Why polar bears are killing, eating each other up


MOSCOW: Cases of polar bears killing and consuming every different are on the rise in the Arctic as melting ice and human process erode their habitat, a Russian scientist stated.

“Cases of cannibalism among polar bears are a longestablished fact, however such circumstances was found hardly while now they're recorded relatively ceaselessly,” stated polar endure professional Ilya Mordvintsev, quoted by means of Interfax information company. “We state that cannibalism in polar bears is increasing,” stated Mordvintsev, a researcher at Moscow’s Severtsov Institute of Problems of Ecology and Evolution.

Speaking at a presentation, he prompt that the behaviour could be because of lack of meals. “In some seasons there isn't enough meals and large males attack women folk with cubs,” he stated. The rise in circumstances can also be partly because of extra people operating in the Arctic and reporting such behaviour, he stated.

“Now we get data not handiest from scientists but in addition from the growing selection of oil workers and defence ministry staff.”

“The Gulf of Ob used to be all the time a hunting floor for the polar endure. Now it has damaged ice all yr spherical,” Mordvintsev stated, linking this to active gasoline extraction at the huge Yamal peninsula that borders the Gulf of Ob, and the launch of an Arctic LNG (liquefied herbal gasoline) plant.


Another Russian scientist, Vladimir Sokolov, who has led numerous expeditions by means of the Arctic and Antarctic Research Institute, based in Saint Petersburg, stated this yr polar bears had basically been suffering from abnormally heat climate on Spitsbergen Island to the west in Norway’s Svalbard archipelago, the place there were no ice floes and little snow.


Russian researchers have recorded growing numbers of polar bears moving away from their conventional hunting grounds as ice melts because of world warming. Over the closing quarter-century, Arctic ice levels by means of the end of summer time have fallen by means of 40%, stated Sokolov. He predicted that polar bears would sooner or later not hunt on sea ice and be confined to shore areas and high-latitude archipelagos.


Russians in Arctic settlements have sounded the alarm over bears coming into areas of human habitation to raid garbage for meals.
