We present data from 4 studies of radiomarked brown bears (Ursus arctos) in Alaska to evaluate the effects of hunting and differential removal of males on cub survival and litter size. In the Susitna area in southcentral Alaska, the proportion of males declined during a period of increasing hunting pressure (1980-96). Cub survivorship was higher in the heavily hunted Susitna population (0.67, n = 167 cubs) than in a nearby unhunted population in Denali National Park (0.34, n = 88 cubs). On the… CONTINUE READING
