In recent years, a number of studies have highlighted that the life cycle and behaviour of organisms are changing as a result of global warming. Birds appear to be suitable models to detect these changes because this taxonomic group is particularly well documented, with a large amount of biological datasets available over long periods. Among them, those collected at migration watchsites are particularly valuable to detect long term phenological changes and population trends of migratory birds, but these data have been poorly considered so far. In this thesis, an exhaustive inventory of monitoring watchsites in France is first performed; we then determined the minimum requirements to use such heterogeneous datasets in order to reliably estimate changes in bird phenology and population. We showed that short-distance migrants have lengthened their breeding area residence time and have shortened their migration distances. It suggests that these birds may become resident close to their breeding sites. In addition, we demonstrated that these changes in migratory behaviour do not always occur linearly or gradually, but often abruptly, suddenly, and in a synchronous way (e.g. circa 1995). Such changes are both the cause and the consequence of a dynamical reorganization of ecosystems identified through food webs, indicating a large-scale response of ecosystems to climate change.

Climate change issues are attracting rapidly increasing interest from a wide range of biologists due to their unprecedented effects on global biodiversity, although there remains a lack of general knowledge as to the environmental consequences of such rapid change. Compared with any other class of animals, birds provide more long-term data and extensive time series, a more geographically and taxonomically diverse source of information, a richer source of data on a greater range of topics dealing with the effects of climate change, and a longer tradition of extensive research. The first edition of the book was widely cited and this new edition continues to provide an exhaustive and up-to-date synthesis of our rapidly expanding level of knowledge as it relates to birds, highlighting new methods and areas for future research.

Chez les oiseaux, les changements environnementaux ont un impact sur leur distribution, leur abondance et sur les mécanismes démographiques, physiologiques et comportementaux. Richement illustré, cet ouvrage présente de manière claire, mais scientifiquement fondée, le pour et le contre des nouveaux cadres de vie auxquels les oiseaux sont confrontés, ainsi que certains des mécanismes qui leur permettent de s’y adapter.

P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological biological observation station in the world (see first chapter "In Memory of Vogelwarte Rossitten"). This area later received enormous impetus when ex perimental research on the subject was begun: the large-scale bird-ringing experiment initiated in Rossitten in 1903 by Johannes Thienemann (who was inspired by the pioneering studies of C. C. M. Mortensen), the experiments on photoperiodicity carried out by William Rowan in the 1920s in Canada and retention and release experiments performed by Thienemann in the 1930s in Rossitten, the first experimental study on the orientation of migratory birds. After the Second World War, migration research, while continuing in the previous areas, also expanded into new directions such as radar ornithology, ecophysiology and hormonal control mechanisms, studies of evolution, ge netics, telemetry and others.

Temperature and other climate variables are currently changing at a dramatic rate. As observations have shown, these climatic changes have serious consequences for all organisms and their ability to adapt to changing environmental conditions. Birds are excellent model organisms, with a very active metabolism, they are highly sensitive to environmental changes and as highly mobile creatures they are also extremely reactive. Birds and Climate Change discusses our current knowledge of observed changes and provides guidelines for studies in the years to come so we can document and understand how patterns of changing weather conditions may affect birds. Provides reviews of long-term datasets Incorporates meta-analyses of studies about climate change effects on birds Includes guidelines and suggestions for further studies

Changes in seasonal movements and population dynamics of migratory birds in response to ongoing changes resulting from global climate changes are a topic of great interest to conservation scientists and birdwatchers around the world. Because of their dependence on specific habitats and resources in different geographic regions at different phases of their annual cycle, migratory species are especially vulnerable to the impacts of climate change. In Bird Migration and Global Change, eminent ecologist George W. Cox brings his extensive experience as a scientist and bird enthusiast to bear in evaluating the capacity of migratory birds to adapt to the challenges of a changing climate. Cox reviews, synthesizes, and interprets recent and emerging science on the subject, beginning with a discussion of climate change and its effect on habitat, and followed by eleven chapters that examine responses of bird types across all regions of the globe. The final four chapters address the evolutionary capacity of birds, and consider how best to shape conservation strategies to protect migratory species in coming decades. The rate of climate change is faster now than at any other moment in recent geological history. How best to manage migratory birds to deal with this challenge is a major conservation issue, and Bird Migration and Global Change is a unique and timely contribution to the literature.

Les conséquences du changement climatique actuel sur la biodiversité font l’objet de nombreuses études depuis la fin des années 1990. Certaines d’entre elles ont mis en évidence un déplacement de l’aire de distribution des espèces. Or, les changements climatiques prédits pour la fin du siècle devraient s’accélérer. L’objectif de la thèse était de prédire l’impact potentiel de ces changements climatiques futurs sur la distribution et la diversité des oiseaux européens. Une première partie de mes travaux a porté sur des aspects méthodologiques ayant pour objectif l’amélioration des prédictions d’aires de distribution actuelles. Je me suis ensuite intéressée aux problèmes pouvant résulter de la projection sous scénario futur, lorsque la niche actuelle est biaisée, mais également à l’importance de considérer les capacités de dispersion des espèces. Dans un deuxième temps, l’application de ces différentes méthodes au niveau monospécifique m’a permis de mettre en évidence que la Sittelle corse devrait plus souffrir de la destruction de son habitat que des changements climatiques. Au niveau multispécifique, l’impact des changements globaux devrait être très important sur les aires de reproduction de l’ensemble des oiseaux terrestres nicheurs européens ainsi que sur les aires d’hivernage sub-sahariennes des passereaux européens. A partir de ces prédictions pour l’ensemble d’un groupe sur toute l’Europe, l’étude des assemblages d’espèces révèle que les assemblages futurs sur tout le bassin méditerranéen ne seront analogues à aucun assemblage actuel. Enfin, l’étude portant sur l’évolution prédite de diversité fonctionnelle s’avère complémentaire de celle sur la richesse spécifique
