Polar bears are spending more time on land as Arctic ice diminishes, causing them to lose body weight and decline in numbers as they are unable to hunt for favored prey such as seals. This question can be a good springboard for further exploration of how scientists study and report evidence of climate change.

In a new study published in Ecological Applications, Laidre and her colleagues described how declining sea ice concentrations are affecting the behavior, health, and reproductive success of polar bears. 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. First seen in the wild in 2006, this polar bear-grizzly hybrid is more resilient to climate change and better suited for warmer temperatures, according to paleontologist Larisa DeSantis of Tennessees Vanderbilt University. With global warming and sea-ice declines, it becomes harder for polar bears to hunt their preferred preyseals.

Polar bears, on the verge of extinction due to climate change, are frequently moving inland in search of food and mating with grizzly bears to create a hybrid animal that is more resilient to the warming world. Animals have been interbreeding for millennia. "Polar bears spend much of the winter on the ice and then when the ice goes out in the early summer, they tend to move onto land for a period of time, and then when the ice forms again in the fall, they go out on the ice again. Sea ice has been breaking up earlier in the spring over the years (green) and is forming later in the fall (blue). These experiments demonstrate a strong correlation between the ability to exert self-control in children and their later success as adults. 0000036276 00000 n b!YrJ;4%&h3x.>Q* o8a$1>;GyDD"R# zNRqAb1*4$$'gr`&FB`N;(0wk-0_"&1NHS]t-MM b%IHkgm_=d:PF>~2H9hf}f`g pUUnlA8Yoe+?gDipy%]lN9wjMa-v+: sQ: Grizzly bears in Alaska and Canada are moving north as their environment warms, bringing them into contact with polar bears located on the coastline. ), "Used this last week as a sub plan while I was gone, and it was a huge success!"

Sea and Lake Ice, Image of the Day This material may not be published, broadcast, rewritten, or redistributed. 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. In the meantime, Laidre hopes this studys information will be used to further understand the impacts of sea ice loss on the species. Using field observations and remote sensing, the study showed that polar bears are spending more time on land and are fasting for longer periods of time. 0000009276 00000 n Its a major cause of species extinctionlots of species are now disappearing because they are being genetically swamped by other, commoner ones, said Stuart Pimm, a professor of conservation ecology at Duke University. 2019 Arctic Sea Ice Minimum Is Second Lowest.

Rather than growing a new branch on the [genetic] tree, you have two branches growing together, he said. They projected that the normal cub litter size of two may decrease within the next three polar bear generations (37 years), mainly due to the projected decline of sea ice in the coming decades. Chris Servheen, a bear biologist and Adjunct Associate Research Professor at the University of Montana, said sightings of this hybrid bear species have been very rare in the past. Grizzly bears and polar bears only diverged 500,000 to 600,000 years ago, so the two species can mate and produce viable offspring. 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. The maps above show the difference in sea ice extent around Baffin Bay on July 15, 1993 and July 15, 2013. 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. Scientists believe the pizzly arose when polar bears migrated south due to shrinking arctic ice, where they met up with grizzlies and mated. The team tracked polar bear movements across the bay over the past two decades. Their findings show that the two bears split into distinct species around 1.5 million years ago, with the .
