self-organization.Recent studies have established a relationship between the repertoire of signals used for communication and neocortex size of different species of primates and the topology of the social network formed by the interactions between individuals. Inspired by these results, we have developed...
Discerning the relationship between sociality and longevity would permit a deeper understanding of how animal life history evolved. Here, we perform a phylogenetic comparative analysis of ~1000 mammalian species on three states of social organization (so
However, the social organization of these two species could not be more different (Kummer 1967, Dunbar 1983). 然而,这两个物种的社会组织完全不同(Kummer 1967,Dunbar 1983)。In geladas, cohesion of OMUs is maintained by philopatric females, as each OMU is a female kin group and these kin ...

Access through your organization Section snippets Social stimuli as rewards There is little doubt that social stimuli can be potent reinforcers for primates. An early demonstration comes from Butler (1954), who showed that rhesus monkeys would push open a door in order to watch an interesting sc...
Why be social? And, why not be? What are the costs and benefits of sociality, and what types of sociality characterize nonhuman primates?
Social organization in common marmosets (Callithrix jacchus) appears to be based on a hierarchy of dominance, in which dominant females limit the reproductive functioning of subordinates. Reduced fertility was documented for captive but not for wild females. We investigated social dynamics and hormonal...
Uwe Jürgens' chapter ('Neural control of vocalization in non-human primates') reviews the effects of stimulation, neuro-anatomical, and lesion studies on primate vocalizations, and concludes with a suggestion for the hierarchical organization of neural control of vocalization. In 'Mechanisms ...
Primates display a remarkable diversity of types of social organization—a diversity that, according to the socioecological model of social evolution, is ultimately determined by ecological factors limiting female fitness and the number of matings limiting male fitness. The foremost ecological determinants...
We review evolutionary processes and mechanisms that gave rise to the diversity of primate social systems. We define social organization, social structure
