(a–d) The following properties of social hierarchies were computed for each group of mice: steepness, despotism, directional consistency, and Landau’s modified h’. Male groups had overall higher scores for steepness (F(1, 20) = 12.6, p = 0.00201), despotism (F(1, 20) = 10.84, p = 0.00364, note: variances were heterogenous between conditions), and directional consistency (F(1, 20) = 21.16, p = 1.73×10−4). Means of Landau’s modified h’ over the baseline days also differed between the sexes (KW test: χ2(1) = 8.2458, p = 0.0041). None of the measures showed evidence of a sex x acute stress interaction. All tests are based on n = 22 groups (10 males, 12 females).
