Arctic Animal Ecology


Book Description

A large number of comprehensive publications has been devoted to the Antarctic, to its plant and animal life. It is therefore relatively easy to familiarize oneself with the current state of Antarctic research. Nothing comparable is available for the Arctic. The heterogeneity and richness of the northern polar regions seem to have discouraged any attempt at a synthethic approach. This book has evolved from an attempt to summarize the results of 15 years of ecological and physiological research work in the Arctic - mostly on Spitsbergen. The necessity of comparing our results and the ecological conditions of Spitsbergen with other arctic regions grew into a full-sized book on arctic animal ecology. It is not meant as an exhaustive survey ofthe relevant literature. Instead I have tried to show how closely the various fields of research are interwoven, how many questions can be solved if only notice is taken of fellow scientists and their results, and how much arctic animals have in common. This book would not have been possible without the helpfulness of many colleagues. Above all I should like to mention Professor Ronning and Professor Solem of Trondheim University (Norway), Professor Arnthor Gardasson of Reykjavik University (Iceland), Dr. NettIeship, Dr. Oliver and Dr. Ryder of Canada and Professor West of Fairbanks University (Alaska, USA).




Trends in the Population of Barren-ground Caribou of Mainland Canada Over the Last Two Decades


Book Description

"Aerial surveys by the Canadian Wildlife Service in 1967 and 1963 produced an estimate of 385,000 barren-ground caribou for the four major populations on mainland Canada. A direct comparison of this estimate to results of the 1955 aerial survey of the same populations suggests an increase of approximately 50 per cent during the 12 years between surveys"--Abstract.

The Barren Ground Caribou of Keewatin (Classic Reprint)


Book Description

Excerpt from The Barren Ground Caribou of Keewatin In a previous paper (1953) I have endeavored to express to various Officials and friends my Sincere appreciation Of their cour tesy and generosity in furthering the work Of the expedition; and I can scarcely forbear to repeat here the names of at least a few Of them: Dr. A. L. Washburn, at that time executive director Of the Arctic Institute Of North America; Mr. R. A. Gibson, deputy com missioner of the Administration Of the Northwest Territories; and Mr. G. W. Malaher, director Of the Game and Fisheries Branch, Manitoba. For the loan Of a motion-picture camera, which secured for me some extremely gratifying scenes Of the migrant hosts on the Barrens, I am greatly indebted to Mr. William C. Morrow. Dr. Ralph S. Palmer has kindly read, and made helpful comments upon, a preliminary draft Of the present report. Through the courtesy of the American Museum Of Natural History, the United States National Museum, and the United States Fish and Wildlife Service, I have been able to examine important comparative material in their collections. A grant from the National Science Foundation has enabled me to carry the investigation through to completion.
