This study shows Guinea baboons adjust their space-use and foraging behavior in response to changes in food availability caused by a wildfire.

This study examines the relationship between maternal style and infant growth and survival in wild Guinea baboons, finding no significant link between maternal behavior and infant outcomes.

The paper examines copulation calls in Guinea baboons, finding they signal fertility but do not reflect mate competition.

The study investigates whether meat acquisition skill in male Guinea baboons signals quality and affects reproductive success, finding no evidence of such a link.

The paper reports post-mortem infant-directed behaviors in wild Guinea baboons, finding that caretaking and cannibalism occur without evidence of a death concept.

The paper analyzes camera-trap data to assess diversity and spatiotemporal activity patterns of medium and large mammals in Niokolo-Koba National Park, finding higher evenness in savannahs and higher sighting rates in forests.

The paper quantifies variation in primate social structures across 11 species, identifying distinct patterns in kin and rank biases and male-centered subgrouping.

PriMAT tracks and identifies primates in the wild using bounding boxes, achieving 84% accuracy in lemur identification with minimal labeled data.

This study examines whether Tonkean macaques and brown capuchins can evaluate others' skilfulness by observing human actors opening food containers, finding they use social information about skill in their decisions.

The paper investigates male reproductive strategies in Guinea baboons, finding that reproductive success is more influenced by age and female associations than dominance.

This study examines age-related changes in risk-taking behavior in Barbary macaques using an experimental paradigm with varying risk and reward combinations.

The study tests Tonkean macaques' preference between helper and hinderer agents in the hill paradigm and finds no preference, suggesting low attention to stimuli.

This study examines sleeping site use in Guinea baboons, finding that they use sites opportunistically rather than avoiding predators or parasites.

The paper manipulates foraging skill in male Guinea baboons and shows females adjust their social behavior based on the male's utility, not competence.

This study examines landscape partitioning in Guinea baboon parties and finds high home range overlap and low resource competition between neighboring groups.

The paper describes a novel hand-clapping gesture in a Barbary macaque, suggesting it is an agonistic signal used in combination with other communicative behaviors.

This study examines anti-snake behavior and snake classification in vervet monkeys through observational and experimental methods, finding that inspection duration varies with snake species but not size, and alarm calling is proximity-dependent.

This study shows Tonkean macaques do not prefer skilled partners in cooperative tasks, contradicting previous findings and suggesting limited social evaluation abilities.

This paper demonstrates that failing to correct for offspring age in parental care analyses leads to overestimation of parental variation, and proposes a modeling approach to address this issue.

This study compares coordination strategies in human and macaque pairs during a transparent decision game, finding that humans use dynamic turn-taking while macaques use static coordination, with one trained macaque pair showing dynamic behavior.
