Kin-biased social behaviour in wild adult female white-faced capuchins, Cebus capucinus
Section snippets
Study Species and Site
Here we report results from a group (Abby's group; Perry 1996) of habituated white-faced capuchins residing in Lomas Barbudal Biological Reserve, Costa Rica, and on nearby public and privately owned land (10°29–32′N, 85°21–24′W). The area consists largely of highly seasonal tropical dry deciduous forest traversed by several permanent streams (Frankie et al. 1988). We habituated the group in 1990. Observations were conducted during three months in 1990, 22 months during 1991–1993, 6 months in
Matrilineal Relatedness and Dominance Rank
In Abby's group, as female group size increased over the 10 years of the study, mean matrilineal relatedness declined (Fig. 2, Table 5). Table 2 shows (a) each female's observed dominance rank in 1991–1993, 1997 and 2001 and (b) the rank she would be expected to hold if our subjects followed the ‘youngest ascendancy’ rule by which each female occupies a rank below her mother and above her next oldest sister. Using the genealogical structure we consider most likely (see above and Fig. 1), the
Discussion
Our results reveal that the white-faced capuchins at Lomas Barbudal are more closely related to more of their fellow groupmates than what has been reported in group-living wild primates. Of our 12 female subjects, 10 were always co-resident with their mother and/or at least one adult daughter or maternal sister (primary kin) and only one was never co-resident with adult female primary kin; the subjects had an average of 2.7 such kin (range 0–5). Seven subjects always resided with at least four

Affiliative behaviors directed towards kin have been reported across several mammalian taxa (e.g. wedge-capped capuchin, Cebus olivaceus: O’Brien and Robinson, 1991; yellow baboons, Papio cynocephalus: Silk et al., 2006; sperm whales, Physeter microcephalus: Gero et al., 2008; white-faced capuchins, Cebus capucinus: Perry et al., 2008; captive degus, Octodon degus: Jesseau et al., 2009; spotted hyenas: Crocuta crocuta: Smith et al., 2010; bottle nose dolphins, Tursiops truncates: Diaz-Aguirre et al., 2020) and benefits may be provided to kin who affiliate in primate species (Silk et al., 2003; Charpentier et al., 2007). Conversely, in feral horses, affiliation between unrelated females appears to provide positive direct fitness consequences, as it increases foal birth rates and foal survival (Cameron et al., 2009).
