (4) number of salmon populations needing federal protection to avoid extinction. The two rivers had similar biological and physical features but radically different levels of water resource development: the Fraser River has few dams and all are located in tributaries, whereas the Columbia River has more than 130 large mainstem and tributary dams. Not surprisingly, we found substantial effects of development on salmon in the Columbia River. We related the results to potential effects on migratory fish in the Mekong River where nearly 200 mainstem and tributary dams are installed, under construction, or planned and could have profound effects on its 135 migratory fish species. Impacts will vary with dam location due to differential fish production within the basin, with overall effects likely being greatest from 11 proposed mainstem dams. Minimizing impacts will require decades to design specialized fish passage facilities, dam operations, and artificial production, and is complicated by the Mekong's high diversity and productivity. Prompt action is needed by governments and fisheries managers to plan Mekong water resource development wisely to prevent impacts to the world's most productive inland fisheries, and food security and employment opportunities for millions of people in the region.

Full Text Available Documented fatalities of bats at wind turbines have raised serious concerns about the future impacts of increased wind power development on populations of migratory bat species. However, for most bat species we have no knowledge of the size of populations and their demographic trends, the degree of structuring into discrete subpopulations, and whether different subpopulations use spatially segregated migratory routes. Here, we utilize genetic data from eastern red bats (Lasiurus borealis, one of the species most highly affected by wind power development in North America, to (1 evaluate patterns of population structure across the landscape, (2 estimate effective population size (Ne, and (3 assess signals of growth or decline in population size. Using data on both nuclear and mitochondrial DNA variation, we demonstrate that this species forms a single, panmictic population across their range with no evidence for the historical use of divergent migratory pathways by any portion of the population. Further, using coalescent estimates we estimate that the effective size of this population is in the hundreds of thousands to millions of individuals. The high levels of gene flow and connectivity across the population of eastern red bats indicate that monitoring and management of eastern red bats must integrate information across the range of this species.

Neutral genetic markers are routinely used to define distinct units within species that warrant discrete management. Human-induced changes to gene flow however may reduce the power of such an approach. We tested the efficiency of adaptive versus neutral genetic markers in differentiating temporally divergent migratory runs of Chinook salmon (Oncorhynchus tshawytscha) amid high gene flow owing to artificial propagation and habitat alteration. We compared seven putative migration timing genes to ten microsatellite loci in delineating three migratory groups of Chinook in the Feather River, CA: offspring of fall-run hatchery broodstock that returned as adults to freshwater in fall (fall run), spring-run offspring that returned in spring (spring run), and fall-run offspring that returned in spring (FRS). We found evidence for significant differentiation between the fall and federally listed threatened spring groups based on divergence at three circadian clock genes (OtsClock1b, OmyFbxw11, and Omy1009UW), but not neutral markers. We thus demonstrate the importance of genetic marker choice in resolving complex life history types. These findings directly impact conservation management strategies and add to previous evidence from Pacific and Atlantic salmon indicating that circadian clock genes influence migration timing.

Full Text Available This study investigated the migratory fish spawning within the reservoirs of the Machadinho and Itá dams (upper Uruguay River, Brazil and its relationship to environmental variables. Sampling was conducted in the lotic region of the river in two sites between the dams' reservoirs: Uruguay (main river and Ligeiro (tributary. Sampling included nine consecutive reproductive periods (RP spanning the period from 2001 to 2010 and was conducted at night on the water surface using cylindrical-conical plankton nets (0.5 mm mesh; environmental variables were also recorded. The spawning of the migratory species Salminus brasiliensis, Prochilodus lineatus, and Steindachneridion scriptum was registered: S. brasiliensis and P. lineatus spawned in the tributary river at the end of spring/beginning of summer, during flooding and during periods of high water temperature. Steindachneridion scriptum spawned in the main river at the beginning of spring. The study showed that S. brasiliensis, P. lineatus, and S. scriptum are able to spawn in small lotic river stretches within two reservoirs, but only under very specific and not common environmental conditions.

Documented fatalities of bats at wind turbines have raised serious concerns about the future impacts of increased wind power development on populations of migratory bat species. Yet there is little data on bat population sizes and trends to provide context for understanding the consequences of mortality due to wind power development. Using a large dataset of both nuclear and mitochondrial DNA variation for eastern red bats, we demonstrated that: 1) this species forms a single, panmictic population across their range with no evidence for the historical use of divergent migratory pathways by any portion of the population; 2) the effective size of this population is in the hundreds of thousands to millions; and 3) for large populations, genetic diversity measures and at least one coalescent method are insensitive to even very high rates of population decline over long time scales and until population size has become very small. Our data provide important context for understanding the population-level impacts of wind power development on affected bat species.
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.

In this paper, we introduce a mechanistic model of migratory movement patterns in birds, inspired by ideas and methods from physics. Previous studies have shed light on the factors influencing bird migration but have mainly relied on statistical correlative analysis of tracking data. Our novel method offers a bottom up explanation of population-level migratory movement patterns. It differs from previous mechanistic models of animal migration and enables predictions of pathways and destinations from a given starting location. We define an environmental potential landscape from environmental data and simulate bird movement within this landscape based on simple decision rules drawn from statistical mechanics. We explore the capacity of the model by qualitatively comparing simulation results to the non-breeding migration patterns of a seabird species, the Black-browed Albatross (Thalassarche melanophris). This minimal, two-parameter model was able to capture remarkably well the previously documented migration patterns of the Black-browed Albatross, with the best combination of parameter values conserved across multiple geographically separate populations. Our physics-inspired mechanistic model could be applied to other bird and highly-mobile species, improving our understanding of the relative importance of various factors driving migration and making predictions that could be useful for conservation.
Full Text Available Cannibalism has been shown to be important to the collective motion of mass migratory bands of insects, such as locusts and Mormon crickets. These mobile groups consist of millions of individuals and are highly destructive to vegetation. Individuals move in response to attacks from approaching conspecifics and bite those ahead, resulting in further movement and encounters with others. Despite the importance of cannibalism, the way in which individuals make attack decisions and how the social context affects these cannibalistic interactions is unknown. This can be understood by examining the decisions made by individuals in response to others. We performed a field investigation which shows that adult Mormon crickets were more likely to approach and attack a stationary cricket that was side-on to the flow than either head- or abdomen-on, suggesting that individuals could reduce their risk of an attack by aligning with neighbours. We found strong social effects on cannibalistic behaviour: encounters lasted longer, were more likely to result in an attack, and attacks were more likely to be successful if other individuals were present around a stationary individual. This local aggregation appears to be driven by positive feedback whereby the presence of individuals attracts others, which can lead to further crowding. This work improves our understanding of the local social dynamics driving migratory band formation, maintenance and movement at the population level.

Full Text Available Recent years have seen a growing consensus that events during one part of an animal's annual cycle can detrimentally affect its future fitness. Notably, migratory species have been shown to commonly display such carry-over effects, facing severe time constraints and physiological stresses that can influence events across seasons. However, to date, no study has examined a full annual cycle to determine when these carry-over effects arise and how long they persist within and across years. Understanding when carry-over effects are created and how they persist is critical to identifying those periods and geographic locations that constrain the annual cycle of a population and determining how selection is acting upon individuals throughout the entire year. Using three consecutive years of migration tracks and four consecutive years of breeding success data, we tested whether carry-over effects in the form of timing deviations during one migratory segment of the annual cycle represent fitness costs that persist or accumulate across the annual cycle for a long-distance migratory bird, the Hudsonian godwit, Limosa haemastica. We found that individual godwits could migrate progressively later than population mean over the course of an entire migration period, especially southbound migration, but that these deviations did not accumulate across the entire year and were not consistently detected among individuals across years. Furthermore, neither the accumulation of lateness during previous portions of the annual cycle nor arrival date at the breeding grounds resulted in individuals suffering reductions in their breeding success or survival. Given their extreme life history, such a lack of carry-over effects suggests that strong selection exists on godwits at each stage of the annual cycle and that carry-over effects may not be able to persist in such a system, but also emphasizes that high-quality stopover and wintering sites are critical to the

Over the past several decades molecular tools have shown an enormous potential to aid in the clarification of species boundaries in the marine realm, particularly in morphologically simple groups. In this paper we report a case of cryptic speciation in an allegedly cosmopolitan and ecologically important species-the excavating sponge Cliona celata (Clionaidae, Hadromerida). In the Northeast Atlantic and Mediterranean C. celata displays a discontinuous distribution of its putative growth stages (boring, encrusting, and massive) leading us to investigate its specific status. Phylogenetic reconstructions of mitochondrial (COI, Atp8) and nuclear (28S) gene fragments revealed levels of genetic diversity and divergence compatible with interspecific relationships. We therefore demonstrate C. celata as constituting a species complex comprised of at least four morphologically indistinct species, each showing a far more restricted distribution: two species on the Atlantic European coasts and two on the Mediterranean and adjacent Atlantic coasts (Macaronesian islands). Our results provide further confirmation that the different morphotypes do indeed constitute either growth stages or ecologically adapted phenotypes as boring and massive forms were found in two of the four uncovered species. We additionally provide an overview of the cases of cryptic speciation which have been reported to date within the Porifera, and highlight how taxonomic crypsis may confound scientific interpretation and hamper biotechnological advancement. Our work together with previous studies suggests that overconservative systematic traditions but also morphological stasis have led to genetic complexity going undetected and that a DNA-assisted taxonomy may play a key role in uncovering the hidden diversity in this taxonomic group.

A survey to obtain potential antagonists of pome fruit tree diseases yielded two yellow epiphytic bacterial isolates morphologically similar to Pantoea agglomerans , but showing no biocontrol activity. Whole-cell MALDI-TOF mass spectrometry and analysis of 16S rRNA gene and gyrB sequences suggested the possibility of a novel species with a phylogenetic position in either the genus Pantoea or the genus Erwinia . Multi-locus sequence analysis (MLSA) placed the two strains in the genus Erwinia and supported their classification as a novel species. The strains showed general phenotypic characteristics typical of this genus and results of DNA-DNA hybridizations confirmed that they represent a single novel species. Both strains showed a DNA G+C content, as determined by HPLC, of 54.5 mol% and could be discriminated from phylogenetically related species of the genus Erwinia by their ability to utilize potassium gluconate, potassium 2-ketogluconate, maltose, melibiose and raffinose. Whole-genome sequencing of strain EM595 T revealed the presence of a chromosomal carotenoid biosynthesis gene cluster similar to those found in species of the genera Cronobacter and Pantoea that explains the pigmentation of the strain, which is atypical for the genus Erwinia . Additional strains belonging to the same species were recovered from different plant hosts in three different continents, revealing the cosmopolitan nature of this epiphyte. The name Erwinia gerundensis sp. nov. is proposed, with EM595 T ( = LMG 28990 T = CCOS 903 T ) as the designated type strain.

