Book Synopsis Evolutionary Differentiation in Morphology, Vocalizations, and Allozymes Among Nomadic Sibling Species in the North American Red Crossbill (Loxia Curvirostra) Complex by : Jeffrey G. Groth
Download or read book Evolutionary Differentiation in Morphology, Vocalizations, and Allozymes Among Nomadic Sibling Species in the North American Red Crossbill (Loxia Curvirostra) Complex written by Jeffrey G. Groth and published by Univ of California Press. This book was released on 1993-08-16 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: The highly variable North American red crossbill complex has presented one of the most controversial problems in avian systematics. Although crossbills wander nomadically and breed all year, they have not become homogenized in bill and body size. This study suggests that this crossbill complex contains several distinctive sibling species that breed sympatrically and show ecological differences.
Book Synopsis Restoring North America's Birds by : Robert Askins
Download or read book Restoring North America's Birds written by Robert Askins and published by Yale University Press. This book was released on 2002-01-01 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: This accessible book draws on recent research on bird species and their habitats to explain how basic principles of bird ecology and landscape ecology can help us create scientifically sound plans for protecting and restoring the rich diversity of North American birds. This edition includes an afterword that reviews noteworthy literature that has appeared since the first edition was completed in 1999. This new material--on such key issues as the importance of preserving large expanses of natural habitat, the importance of maintaining early successional habitats, and the habitat requirements of neotropical migrants--shows how the research on landscape ecology of birds has shaped conservation policy more rapidly than most would have predicted. Praise for the earlier edition: "This book is first-rate--very broad in scope and appeal, readable, and truly integrative in its coverage of landscape ecology and its implications for avian conservation biology. . . . It will be of significant interest to researchers and students of conservation biology, ornithology and ecology; land managers; conservation agencies; and anyone with an interest in protecting the rich avian diversity of North America."--Trevor E. Pitcher, American Scientist "This wonderful book . . . is especially relevant for conservation biologists from all walks of life."--Kathryn E. Sieving, Auk "An enjoyable read for anyone, from the amateur birder to the professional scientist."--J. Michael Reed, Ecology
Book Synopsis Sibling Species of Titmice in the Parus Inornatus Complex (Aves by : Carla Cicero
Download or read book Sibling Species of Titmice in the Parus Inornatus Complex (Aves written by Carla Cicero and published by Univ of California Press. This book was released on 1996-04-08 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a comprehensive investigation of macrogeographic variation in the Plain Titmouse (Parus inornatus) complex in western North America, the author assessed population-level patterns of differentiation in morphometric, colorimetric, allozymic, mtDNA, and vocal characters. These suites of traits showed broad geographic concordance, distinguishing Pacific slope from interior populations. These two groups of populations are treated as sibling species.
Download or read book The Canary written by Goncalo C. Cardoso and published by Elsevier. This book was released on 2023-11-26 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Canary: Natural History, Science and Cultural Significance covers the ecology, evolution and conservation of the canary and related species, along with the history and cultural significance of the domestic canary worldwide and various scientific disciplines in which canaries have played a key role as a model species. The book synthesizes the multiple ways in which the canary and its relatives have been, and continue to be, an important scientific model in diverse areas and have influenced human culture. Each chapter is written by international experts in areas such as biogeography, animal behavior, evolutionary ecology, conservation, neurobiology, genetics, or ethnology. In covering this eclectic array of topics, while always focusing on the canary and its close relatives, this book uses the immense appeal of the canary as a vehicle to present notions of ecology, evolution, biodiversity conservation, and so on, to a wide audience. - Details all aspects of Crithagra and Serinus canaries as well as relatives like crossbills - Structured to begin with more accessible topics like natural history, domestication, and conservation - Closes with discussions of more specialized topics like evolution, neurobiology, behavior and genomics

Download or read book Endless Forms written by Daniel J. Howard and published by Oxford University Press, USA. This book was released on 1998 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Speciation is one of the great themes of evolutionary biology. It is the process through which new species are born and diversity generated. Yet for many years our understanding of the process consisted of little more than a perception that if populations are isolated geographically, they will diverge genetically and may come to form new species. This situation began to change in the 1960s as an increasing number of biologists challenged the exclusivity of allopatric speciation and began to probe more deeply into the actual process by which divergence occurs and reproductive isolation is acquired. This focus on process led to many new insights, but numerous questions remain and speciation is now one of the most dynamic areas of research in modern evolutionary biology. This volume presents the newest research findings on speciation bringing readers up to day on species concepts, modes of speciation, and the nature of reproductive barriers. It also discusses the forces that drive divergence of populations, the genetic control of reproductive isolation, and the role played by hybrid zones and hybridization in speciation.
