They discover a polar bear population adapted to survive without sea ice in Greenland



In southwestern Greenland, they found a group of polar bears that could adapt to hunting without sea ice. This suggests that some members of the species can survive despite the current Arctic situation and what comes when the ice warms.

Studies published in the journal ChemistryRevealed it The polar bear population in southwestern Greenland was able to adapt to the current climatic conditions of the Arctic Circle. .. This species requires sea ice to hunt seals, but this isolated group has found another way of feeding.

This polar bear population currently lives in an area of ​​Greenland where ice lasts only about 100 days of the year and is separated from the glacier for the rest of the time until it melts.

This study is “Sea ice in the region is shrinking due to global warming, and these animals are expected to be endangered by the end of this century. “.

But the bear in this place They found a way to feed without having to hunt the surface of large ice cubes. This is a population of 27 adult women and does not travel too far to get food.

How did polar bears adapt?

Study explains it When bears came out of a large fjord and hunted, their problem was that the ice shelves were not stable enough or they broke. .. Then I was swept away by the stream, but instead of being swept over the ice, I started swimming.

“”They get caught up in the stream that tears the coastline and actually jumps out.They landed and went home Christine Reidre, an animal ecologist at the University of Washington in Seattle and the lead author of the study, said.

But this was not the only discovery. investigating, They also found that these bears have been quarantined for 200 years and are genetically distinct from the larger groups in the Arctic Circle. .. They say this is because the area they live in is “surrounded by mountains and ice caps in the west and by the sea in the east.”

“The presence of this small population under low sea ice conditions suggests that the species may survive further north of the sea ice each year,” the article said. ..
