Resident/Intruder dynamics in surface fish versus Pachón cavefish fights. (A-B) Resident/intruder activity plots for surface fish-residents with Pachón-intruders (A) and Pachón-residents with surface fish-intruders (B) during staged fights. (C-I) Quantifications of behaviors annotated during staged fights with resident (R) and intruder (I) intra-population comparisons. 2-Way ANOVAs were performed for all behaviors, followed by Tukey’s multiple comparison’s test for resident versus intruder comparisons: When surface fish were residents: biting (p = 0.9513), striking (p = 0.7403), circling (p = 0.9935), following (p = 0.1689), escaping (p = 0.9865), freezing (p > 0.9999) and avoidance (p = 0.9712). When Pachón cavefish were residents: biting (p < 0.05), striking (p = 0.01), circling (p = 0.8589), following (p = 0.0086), escaping (p < 0.05), freezing (p = 0.2423) and avoidance (p = 0.5680). Significance: p < 0.05 (*), p < 0.01 (**), p < 0.001 (***), p < 0.0001 (****), not significant (ns)
