This project aims to outline a broadly applicable approach for estimating sex-specific selection, which is based on an extension of the theory of local adaptation with gene flow. Adaptive evolution can be constrained when patterns of selection differ between the sexes. Experiments using model organisms provide strong evidence for adaptive constraints due to sex differences in selection. Outside of these model systems, sex-specific selection estimates are difficult to obtain because methods for estimating selection are not easily applied to natural populations. Experiments, using a clinally variable Drosophila population from Eastern Australia constitute the first tests of the new theory.

本计画的目的是提出一个广泛适用的方法来估计性别特异性选择，此方法是以基因流局部适应理论的延伸为基础。当两性之间的选择模式不同时，适应性进化就会受到限制。使用模式生物的实验提供了强有力的证据，适应性的限制，由于性别差异的选择。在这些模型系统之外，很难获得性别选择估计，因为估计选择的方法不容易应用于自然群体。实验中，使用了来自澳大利亚东部的果蝇种群，构成了对新理论的第一次测试。
