Taxonomic and sex differences in sagittal cresting among gracile and robust capuchin monkeys. [PDF]

J Anat
In this study, I show that there are interspecific differences in the frequency and pattern of sagittal cresting among six capuchin species. Four of the six species show sagittal cresting, with Cebus capucinus showing a different sagittal cresting pattern to that observed in three robust capuchin species. All four crested species show sexual dimorphism

Meat Acquisition Skill and Male Reproductive Success in Guinea Baboons. [PDF]

Am J Biol Anthropol
ABSTRACT Objectives In human foraging societies, hunting skill is often interpreted as a signal of male quality linked to reproductive success through his ability to provision his family and community. Similarly, in some bird and insect species, males offer mates food to indicate their quality as a provider.

Contexts of Anointing Behavior in a Group of Blond Capuchin Monkeys (Sapajus flavius) Inhabiting an Atlantic Forest Fragment. [PDF]

Am J Primatol
Wild blond capuchin anoints with millipede species that secrete a chemical capable of repelling ectoparasites, suggesting a self‐medicative function. Social and solitary anointing bouts occurred at similar frequencies, but with greater engagement by adult males, indicating that anointing is a multifunctional behavior.

Electrocutions in Free-Ranging Platyrrhine Nonhuman Primates: Diagnostic Features for a Threatening Condition. [PDF]

Am J Primatol
Epidemiological and pathological features of electrocutions in free‐ranging new‐world monkeys. ABSTRACT Electrical accidents pose a considerable threat to wildlife in anthropized regions, particularly arboreal mammals, as evidenced by cases of electrocutions in nonhuman primates (NHPs). This study characterized the frequency, anatomic distribution, and

Food or threat? Wild capuchin monkeys (Sapajus libidinosus) as both predators and prey of snakes

Primates, 2017
Snakes present a hazard to primates, both as active predators and by defensive envenomation. This risk might have been a selective pressure on the evolution of primate visual and cognitive systems, leading to several behavioral traits present in human and non-human primates, such as the ability to quickly learn to fear snakes.

Withdraw-to-eat movements of the Platyrrhine Sapajus libidinosus to the changing affordance of tubers with eating [PDF]

Animal Behavior and Cognition
The evolution of hand ability in primates is staged, with the visual control of hand shaping likely originating in Platyrrhine primates, members of a monophyletic primate suborder whose stem group diverged from catarrhines about 40 million years ago ...
