Diversification under sexual selection: the relative roles of mate preference strength and the degree of divergence in mate preferences.

In the 6 case studies involving more than one display trait, there was never a significant relationship between trait means and our estimates for Δt ( P ≥ 0.31) or for Δp ( P ≥ 0.33); in four of the case studies the relationship between trait mean and preference strength was also non-significant ( P ≥ 0.35), but in 2 case studies it was significant or marginally significant ( Gryllus spp.; P = 0.03; Enchenopa ; P = 0.07, although the latter relationship was negative).
