Simulation of leaf grooming as play by infant wild chimpanzee
This article reports a new finding of a simulation of leaf grooming behavior as a form of play by an infant chimpanzee in Mahale, Tanzania. Leaf grooming, typically associated with external parasite removal, is a common behavior customary observed in M group chimpanzees in Mahale. However, the acquisition of this behavior by inexperienced individuals remains poorly understood. 3.5 year-old infant female chimpanzee, KP20, was observed simulating l…
Epidemiological Consequences of Individual Centrality on Wild Chimpanzees
Disease outbreaks are one of the key threats to great apes and other wildlife. Because the spread of some pathogens (e.g., respiratory viruses, sexually transmitted diseases, ectoparasites) are mediated by social interactions, there is a growing interest in understanding how social networks predict the chain of pathogen transmission. In this study, we built a party network from wild chimpanzees ( Pan troglodytes ), and used agent‐based modeling t…
Diet‐related factors strongly shaped the gut microbiota of Japanese macaques
Although knowledge of the functions of the gut microbiome has increased greatly over the past few decades, our understanding of the mechanisms governing its ecology and evolution remains obscure. While host genetic distance is a strong predictor of the gut microbiome in large‐scale studies and captive settings, its influence has not always been evident at finer taxonomic scales, especially when considering among the recently diverged animals in n…
Waza on the Move ou l'art ineffable de l'apprentissage
Image d’ouverture. Les waza des cuisiniers et de la dessinatrice en dialogue Cliché représentant Aurélia Aurita, dessinatrice de bandes dessinées, pris au cours d’une enquête anthropographique menée à Marseille, en décembre 2019, dans le restaurant du chef étoilé Alexandre Mazzia. Sur le vif, elle capte les situations et les gestes de l’art culinaire, mais les met aussi en couleur. Épure et stylisation vont étrangement de pair avec le souci d’aut…
Jeu, objets, outils et apprentissage chez les chimpanzés sauvages
Les chimpanzés (Pan troglodytes) font partie des espèces animales les plus proches de l’humain sur le plan phylogénétique. Une étude de terrain à long terme, menée pendant plus d’un demi-siècle sur les chimpanzés sauvages du groupe M dans le Parc national des monts Mahalé en Tanzanie (Mahalé), a révélé que les chimpanzés et les humains ont en commun de nombreux comportements longtemps attribués aux seuls humains, parmi lesquels l’utilisation d’ou…

Social play among juvenile wild Japanese macaques ( Macaca fuscata ) strengthens their social bonds
Social play and grooming are typical affiliative interactions for many primate species, and are thought to have similar biological functions. However, grooming increases with age, whereas social play decreases. We proposed the hypothesis that both social grooming and social play in juveniles strengthen their social bonds in daily activities. We carried out field research on the social relationships among juvenile wild Japanese macaques in a troop…

Is ☺ Smiling? Cross-Cultural Study on Recognition of Emoticon's Emotion
Emoticons are getting more popular as the new communication channel to express feelings in online communication. Although familiarity to emoticons depends on cultures, how exposure matters in emotion recognition from emoticon is still open. To address this issue, we conducted a cross-cultural experimental study among Cameroon and Tanzania (hunter-gatherers, swidden farmers, pastoralists, and city dwellers) wherein people rarely experience emotico…
The importance of social play network for infant or juvenile wild chimpanzees at Mahale Mountains National Park, Tanzania
Along with social grooming and food sharing, social play is considered to be an affiliative interaction among wild chimpanzees. However, infant, juvenile, and adolescent animals engage in social play more frequently than adult animals, while other affiliative interactions occur more commonly between adults. We studied the social play of well-habituated and individually identified wild chimpanzees of the M group in Mahale Mountains National Park, …

Case study of a one‐sided attack by multiple troop members on a nontroop adolescent male and the death of Japanese macaques ( Macaca fuscata )
An adolescent wild male Japanese macaque ( Macaca fuscata ), following Kinkazan A troop, was attacked one‐sidedly by multiple members of the troop. The victim was identified as PI, and was estimated to be seven±one year old. The aggressive interaction was recorded by video camera until the end. Although at least 16 troop members approached PI more than once, only three males (one adult, two adolescents) of A troop attacked him. PI kept crouching …
