In this study carried out in North Iberian ports (Cantabrian Sea, Bay of Biscay) we have observed 38% of exotic macroinvertebrates. Four species, namely the barnacle Austrominius modestus, the tubeworm Ficopomatus enigmaticus, the Pacific oyster Crassostrea gigas and the pygmy mussel Xenostrobus securis, exhibited clear signs of invasiveness. A total of 671 barcode (cytochrome oxidase subunit I or 18S rRNA) genes were obtained and confirmed the species status of some cryptic NIS. Negative and significant correlation between diversity estimators of native biota and proportion of NIS suggests biotic resistance in ports. This could be applied to management of port biota for contributing to prevent the settlement of biopollutants in these areas which are very sensitive to biological invasions.engjournal article1879-3363https://doi.org/10.1016/j.marpolbul.2016.08.022https://www.sciencedirect.com/science/article/pii/S0025326X16306543?via%3Dihubrestricted access592575.858591.9(26)Non-indigenous speciesBiotic resistanceMarine biological invasionsDNA barcodingPortsBiología marinaInvertebrados2401 Biología Animal (Zoología)2401.17 Invertebrados2401.19 Zoología Marina2401.08 Genética Animal
