Mountain Sheep of North America


Book Description

Mountain sheep epitomize wilderness for many people because they occupy some of the most inaccessible and rugged habitats known to man, from desert crags to alpine mountains. But of all hoofed mammals in North America, wild sheep present the greatest management problems to biologists. This book is a major reference on the natural history, ecology, and management of wild sheep in North America. Written by wildlife biologists who have devoted years of study to the animals, it covers Dall's and Stone's sheep and Rocky Mountain, California, and desert bighorn and examines a variety of factors pertinent to their life histories: habitat, diet, activity, social organization, reproduction, and population dynamics. Additional chapters consider distribution and abundance, adaptive strategies, and management guidelines. Discussions on diseases of wild sheep present a wealth of information that will be of particular use to wildlife biologists, including detailed clinical descriptions of conditions that threaten sheep populations, from pasteurellosis to capture myopathy. An appendix reviews the cytogenetics and genetics of wild sheep. North American wild sheep may face extinction in many areas unless critical questions concerning their management are answered soon. Prior to the publication of this book, there was no single reference available in which one could find such a synthesis of information. Mountain Sheep of North America provides that source and points toward the preservation of these magnificent wild creatures.




Hoofed Mammals of British Columbia


Book Description

Hoofed mammals (ungulates) are the most abundant large mammals in the world. They are also plentiful in British Columbia, which is home to nine wild native species: moose, elk, caribou, bison, mountain goat, two species of deer and two of sheep. There are also several introduced species. In Hoofed Mammals of British Columbia, David Shackleton presents a comprehensive summary of the most up-to-date information on these ungulates. In the well-illustrated introduction, he discusses their evolution and biology, survival adaptations, and social organization. He also covers conservation issues, tracking, and taxonomy. In the species accounts, he describes each species and subspecies and discusses their natural history: habitat, diet, behaviour, reproduction, life expectancy, and mortality factors, and predators. Each account includes a distribution map and data on taxonomy, recent population estimates, conservation status, and traditional aboriginal use. Excellent illustrations and two keys help identify each species by its external features or its skull. Hoofed Mammals of British Columbia is the third of six handbooks on the mammals of British Columbia, a Royal B.C. Museum project to update and expand the classic treatment by Ian McTaggart-Cowan and Charles Guiguet, The Mammals of British Columbia, last revised in 1965.
