Paternal kin recognition and infant care in white-faced capuchins (Cebus capucinus).

چکیده
Evidence for paternal kin recognition and paternally biased behaviors is mixed among primates. We investigate whether infant handling behaviors exhibit paternal kin biases in wild white-faced capuchins monkeys (Cebus capucinus) by comparing interactions between infants and genetic sires, potential sires, siblings (full sibling, maternal, and paternal half-siblings) and unrelated handlers. We used a linear mixed model approach to analyze data collected on 21 focal infants from six groups in Sector Santa Rosa, Costa Rica. Our analyses suggest that the best predictor of adult and subadult male interactions with an infant is the male's dominance status, not his paternity status. We found that maternal siblings but not paternal siblings handled infants more than did unrelated individuals. We conclude that maternal but not paternal kinship influence patterns of infant handling in white-faced capuchins, regardless of whether or not they can recognize paternal kin. Am. J.

Predictors of reproductive success in female white-faced capuchins (Cebus capucinus).
Early investigations into variable reproductive success in nonhuman primates tended to focus on the benefits conferred by high dominance rank. However, the effect of high rank on individual reproductive success has been found to vary both intra- and interspecifically, requiring researchers to expand their investigations to include additional factors. Here we examine the age and rank of the moth...

Evaluating social influences on food-processing behavior in white-faced capuchins (Cebus capucinus).
Interpopulation variability in patterns of food processing, similar to what is described as "traditional" or "cultural" variation in chimpanzees (Pan troglodytes) and orangutans (Pongo pygmaeus), was identified in white-faced capuchins (Cebus capucinus). However, recent comparisons of food processing in capuchins were conducted only at the population level, with relatively little attention give...
متن کاملDominance style of female white-faced capuchins.
Dominance style, the level of tolerance displayed by dominant individuals toward subordinate ones, is exhibited along a continuum from despotic to relaxed. It is a useful concept to describe the nature of dominance relationships in macaque species and it bridges among multiple features of dominance hierarchies, aggression, kinship and conflict resolution. Capuchins share many behavioral similar...
متن کاملA coprological survey of parasites in white-faced capuchins (Cebus capucinus) from Sector Santa Rosa, ACG, Costa Rica.
Neotropical primate parasitology has been dominated by studies of howler monkeys (Alouatta spp.), whereas the literature on the parasites of other platyrrhines is relatively sparse. We analysed the faeces of white-faced capuchins (Cebus capucinus) in a Costa Rican tropical dry forest and recovered 8 parasite taxa (Filariopsis barretoi,Giardia duodenalis, Strongyloides sp., Prosthenorchis sp., a...
