The answer might soon be common knowledge, as climate change has pushed these two species of bears together. There are eight species of bear: the North American black bear, the Asiatic black bear, the brown bear, the giant panda, the polar bear, the sloth bear, the sun bear, and the. According to The New York Post, this new species of bear first came to the attention of scientists in 2006. The female Kodiak bear gave birth to two hybrid cubs. Since 2006, several confirmed and unconfirmed sightings of "pizzly bears" have been reported as climate change alters the habitat and habits of the two species. Meanwhile, "polar bears are increasingly having to search for other food sources, when hunting seals from sea ice becomes untenable," she said. Interestingly, a single female polar bear gave birth to all four of these F1 hybrids. In 2006, the occurrence of this hybrid in nature was confirmed by testing the DNA of a unique-looking bear that had been shot near Sachs Harbour, Northwest Territories, on Banks Island in the Canadian Arctic. 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). The International Union for Conservation of Nature (IUCN) lists them as vulnerable to extinction with climate change a key factor. By one convention,[29] the name of the sire comes first in such combinations: the offspring of a male polar bear and a female grizzly would be the suggested nanulak or a "pizzly bear", while the offspring of a male grizzly and a female polar bear would be a "grolar bear" or possibly an aknuk. Wild sightings of hybrid pizzly bears began in 2006, when a hunter shot what he thought was a polar bear in the Northwest Territories of the Canadian Arctic.

By Adam Pockross. "In the meantime, polar bears will increasingly have to look for other food sources if hunting seals on the sea ice becomes impossible," she said. As a result, interbreeding has become more common between the two, a stark reminder of how climate change affects animals, too. kodiak grizzly bears - grizzly bear stock pictures, royalty-free photos & images.

It's called a "pizzly" or "grolar" bear, and is so rare only a handful of sightings have been confirmed in the wild -- and no one can say for sure how many even exist. If the father is a polar bear and the mother a brown bear, the offspring would be called the pizzly bear. Since there are only a handful of officially confirmed pizzly bears in the wild, more research needs to be done to better understand unique hybrid animals. It is currently unknown why grizzly bears are being found in the habitat of polar bears. That represents the loss of an area about twice the size of California. The pizzly bear is an example of the hybridization of two different species and has caused controversy, primarily from a conservation standpoint. Although the polar bear and grizzly bear had mated in the Smithsonian National Zoo, it was thought unlikely to happen in the wild. Posted at 07:21h .

They have a dished face, short, rounded ears, and a large shoulder hump. Sadly, only one of Pokodiaks double-hybrid cubs survived. No one has been attacked by a pizzly bear, as far as records show; however, this is possibly due to the species low numbers. Robert Rockwell, an ecologist at the American Museum of Natural History in New York City, backs this up. Time will tell.. The three bears seemed to get along just fine, and no one thought that a brown bear and a polar bear could mate across species. The other four were 75 percent grizzly and 25 percent polar bear, the result of the original two grizzly fathers mating with one of the first generation hybrid offspring.

"We've known about pizzlies for quite some time, but their occurrence may be more common with ongoing Arctic warming," DeSantis said. He was looking for food, new territory . Grizzly/Polar bear cross. Grizzly bears are large and range in color from very light tan (almost white) to dark brown. They are both able to delay implantation. Polar bears typically rely on sea ice to hunt for seals, which make up the vast majority of their diet. 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.

As the offspring of two of the most fearsome bears in North America, the polar bear, and the grizzly bear, there can be no doubt that the pizzly bear could be dangerous. With several suspected sightings and eight confirmed cases,[3] theories of how such hybrids might naturally occur have become more than hypothetical. The other four wild hybrid bears were second-generation pizzly bears, which means that their DNA is 75% grizzly, and 25% polar bear.

With features that could give them an edge in warming northern habitats, some scientists speculate that the pizzlies, or "grolars", could be here to stay. Either way, its a stark reminder that battling climate change isnt just about saving the human species. Meanwhile, many grizzly bears are headed northward, seeking out cooler regions. Other scientists suggested putting the sires name first (as they do for many other hybrid animals). Unlike western Canada, there are no large offshore islands in Alaska. Since there are few hybrid pizzly bears seen in the wild so far, it is hard to know for sure what will happen in the future.
