Societies characterized by fission–fusion dynamics consist of subgroups that frequently change in size and composition. Although this flexible lifestyle permits individuals to reduce conflicts of interest, it simultaneously imposes a unique set of challenges on group members that are regularly subject to prolonged separation. Theory predicts animals should evolve ritualized and risky displays to quickly update relationships at reunions. Here we investigated the function of nonconciliatory… Expand

Herd composition, kinship and fission–fusion social dynamics among wild giraffe
TLDR
It is suggested that giraffe herds share many characteristics of fission–fusion social systems and propose that sophisticated communication systems are a crucial component regulating subgroup dynamics. Expand
Collective movements, leadership and consensus costs at reunions in spotted hyaenas
Because collective movements have fitness consequences for all participants, group travel can impose conflicts of interest when group-mates vary. Challenges associated with coordinating activities ofExpand
Greetings in male Guinea baboons and the function of rituals in complex social groups.
TLDR
Greetings in Guinea baboons appear to signal commitment among party members, test relationships among spatially tolerant partners, and accentuate relationship strength among highly affiliated males, specifically to strengthen in-group affiliation and promote cooperation. Expand
On the evolution of baboon greeting rituals
TLDR
The form and function of male–male ritualized greetings and their relation to the various social systems present in the genus Papio are reviewed, shedding light on the evolution of ritualized behaviour in non-human primates and rituals in humans. Expand
The function of greetings in male Tonkean macaques
TLDR
Greeting frequencies were negatively correlated to the frequency of supplantations and conflicts, and they were not significantly influenced by age and dominance status, showing that greetings are not used to appease partners or decrease tension between males. Expand
Ontogeny and symmetry of social partner choice among free-living yellow-bellied marmots
TLDR
Although reciprocity of affiliative exchanges within cohorts increased as individuals matured, competition among genetic relatives emerged early in ontogeny and persisted into adulthood, suggesting that close affiliates are each other's closest competitors. Expand
Temporal modification of social interactions in response to changing group demographics and offspring maturation in African lions (Panthera leo)
TLDR
It is suggested that social interactions between age classes may mediate recruitment and dispersal in lion prides and alter the strength of greeting networks among female lions. Expand
Ontogenetic change in determinants of social network position in the spotted hyena
TLDR
Social development is difficult to study, particularly in long-lived gregarious mammals, so little is known about the variables shaping the emergence during ontogeny of social roles played by adults. Expand
Kinship Shapes Affiliative Social Networks but Not Aggression in Ring-Tailed Coatis
TLDR
Kinship and age-sex class homophily in two groups of ring-tailed coatis (Nasua nasua) predicted the network structure of three different social behaviors: 1) association, 2) grooming, and 3) aggression. Expand
Male social relationships among wild Assamese macaques (Macaca assamensis)
General socioecological theories predict that in multi-male multi-female mammalian groups, males and females compete over resources of different nature. While females mainly compete over generallyExpand

Social and ecological determinants of fission–fusion dynamics in the spotted hyaena
TLDR
It is found that cooperative defence of shared resources during interclan competition and protection from lions were cohesive forces that promoted formation of large subgroups of various sizes inotted hyaenas. Expand
Evolutionary forces favoring intragroup coalitions among spotted hyenas and other animals
TLDR
Overall, hyenas made flexible decisions regarding whether or not to intervene in fights, modifying their tendency to cooperate based on multiple types of information about their immediate social and ecological environments. Expand

Rank-related partner choice in the fission–fusion society of the spotted hyena (Crocuta crocuta)
TLDR
It was found that subordinates who initiated group formation benefited by gaining social and feeding tolerance from dominants, and rates at which dominants provided coalitionary support to subordinates did not vary with AIs, which resemble patterns of association among cercopithecine primates.

Reconciliation in the Spotted Hyena (Crocuta crocuta)
Theory predicts that it should often be in the best interests of gregarious animals to repair social bonds damaged by within-group conflict. Indeed, reconciliation in many primates takes the form ofExpand

TLDR
The present paper focuses on the integration of cooperation and competition, and correlated behavioral mechanisms of aggression, dominance, and affiliation, within the social life of the spotted hyena. Expand

TLDR
It is proposed that on Agaltepec greetings are a conflict management mechanism used between males of similar ranks that allows males with conflicting interests to remain separated, and greetings may reduce tension during fusion events. Expand
