The aim of this study is to further elucidate ecological factors of termite taxa which could be shaping chimpanzee tool using behaviour across equatorial Africa. Towards this goal, reports of Macrotermes and Pseudocanthotermes assemblages at chimpanzee study sites were compiled. More specific comparisons were made between termite prey and chimpanzee behaviour at two central African sites to address the following questions: What Macrotermitinae prey are available in the Dja and Ndoki forests? Are these termites consumed by chimpanzees and are the same techniques used to prey upon termites at both sites? Are there ecological features that could be shaping differences in tool using behaviour within or between sites? Insights into the relationship between chimpanzees and termites in the Congo Basin can then be extended to a larger context of termite distribution and patterns of chimpanzee tool using in termite predation across equatorial Africa. Chimpanzee tool using behaviours are likely to be based on a combination of ecological and social factors, so clarifying the ecological forces shaping termite predation enhances our understanding of chimpanzee tool traditions.
