“…Judge concluded that the findings supported the VRH under the assumption that the extent of shared interests, hence relationship value, varies inversely with rank distance. However, rather than test the assumption, he merely cited Seyfarth's (1977) statement that closely ranked baboons tend to have strong social bonds. Castles and Whiten conceded that rank distance was an indirect measure of relationship quality and refrained from making strong statements about the VRH.…”

“…Most of studies on the link between social structure, grooming and group size (Kudo and Dunbar, 2001, Lehman et al, 2009) followed standard practices in social network analyses and used a criterion for distinguishing casual from meaningful relation ships. Modeling permits, without using this arbitrary criterion for preferred relationships, the simulation of interactions between group members (Seyfarth, 1977;Bryson et al, 2007;Meunier et al, 2006;Sellers et al, 2007;Puga Gonzalez et al, 2009) and also resulting sub grouping patterns (i.e. how individuals are sub grouped; Ramos Fernandez et al, 2006).…”

a b s t r a c tIn social animals, fission is a common mode of group proliferation and dispersion and may be affected by genetic or other social factors. Sociality implies preserving relationships between group members. An increase in group size and/or in competition for food within the group can result in decrease certain social interactions between members, and the group may split irreversibly as a consequence. One individual may try to maintain bonds with a maximum of group members in order to keep group cohesion, i.e. proximity and stable relationships. However, this strategy needs time and time is often limited. In addition, previous studies have shown that whatever the group size, an individual interacts only with certain grooming partners. There, we develop a computational model to assess how dynamics of group cohesion are related to group size and to the structure of grooming relationships. Groups' sizes after simulated fission are compared to observed sizes of 40 groups of primates. Results showed that the relationship between grooming time and group size is dependent on how each individual attributes grooming time to its social partners, i.e. grooming a few number of preferred partners or grooming equally or not all partners. The number of partners seemed to be more important for the group cohesion than the grooming time itself. This structural constraint has important consequences on group sociality, as it gives the possibility of competition for grooming partners, attraction for high ranking individuals as found in primates' groups. It could, however, also have implications when considering the cognitive capacities of primates.

“…Food is the limiting resource in nature that would lead to the establishment of a dominance hierarchy. However, in an established hierarchical system, access to dominant females to solicit agonistic support itself becomes a limiting resource, and the subordinate females try to achieve this by grooming dominants (Seyfarth 1977). In macaques, grooming therefore is upward in the hierarchy.…”

Dominance hierarchy and social grooming in female lion- tailed macaques (Macaca silenus) in the Western Ghats, India

This article reports the structure of dominance and its relationship with social grooming in wild lion-tailed macaque females. The strength of dominance hierarchy was 0.79 on a scale of 0 to 1 indicating a moderate linearity in the ranking system. Dominance scores were converted into an ordinal as well as an interval scale. Grooming scores were also converted into interval scales using standard scores. Grooming received and grooming given correlated positively and negatively respectively with dominance ranks indicating that high ranking females received more and gave less grooming. Grooming was also positively related to encounter rates for dyads of females. More grooming among adjacent ranks, and grooming being more reciprocal, occurred only in the case of dominant females. The grooming patterns, therefore, appeared to be more of despotic than egalitarian nature. While ranking macaques into different Grades of social systems ranging from despotic to egalitarian, Thierry (2004) has placed lion-tailed macaques in Grade 3 corresponding to the 'relaxed' social system. Our results indicate that the grooming and dominance relationships in this species are more despotic, and hence, the Grade for this species requires to be shifted toward 2 or 1.[Singh M, Krishna B A and Singh M 2006 Dominance hierarchy and social grooming in female lion-tailed macaques (Macaca silenus) in the Western Ghats, India; J.
