In all cases, the former is defined as a kind of hierarchical nesting and the latter as a lack thereof. In this article, I extend research on combinatoriality and compositionality further to investigations of everyday primate skills. Daily locomotion modes as well as behaviors associated with subsistence practices, hygiene, or body modification rely on the hierarchical nesting of different behavioral and cognitive actions into complex skills. I introduce a scheme which uses hierarchical organization to differentiate combinatorial from compositional skills. Combinatorial skills are defined either as aggregational or linearly hierarchical depending on whether the skill occurs momentarily in space or unfolds sequentially over time. Compositional skills are defined either as nested or interactionally hierarchical depending on whether the skill results in new constructs or in new interactions between existing constructs. The methodology I propose combines epistemological hierarchy theory with data from primatological field research and experimental and comparative psychological research and provides a means to integrate current constructionist and extended views on cognition and action with older research on behavioral logics in psychology and operational chain thinking in anthropology. The approach furthermore synchronizes with ongoing research on teleonomy, intentionality, and creativity.</p>","PeriodicalId":14264,"journal":{"name":"International Journal of Primatology","volume":"24 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139750572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nature and frequency of play are expected to change accordingly over the developmental trajectory and with socio-ecological context. Orangutans offer the opportunity to disentangle the ontogenetic trajectories of solitary and social play with their extended immature phase, and socio-ecological variation among populations and species. We evaluated the frequency of play in 39 immature individuals across two populations (<em>Pongo pygmaeus wurmbii</em>, at Tuanan, Borneo, and <em>P. abelii</em> at Suaq, Sumatra), age (0–11 years), sex, and social context, using more than 11 500 h of full-day focal observation data. We found independent age trajectories of different play types, with solitary object and solitary locomotor peaking before social play. Social play partners changed during ontogeny, and male immatures were more likely to engage in non-mother social play than females. Overall, social play was more frequent at Suaq than Tuanan, linked to the more frequent availability of partners. Furthermore, per time in association with conspecifics, Tuanan immatures were as likely to engage in social play as their peers at Suaq, suggesting similar intrinsic motivation. Increasing fruit availability correlated with both longer associations and increased social play frequency in the less sociable population of Tuanan, but not at Suaq. Our findings on orangutans support evidence from other species that different play types follow different developmental trajectories, vary with sex, social opportunities, and ecological context. Although drawing functional inferences is challenging, the distinct developmental trajectories reflecting adult sociability and behavioral repertoires may indicate that play serves several, non-mutually exclusive functions during ontogeny.</p>","PeriodicalId":14264,"journal":{"name":"International Journal of Primatology","volume":"28 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139506156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process of identifying suitable release sites involves finding areas with adequate resources and minimizing negative impacts on resident species and human populations. To address this challenge, this study was designed to identify and map suitable areas for the reintroduction of bearded capuchin monkeys (<i>Sapajus libidinosus</i>) into the Caatinga biome in northeastern Brazil. We used a multicriteria decision analysis (MCDA) to identify suitable release areas. Using a species distribution model, we located suitable habitats for seven species of vegetation that are vital resources during the dry season: <i>Syagrus romanzoffiana</i>, <i>Attalea speciosa</i>, <i>Syagrus oleracea</i>, <i>Commiphora leptophloeos</i>, <i>Manihot epruinosa</i>, <i>Pilosocereus pachycladus</i>, and <i>Tacinga inamoena</i>. We then created an MCDA by using vegetation suitability, water availability, proximity to protected areas, and distance from roads and cities as key variables. To increase accessibility, we coded the results into a Google Earth Engine app, allowing for easy and free access to researchers and others interested in capuchin monkey conservation. The resulting suitability maps cover the entire Caatinga biome, providing a valuable tool for conservation efforts by simplifying the initial step of locating potential release sites. This study demonstrates the application of geospatial tools in mapping suitable habitats for the translocation and release of rehabilitated primates at a time when biodiversity loss, the exotic pet trade, land use change, and climate change are threatening nonhuman primates worldwide.</p>","PeriodicalId":14264,"journal":{"name":"International Journal of Primatology","volume":"7 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139483328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their social interactions reflect intraspecific interactions, social bonding, rank, reproductive status, and relatedness. Titi monkeys (<i>Callicebus, Cheracebus</i>, and <i>Plecturocebus</i>) are a diverse group of pitheciid primates that are widely distributed throughout South America. Typically, they live in small groups composed of a breeding pair and their offspring. Although social structure and interactions have been studied in captive titi monkeys, there has been much less research on free-ranging groups. We used all occurrence sampling during a 16-month period to investigate group composition and within-group social interactions in five wild groups of black-fronted titi monkeys, <i>Callicebus nigrifrons</i> living in an Atlantic Forest fragment at the Caraça Private Natural Heritage Reserve in Minas Gerais, Brazil. Unusually for the species, we found more than one adult male in three of our study groups (three adult males in one group and two in the other two groups). As reported for other titi monkeys, the breeding pair interacted more with each other than with any other group members. We also observed that breeding males interacted more with their offspring than breeding females did. Our results expand the existing literature on the social structure of titi monkeys, demonstrating their flexible social organization, providing further evidence of the breeding pair as the nucleus of the group and showing evidence for strong paternal care and stable attachments between breeding pairs in free-ranging <i>C. nigrifrons</i>.</p>","PeriodicalId":14264,"journal":{"name":"International Journal of Primatology","volume":"83 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139067795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

People older than 50 years with a university degree and/or a profession had higher levels of knowledge about diet than younger people without it. We found no effect of whether tourists came from regions with or without monkeys as native fauna or sex on tourists’ levels of knowledge. Most of the tourists believed that monkeys approach people because they are looking for food. Taking photos, curiosity, and feeding monkeys were the most important reasons given for why people approach the monkeys.

We found significant increases in rainfall, ambient temperature, and food availability in summer compared with winter. However, we found no significant changes in body mass or in the overall diversity of bacterial species present in fecal samples between the two seasons. We found significant decreases in the abundance of certain bacterial families in winter, suggesting a change in diet. Our findings suggest that greater thick-tailed galagos can find food resources to maintain their body mass throughout the year.
