Pygmy chimpanzee association patterns in ranging

Abstract

The spatial distribution and its change of a pygmy chimp population was studied. The association patterns of the population demonstrated the existence of a bisexual group whose members associate almost exclusively with one another. Further within the group there were cohesive subgroups consisting of both sexes. The bisexual subgroups were related to female clusters whose members share the smaller range than that of the group. Frequent associations among male and female pygmy chimps largely modified the general tendency that females use smaller areas than males. Social units common to two species of chimps are bisexual groups which give the outer frames for the formation of associations and also for the range use.
