Available in PDF, EPUB and Kindle. Book excerpt: The world's first national park, Yellowstone is a symbol of nature's enduring majesty and the paradigm of protected areas across the globe. But Yellowstone is constantly changing. How we understand and respond to events that are putting species under stress, say the authors of Yellowstone's Wildlife in Transition, will determine the future of ecosystems that were millions of years in the making. With a foreword by the renowned naturalist E. O. Wilson, this is the most comprehensive survey of research on North America's flagship national park available today. Marshaling the expertise of over thirty contributors, Yellowstone's Wildlife in Transition examines the diverse changes to the park's ecology in recent decades. Since its creation in the 1870s, the priorities governing Yellowstone have evolved, from intensive management designed to protect and propagate depleted large-bodied mammals to an approach focused on restoration and preservation of ecological processes. Recognizing the importance of natural occurrences such as fires and predation, this more ecologically informed oversight has achieved notable successes, including the recovery of threatened native species of wolves, bald eagles, and grizzly bears. Nevertheless, these experts detect worrying signs of a system under strain. They identify three overriding stressors: invasive species, private-sector development of unprotected lands, and a warming climate. Their concluding recommendations will shape the twenty-first-century discussion over how to confront these challenges, not only in American parks but for conservation areas worldwide. Highly readable and fully illustrated, Yellowstone's Wildlife in Transition will be welcomed by ecologists and nature enthusiasts alike.

Download or read book Cutthroat written by Pat Trotter and published by Univ of California Press. This book was released on 2008 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cutthroat tells the full story of the genuine native trout of the American West. This new edition, thoroughly revised and updated after 20 years, synthesizes what is currently known about one of our most interesting and colorful fishes, includes much new information on its biology and ecology, asks how it has fared in the last century, and looks toward its future. In a passionate and accessibly written narrative, Patrick Trotter, fly fisher, environmental advocate, and science consultant, details the evolution, natural history, and conservation of each of the cutthroat's races and incorporates more personal reflections on the ecology and environmental history of the West's river ecosystems. The bibliography now includes what may be the most comprehensive and complete set of references available anywhere on the cutthroat trout. Written for anglers, nature lovers, environmentalists, and students, and featuring vibrant original illustrations by Joseph Tomelleri, this is an essential reference for anyone who wants to learn more about this remarkable, beautiful, and fragile western native.

Download or read book Science and Ecosystem Management in the National Parks written by William L. Halvorson and published by University of Arizona Press. This book was released on 2023-01-17 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our national parks are more than mere recreational destinations. They are repositories of the nation's biological diversity and contain some of the last ecosystem remnants needed as standards to set reasonable goals for sustainable development throughout the land. Nevertheless, public pressure for recreation has largely precluded adequate research and resource monitoring in national parks, and ignorance of ecosystem structure and function in parks has led to costly mistakes--such as predator control and fire suppression--that continue to threaten parks today. This volume demonstrates the value of ecological knowledge in protecting parks and shows how modest investments in knowledge of park ecosystems can pay handsome dividends. Science and Ecosystem Management in the National Parks presents twelve case studies of long-term research conducted in and around national parks that address major natural resource issues. These cases demonstrate how the use of longer time scales strongly influence our understanding of ecosystems and how interpretations of short-term patterns in nature often change when viewed in the context of long-term data sets. Most importantly, they show conclusively that scientific research significantly reduces uncertainty and improves resource management decisions. Chosen by scientists and senior park managers, the cases offer a broad range of topics, including: air quality at Grand Canyon; interaction between moose and wolf populations on Isle Royale; control of exotic species in Hawaiian parks; simulation of natural fire in the parks of the Sierra Nevada; and the impact of urban expansion on Saguaro National Monument. Because national parks are increasingly beset with conflicting views of their management, the need for knowledge of park ecosystems becomes even more critical--not only for the parks themselves, but for what they can tell us about survival in the rest of our world. This book demonstrates to policymakers and managers that decisions based on knowledge of ecosystems are more enduring and cost effective than decisions derived from uninformed consensus. It also provides scientists with models for designing research to meet threats to our most precious natural resources. "If we can learn to save the parks," observe Halvorson and Davis, "perhaps we can learn to save the world."
