Detection and characterisation of the biopollutant Xenostrobus securis (Lamarck 1819) Asturian population from DNA Barcoding and eBarcoding
DNA efficiently contributes to detect and understand marine invasions. In 2014 the potential biological pollutant
pygmy mussel (Xenostrobus securis)was observed for the first time in the Avilés estuary (Asturias, Bay of Biscay).
The goal of this study was to assess the stage of invasion, based on demographic and genetic (DNA Barcoding)
characteristics, and to develop a molecular tool for surveying the species in environmental DNA. A total of 130
individuals were analysed for the DNA Barcode cytochrome oxidase I gene in order to determine genetic
diversity, population structure, expansion trends, and to inferring introduction hits. Reproductionwas evidenced
by bimodal size distributions of 1597 mussels. High population genetic variation and genetically distinct clades
might suggest multiple introductions from several source populations. Finally, species-specific primers were
developed within the DNA barcode for PCR amplification from water samples in order to enabling rapid detection
of the species in initial expansion stages
