<i>Sex peptide receptor</i>-regulated polyandry modulates the balance of pre- and post-copulatory sexual selection in <i>Drosophila</i>, Published online: 17 January 2019; doi:10.1038/s41467-018-08113-w

Theory predicts that mating systems influence the relative strength of sexual selection before and after mating. Here, Morimoto and colleagues demonstrate that higher polyandry weakens precopulatory while strengthening post-copulatory sexual selection on males in Drosophila melanogaster.
