Genetic structure in native and non-native populations of the direct-developing gastropod Crepidula convexa
International audience In many marine invertebrate species, larval development plays an important role in population connectivity and gene flow: species with direct benthic development generally show more genetic structure than those with planktonic development. We used nuclear markers (microsatelli...