Hydrocharitaceae is a fully aquatic monocot family, consists of 18 genera with approximately 120 species. The family includes both fresh and marine aquatics and exhibits great diversity in form and habit including annual and perennial life histories; submersed, partially submersed and floating leaf habits and linear to orbicular leaf shapes. The family has a cosmopolitan distribution and is well represented in the Tertiary fossil record in Europe. At present, the historical biogeography of the family is not well understood and the generic relationships remain controversial. In this study we investigated the phylogeny and biogeography of Hydrocharitaceae by integrating fossils and DNA sequences from eight genes. We also conducted ancestral state reconstruction for three morphological characters. Phylogenetic analyses produced a phylogeny with most branches strongly supported by bootstrap values greater than 95 and Bayesian posterior probability values of 1.0. Stratiotes is the first diverging lineage with the remaining genera in two clades, one clade consists of Lagarosiphon, Ottelia, Blyxa, Apalanthe, Elodea and Egeria; and the other consists of Hydrocharis-Limnobium, Thalassia, Enhalus, Halophila, Najas, Hydrilla, Vallisneria, Nechamandra and Maidenia. Biogeographic analyses (DIVA, Mesquite) and divergence time estimates (BEAST) resolved the most recent common ancestor of Hydrocharitaceae as being in Asia during the Late Cretaceous and Palaeocene (54.7-72.6 Ma). Dispersals (including long-distance dispersal and migrations through Tethys seaway and land bridges) probably played major roles in the intercontinental distribution of this family. Ancestral state reconstruction suggested that in Hydrocharitaceae evolution of dioecy is bidirectional, viz., from dioecy to hermaphroditism, and from hermaphroditism to dioecy, and that the aerial-submerged leaf habit and short-linear leaf shape are the ancestral states. Our study has shed light on the previously controversial
The author examines migration patterns in Southern Europe during the 1970s and early 1980s, noting particularly the reduction in migration northward from this region. It is noted that "departure potential remains sizable in certain areas of Portugal, Spain, Southern Italy, and most particularly, of Turkey and Yugoslavia. Transoceanic migrations have by no means ceased, as new flows of skilled labor have, since 1974, gone towards Arab states endowed with petrol (oil) revenues. And yet, the paramount fact is most surely the emergence and the proliferation in Greece, Spain, and (especially) in Italy, of basically clandestine (illegal) immigration. This movement is due to the convergence of several factors: economic and demographic disparities between northern and southern shores of the Mediterranean Sea, the sealing-off of borders in Northwestern Europe and the 'carry-over' effect upon nations of 'transit', the extent of the flow of refugees, and--most particularly--the appeal provided by the development, in these new employer countries, of an underground economy accompanied by the extension into industry of the practice of 'undeclared' work. And notwithstanding the series of rules lastly drawn up in Spain and in Greece, such forms of clandestine (unauthorized) migration appear highly likely--to say the least--to persist."

Full Text Available The migratory shorebirds of the East Atlantic flyway land in huge numbers during a migratory stopover or wintering on the French Atlantic coast. The Brouage bare mudflat (Marennes-Oléron Bay, NE Atlantic is one of the major stopover sites in France. The particular structure and function of a food web affects the efficiency of carbon transfer. The structure and functioning of the Brouage food web is crucial for the conservation of species landing within this area because it provides sufficient food, which allows shorebirds to reach the north of Europe where they nest. The aim of this study was to describe and understand which food web characteristics support nutritional needs of birds. Two food-web models were constructed, based on in situ measurements that were made in February 2008 (the presence of birds and July 2008 (absence of birds. To complete the models, allometric relationships and additional data from the literature were used. The missing flow values of the food web models were estimated by Monte Carlo Markov Chain--Linear Inverse Modelling. The flow solutions obtained were used to calculate the ecological network analysis indices, which estimate the emergent properties of the functioning of a food-web. The total activities of the Brouage ecosystem in February and July are significantly different. The specialisation of the trophic links within the ecosystem does not appear to differ between the two models. In spite of a large export of carbon from the primary producer and detritus in winter, the higher recycling leads to a similar retention of carbon for the two seasons. It can be concluded that in February, the higher activity of the ecosystem coupled with a higher cycling and a mean internal organization, ensure the sufficient feeding of the migratory shorebirds.

American woodcock (Scolopax minor) are managed as a Central and an Eastern population in the United States and Canada based on band return data showing little crossover between populations or management regions. The observed proportion of crossover between management regions, however, depends on the criteria used to subset the band return data. We analyzed the amount of crossover between management regions using only band return records that represent complete migrations between the breeding and wintering grounds by using only band return records in which the capture took place during the breeding season and the band recovery took place during the wintering season or vice versa (n = 224). Additionally, we applied spatial statistics and a clustering algorithm to investigate woodcock migratory connectivity using this subset of migratory woodcock band return records. Using raw counts, 17.9% of records showed crossover between management regions, a higher proportion than the <5% crossover reported in studies that did not use only migratory band returns. Our results showed woodcock from the breeding grounds in the Central Region largely migrate to destinations within the Central Region, whereas woodcock from the breeding grounds in the Eastern Region migrate to destinations across the entire wintering range and mix with individuals from the Central Region. Using the division coefficient, we estimated that 54% of woodcock from the breeding grounds of the Eastern Region migrate to the Central Region wintering grounds. Our result that many woodcock from separate regions of the breeding grounds mix on the wintering grounds has implications for the 2-region basis for woodcock management. Elucidating finer scale movement patterns among regions provides a basis for reassessing the need for separate management regions to ensure optimal conservation and management of the species.

This paper focuses on a recent gesture by the Spanish novelist and public intellectual Antonio Muñoz Molina to publicly recuperate Aub’s testimony of uprootedness in France, Algeria, and Mexico, a gesture that relies on the concept of cosmopolitan memory as it has been developed in Holocaust studies.

Migratory behaviour is controlled by endogenous circannual rhythms that are synchronized by external cues, such as photoperiod. Investigations on the genetic basis of circannual rhythmicity in vertebrates have highlighted that variation at candidate 'circadian clock' genes may play a major role in regulating photoperiodic responses and timing of life cycle events, such as reproduction and migration. In this comparative study of 23 trans-Saharan migratory bird species, we investigated the relationships between species-level genetic variation at two candidate genes, Clock and Adcyap1, and species' traits related to migration and geographic distribution, including timing of spring migration across the Mediterranean Sea, migration distance and breeding latitude. Consistently with previous evidence showing latitudinal clines in 'circadian clock' genotype frequencies, Clock allele size increased with breeding latitude across species. However, early- and late-migrating species had similar Clock allele size. Species migrating over longer distances, showing delayed spring migration and smaller phenotypic variance in spring migration timing, had significantly reduced Clock (but not Adcyap1) gene diversity. Phylogenetic confirmatory path analysis suggested that migration date and distance were the most important variables directly affecting Clock gene diversity. Hence, our study supports the hypothesis that Clock allele size increases poleward as a consequence of adaptation to the photoperiodic regime of the breeding areas. Moreover, we show that long-distance migration is associated with lower Clock diversity, coherently with strong stabilizing selection acting on timing of life cycle events in long-distance migratory species, likely resulting from the time constraints imposed by late spring migration. © 2016 John Wiley & Sons Ltd.

However, few studies have investigated whether variation in body......

Full Text Available Abstract Background Hydrocharitaceae is a fully aquatic monocot family, consists of 18 genera with approximately 120 species. The family includes both fresh and marine aquatics and exhibits great diversity in form and habit including annual and perennial life histories; submersed, partially submersed and floating leaf habits and linear to orbicular leaf shapes. The family has a cosmopolitan distribution and is well represented in the Tertiary fossil record in Europe. At present, the historical biogeography of the family is not well understood and the generic relationships remain controversial. In this study we investigated the phylogeny and biogeography of Hydrocharitaceae by integrating fossils and DNA sequences from eight genes. We also conducted ancestral state reconstruction for three morphological characters. Results Phylogenetic analyses produced a phylogeny with most branches strongly supported by bootstrap values greater than 95 and Bayesian posterior probability values of 1.0. Stratiotes is the first diverging lineage with the remaining genera in two clades, one clade consists of Lagarosiphon, Ottelia, Blyxa, Apalanthe, Elodea and Egeria; and the other consists of Hydrocharis-Limnobium, Thalassia, Enhalus, Halophila, Najas, Hydrilla, Vallisneria, Nechamandra and Maidenia.

Identifying movement routes and stopover sites is necessary for developing effective management and conservation strategies for migratory animals. In the case of migratory birds, a collection of migration routes, known as a flyway, is often hundreds to thousands of kilometers long and can extend across political boundaries. Flyways encompass the entire geographic range between the breeding and non-breeding areas of a population, species, or a group of species, and they provide spatial frameworks for management and conservation across international borders. Existing flyway maps are largely qualitative accounts based on band returns and survey data rather than observed movement routes. In this study, we use satellite and GPS telemetry data and dynamic Brownian bridge movement models to build upon existing maps and describe waterfowl space use probabilistically in the Central Asian and East Asian-Australasian Flyways. Our approach provided new information on migratory routes that was not easily attainable with existing methods to describe flyways. Utilization distributions from dynamic Brownian bridge movement models identified key staging and stopover sites, migration corridors and general flyway outlines in the Central Asian and East Asian-Australasian Flyways. A map of space use from ruddy shelducks depicted two separate movement corridors within the Central Asian Flyway, likely representing two distinct populations that show relatively strong connectivity between breeding and wintering areas. Bar-headed geese marked at seven locations in the Central Asian Flyway showed heaviest use at several stopover sites in the same general region of high-elevation lakes along the eastern Qinghai-Tibetan Plateau. Our analysis of data from multiple Anatidae species marked at sites throughout Asia highlighted major movement corridors across species and confirmed that the Central Asian and East Asian-Australasian Flyways were spatially distinct.

Full Text Available This article discusses the form of social capital present among Malaysian Chinese youth, comparing across those who are Chinese-medium educated and English-medium educated. The reason for comparison is because of the dichotomy of Confucian values in Chinese-medium education and Western liberal democratic values in English-medium education, which may influence their choice of social network. Using a self-designed survey questionnaire, I assessed whether Putnam’s two forms of social capital, the bridging and the bonding social capital, are found in these two sub-ethnic groups. In terms of face-to-face interaction, it is found that ethnic identification remains a strong influence on respondents’ choice of social network. However, respondents also demonstrate an aspiration to network on a more global scale if facilitated by information communication technology. Given Malaysia’s present globalised environment, with strong migratory flows inside and outside, the reality of respondents’ social capital does not match the expectations respondents have of themselves. While they express a desire to network in a global nexus, in order to be more connected to the rest of the world, they are still restrained by attributes like ethnic identification and language preference.

