摘要
In this paper, food habits of the wolf (Canis lupus) was determined in Inner Monolia, using scat analysis. Results indicated that ungulates were the staple food items(frequency 53.8%, relative biomass 85.2%). In the scats, animals was 40.3% by the frequency of occurrence, and 75.7% by the relative biomass. Compared with the food habits of wolves in Heilongjiang Province, wolves showed a different pattern in prey selection in this ergion. In this study, we estimated the relative biomass of food items, and amount of each prey ingested by a wolf, based on a linear regression equation, y=2.76+0.02x(r=0.997), which was obtained in the feeding trials, It is suggerted that wolves are opportunistic predator. Some suggestions for wolf conservation and management were disussed.
