Non-invasive measures of DNA methylation capture molecular aging in wild capuchin monkeys

This study shows that DNA methylation from fecal samples accurately reflects molecular aging in wild capuchin monkeys, revealing age-related epigenetic changes linked to cellular damage and inflammation.

Sources of Variation in Fecal Haptoglobin in a Population of Wild Capuchin Monkeys (Cebus imitator)

This study validates fecal haptoglobin as a biomarker of inflammation in wild capuchin monkeys and finds environmental factors, not demographic or circadian variables, influence its concentrations.

Fecal proteomics of wild capuchins reveals impacts of season, diet, age, and, sex on gut physiology

This study uses fecal proteomics to show how season, diet, age, and sex affect gut physiology in wild capuchins.

Specialized for the reach: Fruit picking and positional behavior favor a reach over a grasp phenotype for Geoffroy's spider monkey (Ateles geoffroyi )

This study examines how Geoffroy's spider monkeys use their morphology to forage for fruit, finding a 'reach' phenotype characterized by branch-withdraw strategies and prehensile tail use, contrasting with capuchin monkeys' 'grasp' phenotype.

Distinct gene regulatory signatures of dominance rank and social bond strength in wild baboons

This study identifies gene regulatory differences linked to dominance rank and social bond strength in wild baboons, showing sex-specific effects and distinct immune responses to social factors.

The costs of competition: high social status males experience accelerated epigenetic aging in wild baboons

This study finds that high-ranking male baboons show accelerated epigenetic aging, suggesting a trade-off between reproductive success and lifespan.
