Book Synopsis Ecology and Conservation of Neotropical Migrant Landbirds by : Manomet Bird Observatory (Mass.)
Download or read book Ecology and Conservation of Neotropical Migrant Landbirds written by Manomet Bird Observatory (Mass.). This book was released on 1992. Available in PDF, EPUB and Kindle. Book excerpt: For more than a decade ornithologists have suspected that migrant landbird populations in the United States and Canada are declining. Fragmented forests in the northern breeding grounds and the loss of habitats in tropical wintering zones have been suggested as two major factors in the population declines. This is the first technical volume to focus exclusively on the question of northern hemispheric migratory landbird declines and their conservation. More than one hundred leading scholars working in the Americas and the Caribbean report on the problems facing these birds and suggest strategies for research and conservation. The book details the basic ecology of many Neotropical migrant landbirds in both temperate and tropical regions. Individual reports--each with a Spanish abstract--probe the reasons for population changes, discuss species behavior during summer and winter months, and gauge the impact of environmental events on landbirds. This book arose out of a 1989 symposium at Woods Hole, Massachusetts, hosted by the Manomet Bird Observatory--a meeting widely credited for bringing Neotropical migrant landbird conservation to the forefront of attention.

Book Synopsis Population Ecology, Habitat Requirements, and Conservation of Neotropical Migratory Birds by : Deborah M. Finch
Download or read book Population Ecology, Habitat Requirements, and Conservation of Neotropical Migratory Birds written by Deborah M. Finch. This book was released on 1991. Available in PDF, EPUB and Kindle. Book excerpt: This report was prepared in support of the National Fish and Wildlife Foundation's Neotropical Migratory Bird Conservation Program and the USDA Forest Service's role in the program. Recent analyses of data on forest-dwelling species, many of which are neotropical migrants, show population declines in many North American areas. The literature review summarizes current information on population trends of neotropical migratory birds and the factors affecting migrant populations on the breeding and wintering grounds. Opportunities for research, monitoring, and conservation of these migrants on Forest Service lands are discussed.

Book Synopsis Ecology and Management of Neotropical Migratory Birds by : Thomas E. Martin
Download or read book Ecology and Management of Neotropical Migratory Birds written by Thomas E. Martin. This book was released on 1995-10-19. Available in PDF, EPUB and Kindle. Book excerpt: The apparent decline in numbers among many species of migratory songbirds is a timely subject in conservation biology, particularly for ornithologists, ecologists, and wildlife managers. This book is an attempt to discuss the problem in full scope. It presents an ambitious, comprehensive assessment of the current status of neotropical migratory birds in the U.S., and the methods and strategies used to conserve migrant populations. Each chapter is an essay reviewing and assessing the trend from a different viewpoint, all written by leaders in the fields of ornithology, conservation, and population biology.

Book Synopsis Birds of Two Worlds by : Russell Greenberg
Download or read book Birds of Two Worlds written by Russell Greenberg. This book was released on 2005-05-02. Available in PDF, EPUB and Kindle. Book excerpt: For centuries biologists have tried to understand the underpinnings of avian migration: where birds go and why, why some migrate and some do not, how they adapt to a changing environment, and how migratory systems evolve. Twenty-five years ago the answers to many of these questions were addressed by a collection of migration experts in Keast and Morton's classic work Migrant Birds in the Neotropics. In 1992, Hagan and Johnston published a follow-up book, Ecology and Conservation of Neotropical Migrant Landbirds. In Birds of Two Worlds Russell Greenberg and Peter Marra bring together the world's experts on avian migration to discuss its ecology and evolution. The contributors move the discussion of migration to a global stage, looking at all avian migration systems and delving deeper into the evolutionary foundations of migratory behavior. Readers interested in the biology, behavior, ecology, and evolution of birds have waited a decade to see a worthy successor to the earlier classics. Birds of Two Worlds will complete the trilogy and become indispensable for ornithologists, evolutionary biologists, serious birders, and public and academic libraries.
