How bears bulk up ahead of the summer: A study into the Asiatic black bear's spring diet

(Pensoft Publishers) Much like gym enthusiasts, every year Asiatic black bears seem to be on the lookout for protein-rich food ahead of the summer, so that they can bulk up on lean muscle mass in place of the fat tissue formed last year prior to hibernation. This was concluded in a study, based on direct observations on bears living across an area of about 60 km2 in Japan and published in the open access journal ZooKeys.
