Female mate preferences for ecologically relevant traits can forge a link between mate choice within species and sexual isolation between species. We investigate female mate preferences for two ecologically important traits, body shape and size, in a species pair of threespine stickleback. Our results show that female preferences for size and shape may contribute to sexual isolation between benthic and limnetic sticklebacks and enhance population divergence of these ecologically important traits.
