Object-Based Warping During Distance Discriminations by Rhesus Monkeys (Macaca mulatta) and Capuchin Monkeys (Sapajus apella) [PDF]

Animal Behavior and Cognition
Humans and nonhuman animals misperceive the world. However, they do not always share the same misperceptions. Vickery and Chun (2010) reported a visual illusion, object-based warping, wherein distances between stimuli contained within an object were ...

The presence of neuronal-specific nuclear protein (NeuN) in the circadian timing system of the capuchin monkey (Cebus apella)

Sleep Science, 2010
Background and objective: The circadian timing system (CTS) is composed of a group of specialized neuronal structures that establish a temporal organization of physiological and behavioral processes within precise patterns.

Taxon, Arboreality, Sex, and Season—Factors Influencing Gastrointestinal Parasite Occurrence in Zoo‐Housed Non‐Human Primates

Zoo Biology, EarlyView.
ABSTRACT The emergence of anthelminthic resistance is a well‐documented phenomenon in livestock and companion animals. Given the scarcity of new antiparasitic drugs, the implementation of effective, holistic anthelminthic control strategies is critical to preserving the efficacy of existing treatments.
