摘要

Japanese macaques on Shodoshima Island habitually form very large rest clusters, in which 50+ or even 100+ individuals huddle together. This behavior is not seen in any other populations of the species. Mean cluster sizes of two groups of Shodoshima monkeys are three and four in summer and 17 and 16 in winter, respectively. A maximum of 137 individuals have been seen to huddle in one cluster. It is difficult to explain the extra large clusters on Shodoshima only as an adaptive behavior against cold, since Shodoshima is relatively warm in the range of habitats for Japanese macaques. Compared with other groups of Japanese macaques, Shodoshima monkeys show: more frequent affinitive interactions, shorter inter-individual distance, more frequent ignoring of exclusion, more frequent aggression, less intense aggression, and more frequent counter-aggression. These characteristics suggest that the Japanese macaques on Shodoshima have relaxed dominant relations. The specific social organization of Shodoshima monkeys may sustain the formation of extra large clusters. Inter-group comparisons suggest that the social structure of Japanese macaques might be highly plastic, and that Shodoshima monkeys have less despotic, more tolerant social relations than typically reported for this species.
