A PROVISIONAL LIFE TABLE FOR THE BARREN GROUND CARIBOU
A provisional life table for the continental Barren Ground caribou, Rangifer arcticus arcticus (Richardson), has been prepared from a collection of 292 mandibles collected in 1948 and 1949 on the summer and winter ranges of the species in northern Canada. The data include both sexes. The age of the...
