DOWNLOAD EBOOK"We conducted a large-scale, controlled experiment to study the responses of declining woodland caribou (Rangifer tarandus), moose (Alces alces), and Dall sheep (Ovis dalli) to a 5-year reduction in wolf (Canis lupus) numbers in the Aishihik area in the southwestern Yukon"--Page 1

DOWNLOAD EBOOKThe Yukon wolf is the largest race of Canis lupus in the world. There are 5,000 wolves in the territory. Wolves live in all Yukon mountain ranges hunting Dall's sheep and caribou in the high alpine. In the forested valleys they hunt moose, the ideal prey size for packs to handle. Regional wolf numbers depend on the number of moose in the area. Packs are territorial except in the far north where wolves migrate long distances to follow the Porcupine caribou herd year-round. --From book cover.

DOWNLOAD EBOOKThe presentation and representation of the environment occurs throughout academia and across all news media. The strict protocols of science often clash with environmental information available from sources that dwell on subjective aesthetic, emotional and personal sensitivities. This book challenge the reader, as student, teacher, researcher or policy maker, to reflect critically on the ways that environments are studied, interpreted, presented and represented, in education and public policy.

DOWNLOAD EBOOKThe George River caribou herd increased from 15,000 animals in 1958 to 700,000 in 1988 - the largest herd in the world at the time. The authors trace the fluctuations in this caribou population back to the 1700s, detail how the herd escaped extinction in the 1950s, and consider current environmental threats to its survival. In an examination of the life history and population biology of the herd, The Return of Caribou to Ungava offers a synthesis of the basic biological traits of the caribou, a new hypothesis about why they migrate, and a comparison to herd populations in North America, Scandinavia, and Russia. The authors conclude that the old maxim, "Nobody knows the way of the caribou," is no longer valid. Based on a study in which the caribou were tracked by satellite across Ungava, they find that caribou are able to navigate, even in unfamiliar habitats, and to return to their calving ground, movement that is central to the caribou's cyclical migration. The Return of Caribou to Ungava also examines whether the herd can adapt to global warming and other changing environmental realities.

DOWNLOAD EBOOKThe cougar is one of the most beautiful, enigmatic, and majestic animals in the Americas. Eliciting reverence for its grace and independent nature, it also triggers fear when it comes into contact with people, pets, and livestock or competes for hunters’ game. Mystery, myth, and misunderstanding surround this remarkable creature. The cougar’s range once extended from northern Canada to the tip of South America, and from the Pacific to the Atlantic, making it the most widespread animal in the western hemisphere. But overhunting and loss of habitat vastly reduced cougar numbers by the early twentieth century across much of its historical range, and today the cougar faces numerous threats as burgeoning human development encroaches on its remaining habitat. When Maurice Hornocker began the first long-term study of cougars in the Idaho wilderness in 1964, little was known about this large cat. Its secretive nature and rarity in the landscape made it difficult to study. But his groundbreaking research yielded major insights and was the prelude to further research on this controversial species. The capstone to Hornocker’s long career studying big cats, Cougar is a powerful and practical resource for scientists, conservationists, and anyone with an interest in large carnivores. He and conservationist Sharon Negri bring together the diverse perspectives of twenty-two distinguished scientists to provide the fullest account of the cougar’s ecology, behavior, and genetics, its role as a top predator, and its conservation needs. This compilation of recent findings, stunning photographs, and firsthand accounts of field research unravels the mysteries of this magnificent animal and emphasizes its importance in healthy ecosystem processes and in our lives.

DOWNLOAD EBOOKThis book assesses Alaskan wolf and bear management programs from scientific and economic perspectives. Relevant factors that should be taken into account when evaluating the utility of such programs are identified. The assessment includes a review of current scientific knowledge about the dynamics and management of large mammalian predator-prey relationships and human harvest of wildlife in northern ecosystems, and an evaluation of the extent to which existing research and management data allow prediction of the outcome of wolf management or control programs and grizzly bear management programs. Included is an evaluation of available economic studies and methodologies for estimating the costs and benefits of predator control programs in Alaska.

DOWNLOAD EBOOKWolves are some of the world's most charismatic and controversial animals, capturing the imaginations of their friends and foes alike. Highly intelligent and adaptable, they hunt and play together in close-knit packs, sometimes roaming over hundreds of square miles in search of food. Once teetering on the brink of extinction across much of the United States and Europe, wolves have made a tremendous comeback in recent years, thanks to legal protection, changing human attitudes, and efforts to reintroduce them to suitable habitats in North America. As wolf populations have rebounded, scientific studies of them have also flourished. But there hasn't been a systematic, comprehensive overview of wolf biology since 1970. In Wolves, many of the world's leading wolf experts provide state-of-the-art coverage of just about everything you could want to know about these fascinating creatures. Individual chapters cover wolf social ecology, behavior, communication, feeding habits and hunting techniques, population dynamics, physiology and pathology, molecular genetics, evolution and taxonomy, interactions with nonhuman animals such as bears and coyotes, reintroduction, interactions with humans, and conservation and recovery efforts. The book discusses both gray and red wolves in detail and includes information about wolves around the world, from the United States and Canada to Italy, Romania, Saudi Arabia, Israel, India, and Mongolia. Wolves is also extensively illustrated with black and white photos, line drawings, maps, and fifty color plates. Unrivalled in scope and comprehensiveness, Wolves will become the definitive resource on these extraordinary animals for scientists and amateurs alike. “An excellent compilation of current knowledge, with contributions from all the main players in wolf research. . . . It is designed for a wide readership, and certainly the language and style will appeal to both scientists and lucophiles alike. . . . This is an excellent summary of current knowledge and will remain the standard reference work for a long time to come.”—Stephen Harris, New Scientist “This is the place to find almost any fact you want about wolves.”—Stephen Mills, BBC Wildlife Magazine

DOWNLOAD EBOOKStrategies for protecting wolves, mountain lions, and more—by taking the human species into account as well: “Very valuable.”—Journal of Wildlife Management Drawing on six case studies of wolf, grizzly bear, and mountain lion conservation in habitats stretching from the Yukon to Arizona, Large Carnivore Conservation argues that conserving and coexisting with large carnivores is as much a problem of people and governance—of reconciling diverse and sometimes conflicting values, perspectives, and organizations, and of effective decision making in the public sphere—as it is a problem of animal ecology and behavior. By adopting an integrative approach, editors Susan G. Clark and Murray B. Rutherford seek to examine and understand the interrelated development of conservation science, law, and policy, as well as how these forces play out in courts, other public institutions, and the field. In combining real-world examples with discussions of conservation and policy theory, Large Carnivore Conservation not only explains how traditional management approaches have failed to meet the needs of all parties, but also highlights examples of innovative, successful strategies and provides practical recommendations for improving future conservation efforts. “Building on decades of work, this book integrates biological knowledge with human dimensions study and charts a course for coexistence with large carnivores.”—Douglas W. Smith, Senior Wildlife Biologist, Yellowstone National Park
