Sexual selection is predicted to drive the coevolution of mating signals
and preferences (mating traits) within populations, and could play a role
in speciation if sexual isolation arises due to mating trait divergence
between populations. However, few studies have demonstrated that
differences in mating traits between populations result from sexual
selection alone. Experimental evolution is a promising approach to
directly examine the action of sexual selection on mating trait divergence
among populations. We manipulated the opportunity for sexual selection
(low versus high) in populations of Drosophila pseudoobscura. Previous
studies on these experimental populations have shown that sexual selection
manipulation resulted in the divergence between sexual selection
treatments of several courtship song parameters, including IPI
(inter-pulse interval) which markedly influences male mating success.
Here, we measure female preference for IPI using a playback design to test
for preference divergence between the sexual selection treatments after
130 generations of experimental sexual selection. The results suggest that
female preference has coevolved with male signal, in opposite directions
between the sexual selection treatments, providing direct evidence of the
ability of sexual selection to drive the divergent coevolution of mating
traits between populations. We discuss the implications in the context
sexual selection and speciation.
