- Abstract
Keywords: bioturbation; dietary change; ecosystem engineer; feeding habit; novel species interaction; omnivory; social learning; Ursus arctos The proportion of cicada nymphs was estimated at 14.3%, suggesting that brown bears consume cicada nymphs at a certain rate in summer. These data indicate that brown bears can most efficiently forage on cicada nymphs by searching intensively in the larch plantation where the nymphs aggregate at high density.
