Responses of woodland caribou ( Rangifer tarandus caribou ) to clear-cutting in east-central Newfoundland
Movements, sex and age structure, and habitat selection of adult woodland caribou (Rangifer tarandus caribou) were examined in relation to clear-cutting on summer range in east-central Newfoundland during 1987 – 1990. We obtained 2473 locations of 35 radio-collared caribou during at least two consec...
