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

American Journal of Primatology, Volume 88, Issue 1, January 2026.
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.

Quality and overlap of individual core areas are related to group tenure in female spider monkeys [PDF]

In species with a high degree of fission-fusion dynamics group members may differ in the use of the group home range to reduce food competition. Such differential use may result in distinct individual core areas.

Behavioral Contagion in Wild Ecuadorian White‐Fronted Capuchins (Cebus aequatorialis)

American Journal of Primatology, Volume 88, Issue 1, January 2026.
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.

No short-term contingency between grooming and food tolerance in Barbary macaques (Macaca sylvanus) [PDF]

, 2015
The exchange services such as allo-grooming, allo-preening, food tolerance and agonistic support has been observed in a range of species. Two proximate mechanisms have been proposed to explain the exchanges of services in animals.

Hematological and biochemical profile of spider monkey (Ateles geoffroyi) in captivity

Agro Productividad, 2021
Objective: To estimate the hematological and biochemical reference values inMAteles geoffroyi individuals in captivity. Methodology: Eleven males and 23 females were captured. We collected blood,from the coccygian vein; conventional techniques were used to analyze thesamples.Results: mean corpuscular volume (MCV; P < 0.03), platelets (PLT; P ...

Copromicroscopic Diagnosis and Prevalence of Intestinal Parasites in Humans and Nonhuman Primates That Share an Ecosystem in the State of Veracruz, Mexico

Journal of Parasitology Research, Volume 2026, Issue 1, 2026.
The expansion of human populations and their associated land use practices are contributing to the fragmentation of forest ecosystems, thereby impacting the habitats of wildlife, including nonhuman primates (NHPs). This increased proximity between humans and NHP, which share an ecosystem, creates opportunities for the transmission of gastrointestinal ...

Inhibitory control tests in non‐human animals: validity, reliability, and perspectives

Biological Reviews, Volume 100, Issue 6, Page 2482-2507, December 2025.
ABSTRACT Inhibitory control, the ability to control impulsive or pre‐learned behaviour in order to reach a more rewarding goal, is essential in many aspects of normal life. In non‐human animals, better inhibitory control performances have been associated with a larger brain, better problem‐solving skills, and fitness benefits.

Prevalence of fur mites (Acari: Atopomelidae) in non-human primates of Costa Rica

Revista de Biología Tropical, 2009
Parasites have been investigated for some New World primates; however, very little is known about ectoparasites and specifically fur mites. In this study, Alouatta palliata, Cebus capucinus, Saimiri oerstedii, and Ateles geoffroyi monkeys from different ...
