Map of the study region showing place names mentioned in the text and proportion of effort-years wolves were known to be present in 20 areas of east and north Greenland, 1978–1998.
Queen Elizabeth Islands region (QEI) divided into five major areas by apparent importance to arctic-island wolves.
The Arctic wolf (Canis lupus arctos), also known as the Melville Island wolf, is a subspecies of gray wolf native to the Canadian Arctic Archipelago, from Melville Island to Ellesmere Island. It is a medium-sized subspecies, distinguished from the northwestern wolf by its smaller size, its whiter coloration, its narrower braincase, and larger carnassials. Since 1930, there has been a progressive reduction in size in Arctic wolf skulls, which is likely the result of wolf-dog hybridization.
