Sources of Variation in Fecal Haptoglobin in a Population of Wild Capuchin Monkeys (Cebus imitator). [PDF]

Am J Primatol
Fecal haptoglobin values show significant seasonal variation in wild capuchin monkeys. Values are highest, and most variable in the early‐mid dry season, when fruit is typically scarce and water sources are standing pools, which can accumulate pathogens.

Follicular Atresia, Cell Proliferation, and Anti-Mullerian Hormone in Two Neotropical Primates (Aotus nancymae and Sapajus macrocephalus)

Animals, 2023
This study evaluated the follicular atresia, cell proliferation, and anti-Mullerian hormone action in Aotus nancymae and Sapajus macrocephalus during three sexual phases (follicular, luteal, and gestational).

ON LOSS AVERSION IN CAPUCHIN MONKEYS [PDF]

Journal of the Experimental Analysis of Behavior, 2008
Chen, Lakshminarayanan, and Santos (2006) claim to show in three choice experiments that monkeys react rationally to price and wealth shocks, but, when faced with gambles, display hallmark, human‐like biases that include loss aversion. We present three experiments with monkeys and humans consistent with a reinterpretation of their data that attributes ...

Primate richness and abundance is driven by both forest structure and conservation scenario in Costa Rica.

PLoS ONE, 2023
Variation in tropical forest management directly affects biodiversity and provisioning of ecosystem services on a global scale, thus it is necessary to compare forests under different conservation approaches such as protected areas, payments for ...

Can I Have a Bite? The Influence of Infant Begging on Food Sharing in Capuchin Monkeys (Sapajus Libidinosus). [PDF]

Am J Primatol
Food sharing between mother and offspring in capuchin monkeys is a response to the infant's begging. Infants solicit more frequently high‐quality and hard‐to‐process foods and they are more likely to succeed when they are older and if the food item is not a lizard. ABSTRACT In primates, food sharing from mothers to infants may serve two main functions:

Endowment effect in capuchin monkeys [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2008
In humans, the capacity for economically rational choice is constrained by a variety of preference biases: humans evaluate gambles relative to arbitrary reference points; weigh losses heavier than equally sized gains; and demand a higher price for owned goods than for equally preferred goods that are not yet owned. To date, however,

Variation in personality can substitute for social feedback in coordinated animal movements

Communications Biology, 2021
Planas-Sitjà, Deneubourg and Cronin use a theoretical approach to examine the importance of personality and feedback in the emergence of collective movement decisions in animal groups.

Unexpected rabies variant identified in kinkajou (Potos flavus), Mato Grosso, Brazil

Emerging Microbes and Infections, 2020
A second case of a novel rabies variant described once in a capuchin monkey from Mato Grosso, Brazil, was discovered in a rabid wild kinkajou from the same region, indicating a public health risk following exposure to either of the two animals.

Identification of multiple TAR DNA binding protein retropseudogene lineages during the evolution of primates

Scientific Reports, 2022
The TAR DNA Binding Protein (TARDBP) gene has become relevant after the discovery of its several pathogenic mutations. The lack of evolutionary history is in contrast to the amount of studies found in the literature.

Capuchin monkeys are sensitive to others' welfare [PDF]

Current Biology, 2008
SummaryHumans demonstrate altruistic behaviors in a variety of contexts [1,2], but there is growing experimental evidence that our closest living primate relative, the chimpanzee, does not always share our human prosocial tendencies [3,4]. Although chimpanzees behave cooperatively in some contexts, there is growing evidence that chimpanzees are ...
