Age‐Trajectory of Mother–Infant Relationships in Wild Assamese Macaques
American Journal of Primatology, Volume 88, Issue 1, January 2026.Maternal care in wild Assamese macaques declined sharply between 1 and 3 months of infant age as infant independence increased, and stabilized from around 6 months, with no sex differences in the trajectory. This early shift aligns with the species' seasonal breeding strategy, with females balancing investment in current and future offspring.

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.

The effect of roads on spider monkeys' home range and mobility in a heterogeneous regenerating forest [PDF]
, 2017 Arboreal fauna living in tropical ecosystems may be particularly affected by roads given their dependency on forest cover and the high vulnerability of such ecosystems to changes. Over a period of 4 yr, we followed subgroups of spider monkeys living in a

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.

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.
