| Abstract: | Estimates of alloparental behavior on the basis of kinship and maternal qualities of permissiveness/restrictiveness were examined in vervet mother-infant pairs. Amounts of alloparenting were examined for the subgroup categories female siblings, juvenile females, subadult nulliparous females, adult females, males, and yearlings. Analysis of the six subgroups for months 1 through 6 revealed that the most alloparenting occurred in month 1 with siblings caretaking more than any other subgroup. By month 2 subadult nulliparous females were the most frequent caretakers. Correlations between kin alloparenting and maternal permissiveness/restrictiveness indicated that kinship was a better predictor of alloparenting than maternal qualities of permissiveness. Additionally, examination of the data on maternal behaviors towards related and unrelated individuals revealed significant differences by months. |
