Anatomical analysis of thumb opponency movement in the capuchin monkey (Sapajus sp). [PDF]

PLoS ONE, 2014
Capuchin monkeys present a wide variety of manipulatory skills and make routine use of tools both in captivity and in the wild. Efficient handling of objects in this genus has led several investigators to assume near-human thumb movements despite the ...

Demographic buffering in natural populations: A multi‐level perspective

Journal of Animal Ecology, EarlyView.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

A MAXIMUM ENTROPY MODEL OF THE BEARDED CAPUCHIN MONKEY HABITAT INCORPORATING TOPOGRAPHY AND SPECTRAL UNMIXING ANALYSIS [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Movement patterns of bearded capuchin monkeys (Cebus (Sapajus) libidinosus) in northeastern Brazil are likely impacted by environmental features such as elevation, vegetation density, or vegetation type.

Gut Microbiota of Gray Snub‐Nosed Monkeys: Adaptation to Seasonal Variations Through Energy Compensation and Thermogenesis

Integrative Zoology, EarlyView.
Based on metagenome‐assembled genomes (MAGs), the gut microbiota of the gray snub‐nosed monkeys recovered 1229 non‐redundant MAGs. The gut microbiota showed an enhanced capacity to produce energy substrates with increased conversion activity of these substrates during winter.

Brown lemurs (Eulemur fulvus) can master the qualitative version of the reverse-reward contingency. [PDF]

PLoS ONE, 2012
Behavioral flexibility that requires behavioral inhibition has important fitness consequences. One task commonly used to assess behavioral inhibition is the reverse-reward task in which the subject is rewarded by the non selected items.

Activity budget and social behavior of urban capuchin monkeys, Sapajus sp. (Primates: Cebidae)

Zoologia (Curitiba), 2019
Constant changes in natural environments impose challenges to wild animal populations, especially those that depend on social life. We gathered data on the activity budget and social interactions of a capuchin monkey (Sapajussp.) group of 17 individuals ...

An Introduction to Rational Constructivism in Cognitive Development

Topics in Cognitive Science, EarlyView.
Abstract Rational constructivism is a contemporary theory of cognitive development. It proposes that children generate, tweak, and radically revise theories, beliefs, and representations by integrating evidence with existing knowledge via probabilistic inferential learning mechanisms.

Hematology and Serum Biochemistry Reference Intervals for Captive‐Born Owl Monkeys (Aotus nancymae): Effects of Age and Sex

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT Background Owl monkeys (Aotus spp.) are a nocturnal nonhuman primate (NHP) native to central and South America that are used as infectious disease research models for human diseases, such as malaria and human immunodeficiency virus. Natural and infectious diseases may cause alterations in the hematology and serum biochemistry values, which ...
