Wolf winter predation on moose and roe deer in relation to pack size
Wolf (Canis lupus) winter predation on moose (Alces alces) and roe deer (Capreolus capreolus) were studied in the small, but fast growing wolf population on the Scandinavian Peninsula. Wolves in one territory were radio- and snow-tracked during two successive winters. The wolf pack consisted of an a...
