Abstract

Optimising energy balance is challenging for terrestrial animals living in rugged, montane environments, where available energy is relatively low and travel costs are high. Spatial analyses of chimpanzee travel routes collected over 14 months at the altitudinal extreme of their range revealed that they reduce travel effort during periods of fruit scarcity. Chimpanzees preferentially travelled on human-made trails, re-used their own travel routes and show evidence of using knowledge of the trails and topography of their home-range to plan energy-efficient routes. This research reveals new behavioural strategies that allow chimpanzees to reduce their energy expenditure in harsh, high-elevation environments.
