An Unexpected Audience Effect and No Indirect Reciprocity of Grooming in Wild Geoffroy's Spider Monkeys ( Ateles geoffroyi )
Indirect reciprocity consists of performing an act that benefits a recipient while increasing the chances of receiving cooperation from a bystander. While widespread in humans, evidence of indirect reciprocity in nonhuman animals is scarce. Indirect reciprocity may involve an audience effect if cooperation increases in the presence of an audience. We investigated indirect reciprocity and audience effects in wild Geoffroy's spider monkeys ( Ateles…
Does Knowledge of the Partner's Need Affect Food Sharing in Tufted Capuchin Monkeys
The ability to understand the internal (psychological or physiological) states of others can be adaptive in both cooperative and competitive settings. In this study, we tested whether tufted capuchin monkeys ( Sapajus spp.) altered their willingness to share part of their food with a partner in relation to having recently seen it eating. We first gave partners food (banana, carrot, or nothing) that could not be shared with the subjects, and then …
Social tension after grooming in wild Japanese macaques (Macaca fuscata yakui) is sex specific and sensitive to social relationships
Changes in the rate of self‐directed behavior—a proxy for social tension—offer valuable insights into individuals' experiences of social interactions. Many studies have tested the tension‐reduction hypothesis, whereby grooming is expected to reduce social tension in the grooming partners. However, it is still unclear whether responses to grooming are affected by social factors such as an individual's role or social relationship with their partner…

Emotional states following grooming in female mandrills
Grooming is a common cooperative behavior whose exact costs and benefits are still to be fully elucidated. In this study, we evaluated the emotional consequences of giving and receiving grooming in mandrills ( Mandrillus sphinx ), and how these may change along time after the termination of grooming. We used scratching as a behavioral indicator of anxiety‐like emotions. Groomees showed increased scratching immediately after the termination of gro…
Anxiety in Geoffroy's spider monkeys ( Ateles geoffroyi ): Can scratching be used as an indicator
Self‐directed behavior, such as self‐scratching (hereafter, scratching), occurs in several taxa across the animal kingdom, including nonhuman primates. There is substantial evidence that scratching is an indicator of anxiety‐like emotions in a variety of nonhuman primate species. Despite its importance as a window into emotional states, few studies have investigated scratching in Platyrrhines. We investigated scratching patterns of 24 Geoffroy's …
Monitoring of group mates in relation to their behavior in mandrills
Primates are known to have considerable knowledge about the social relationships that link their group mates and are likely to derive this information from observing the social interactions that occur in their social group. They may, therefore, be hypothesized to pay particular attention to the social interactions involving group mates. In this study, we evaluated how the attention captive mandrills ( Mandrillus sphinx ) devote to their group mat…
Age‐related changes in the social behavior of tufted capuchin monkeys
The influence of phylogeny, social style, and sociodemographic factors on macaque social network structure
Among nonhuman primates, the evolutionary underpinnings of variation in social structure remain debated, with both ancestral relationships and adaptation to current conditions hypothesized to play determining roles. Here we assess whether interspecific variation in higher-order aspects of female macaque (genus: Macaca) dominance and grooming social structure show phylogenetic signals, that is, greater similarity among more closely-related species…
Factors affecting cashew processing by wild bearded capuchin monkeys ( Sapajus libidinosus , Kerr 1792)
Cashew nuts are very nutritious but so well defended by caustic chemicals that very few species eat them. We investigated how wild bearded capuchin monkeys (Sapajus libidinosus) living at Fazenda Boa Vista (FBV; Piauí, Brazil) process cashew nuts (Anacardium spp.) to avoid the caustic chemicals contained in the seed mesocarp. We recorded the behavior of 23 individuals toward fresh (N = 1282) and dry (N = 477) cashew nuts. Adult capuchins used dif…

