Detection of arboreal feeding signs by Asiatic black bears

Asiatic black bear (Ursus thibetanus) climbs the trees to eat fruits by breaking branches, and arboreal feeding signs (AFS) are formed in trees. We focused on hard mast tree and researched the influence of fruit quantity of individual trees and at regional scale on the detection of AFS to clarify in what case bears climb to eat fruit. Results suggested that bears may maximize their feeding efficiency by climbing more trees with higher energy values.
