Understanding the invasive potential of species outside their native range is one of the most pressing questions in applied evolutionary and ecological research. Admixture of genotypes of invasive species from multiple sources has been implicated in successful invasions, by generating novel genetic combinations that facilitate rapid adaptation to new environments. Alternatively, adaptive evolution on standing genetic variation, exposed by phenotypic plasticity and selected by genetic accommodation, can facilitate invasion success. We investigated the population genetic structure of an Asian freshwater mussel with a parasitic dispersal stage, Sinanodonta woodiana, that has been present in Europe since 1979but which has expanded rapidly in the last decade. Data from a mitochondrial marker and nuclear microsatellites have suggestedthat all European populations of S. woodianaoriginate from the River Yangtze basin in China. Only a single haplotype was detected in Europe, in contrast to substantial mitochondrial diversity in native Asian populations. Analysis of microsatellite markers indicated intensive gene flow and confirmed a lower genetic diversity of European populations compared to those from the Yangtze basin, though that difference was not large. Using an Approximate Bayesian Modelling approach, we identified two areasas the probable source of the spread of S. woodianain Europe, which matched historical records for its establishment. Theirpopulations originatedfrom a single colonization event.Our data do not support alternative explanations for the rapid recent spread of S. woodiana, recent arrival of a novel (cold-tolerant)genotype or continuous propagule pressure. Instead, in situadaptation, facilitated by repeated admixture, appears to drive the ongoing expansionof S. woodiana.We discuss management consequences of ourresults.
