«We took the data from the American record-keeping system, based on tagging the animals on the ice of the Chukchi Sea on the Alaskan side of the sea. The Americans started this work 10 years ago; the animals were immobilised from the helicopter, then collars were put on them or their ears were tagged and then they were released. The research was repeated yearly,» Kochnev said.

The scientists also noted that the population in Chukotka and Alaska is in a better condition than the rest of the bears in the Arctic. The bears of this population are well fed, since there is a lot of food for them in the Chukchi Sea, and females of the Arctic predator give birth to more bear cubs.
