Dietary Response of Chimpanzees and Cercopithecines to Seasonal Variation in Fruit Abundance I. Antifeedants International Journal of Primatology Continued isotopic research has indicated that across chimpanzee habitats, from rainforest to savannah, the values of δ13C and δ15N vary significantly21,22.
