Book excerpt: The first Wild Trout Symposium (1974) was sponsored by Trout Unlimited and the United States Department of the Interior. The second Symposium (1979) added the Federation of Fly Fisherman as a sponsor. Five years later (1984) the U.S. Department of Agriculture - Forest Service joined. In 1989 , the U.S. Environmental Protection Agency and the American Fisheries Society joined. These symposia began with a concentration on management, then recognized that more than 'management' was required in ongoing efforts to enhance wild salmonid fisheries. Subsequent symposia began to examine a broader range of environmental and social factors influencing wild salmonids. The originators hoped that each symposium would be a building block upon which the succeeding symposium could provide insights and research which future sessions could revisit. Along with the broadening of sponsorship, we have grown , we have gained recognition, and we look forward to expanding our contribution to the cause of wild salmonids. We hope these Proceedings will stimulate readers thinking and efforts on behalf of our wild salmonid resources , and plan to participate with us in Wild Trout V.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to systematize and discuss population genetic studies of freshwater fish in a region that harbors the greatest diversity of species among all inland water ecosystems. This volume explores the genetic evaluation for a number of orders, families and species of Neotropical fishes, and provides an overview on genetic resources and diversity and their relationships with fish domestication, breeding, and food production.

Download or read book Battle Against Extinction written by W. L. Minckley and published by . This book was released on 1991-12 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1962 the Green River was poisoned and its native fishes killed so that the new Flaming Gorge Reservoir could be stocked with non-native game fishes for sportsmen. This incident was representative of water management in the West, where dams and other projects have been built to serve human needs without consideration for the effects of water diversion or depletion on the ecosystem. Indeed, it took a Supreme Court decision in 1976 to save Devils Hole pupfish from habitat destruction at the hands of developers. Nearly a third of the native fish fauna of North America lives in the arid West; this book traces their decline toward extinction as a result of human interference and the threat to their genetic diversity posed by decreases in their populations. What can be done to slow or end this tragedy? As the most comprehensive treatment ever attempted on the subject, Battle Against Extinction shows how conservation efforts have been or can be used to reverse these trends. In covering fishes in arid lands west of the Mississippi Valley, the contributors provide a species-by-species appraisal of their status and potential for recovery, bringing together in one volume nearly all of the scattered literature on western fishes to produce a monumental work in conservation biology. They also ponder ethical considerations related to the issue, ask why conservation efforts have not proceeded at a proper pace, and suggest how native fish protection relates to other aspects of biodiversity planetwide. Their insights will allow scientific and public agencies to evaluate future management of these animal populations and will offer additional guidance for those active in water rights and conservation biology. First published in 1991, Battle Against Extinction is now back in print and available as an open-access e-book thanks to the Desert Fishes Council.

Download or read book The Great Smokies written by Daniel S. Pierce and published by Univ. of Tennessee Press. This book was released on 2000 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seeking a taste of unspoiled wilderness, more than eight million people visit the Great Smoky Mountains National Park each year. Yet few probably realize what makes the park unusual: it was the result of efforts to reclaim wilderness rather than to protect undeveloped land. The Smokies have, in fact, been a human habitat for 8,000 years, and that contact has molded the landscape as surely as natural forces have. In this book, Daniel S. Pierce examines land use in the Smokies over the centuries, describing the pageant of peoples who have inhabited these mountains and then focusing on the twentieth-century movement to create a national park. Drawing on previously unexplored archival materials, Pierce presents the most balanced account available of the development of the park. He tells how park supporters set about raising money to buy the land--often from resistant timber companies--and describes the fierce infighting between wilderness advocates and tourism boosters over the shape the park would take. He also discloses the unfortunate human cost of the park's creation: the displacement of the area's inhabitants. Pierce is especially insightful regarding the often-neglected history of the park since 1945. He looks at the problems caused by roadbuilding, tree blight, and air pollution that becomes trapped in the mountains' natural haze. He also provides astute assessments of the Cades Cove restoration, the Fontana Lake road construction, and other recent developments involving the park. Full of outstanding photographs and boasting a breadth of coverage unmatched in other books of its kind, The Great Smokies will help visitors better appreciate the wilderness experience they have sought. Pierce's account makes us more aware of humanity's long interaction with the land while capturing the spirit of those idealistic environmentalists who realized their vision to protect it. The Author: Daniel S. Pierce teaches in the department of history and the humanities program at the University of North Carolina, Asheville, and is a contributor to The Tennessee Encyclopedia of History and Culture.

Download or read book Ecology written by Michael Begon and published by John Wiley & Sons. This book was released on 2020-11-17 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: A definitive guide to the depth and breadth of the ecological sciences, revised and updated The revised and updated fifth edition of Ecology: From Individuals to Ecosystems – now in full colour – offers students and practitioners a review of the ecological sciences. The previous editions of this book earned the authors the prestigious ‘Exceptional Life-time Achievement Award’ of the British Ecological Society – the aim for the fifth edition is not only to maintain standards but indeed to enhance its coverage of Ecology. In the first edition, 34 years ago, it seemed acceptable for ecologists to hold a comfortable, objective, not to say aloof position, from which the ecological communities around us were simply material for which we sought a scientific understanding. Now, we must accept the immediacy of the many environmental problems that threaten us and the responsibility of ecologists to play their full part in addressing these problems. This fifth edition addresses this challenge, with several chapters devoted entirely to applied topics, and examples of how ecological principles have been applied to problems facing us highlighted throughout the remaining nineteen chapters. Nonetheless, the authors remain wedded to the belief that environmental action can only ever be as sound as the ecological principles on which it is based. Hence, while trying harder than ever to help improve preparedness for addressing the environmental problems of the years ahead, the book remains, in its essence, an exposition of the science of ecology. This new edition incorporates the results from more than a thousand recent studies into a fully up-to-date text. Written for students of ecology, researchers and practitioners, the fifth edition of Ecology: From Individuals to Ecosystems is anessential reference to all aspects of ecology and addresses environmental problems of the future.
