Available in PDF, EPUB and Kindle. Book excerpt: Ongoing oil sand development in the Athabasca oil sand area of north-east Alberta will soon expose the woodland caribou in that area to markedly increased human disturbance. This study was initiated to obtain information on current abundance & distribution of caribou within the area, and on other key elements of population dynamics that will be needed for management. The report describes the dynamics of the caribou population in the Birch Mountain area, as determined by field studies carried out from January 1976 to June 1978. Research methods included examination & radio tracking of radio collared animals and visual tracking of animals after snowfall. Results are presented with regard to caribou physical characteristics, population density & distribution, age composition, sex ratios, survival of calves & adults, seasonal movements & ranges, and habitat use.

Available in PDF, EPUB and Kindle. Book excerpt: 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 The authors conclude that the old maxim, "Nobody knows the way of the caribou," is no longer valid.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.

Available in PDF, EPUB and Kindle. Book excerpt: This 1980 book considers the patterns of population fluctuations of animals and intraspecific social relations by means of comparative methods and discusses the evolution of population regulation mechanisms and social relations. The author proposes that parental care has evolved in environments in which it is difficult for the young to obtain food, whilst high fecundity has evolved in the opposite environment. He presents evidence from a wide range of organisms to argue that during evolution animals repeatedly face the 'choice' of two strategies - low fecundity combined with parental protection, or high fecundity - and that this choice determined the amplitude, regularity and associated main factors of population fluctuations as well as the main characteristics of social relations as expressed in group life or dispersed living involving territory. Although many examples are drawn from insects, with which the author is most familiar, mammal, birds and other animal groups are also examined in depth.
Download or read book Caribou and the North written by Monte Hummel and published by Dundurn. This book was released on 2008-08-18 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: "If the caribou die, then we die." These few words speak eloquently to the significanceof caribou for northern peoples. They were spoken not by a wise old chief, but by a 13-year-old Dene youth in 2007 during a hearing regarding uranium exploration on the caribou wintering grounds. Right now there is urgent, widespread concern about the future of the most centralof species: caribou. Caribou and the North brings both the facts and the feelingsof the current situation to a North American readership. The writers look at why we need to conserve the caribou, the threats that have faced caribou in the past, present, and future, and the actions that we can take. Also included is an appendixwith up-to-date information on the range, movements, habitats, numbers, population trends, and key threats to caribou in North America.
