Farther north, in the treeless expanses of northern Canada and Greenland, polar bear interactions present occasional fatalities for Arctic wolves (Canis lupus arctos). While polar bears focus primarily on marine mammals like ringed seals, melting sea ice pushes hungry white bears inland during the summer months. An adult polar bear, reaching weights of over 1,000 pounds, will displace wolves from muskox carcasses without hesitation. Mortalities occur when starving Arctic wolves push their scavenging efforts too close to a defensive bear.

Even without large carnivore pressure, Canis lupus natural causes limit wolf lifespans in the wild to an average of just 6 to 8 years, compared to 13 to 15 years in captivity. The constant physical toll of bringing down moose, elk, and bison leads to compound fractures, punctured lungs, and broken jaws. A crippled wolf cannot keep pace with the pack. Left behind, an injured canid quickly succumbs to starvation or falls prey to opportunistic predators that would never challenge a healthy animal.
