TL;DR: It is shown that chimpanzees exhibit greater behavioural diversity in environments with more variability — in both recent and historical timescales, suggesting that environmental variability was a critical evolutionary force promoting the behavioural, as well as cultural diversification of great apes.

TL;DR: The ritualized behavioural display and collection of artefacts at particular locations observed in chimpanzee accumulative stone throwing may have implications for the inferences that can be drawn from archaeological stone assemblages and the origins of ritual sites.

TL;DR: The results support the view that “culturally significant units” should be integrated into wildlife conservation and show that chimpanzees inhabiting areas with high human impact have a mean probability of occurrence reduced by 88%, across all behaviors, compared to low-impact areas.

TL;DR: The rate of population change for the western chimpanzee, Pan troglodytes verus, over a 24‐year period is assessed and a plea for greater commitment to conservation in West Africa across sectors is made.
