North America's three bear species black bears, grizzly bears and polar bears don't typically live in the same place. Male brown bears traveled across ice, or even swam, to the islands, then mated with female polar bears and ensuing generations of hybrids until all noticeable traits of polar bears were bred out. Amidst much controversy, the bear has since been returned to Martell. These rare animals are found in the Arctic regions of northern Canada and Greenland, where they have adapted to life in the harsh, cold environments of the far north. Polar bears typically rely on sea ice to hunt for seals, which make up the vast majority of their diet. The pizzly bear is a polar bear-grizzly bear hybrid. It was during that year that it was spotted in the wild. And with that growing contact between the two species comes more mating, and therefore increased sightings of their hybrid offspring. According to DeSantis, generalist animals such as coyotes and cougars are the best survivors of rapid change to their environment, not highly specialized apex predators like polar bears and saber-toothed cats. (Getty) As climate change continues to threaten the habitat of the polar bear, the . Wildlife officials from Canada also have another name for this hybrid bear. Over the last decade, grizzly bear - polar bear hybrids have been confirmed within this region, triggering extensive discussion and speculation regarding the impact of hybridization on the parent species. What do these strange Pizzly Bear hybrids look like? During one of the last rapid climate warming periods, scientists think thats just what happened in Southeast Alaska. All of this could result in a habitat ready for the hybrids to move in and take over, leading to a loss in biodiversity if polar bears are replaced. [25], Such studies have not been limited to polar bears and brown bears, and it now appears that gene flow between species has been widespread during the evolution of the living species of bears. The feet of the pizzly bear is extensive, having more familiarity with brown bears, and the claws are long, unlike polar bears.

They are also known as grolar bears, another combination of their parents names. This expansion in territory has also changed what these grizzles are eating. However, on the other hand, some argue that these hybrid animals may be harmful to species because they arent true representatives of either, creating new problems regarding genetic diversity between species. According to one hybrid naming convention, the offspring of a male polar bear and a female grizzly is a pizzly bear; while the offspring of a male grizzly and female polar is a grolar bear. They are well adapted to life in the Arctic, with thick fur and a layer of fat to insulate them from the cold.

"We've known about pizzlies for quite some time, but their occurrence may be more common with ongoing Arctic warming," DeSantis said. A number of other bears that look like hybrids have been sighted, but without a DNA sample theres no way to verify for sure. This precipitous fall is linked partly to the encroachment of grizzly bears into polar bear ranges, where they outcompete them for alternative food sources, but also to polar bears' highly specialised diets, as DeSantis highlights in research published on April 1 in the journal Global Change Biology.

The names Pizzly and Grolar are composed of the English species names "Polar bear" and "Grizzly" depending on whether the father is a polar bear or a grizzly: Pizzly if the father is a polar bear, and Grolar if the father is a grizzly.

Male grizzlies begin emerging from their dens in April, but it would be unlikely for one to contact a female polar bear in estrus unless one ventured far out on the sea ice. Other scientists suggested putting the sires name first (as they do for many other hybrid animals). The cubs were covered with brown fur and looked much more like brown bears than polar bears. They also have a highly specialized, meat-only diet. Moose, Salmon, Giant Pandas, and even Monarch Butterflies are all great examples of how climate change is affecting animals, too.

According to DeSantis, grizzly bears are moving further north as temperatures rise. At the Smithsonian National Zoo in Washington, DC, a male polar bear and a female grizzly bear got together and mated at the zoo.

Earlier this summer, reports surfaced that a pizzly was shot by a Candian hunter. Scientists say that climate change is driving the hybridization. So, in that case, we would call a hybrid grizzly-polar bear one of two names: Over the past several years more of these grizzly-bear hybrids have been popping up in the wild. Scientists at the time said that the only thing that made it special was that it existed. A pizzly was first discovered in the wild in 2006, when a hunter in Canada's far north killed a bear with white fur and brown patches as well as the humped back and long claws characteristic of a grizzly bear. They are also known as grolar bears, another combination of their parents' names. Shidelers studies revealed that North Slope male grizzlies have a home range, if you could even call it that, of well over 1,000 square miles. Now, I wish we hadnt been such chickens and had gotten closer, Luke says. It is believed that a single hybrid (F1) female is the mother of all four of these backcross individuals. Either way, its a stark reminder that battling climate change isnt just about saving the human species. Most often, polar bears show up in August and remain through October, when the sea ice forms and gives them a platform to hunt seals.

"And then the claws are often longer than polar bear claws because grizzly bears have much longer claws, and in general the fur is a little bit darker than a polar bear."
