(From Supplementary Fig. 1). The effect of additional weight on jumping performance of Gerris latiabdominis females (a–c) and males (d–f) in First Jumps. Average Angular leg speed (a, d), Take-off angle (b, e), and Take-off velocity (c, f) of weight-not-added (white bars) and weight-added females (gray bars) are compared. Results from the Wilcoxon rank sum test (Mann–Whitney test; see Supplementary Materials Part 1 for details) are graphically presented in the figure: *P < 0.05, **P < 0.001. One marginally non-significant difference at P = 0.104 is marked in (a) to accommodate the reasoning in the text. Parametric ANOVA for this data is presented in Table 1. Additional statistical analyses are provided in Supplementary Materials Part 1. Sample sizes in a, b, c are 20 and 11 for weight-not-added and weight-added females respectively. Sample sizes in d, e, f are 15 and 16 for weight-not-added and weight-added males respectively. Error bars indicate standard errors.
