Maternal ranging strategies facilitate offspring social play at energetic cost in the most solitary ape

The paper shows orangutan mothers adjust their ranging behavior to increase offspring social play, at an energetic cost.

Genetic and behavioural repertoires support olfactory communication in wild capuchin monkeys

This study examines VR gene repertoires and olfactory behaviors in wild capuchin monkeys, finding evolutionary constraint on VRs and a diverse set of olfactory behaviors suggesting a role in social communication.

Development and social dynamics of stone tool use in wild white-faced capuchin monkeys

This study examines how white-faced capuchin monkeys develop stone tool use skills in a population with limited social learning opportunities, finding that juveniles are less proficient than adults but show stable skill development over time.

Environmental fluctuations alter the competitive trade-offs of group size in a social primate

The paper shows how environmental changes affect competition between and within groups of capuchin monkeys, altering their space use and foraging strategies.

White-faced capuchins (Cebus capucinus imitator) exhibit selectivity for stone tools

The paper studies stone tool selectivity in white-faced capuchin monkeys to infer archaeological signatures of tool use in primates and humans.

Life on the edge: diet preferences reflect adaptation to drought in Neotoma fuscipes

This study examines how diet preferences of dusky-footed woodrats reflect adaptation to drought in a heterogeneous environment, finding age and proximity to edge habitat influence food selection.
