Male-biased stone tool use by wild white-faced capuchins (Cebus capucinus imitator)

The paper investigates sex differences in stone tool use among wild white-faced capuchins, finding that male-biased tool use on one island is not due to physical, environmental, or social constraints.

Coupling of Coastal Activity with Tidal Cycles is Stronger in Tool-using Capuchins (Cebus capucinus imitator)

The study compares coastal activity patterns of tool-using and non-tool-using capuchin monkeys in relation to tidal cycles, finding tool users show stronger and more consistent ties to tidal patterns.

Cultural diffusion dynamics depend on behavioural production rules

This study presents a generative model integrating social transmission and production rules to show how individual-level behavioural rules influence cultural diffusion dynamics and inferential model performance.

Processing of novel food reveal payoff and rank-biased social learning in a wild primate

The paper studies social learning in vervet monkeys, showing they prefer high-payoff techniques and higher-ranking demonstrators, leading to stable behavioural traditions.

The Evolution of Bequeathal in Stable Habitats

The paper presents a mathematical model of bequeathal evolution in stable habitats, finding that natural selection favors it under specific conditions involving competition, mortality, and dispersal.

Rapid environmental change in games: complications and curiosities

The paper shows that existing game theory models require additional mechanistic details to predict the effects of rapid environmental change on behavior.

Habitual stone-tool aided extractive foraging in white-faced capuchins, Cebus capucinus

This study reports the first documented case of habitual stone-tool use in a gracile capuchin species, highlighting ecological and evolutionary factors influencing tool use.

Payoff-biased social learning underlies the diffusion of novel extractive foraging traditions in a wild primate

The paper studies social learning strategies in wild capuchin monkeys, finding payoff-biased and age-biased learning drive the spread of new foraging techniques.
