Abstract
Feeding behavior in a troop of one subspecies of the Japanese monkey, the Yakuzaru (Macaca fuscata yakui), was observed for 407 hr on Yakushima Island between March and December 1976, after a three-month preliminary survey in 1975. The troop dwells in a mature warm temperate forest at a density of over 30 animals/km2. The 5-min scanning technique was employed from August to December 1976, to detect the quantitative features of feeding behavior. The members of this troop fed on 76 plant species: on the leaves of 26, the fruits of 45, and other parts of 12 species. The Yakuzaru is essentially frugivorous. The pattern of food selection is discussed in relation to fruit production. The animals fed much more on the leaves of deciduous than of evergreen woody plants. “Selection ratio” the percentage of time spent feeding on each species to the percentage abundance of each species in the sample strip, was calculated in order to evaluate food selection from the plant community. In addition, the food habits of this subspecies were compared with that of six other populations in various habitats in Japan, by computing the similarity index for the woody plant community, all woody plant food species, and all major woody plant food species.
