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 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: It is argued that social tolerance at Fongoli, along with the tool-assisted hunting method, permits individuals other than adult males to capture and retain control of prey, which is uncommon for chimpanzees, and asserted that tool- assisted hunting could have similarly been important for early hominins.

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.

TL;DR: Using savanna chimpanzees as a referential model, this research lends support to the notion that thermoregulatory challenges were a significant factor in hominin evolution, and suggests these challenges may have overshadowed the challenges of maintaining adequate energetic balance during the expansion of thehominin range from wetter to drier environments.