The US Department of Energy and US Department of the Interior, Bureau of Ocean Energy Management commissioned this study to address the limited scientific data on the impacts of high voltage direct current cables on aquatic biota, in particular migratory species within the San Francisco Bay. Empirical evidence exists that marine animals perceive and orient to local distortions in the earth’s main geomagnetic field magnetic field. The electromagnetic fields (EMF) generated by the cables that carry electricity from hydrokinetic energy sources to shore-based power stations may produce similar local distortions in the earth’s main field. Concern exists that animals that migrate along the continental shelves might orient to the EMF from the cables, and move either inshore or offshore away from their normal path. The Trans Bay Cable (TBC) is a ±200-kilovolt (kV), 400 MW 85-km long High Voltage Direct Current (DC) buried transmission line linking Pittsburg, CA with San Francisco, CA (SF) through the San Francisco Bay. The study addresses the following specific questions based on measurements and projections of the EMF produced by an existing marine cable, the TBC, in San Francisco Bay. Specifically, does the presence of EMF from an operating power cable alter the behavior and path of bony fishes and sharks along a migratory corridor? Does the EMF from an operating power cable guide migratory movements or pose an obstacle to movement? To meet the main study objectives several activities needed to be carried out: 1) modeling of the magnetic fields produced by the TBC, 2) assessing the migratory impacts on Chinook salmon smolts (Oncorhynchus tshawytscha) and green sturgeon (Acipenser medirostris) as a result of local magnetic field distortions produced by bridge structures and 3) analyzing behavioral responses by migratory Chinook salmon and green sturgeon to a high-voltage power cable. To meet the first objective, magnetic field measurements were made using two

1. One way in which dams affect ecosystem function is by altering the distribution and abundance of aquatic species. 2. Previous studies indicate that migratory shrimps have significant effects on ecosystem processes in Puerto Rican streams, but are vulnerable to impediments to upstream or downstream passage, such as dams and associated water intakes where stream water is withdrawn for human water supplies. Ecological effects of dams and water withdrawals from streams depend on spatial context and temporal variability of flow in relation to the amount of water withdrawn. 3. This paper presents a conceptual model for estimating the probability that an individual shrimp is able to migrate from a stream's headwaters to the estuary as a larva, and then return to the headwaters as a juvenile, given a set of dams and water withdrawals in the stream network. The model is applied to flow and withdrawal data for a set of dams and water withdrawals in the Caribbean National Forest (CNF) in Puerto Rico. 4. The index of longitudinal riverine connectivity (ILRC), is used to classify 17 water intakes in streams draining the CNF as having low, moderate, or high connectivity in terms of shrimp migration in both directions. An in-depth comparison of two streams showed that the stream characterized by higher water withdrawal had low connectivity, even during wet periods. Severity of effects is illustrated by a drought year, where the most downstream intake caused 100% larval shrimp mortality 78% of the year. 5. The ranking system provided by the index can be used as a tool for conservation ecologists and water resource managers to evaluate the relative vulnerability of migratory biota in streams, across different scales (reach-network), to seasonally low flows and extended drought. This information can be used to help evaluate the environmental tradeoffs of future water withdrawals. ?? 2008 John Wiley & Sons, Ltd.

Lateralization of brain functions, once believed to be a human characteristic, has now been found to be widespread among vertebrates. In birds, asymmetries of visual functions are well studied, with each hemisphere being specialized for different tasks. Here we report lateralized functions of the birds' visual system associated with magnetoperception, resulting in an extreme asymmetry of sensing the direction of the magnetic field. We found that captive migrants tested in cages with the magnetic field as the only available orientation cue were well oriented in their appropriate migratory direction when using their right eye only, but failed to show a significant directional preference when using their left eye. This implies that magnetoreception for compass orientation, assumed to take place in the eyes alongside the visual processes, is strongly lateralized, with a marked dominance of the right eye/left brain hemisphere.

White-throated sparrows increase fat deposits during pre-migratory periods and rely on these fat stores to fuel migration. Adipose tissue produces hormones and signaling factors in a rhythmic fashion and may be controlled by a clock in adipose tissue or driven by a master clock in the brain. The master clock may convey photoperiodic information from the environment to adipose tissue to facilitate pre-migratory fattening, and adipose tissue may, in turn, release adipokines to indicate the extent of fat energy stores. Here, we present evidence that a change in signal from the adipokines adiponectin and visfatin may act to indicate body condition, thereby influencing an individual's decision to commence migratory flight, or to delay until adequate fat stores are acquired. We quantified plasma adiponectin and visfatin levels across the day in captive birds held under constant photoperiod. The circadian profiles of plasma adiponectin in non-migrating birds were approximately inverse the profiles from migrating birds. Adiponectin levels were positively correlated to body fat, and body fat was inversely related to the appearance of nocturnal migratory restlessness. Visfatin levels were constant across the day and did not correlate with fat deposits; however, a reduction in plasma visfatin concentration occurred during the migratory period. The data suggest that a significant change in the biological control of adipokine expression exists between the two migratory conditions and we propose a role for adiponectin, visfatin and adipose clocks in the regulation of migratory behaviors.

For many marine species, locations of migratory pathways are not well defined. We used satellite telemetry and switching state-space modeling (SSM) to define the migratory corridor used by Kemp's ridley turtles (Lepidochelys kempii) in the Gulf of Mexico. The turtles were tagged after nesting at Padre Island National Seashore, Texas, USA from 1997 to 2014 (PAIS; n = 80); Rancho Nuevo, Tamaulipas, Mexico from 2010 to 2011 (RN; n = 14); Tecolutla, Veracruz, Mexico from 2012 to 2013 (VC; n = 13); and Gulf Shores, Alabama, USA during 2012 (GS; n = 1). The migratory corridor lies in nearshore Gulf of Mexico waters in the USA and Mexico with mean water depth of 26 m and a mean distance of 20 km from the nearest mainland coast. Migration from the nesting beach is a short phenomenon that occurs from late-May through August, with a peak in June. There was spatial similarity of post-nesting migratory pathways for different turtles over a 16 year period. Thus, our results indicate that these nearshore Gulf waters represent a critical migratory habitat for this species. However, there is a gap in our understanding of the migratory pathways used by this and other species to return from foraging grounds to nesting beaches. Therefore, our results highlight the need for tracking reproductive individuals from foraging grounds to nesting beaches. Continued tracking of adult females from PAIS, RN, and VC nesting beaches will allow further study of environmental and bathymetric components of migratory habitat and threats occurring within our defined corridor. Furthermore, the existence of this migratory corridor in nearshore waters of both the USA and Mexico demonstrates that international cooperation is necessary to protect essential migratory habitat for this imperiled species.

Migratory birds face many changes to the landscapes they traverse and the habitats they use. Wind turbines and communications towers, which pose hazards to birds and bats in flight, are being erected or proposed across the United States and offshore. Human activities can also destroy or threaten habitats critical to birds during migratory passage, and climate change appears to be altering migratory patterns. The U.S. Fish and Wildlife Service (USFWS) and other agencies are under increasing pressure to identify and evaluate movement patterns and habitats used during migration and other times.

The paternal origins of Thoroughbred racehorses trace back to a handful of Middle Eastern stallions, imported to the British Isles during the seventeenth century. Yet, few details of the foundation mares were recorded, in many cases not even their names (several different maternal lineages trace back to 'A Royal Mare'). This has fuelled intense speculation over their origins. We examined mitochondrial DNA from 1929 horses to determine the origin of Thoroughbred foundation mares. There is no evidence to support exclusive Arab maternal origins as some historical records have suggested, or a significant importation of Oriental mares (the term used in historic records to refer to Middle East and western Asian breeds including Arab, Akhal-Teke, Barb and Caspian). Instead, we show that Thoroughbred foundation mares had a cosmopolitan European heritage with a far greater contribution from British and Irish Native mares than previously recognized.

Full Text Available In facultative partial migrants some individuals in a population are migratory and others are resident and individuals decide each year anew which strategy to choose.

Furthermore, lean birds started to explore earlier than birds with larger fat reserves again indicating an effect of maintaining threshold energy reserves. Moreover, late migrating juveniles, started to explore earlier than early migrating juveniles possibly due to time constraints to find high-quality foraging patches or a suitable winter home. Finally, neophobia did not change over the migratory season indicating that this behaviour is not compromised by time constraints. The results overall indicate that decisions on route are mainly governed by energetic requirements and current needs to learn about the environment and only to a small extent by differences in personality.

Public agencies sometimes seek outside guidance when capacity to achieve their mission is limited. Through a cooperative agreement and collaborations with the U.S. National Park Service (NPS), we developed recommendations for a conservation program for migratory species. Although NPS manages ∼ 36 million hectares of land and water in 401 units, there is no centralized program to conserve wild animals reliant on NPS units that also migrate hundreds to thousands of kilometers beyond parks. Migrations are imperiled by habitat destruction, unsustainable harvest, climate change, and other impediments. A successful program to counter these challenges requires public support, national and international outreach, and flourishing migrant populations. We recommended two initial steps. First, in the short term, launch or build on a suite of projects for high-profile migratory species that can serve as proof to demonstrate the centrality of NPS units to conservation at different scales. Second, over the longer term, build new capacity to conserve migratory species. Capacity building will entail increasing the limited knowledge among park staff about how and where species or populations migrate, conditions that enable migration, and identifying species' needs and resolving them both within and beyond parks. Building capacity will also require ensuring that park superintendents and staff at all levels support conservation beyond statutory borders. Until additional diverse stakeholders and a broader American public realize what can be lost and do more to protect it and engage more with land management agencies to implement actions that facilitate conservation, long distance migrations are increasingly likely to become phenomena of the past. © 2014 Society for Conservation Biology.

The results overall indicate that decisions on route are mainly governed by energetic requirements and current needs to learn about the environment and only to a small extent by differences in personality.

