自然界中性冲突的普遍存在，以及由此产生的共同进化轨迹的潜在随机性，使其成为表型分歧和物种形成的重要驱动因素，即使在没有环境差异的情况下也能发挥作用。因此，大多数研究性冲突在种群分化/物种形成中的作用的实证工作都是在统一的环境中完成的，生态学的任何作用在很大程度上都被忽略了。然而，理论表明自然选择可以限制受性冲突影响的表型。我们使用适应替代环境的果蝇复制种群来测试生态如何影响雄性对雌性长寿的影响的进化。男性缩短女性寿命的程度，以及女性对这种伤害的抵抗力，都与对不同环境的适应有关。我们的结果表明，生态学在塑造性冲突下人口特征差异模式方面发挥着核心作用。
The prevalence of sexual conflict in nature, along with the potentially stochastic nature of the resulting coevolutionary trajectories, makes it an important driver of phenotypic divergence and speciation that can operate even in the absence of environmental differences. The majority of empirical work investigating sexual conflict's role in population divergence/speciation has therefore been done in uniform environments and any role of ecology has largely been ignored. However, theory suggests that natural selection can constrain phenotypes influenced by sexual conflict. We use replicate populations of Drosophila melanogaster adapted to alternative environments to test how ecology influences the evolution of male effects on female longevity. The extent to which males reduce female longevity, as well as female resistance to such harm, both evolved in association with adaptation to the different environments. Our results demonstrate that ecology plays a central role in shaping patterns of population divergence in traits under sexual conflict.
