Sexual behavior by infecundable females, and by same-sex and adult-immature dyads, occurs in wild and captive bonobos (Pan paniscus). Proposed functions of these behaviors, in social primates generally, include practice, paternity confusion, exchange, and communication as well as appeasement. We used this framework to interpret and to compare observations of sexual behavior in a captive bonobo group and a wild white-faced capuchin (Cebus capucinus) group. In both species, (a) sexual behavior… 
Analysis of tufted capuchin (Cebus apella) courtship and sexual behavior repertoire: changes throughout the female cycle and female interindividual differences.
Sexual solicitations and initiative (proceptivity, sensu Beach [1976] Horm Behav 7:105-138) are important components of the sexuality of females of many primate species. In the tufted capuchin (Cebus
Anecdotic observations of homosexual behaviour among male capuchin monkeys (Sapajus sp.)
Four events of male-male mounts were observed, involving six individuals — two juveniles and four adults, which do not seem related to hierarchical or age group factors, but could be related to getting access to the experimental apparatus.
Sexual Behavior of Immature Tibetan Macaques (Macaca thibetana)
This study compared rates of sexual behavior among four age and sex classes of 26 immature 12 Tibetan macaques at Mt. Huangshan, China and found that older females and older males exhibited rates that were variably both higher and lower than other age classes across the five aspects.
Sex and strife: post-conflict sexual contacts in bonobos
Sexual contacts are thought to play an important role in regulating social tension in bonobos (Pan paniscus), and are especially common following aggressive conflicts, either between former opponents
Behavioral indicators of ovarian phase in white‐faced capuchins (Cebus capucinus)
The finding that females exhibit little proceptive behavior, but that copulations and male courtship are nonetheless concentrated in periovulatory phases suggests that even though females do not provide behavioral and morphological cues to ovulation, males are still able to detect it.
Integration of New Males into Four Social Groups of Tufted Capuchins (Cebus apella)
Affiliative relationships between the males and nonproceptive females developed slowly, and while male-female aggression was mild, aggression among adult males (familiar and unfamiliar) had the potential to be severe.
Social–sexual behavior seasonality in captive beluga whales (Delphinapterus leucas)
Observation of wild beluga whales (Delphinapterus leucas) indicates that this species breeds seasonally, and hormonal assays of captive animals show corresponding fluctuations in reproductive


Sociosexual Behavior Used for Tension Regulation in All Age and Sex Combinations Among Bonobos
This author encountered such a situation during his studies of bonobos, and it is of particular interest because this little-known ape species, together with the chimpanzee, is the closest relative of humans.
Female relationships in bonobos(Pan paniscus)
Analysis of this bonding phenomenon sheds light on when, where, and how the authors should expect unrelated human females to bond with one another by demonstrating that bonding is not dependent on access to one’s relatives but rather on an environmental situation in which female aggregation is possible, coupled with an incentive for cooperation.

It is concluded that phylogenetic affinity is a good predictor in that C. capucinus are similar to other species of Cebus in many patterns of sex-differentiated behavior and the general model of sex differences in female philopatric, male-dispersal societies, which was originally developed for Old World species, also accurately predicts several aspects of social behavior in C. Capucinus.
Sexual swelling, receptivity, and grouping of wild pygmy chimpanzee females at Wamba, Zaïre
Although pregnant females and those with newborn infants were sexually inactive, females with infants older than 3 years copulated as frequently as those without dependent infants and copulation was mostly restricted to the maximum swelling phase.
The evolution of sexuality in chimpanzees and bonobos
The evolution of nonconceptive sexuality in bonobos and chimpanzees is discussed from a functional perspective. Bonobos and chimpanzees have three functions of sexual activity in common (paternity
Sexual Behavior of Pan paniscus under Natural Conditions in the Lomako Forest, Equateur, Zaire
Allusions to the flexible sociosexual behavior of the pygmy chimpanzee (Pan paniscus) have been incorporated into the “bonobo model” of human evolution (Zihlman, 1979; Zihlman and Cramer, 1978;
Female Choice and Mating System of the Brown Capuchin Monkey Cebus apella (Primates: Cebidae)
Abstract and Summary The mating system of wild brown capuchin monkeys, Cebus apella, was studied during four years in Peruvian rainforest. The most striking feature of estrus is active continuous
A comparison of the mating behavior of adolescent and adult female rhesus macaques (Macaca mulatta)
Compared to adult females, adolescents presented sexually to males at higher rates; copulated more frequently with rankless young male, and extra-group males; and, in one of two mating seasons, were ignored more frequently by males to whom they presented sexually.
Social Relationships of Male Bonnet Macaques: Male Bonding in a Matrilineal Society
Bonnet macaques (Macaca radiata) represent one of several exceptions to this general pattern as adult males in this species frequently sit together, groom, huddle, greet, and support one another.
Social relationships and ritualized greetings in adult male baboons (Papio cynocephalus anubis)
Greetings involving exchanges of ritualized sexual gestures are a common form of interaction among adult male baboons, although relatively little attention has been paid to them. In this study, we
