Hard-Object Feeding in Sooty Mangabeys (Cercocebus atys) and Interpretation of Early Hominin Feeding Ecology [PDF]
PLoS ONE, 2011 Morphology of the dentofacial complex of early hominins has figured prominently in the inference of their dietary adaptations. Recent theoretical analysis of craniofacial morphology of Australopithecus africanus proposes that skull form in this taxon ...

Social uncertainty promotes signal complexity during approaches in wild chimpanzees (Pan troglodytes verus) and mangabeys (Cercocebus atys atys) [PDF]
Royal Society Open Science, 2023 The social complexity hypothesis for the evolution of communication posits that complex social environments require greater communication complexity for individuals to effectively manage their relationships.

Vocal sequence diversity and length remain stable across ontogeny in a catarrhine monkey (Cercocebus atys) [PDF]
Communications BiologyDuring childhood, human speech utterances increase steadily in complexity, length and diversity. In contrast, the vocal repertoire of non-human primates has long been considered fixed from birth.

How mangabey molar form differs under routine vs. fallback hard-object feeding regimes [PDF]
PeerJ, 2023 Background Components of diet known as fallback foods are argued to be critical in shaping primate dental anatomy. Such foods of low(er) nutritional quality are often non-preferred, mechanically challenging resources that species resort to during ...

Vocal correlates of individual sooty mangabey travel speed and direction [PDF]
PeerJ, 2016 Many group-living animals coordinate movements with acoustic signals, but so far most studies have focused on how group movements are initiated. In this study, we investigated movement patterns of wild sooty mangabeys (Cercocebus atys), a mostly ...

Mechanical adaptation of trabecular bone morphology in the mammalian mandible [PDF]
Scientific Reports, 2018 Alveolar bone, together with the underlying trabecular bone, fulfils an important role in providing structural support against masticatory forces. Diseases such as osteoporosis or periodontitis cause alveolar bone resorption which weakens this structural

Turn-taking in grooming interactions of sooty mangabeys (Cercocebus atys) in the wild [PDF]
Animal CognitionLanguage is widely regarded as a uniquely human trait, rooted in mechanisms of social interaction such as conversational turn-taking. It has been proposed that turn-taking may not be exclusive to humans but may represent an ancestral trait shared across ...

Simian immunodeficiency virus and storage buffer: Field-friendly preservation methods for RNA viral detection in primate feces [PDF]
mSphere, 2023 Wild non-human primates carry many types of RNA viruses, including simian immunodeficiency virus (SIV), simian foamy virus, simian T-cell leukemia virus, and hepatitis C virus.

Downclimbing and the evolution of ape forelimb morphologies [PDF]
Royal Society Open Science, 2023 The forelimbs of hominoid primates (apes) are decidedly more flexible than those of monkeys, especially at the shoulder, elbow and wrist joints. It is tempting to link the greater mobility of these joints to the functional demands of vertical climbing ...

Call combination order and iterations may shift meaning in sooty mangabey vocal sequences [PDF]
BMC BiologyBackground Human language expands meaning through the structured combination of sounds, but such mechanisms remain rare in nonhuman animals, raising questions about their evolution.
