A young male American black bear, captured in south-central Alaska as a nuisance animal, is shown having been just placed in an artificial den. The bear is part of the hibernation research conducted by Øivind Tøien, research scientist with the Institute of Arctic Biology at the University of Alaska Fairbanks, and first author of an upcoming paper in Science on bear hibernation, and Brian M. Barnes, senior author on the same paper and IAB director.
