"The mortality of migratory barren-ground caribou (Rangifer tarandus groenlandicus) on the calving grounds of the Beverly caribou herd, District of Keewatin, Northwest Territories, was investigated in 1981,1982, and 1983. Two hundred and eighty-seven dead or incapacitated newborn caribou calves were found and necropsied between 31 May and 20 June 1981, 8 and 23 June 1982, and 6 and 17 June 1983. Wolf (Canis lupus) predation was the single most important cause of newborn calf mortality (68.5%), followed by atelectasis (fetal and neonatal) (14.2 %), pathophysiological disorders (6.7 % ), separation or abandonment (6.2 %), pneumonia (4.0 %), and grizzly bear (Ursus arctos) predation (0.4%)"--Abstract.
