Available in PDF, EPUB and Kindle. Book excerpt: Les conséquences du changement climatique actuel sur les populations d’oiseaux ont fait l’objet de nombreux travaux au cours des deux dernières décennies. Ces études ont mis en évidence les principaux mécanismes de l’influence climatique sur les étapes du cycle de vie aviaire. Au cours de la thèse, nous avons tenté de proposer une vision intégrée de ces mécanismes et d’en explorer la variabilité interspécifique. Pour cela, nous avons utilisé les données du Suivi Temporel des Oiseaux Communs (STOC). Nous avons développé des outils d’analyse de la phénologie et de la survie à l’échelle des populations françaises. Nous avons ensuite exploré les liens qui relient l’ajustement phénologique aux conditions climatiques printanières et le taux de croissance à long terme des populations de passereaux communs et étudié la variabilité interspécifique de cet ajustement en examinant les corrélations avec les traits d’histoire de vie et les caractéristiques de la niche écologique des espèces. Nous trouvons que les espèces qui ajustent le mieux leur phénologie de reproduction à la température printanière possèdent les taux de croissance à long terme les plus élevés. La capacité d’ajustement phénologique est négativement corrélée à la distance de migration et au degré de spécialisation écologique des espèces alors qu’elle est positivement corrélée à la taille de leur cerveau. Nous nous sommes enfin intéressés à la sensibilité des populations au climat le long de l’aire de distribution afin de mieux comprendre les changements observés et attendus des aires de distributions chez les oiseaux et d’améliorer la qualité des prédictions de distributions futures sous scénario climatique

Download or read book Mediterranean Type Ecosystems written by George W. Davis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human activities are causing species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Exploring mediterranean-type ecosystems - the Mediterranean Basin, California, Chile, Australia, and South Africa - this volume addresses the question whether biological diversity plays a significant role in the functioning of natural ecosystems, and to what extent that diversity can be reduced without causing system malfunction. Comparative studies in ecosystems that are similar in certain respects, but differ in others, offer considerable scope for gaining new insights into the links between biodiversity and ecosystem functioning.

This book was released on 2016 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty years after the Convention on Biological Diversity (CBD) entered into force, the founding of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) in 2012 was the outcome of a long process of setting biodiversity issues at the top of the global environmental agenda. With contributions from more than a dozen well-renowned researchers in political science, law and sociology, this book analyzes IPBES functioning and challenges in terms of the knowledge selection process and actors involved. The book reveals that, through its conceptual framework, IPBES promotes a pluralistic view of nature that calls for a broadening of the disciplinary frontiers. It combines natural science and social science research and also includes indigenous and local knowledge. IPBES is considered to represent the institutionalization of a permanent knowledge assessment on biodiversity and is often referred to as an IPCC success story, constituting a new stage in global environmental governance. In analyzing the knowledge selection process for IPBES decision making, the book better situates IPBES within the biodiversity and global governance domain. It ultimately argues that the establishment of IPBES provides a new opportunity to coordinate the different international conventions (CBD, RAMSAR, CITES, etc.) and initiatives (international assessment of marine biology, scientific programs, funding, etc.).

Download or read book Bird Census Techniques written by Colin J. Bibby and published by Academic Press. This book was released on 2012-12-02 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild birds are counted for a wide variety of reasons and by a bewildering array of methods. However, detailed descriptions of the techniques used and the rationale adopted are scattered in the literature, and the newcomer to bird census work or the experienced bird counter in search of a wider view, may well have difficulty in coming to grips with the subject as a whole. While not an end in itself, numerical and distributional census work is a fundamental part of many scientific and conservation studies, and one in which the application of given standards is vital if results are not to be distorted or applied in a misleading way.This book provides a concise guide to the various census techniques and to the opportunities and pitfalls which each entails. The common methods are described in detail, and illustrated through an abundance of diagrams showing examples of actual and theoretical census studies. Anyone with a bird census job to plan should be able to select the method best suited to the study at hand, and to apply it to best effect within the limits inherent in it and the constraints of the particular study.The Royal Society for the Protection of Birds and the British Trust for Ornithology have for many years pioneered the collaboration of amateurs and professionals in various census studies. Three members of their staff, each with extensive field experience, now pool the knowledge of these investigations to lay the groundwork for sound census work in future years.

Download or read book Large Herbivore Ecology Ecosystem Dynamics and Conservation written by Kjell Danell and published by Cambridge University Press. This book was released on 2006-05-25 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most large herbivores require some type of management within their habitats. Some populations of large herbivores are at the brink of extinction, some are under discussion for reintroduction, whilst others already occur in dense populations causing conflicts with other land use. Large herbivores are the major drivers for forming the shape and function of terrestrial ecosystems. This 2006 book addresses the scientifically based action plans to manage both the large herbivore populations and their habitats worldwide. It covers the processes by which large herbivores not only affect their environment (e.g. grazing) but are affected by it (e.g. nutrient cycling) and the management strategies required. Also discussed are new modeling techniques, which help assess integration processes in a landscape context, as well as assessing the consequences of new developments in the processes of conservation. This book will be essential reading for all involved in the management of both large herbivores and natural resources.

Download or read book Is Japanese Related to Korean Tungusic Mongolic and Turkic written by Martine Irma Robbeets and published by Otto Harrassowitz Verlag. This book was released on 2005 with total page 980 pages. Available in PDF, EPUB and Kindle. Book excerpt: Where does Japanese come from? The linguistic origin of the Japanese language is among the most disputed questions of language history. One current hypothesis is that Japanese is an Altaic language, sharing a common ancestor with Korean, Tungusic, Mongolic and Turkic. But, the opinions are strongly polarized. Especially the inclusion of Japanese into this classification model is very much under debate. Given the lack of consensus in the field, this book presents a state of the art for the etymological evidence relating Japanese to Korean, Tungusic, Mongolic and Turkic. The different Altaic etymologies proposed in the scholarly literature are gathered in an etymological index of Japanese appended to this book. An item-by-item sifting of the evidence helps to hold down borrowings, universal similarities and coincidental look-alikes to a small percentage. When the remaining core-evidence is screened in terms of phonological regularity, the answer to the intriguing question is beginning to take shape.
