A hybrid of a polar and brown bear may appear in the north of Yakutia due to changes in the habitat of mammals. On Monday, November 7, Director of the Institute for Biological Problems of Permafrost of the Siberian Branch of the Russian Academy of Sciences Innokenty Okhlopkov told about this.

How told scientist in an interview with TASS, in the lower reaches of the Kolyma River, where polar bears live, brown bears began to appear. In particular, cases of the appearance of brown bears were recorded in the Anabar region of the Republic of Sakha (Yakutia).

In this regard, it cannot be ruled out that a hybrid of polar and brown bears may appear in Russia. Such cases are already known to science: in Canada, animals were found, during the DNA analysis of the tissues of which it turned out that they are the result of crossing a polar bear and a grizzly bear.

Polar bears are classified as vulnerable species of animals and are included both in the Red Book of Russia and in the international Red Book. The Severtsov Institute for Ecology and Evolution Problems of the Russian Academy of Sciences said that rapid climate change and the resulting increase in temperature in the Arctic have significantly complicated the conditions for the existence of polar bears. Due to the reduction in the number of food sources for animals it became harder to survive.
