Estimates are given relative to the intercept. Significant differences between species (Micrixalus saxicola (M.s.), Staurois parvus (S.p)) and/or stimuli (acoustic (A), visual (V) and multimodal (M)) in the frequency of single behavioral responses (call, tap, foot flag) or their sum are marked with asterisks.
