Distribution of sex-biased movements versus intergroup conflicts for the subset of social mammals for which data on the sexual distributions in collective action is available for both contexts. The size of each circle (and numbers inside each) reflect the numbers of species represented in each of the nine possible categories. Female-biased movements and male-biased intergroup conflict was the most common pattern (n= 10 species). Intergroup conflict was male-biased for all species with male-biased (n = 6) or unbiased (n = 4) leadership in movements. Female-bias in intergroup conflict (n = 4) or unbiased (n = 7) only emerged in species with a female bias in movements. (Online version in colour.)
