要旨
Adam van Casteren et al. report that chimpanzee foods in savannah woodlands are more mechanically demanding than those in tropical forests. This study, based on carbon and nitrogen isotope signature analysis and measurements of the mechanical properties of common food sources, suggests that chimpanzees may adapt their dietary niche to environmental conditions.
