Fission-fusion societyとは 意味・読み方・使い方

In primatology, a fission-fusion society is one in which the social group, e.g. bonobo collectives of 100-strong, sleep in one locality together, but forage in small groups going off in different directions during the day. This form of social organization occurs in several other species of primates, though usually less organised and less social than bonobos (e.g. chimpanzees, hamadryas, gelada baboons, spider monkeys, and humans), cetaceans such as bottlenose dolphins and fish such as guppies. These societies change frequently in their size and composition, making up a permanent social group called the 'parent group.' Permanent social networks consist of all individual members of a faunal community and often varies to track changes in their environment and based on individual animal dynamics.
