The effects of: (A) Search cost to novel female mating preference (D₂₂), and (B) Ecological fitness cost to novel male cue trait (C₂₂) on the probability of cascade reinforcement versus species-wide reinforcement (z-axis) for Ecological Scenario 1 in Figure 1. All other parameters and starting conditions are identical to Figure 3A. See section “Model” for details on how fitness costs to females and males was modeled.