Full Text Available The current context of globalisation is often characterised by its transformative effects on traditional definitions of place and culture, especially in relation to the concept of the nation state and its role in structuring modern understandings of individual and collective belonging. In opposition to a bounded, reactionary notion of place, associated with a given, self-contained, local cultural community, human geographers have proposed a progressive “global sense of place” (Massey 1991, characterised by its unboundedness, and understood as “the location of the intersections of particular bundles of activity spaces, of connections and interrelations, of influences and movements” that link it to the wider world (Massey 1995: 59. This relational global sense of place informs sociologist Ulrich Beck’s conceptualisation of place from a cosmopolitan perspective, according to which national societies are transformed by a process of “internal cosmopolitanisation” (2004: 9 in which place becomes “the locus of encounters and interminglings or, alternatively, of anonymous coexistence and the overlapping of possible worlds and global dangers” (2004: 10. In this sense, the main aim of this paper is to analyse how British Indian writer Hari Kunzru’s Gods Without Men (2011 subverts, both thematically and in terms of narrative structure, a bounded notion of place from a “cosmopolitan outlook” (Beck 2004: 2. It is my contention that in the novel the location of the Pinnacles in the Mojave Desert, California, acts as a symbolic locus where the different stories that compose the narrative whole crisscross to outline a new topography of collective belonging. By historicising and re-examining from a current transnational viewpoint traditional understandings of the sense of place, with special attention to the inextricably interrelated concept of spirituality, Kunzru provides a cosmopolitanised narrative of America, which underscores the
Full Text Available Background The most traditional scheme for migration among baleen whales comprises yearly migrations between productive waters at high latitude summer feeding grounds and warmer waters at lower latitudes where whales calve and mate, but rarely feed. Evidence indicates, however, that large departures from this scheme exist among populations and individuals. Furthermore, for some populations there is virtually no information on migratory pathways and destinations. Such is the case of Chilean blue whales throughout the Eastern South Pacific; hence, the goal of this study was to assess its migratory behavior. Methods Dedicated marine surveys and satellite tagging efforts were undertaken during the austral summer and early autumn on blue whale feeding grounds off Chilean Northern Patagonia (CNP during 2013, 2015 and 2016. Positional data derived from satellite tags regarding movement patterns and behavior were analyzed using Bayesian switching first-difference correlated random walk models. Results We instrumented 10 CNP blue whales with satellite transmitters and documented individual variation in departure time, northbound migratory routes and potential wintering grounds. The onset of migration occurred from mid/late austral autumn to well into the austral winter. Blue whales moved in various directions, but ultimately converged toward a general NW movement direction along a wide corridor exceeding 2,000 km. Area-Restricted Search behavior was exhibited within fjords and channels of CNP and also South of Galapagos Archipelago (GA and northern Peru, but never during migration. Interestingly, dive profiles for one whale that reached GA showed a sharp and consistent increase in depth north of 5°S and extreme deep dives of up to 330 m. Discussion Information derived from satellite tagged blue whales in this study is the first of its kind off the Eastern Southern Pacific. Our results provide valuable information on their migratory timing, routes and
Full Text Available This paper focuses on using data mining technology to efficiently and accurately discover habitats and stopovers of migratory birds. The three methods we used are as follows: 1. a density-based clustering method, detecting stopovers of birds during their migration through density-based clustering of location points; 2. A location histories parser method, detecting areas that have been overstayed by migratory birds during a set time period by setting time and distance thresholds; and 3. A time-parameterized line segment clustering method, clustering directed line segments to analyze shared segments of migratory pathways of different migratory birds and discover the habitats and stopovers of these birds. Finally, we analyzed the migration data of the bar-headed goose in the Qinghai Lake Area through the three above methods and verified the effectiveness of the three methods and, by comparison, identified the scope and context of the use of these three methods respectively.

Full Text Available It is increasingly acknowledged that migratory birds, notably waterfowl, play a critical role in the maintenance and spread of influenza A viruses. In order to elucidate the epidemiology of influenza A viruses in their natural hosts, a better understanding of the pathological effects in these hosts is required. Here we report on the feeding and migratory performance of wild migratory Bewick's swans (Cygnus columbianus bewickii Yarrell naturally infected with low-pathogenic avian influenza (LPAI A viruses of subtypes H6N2 and H6N8. Using information on geolocation data collected from Global Positioning Systems fitted to neck-collars, we show that infected swans experienced delayed migration, leaving their wintering site more than a month after uninfected animals. This was correlated with infected birds travelling shorter distances and fuelling and feeding at reduced rates. The data suggest that LPAI virus infections in wild migratory birds may have higher clinical and ecological impacts than previously recognised.

Strategic plans to conserve migratory species require detailed knowledge on species distribution, abundance, and habitat use over the annual cycle, but such data are lacking for most species. We developed a hemispheric approach to planning using spatiotemporally explicit species abundance models to prioritize land needed to conserve ≥17% of the global populations of 109 species of Neotropical migratory birds. The efficiency of annual cycle plans was evaluated in comparisons to single-season p...

Edwards Air Force Base (AFB) scheduled the construction of a runway in the spring of 2007. The runway would be in an area that contained migratory birds and their habitat. The construction project would be near Edwards AFB main runway and had the potential not only to impact species protected under the Migratory Bird Treaty Act (MBTA), including the burrowing owl (Athene cunicularia), but also to increase bird and wildlife–aircraft strike hazards in the active flightline areas. To discourage ...

Understanding the biology and conducting effective conservation of migratory species requires an understanding of migratory connectivity – the geographic linkages of populations between stages of the annual cycle. Unfortunately, for most species, we are lacking such information. The North American Bird Banding Laboratory (BBL) houses an extensive database of marking, recaptures and recoveries, and such data could provide migratory connectivity information for many species. To date, however, few species have been analyzed for migratory connectivity largely because heterogeneous re-encounter probabilities make interpretation problematic. We accounted for regional variation in re-encounter probabilities by borrowing information across species and by using effort covariates on recapture and recovery probabilities in a multistate capture–recapture and recovery model. The effort covariates were derived from recaptures and recoveries of species within the same regions. We estimated the migratory connectivity for three tern species breeding in North America and over-wintering in the tropics, common (Sterna hirundo), roseate (Sterna dougallii), and Caspian terns (Hydroprogne caspia). For western breeding terns, model-derived estimates of migratory connectivity differed considerably from those derived directly from the proportions of re-encounters. Conversely, for eastern breeding terns, estimates were merely refined by the inclusion of re-encounter probabilities. In general, eastern breeding terns were strongly connected to eastern South America, and western breeding terns were strongly linked to the more western parts of the nonbreeding range under both models. Through simulation, we found this approach is likely useful for many species in the BBL database, although precision improved with higher re-encounter probabilities and stronger migratory connectivity. We describe an approach to deal with the inherent biases in BBL banding and re-encounter data to demonstrate

A comprehensive climatology of migratory anticyclones affecting the Mediterranean was generated with the aid of the University of Melbourne finding and tracking algorithm, applied to 34 years (1979-2012) of ERA-Interim mean sea level pressures. The algorithm is employed for the first time to study anticyclones in this region, thus, its robustness and reliability in efficiently capturing the individual characteristics of the anticyclonic tracks in the Mediterranean were checked and verified. The tracks and the statistical properties of the migratory systems revealed two major anticyclonic routes: over the northern (i.e. from the Iberian towards the Balkan Peninsula) and over the southern (i.e. the North Africa coast) Mediterranean barriers. A transition of the system density and anticyclogenesis maxima is evident throughout the year from solely continental environments in winter and autumn to also maritime in spring and summer. These variations can be attributed to the seasonal variability of the major anticyclonic systems that are involved in this region. The interannual variability of synoptic systems can be attributed to natural low frequency variability. The interannual variations of the system density and strength were linked to the Northern Hemisphere modes of atmospheric variability; e.g. more (less) antiyclonic tracks are observed around the Mediterranean basin during periods of positive (negative) NAO, with a consequent enhancement (decline) of the pressure field. Moreover, possible trends in the frequency and intensity of the anticyclonic systems were explored in an attempt to examine any impacts of recent global warming conditions. Positive trends of system density, genesis and intensity prevail during the cold period over the greater area around the Mediterranean basin. During summer, the general increase in system density is not followed by a corresponding tendency in the number of the generating systems and the intensity. Regarding the depth of the

Parasitism is not well documented for birds found in tropical habitats. Long-distance migratory birds may face additional risks to an already hazardous journey when infected. This study explores the ecology of an ectoparasite infestation in Chiapas, Mexico. During a mist-netting project in 2 different coffee management systems, chigger mites (Acarina: Trombiculidae), ectoparasitic during the larval stage, were found on both resident and migratory birds. Using a rapid assessment protocol, it was observed that 17 of 26 species of long-distance migrants and 33 of 71 resident species had at least 1 infested individual. Infestation prevalences were unexpectedly high on some long-distance migrants, as high as 0.73 for Swainson's thrush (Catharus ustulatus), a value on par with heavily infested resident species. Prevalence was highest during winter sampling: 0.18 overall, 0.16 of migrants, and 0.23 of residents. Prevalence was 0.14 for resident birds during the summer breeding season. Mean abundance and mean intensity of infestation are reported for 97 species captured and inspected during the course of this study. In this region, chigger mite larvae are relatively common on birds and their abundance varies seasonally. High prevalence for some migratory birds suggests that more research and monitoring of ectoparasites are needed, especially in light of emerging diseases.

Migratory species support ecosystem process and function in multiple areas, establishing ecological linkages between their different habitats. As they travel, migratory species also provide ecosystem services to people in many different locations. Previous research suggests there may be spatial mismatches between locations where humans use services and the ecosystems that produce them. This occurs with migratory species, between the areas that most support the species' population viability – and hence their long-term ability to provide services – and the locations where species provide the most ecosystem services. This paper presents a conceptual framework for estimating how much a particular location supports the provision of ecosystem services in other locations, and for estimating the extent to which local benefits are dependent upon other locations. We also describe a method for estimating the net payment, or subsidy, owed by or to a location that balances benefits received and support provided by locations throughout the migratory range of multiple species. The ability to quantify these spatial subsidies could provide a foundation for the establishment of markets that incentivize cross-jurisdictional cooperative management of migratory species. It could also provide a mechanism for resolving conflicts over the sustainable and equitable allocation of exploited migratory species.

Unprecedented numbers of migratory bats are found dead beneath industrial-scale wind turbines during late summer and autumn in both North America and Europe. Prior to the wide-scale deployment of wind turbines, fatal collisions of migratory bats with anthropogenic structures were rarely reported and likely occurred very infrequently. There are no other well-documented threats to populations of migratory tree bats that cause mortality of similar magnitude to that observed at wind turbines. Just three migratory species comprise the vast majority of bat kills at turbines in North America and there are indications that turbines may actually attract migrating individuals toward their blades. Although fatality of certain migratory species is consistent in occurrence across large geographic regions, fatality rates differ across sites for reasons mostly unknown. Cumulative fatality for turbines in North America might already range into the hundreds of thousands of bats per year. Research into the causes of bat fatalities at wind turbines can ascertain the scale of the problem and help identify solutions. None of the migratory bats known to be most affected by wind turbines are protected by conservation laws, nor is there a legal mandate driving research into the problem or implementation of potential solutions.