Exchanging grooming, but not tolerance and aggression in common marmosets ( Callithrix jacchus )
In this study, we investigated the reciprocal exchanges of grooming, tolerance and reduced aggression in common marmosets (Callithrix jacchus), a cooperatively breeding primate whose groups are typically characterized by uniformly high genetic relatedness and high interdependency between group members. Both partner control and partner choice processes played a role in the reciprocal exchanges of grooming. In contrast, we did not find any evidence…
Hierarchical Steepness, Counter‐Aggression, and Macaque Social Style Scale
Nonhuman primates show remarkable variation in several aspects of social structure. One way to characterize this variation in the genus M acaca is through the concept of social style, which is based on the observation that several social traits appear to covary with one another in a linear or at least continuous manner. In practice, macaques are more simply characterized as fitting a four‐grade scale in which species range from extremely despotic…
Fitness‐related benefits of dominance in primates
Dominance hierarchies are thought to provide various fitness‐related benefits to dominant individuals (e.g., preferential access to food or mating partners). Remarkably, however, different studies on this topic have produced contradictory results, with some showing strong positive association between rank and fitness (i.e., dominants gain benefits over subordinates), others weak associations, and some others even revealing negative associations. …
Social relationships between adult females and the alpha male in wild tufted capuchin monkeys
Primates are notable for the widespread presence of long‐term female–male associations which go beyond the mating context. However, little attention has been given to the factors that affect within‐species variation in female–male relationships, especially among New World primates. Although detailed accounts of heterosexual relationships in Cebus species are scarce, a few studies have suggested the occurrence of strong associations between adult …

Primate reciprocity and its cognitive requirements
Humans can engage in relatively indiscriminate altruistic behaviors such as donating money to charities, giving blood, and volunteering to review scientific papers. They also live in societies characterized by examples of cooperation of unmatched complexity, such as organized armies, the cooperative building of infrastructures such as roads and railways, and tax-paying, among others. (We exclude, of course, the "anonymous" societies of some socia…
Grooming, rank, and agonistic support in tufted capuchin monkeys
Studies investigating the relation between allogrooming and social rank in capuchin monkeys (genus Cebus ) have yielded inconsistent results. In this study, we investigated the relation between grooming, agonistic support, aggression and social rank in a captive group of tufted capuchin monkeys ( C. apella ). Differently from most previous studies, we based our analyses on a relatively large database and studied a group with known genealogical re…
Grooming in mandrills and the time frame of reciprocal partner choice
In this study, we examined the time frame of reciprocal partner choice in the grooming interactions of captive mandrills ( Mandrillus sphinx ) in order to test the hypothesis that the cognitive limitations of primates constrain the occurrence of reciprocation to short time intervals. In contrast to this hypothesis, mandrills groomed preferentially those individuals that groomed them more even when cases of immediate reciprocation were excluded fr…
Reciprocation and interchange in wild Japanese macaques: Grooming, cofeeding, and agonistic support
Social primates spend a significant proportion of their time exchanging grooming with their group companions. Although grooming is mainly exchanged in kind, given its hygienic and tension‐reducing functions, it is still debated whether grooming also provides some social benefits, such as preferential access to resources (e.g., food or mating partners). In this study we analyzed grooming distribution among wild female Japanese macaques living in t…

Differential effects of ambient temperature and humidity on allogrooming, self-grooming, and scratching in wild Japanese macaques
This study presents data on the effects of variations in ambient temperature and humidity on behaviors related to the care of the pelage (allogrooming, self-grooming, and scratching) in wild Japanese macaques (Macaca fuscata yakui). The amount of time monkeys spent allogrooming was essentially unaffected by variations in ambient temperature and relative humidity. Frequency of scratching and, to a lesser extent, time spent self-grooming significan…

Neonatal abandonment in Japanese macaques
This study analyzed long-term demographic data relative to a captive colony of Japanese macaques (Macaca fuscata) in order to evaluate factors predicting increased probability of infant neonatal abandonment. Overall, 7.7% of liveborn infants were abandoned at birth. Probability of abandonment was significantly increased in primiparous and, to a lesser extent, low-ranking mothers. Primiparous mothers abandoned about 40% of their infants at birth. …

Allogrooming as a tension‐reduction mechanism: A behavioral approach
The hypothesis that allogrooming functions as a tension‐reduction mechanism was tested. Tension was measured by the frequency of displacement activities by an animal. Two adult male and 11 adult female Java (or long‐tailed) monkeys ( Macaca fascicularis ) that were relatively unfamiliar with each other were paired 1 hour per day for five consecutive days during the periovulatory portion of the menstrual cycle. Female allogrooming was found to red…

Infant kidnapping and co‐mothering in Japanese macaques
The fatal kidnapping of a Japanese macaque infant is described. Kidnapping was followed by a long period (10 weeks) of co‐mothering. Quantitative recording showed that both the biological mother (a 8‐year‐old, low‐ranking, multiparous female) and the kidnapper (a 4‐year‐old, high‐ranking female with no maternal experience) displayed an affectionate style of mothering and never responded negatively to the infant's demands for contact. Given the la…
