This is a natural extension of phylogeography, which allows us to understand not only the patterns of genetic variation across seascapes, but also the drivers. Here we use next generation sequencing approaches to identify both neutral SNPs and those putatively under selection that can help us disentangle the relative contributions of neutral genetic versus local adaptation processes. By looking for correlates between structure, outlier SNPs and a variety of environmental variables, we can tease apart which factors influence signals of local adaptation in marine populations. This makes it possible to assess potential impacts of climate change on the evolutionary resilience of marine species.
