“…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).…”

“…These migrant males, however, were assumed to be unrelated to monkeys in our study group unless they were later determined to be the fathers of infants. Since males of Cebus capucinus often emigrate with natal kin (Perry, 2012, Perry et al, 2008Wikberg et al, 2014), it is likely some non-natal males that were assigned as nonkin of infants are actually the paternal uncles (or more distant kin) of infants. Of the 39 males known to have sired infants at Lomas Barbudal, 56.4% (n=22) had unknown parents.…”

“…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). In addition, the Lomas Barbudal population is characterized by long male tenures, as several alpha males have been documented to hold their rank for more than six years and the longest alpha tenure has been estimated (through genetic paternity data) to be 17 years.…”

Cues to kinship and close relatedness during infancy in white-faced capuchin monkeys, Cebus capucinus

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...

“…37 Recent observations indeed show a stronger kin-bias in behavior in capuchin groups with higher variance in relatedness. 54 How to incorporate these findings into the model is an open question at the moment. One solution might be to add one or more factors, such as variability in relatedness, in addition to WGC to explain the occurrence of matrilineal hierarchies (for discussion see Archie and coworkers.…”

“…Although behavioural bias towards paternal kin has indeed been described in some primates with stable and cohesive group membership Perry et al 2008;, the extent to which animals favour their paternal kin (over unrelated individuals) is not well described in species within higher-fission fusion dynamics. Rates of some social interactions, but not others, differed between paternal half-sibling pairs and unrelated pairs of spotted hyenas (Wahaj et al 2004), but chimpanzee paternal half-brothers did not show preferences for affiliating or cooperating (Langergraber et al 2007).…”

Personalities, social patterns, and reproductive success in female eastern grey kangaroos (Macropus giganteus)

Sociality evolves when the benefits of grouping outweigh the costs. Living with relatives can sometimes help to offset some of these costs, and fission-fusion dynamics can help to maximize benefits. Individual differences in sociability can exist and such differences have been linked to fitness consequences in several species. Differences in other personality traits, those that show within-individual consistency and significant differences among individuals, can also influence fitness. However, more research is needed on the relationships among personality traits, and their fitness correlates, in natural populations to better understand the adaptive nature of individual differences in personality traits.The overall objective of my PhD was to understand some of the constraints, correlates, and fitness consequences of individual differences in sociability in an herbivorous marsupial, the eastern grey kangaroo (Macropus giganteus). Eastern grey kangaroos forage in open-membership groups that frequently change in size and composition. Females show natal philopatry but not complex cooperative interactions. I conducted field observations of a wild population of eastern grey kangaroos in Sundown National Park in south-east Queensland, Australia, over more than two years. I documented life-history traits, grouping patterns, and behavioural responses of over 240 identified females, and analysed these data in addition to two previous years' worth of data collected by other researchers.My first aim (Chapter 2) was to determine the extent to which females' boldness and sociability measures were consistent over multiple years, and how stable correlations among these traits were across time. I also determined whether females' association patterns could be explained to some degree by similarity in boldness, as measured by flight initiation distance. Individual differences in boldness and two measures of sociability (foraging group size and number of preferred associates) were significantly consistent across four years, and correlations between these traits tended to show consistency over time. Some social assortment between females of similar personalities was observed, but this was not consistent over time, and boldness was not related to preferential associations, suggesting that females were not actively choosing to associate with others based on their similarity in personality.In Chapter 3, I explored the relationships between kinship and association strengths among female kangaroos over four years. I used both biparental genetic relatedness estimates and mother-daughter relationships as measures of kinship, and conducted one set of analyses that considered both adults iii and sub-adults, and one restricted to adult females. Both analyses showed weak, yet significant, positive correlations between association strengths and biparental relatedness for all four years.Mother-daughter status of adult females explained almost twice the variation in pairs' association strengths as did biparental relatedness. Although spac...
