Table 2.
Results from General Linear Models (GLMs) with avoidance scores as the dependent variable. (A) Experiment 1; comparison between Poecilia spp. from sulfidic and non-sulfidic waters. (B) Experiment 2; comparison between surface and cave mollies. (C) Experiment 3; comparison between predator-experienced and naïve surface-dwelling P. mexicana. Significant effects are in boldface.
