Polar-Grizzly Bear Hybrids Now Found in the Wild

Polar-grizzly bear hybrids – also known as grolar bears – were once thought to be found only in zoos. Now they are being discovered in the wild.

On Banks Island in 2006, a strange creature was shot: a grolar bear. The DNA of the animal was tested by scientists, who discovered that the shot bear was the offspring of a polar bear and grizzly bear. In 2010, a second-generation hybrid was also found and shot in the wild of Canada’s Northwest Territories by David Kuptana.

Both of these events prove that polar-grizzly hybrids are not only surviving, but thriving in the wild. They are successfully passing on their genes to newer generations. Once believe to be reproducing solely in captivity, researchers are finding out that polar-grizzly hybrid bears are now being discovered beyond the containing walls of zoos.

So what does this mean? Why are these bears – usually so far from each other in their natural environments – interbreeding? According to National Geographic, researchers have concluded that each species is being forced into closer proximity with one another. Unfortunately, much of their natural habitat is lost is due to human intervention and impacts. On top of that, there are even some scientists who believe that global warming is to blame.

Marine biology of the International Arctic Research Center at the University of Alaska, Brendan Kelly, suggests that these polar-grizzly hybrids are, if anything, going to become a rather popular addition to the animal kingdom. This is primarily because of the melting sea ice, and without sea ice for them to hunt and live on, the polar bears will be forced further inland near grizzly bears, thus resulting in an increase of polar-grizzly hybrids.

In the end, there may be even more mixed creatures than just polar-grizzly hybrids. Kelly states: “We’re taking this continent-sized barrier to animal movement, and in a few generations, it’s going to disappear, at least in summer months. That’s going to give a lot of organisms-a lot of marine mammals in particular-who’ve been separated for at least 10,000 years the opportunity to interbreed again, and we’re predicting we’re going to see a lot of that.”

Along with other animals that may possibly interbreed, if Kelly is correct, then the near future is sure to find more polar-grizzly bear hybrids. That being said, if you ever find yourself in one of those rare and heart-pounding situations in which you spy a bear in the wild, you may be looking at a grolar bear if it has the following attributes: lengthy necks, broad shoulders and humps, oh and of course the combination of coarse polar and grizzly hairs. But, to be on the safe side, you may want to keep your hybrid tacking skills solely at the zoo.

Animal Shelter Closures Place Lost Pets at Risk

Cats are less likely than dogs to be returned to owners if lost.

Most lost cats are never returned to their owners.

The economic downtown has not spared our four legged friends. Several animal shelters throughout the United States shuttered their doors at the end of 2011 or are at risk of imminent closure, leaving many homeless and lost  pets literally out in the cold. The last hope for many cats and dogs, these non-profit animal organizations, such as the Kindred Spirit Animal Rescue in Ripley County, MO, cite the high cost of operations and lack of volunteers for the closings. As animal lovers, the news is disheartening. Less shelters mean that less deserving pets will be rescued or find homes in the coming year and many more may be left outside and vulnerable to being hit by cars or death by exposure. Yet as pet parents, another less obvious risk could ultimately harm our beloved pets. Without adequate shelters, what will happen to our furry friends if they are lost?

Animal shelters are often a first stop on the search when your cat or dog goes missing. Fortunately, most shelters regularly work hard reunite owners with their lost pets whenever possible. Shelter staff often rely on microchips or tattoos to reunify pets and owners. According to the ASPCA, animals with permanent markers are far more likely to be returned. However, once one local shelter has closed, remaining animal resources are bound to be overcrowded. This means fewer resources and less time will be available to care for and identify your pet and track you down if she is separated from you.

In fact, the lack of a well funded shelter for your lost pet can be downright deadly to your precious pooch or feline. At some overcrowded and under-funded animal shelters, such as California  facilities, owners are given only a few days to claim their pets before their pets risk being euthanized. A critical lack of staffing at some shelters also means that your pet may not easily be identified as owned by the shelter staff. Such is the case at the Miami-Dade Shelter which makes it clear that with its high volume of intake that the responsibility is on the owner, not the shelter to identify your lost pet. This trend will only continue as funding for animal care facilities decreases and shelters close, placing your pet at greater risk if she is ever lost.

As animal lovers and responsible pet owners, then, it is very important that we both support our local shelters and invest in micro-chipping or other ways to identify your pet, which is the fastes and easiest way to reunite owner with pet.

Many local shelters have an on-line wish list of items needed for their animal friends and donations of any form and any amount is welcome. If you cannot invest in pet care products or cash, consider volunteering at your local shelter. While you may end up cleaning cages or filing paperwork, your extra hands will allow the staff more time to care for homeless animals and help reunite lost pets.

Finally, if your pet is not micro-chipped or tattooed, ask your local ASPCA or veterinary service about the procedure. Micro-chipping is a safe, cost-effective way to help your pet find her way back home and ensure your lost pet does not end up in an overcrowded and understaffed animal shelter.
