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.

Available in PDF, EPUB and Kindle. Book excerpt: Bird migration is one of the most astonishing feats in the natural world.

This book was released on 2013-06-29 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous experts including ecologists, geneticists, paleontologists and climatologists, investigate the response of terrestrial organisms to changes in their environment. The volume comprises an introductory and a final chapter by the editors as well as another 35 contributions. These are divided into six sections: 1. past environmental changes - the late-Quaternary; 2. spatial responses to past changes; 3. mechanisms enabling spatial responses; 4. evolutionary responses to past changes; 5. mechanisms enabling evolutionary responses; 6. predicted future environmental changes and simulated responses. The overwhelming and unanimous conclusion of all contributors is that forecasted global environmental changes pose a severe threat to the integrity of ecosystems worldwide and to the survival of at least some species.
