Abstract

Green et al. provide the first evidence that chimpanzees are able to walk least-cost routes in a variable energy landscape. Least-cost modeling predicted the costs and sinuosity of chimpanzee paths better than local knowledge and straight-line null models. Results suggest chimpanzees use spatial knowledge of their landscape to optimize travel.
