Researchers hint this could be occurring since with the sea ice thinning, more polar bears are making their journey towards the south, looking for food, whereas with temperatures in the south rising, more grizzly bears are moving towards the north, looking for colder climates. This means that they are being filled with large quantities of environmental poisons, and that forms a threat to the polar bear's existence.

Create your free account or Sign in to continue. Polar bears have been around for a long time (first diverging from grizzlies 4-5 million years ago), surviving some very strong fluctuations of the environment, so its difficult to theorize how this could have happened without them "temporarily going extinct", but keeping their DNA within grizzly bears. Hybridization can increase genetic diversity in some cases, said Tallmon. As weve developed genomic methodologies, were finding that organisms are exchanging genes with other species, Arnold said. Members of theHeliconiusbutterfly genus in the Amazon breed with other species within the genus and have developed more distinctive colors in the process.

Evolutionary science demonstrates that Polar and Grizzly Bears are very closely related, mainly separated by color and location, though still considered separate species [4]. Scientists think climate change causing bears paths to cross The grizzly-polar bear hybrid has only been found a few times. Article #16 Parasites Create Zombie Snails. They found that most bears follow the seasonal growth and recession of sea ice to end up on Baffin Island in the fall, when sea ice is usually at its lowest extent.

It is information rich and written to engage even reluctant readers. Reported first by Thred, according to researchers, rising global temperatures has forced the two species to congregate together and this frequency has now risen considerably, resulting in more interbreeding. Pizzlies, at the end are a result of a massive climatic instability and this surely isnt the acceptable way to go ahead. This is causing them to spend more time together, only increasing their chances of interbreeding. Thats important because when the bears are on land, they do not hunt seals, said Laidre. Perhaps the most visible casualty of climate change, polar bears could be all but extinct by 2100. It's the climate change diet and scientists say it's not. We've received your submission.

In some cases, hybridization can lead to reduced genetic diversity in animals, according to David Tallmon, an associate professor of biology at the University of Alaska. With global warming and sea-ice declines, it becomes harder for polar bears to hunt their preferred preyseals. Pizzly or grolar bear: grizzly-polar hybrid is a new result of climate change Grizzly bears in Alaska and Canada are moving north as their environment warms, bringing them into contact. If the father was a grizzly bear then the offspring is informally known as a grolar. A new study shows that polar bears are spending less time on sea ice, leading them to fast longer, become thinner and have fewer cubs. ARTICLE SUMMARY: In this particular article, students will learn about how climate change is warming the Arctic and threatening the habitat of the polar bear. 7. So-called "pizzly" bears were first spotted in the wild in 2006. A threat to genetic diversity? How antibiotic resistance develops is also discussed.
