SUMMER FOOD HABITS OF GRAY WOLVES IN THE BOREAL FOREST OF THE LAC JAQUES-CARTIER HIGHLANDS, QUÉBEC
As part of a larger study on the ecology of gray wolves (Canis lupis) of the Lac Jacques-Cartier highlands, Québec, the 1996-1997 summer diet of two wolf packs was determined by examining undigested animal remains in 1,621 scats (Malbaie pack: n = 1,371; Grands-Jardins pack: n = 250). Concern about...
