 Abstract: Although chimpanzees (Pan troglodytes) are ripe fruit specialists, they sometimes consume other plant parts including subterranean organs like roots and tubers. Such plant parts, which include underground storage organs (USOs), have been found to play a key role in the diets of some chimpanzee populations as well as, potentially, our hominin ancestors. We report the confirmed consumption of subterranean plant organs of three species — sweet potatoes (Ipomoea batatas), yams (Dioscorea alata) and peanuts (Arachis hypogaea), as well as unconfirmed consumption of cassava (Manihot esculenta) — by chimpanzees in a human-dominated landscape in western Uganda. These observations point toward the dietary flexibility of chimpanzees inhabiting anthropogenic landscapes, though mechanisms of novel food acquisition, particularly for subterranean fruits and tubers, are not well understood. Dietary flexibility may help chimpanzees survive as natural forest resources disappear, but simultaneously may bring them into greater conflict with their human neighbours, thereby further imperilling them.
