]It was reported that the iceuls in the North Pole region die much more polar bear puppy. [[T][4]
[ According to the report of a research conducted in the US, it was noted that the polar bears had to swim more to reach the fry with their mothers, which increases the mortality rate between the puppies that are not accustomed to long-distance swimming.
In the framework of theresearch, the GPS device was inserted 68 female polar bears were viewed through satellite for 6 years in order to detect the distances of the floating.
In this time, the puppies and the long distance of the 11 female polar bear lost their offspring during these faces, which was expressed that it represents a 45 percent death rate.
[On the other hand, long distances were 18 percent of the mortality rate between the offspring polar bears without having to swim with their mothers.
It was taken into account that 20 of the polar bears in the projection face a long distance of 50 times in 6 years, among these distances there is 685 kilometers and it takes about 13 days.
[The polar bears, which are not accustomed to living in the water from the east, are birthing and nourishing in the land or frosts.
The research done earlier about the crossroad shows that only polar bears have to swim hundreds of kilometers to reach iceuls or land, while researchers note that climate change has difficulty swimming longer distances to find the food and natural habitat of these animals, pulling down under the foot of the polar bears, "buzuls are forced to swim."
