| Research Abstract |
Japanese macaques adjust their proximity to group members depending on several members within a close proximity (ca. 20m). They also adjust their proximity to group members staying farther away (> 40m), suggesting that they also know the approximate position of the whole group. We compared the group cohesiveness of “cohesive” group of Japanese macaques and “fission-fusion” group of spider monkeys. Distribution and temporal change of inter individual distance between the two individuals were similar between the two species, suggesting that basic mechanisms of group cohesion are similar between the two species.
