Enamel Prism Angle Variation and Hard-Object Feeding in Cercopithecoids With Known Diets. [PDF]
Am J Biol AnthropolLeft: Cercocebus atys specimen 16–9 third molar showing Phase II enamel prism angle (angle between prism path and wear facet) and wear angle (angle between wear facet and enamel dentin junction (EDJ)). Scatterplot of prism vs. wear angles for the Phase II wear facet. Note the higher angles for Cercocebus.

Helicobacter Species Identified in Captive Sooty Mangabeys (Cercocebus atys) with Metastatic Gastric Adenocarcinoma. [PDF]
Helicobacter, 2016 AbstractBackgroundOf all human cancers, gastric carcinoma is the one of the leading causes of death. Helicobacter pylori is considered a major etiologic agent of this disease. Spontaneously occurring gastric carcinoma is a rare diagnosis in nonhuman primates. A 2011 case report documented a high incidence of gastric adenocarcinoma in a closed colony of

Impact of dominance rank specification in dyadic interaction models.
PLoS ONE, 2023 Dominance rank is a vital descriptor of social dynamics in animal societies and regularly used in studies to explain observed interaction patterns. However, researchers can choose between different indices and standardizations, and can specify dyadic ...

Consistency of Social Interactions in Sooty Mangabeys and Chimpanzees
Frontiers in Ecology and Evolution, 2021 Predictability of social interactions can be an important measure for the social complexity of an animal group. Predictability is partially dependent on how consistent interaction patterns are over time: does the behavior on 1 day explain the behavior on

Inter-Observer Processing and Measurement Error Are Low for 2D Dental Measurements on Shared microCT Scans. [PDF]
Am J Biol AnthropolABSTRACT Objectives Sharing micro‐computed tomographic (μCT) scans of teeth increases data accessibility and reduces the need for repeated scans of any given specimen. However, the use of the same TIFF stacks or DICOMs by multiple individuals has the potential to introduce new sources of error.

Jaw-Muscle Structure and Function in Primates: Insights Into Muscle Performance and Feeding-System Behaviors. [PDF]
Evol AnthropolABSTRACT The jaw‐adductor muscles drive the movements and forces associated with primate feeding behaviors such as biting and chewing as well as social signaling behaviors such as wide‐mouth canine display. The past several decades have seen a rise in research aimed at the anatomy and physiology of primate chewing muscles to better understand the ...

Serosurveillance of Leishmania infantum in Zoo-Kept Animals in Spain. [PDF]
Zoonoses Public HealthABSTRACT Introduction Leishmaniosis is a sand fly‐borne zoonosis mainly caused by Leishmania infantum in Europe. Exposure to this protozoan has been widely reported in many domestic and wild species. However, epidemiological surveys evaluating the circulation of L. infantum in zoo‐kept animals remain limited. This large‐scale study aims to evaluate the

Hepatoma in a Mangabey (Cercocebus atys) [PDF]
Veterinary Pathology, 1973 A male sooty mangabey that died suddenly had a tumor that had metastasized to the lung and omentum. The tumor was composed of well-differentiated epithelial cells that were similar to normal hepatic parenchymal tissue. It was diagnosed as a hepatoma.

Bystanders intervene to impede grooming in Western chimpanzees and sooty mangabeys [PDF]
Royal Society Open Science, 2017 Grooming interactions benefit groomers, but may have negative consequences for bystanders. Grooming limits bystanders' grooming access and ensuing alliances could threaten the bystander's hierarchy rank or their previous investment in the groomers.

Flexible decision-making in grooming partner choice in sooty mangabeys and chimpanzees [PDF]
Royal Society Open Science, 2018 Living in permanent social groups forces animals to make decisions about when, how and with whom to interact, requiring decisions to be made that integrate multiple sources of information.
