Figure 1: Visualization of the GLMM results on the proportion of female Poecilia mexicana (N = 77) that reached their full reproductive potential (i.e., gave birth to three litters) within the limits of our experiment.

(A) The three significant main effects (ecotype, light regime and food regime) combined for cave and surface molly females. White represents the proportion of females that reached their full reproductive potential, black the proportion that failed to do so and numbers within the bars represent sample sizes. (B) Visualization of the significant interaction effect ‘ecotype-by-light regime’ and (C) the non-significant interaction effect ‘ecotype-by-food regime’ using estimated marginal means ± SEM.
