Probability that black howler monkeys selected a quadrat to navigate at least in four different occasions in relation to the relative elevation within their home range and FTs density (proxy for visual access to FTs). The height of spheres represents the probability that a certain quadrat was chosen to navigate per combination of elevation and FTs density. Each surface (i.e., square) represents the expected probability of a quadrat to be chosen according to the model (conditional on all other predictors being set at their average value). Sphere size corresponds to the relative number of observations, with closed circles being above the model surface and open circles below
