Characteristics of Three Barren-ground Caribou Calving Grounds in the Northwest Territories


Book Description

To understand how and why caribou use certain areas for calving as well as the environmental characteristics of calving grounds, a literature review on the calving grounds of the Bathurst, Beverly and Kaminuriak herds as well as a brief sample of the vegetation of the Beverley calving grounds was conducted.







The Natural History of an Arctic Oil Field


Book Description

In spite of the harsh conditions that characterize the Arctic, it is a surprisingly fragile ecosystem. The exploration for oil in the Arctic over the past 30 years has had profound effects on the plants and animals that inhabit this frozen clime. The Natural History of an Arctic Oil Field synthesizes decades of research on these myriad impacts. Specialists with years of field experience have contributed to this volume to create the first widely available synopsis of the ecology and wildlife biology of animals and plants living in close association with an actively producing oil field. - First widely available synthesis of arctic oil field ecology and wildlife biology - Concise yet readable treatment of a diverse polar ecosystem - Useful for land managers, policy makers as well as ecologists, and population biologists - Chapters authored by recognized authorities and contributions are peer-reviewed for accuracy and scientific rigor - Illustrations attractively designed to enhance comprehension




Precalving Distribution and Abundance of Barren-ground Caribou on the Northeastern Mainland of the Northwest Territories


Book Description

Report of a study conducted to determine numbers and precalving distribution of barren-ground caribou (Rangifer tarandus groenlandicus) in northeastern Keewatin District, N.W.T. Three regions were found to coincide with calving grounds of previously defined herds, the Melville, Wager and Lorillard.







Return of Caribou to Ungava


Book Description

The 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.







Mortality of Migratory Barren-ground Caribou on the Calving Grounds of the Beverly Herd, Northwest Territories, 1981-83


Book Description

Results of an investigation of the mortality of migrating barren-ground caribou, Rangifer tarandus groenlandicus, on the calving grounds of the Beverly caribou herd, District of Keewatin, in 1981, 1982 and 1983.







Barren-ground Caribou of the Northwest Territories


Book Description

"This NWT wildlife sketch provides information on barren-ground caribou of the N.W.T. Distribution is described for the four subspecies of caribou: Woodland caribou, Peary caribou, Grant's caribou, and barren-ground caribou. This sketch provides information on the physical description, the behaviour, the life history, reproduction, and management of barren-ground caribou"--ASTIS database.
