Exaggerated Sexual Swellings and the Probability of Conception in Wild Sanje Mangabeys (Cercocebus sanjei)
Females of several catarrhine primate species exhibit exaggerated sexual swellings that change in size and coloration during the menstrual cycle and, in some species, gestation. Although their function remains under debate, studies indicate that swellings may contain information males could use to discern ovulation and the probability that a cycle will be conceptive. Here we combine visual ratings of swellings with hormonal data for a group of Sa…
Ecology of reproduction in Sanje mangabeys ( Cercocebus sanjei ): Dietary strategies and energetic condition during a high fruit period
The ability to increase energy storage when food is abundant for later use during late gestation and early lactation is often considered the primary benefit of the capital breeding strategy (clustering conceptions during high food periods, HFP) that promotes reproductive success among females living in unpredictable environments. Capital breeding, however, may also enable preconceptive females to increase hormone production for ovulation, which h…

Affiliative behavior of adult female sooty mangabeys ( Cercocebus atys )
A 14‐month study of 30 adult female members of a captive group of sooty mangabeys investigated their affiliative interactions with group members of varying age and sex. The adult females preferentially affiliated with other adults and interacted less than expected with immature group members. Dyadic frequencies suggested especially frequent affiliation with the three resident adult males, although the pattern of interaction with each male was dis…
Absence of strongly kin‐preferential behavior by adult female sooty mangabeys ( Cercocebus atys )
The objective of this study was to test the hypothesis that kin‐preferential behavior would be present in sooty mangabeys ( Cercocebus atys ), a species taxonomically close to baboons and macaques. The affiliative behavior of the adult female members of a large captive group of these mangabeys was analyzed to test this prediction. These females groomed, were approached by, were in proximity to, and were in contact with their kin significantly mor…
Patterns of affiliation among immature rhesus monkeys ( Macaca mulatta )
The affiliative interaction patterns of the immature members of a group of rhesus monkeys at the Yerkes Regional Primate Research Center reflected a strong bias toward matrilineal kin, although this effect was modified by age and sex variables. Association with kin decreased with age, particularly for males. Juvenile males showed less of a kin bias in their behavior than did juvenile females, especially for grooming. Juvenile males also exhibited…
Birth-season interactions of adult female Japanese Macaques(Macaca fuscata) without newborn infants
Modification of aggression through socialization and the special case of adult and adolescent male rhesus monkeys ( Macaca mulatta )
Significant differences exist in the frequencies with which age‐sex classes of rhesus macaques engage in agonistic interactions with other age‐sex classes. In the study reported here, individuals engaged in significantly more agonistic interactions within their own age‐sex classes, but, adult females also showed significantly more aggression toward infants and young females whereas adult males directed significantly more aggression toward adolesc…
Matrilineal overthrows in rhesus monkey groups
Agonistic aiding: Kinship, rank, age, and sex influences
An analysis of 3,774 episodes of agonistic aiding collected during a two‐year study of a rhesus monkey group ( Macaca, mulatta ) indicated the differential influence of kinship and rank relationships on the participation of different age‐sex classes in both aid to victims and aid to aggressors. Most aiding favored victims rather than aggressors and was much more likely to occur when matrilineal kin were involved. Females were more likely to aid t…
