Contexts of Anointing Behavior in a Group of Blond Capuchin Monkeys (Sapajus flavius) Inhabiting an Atlantic Forest Fragment. [PDF]

Am J Primatol
Wild blond capuchin anoints with millipede species that secrete a chemical capable of repelling ectoparasites, suggesting a self‐medicative function. Social and solitary anointing bouts occurred at similar frequencies, but with greater engagement by adult males, indicating that anointing is a multifunctional behavior.

Behavioral Contagion in Wild Ecuadorian White-Fronted Capuchins (Cebus aequatorialis). [PDF]

Am J Primatol
White‐fronted capuchins exhibit scratching contagion, but neither the characteristics of the trigger, or of the partner's (sex, age class, or centrality), or of the dyad (combination of sex, combination of age class, or social bond) seem to modulate the likelihood of contagion.

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 ...

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.

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 ...

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.

Spontaneous cerebral amyloid angiopathy‐related intracerebral hemorrhages in aged capuchin monkey [PDF]

Alzheimers Dement
Abstract Background Cerebral amyloid angiopathy (CAA) is characterized by accumulation of β‐amyloid (βA) protein in cerebral vessels. Animals models are important for studies in AD and CAA. However, among the animal models that have been described, none developed CAA‐related intracerebral hemorrhage.

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.
