Intuitive probabilistic inference in capuchin monkeys
Animal Cognition, 2016 The ability to reason about probabilities has ecological relevance for many species. Recent research has shown that both preverbal infants and non-human great apes can make predictions about single-item samples randomly drawn from populations by reasoning about proportions.

Same/different concept learning by capuchin monkeys in matching-to-sample tasks.
PLoS ONE, 2011 The ability to understand similarities and analogies is a fundamental aspect of human advanced cognition. Although subject of considerable research in comparative cognition, the extent to which nonhuman species are capable of analogical reasoning is ...

Renal artery in tufted capuchin monkey: structure and morphometry
Acta Scientiarum: Biological Sciences, 2018 The objective was to describe the structure of the renal artery in capuchin monkey at the level of the proximal and distal arterial segments. Morphometric analysis was performed referring to the thickness and quantification of tissue elements of the ...

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.

Capuchin Monkeys Alternate Play and Reward in a Dual Computerized Task [PDF]
Animal Behavior and Cognition, 2015 Many animals cooperate with one another to achieve outcomes that they could not obtain on their own. One form of cooperation that has received much attention but little empirical support from experimental studies is reciprocity, leaving open the question

Evidence for abstract representations in children but not capuchin monkeys
Cognitive Psychology, 2023 The use of abstract higher-level knowledge (also called overhypotheses) allows humans to learn quickly from sparse data and make predictions in new situations. Previous research has suggested that humans may be the only species capable of abstract knowledge formation, but this remains controversial.

Integrative Zoology, EarlyView.We provide an early description of the gut microbiome of wild, free‐ranging Asian elephants (Elephas maximus). Using 16S rRNA gene amplicon data from 123 fecal samples collected across 6 months in two Sri Lankan national parks, we found that gut microbiome composition varied significantly by sampling month and, to a lesser extent, by park.

Can Food Acquisition Priority Alter Emotion, Physiological Responses, and Social Rank in Fish?
Integrative Zoology, EarlyView.We tested whether a cichlid fish perceives inequitable food distribution by manipulating feeding order. Priority‐fed individuals consumed more, had higher condition factors, and exhibited lower whole‐body cortisol than delayed‐fed fish, while personality, metabolism, dopamine, and social rank did not differ.