Understanding the evolutionary history of contemporary animal groups is essential for conservation and management of endangered species like caribou (Rangifer tarandus). In central Canada, the ranges of two caribou subspecies (barren-ground/woodland caribou) and two woodland caribou ecotypes (boreal/eastern migratory) overlap. Our objectives were to reconstruct the evolutionary history of the eastern migratory ecotype and to assess the potential role of introgression in ecotype evolution. STRUCTURE analyses identified five higher order groups (i.e. three boreal caribou populations, eastern migratory ecotype and barren-ground). The evolutionary history of the eastern migratory ecotype was best explained by an early genetic introgression from barren-ground into a woodland caribou lineage during the Late Pleistocene and subsequent divergence of the eastern migratory ecotype during the Holocene. These results are consistent with the retreat of the Laurentide ice sheet and the colonization of the Hudson Bay coastal areas subsequent to the establishment of forest tundra vegetation approximately 7000 years ago. This historical reconstruction of the eastern migratory ecotype further supports its current classification as a conservation unit, specifically a Designatable Unit, under Canada's Species at Risk Act. These findings have implications for other sub-specific contact zones for caribou and other North American species in conservation unit delineation.
Full Text Available Abstract Background Infection with H5N1 highly pathogenic avian influenza viruses (HPAIVs of domestic poultry and wild birds has spread to more than 60 countries in Eurasia and Africa. It is concerned that HPAIVs may be perpetuated in the lakes in Siberia where migratory water birds nest in summer. To monitor whether HPAIVs circulate in migratory water birds, intensive surveillance of avian influenza has been performed in Mongolia and Japan in autumn each year. Until 2008, there had not been any H5N1 viruses isolated from migratory water birds that flew from their nesting lakes in Siberia. In autumn 2009, A/mallard/Hokkaido/24/09 (H5N1 (Mal/Hok/24/09 was isolated from a fecal sample of a mallard (Anas platyrhynchos that flew from Siberia to Hokkaido, Japan. The isolate was assessed for pathogenicity in chickens, domestic ducks, and quails and analyzed antigenically and phylogenetically. Results No clinical signs were observed in chickens inoculated intravenously with Mal/Hok/24/09 (H5N1. There was no viral replication in chickens inoculated intranasally with the isolate. None of the domestic ducks and quails inoculated intranasally with the isolate showed any clinical signs. There were no multiple basic amino acid residues at the cleavage site of the hemagglutinin (HA of the isolate. Each gene of Mal/Hok/24/09 (H5N1 is phylogenetically closely related to that of influenza viruses isolated from migratory water birds that flew from their nesting lakes in autumn. Additionally, the antigenicity of the HA of the isolate was similar to that of the viruses isolated from migratory water birds in Hokkaido that flew from their northern territory in autumn and different from those of HPAIVs isolated from birds found dead in China, Mongolia, and Japan on the way back to their northern territory in spring. Conclusion Mal/Hok/24/09 (H5N1 is a non-pathogenic avian influenza virus for chickens, domestic ducks, and quails, and is antigenically and genetically

Full Text Available The semipalmated sandpiper Calidris pusilla and the spotted sandpiper Actitis macularia are long- and short-distance migrants, respectively. C. pusilla breeds in the sub-arctic and mid-arctic tundra of Canada and Alaska and winters on the north and east coasts of South America. A. macularia breeds in a broad distribution across most of North America from the treeline to the southern United States. It winters in the southern United States, and Central and South America. The autumn migration route of C. pusilla includes a non-stop flight over the Atlantic Ocean, whereas autumn route of A. macularia is largely over land. Because of this difference in their migratory paths and the visuo-spatial recognition tasks involved, we hypothesized that hippocampal volume and neuronal and glial numbers would differ between these two species. A. macularia did not differ from C. pusilla in the total number of hippocampal neurons, but the species had a larger hippocampal formation and more hippocampal microglia. It remains to be investigated whether these differences indicate interspecies differences or neural specializations associated with different strategies of orientation and navigation.
Full Text Available Sarconema eurycerca is a common parasitic disease of North America swans and geese. The infection has been correlated with severe heart lesions, often resulting in cardiac failure and death of the animals. Heartworms infections have been previously reported in European swans, and specifically in the United Kingdom and Nederland. Both the countries are characterized by a cold temperate weather, similar to the one that can be found in swan wintering areas of U.S.A. and Canada. The first record of cardiac filariasis associated with Sarconema eurycerca infection in four swans in Italy. Twelve mute swans were examined during avian influenza surveillance activities on migratory birds. Birds were collected in the year 2006, in wintering areas of Eastern Sicily (Italy. Four of the twelve swans showed necrotic-haemorrhagic myocarditis with intra-lesional nematodes. Morphological characteristics identified the parasite as a filarial nematode. Birds lungs samples were used for parasites DNA extraction. The latter was used as template for polymerase chain reaction (PCR amplification and sequencing of part of the 12S rDNA gene. Comparison of genomic DNA extracted from a reference S. eurycerca isolate confirmed parasite identity and provided the first sequence resources for this species of value to future diagnostic and epidemiological studies.
Full Text Available We present a mathematical model that studies and simulates the interconnection between energetic and ecological aspects of bird migration. By comparing model predictions with experimental data, we show that it can be used to assess the impact of changing environmental conditions in breeding, wintering, and stop-over sites on migratory success. We relate in particular to the European white stork (Ciconia ciconia and its Eastern migration route and discuss questions concerning the timing, stopover, and feeding behavior en route. Opinions concerning the importance of resource availability and resource quality en route are divided. Whereas some studies have shown that storks gain weight in the wintering site, but almost do not feed en route, others stress the importance of the quality of stop-over locations. We address these questions and simulate the development of stork populations for changing environmental conditions. We demonstrate that resource availability and competition for breeding sites are crucial factors determining the timing of spring migration and the length of stop-over periods. Analyzing the robustness of migration strategies with respect to changing environmental conditions, we show that birds will shorten their stay in stop-over places of poor resource availability rather than prolonging it in the attempt to gain time for accumulating fat reserves.

In this study were presented the clinical and laboratory findings of eight patients with migratory pneumonia, who were hospitalised in our clinic. It is about eight women with average age of 58±13 years with fever, weakness, dry cough, shortness of breath and who already had received antibiotics. Crackles were the most frequent evidence by the auscultation. All patients showed consolidation in chest radiography which resolved completely from the initial area and migrated in different areas. The chest HRCT showed opacity with air bronchogram and ground glass in places. Regarding to the respiratory function, patients showed mild restriction disorder (average values ± SD: FEV1% 83±24, FVC% 86±21, TLC% 82±16, DLco% 74±15). The average price of pO2 was 68+7 mmHg. The findings of BAL were: macrophages 51%±20%, lymphocytes 33.5%±14%, neutrophils 7.5%±3%, eosinophils 7%±8%. From diagnosis, we excluded eosinophilic pneumonia, infectious causes, collagen diseases and vasculitis. The findings of physical examination, chest radiography and the results of the BAL of all of the patients argued for Bronchiolitis obliterans organizing pneumonia (BOOP), the cause of which was not found (cryptogenic organizing pneumonia-COP). All patients responded directly to corticosteroids.

Flight direction is a major component of an animal's migratory success. However, few studies have focused on variation in flight direction both between and within individuals, which is likely to be correlated with other traits implied in migration processes. We report patterns of intra- and inter-individual variation in flight direction in the large white butterfly Pieris brassicae. The presence of inter-individual variation in flight direction for individuals tested in the same conditions suggests that this trait is inherited in P. brassicae and we propose that a rapid loss of migratory skills may exist in the absence of selection for migration. The magnitude of intra-individual variation was negatively correlated to two surrogates of the potential for migration: mobility and wing length. Highly mobile and longed-winged individuals within the same family were found to fly in similar directions, whereas less mobile and short-winged individuals displayed divergent flight direction compared with the average direction of their kin. There was also a negative correlation between the variance to the mean flight direction of a family and its average mobility, but no correlation with wing length. We discuss these issues in terms of the evolution of traits potentially implied in both migration and dispersal in P. brassicae.

Long-distance migration can lower infection risk for animal populations by removing infected individuals during strenuous journeys, spatially separating susceptible age classes, or allowing migrants to periodically escape from contaminated habitats. Many seasonal migrations are changing due to human activities including climate change and habitat alteration. Moreover, for some migratory populations, sedentary behaviors are becoming more common as migrants abandon or shorten their journeys in response to supplemental feeding or warming temperatures. Exploring the consequences of reduced movement for host-parasite interactions is needed to predict future responses of animal pathogens to anthropogenic change. Monarch butterflies (Danaus plexippus) and their specialist protozoan parasite Ophryocystis elektroscirrha (OE) provide a model system for examining how long-distance migration affects infectious disease processes in a rapidly changing world. Annual monarch migration from eastern North America to Mexico is known to reduce protozoan infection prevalence, and more recent work suggests that monarchs that forego migration to breed year-round on non-native milkweeds in the southeastern and south central Unites States face extremely high risk of infection. Here, we examined the prevalence of OE infection from 2013 to 2016 in western North America, and compared monarchs exhibiting migratory behavior (overwintering annually along the California coast) with those that exhibit year-round breeding. Data from field collections and a joint citizen science program of Monarch Health and Monarch Alert showed that infection frequency was over nine times higher for monarchs sampled in gardens with year-round milkweed as compared to migratory monarchs sampled at overwintering sites. Results here underscore the importance of animal migrations for lowering infection risk and motivate future studies of pathogen transmission in migratory species affected by environmental change. © The

Improved maps of species distributions are important for effective management of wildlife under increasing anthropogenic pressures. Recent advances in lidar and radar remote sensing have shown considerable potential for mapping forest structure and habitat characteristics across landscapes. However, their relative efficacies and integrated use in habitat mapping remain largely unexplored. We evaluated the use of lidar, radar and multispectral remote sensing data in predicting multi-year bird detections or prevalence for 8 migratory songbird species in the unfragmented temperate deciduous forests of New Hampshire, USA. A set of 104 predictor variables describing vegetation vertical structure and variability from lidar, phenology from multispectral data and backscatter properties from radar data were derived. We tested the accuracies of these variables in predicting prevalence using Random Forests regression models. All data sets showed more than 30% predictive power with radar models having the lowest and multi-sensor synergy ("fusion") models having highest accuracies. Fusion explained between 54% and 75% variance in prevalence for all the birds considered. Stem density from discrete return lidar and phenology from multispectral data were among the best predictors. Further analysis revealed different relationships between the remote sensing metrics and bird prevalence. Spatial maps of prevalence were consistent with known habitat preferences for the bird species. Our results highlight the potential of integrating multiple remote sensing data sets using machine-learning methods to improve habitat mapping. Multi-dimensional habitat structure maps such as those generated from this study can significantly advance forest management and ecological research by facilitating fine-scale studies at both stand and landscape level.

Arctic regions are warming rapidly, with extreme weather events increasing in frequency, duration and intensity, as in other regions. Many studies have focused on how shifting seasonality in environmental conditions affect the phenology and productivity of vegetation, while far fewer have examined how arctic fauna responds. We studied two species of long-distance migratory songbirds, Lapland longspurs, Calcarius lapponicus, and White-crowned sparrows, Zonotrichia leucophrys gambelii, across seven consecutive breeding seasons in northern Alaskan tundra. We aimed to understand how spring environmental conditions affected breeding cycle phenology, food availability, body condition, stress physiology, and ultimately, reproductive success. Spring temperatures, precipitation, storm frequency, and snow-free dates differed significantly among years, with 2013 characterized by unusually late snow cover, and 2015 and 2016 characterized by unusually early snow-free dates and several late spring snowstorms. In response, we found that relative to other study years, there was a significant delay in breeding cycle phenology for both study species in 2013, while breeding cycle phenology was significantly earlier in 2015 only. For both species, we also found significant variation among years in: the seasonal patterns of arthropod availability during the nesting stage; body condition, and; stress physiology. Finally, we found significant variation in reproductive success of both species across years, and that daily survival rates were decreased by snow storm events. Our findings suggest that arctic-breeding passerine communities may be able to adjust phenology to unpredictable shifts in the timing of spring, but extreme conditions during the incubation and nestling stages are detrimental to reproductive success.

