Genetic characterization of the Iberian populations of two invasive mollusks: zebra mussel and asiatic clam
The zebra mussel and the Asian clam are two invasive aquatic species worldwide. Both species are present in the Iberian Peninsula for several years. However, introduction history and colonization routes of these two invasive species in the Iberian Peninsula remain mainly unknown. We have developed n...

| Sumario: | The zebra mussel and the Asian clam are two invasive aquatic species worldwide. Both species are present in the Iberian Peninsula for several years. However, introduction history and colonization routes of these two invasive species in the Iberian Peninsula remain mainly unknown. We have developed new molecular markers for each species to be used in population genetics studies. Then, we characterized the genetic structure of the Iberian populations in order to infer their possible colonization routes. Our results show how the zebra mussel invasion into the Iberian Peninsula involves a single invasion episode with a separate colonization history than the rest of Europe. In Asian clam, our results revealed that at least two colonization episodes have occurred in the Iberian Peninsula. Finally, we have developed a genetic method based on environmental DNA for dreissenid larvae detection in waterbody samples, increasing the sensibility of the routinely zebra mussel larvae detection methods |
