摘要: We examined the dispersal patterns of radio-collared wolves (Canis lupus) from 21 packs in Superior National Forest, Minnesota, 1969 to 1989. A total 316 (542 wolf-years) were captured, radio-collared, and followed during years radio-tracking; 75 identified as dispersers. Both sexes dispersed equally. Of adults, yearlings, pups, 8, 75, 16%, respectively, dispersed. Most dispersers left when they 11–12 months old, only a few dispersing adults. Dispersal occurred mainly February–April October–November. Adults short distances into nearby territories, but yearlings pups both long distances. Yearling pup rates highest wolf population was increasing or decreasing low stable. had pairing denning success. Yearlings moderate success, that ...
