It is that time of the year when polar bears tend to spend less of their time fishing and swimming in the ocean, but rather go and check out what happened on the land in the meantime. Researchers have tracked the polar animals and observed that they tend to try some of the food on the shore as well, even if it is not as tasty as the fish of the deep oceans. So polar bears have been spotted looking for nests where birds use to lay eggs and eating the eggs they would find. Also, the animals polar bears find on land seem not so displeasing for the giant predators, so they are a source of food as well. Moreover, polar bears would sometimes try a bit of green cuisine, eating some of the plants they find on land.
Scientists have asked themselves if, given the fact that polar bears would eat something else than fish if needed, the creatures would survive in a land that is low on ice. Washington State University scientist, experts from the United States Geological Survey and officials representing the Polar Bears International have worked together in order to bring a new study on polar bears to the attention of academic environments.
The study they have accomplished is concerned with the nutrition of the polar bears, the way their metabolism works and also how ecosystems on land could provide a reasonable source of food for the white creatures. The experts did not find positive results. The study they have elaborated reveals the fact that ecosystems on shore won`t stand as a proper food resource for the polar bears, especially because the white bears are depending on a great amount of fat in their food. The experts have also added that the food which can be found in the land ecosystems is not available for the polar bears mainly. Their cousins, the Arctic grizzly bears already have their paws on that.
“Centered examination will help us figure out if physical nourishments could add to polar manage nourishment in spite of the physiological and wholesome confinements and the low accessibility of most physical sustenance assets. Then again, the confirmation up to this point proposes that expanded utilization of physical nourishments by polar bears is unrealistic to balance decreases in body condition and survival coming about because of ocean ice misfortune,”
said Dr. Karyn Rode of the U.S. Geological Survey, one of the leaders of the study.
