With the substantial advances in the miniaturization of electronic components, wildlife biologists now routinely monitor the movements of free-ranging animals with radio-tracking devices. This book explicates the many analytical techniques and computer programs available to extract biological information from the radio tracking data.
Key Features:
* Presentation of software programs for solving specific problems
* Design of radio-tracking studies
* Mechanics of data collection
* Estimation of position by triangulation
* Graphic presentation of animal migration, dispersal, fidelity, and association
* Home range estimation, habitat utilization, and estimation of survival rates and population size

This book represents the results of a comprehensive study of the ecological processes of the central Yellowstone ecosystem carried out over the past 15 years by an integrated team of scientists and graduate students. It provides an authoritative work on the mechanisms underlying the spatial and temporal dynamics of large mammal predator-prey systems in natural ecosystems, and is directed to the scientific community, resource managers, policy makers and the interested public alike.
This area includes the range of one of the largest migratory populations of elk in North America and for the past century it has been at the heart of public debates over population regulation of large herbivores and ungulates and their impact on ecological processes. Since the reintroduction of wolves into the system a decade ago the scientific and public controversy has shifted to debates about the impacts of large predators on their ungulate prey and potential predator-induced trophic cascades.
A part of central Yellowstone comprises the range of the large (2000-3500) migratory bison herd that summers in the high-elevation valleys in east-central Yellowstone, and winters along the headwaters of the Madison River to the west. This unique and diverse area of the Park and the opportunity it presents for studying ecological processes in a large pristine landscape has previously been largely ignored until this study.
The Editors vision is to build an integrated and multidisciplinary research program dedicated to: (1) producing objective science with the goal of advancing our knowledge of the central Yellowstone ecosystem; (2) supporting sound natural resource management, and (3) communicating theirknowledge and discoveries to the visiting public to enhance their experience and enjoyment of the Park. They have developed a small and tight-knit team of scientists with complementary skills and expertise.
Although there is ever-increasing discussion within the ecological community on the need to develop long-term, integrated and interdisciplinary research programs examples of such programs are relatively rare. The proposed book, synthesizing numerous projects will have very broad appeal not only to academic ecologists, but also to natural resource managers, policy makers, biologists, and administrators.
* Unrivalled description of a classic and world famous ecosystem, involving information from a 15 year integrated and multidisciplinary study by numerous scientists.
* Detailed analysis and comparison of two charismatic North American herbivore species - Elk and Bison
* Detailed description of the reintroduction of wolves into Yellowstone Park - and their ecology and impact on the herbivores and ecosystem in general.
* A whole ecosystem view, putting the biology, ecology, management and human dimensions into context.
* Numerous colour photographs

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.
