Polar bears may be adapting to survive warmer climates, says study

New research reveals a link between rising temperatures and changes in polar bear DNA, which may be helping them adapt and survive in increasingly challenging environments.  The study by scientists at the University of East Anglia (UEA) discovered that some genes related to heat-stress, aging and metabolism are behaving differently in polar bears living in southeastern Greenland, suggesting […]

UAF study links beaver expansion to faster Arctic thaw

The climate-driven spread of beaver ponds in Alaska’s Arctic accelerates the effects of a warming environment by causing pond-adjacent permafrost to thaw and by increasing the amount of liquid water present during winter. Those are the key findings of the first comprehensive, on-the-ground assessment of the northward migration of beavers. The research was led by […]
