Selection of calving sites by Porcupine herd caribou
Characteristics of 305 calving sites used by 131 different radio-collared caribou (Rangifer tarandus) cows from the Porcupine herd in northeastern Alaska and the northern Yukon Territory were investigated between 1983 and 1990 to determine the factors influencing calving site selection. Cows selecte...
