Environmental adaptation often involves spatially heterogeneous selection at many genetic loci. Thus, the evolutionary consequences of hybridisation between populations adapted to different environments depend on the coupled dynamics of multiple loci under selection, migration and genetic drift, making them challenging to predict. In this talk, I will in-troduce theoretical approximations that accurately capture the effect of such coupling on allele frequencies at individual loci, while also accounting for the stochastic effects of gene-tic drift. These approximations will then be used to analyse hybridisation in a subdivided population with multiple habitats under divergent selection. I will discuss when polygenic local adaptation can be maintained in a sub-divided population despite migration and how this affects neutral gene ˛ow between habitats.
