Multi-scale foraging decisions made by woodland caribou (Rangifer tarandus caribou) in summer
Multi-scale selection patterns can be understood from two perspectives: one that sees coarse scale patterns as the summation of fine scale patterns and the other that sees it as a hierarchy produced from multiple contributory factors. Here I examine caribou selection of foraging locations across thr...
