“…The combination of high male reproductive skew and long alpha tenures in capuchins creates a social system in which individuals have more co-resident close kin than is found in most other primate species. Previous studies have detected father-daughter inbreeding avoidance (Muniz et al, 2006(Muniz et al, , 2010, but females fail to favor paternal half siblings for affiliative interactions in the same way that they favor maternal siblings (Perry et al, 2008).…”

“…Such a case, however, did not arise (See Appendices, Table S5). In our previous genetic parentage analysis of infants that were conceived after habituation of their social groups, we have without exception been able to identify sires within the social group of the mother (Muniz et al 2006(Muniz et al , 2010, and the youngest age at which a male sired young was 7.72 years Perry, 2012). In one case in the Muniz dataset (2006Muniz dataset ( , 2010, two males were each genetically compatible as the father of a particular offspring, but one of these males was the full-sibling of the offspring and paternity was assigned to the older male.…”

“…This is because alpha males sire a disproportionately large number of offspring (Jack & Fedigan, 2006;Muniz et al, 2006Muniz et al, , 2010, generating a high frequency of paternal siblings within groups. For example, in the Lomas Barbudal population some 55% of capuchin dyads in the same cohort (less than two years apart in age) were paternal siblings (Perry et al, 2008) compared to 5% in Ngogo chimpanzees, 13% in Cayo rhesus monkeys, and 37% of Amboseli baboons (Langergraber et al, 2007).…”

If male dominance rank and group membership can remain relatively stable for longer than the typical gestation length for their species, then male dominance rank can serve as a cue to paternity for infants.…”

“…Thus, spatial proximity may also be a cue that infants use to detect which adult males are their fathers. Evidence for father-offspring kin recognition has been documented in savannah baboons (Buchan et al, 2003;Onyango et al, 2012), chacma baboons (Huchard et al, 2010(Huchard et al, , 2013, rhesus macaques (Langos et al, 2013), chimpanzees (Lehmann et al, 2006), and capuchin monkeys (Muniz et al, 2006(Muniz et al, , 2010. Additionally, paternal recognition and affiliative bias of fathers toward their own offspring may also lead paternal siblings to spend more time near each other because of mutual attraction to the same adult male.…”

The ability to recognize kin has important impacts on fitness because it can allow for kinbiased affiliative behaviors and for avoidance of mating with close kin. While the presence and effects of kin biases have been widely studied, less is known about the process by which animals recognize close kin. Here we investigate potential cues that white-faced capuchin monkeys (Cebus capucinus) may use to detect half-siblings and closer kin. We focus on the first year of life in a sample of 130 infant (n=65 infant females) wild capuchins from the Lomas Barbudal population in Costa Rica. We show that (1) infant relatedness to juvenile and adult males at the level of half-sibling and higher can be predicted by male alpha status, spatial proximity, and age proximity, and that (2) infant relatedness to juvenile and adult females at the level of half-sibling or higher can be predicted by spatial proximity (but not age proximity). Furthermore, (1) the identities of infants' fathers can also be predicted by male alpha status and the spatial proximity between infants and adult males, and (2) age proximity (but not spatial proximity) is predictive of paternal sibship. These results suggest that infant capuchins have access to multiple cues to close relatedness and paternal kinship, though whether infants use these cues later in life remains to be explored in future research.Keywords: kin recognition, age proximity, early social familiarity, male dominance, The ability to recognize kin has many adaptive benefits. It can help organisms increase their inclusive fitness by allowing them to allot a disproportionate amount of affiliative behaviors and coalitionary support toward individuals with which they share a larger proportion of their genes (Hamilton, 1964). Furthermore, by allowing individuals to recognize kin and discriminate against them in a mating context, kin recognition mechanisms can facilitate avoidance of the deleterious effects of close inbreeding (Charlesworth & Charlesworth, 1987).We define kin recognition as the ability to identify and distinguish kin from non-kin, or more closely related kin from more distant kin, regardless of the mechanism or mechanisms through which it is accomplished, and regardless of whether it actually leads to differential treatment of individuals (i.e. kin discrimination). In this sense, we take on a broad as opposed to narrow definition of kin recognition (see Penn & Frommen, 2010). We consider the related term kin bias to be the differential treatment of kin versus non-kin (or close kin from distant kin), though not exclusively as the result of kin recognition.Kin recognition has been documented in a wide array of animal taxa, including, to name only a few: Artic charr (Salvelinus alpinus) (Winberg & Olsén, 1992;Olsén & Winberg, 1996), spadefoot toads (Scaphiopus bombifrons) (Pfennig et al., 1993), Golden hamsters (Mesocricetus auratus) (Mateo & Johnston, 2000), and Belding's ground squirrels (Spermophilus beldingi) and Arctic ground squirrels (Spermophilus parryii) (Holmes & S...

White-faced capuchin males disperse from their natal group at around 4.5 years of age, but there is much variation in dispersal timing: our youngest confirmed disperser was 19 months and the oldest 11 years old. In this study, we investigate possible factors influencing dispersal decisions in this species. Between 1983 and 2010, 64 males were born into three study groups in Santa Rosa National Park, Area de Conservación Guanacaste, and Costa Rica. As of August 2010, 21 died or were presumed dead (<14 months), 13 remained natal residents, and 30 were presumed dispersers. We used backward logistic regression to identify proximate factors that predict the occurrence of male natal dispersal. The occurrence of a takeover (significant positive association) and group size (nonsignificant negative association) were included in the model. Male age, number of maternal brothers, and number of adult males were not significant predictors of natal dispersal. The resultant model correctly classified 97% of dispersed and 89% of resident natal males, for an overall success rate of 95%. The occurrence of a group takeover was the strongest predictor of male dispersal, with natal males being 18.7 times more likely to disperse in the context of a group takeover than during peaceful times. A linear regression model showed that the tenure length of a male's probable father influences the age of natal dispersal, explaining 15% of the observed variation in age. However, when our oldest disperser was removed (an outlier) this effect disappeared. Collectively, these results indicate that group instability, as evidenced by the occurrence of a takeover, shorter tenure length of a natal male's father, and smaller group size, triggers natal dispersal in this species while the converse leads to a delay. These data add to our growing evidence of the enormous impact that takeovers have on the behavioral ecology of this species.
