Wild caprinae, including sheep and goats, are an extremely valuable group of mammals. While most live in mountains, some inhabit desert grasslands, tropical forests or even arctic tundra. They range in size from the 30kg goral to the 350kg musk ox and display a variety of horn shapes and sizes as well as coat and body coloration. They are highly prized by hunters on account of their horns and their coats. Today, despite their important domestic relations, many wild caprinae are in danger of being lost forever: over 70 of caprinae taxa are threatened and over 30 endangered or critical. The main threats to them are over-harvesting, habitat loss and resource competition from livestock. Some face an additional threat from trophy hunters. Despite this, however, conservation legislation is either absent or, more often, poorly enforced. This action plan explores the value of caprinae to biodiversity, the threats facing the members of the species, and makes recommendations to reverse current trends. It also emphasizes the importance to carpinae conservation and survival of close collaboration among all parties involved in wildlife conservation including local peoples and hunting organizations, governments, scientists and academic institutions.

One of the greatest unmet challenges in conservation biology is the genetic management of fragmented populations of threatened animal and plant species. More than a million small, isolated, population fragments of threatened species are likely suffering inbreeding depression and loss of evolutionary potential, resulting in elevated extinction risks. Although these effects can often be reversed by re-establishing gene flow between population fragments, managers very rarely do this. On the contrary, genetic methods are used mainly to document genetic differentiation among populations, with most studies concluding that genetically differentiated populations should be managed separately, thereby isolating them yet further and dooming many to eventual extinction Many small population fragments are going extinct principally for genetic reasons. Although the rapidly advancing field of molecular genetics is continually providing new tools to measure the extent of population fragmentation and its genetic consequences, adequate guidance on how to use these data for effective conservation is still lacking. This accessible, authoritative text is aimed at senior undergraduate and graduate students interested in conservation biology, conservation genetics, and wildlife management. It will also be of particular relevance to conservation practitioners and natural resource managers, as well as a broader academic audience of conservation biologists and evolutionary ecologists.

In Outlandish, acclaimed travel writer Nick Hunt takes us across landscapes that should not be there, wildernesses found in Europe yet seemingly belonging to far-off continents: a patch of Arctic tundra in Scotland; the continent's largest surviving remnant of primeval forest in Poland and Belarus; Europe's only true desert in Spain; and the fathomless grassland steppes of Hungary. From snow-capped mountain range to dense green forest, desert ravines to threadbare, yellow open grassland, these anomalies transport us to faraway regions of the world. More like pockets of Africa, Asia, the Poles or North America, they make our own continent seem larger, stranger and more filled with secrets. Against the rapid climate breakdown of deserts, steppes and primeval jungles across the world, this book discovers the outlandish environments so much closer to home - along with their abundant wildlife: reindeer; bison; ibex; wolves and herds of wild horses. Blending sublime travel writing, nature writing and history - by way of Paleolithic cave art, reindeer nomads, desert wanderers, shamans, Slavic forest gods, European bison, Wild West fantasists, eco-activists, horseback archers, Big Grey Men and other unlikely spirits of place - these desolate and rich environments show us that the strange has always been near.

"In North America there is one large animal that belongs almost entirely to the realm of towering rock and unmelting snow. Pressing hard against the upper limit of life's possibilities, it exists higher and steeper throughout the year than any other big beast on the continent. It is possibly the best and most complete mountaineer that ever existed on any continent. Oreamnos americanus is its scientific name. Its common name is mountain goat." Resourceful, belligerent, and unbelievably sure-footed, the mountain goat is a white-coated survivor from the Ice Age. Oreamnos americanus shares its dizzying alpine world with elk, eagles, bighorn sheep, and grizzlies. This first full-length book on the mountain goat offers a superbly written portrait of its life, habits, and environment. Douglas H. Chadwick tracked mountain goat herds for seven years, and his observations are richly textured and replete with fascinating and dramatic details. We learn of the mountain goats' lives from birth to adulthood, their feeding habits, unique social behavior and courtship rituals, and their long history. Chadwick also makes clear the troubling and escalating impact of the modern world on the mountain goat's wilderness home. This Bison Books edition features a new introduction by the author.

The Chang Tang, the vast, remote Tibetan steppe, is one of the most forbidding places on earth. Yet this harsh land is home to a unique assemblage of large mammals, including Tibetan antelope, gazelle, argali sheep, wild ass, wild yak, wolves, snow leopards, and others. Since 1985, George B. Schaller and his Chinese and Tibetan co-workers have surveyed the flora and fauna of the Chang Tang. Their research provides the first detailed look at the natural history of one of the world's least known ecosystems.

This book offers a concise but comprehensive introduction to desert ecology and adopts a strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis in the book is on the organisms that dominate this harsh environment, although theoretical and experimental aspects are also discussed. In this updated second edition, there is a greater focus on the effects of climate change and some of its likely effects on deserts, seeing desertification as among the most serious results of climate change, leading ultimately to the increasing size of arid and semi-arid regions. The Biology of Deserts Second Edition includes a wide range of ecological and evolutionary issues including morphological and physiological adaptations of desert plants and animals, species interactions, the importance of predation and parasitism, food webs, biodiversity, and conservation. It features a balance of plant and animal (both invertebrate and vertebrate) examples, and also emphasizes topical applied issues such as desertification and invasive species. The book concludes by considering the positive aspects of desert conservation. This accessible textbook is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers working in the field of desert ecology.

In the tradition of Douglas Chadwick's best-selling adventure memoir, The Wolverine Way, Tracking Gobi Grizzlies creates a portrait of these rarest of bears' fight for survival in one of the toughest, most remote settings on Earth. He demonstrates why saving this endangered animal supports an entire ecosystem made up of hundreds of interconnected plants and animals, from desert roses to Asiatic lynx and wild double-humped camels, all adapting as best they can to the effects of climate change. A parable of environmental stewardship in a legendary realm.
