The Arctic has been live model to check out effects of climate change. Along with ice, the ecology of the region has been affected too. For the first time, researchers have spotted polar bears eating dolphins at the North Pole. The team of scientists from Norway is blaming the climate change for this. The sensitive ecology of the region has been compromised and as ice melts, the polar bears are forced to look for different food resources.
The expansion of diet by polar bear was the result of many factors. Norwegian Polar Institute's scientist captured polar bears hunting and eating dolphins on a camera. Traditionally, the seals have been the diet of these white creatures. The latest research published in the science journal informed the world about this development. The regions nearby the equator are warming rapidly due to climate change and therefore many creatures in the tropical and temperate zones are migrating to cooler areas at the North Pole.
These newly migrated species are now becoming targets of polar bear in hunting activities. In April last year, two polar bears were caught on camera while eating dolphins. Dolphins are pretty common in Arctic around Norway during summer, as there is less ice but now they can be observed in the colder period of winter and spring. The researchers reported two ice-free winters back to back and this may have attracted dolphins in this region. The polar bear in photograph has also stored another dolphin in the snow for the future diet.
