Available in PDF, EPUB and Kindle. Book excerpt: “Compulsively readable—a masterpiece, maybe the masterpiece of science journalism.” —Bill McKibben, Audubon A brilliant, stirring work, breathtaking in its scope and far-reaching in its message, The Song of the Dodo is a crucial book in precarious times. Through personal observation, scientific theory, and history, David Quammen examines the mysteries of evolution and extinction and radically alters our understanding of the natural world and our place within it. In this landmark of science writing, we learn how the isolation of islands makes them natural laboratories of evolutionary extravagance, as seen in the dragons of Komodo, the elephant birds of Madagascar, the giant tortoises of the Galapagos. But the dark message of island studies is that isolated ecosystems, whether natural or human-made, are also hotbeds of extinction. And as the world’s landscapes, from Tasmania to the Amazon to Yellowstone, are carved into pieces by human activity, the implications of this knowledge are more urgent than ever. An unforgettable scientific adventure, a fascinating account of an eight-year journey of discovery, and a wake-up call for our time, David Quammen’s The Song of the Dodo is an exquisitely written book that takes the reader on a globe-circling tour of wild places and extraordinary ideas.

Download or read book Ecological Principles of Nature Conservation written by I. Hansson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the first in a series entitled Conservation Ecology: Principles, Practices and Management, a theme which Elsevier's pioneer ing journal Biological Conservation has promoted since its foundation thirty-three years ago. The science of conservation ecology is now widely acknowledged as an essential component in the planning and develop ment of activities which change or modify our natural environment. Nevertheless in spite of much research and publicity, there is still a wide gap between theory and practice. Today it is especially important to try to bridge this gap by interpreting the results of ecological research so that they are understandable and relevant to a wide range of land managers, agriculturalists, foresters, and those working in the many categories of protected areas. The volumes in this series are designed to fulfil this purpose, and also to play an important educational role for students of the environmental sciences in schools, universities and other institutions.
Download or read book Audubon Wildlife Report 1987 written by Roger L. Di Silvestro and published by Academic Press. This book was released on 2013-10-02 with total page 717 pages. Available in PDF, EPUB and Kindle. Book excerpt: Audubon Wildlife Report 1987 covers important events that highlighted wildlife conservation in 1986. This book is an attempt by the National Audubon Society to gather together much of the diverse data about federal wildlife-policy administration, providing a vast array of data on federal wildlife management and comparative tables on the budgeting process. This text also examines many federal wildlife programs, from the migratory bird protection program, which in a sense gave birth to the federal role in wildlife conservation, to the endangered species program, called as the most important wildlife conservation effort in the world. This publication is valuable to conservationists and individuals interested in federal and state wildlife management.
Download or read book Minimum Animal Populations written by Hermann Remmert and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: H. REMMERT Small populations are very often discussed, but there seems to be no general overview touching all the self-evident but norma,lly simply neglected problems connected with small populations. First, there are many very different types of organisms, and as every biologist should know, the problems of small populations are very different in different types of organisms. 1. In vascular plants the problems are different from the situation in birds and mammals; in marine benthic animals or in parasites such as tapeworms the problems are different again, and in seasonal planktonic animals or insects they are different from those in biotopes under constant conditions. In tapeworms or in vascular plants, an adult organism seems to be comparable to a population of mammals or birds because its offspring can be so diverse and plentiful. 2. There are small populations which explode and break down to a small population again, and then explode and break down again.

Download or read book The Mammals of Texas written by David J. Schmidly and published by University of Texas Press. This book was released on 2016-08-09 with total page 737 pages. Available in PDF, EPUB and Kindle. Book excerpt: From reviews of previous editions: “This is the standard reference about Texas mammals.” —Wildlife Activist “A must for anyone seriously interested in the wildlife of Texas.” —Texas Outdoor Writers Association News “[This book] easily fills the role of both a field guide and a desk reference, and is written in a style that appeals to the professional biologist and amateur naturalist alike. . . . [It] should prove useful to anyone with an interest in the mammal fauna of Texas or the southern Great Plains.” —Prairie Naturalist The Mammals of Texas has been the standard reference since the first edition was coauthored by William B. Davis and Walter P. Taylor in 1947. Revised several times over the succeeding decades, it remains the most authoritative source of information on the mammalian wildlife of Texas, with physical descriptions and life histories for 202 species, abundant photographs and drawings, and distribution maps. In this new edition, David J. Schmidly is joined by one of the most active researchers on Texas mammals, Robert D. Bradley, to provide a thorough update of the taxonomy, distribution, and natural history of all species of wild mammals that inhabit Texas today. Using the most recent advances in molecular biology and in wildlife ecology and management, the authors include the most current information about the scientific nomenclature, taxonomy, and identification of species, while also covering significant advances in natural history and conservation.
Download or read book Ecosystem Management for Parks and Wilderness written by James K. Agee and published by University of Washington Press. This book was released on 1988 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for cooperation among government agencies as well as an interdisciplinary approach to the increasingly challenging and complicated problem of managing park and wilderness areas prompted the University of Washington College of Forest Resources, the National Park Service, and the Forest Service to sponsor an ecosystem management workshop for scientists, planners, and managers. To develop an improved conceptual approach to managing change in ecosystems crossing natural and political boundaries, the workshop focused on defining terms, uncovering areas of misunderstanding and barriers to cooperation, and developing methods to determine the most important problems and issues. Three needs emerged from the prioritization process: a precise definition of the management objectives for park and wilderness lands and how to integrate them with objectives for surrounding lands, nationally as well as site-specific; more information about physical, biological, and social components of park and wilderness ecosystems from both sides of political boundaries; and key indicators of ecosystem condition as well as methods for evaluating management effectiveness. All of these common themes point to a need for more precise direction in management goal setting and more accurate assessment of progress toward goals. The book includes an introductory chapter by the editors and summary in which they outline a direction for ecosystem management in the next critical decades. The other chapters by individual contributors include studies on laws governing park and wilderness lands, paleoecological records that reveal the historic effects of climatic variations on vegetation change, succession and natural disturbance in relation to the problems of what can and should be preserved, managing ecosystems for large populations of vertebrates, the management of large carnivores, effects of air pollution, lake acidification, human ecology and environmental management, the role of economics, cooperation in ecosystem management, and management challenges in Yellowstone National Park.
Download or read book Wild Thoughts from Wild Places written by David Quammen and published by Simon and Schuster. This book was released on 2012-10-16 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Wild Thoughts from Wild Places, award-winning journalist David Quammen reminds us why he has become one of our most beloved science and nature writers. This collection of twenty-three of Quammen's most intriguing, most exciting, most memorable pieces introduces kayakers on the Futaleufu River of southern Chile, where Quammen describes how it feels to travel in fast company and flail for survival in the river's maw. Readers learn of the commerce in pearls (and black-market parrots) in the Aru Islands of eastern Indonesia. Quammen even finds wildness in smog-choked Los Angeles -- embodied in an elusive population of urban coyotes, too stubborn and too clever to surrender to the sprawl of civilization. With humor and intelligence, David Quammen's Wild Thoughts from Wild Places also reminds us that humans are just one of the many species on earth with motivations, goals, quirks, and eccentricities. Expect to be entertained and moved on this journey through the wilds of science and nature.
