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 km(2) part of the area near Eureka (80 degrees N, 86 degrees W), Ellesmere Island, Nunavut, Canada. Adult wolf numbers did not correlate with muskox numbers, but they were positively related (r(2)=0.89;p < 0.01) to an arctic hare index. This is the first report relating wolf numbers to non-ungulate prey