The recent turn to a transnational American literary cosmopolitanism, coupled with efforts to move beyond what Paul Gilroy calls “ethnic absolutes,” have generated a resurgence of interest in W. E. B. Du Bois’s 1928 romance novel, Dark Princess. In addition, the last two decades have witnessed tentative movements to bridge the gap between American ethnic studies and postcolonial studies. This essay begins with the premise that there are compelling reasons to reread Dark Princess in light of twenty-first century debates about postcolonialism and cosmopolitanism, but it also points to some of the hazards of reading the novel outside of the social and aesthetic politics of the decades between the two world wars. The main part of this paper is an attempt to address the gendered and sexualized body politics of Du Bois’s aesthetic practices through an analysis of his essay “Criteria of Negro Art” and his novel Dark Princess. Allusions in the novel to the fourth-century BCE Indian political philosopher Kautilya and his treatise Arthasâstra suggests that Du Bois’s naming of his princess, Kautilya, was neither accidental nor insignificant. This trans/gendering of Kautilya speaks to a gender and sexual politics inherent to German theories of the aesthetic, to which Du Bois remained wedded. Scholarly fantasies of cosmopolitanism tend to ignore the extent to which such fantasies depend upon ideologies of family and the reproductive bodies of women.

Very little research into genetic diversity of Italian native dog breeds has been carried out so far. In this study we aimed to estimate and compare the genetic diversity of four native Italian shepherd dog breeds: the Maremma, Bergamasco, Lupino del Gigante and Oropa shepherds. Therefore, some cosmopolitan dog breeds, which have been widely raised in Italy for a long time past, have also been considered to check possible influence of these dog populations on the Italian autochthonous breeds considered here. A total of 212 individuals, belonging to 10 different dog breeds, were sampled and genotyped using 18 autosomal microsatellite loci. We analyzed the genetic diversity of these breeds, within breed diversity, breed relationship and population structure. The 10 breeds considered in this study were clearly genetically differentiated from each other, regardless of current population sizes and the onset of separate breeding history. The level of genetic diversity explained 20% of the total genetic variation. The level of H E found here is in agreement with that found by other studies. The native Italian breeds showed generally higher genetic diversity compared with the long established, well-defined cosmopolitan dog breeds. As the Border Collie seems closer to the Italian breeds than the other cosmopolitan shepherd dogs considered here, a possible utilization of this breed to improve working performance in Italian traditional working shepherd dogs cannot be ignored. The data and information found here can be utilized in the organization of conservation programs planned to reduce inbreeding and to minimize loss of genetic variability.
Full Text Available The purpose of the article is to disclose the migratory threats which are connected with external and mass internal inter-regional migrations, which are caused by the annexation of the Crimea and military aggression in Donbas by Russia. Methodological and practical aspects of improving the management of intensive interstate and inter-regional migratory processes, negative consequences of which threaten national security of the country because of hybrid war in Donbas, illegal migration, worsening of the demographic situation, departure of scientists and specialists abroad are described in the article too. The main strategic objective, which consists of maintenance of state sovereignty, territorial integrity of Ukraine, and also integration in European and migratory space, ensuring close to the world standards of quality and length of life, realization of rights and freedoms of citizens, is formulated. Actions and tasks of the state migratory policy, ways and methods of regulation of external migrations of the population are considered. Principal reasons of external migrations of population are identified and analysed. The inwardly-regional, interregional and intergovernmental migrations of population of Ukraine in the years of its state independence (1991- 2014 are analyzed in details. The results of analysis showed that migratory activity goes down on inwardly-regional and interregional levels. Also intensity of exchange of population went down between the regions of country. At the same time Ukraine for years state independence through depopulation processes lost 6,5 million persons, and in the external migratory moving of population of loss made over 1 million persons. The problem of illegal external labour migration is considered.

Anthropogenic landscape features such as urban parks and gardens, landfills and farmlands can provide novel, seasonally reliable food sources that impact wildlife ecology and distributions. In historically migratory species, food subsidies can cause individuals to forgo migration and form partially migratory or entirely sedentary populations, eroding a crucial benefit of migration: pathogen avoidance through seasonal abandonment of transmission sites and mortality of infected individuals during migration. Since many migratory taxa are declining, and wildlife populations in urban areas can harbour zoonotic pathogens, understanding the mechanisms by which anthropogenic resource subsidies influence infection dynamics and the persistence of migration is important for wildlife conservation and public health. We developed a mathematical model for a partially migratory population and a vector-borne pathogen transmitted at a shared breeding ground, where food subsidies increase the nonbreeding survival of residents. We found that higher resident nonbreeding survival increased infection prevalence in residents and migrants, and lowered the fraction of the population that migrated. The persistence of migration may be especially threatened if residency permits emergence of more virulent pathogens, if resource subsidies reduce costs of infection for residents, and if infection reduces individual migratory propensity.This article is part of the theme issue 'Anthropogenic resource subsidies and host-parasite dynamics in wildlife'. © 2018 The Author(s).
Full Text Available Wuliangsuhai Lake provides important breeding and stopover habitats for shorebirds. The health of this wetland ecosystem is rapidly deteriorating due to eutrophication and water pollution and environmental management is urgently needed. To explore the connections among ecosystem health, prey density, and shorebird populations, we conducted surveys of both the benthic macroinvertebrates and shorebirds in the shorebird habitat of the wetland during the 2011 autumn migration season. The abundance of both shorebirds and benthic macroinvertebrates varied significantly in both space and time. Our data showed a clear association between shorebird populations and the density of benthic macroinvertebrates, which explained 53.63% of the variation in shorebird abundance. The prey density was strongly affected by environmental factors, including water and sediment quality. Chironomidae were mainly found at sites with higher total phosphorus, but with lower sediment concentrations of Cu. Lymnaeidae were mainly found at sites with a higher pH, lower salinity, and lower concentrations of total phosphorus and Cu. Habitats with very high concentrations of total phosphorus, heavy metals, or salinity were not suitable for benthic macroinvertebrates. Our findings suggest that the reductions of nutrient and heavy metal loadings are crucial in maintaining the ecological function of Wuliangsuhai as a stopover habitat for migratory shorebirds.

Documentation of spatial genetic discordance among breeding populations of Arctic-nesting avian species is important, because anthropogenic change is altering environmental linkages at micro- and macrogeographic scales. We estimated levels of population subdivision within Pacific Common Eiders (Somateria mollissima v-nigrum) breeding on 12 barrier islands in the western Beaufort Sea, Alaska, using molecular markers and capture—mark—recapture (CMR) data. Common Eider populations were genetically structured on a microgeographic scale. Regional comparisons between populations breeding on island groups separated by 90 km (Mikkelsen Bay and Simpson Lagoon) revealed structuring at 14 microsatellite loci (F ST = 0.004, P Sea are strongly philopatric to island groups rather than to a particular island. Despite the apparent high site fidelity of females, coalescence-based models of gene flow suggest that asymmetrical western dispersal occurs between island groups and is likely mediated by Mikkelsen Bay females stopping early on spring migration at Simpson Lagoon to breed. Alternatively, late-arriving females may be predisposed to nest in Simpson Lagoon because of the greater availability and wider distribution of nesting habitat. Our results indicate that genetic discontinuities, mediated by female philopatry, can exist at microgeographic scales along established migratory corridors.

Knowledge of the density-dependent processes that regulate animal populations is key to understanding, predicting, and conserving populations. In migratory birds, density-dependence is most often studied during the breeding season, yet we still lack a robust understanding of the reproductive traits through which density influences individual reproductive success. We used 27-yr of detailed, individual-level productivity data from an island-breeding population of Savannah sparrows Passerculus sandwichensis to evaluate effects of local and total annual population density on female reproductive success. Local density (number of neighbors within 50 m of a female's nest) had stronger effects on the number of young fledged than did total annual population density. Females nesting in areas of high local density were more likely to suffer nest predation and less likely to initiate and fledge a second clutch, which led to fewer young fledged in a season. Fledging fewer young subsequently decreased the likelihood of a female recruiting offspring into the breeding population in a subsequent year. Collectively, these results provide insight into the scale and reproductive mechanisms mediating density-dependent reproductive success and fitness in songbirds. © 2017 by the Ecological Society of America.

Full Text Available Abstract Background The role of migratory birds and of poultry trade in the dispersal of highly pathogenic H5N1 is still the topic of intense and controversial debate. In a recent contribution to this journal, Flint argues that the strict application of the scientific method can help to resolve this issue. Discussion We argue that Flint's identification of the scientific method with null hypothesis testing is misleading and counterproductive. There is far more to science than the testing of hypotheses; not only the justification, bur also the discovery of hypotheses belong to science. We also show why null hypothesis testing is weak and that Bayesian methods are a preferable approach to statistical inference. Furthermore, we criticize the analogy put forward by Flint between involuntary transport of poultry and long-distance migration. Summary To expect ultimate answers and unequivocal policy guidance from null hypothesis testing puts unrealistic expectations on a flawed approach to statistical inference and on science in general.

Inter-seasonal events are believed to connect and affect reproductive performance (RP) in animals. However, much remains unknown about such carry-over effects (COEs), in particular how behaviour patterns during highly mobile life-history stages, such as migration, affect RP. To address this question, we measured at-sea behaviour in a long-lived migratory seabird, the Manx shearwater (Puffinus puffinus) and obtained data for individual migration cycles over 5 years, by tracking with geolocator/immersion loggers, along with 6 years of RP data. We found that individual breeding and non-breeding phenology correlated with subsequent RP, with birds hyperactive during winter more likely to fail to reproduce. Furthermore, parental investment during one year influenced breeding success during the next, a COE reflecting the trade-off between current and future RP. Our results suggest that different life-history stages interact to influence RP in the next breeding season, so that behaviour patterns during winter may be important determinants of variation in subsequent fitness among individuals. © 2015 The Authors.
Full Text Available Based on thematic content analysis of textbooks, curricula, and an overview of educational legislation after the 1989 change of political regime in Romania, this paper presents empirical evidence to argue that that postsocialist citizenship education displays surprising similarities with converging post-war changes in the concept of the ‘good citizen’. The findings suggest a complex picture of change combining liberal, communitarian and cosmopolitan renditions of the new citizen, all having a common thread: the shift towards a post-national ethos delinking the citizen from the exclusive purchase of national belonging and decoupling citizen action from the absolute duty to the patria. Such significant changes are often overlooked due to the dominant focus on the failures to comply with an idealized Western liberal model. However, they invite us to reconsider current understandings of both the pitfalls and the opportunities of post-socialist citizenship education by considering them from a different angle: that of wider socio-cultural change that is gradually being institutionalised at the world level.

