Two approaches were taken to investigating constraints on kinship in predicting social behaviour in the vervet monkey Cercopithecus aethiops sabaeus in Barbados. in Chapter 1, behavioural interactions between an adult female and an unrelated adopted infant were compared with those between mothers and their natural offspring. The adoptive mother consistently scored higher than mothers with their own offspring in pre-weaning contact-maintaining behaviours, but the difference was not statistically significant. Post-weaning aggression and support interactions between mothers and infants also suggest no difference in parental behaviour and parental costs between adoptive and natural mothers. During post-weaning, the adopted infant was more aggressive to other troop members, and provided more maternal support in aggressive disputes, than another high ranking infant of the same year. / In Chapter 2, effects of kinship on the distribution of aggression and support in feral vervet monkeys were investigated by comparing aggression and support between full sibs and maternal half sibs (within matrilines), and between paternal-half sibs and unrelated juveniles (between matrilines). The strong tendency to behave affiliatively to matrilineal members in Old World monkeys, and maternal control of offspring rank within matrilines, may constrain the ability of offspring to enhance inclusive fitness by behaving differentially to either paternal or maternal sibs based on their degree of relatedness.
