Spatio-temporal metabarcoding surveys in ports reveal homogenised communities of non-indigenous species with high genetic diversity and connectivity.

Abstract excerpt

Large commercial ports facilitate the introduction of non-indigenous species (NIS), while smaller harbours and marinas promote their regional spread, making harbour networks key drivers of biological invasions. We analysed spatio-temporal patterns of metazoan communities over one year in four medium-size harbours, as well as at an outside reference point, along the NW Mediterranean coast using standardised...
