Close encounters of the friendly kind: pacific between‐group interactions in primates
Biological Reviews, Volume 100, Issue 6, Page 2257-2284, December 2025.ABSTRACT While intergroup conflict features prominently in the behavioural ecology literature, its antonym, intergroup peace, has been a rather neglected phenomenon until recently. Neighbourly relations and affiliative interactions are far from uncommon.

Ontogenetic Changes in Feeding Behaviors in Tufted Capuchins
American Journal of Biological Anthropology, Volume 187, Issue 4, August 2025.ABSTRACT Objectives Wild juvenile capuchins exhibit lower feeding success than adults, particularly for mechanically challenging foods, but ontogenetic changes in oral food processing behaviors related to this reduced success are unknown. We test how oral food processing efficiency varies across development in an experimental setting in tufted ...

Habitat Use and the Demographics of Object Manipulation by Wild Chacma Baboons
American Journal of Biological Anthropology, Volume 187, Issue 3, July 2025.Object manipulation by chacma baboons (Papio ursinus) in Gorongosa National Park varies by age, sex, and habitat type, with playful use more common in juveniles and food‐focused use in adults, especially in anthropogenic environments. ABSTRACT Objectives Studying object manipulation may offer insights about the emergence of habitual tool use in the ...

Mother–Infant Face‐to‐Face Interactions Serve a Similar Function in Humans and Other Apes
Developmental Science, Volume 28, Issue 3, May 2025.ABSTRACT In humans, mothers and infants often engage in face‐to‐face interactions, which are often considered crucial for the social transmission of information and the typical social and cognitive development of infants. In this study, we used a comparative developmental perspective to provide an assessment of mother–infant face‐to‐face interactions ...

International Journal of Primatology, 2022 Abstract Vertebrate predation was a vital behavior during human evolution. Some non-human primates, such as baboons and chimpanzees, frequently hunt and consume vertebrate prey. Capuchin monkeys (Cebus and Sapajus) are omnivorous neotropical primates, and although vertebrate prey is not their primary food source, they hunt and consume those ...