• Polyploidization frequently results in the creation of new plant species, the establishment of which is thought to often be facilitated by ecological niche differentiation from the diploid species. We tested this hypothesis using the cosmopolitan grass genus Phalaris (Poaceae), consisting of 19 species that range from diploid to tetraploid to hexaploid. Specifically, we tested whether (1) polyploids occupy more extreme environments and/or (2) have broader niche breadths and/or (3) whether the polyploid species' distributions indicate a niche shift from diploid species.• We employed a bootstrapping approach using distribution data for each species and eight environmental variables to investigate differences between species in the means, extremes, and breadths of each environmental variable. We used a kernel smoothing technique to quantify niche overlap between species.• Although we found some support for the three hypotheses for a few diploid-polyploid pairs and for specific environmental variables, none of these hypotheses were generally supported.• Our results suggest that these commonly held hypotheses about the effects of polyploidization on ecological distributions are not universally applicable. Correlative biogeographic studies like ours provide a necessary first step for suggesting specific hypotheses that require experimental verification. A combination of genetic, physiological, and ecological studies will be required to achieve a better understanding of the role of polyploidization in niche evolution. © 2015 Botanical Society of America, Inc.
Full Text Available In the last twenty years, the squatting movement in Rome has witnessed a steady increase of foreign participants as regular members but a scarce presence among the leadership. Moreover, the incidence of immigrants among squatters is typically not marked in the public self-representation of the movement yet overemphasized and disputed by mainstream media. The essay attempts an interpretation of this peculiar distribution of foreign immigrants among squatters. On the one side, their being foreigners within Italian welfare puts them at risk of higher exclusion; on the other, political leaders in the squats may see the foreigners (as bearers of a shared class condition as a suitable pool for the wider political aim of squatting, namely the implementation of an alternative urban lifestyle. Furthermore, foreigners may take part into squats just as a self-attained form of social emancipation, since the act of squatting may equal an otherwise inaccessible house possession. Within these apparently contradictory aims, multi-ethnic squats turn into cosmopolitan spaces of identities that accept transcending their specificities to pour into a common kiln of class identity, between revolutionary proletariat and pity bourgeoisie seeking full social integration.

Owing to the lack of temporally well-constrained Ediacaran fossil localities containing overlapping biotic assemblages, it has remained uncertain if the latest Ediacaran (ca 550–541 Ma) assemblages reflect systematic biological turnover or environmental, taphonomic or biogeographic biases. Here, we report new latest Ediacaran fossil discoveries from the lower member of the Wood Canyon Formation in Nye County, Nevada, including the first figured reports of erniettomorphs, Gaojiashania, Conotubus and other problematic fossils. The fossils are spectacularly preserved in three taphonomic windows and occur in greater than 11 stratigraphic horizons, all of which are below the first appearance of Treptichnus pedum and the nadir of a large negative δ13C excursion that is a chemostratigraphic marker of the Ediacaran–Cambrian boundary. The co-occurrence of morphologically diverse tubular fossils and erniettomorphs in Nevada provides a biostratigraphic link among latest Ediacaran fossil localities globally. Integrated with a new report of Gaojiashania from Namibia, previous fossil reports and existing age constraints, these finds demonstrate a distinctive late Ediacaran fossil assemblage comprising at least two groups of macroscopic organisms with dissimilar body plans that ecologically and temporally overlapped for at least 6 Myr at the close of the Ediacaran Period. This cosmopolitan biotic assemblage disappeared from the fossil record at the end of the Ediacaran Period, prior to the Cambrian radiation.

Individuals differ consistently in their behavioural reactions towards novel objects and new situations. Reaction to novelty is one part of a suit of individually consistent behaviours called coping strategies or personalities and is often summarised as bold or shy behaviour. Coping strategies could be particularly important for migrating birds exposed to novel environments on their journeys. We compared the average approach latencies to a novel object among migrants and residents in partially migratory blue tits Cyanistes caeruleus. In this test, we found migrating blue tits to have shorter approach latencies than had resident ones. Behavioural reactions to novelty can affect the readiness to migrate and short approach latency may have an adaptive value during migration. Individual behaviour towards novelty might be incorporated among the factors associated with migratory or resident behaviour in a partially migratory population.

The killing of large numbers of migratory bats at wind turbines is a pressing conservation problem. Even though avoidance and mitigation measures could benefit from a better knowledge of the species' migratory habits, we lack basic information about what habitats and corridors bats use during migration. We studied the isotopic niche dimensions of three bat species that are frequently killed at wind turbines in Germany: non-migratory Pipistrellus pipistrellus, mid-distance migratory Nyctalus noctula, and long- distance migratory Pipistrellus nathusii. We measured stable carbon and nitrogen isotope ratios (δ¹³C, δ¹⁵N) in five tissues that differed in isotopic retention time (fur, wing membrane tissue, muscle, liver, blood) to shed light on the species-specific habitat use during the autumn migration period using standard ellipse areas (SEAc). Further, we used stable isotope ratios of non-exchangeable hydrogen (δ²H(K)) in fur keratin to assess the breeding origin of bats. We inferred from isotopic composition (δ¹³C, δ¹⁵N) of fur keratin that isotopic niche dimensions of P. nathusii was distinct from that of N. noctula and P. pipistrellus, probably because P. nathusii was using more aquatic habitats than the other two species. Isoscape origin models supported that traveled distances before dying at wind turbines was largest for P. nathusii, intermediate for N. noctula, and shortest for P. pipistrellus. Isotopic niche dimensions calculated for each sample type separately reflected the species' migratory behavior. Pipistrellus pipistrellus and N. noctula showed similar isotopic niche breadth across all tissue types, whereas SEAc values of P. nathusii increased in tissues with slow turnaround time. Isotopic data suggested that P. nathusii consistently used aquatic habitats throughout the autumn period, whereas N. noctula showed a stronger association with terrestrial habitats during autumn compared to the pre-migration period.

Each spring, migratory herbivores around the world track or ‘surf’ green waves of newly emergent vegetation to distant summer or wet‐season ranges. This foraging tactic may help explain the great abundance of migratory herbivores on many seasonal landscapes. However, the underlying fitness benefits of this life‐history strategy remain poorly understood. A fundamental prediction of the green‐wave hypothesis is that migratory herbivores obtain fitness benefits from surfing waves of newly emergent vegetation more closely than their resident counterparts. Here we evaluate whether this behavior increases body‐fat levels – a critically important correlate of reproduction and survival for most ungulates – in elk Cervus elaphus of the Greater Yellowstone Ecosystem. Using satellite imagery and GPS tracking data, we found evidence that migrants (n = 23) indeed surfed the green wave, occupying sites 12.7 days closer to peak green‐up than residents (n = 16). Importantly, individual variation in surfing may help account for up to 6 kg of variation in autumn body‐fat levels. Our findings point to a pathway for anthropogenic changes to the green wave (e.g. climate change) or migrants’ ability to surf it (e.g. development) to impact migratory populations. To explore this possibility, we evaluated potential population‐level consequences of constrained surfing with a heuristic model. If green‐wave surfing deteriorates by 5–15 days from observed, our model predicts up to a 20% decrease in pregnancy rates, a 2.5% decrease in population growth, and a 30% decrease in abundance over 50 years. By linking green‐wave surfing to fitness and illustrating potential effects on population growth, our study provides new insights into the evolution of migratory behavior and the prospects for the persistence of migratory ungulate populations in a changing world.

In long-distance migratory systems, local fluctuations in the predator-prey ratio can exhibit extreme variability within a single year depending upon the seasonal location of migratory species. Such systems offer an opportunity to empirically investigate cyclic population density effects on short-term food web interactions by taking advantage of the large seasonal shifts in migratory prey biomass.We utilized a large-mammal predator-prey savanna food web to evaluate support for hypotheses relating to the indirect effects of "apparent competition" and "apparent mutualism" from migratory ungulate herds on survival of resident megaherbivore calves, mediated by their shared predator. African lions ( Panthera leo ) are generalist predators whose primary, preferred prey are wildebeests ( Connochaetes taurinus ) and zebras ( Equus quagga ), while lion predation on secondary prey such as giraffes ( Giraffa camelopardalis ) may change according to the relative abundance of the primary prey species.We used demographic data from five subpopulations of giraffes in the Tarangire Ecosystem of Tanzania, East Africa, to test hypotheses relating to direct predation and indirect effects of large migratory herds on calf survival of a resident megaherbivore. We examined neonatal survival via apparent reproduction of 860 adult females, and calf survival of 449 giraffe calves, during three precipitation seasons over 3 years, seeking evidence of some effect on neonate and calf survival as a consequence of the movements of large herds of migratory ungulates.We found that local lion predation pressure (lion density divided by primary prey density) was significantly negatively correlated with giraffe neonatal and calf survival probabilities. This supports the apparent mutualism hypothesis that the presence of migratory ungulates reduces lion predation on giraffe calves.Natural predation had a significant effect on giraffe calf and neonate survival, and could significantly affect giraffe

To overcome unpredictable stressful transitory events, animals trigger an allostatic response involving the hypothalamic-pituitary-adrenal cortex. This hormonal response, which involves the release of glucocorticoids which in turn mediate between the main physiological mechanisms that regulate the energetic demands and resource allocation trade-off with behavioural responses to environmental perturbations and may ultimately lead to variation in fitness. We have used the Cory's shearwater Calonectris borealis, a sexually dimorphic pelagic seabird with a partial migratory strategy, as a model bird species to analyse a number of traits related to the stress response. We investigated whether the activation of a stressful response, mediated by corticosterone, during the wintering period (1) correlated with the previous breeding success, (2) was affected by the migratory behaviour of male birds and (3) had consequences in the fitness of the birds. Corticosterone levels in feathers grown overwinter were analysed in 61 adult birds during three consecutive migratory periods (2009-2012) and in 14 immature birds in the wintering period 2010-2011. Moreover, the levels of corticosterone were analysed in experimental birds which were freed from their reproductive duties and compared with control birds which raised fledglings to the end of the breeding period. The results show that the levels of corticosterone were sex dependent, differed between years and were affected by the migratory strategy performed by the birds. The activation of the stressful response over the wintering period generated residual carry-over effects that positively affected the reproductive output in the subsequent breeding stage, a phenomenon previously undescribed in a long-lived pelagic seabird. Our study provides evidence that the analysis of corticosterone from feathers is a useful tool to evaluate carry-over effects in birds far away from breeding sites, opening new possibilities for future studies in

Full Text Available Deep sea scleractinian corals will be particularly vulnerable to the effects of climate change, facing loss of up to 70% of their habitat as the Aragonite Saturation Horizon (below which corals are unable to form calcium carbonate skeletons rises. Persistence of deep sea scleractinian corals will therefore rely on the ability of larvae to disperse to, and colonise, suitable shallow-water habitat. We used DNA sequence data of the internal transcribed spacer (ITS, the mitochondrial ribosomal subunit (16S and mitochondrial control region (MtC to determine levels of gene flow both within and among populations of the deep sea coral Desmophyllum dianthus in SE Australia, New Zealand and Chile to assess the ability of corals to disperse into different regions and habitats. We found significant genetic subdivision among the three widely separated geographic regions consistent with isolation and limited contemporary gene flow. Furthermore, corals from different depth strata (shallow 1500 m even on the same or nearby seamounts were strongly differentiated, indicating limited vertical larval dispersal. Genetic differentiation with depth is consistent with the stratification of the Subantarctic Mode Water, Antarctic Intermediate Water, the Circumpolar Deep and North Pacific Deep Waters in the Southern Ocean, and we propose that coral larvae will be retained within, and rarely migrate among, these water masses. The apparent absence of vertical larval dispersal suggests deep populations of D. dianthus are unlikely to colonise shallow water as the aragonite saturation horizon rises and deep waters become uninhabitable. Similarly, assumptions that deep populations will act as refuges for shallow populations that are impacted by activities such as fishing or mining are also unlikely to hold true. Clearly future environmental management strategies must consider both regional and depth-related isolation of deep-sea coral populations.

