Phylogeography of Petrolisthes armatus, an invasive species with low dispersal ability

Abstract Theoretically, species with high population structure are likely to expand their range, because marginal populations are free to adapt to local conditions; however, meta-analyses have found a negative relation between structure and invasiveness. The crab Petrolisthes armatus has a wide nati...
