Book Description
The investigation of the interactions between human and physical systems poses unique conceptual, methodological, and practical challenges. This book establishes a spatial science framework for policymakers, social scientists, and environmental researchers as they explore and analyze complex problems. The authors provide guidance for scientists, writers, and students across a broad range of fields on how to tackle discipline-specific issues of space, place, and scale as they propose and conduct research in the spatial sciences. This practical textbook and overview blends plenty of concrete examples of spatial research and case studies to familiarize readers with the research process, demystifying and illustrating how it is actually done. The appendix contains both completed and in-progress proposals for MA and PhD theses and dissertations, as well as successful research grants. By emphasizing research as a learning and experiential process, while providing students with the encouragement and skills needed for success in proposal writing, "Research Design and Proposal Writing in Spatial Science" can serve as a textbook for research-design or project-based courses at the upper-division undergraduate and graduate level.

Book Description
Bears have fascinated people since ancient times. The relationship between bears and humans dates back thousands of years, during which time we have also competed with bears for shelter and food. In modern times, bears have come under pressure through encroachment on their habitats, climate change, and illegal trade in their body parts, including the Asian bear bile market. The IUCN lists six bears as vulnerable or endangered, and even the least concern species, such as the brown bear, are at risk of extirpation in certain countries. The poaching and international trade of these most threatened populations are prohibited, but still ongoing. Covering all bears species worldwide, this beautifully illustrated volume brings together the contributions of 200 international bear experts on the ecology, conservation status, and management of the Ursidae family. It reveals the fascinating long history of interactions between humans and bears and the threats affecting these charismatic species.

Book Description
Beauty, grace and power make the tiger one of the world's most loved animals, yet it is precisely these qualities that have been its downfall. Poaching for skins and body parts, loss of habitat and prey and conflicts between people and wild tigers have caused catastrophic declines in tiger numbers throughout their range. If wild tigers are to survive through the next century, we must act now. Riding the Tiger is a comprehensive, scientific and eminently readable account of the problems and possible solutions of securing a future for wild tigers. Lavishly illustrated in full colour, it is written by leading conservationists working throughout Asia. It is a vital information resource for tiger conservationists in the field, necessary reading for serious students of carnivore conservation and conservation biologists in general, and an accessible overview of tiger conservation for general readers.

Book Description
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.
