AbstractWe investigated dyadic grooming relationships in a captive group of bonobos (Pan paniscus) and questioned what social function grooming fulfils in the 'market of services and favors'. Hereto we examined which of two theoretical models - grooming for support (Seyfarth, 1977, 1980) or grooming according to the similarity principle (de Waal & Luttrell, 1986) - best accounted for the observed grooming distribution. Similarity in traits did not correlate with increased grooming or close proximity among the individuals. Therefore, the similarity hypothesis was rejected. Seyfarth's model of rank-related grooming was largely confirmed. The animals distributed their grooming according to the rank of the receivers. We found an exchange between grooming and receipt of support. There was more grooming up than down the hierarchy. However, not all predictions about rank-related competition over grooming were confirmed. We found that dyadic grooming reciprocity indeed increased with decreasing rank distance. Yet, there was no increase of grooming within the dyad with decreasing rank distance and high ranking individuals were not competed over at the highest rates. The observed correlation between grooming and support received represents an important fit with Seyfarth's prediction, but does not allow for conclusions about underlying causal processes. Other causal explanations, besides the 'groom to receive support' hypothesis, that could explain a similar correlation are discussed.

AbstractHere we examine the effects of maternal kinship, reciprocity, and dominance rank on the social relationships of female baboons (Papio cynocephalus ursinus) in a well-habituated, free-ranging group in the Okavango Delta of Botswana. These data are useful for testing comparative hypotheses about the ecological and demographic factors that shape the evolution of social organization in primates and other animals. In this group, adult females had well-differentiated grooming relationships with one another, and limited their grooming to a relatively small subset of available partners. Although there were 19 adult females in the group, the average female groomed only 8 other females, and devoted at least 5% of her grooming to only four other females. Females groomed maternal kin at significantly higher rates and for significantly longer periods than they groomed other females. The bias in favor of maternal kin was not an artifact of a general attraction toward females of adjacent rank. However, members of high-ranking lineages did devote a relatively greater fraction of grooming to maternal kin than members of low-ranking lineages did. Females most often groomed the females from whom they received the most grooming and grooming was very evenly balanced within the majority of dyads. Female rank had little impact upon grooming patterns and there was no evidence that females competed overtly over access to high-ranking partners.

The replacement of a sexually mature, but sexually inactive, male by a novel mature male in a small colony of Macaca fascicularis brought about changes in social behaviour and structure. Particularly striking were the heightened levels of all sexual activity, especially in the females' invitation to the male to copulate. Cohesiveness around the male increased. Increased levels of agonism were noted and changes in the agonistic female hierarchy resulted. The grooming relationships in the colony were also significantly altered.
