ABSTRACT. Two hundred and twelve wolves (Canis lupus labrudorius) shot by hunters in northern Quebec and Labrador during the winters of 1976-77 through 1983-84 were examined for various population parameters. An estimated annual adult survival rate of 55 % and a recruitment rate of 49 % suggest a po...

| Summary: | ABSTRACT. Two hundred and twelve wolves (Canis lupus labrudorius) shot by hunters in northern Quebec and Labrador during the winters of 1976-77 through 1983-84 were examined for various population parameters. An estimated annual adult survival rate of 55 % and a recruitment rate of 49 % suggest a population of moderate exploitation. The sex ratio did not differ significantly from 1:l. Fifty-five percent of yearling females were pregnant or in breeding condition. The average litter size for all females was 6.8. Internal fat deposits were greatest in young males and older females. Caribou (Rangifer tarandus caribou) was the most common food item found in stomachs. A sample of caribou killed by wolves in the winter showed a selection for older-aged caribou with fat deposits slightly below that of the general population. Key words: wolf, caribou, northern Quebec, Labrador, predation &SUMÉ. Un total de 212 loups (Canis lupus lobrudorius) W s par des chasseurs dans le nord du Qubbec et au Labrador au cours des hivers de 1976-77 jusqu’i 1983-84 furent examinbs a h d’btablir divers param2tres relatifs i la population. Un taux de survivance annuel de 55 % pour les adultes et un taux de recrutement de 49 % suggerent une exploitation modbnk. Le taux de diffbrenciation sexuelle ne s’bloignait guhre de 1: 1. Cinquante cinq pour cent des femelles âgks d’un an btaient enceintes ou en condition apte i la reproduction. La portk moyenne btait de 6.8. Les dbp6ts de graisse interne paraissaient en quantie maximale chez les jeunes maes et les vieilles femelles. Le caribou (Rangifer tarandus caribou) btait la nourriture la plus communbment trouvk dans les estomacs. Un bchantillonnage de caribous tubs par des loups durant l’hiver signala la sblection de caribous plus âgbs avec d s dbp6ts de gras quelque peu infbrieurs i ceux de la population gbnbrale.
