Kinship, association, and social relationships in rhesus monkeys ( Macaca mulatta )
Data on social interactions with matrilineal kin were collected from two groups of rhesus monkeys for 6 years. All behavioral states, including time within one meter of another, involved kin more often than would be expected by chance. Significant associations were also found between kinship and the frequencies of various forms of agonistic as well as affiliative acts. Frequency of social interaction, however, was not a simple function of time in…
Sex differences in adolescent rhesus monkey ( Macaca mulatta ) Behavior
Sex differences in the behavior of 2.5‐ to 4.5‐year‐old rhesus monkeys, living in two social groups approximating natural compositions, were studied over a period of 3 years. Both sexes interacted significantly more often with members of their own sex in agonistic and affiliative interactions even when total rates and durations for male and female subjects did not differ. Strong sexual segregation was also seen in proximity, nonspecific contact, …
Testosterone changes during the period of adolescence in male rhesus monkeys ( Macaca mulatta )
Testosterone levels of 59 male rhesus monkeys were monitored over a period of 5 years. Longitudinal comparisons revealed consistent rises in mid‐morning levels of circulating hormone in successive years from age 2.5 to 6.5 years of age, whereas cross‐sectional comparisons failed to detect significant differences among the older subjects. The first mid‐morning hormonal elevation could be detected in some males as young as 2.5 years of age, whereas…
Seasonal weight changes in male rhesus monkeys ( Macaca mulatta )
Adult male rhesus monkeys lose weight during the breeding season and regain it during the nonbreeding season. The annual pattern of maximum weight gain just prior to the onset of breeding resembles the seasonal “fattening” seen in squirrel monkeys, but the period of weight gain is less discrete. The magnitude of weight change is less in younger males, in that sexually immature males gain weight in both seasons, but significantly less during the b…
Wounding patterns in three species of captive macaques
The incidence of wounding in captive groups of rhesus ( Macaca mulatta ), pigtail ( M. nemestrina ), and stumptail ( M. arctoides ) macaques was studied for 21 months. Groups were monitored daily for evidence of wounding. Wounded animals were captured, treated by veterinary staff, and returned following recovery. Records were kept on the age, sex, and species of the recipient, along with the type and location of wound. In each species of macaque,…
