Abstract
Coexistence between humans and wildlife is possible when animals are
able to meet their ecological requirements while managing human-induced
risks. Other than large carnivores, examination of fine-scale
spatiotemporal interactions with humans have rarely been applied to
threatened wildlife such as great apes, whose conservation relies on
persistence in dynamic, shared landscapes. Using a landscape of fear
framework with Bayesian INLA spatiotemporal modelling we investigate
risk-mitigation and optimal foraging trade-offs in western chimpanzees
(Pan troglodytes verus). Although humans and chimpanzees used the same
locations within the agroforest landscape, chimpanzee space use was
negatively mediated by villages and agriculture. However, chimpanzees
responded to wild fruit scarcity by intensifying their use of village
areas with cultivated fruits. Our data demonstrate dynamic
spatiotemporal interactions in shared landscapes. An INLA-based
landscape of fear approach generates a clear model output to examine
risk mitigation/optimal foraging strategies, that can inform
conservation interventions to promote human-wildlife coexistence.
