My research program uses experiments, genomics, and modelling to test the hypothesis that genetic divergence within populations of direct-developing intertidal snails is maintained by spatial variation in selection by predators and by the risk of dislodgement from waves. My long-term field predator invasion experiments on Vancouver Island, Canada test the prediction that transplanting predatory shore crabs into wave-exposed areas where they are normally rare will cause evolution of a microgeographic cline in shell thickness in the surrounding populations of

我的研究计划使用实验，基因组学和建模来检验以下假设：直接发育间隔蜗牛种群中的遗传差异通过捕食者的选择空间变化以及从波中脱离波的风险来维持。我在加拿大温哥华岛上进行的长期野外捕食者入侵实验测试了将掠食性海岸蟹移植到海浪暴露区域的预测，在这些区域中，它们通常很少见，在周围的壳厚度中，它们会导致微地理层的演变