Every year, migratory species undertake seasonal movements along different pathways between discrete regions and habitats. The ability to assess the relative demographic contributions of these different habitats and pathways to the species’ overall population dynamics is critical for understanding the ecology of migratory species, and also has practical applications for management and conservation. Metrics for assessing habitat contributions have been well-developed for metapopulations, but an equivalent metric is not currently available for migratory populations. Here, we develop a framework for estimating the demographic contributions of the discrete habitats and pathways used by migratory species throughout the annual cycle by estimating the per capita contribution of cohorts using these locations. Our framework accounts for seasonal movements between multiple breeding and non-breeding habitats and for both resident and migratory cohorts. We illustrate our framework using a hypothetical migratory network of four habitats, which allows us to better understand how variations in habitat quality affect per capita contributions. Results indicate that per capita contributions for any habitat or pathway are dependent on habitat-specific survival probabilities in all other areas used as part of the migratory circuit, and that contribution metrics are spatially linked (e.g. reduced survival in one habitat also decreases the contribution metric for other habitats). Our framework expands existing theory on the dynamics of spatiotemporally structured populations by developing a generalized approach to estimate the habitat- and pathway-specific contributions of species migrating between multiple breeding and multiple non-breeding habitats for a range of life histories or migratory strategies. Most importantly, it provides a means of prioritizing conservation efforts towards those migratory pathways and habitats that are most critical for the population viability of

Highly pathogenic avian influenza virus (HPAIV) is a highly contagious disease which is a zoonotic pathogen of significant economic and public health concern. The outbreaks caused by HPAIV H5N1 of Asian origin have caused animal and human disease and mortality in several countries of Southeast Asia, such as Bangladesh, Cambodia, China, India, Indonesia, Laos, Myanmar, Thailand and Viet Nam. For the first time since 1961, this HPAIV has also caused extensive mortality in wild birds and has sparked debate of the role wild birds have played in the spread of this virus. Other than confirmed mortality events, little is known of this virus in wild birds. There is no report on the seroprevalence of avian influenza H5 infection in wild migratory birds in Yunnan Province. In this study we examined live wild birds in Yunnan Province for H5 specific antibody to better understand the occurrence of this disease in free living birds. Sera from 440 wild birds were collected from in Kunming and Northern Ailaoshan of Yunnan Province, Southwestern China, and assayed for H5 antibodies using the hemagglutination inhibition (HI) assays. The investigation revealed that the seroprevalence of avian influenza H5 was as following: Ciconiiformes 2.6%, Strigiformes 13.04%, Passeriformes 20%, Cuculiformes 21.74%, Gruiformes 0%, Columbiformes 0%, Charadriiformes 0% and Coraciiformes 0%. Statistical analyses showed that there was a significant difference of prevalence between the orders (P avian influenza H5 antibodies were detected in 23 of 440 (5.23%) sera. Mean HI titer 23 positive sera against H5 were 5.4 log₂. The results of the present survey indicated that the proportion of wild birds had previously infected AIV H5 at other times of the year. To our knowledge, this is the first seroprevalence report of avian influenza H5 infection in wild migratory birds in China' s southwestern Yunnan Province. The results of the present survey have significant public health concerns.

The EU Birds Directive and the African-Eurasian Waterbird Agreement provide an adequate legal framework for sustainable management of migratory waterbird populations. The main shortcoming of both instruments is that it leaves harvest decisions of a shared resource to individual Member States and Contracting Parties without providing a shared information base and mechanism to assess the impact of harvest and coordinate actions in relation to mutually agreed objectives. A recent update of the conservation status of waterbirds in the EU shows that almost half of the populations of species listed on Annex II of the Birds Directive have a declining short-term trend and over half of them are listed in Columns A and B of AEWA. This implies that their hunting could either only continue under the framework of an adaptive harvest management plan or their hunting should be regulated with the view of restoring them in favourable conservation status. We argue that a structured approach to decision-making (such as adaptive management) is needed, supported with adequate organisational structures at flyway scale. We review the experience with such an approach in North America and assess the applicability of a similar approach in the European context. We show there is no technical reason why adaptive harvest management could be not applied in the EU or even AEWA context. We demonstrate that an informed approach to setting allowable harvests does not require detailed demographic information. Essential to the process, however, are estimates of either the observed growth rate from a monitoring program or the growth rate expected under ideal conditions. In addition, periodic estimates of population size are needed, as well as either empirical information or reasonable assumptions about the form of density dependence. We show that such information exists for many populations, but improvements are needed to improve geographic coverage, reliability and timely data availability. We

Full Text Available For at-risk wildlife species, it is important to consider conservation within the process of adaptive management. Golden-winged Warblers (Vermivora chrysoptera are Neotropical migratory songbirds that are experiencing long-term population declines due in part to the loss of early-successional nesting habitat. Recently-developed Golden-winged Warbler habitat management guidelines are being implemented by USDA: Natural Resource Conservation Service (2014 and its partners through the Working Lands For Wildlife (WLFW program. During 2012–2014, we studied the nesting ecology of Golden-winged Warblers in managed habitats of the eastern US that conformed to WLFW conservation practices. We evaluated five NRCS “management scenarios” with respect to nesting success and attainment of recommended nest site vegetation conditions outlined in the Golden-winged Warbler breeding habitat guidelines. Using estimates of territory density, pairing rate, nest survival, and clutch size, we also estimated fledgling productivity (number of fledglings/ha for each management scenario. In general, Golden-winged Warbler nest survival declined as each breeding season advanced, but nest survival was similar across management scenarios. Within each management scenario, vegetation variables had little influence on nest survival. Still, percent Rubus cover and density of >2 m tall shrubs were relevant in some management scenarios. All five management scenarios rarely attained recommended levels of nest site vegetation conditions for Golden-winged, yet nest survival was high. Fledgling productivity estimates for each management scenario ranged from 2.1 to 8.6 fledglings/10 hectares. Our results indicate that targeted habitat management for Golden-winged Warblers using a variety of management techniques on private lands has the capability to yield high nest survival and fledgling productivity, and thus have the potential to contribute to the species recovery.

Acanthoscelides obtectus Say is a bruchid species of Neotropical origin, and is specialized on beans of the Phaseolus vulgaris L. group. Since the domestication and diffusion of beans, A. obtectus has become cosmopolitan through human-mediated migrations and is now a major pest in bean granaries. Using phylogeographic methods applied to mitochondrial DNA (mtDNA) and nuclear microsatellite molecular markers, we show that the origin of this species is probably further south than Mesoamerica, as commonly thought. Our results also indicate that A. obtectus and its Mesoamerican sister species Acanthoscelides obvelatus, two morphologically close species differing principally in voltinism, speciated in allopatry: A. obtectus (multivoltine) arising in Andean America and A. obvelatus (univoltine) in Mesoamerica. In contrast to Mesoamerica where beans fruit once yearly, wild beans in Andean America fruit year-round, especially in regions showing little or no seasonality. In such habitats where resources are continuously present, multivoltinism is adaptive. According to existing hypotheses, multivoltinism in A. obtectus is a new adaptation that evolved after bean domestication. Our data suggest the alternative hypothesis that multivoltinism is an older trait, adapted to exploit the year-round fruiting of wild beans in relatively aseasonal habitats, and allowed A. obtectus to become a pest in bean granaries. This trait also permitted this species to disperse through human-mediated migrations associated with diffusion of domesticated beans. We also show that diversity of Old World A. obtectus populations can be quite well explained by a single colonization event about 500 bp. Human-mediated migrations appear not to be rare, as our results indicate a second more recent migration event from Andean America to Mexico.

Protandry, the phenomenon of males arriving earlier at the breeding grounds than females, has been demonstrated in several migratory bird species. The pattern is linked to reproductive success and often ascribed to selection for securing the highest quality territories or mates. Protandry can...

Arctic amplification, the accelerated climate warming in the polar regions, is causing a more rapid advancement of the onset of spring in the Arctic than in temperate regions. Consequently, the arrival of many migratory birds in the Arctic is thought to become increasingly mismatched with the onset

The conservation of declining intercontinental landbird and shorebird migrants is complicated by the migratory nature of these organisms. Although debate over the causes of declines in most species will no doubt continue for some time, continued attention has focused largely on events associated with the breeding and wintering phases of the migrant's annual cycle...

To investigate the role of migratory birds in the dissemination of West Nile virus (WNV), we measured the prevalence of infectious WNV and specific WNV neutralizing antibodies in birds, principally Passeriformes, during spring and fall migrations in the Atlantic and Mississippi flyways from 2001-2003. Blood samples were obtained from 13,403 birds, representing 133 species. Specific WNV neutralizing antibody was detected in 254 resident and migratory birds, representing 39 species, and was most commonly detected in northern cardinals (Cardinalis cardinalis) (9.8%, N = 762) and gray catbirds (Dumetella carolinensis) (3.2%,N = 3188). West Nile virus viremias were detected in 19 birds, including 8 gray catbirds, and only during the fall migratory period. These results provide additional evidence that migratory birds may have been a principal agent for the spread of WNV in North America and provide data on the occurrence of WNV in a variety of bird species.

Livestock grazing is a widespread and important influence on neotropical migratory birds in four major ecosystems in western North America: grasslands of the Great Plains and Southwest, riparian woodlands, Intermountain shrubsteppe, and open coniferous forests. We have reviewed available literature on avian responses to grazing in these habitats. Among 35 plains...

Mid-winter movements of up to several hundreds of kilometres are typical for many migratory bird species wintering in Africa. Unpredictable temporary food concentrations are thought to result in random movements of such birds, whereas resightings and recoveries of marked birds suggest some degree of

Full Text Available This article examines assessments of the impact of the Fukushima nuclear power plant accident on exposure of the Russian Federation population related to the seasonal migration of game birds. Intake of artificial radionuclides with meat of migratory game birds is shown to be one of the major pathways for the population exposure in the Far Eastern region of the country.

Riparian forests have long been considered important habitats for breeding western landbirds, and growing evidence reinforces their importance during the migratory period as well. Extensive modification of natural flow regimes, grazing, and forest clearing along many rivers in the western U.S. have led to loss and simplification of native riparian forests and to...

The Green Wave Hypothesis posits that herbivore migration manifests in response to waves of spring green-up (i.e. green-wave surfing). Nonetheless, empirical support for the Green Wave Hypothesis is mixed, and a framework for understanding variation in surfing is lacking. In a population of migratory mule deer (Odocoileus hemionus), 31% surfed plant phenology in spring as well as a theoretically perfect surfer, and 98% surfed better than random. Green-wave surfing varied among individuals and was unrelated to age or energetic state. Instead, the greenscape, which we define as the order, rate and duration of green-up along migratory routes, was the primary factor influencing surfing. Our results indicate that migratory routes are more than a link between seasonal ranges, and they provide an important, but often overlooked, foraging habitat. In addition, the spatiotemporal configuration of forage resources that propagate along migratory routes shape animal movement and presumably, energy gains during migration. © 2017 John Wiley & Sons Ltd/CNRS.
