Predicted male incursion rate as a function of the interaction between population size and whether the group contained a single versus multiple adult males. Expected proportions were obtained by plotting the predictions of the GLMMs (Table 2), setting all additional predictors to their mean values (or median values for categorical variables). Measures of population size have been z-score transformed.
