This study examines the social and fitness outcomes of a group fusion in hybrid baboons, finding no detectable fitness costs and rapid social integration.

The paper provides four newly available data sets from a long-term study of wild baboons in Amboseli, Kenya, covering demographics, activity, diet, and weather data spanning 1971-2023.

This study models the coevolution of sexual signaling and discrimination under varying mating conditions, finding two equilibria: one with indiscriminate mating and no signals, and another with perfect signaling and exclusive different-sex behavior.

This study re-examines the link between maternal sociality and infant survival in wild baboons, finding that the relationship is confounded by reproductive state and infant presence.
