It is believed that a single hybrid (F1) female is the mother of all four of these backcross individuals. Grizzly bears are specially adapted to survive the changing seasons. But in Wapusk National Park, on the west coast of Hudson Bay in . Although these sister species often occupy adjacent regions, direct contact has not been the norm because polar bears hunt, breed, and sometimes even make maternity dens on sea ice, where brown bears have an overwhelmingly terrestrial lifestyle. I graduated from Brigham Young University with a masters degree in Comparative Studies, focusing on the relationship between humanity and the natural world. WATCH: Sharks biting alligators, the most epic lion battles, and MUCH more. And with that growing contact between the two species comes more mating, and therefore increased sightings of their hybrid offspring. Ursus maritimus the polar bearhints that this predator is as much at home hunting its prey in water as it is on the Arctic ice. Scientists have been unable to give an exact explanation for the phenomenon. . Results showed it to be 100 percent grizzly. She notes that grizzlies in the Arctic can be exceptionally light colored. Bears also come to feast on the remains of bowhead whales taken by Inupiaq hunters. Pizzly bears are known to be far less aggressive than either parent species alone and tend to lead solitary lifestyles. Samples were collected from all six, and genetic analysis confirmed both their hybrid status and their family relationships. Subscribe to OL+ for our best feature stories and photography. In June of 2019 Peter Flynn was on a 19-day trek across the Arctic National Wildlife Refuge (ANWR) when, 400 yards away, he and his companions saw a bear pouncing like a fox on ground squirrels. As global temperatures continue to rise, the two species of bear are slowly congregating together more and more.

This appears to reflect a process in which a population of polar bears was left behind as the species retreated northwards at the end of the last ice age, with male brown bears subsequently introducing genes from the adjacent mainland, but female brown bears being generally unable or unwilling to swim across several kilometres of open ocean to reach the islands (thus the lack of exchange of mitochondrial DNA). With several suspected sightings and eight confirmed cases,[3] theories of how such hybrids might naturally occur have become more than hypothetical.
