Arboreal and Terrestrial Frugivore Vertebrate Assemblage Diversity and Composition Vary With Disturbance Histories in Guianan Forests

Ecology and Evolution, Volume 16, Issue 10, October 2026.
This study examined the impact of human disturbances on arboreal and terrestrial fruit‐consuming vertebrate assemblages across three tropical forest sites in French Guiana. While species richness remained consistent across sites, results revealed significant variations in visitation rates and a shift in dominant species.

Claustrum projections to prefrontal cortex in the capuchin monkey, Cebus apella.

Frontiers in Systems Neuroscience, 2014
We examined the pattern of retrograde tracer distribution in the claustrum following intracortical injections into the frontal pole (area 10), dorsal (area 9), and ventral lateral (area 12) regions of the rostral prefrontal cortex in the tufted capuchin ...

An efficient computerized testing method for the capuchin monkey (Cebus apella): Adaptation of the LRC-CTS to a socially housed nonhuman primate species [PDF]

Behavior Research Methods, 2008
Even with advances in automated testing techniques, the capuchin monkey (Cebus apella) can be a difficult species to test in the laboratory, given its social/behavioral tendencies and typical activity pattern. Laboratories that maintain social colonies of capuchin monkeys are able to separate and test individuals, but the process can be very effortful ...

Genetic variability in two captive colonies of Cebus apella paraguayanus (primates: platyrrhini) from eastern Paraguay [PDF]

Caryologia, 2004
The tufted capuchin, Cebus apella is a New World Monkey (NWM) species widely used in biomedicine. Its genetic variability has been assessed through various genetic tools. The present study offers a cytogenetic charac- terization of two captive colonies of Paraguayan specimens, in order to increase the current information on the role of cytogenetic ...

The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

Biological Reviews, Volume 101, Issue 3, Page 1235-1254, June 2026.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated
