Reciprocation and interchange in wild Japanese macaques: grooming, cofeeding, and agonistic support
Results suggest that monkeys may derive various social benefits from grooming, and are supported by the fact that in various primate species animals tend to prefer high‐ranking individuals as grooming partners. Expand
Infant Handling and Maternal Response in Japanese Macaques
We focused on the social interactions of infant Japanese macaques (Macaca fuscata) and on the protective response of their mothers to such interactions. Infant social interactions included: receivedExpand
Asymmetry and Dimensions of Relationship Quality in the Japanese Macaque (Macaca fuscata yakui)
Cords and Aureli (2000) proposed that relationship quality can be described by three components, i.e., value, security, and compatibility, based on the benefits social partners receive from theirExpand
Postconflict Behavior Among Male Japanese Macaques
Differences in the behavioral ecology of the 2 subspecies, the ecological and social factors that may favor the occurrence of reconciliation, and the possible benefits that males gain from grooming exchange and reconciliation are discussed. Expand
Grooming among female Japanese macaques: distinguishing between reciprocation and interchange
The results suggest that the use of the temporal patterning of grooming to distinguish the different classes of traders predicted by the theory is unsuccessful. Expand
Sex, rank and age differences in the Japanese macaque (Macaca fuscata yakui) participation in inter-group encounters
Data indicate that in non-territorial species with male dominance over female and high competition for mating partners males play an active, and often aggressive, role during inter-group encounter while female participation is scarce. Expand
Analysing the effects of group size and food competition on Japanese macaque social relationships
The results indicate that social relationships within the two groups were the result of the combination of group size differences and of the balance between the benefits and costs of a lower/greater level of inter- and intra-group food competition. Expand
Apparent feeding association between Japanese macaques (Macaca fuscata yakui) and sika deer (Cervus nippon) living on Yakushima Island, Japan
The results suggest that deer gain some benefits by this behaviour while they apparently do not inflict any costs to monkeys, and interactions between sika deer and Japanese macaques may represent a case of commensalism, or of asymmetrical mutualism. Expand
Anxiety Level Predicts Post-Conflict Behaviour in Wild Japanese Macaques (Macaca fuscata yakui)
Reconciliation (i.e. the post-conflict exchange of friendly behaviour between former opponents) functions to control for the detrimental effects that aggression may have on social relationships.Expand
A Statistical Modelling Approach to the Occurrence and Timing of Reconciliation in Wild Japanese Macaques
In various social species, animals have been observed to share friendly relationships with some group members and to resolve conflicts through reconciliation, the exchange of affiliative behaviourExpand
