TL;DR

The behavior and organization of a group of 33 juvenile rhesus monkeys removed from a single free-ranging group were found to parallel closely intact rhesu social groups, with the basis of much of the behavior shown by the juveniles found to be the matrilineal kin bonds brought from their natal group.

Abstract

Abstract The behavior and organization of a group of 33 juvenile rhesus monkeys removed from a single free‐ranging group were found to parallel closely intact rhesus social groups. Dominance ranking among the juveniles was 95% predictable from prior knowledge of mothers' ranks. Grooming, sitting close together, sitting touching, and play were found to occur much more frequently between matrilineal kin than expected from random selection of partner. Some estrous behavior was observed, including two instances of peri‐menstrual estrus. One lengthy homosexual interaction between two two‐year‐old females was observed. The basis of much of the behavior and organization shown by the juveniles was found to be the matrilineal kin bonds brought from their natal group.

Interest in the evolution of behavior leads one naturally to the study of nonhuman primates, and surprisingly, little systematic information had been gathered with regard to man's close phylogenetic neighbors.

It is shown that a rhesus female and her offspring can continue to maintain a distinct relation into the offspring's physical maturity, and that the offspring often develops its strongest relations with monkeys of its own genealogy.

A few females who failed to conceive during the fall breeding season showed cyclic estrous behavior throughout the entire annual cycle, producing a shorter mean estrous cycle length than reported by other workers.

With few exceptions, the pattern of genealogical, cross-genealogICAL, and adult male dominance relations in the group under study was consistent with data reported for a small social group on Cayo Santiago and for Japanese macaques.

It is suggested that the bond between the adult males is per se an adequate foundation for the sociability of these monkeys enabling the breeding pairs to remain together when sexual conflict is aroused by the simultaneous presence of more than one oestrus female.

Four changes in the adult female dominance hierarchy were studied in a small, enclosed social group of rhesus monkeys and one 2 1 2 -year-old female acted independently of the mother and consistently achieved a social rank higher than that of theMother when the mothers rank fell.

During a behavioral study of free-ranging rhesus monkeys, non-pregnant females were observed to show sexual behavior both at mid-menstrual cycle and peri- menstrually, and the basis of the dual estrous cycle is explained.
