“…In the context of collective movements, cohesion could be interpreted as cooperation between group members and therefore reflecting their social style (Aviles, 1999). Such anonymous mimetism was also found in the relatively tolerant white-faced capuchin monkeys (Cebus capucinus) (Leca et al, 2007;de Marco et al, 2008) during induced collective movements showing high group cohesion (Meunier et al, 2006). Moreover, joining the sub-group with the higher number of individuals is a way of maintaining group cohesiveness or advantages in terms of protection or knowledge about resource location (Kerth et al, 2006;Lehmann and Boesch, 2004;Wittemyer et al, 2005).…”

SUMMARYLiving in groups necessarily involves a certain amount of within-group competition for food. Group members may have different motivations, implying the reaching of a consensus to stay cohesive. In some cases individuals fail to reach a common decision and the group splits; this can be temporary, as seen in fission-fusion dynamics, or even irreversible. Most studies on fission-fusion dynamics published to date have focused on the influence of environmental constraints on sub-grouping patterns, but little is known about how social relationships affect individual choices for sub-groups. In this study, we used an agent-based model to understand the mechanisms underlying group fission in two semi-free-ranging groups of macaques: one group of Tonkean macaques (Macaca tonkeana) and one of rhesus macaques (M. mulatta). The results showed that sub-grouping patterns were mainly influenced by affiliative relationships. Moreover, the species-specific social style appeared to affect the probability of choosing a particular sub-group. In the tolerant Tonkean macaques, mechanisms underlying sub-grouping patterns resembled anonymous mimetism, while in the nepotistic rhesus macaques, kinship influenced the mechanisms underlying group fissions. As previous studies have shown, fission-fusion society may be a way to avoid social conflicts induced either by food or by social competition. Supplementary material available online at

“…This suggests that as diurnal species evolve to live in larger groups, thereby reducing the risks of predation (van Schaik, 1983), natural selection favors increased facial mobility for more effective facial expression. Given the importance of facial displays in conflict management and social bonding (e.g., Waller and Dunbar, 2005;Flack and de Waal, 2007;De Marco et al, 2008), the correlation between facial mobility and social group size implies that the ultimate function of facial expression is group cohesion (Maestripieri, 1999).…”

“…This can be followed by reconciliation and affiliation in some species (Preuschoft, 1992). In contrast, other species use the SBT only in affinitive interactions (Preuschoft and van Hooff, 1997), and never in response to aggression (Visalberghi et al, 2006;De Marco et al, 2008). For example, the use of the SBT among Tonkean macaques (M. tonkeana) does not correlate with measures of dominance or subordination, but facilitates social play in this species (Thierry et al, 1989).…”

Facial mobility, or the variety of facial movements a species can produce, is likely influenced by selection for facial expression in diurnal anthropoids. The purpose of this study is to examine socioecological correlates of facial mobility independent of body size, focusing on social group size and arboreality as possible evolutionary agents. Group size was chosen because facial expressions are important for group cohesion, while arboreality may limit the utility of facial expressions. Data for 12 nonhuman anthropoid species were taken from previous studies and analyzed using a phylogenetic generalized least-squares approach. Regression results indicate that group size is a good predictor of facial mobility independent of body size. No statistical support was found for the hypothesis that arboreality constrains the evolution of facial mobility. The correlation between facial mobility and group size may be a consequence of selection for more effective facial expression to help manage conflicts and facilitate bonding in larger groups. These findings support the hypothesis that the ultimate function of facial expression is related to group cohesion.

“…In contrast to FACS, facial expressions used in social communication research are categorized according to multiple simultaneous muscle movements that have commonly accepted configurations such as "fear grimace" and "relaxed open mouth display" (Parr et al, 2005;Waller and Dunbar, 2005;Parr and Waller, 2006;De Marco et al, 2008). This is a "top-down" system of coding, with expressions then counted or timed for analysis.…”
