Available in PDF, EPUB and Kindle. Book excerpt: Speciation is the process by which co-existing daughter species evolve from one ancestral species - e.g., humans, chimpanzees, and gorillas arising from a common ancestor around 5,000,000 years ago. However, many questions about speciation remain controversial. The Birds of Northern Melanesia provides by far the most comprehensive study yet available of a rich fauna, composed of the 195 breeding land and fresh-water bird species of the Bismarck and Solomon Archipelagoes east of New Guinea. This avifauna offers decisive advantages for understanding speciation, and includes famous examples of geographic variation discussed in textbooks of evolutionary biology. The book results from 30 years of collaboration between the evolutionary biologist Ernst Mayr and the ecologist Jared Diamond. It shows how Northern Melanesian bird distributions provide snapshots of all stages in speciation, from the earliest (widely distributed species without geographic variation) to the last (closely related, reproductively isolated species occurring sympatrically and segregating ecologically). The presentation emphasizes the wide diversity of speciation outcomes, steering a middle course between one-model-fits-all simplification and ungeneralizable species accounts. Questions illuminated include why some species are much more prone to speciate than others, why some water barriers are much more effective at promoting speciation than others, and whether hypothesized taxon cycles, faunal dominance, and legacies of Pleistocene land bridges are real. These years of study have resulted in a huge database, complete with distributions of all 195 species on 76 islands, together with their taxonomy, colonization routes, ecological attributes, abundance, and overwater dispersal. Color plates depict 88 species and allospecies, many of which have never been seen before. For students of speciation, Northern Melanesian birds now constitute a model system against which other biotas can be compared. For population biologists interested in other problems besides speciation, this rich database can now be mined for insights.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the first detailed biography of Ernst Mayr. He was an ‘architect’ of the Synthetic Theory of Evolution, and the greatest evolutionary biologist since Charles Darwin, influential historian and philosopher of biology, outstanding taxonomist and ornithologist, and naturalist. He is one of the most widely known biologists of the 20th century. Mayr used the theories of natural selection and population thinking as theoretical models within the framework of historical biological studies. He was the first to emphasize the role of biopopulations, thereby pointing out the basic difference between ’population thinking’ and typological essentialism.

Download or read book Birds of New Guinea written by Bruce M. Beehler and published by Princeton University Press. This book was released on 2016-03-29 with total page 673 pages. Available in PDF, EPUB and Kindle. Book excerpt: New Guinea, the largest tropical island, supports a spectacular bird fauna characterized by cassowaries, megapodes, pigeons, parrots, kingfishers, and owlet-nightjars, as well as the iconic birds of paradise and bowerbirds. Of the nearly 800 species of birds recorded from New Guinea, more than 350 are found nowhere else on Earth. This comprehensive annotated checklist of distribution, taxonomy, and systematics of the birds of New Guinea is the first formal review of this avifauna since Ernst Mayr's Checklist, published in 1941. This new book brings together all the systematic, taxonomic, and distributional research conducted on the region's bird families over the last 70 years. Bruce Beehler and Thane Pratt provide the scientific foundation for the names, geographic distributions, and systematic arrangement of New Guinea's bird fauna. All technical information is annotated and a geographic gazetteer and bibliography are included. This book is an ideal complement to the Birds of New Guinea field guide also published by Princeton, and is an essential technical reference for all scientific libraries, ornithologists, and those interested in bird classification. The first complete revision of the New Guinea bird fauna since 1941 Accounts for 75 bird species new to the region Includes a geographic gazetteer, bibliography, and explanations of taxonomic and systematic classifications
