Abstract :

Wolf predation of beaver is common in boreal ecosystems, but predation events are thought to be rare in winter. We describe the encounter of a recent wolf predation event of a beaver during conditions of ice cover. The beaver bad a broken upper incisor, which may have contributed to it foraging on land during the winter. While it is common for injured animals to bate increased vulnerability to predation, injuries can also influence foraging decisions that may indirectly increase vulnerability to predation.
