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

Kinship, association, and social relationships in rhesus monkeys (Macaca mulatta)

Although animals spent more time with kin than nonkin they had more aggressive interactions with Kin, and aggression was biased toward the more serious forms of expression in interactions with kin.

Modification of aggression through socialization and the special case of adult and adolescent male rhesus monkeys (Macaca mulatta)

As a consequence of adult response to the agonistic behavior of adolescent males, maturing males selectively target other older males, avoid aggression against females and immatures; (2) form alliances with other males; and (3) become progressively isolated from their matrilines.

Sex Differences in the Development of Aggressive Behavior in Rhesus Macaques (Macaca mulatta)

This work analyzed aggressive interactions in rhesus macaques from birth to sexual maturation (before male dispersal), including male and female focal subjects, and used powerful multivariate statistical analysis.


The asymmetry in affiliation and aggression between maternal and paternal half siblings, and the effect of age proximity on partitioning social interactions suggests that context-dependent kin discrimination characterises rhesus macaques.

Paternal kin bias in the agonistic interventions of adult female rhesus macaques (Macaca mulatta)

Molecular genetic kinship testing was used to assess whether adult female rhesus macaques from the free-ranging colony of Cayo Santiago bias their interventions in ongoing dyadic aggressive interactions towards maternal and paternal half-sisters compared with unrelated females, and confirmed the general view that coalition formation in female mammals is a function of both the level of maternal relatedness and of the costs of intervention.

Growing into adulthood—a review on sex differences in the development of sociality across macaques

The emergence of sex differences in mother–offspring bonds is highlighted, as macaque mothers form stronger bonds with daughters, while being more aggressive towards sons, possibly contributing to maintain female philopatry and/or male dispersal.

Models of Affiliative Relationships Among Free-Ranging Rhesus Monkeys (Macaca Mulatta)

Suggestions that adult female relationships are organized around several levels of kinship through maternal lines, and not simply by crude distinctions of kin vs non-kin, are supported.



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

Patterns of fight interference in free-ranging rhesus monkeys

The findings reinforce the notion that females are the stable and central part of a rhesus monkey social group and suggest that interference plays a role in the maintenance of group stability and cohesion.

Age-sex differences in the expression of agonistic behavior in rhesus monkey (Macaca mulatta) groups.

Adolescent males received high frequencies of aggressive responses, and this is hypothesized to account for the marked shift in adult male patterns of participation in intragroup agonistic interactions, as relative to females whose basic pattern of agonistic expression does not change with age.

Social rank, observability, and sexual behaviour of rhesus monkeys (Macaca mulatta).

The frequency of mating activity in freeranging social bands of rhesus monkeys in the La Parguera, Puerto Rico colony, when corrected for the observability of males, revealed no significant differences in the performance of sexual behaviour by males of differing social ranks.

Reconciliation and Redirected Affection in Rhesus Monkeys

The question whether rhesus monkeys reconcile was empirically translated as: Do they seek non-agonistic contact with former adversaries? The study concerned a captive group of forty-one monkeys,

Rank Relations in Vervet Sisters: A Critique of the Role of Reproductive Value

It is suggested that observations of reversal occurring prior to the age of peak reproductive value may be explained by the relative vulnerability ofoffspring, i.e., the greater vulnerability ofyounger offspring may have to be balanced by more maternal support, and dependent rank reversal may be occurring from birth.

Intragroup agonistic behavior in rhesus monkeys (Macaca mulatta)

L'agressivite au sein d'un groupe de M.m. se limite a des manifestations sans contact corporel ; il y a tres rarement des blessures; plus de la moitie des comportements agressifs se traduisent par la
