This leads to cell apoptosis, amyloid beta accumulation, and tau hyperphosphorylation, all hallmarks of Alzheimer's disease and related dementias (ADRD). Baboons show neurological hallmarks of ADRD, including age-dependent tau pathology in neurons and glial cells, cerebral amyloid beta (Aβ) deposit-associated microvascular degeneration, and age-related increases in neurodegenerative and neuroinflammatory biomarkers. Here, we aim to characterize biomarkers of metabolic function according to age, sex, rearing, and obesity in captive olive baboons. We also examined associations between metabolic biomarkers (MBs) and biomarkers related to neurodegeneration (ND) and neuroinflammation (NI) (together, referred to NDNIBs) as well as between MBs and a behavioral indicator of aging and metabolic health (walking speed). We collected plasma in 133 baboons and cerebrospinal fluid (CSF) in 44 baboons, and recorded walking speeds in 128 baboons. For both NDNIB and MB, we calculated load scores using quartiles, and deviation scores using z-scores, where higher scores indicated higher biomarker levels and greater deviation from the mean, respectively. There were few significant differences across MBs as a function of age, sex, and rearing, and no differences as a function of obesity status. However, higher MB load scores were correlated with greater NDNIB deviation scores in CSF. Additionally, MB deviation scores predicted walking speeds. These data support previous studies showing that higher metabolic dysfunction is associated with greater concurrent burden of neurodegenerative indicators in nonhuman primates.","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 5","pages":"e70168"},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13288330/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148013131","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}

Apart from the inherent interest in the demographic dynamics of this abundant platyrrhine native to the Amazon forest of Brazil and Peru, this quantification will also serve as a central component of future genotype-to-phenotype studies, given the ability of historical population size change and structure to generate genetic associations. In this study, we deep-sequenced the genomes of six unrelated individuals and inferred a baseline demographic model based on observed levels and patterns of variation in the non-coding regions of the genome. In characterizing these demographic dynamics, we found that estimated population size changes correspond well to previously described speciation times in the genus as well as to large-scale climatic changes relating to glaciation patterns.","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 5","pages":"e70166"},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13419261/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148013106","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}

Identifying how habitat loss affects wildlife, particularly vulnerable populations, is important to understand the mechanisms that can lead to population decline. Golden monkeys are a subspecies of guenon with two extant populations: one larger (> 4000) on the Virunga Massif, and the other smaller (~200) in Gishwati Forest. Once connected, deforestation over five decades separated the forests of Volcanoes National Park (VNP) (on the Virunga Massif) and Gishwati Forest and decreased the total forest cover by 25 and 90 percent, respectively. It is likely that the golden monkey populations also decreased during that time. We examined how location (VNP vs Gishwati) and human contact (low vs. high) affected infection using records of parasites identified morphologically from feces. We assessed the effect of population or human contact (via crop foraging or distance to forest edge) and used a mixed model to explore if there was an interaction effect between population and human contact (i.e., distance to forest edge). Both populations had the same richness. Overall, the VNP monkeys had A higher prevalence of infection and higher rates of multiple infection and groups that foraged for crops or were near the forest edge had a higher prevalence of Capillaria infection. These results suggest that population density, forest edge permeability, and human presence outside the forest increase infection risk in golden monkeys. Further, they provide initial insights into parasite-based health risks for this endangered primate.","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 5","pages":"e70158"},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147832592","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}

Among primates, several factors, like sociality and diet, have been found to be important in structuring the gut microbiota. The relative importance of sociality versus diet has yet to be examined for bonobos (Pan paniscus). Here, we describe dietary, social, and gut microbiota data for 252 bonobo fecal samples collected from June to October 2017 at Iyema, Lomako forest, Democratic Republic of Congo. DNA was extracted, 16S rRNA libraries were prepped, and samples were sequenced on an Illumina MiSeq run sequences were then paired with nesting group dynamics and feeding behavior data. We found that the Lomako forest bonobo gut microbiota alpha diversity was statistically significantly explained by nesting party (a measure of party membership), the number of nests (a measure of party size), and month (a measure of seasonality). Nesting party explains 19.48%-20.28% of beta diversity in bonobo gut microbiota for Bray-Curtis dissimilarity metrics and 17.06%-21.38% for Aitchison's distance. Our generalized dissimilarity model results found that sociality variables, like geographic distance, explained the most variation compared to dietary variables. These results suggest that sociality may be particularly important in structuring the gut microbiota in the Lomako forest bonobos. Sociality may therefore be more informative than diet when examining the co-evolutionary history of microbes and their hosts in hominoids.","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 5","pages":"e70162"},"PeriodicalIF":1.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13178060/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147947539","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}
