Abstract
This paper con- cludes the Canadian Arctic Wild Life Enquiry which has been based on questionnaires sent out annually by the Northwest Territories Administration, Ottawa, and by the Hudson''s Bay Company, Winnipeg. Arctic foxes were mostly at a peak in 1933-34. Since then there have been three further peaks. These occurred in 1937-38, 1941-42, and 1945-46 in n. Quebec and other areas. Some regions were out of phase with the rest, but synchronous fluctuations occurred over vast areas of the eastern and western Arctic. Lemming peaks were reported for the same year as those of the fox or one year earlier. Snowy owl migrations coincided with the disappearance of the lemming populations of the Arctic. Sledge dogs suffered three pandemics. There was no obvious connection with periodic decrease of lemmings and arctic foxes.
