    Dominy, Nathaniel J.; Yeakel, Justin D.; Bhat, Uttam; Ramsden, Lawrence; Wrangham, Richard W.; Lucas, Peter W. (2016)
    Figs are keystone resources that sustain chimpanzees when preferred fruits are scarce. Many figs retain a green(ish) colour throughout development, a pattern that causes chimpanzees to evaluate edibility on the basis of ...
