Download or read book Les ailes du Sahel written by Le Zwarts and published by BRILL. This book was released on 2014-04-14 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Living on the Edge' examines the function of the Sahel region of Africa as an important wintering area for long-distance migrant birds. It describes the challenges the birds have to cope with – climate change, of course, and rapid man-made habitat changes related to deforestation, irrigation and reclamation of wetlands. How have all these changes affected the birds, and have birds adapted to these changes? Can we explain the changing numbers of breeding birds in Europe by changes in the Sahel, or vice versa? Winner of the BB/BTO Best Bird Book Award 2010 The Jury commented: "It is a tremendous book in every department. It marks a step-change in our knowledge of the ecology of this critically important region in the European-African migration system and of the many species (familiar to us on their breeding grounds) that winter there. The authors combine the latest scientific information with vivid descriptions of landscapes and animals. Their book is richly illustrated with large numbers of drawings, maps and photographs by acclaimed experts. The wealth of coloured graphics has been particularly well thought out and encourages readers to delve into the figures and learn more about the region, rather than having the (all-too-common) opposite effect. Summing up, the jury praises not just the high quality of the texts, the information and the illustrations, but also the sheer pleasure of reading the book: "One of the key attributes of a good book is to be able to grip the reader's attention and transport him or her to another place. We feel confident that [Living on the edge] will have that effect."
Download or read book Bird Migration written by John H. Rappole and published by JHU Press. This book was released on 2022-02-22 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fascinating and nuanced exploration of why, how, and which birds migrate. Bird migration captivates the human imagination, yet for most of us, key aspects of the phenomenon remain a mystery. How do birds sense the ideal moment to take wing, and once the epic journey has begun, how do they find their distant destinations? Fresh insights about avian movements are still constantly emerging, powered by new tools like molecular genetics and transmitter miniaturization. In this book, renowned ornithologist and author John H. Rappole reveals intriguing results of recent scientific studies on migration, explaining their importance for birders, nature lovers, and researchers alike. Debunking misconceptions about the lives of birds that have persisted for thousands of years, Rappole explores unexpected causes and previously misunderstood aspects of the annual migration cycle. From the role of migrating birds in zoonotic disease transmission to climate change's impact on migration patterns, Rappole tackles crucial questions and ensures that readers come away with a new understanding of why and how birds migrate.
Download or read book Gatherings of Angels written by Kenneth P. Able and published by Cornell University Press. This book was released on 1999 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The migration of birds has forever amazed and confounded onlookers. How do birds find their way to their destinations? How do they withstand the dangers and rigors of long-distance flight? The survival of migrant birds is increasingly threatened by environmental degradation and manmade hazards; their protection is more critical than ever. Gatherings of Angels offers first-hand accounts by leading experts who convey the beauty and excitement of migration while communicating important messages about avian conservation. The book features twenty-four pages of stunning color photographs with additional black-and-white photographs throughout.Two chapters of background information on migration precede chapters that focus on different species or groups of birds and the localities essential to their survival--from the spring flights of songbirds across the Gulf of Mexico to the massing of sandhill cranes on the Platte River. The authors discuss the timing of migrant travel; the routes followed; and the concentration of birds in stop-over sites, locations that must be preserved if they are to have secure resting spots with fresh water and ample food to fuel their journey.
Download or read book Bird Migration written by Eberhard Gwinner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: E. GWINNER! The phenomenon of bird migration with its large scale dimensions has attracted the attention of naturalists for centuries. Worldwide billions of birds leave their breeding grounds every autumn to migrate to areas with seasonally more favor able conditions. Many of these migrants travel only over a few hundred kilo meters but others cover distances equivalent to the circumference of the earth. Among these long-distance migrants are several billion birds that invade Africa every autumn from their West and Central Palaearctic breeding areas. In the Americas and in Asia the scope of bird migration is of a similar magnitude. Just as impressive as the numbers of birds are their achievements. They have to cope with the enormous energetic costs of long-distance flying. particularly while crossing oceans and deserts that do not allow replenishment of depleted fat reserves. They have to appropriately time the onset and end of migrations. both on a daily and annual basis. And finally. they have to orient their migratory movements in space to reach their species- or population-specific wintering and breeding grounds, irrespective of the variable climatic conditions along their migratory routes.
Download or read book Bird Migration across the Himalayas written by Herbert H. T. Prins and published by Cambridge University Press. This book was released on 2017-04-06 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birds migrating across the Himalayan region fly over the highest peaks in the world, facing immense physiological and climatic challenges. The authors show the different strategies used by birds to cope with these challenges. Many wetland avian species are seen in the high-altitude lakes of the Himalayas and the adjoining Tibetan Plateau, such as Bar-Headed Geese. Ringing programmes have generated information about origins and destinations, and this book is the first to present information on the bird's exact migratory paths. Capitalising on knowledge generated through satellite telemetry, the authors describe the migratory routes of a multitude of birds flying over or skirting the Himalayas. The myriad of threats to migratory birds and the wetland system in the Central Asian Flyway are discussed, with ways to mitigate them. This volume will inform and persuade policy-makers and conservation practitioners to take appropriate measures for the long-term survival of this unique migration.

Download or read book Natura 2000 et le juge Natura 2000 and the judge written by Charles-Hubert Born and published by Primento. This book was released on 2014-06-05 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: S’inscrivant dans le cadre des activités de l’Observatoire juridique Natura 2000, le thème du présent ouvrage porte sur les questions juridiques que soulève l’application par le juge national – constitutionnel, administratif et judiciaire – des dispositions relatives à Natura 2000, en vue d’évaluer la contribution du juge à l’effectivité de ces dernières. Corps de règles complexe, technique, faisant appel à des concepts scientifiques ardus à interpréter pour un non-scientifique, le régime Natura 2000 n’est guère aisé à appliquer pour un juge non spécialisé. Le recours à l’expertise est souvent indispensable pour déterminer dans quelle mesure tel ou tel standard – par exemple le caractère « significatif » d’un impact – a été respecté ou non. Pour cette raison, les solutions trouvées par le juge aux différents problèmes que pose l’application du régime Natura 2000 dans les différents États membres méritent l’attention et sera enrichissante tant pour le chercheur que pour le praticien. As part of the activities of the Legal Observatory Natura 2000, this book focuses on legal issues arising from the implementation by the national courts – constitutional, administrative and judicial ones – of the provisions relating to Natura 2000, in order to assess the contribution of the judge to the effectiveness of this regime. The enforcement of this legislation, which encompasses a complex body of technical rules, grounded on scientific concepts difficult to interpret for a non-scientist, is not easy to apply by a non-specialized judge. The use of expertise is essential to determine how a particular standard – for example the «significant» character of an impact – has been met or not. For this reason, the solutions found by the judge to the various problems arising from the application of the Natura 2000 provisions in the different Member States deserve attention and will be rewarding for both researchers and practitioners.
