Age‐Related Changes in Marmoset (Callithrix jacchus) Feeding Behavior and Physiology: Insights of Masticatory and Swallowing Functions

American Journal of Primatology, Volume 87, Issue 8, August 2025.
This study investigated the feeding and swallowing physiology of 26 marmosets (1 month to 19 years old). Using a non‐invasive cineradiography setup, the study examined key age‐related differences in oral and pharyngeal swallowing phases across four age groups: infant, adult, old, and very old.

Strategies, costs and counter‐strategies to sexual coercion

Biological Reviews, Volume 100, Issue 4, Page 1557-1577, August 2025.
ABSTRACT Sexual conflict, the conflict between the evolutionary interests of females and males over mating, occasionally results in the evolution of traits favourable for one sex and adverse for the other. In this context, males can use sexual coercion to increase their mating success, at the expense of their female targets' mate choice.

Vocal Repertoire of Cebus capucinus: Acoustic Structure, Context, and Usage

International Journal of Primatology, 2008
Researchers studying nonhuman primate vocal repertoires suggest that convergent environmental, social, and motivational factors account for intra- and interspecific vocal variation. We provide a detailed overview of the vocal repertoire of white-faced capuchins, including acoustic analyses and contextual information of vocal production and vocal usage ...

To Hunt or Patrol? Social Composition and Location Mediate Scent Marking Decisions of a Large Carnivore

Ecology and Evolution, Volume 15, Issue 6, June 2025.
Using a unique set of near‐continuous behavioral observations of free‐ranging wild dog packs, we combine field data with GPS locations to make inferences on how sociality mediates territorial strategies in a large carnivore. By investigating habitat selection across territorial behaviors, we make multi‐scale inferences on how inter‐ and intra‐pack ...
