In accordance with the consensus that sexual selection is responsible for therapid evolution of display traits on macroevolutionary scales, microevolution-ary studies suggest sexual selection is a widespread and often strong form ofdirectional selection in nature. However, empirical evidence for the contem-porary evolution of sexually selected traits via sexual rather than naturalselection remains weak. In this study, we used a novel application of quanti-tative genetic breeding designs to test for a genetic response to sexual selec-tion on eight chemical display traits from a field population of the fly,Drosophila serrata. Using our quantitative genetic approach, we were able todetect a genetically based difference in means between groups of males des-cended from fathers who had either successfully sired offspring or were ran-domly collected from the same wild population for one of these display traits,the diene (Z,Z)-5,9-C27 : 2. Our experimental results, in combination withprevious laboratory studies on this system, suggest that both natural and sex-ual selection may be influencing the evolutionary trajectories of these traitsin nature, limiting the capacity for a contemporary evolutionary response.
