It is possible that other extant primate species may show a similar response to the presence of plants, but direct experimental interventions on indoor-housed primates, with plants isolated as a variable, represent a gap in the literature. In this study, 20 coppery titi monkeys (Plecturocebus cupreus) housed indoors were exposed to foliage outside of their home cages. Behavior following introduction to plants was recorded and compared to behavior following baseline and control object conditions. The addition of both the plant and control object was associated with a decrease in stereotypic behaviors and an increase in affiliative behavior between bonded mates compared to baseline. The addition of the live plant was associated with increased grooming, and monkeys spent significantly more time looking at the live plant compared to the control object. The reduction in stereotypic behaviors and increase in affiliative behaviors provide support for plants as a potential enrichment strategy. The increase in grooming, combined with greater visual attention to plants, suggests that titi monkeys may have an evolutionary affinity towards plants.","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 5","pages":"e70163"},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13169095/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147925485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I argue that such conclusions are unwarranted. First, the human FFM contains facets-such as aesthetics, ideas, values, modesty, dutifulness, deliberation, and more-that have not been convincingly detected in animals. Second, I show that great ape personality traits are not structured like their postulated human FFM/Big Five equivalents. Based on very relaxed criteria, the shared invariant structure (percentage of indicators with the highest loadings consistently on the same factor) in humans and great apes is just below half at best and often only about one-third. Great ape personality models are not structured equivalently either, suggesting that each species has its own personality structure. Even FFM/Big Five-based studies of the same species do not yield invariant models. Consequently, neither the whole human FFM/Big Five nor its dimensions separately are appropriate for nonhumans. I propose that personality comparisons across species can be made more judiciously by focusing on approximations of single and simple human FFM facets (rather than whole complex traits) whose rough equivalents have been confirmed across all great apes, and some prototypes of which have emerged even in studies of cephalopods. This approach could allow meaningful comparisons of personality across species.","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 5","pages":"e70153"},"PeriodicalIF":1.8,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831847","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}

Given the threats to the health and well-being of both humans and non-human primates, more attention is needed to this topic. By comparing the infection status of zoonotic pathogens in primate populations with contrasting levels of human interaction, we can better understand the relationship between human-primate contact and the prevalence of pathogens. To this end, we collected fecal samples from two Taiwanese macaque (Macaca cyclopis) populations in southern Taiwan: Shoushan National Nature Park (Kaohsiung), characterized by extremely high human interface, and the Dahan Forest Trail (Pingtung), characterized by very low human interface. These samples were molecularly screened for Helicobacter pylori, four common pathogenic Campylobacter species, and four gastrointestinal zoonotic parasites (Strongyloides fuelleborni, Oesophagostomum aculeatum, Entamoeba coli, and Entamoeba chattoni). In both populations, the prevalence rates of H. pylori and the two amoebic protozoa were quite high (exceeding 70%), while Campylobacter and the two nematodes ranged between 10% and 20% of samples. The Shoushan high-interface macaques were infected with pathogenic Campylobacter coli (detected in four samples from that site), whereas a higher sample prevalence of Campylobacter (genus) and O. aculeatum was found in the low-interface Dahan population. Our findings highlight that even macaque groups with minimal human contact harbor significant zoonotic pathogens, whereas highly provisioned groups can acquire human-associated bacteria, underlining the importance of managing human-primate interactions to mitigate bidirectional disease transmission risks.","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 5","pages":"e70159"},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147831777","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}

Experimental tasks requiring the simultaneous and coordinated use of both hands induce hand preferences at the population level across various nonhuman primate species studied in captive environments. However, to date, research investigating laterality in bimanual coordination within natural settings remains scarce, especially with respect to platyrrhine taxa. We assessed hand preference in a bimanual coordinated extractive foraging task by wild bearded capuchin monkeys, Sapajus libidinosus, living in the Cerrado/Caatinga ecotone, Northeast Brazil. Nineteen individuals were filmed during the consumption of four different nut species for 4 months. A detailed video-coding analysis was conducted on their hand movements to extract the edible kernel(s) from the nuts. Overall, most individuals were lateralized, and as a group, capuchins significantly preferred their right-hand fingers for extracting the kernel, thus suggesting an advantage of the left hemisphere for fine finger movements. The comparison with captive capuchins previously tested with an experimental bimanual coordinated task (the tube task), revealed that the direction of the preference did not differ between wild and captive individuals, although the latter tended to use their preferred hand more consistently. Our findings are in line with a growing body of evidence suggesting that bimanual coordination might have played a major role in the evolution of limb preference for motor action in primates and indicate that the study of coordinated bimanual behaviors in natural settings provides a valuable contribution to the understanding of manual laterality.","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 5","pages":"e70165"},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13181520/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147962045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sarcopenia progression in humans is highly correlated with various pathologies and mortality risks independent of other risk factors. Laboratory-housed non-human primates that do not engage in adequate physical activity are at higher risk of developing sarcopenia. We devised a simple behavioral task to enhance environmental enrichment and increase physical fitness. An aperture allowed vertical movement between two vertically mounted cages. Despite this arrangement, male cynomolgus macaques (approximately 13 years old) still spent the majority of time in the upper cage and were not very active. Therefore, we implemented a new behavioral method using sweetened liquid as a reinforcer. Monkeys could initiate each trial by pressing the touch screen in the upper cage which would light a large red button placed in the lower cage. Pressing the button resulted in immediate delivery of juice in the upper cage for 5 s; thus, the monkey was encouraged to rapidly ascend to the top cage to drink as much of the liquid reinforcer as possible. Increases in exercise behavior (measured via operant testing apparatus and real-time monitoring) and activity (measured via actigraphy monitors) suggest that this highly adaptable method successfully increases strenuous exercise and species-typical climbing behavior, and can potentially provide a novel means of measuring and promoting physical and psychological well-being, as well as potentially attenuating sarcopenia in laboratory-housed primates.","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 5","pages":"e70160"},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147832623","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}

We focused on four species (Colobus guereza, Colobus angolensis, Trachypithecus cristatus, and Trachypithecus francoisi) housed across 20 AZA-accredited institutions and integrated detailed dietary records with fecal microbiome profiling. Diets were categorized using Partition Around Medoids clustering based on macronutrient content, while browse offerings were classified by provisioning frequency (low, moderate, and high). Microbial diversity and community composition were evaluated using high-throughput 16S rRNA sequencing. The results revealed that browse provisioning frequency was the strongest predictor of microbiome alpha diversity, with moderate and high browse categories supporting significantly greater microbial richness and evolutionary breadth than low browse frequency. While diet cluster and phylogeny did not significantly affect alpha diversity metrics, all three factors significantly influenced the overall microbiome composition, as indicated by the unweighted and weighted UniFrac analyses. Notably, diet clusters with the highest relative crude fat (16.33%) or protein (23.27%) content, as well as sugar-rich diets promoted distinctive shifts in microbial community structure and function, fostering bacteria linked to dietary macronutrient processing, and in low-fiber contexts, reduce the abundance of key fiber-degrading taxa. These findings emphasize the necessity of frequent browse provision and an appropriate fiber balance to maintain gut microbial diversity and ecosystem stability in zoo-housed colobines. These results provide evidence-based recommendations for husbandry practices to promote nutritional and microbiome health in managed primate populations.","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 5","pages":"e70169"},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148025615","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}
