Possible Use Of Foresight, Understanding, And Planning By Wolves Hunting Muskoxen, L. David Mech
Possible Use Of Foresight, Understanding, And Planning By Wolves Hunting Muskoxen, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
On Ellesmere Island in 2006, arctic wolves (Canis lupus arctos) were observed making a two-pronged approach to a herd of muskoxen (Ovibos moschatus) and, on another occasion, ambushing muskoxen. Both observations seemed to provide evidence that the wolves were using foresight, understanding, and planning. Although the possible use of insight and purposiveness has been documented in captive wolves, the present report is one of the few to document the possibility that freeranging wolves use these other three mental processes.

Annual Arctic Wolf Pack Size Related To Arctic Hare Numbers, L. David Mech
Annual Arctic Wolf Pack Size Related To Arctic Hare Numbers, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
During the summers of 2000 through 2006, I counted arctic wolf (Canis lupus arctos) pups and adults in a pack, arctic hares (Lepus arcticus) along a 9 km index route in the area, and muskoxen (Ovibos moschatus) in a 250 km2 part of the area near Eureka (80° N, 86° W), Ellesmere Island, Nunavut, Canada. Adult wolf numbers did not correlate with muskox numbers, but they were positively related (r2 = 0.89; p < 0.01) to an arctic hare index. This is the first report relating wolf numbers to non-ungulate prey.
