Insights into Intraspecies Variation in Primate Prosocial Behavior: Capuchins (Cebus apella) Fail to Show Prosociality on a Touchscreen Task [PDF]

Behavioral Sciences (Basel, Switzerland), 2014
Over the past decade, many researchers have used food donation tasks to test whether nonhuman primates show human-like patterns of prosocial behavior in experimental settings.

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

Behavioral Contagion in Wild Ecuadorian White-Fronted Capuchins (Cebus aequatorialis). [PDF]

Am J Primatol
White‐fronted capuchins exhibit scratching contagion, but neither the characteristics of the trigger, or of the partner's (sex, age class, or centrality), or of the dyad (combination of sex, combination of age class, or social bond) seem to modulate the likelihood of contagion.

Intestinal parasites infecting captive non-human primates in Italy [PDF]

Frontiers in Veterinary Science, 2023
Non-human primates (NHPs) living in captive conditions are susceptible to intestinal parasites that can contribute to mortality and morbidity, and cause zoonotic infections.

A nonhuman primate model for genital herpes simplex virus 2 infection that results in vaginal vesicular lesions, virus shedding, and seroconversion. [PDF]

PLoS Pathogens
The most commonly used animal models for evaluating the efficacy of HSV-2 candidate vaccines are mice and guinea pigs. While numerous HSV-2 vaccine candidates have been tested in these animals and were effective in reducing disease and mortality, these ...

Bimanual Coordination and Right-Hand Bias in Extractive Foraging by Wild Sapajus libidinosus. [PDF]

Am J Primatol
Wild Sapajus libidinosus exhibit a significant preference at the population level for using their right‐hand fingers to extract nut kernels when employing bimanual coordination. ABSTRACT Bimanual coordination is considered a crucial factor in the evolution of manual lateralization.

Health Correlates of Extended Longevity in Captive Ring-Tailed Lemurs (Lemur catta). [PDF]

Am J Primatol
Male and female ring‐tailed lemurs exhibit distinct patterns of age‐related change in certain serum chemistry markers. Photo by David Haring. ABSTRACT Captive primates maintained at accredited institutions can live extraordinarily long lives and, as a result, are useful models for understanding the physiology of aging. Many institutions monitor primate

Neopterin as a Tool for Primate Ecoimmunology: Current Knowledge, Practical Application, and New Directions From Captivity to the Wild. [PDF]

Am J Primatol
Neopterin is a sensitive and specific biomarker of intracellular pathogen infection and chronic inflammation, and affected by environmental, life‐history, and sex‐contextual factors. This review offers best‐practice guidelines and practical advice on sample collection, storage, and analysis in primates when used for ecoimmunological conservation and ...

Inhibition of protein synthesis in M1 of monkeys disrupts performance of sequential movements guided by memory

eLife, 2020
The production of action sequences is a fundamental aspect of motor skills. To examine whether primary motor cortex (M1) is involved in maintenance of sequential movements, we trained two monkeys (Cebus apella) to perform two sequential reaching tasks ...

Primate populations in continuous forest and forest fragments in Central Amazonia [PDF]

Acta Amazonica, 1988
Population densities of six primate species (Saguinus midas, Pithecia pithecia, Cebus apella, Chiropotes satanas, Alouatta seniculus and Ateles paniscus) were estimated in continuous forest and in isolated reserves (one of 100 ha and four of 10 ha ...
