Decline and Recovery of a High Arctic Wolf-Prey System

A long-existing system of wolves (Canis lupus), muskoxen (Ovibos moschatus), and arctic hares (Lepus arcticus) in a 2600 km2 area of Canada’s High Arctic (80 ˚ N latitude) began collapsing in 1997 because of unusual adverse summer weather but recovered to a level at which all three species were repr...

Description
Summary:A long-existing system of wolves (Canis lupus), muskoxen (Ovibos moschatus), and arctic hares (Lepus arcticus) in a 2600 km2 area of Canada’s High Arctic (80 ˚ N latitude) began collapsing in 1997 because of unusual adverse summer weather but recovered to a level at which all three species were reproducing by 2004. Recovery of wolf presence and reproduction appeared to be more dependent on muskox increase than on hare increase.
