    GLMM results for the effect of chimpanzee activity on ARU drum detections of chimpanzees at Taï, with daily rainfall (mm) added as a control fixed effect. We checked for collinearity using variance inflation factors derived using the function ‘vif’ of the package ‘car’ [1] applied to a standard linear model lacking the random effects. The effect of chimpanzee ranging activity remained significant at a one kilometer detection radius, and rain had no effect on ARU detection probability (N = 1391). Similarly, results remained a trend (P = 0.065) with a 500 m detection radius (see Additional file 3 and main manuscript). (DOCX 15 kb
