Validation of an Enzyme Immunoassay for Measuring Fecal Cortisol Metabolites of Bearded (Sapajus libidinosus) and Black (Sapajus nigritus) Capuchins

International Journal of Primatology, 2017
Fecal steroid analysis is a powerful noninvasive tool for behavioral endocrinology, but enzyme immunoassays (EIAs) require experimental validation before they are applied. We conducted a physiological validation of an in-house EIA measuring fecal cortisol metabolites (FCMs) by performing an adrenocorticotrophic hormone (ACTH) challenge, dexamethasone ...

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.

Fatal Africanized bee attack in captive non-human primates (Saimiri ustus and Sapajus libidinosus)

Toxicon
Bee stings (BS) are a life-threatening issue and a growing concern for public health and animals in the Americas. We describe the clinical, pathological, and ultrastructural findings of a massive lethal bee attack in two non-human primates (NHPs). Both animals showed BS scattered throughout the skin, surrounded by a local reaction, diffuse pulmonary ...

Age affects action planning in wild bearded capuchin monkeys (Sapajus libidinosus)

2019
The study of how animals anticipate future actions is crucial to understand cognitive processes that guide behavior. Action planning involves the abilities to plan how to perform an action and to coordinate effective movements within this plan. Planning is fundamental to the execution of most daily activities, including object manipulation.

Diet and seed dispersal of bearded capuchin monkeys (Sapajus libidinosus) in Brasilia National Park

American Journal of Primatology
AbstractThe dietary ecology of a species can provide information on habitat requirements, food resources, and trophic interactions, important to guide conservation efforts of wildlife populations in endangered habitats. In this study, we investigated the dietary ecology of bearded capuchin monkeys (Sapajus libidinosus) in Brasilia National Park, in the

Synchronous Pleural and Peritoneal Mesothelioma in a Free‐Ranging Capuchin Monkey (Sapajus libidinosus)

Journal of Medical Primatology
ABSTRACTA free‐ranging capuchin monkey developed a synchronous biphasic pleural and peritoneal mesothelioma, a rare form of this tumor. Exophytic nodules were dispersed over the serosal surfaces, showing marked microscopical malignant features composed of both epithelioid and spindeloid neoplastic cells immunopositive for Pan‐Cytokeratin, Cytokeratin 5/
