一群1只幼鱼的摄食行为。日本猴子Yakuzaru（M. F. 1976年3月至12月，在屋久岛观测了407 h，观测时间为3 mo。1975年的初步调查。该群体居住在一个成熟的暖温带森林中，密度超过30只动物/平方公里。从8月至10月采用5分钟扫描技术。1976年12月，以检测摄食行为的数量特征。这支部队的成员以76种植物为食：26种的叶子，45种的果实和12种的其他部分。日本夜叉是食果动物。食物选择的模式进行了讨论有关水果生产。这些动物吃落叶植物的叶子比吃万年青木本植物的叶子多得多。选择比，花在每个物种上的时间的百分比，每个物种在样本带的百分比丰度，计算来评估食物选择从植物群落。通过计算木本植物群落、所有木本植物食物种和所有主要木本植物食物种的相似性指数，将该亚种的食性与日本不同生境中的其他6个种群的食性进行了比较。
Feeding behavior in a troop of 1 ssp. of the Japanese monkey, the Yakuzaru (M. f. yakui), was observed for 407 h on Yakushima Island between March and Dec. 1976, after a 3 mo. 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 Aug.-Dec. 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 spp. 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 to evaluate food selection from the plant community. The food habits of this subspecies were compared with that of 6 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.
