Leadership Under Risk: Male Vervet Monkeys' (Chlorocebus pygerythrus) Roles in Group Progression Across Potentially High‐Risk Terrain

Ethology, Volume 132, Issue 8, Page 544-556, August 2026.
Male vervet monkeys were more likely to lead group progressions than females or juveniles, especially during potentially riskier crossing situations, i.e., rivers. Dominant males who had not yet sired offspring were the most likely to lead progressions.

CD49a expression defines a metabolically robust, cytokine‐biased liver NK cell subset in rhesus macaques during lentivirus infection

Immunology &Cell Biology, Volume 104, Issue 7, Page 656-666, August 2026.
Liver‐resident NK cells (CD49a+ NK cells) in rhesus macaques display distinct activating receptor and metabolic markers enhanced phenotype compared with hepatic NK cell subsets (CD49a−) in the liver. These cells exhibit heightened cytokine polyfunctionality with restrained cytotoxic responses upon mitogen stimulation in comparison with CD49a− NK cell ...

Automated face recognition of rhesus macaques

Journal of Neuroscience Methods, 2018
Rhesus macaques are widely used in biomedical research. Automated behavior monitoring can be useful in various fields (including neuroscience), as well as having applications to animal welfare but current technology lags behind that developed for other species.

Clinical Management of Helicobacter Infection in Captive Baboons (Papio anubis and Papio hamadryas), and Isolation and Molecular Characterization of Three Novel Helicobacter Species

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT Background Helicobacter spp. are gastric or enterohepatic bacteria that can be commensal, opportunistic, or pathogenic. Few studies have evaluated Helicobacter spp. in baboons. Methods Twenty‐seven captive baboons were surveyed for Helicobacter spp. by fecal PCR, and a subset evaluated by culture.

Multifocal Oral Epithelial Hyperplasia Associated With Papillomavirus Infection in a Road Killed Brown Howler Monkey (Alouatta guariba clamitans)

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT A free‐ranging road‐killed brown howler monkey (Alouatta guariba clamitans) presented multiple mucosal‐colored papules and plaques on oral mucosa. Pathological evaluation confirmed the diagnosis of epithelial hyperplasia with koilocytosis.

Does ulnar curvature covary with locomotion and substrate use in cercopithecids?

Journal of Anatomy, Volume 249, Issue 2, Page 383-400, August 2026.
This study investigates ulnar curvature in cercopithecids in relation to locomotor behaviors, introducing an analysis of anteroposterior and mediolateral curvature, using geometric morphometric on 167 specimens (23 species). Although the two curvatures distinguish arboreal and terrestrial quadrupeds, their moderate covariation suggests that they ...

The phylogenetic relationship and demographic history of rhesus macaques (Macaca mulatta) in subtropical and temperate regions, China

Ecology and Evolution
Pleistocene climatic oscillations exerted significant influences on the genetic structure and demography of rhesus macaque (Macaca mulatta) in eastern China. However, the evolutionary history of rhesus macaques in subtropical and temperate China remained

Evolutionary and biomedical implications of sex differences in the primate brain transcriptome

Cell Genomics
Summary: Humans exhibit sex differences in the prevalence of many neurodevelopmental disorders and neurodegenerative diseases. Here, we generated one of the largest multi-brain-region bulk transcriptional datasets for the rhesus macaque and characterized

Social Behavior in Aged Rhesus Macaques

Collegium antropologicum, 2003
This study investigated the relationship between chronological age and social behavior in 42 adult male and female rhesus macaques (Macaca mulatta) in three specific areas: social interactions, social roles, and social networks. While both old males and old females share behavioral differences associated with senescence, this study reports that old ...
