Grim news about polar bears having a hard time to endure in an altering world isn’t brand-new, however one little light flickers versus the dark. There’s a healthy population of the huge bears living along the coast and islands of the Chukchi Sea.
The Chukchi Sea in between Alaska and Russia hosts a group of about 3,000 polar bears, according to the very first official research study of the bear subpopulation there.
There are 19 acknowledged polar bear subpopulations, however it’s challenging to track the size of the groups due to their roaming way of life and remote areas. The International Union for Preservation of Nature, which keeps the Red List of Threatened Types, reports there are an approximated 26,000 to 31,000 polar bears in overall, so the Chukchi Sea group’s size puts it at the luxury for the recognized subpopulation numbers
The Chukchi Sea animals have healthy quantities of body fat and a great survival rate for cubs. A research study from early 2018 tracked 9 bears in the Beaufort Sea north of Alaska and discovered most of them lost body mass when they ought to have been loading on fat. The scientists traced the issue to the bears’ battles with searching in a location where sea ice is vanishing.
A group led by scientists from United States federal firms and the University of Washington tracked bears in the Chukchi Sea in between 2008 and2016 The group sedated bears to gather biological samples, tagged them and connected GPS transmitters to a few of the animals.
The gathered information powered a brand-new design developed to approximate population size, which can be challenging when you have big predators strolling over broad locations.
The Chukchi Sea is house to shallow waters, a healthy seal population and whale carcasses that provide the animals much required food sources at a time when
The loss of sea ice due to environment modification is impacting another United States polar bear group in the southern Beaufort Sea, nearby to Alaska and Canada. University of Washington polar science scientist Eric Regehr states those bears are revealing indications of tension as ice vanishes and limits their capability to hunt and type.
While a healthy population of polar bears is favorable news, it might not last.
” It does not suggest that bears in the Chukchi Sea will not be impacted by ice loss ultimately,” Regehr stated “Polar bears requirement ice to hunt seals, and the ice is forecasted to decrease till the underlying issue of environment modification is attended to.”
The scientists released the research study online Wednesday in the journal Scientific Reports
