Book excerpt: Ecological Dynamics on Yellowstone's Northern Range discusses the complex management challenges in Yellowstone National Park. Controversy over the National Park Service's approach of "natural regulation" has heightened in recent years because of changes in vegetation and other ecosystem components in Yellowstone's northern range. Natural regulation minimizes human impacts, including management intervention by the National Park Service, on the park ecosystem. Many have attributed these changes to increased size of elk and other ungulate herds. This report examines the evidence that increased ungulate populations are responsible for the changes in vegetation and that the changes represent a major and serious change in the Yellowstone ecosystem. According to the authors, any human intervention to protect species such as the aspen and those that depend on them should be prudently localized rather than ecosystem-wide. An ecosystem-wide approach, such as reducing ungulate populations, could be more disruptive. The report concludes that although dramatic ecological change does not appear to be imminent, approaches to dealing with potential human-caused changes in the ecosystem, including those related to climate change, should be considered now. The need for research and public education is also compelling.

Available in PDF, EPUB and Kindle. Book excerpt: "The beloved Yellowstone National Park underwent a management shift in 1969 that drastically altered its landscape. This book comes at a time when scientific results are sometimes withheld so that they do not challenge policy positions. The author charges that Yellowstone-supported research has produced a faulty ecological paradigm, whether consciously or not, in order to maintain status quo of the Park's "natural-regulation" policy." "Wagner's ecosystem model of the Park's northern range focuses on a low-elevation region of the Park where a large herd of Rocky Mountain elk winters. His study spans 132 years of ecological, hydrologic, archaeological, photographic, and historic evidence and synthesizes the herd's impact over time."--BOOK JACKET.

Download or read book The Environment and International History written by Scott Kaufman and published by Bloomsbury Publishing. This book was released on 2018-12-13 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of the history of international relations traditionally have focused on the decisions made by those at the highest levels of government. In more recent years, scholars have expanded their attention to cover economic, cultural, or social interactions among nations. What has remained largely ignored, however, is the impact of an increasingly-interdependent world upon the environment and, conversely, how environmental concerns have affected the ecology, social relationships, economics, and politics at national, regional, and global levels. The Environment and International History fills this gap, looking at the interrelationship between international politics and the environment. Using a transnational and interdisciplinary approach, this book examines how imperialism, war, and a divergence of interests between the developed and underdeveloped world all have had implications for plants, animals, and humans worldwide.

Download or read book Cognitive Movement Ecology written by Eliezer Gurarie and published by Frontiers Media SA. This book was released on 2024-02-09 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: At least since Darwin argued that the difference in cognitive abilities between animals and humans is one of degree and not of kind, the study of animal cognition has been an active and dynamic subfield of behavioral sciences. It has, however, been based almost entirely on experimental studies of animals in captivity and belongs - as a field - more snugly in the realm of Psychology (or Ethology), with relatively little application to understanding the behavior of animals in the wild. Movement Ecology, in contrast, is a more recent branch of Ecology devoted almost entirely to the analysis of animal movements in the wild. Technological developments allow for animals to be tracked in the wild in ever-increasing numbers, precision, and duration. Movement ecology has, to some extent, “chased the data”, reflecting the practical need to analyze and interpret those data. Much of the most important developments of recent decades are devoted to dealing with the trickier aspects of the statistical analysis of movement data - which in their multidimensionality, autocorrelation, gappiness and measurement error, and behavioral complexity pose no shortage of hairy statistical problems.
Download or read book A Review of the Use of Science and Adaptive Management in California s Draft Bay Delta Conservation Plan written by National Research Council and published by National Academies Press. This book was released on 2011-08-19 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The San Francisco Bay Delta Estuary is a large, complex estuarine ecosystem in California. It has been substantially altered by dikes, levees, channelization, pumps, human development, introduced species, dams on its tributary streams and contaminants. The Delta supplies water from the state's wetter northern regions to the drier southern regions and also serves as habitat for many species, some of which are threatened and endangered. The restoration of water exacerbated tensions over water allocation in recent years, and have led to various attempts to develop comprehensive plans to provide reliable water supplies and to protect the ecosystem. One of these plans is the Bay Delta Conservation Plan (BDCP). The report, A Review of the Use of Science and Adaptive Management in California's Draft Bay Delta Conservation Plan, determines that the plan is incomplete in a number of important areas and takes this opportunity to identify key scientific and structural gaps that, if addressed, could lead to a more successful and comprehensive final BDCP. The plan is missing the type of structure usually associated with current planning methods in which the goals and objectives are specified, alternative measure for achieving the objectives are introduced and analyzed, and a course of action in identified based on analytical optimization of economic, social, and environmental factors. Yet the panel underscores the importance of a credible and a robust BDCP in addressing the various water management problems that beset the Delta. A stronger, more complete, and more scientifically credible BDCP that effectively integrates and utilizes science could indeed pave the way toward the next generation of solutions to California's chronic water problems.
Download or read book Trophic Cascades written by John Terborgh and published by Island Press. This book was released on 2013-06-25 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world’s leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world’s major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.
Download or read book Mountains and Plains written by Dennis H. Knight and published by Yale University Press. This book was released on 2014-01-01 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many changessome discouraging, others hopefulhave occurred in the Rocky Mountain region since the first edition of this widely acclaimed book was published. Wildlife habitat has become more fragmented, once-abundant sage grouse are now scarce, and forest fires occur more frequently. At the same time, wolves have been successfully reintroduced, and new approaches to conservation have been adopted. For this updated and expanded Second Edition, the authors provide a highly readable synthesis of research undertaken in the past two decades and address two important questions: How can ecosystems be used so that future generations benefit from them as we have? How can we anticipate and adapt to climate changes while conserving biological diversity?
Download or read book The Ecology of Large Mammals in Central Yellowstone written by Robert A. Garrott and published by Academic Press. This book was released on 2008-11-25 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an authoritative work on the ecology of some of America's most iconic large mammals in a natural environment - and of the interplay between climate, landscape, and animals in the interior of the world's first and most famous national park.Central Yellowstone includes the range of one of the largest migratory populations of bison in North America as well as a unique elk herd that remains in the park year round. These populations live in a varied landscape with seasonal and often extreme patterns of climate and food abundance. The reintroduction of wolves into the park a decade ago resulted in scientific and public controversy about the effect of large predators on their prey, a debate closely examined in the book. Introductory chapters describe the geography, geology and vegetation of the ecosystem. The elk and bison are then introduced and their population ecology described both pre- and post– wolf introduction, enabling valuable insights into the demographic and behavioral consequences for their ungulate prey. Subsequent chapters describe the wildlife-human interactions and show how scientific research can inform the debate and policy issues surrounding winter recreation in Yellowstone. The book closes with a discussion of how this ecological knowledge can be used to educate the public, both about Yellowstone itself and about science, ecology and the environment in general. Yellowstone National Park exemplifies some of the currently most hotly debated and high-profile ecological, wildlife management, and environmental policy issues and this book will have broad appeal not only to academic ecologists, but also to natural resource students, managers, biologists, policy makers, administrators and the general public. - Unrivalled descriptions of ecological processes in a world famous ecosystem, based on information from 16 years of painstaking field work and collaborations among 66 scientists and technical experts and 15 graduate studies - Detailed studies of two charismatic North American herbivore species – elk and bison - Description of the restoration of wolves into central Yellowstone and their ecological interactions with their elk and bison prey - Illustrated with numerous evocative colour photographs and stunning maps

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.
