Flotsam, an overlooked vector of alien dispersal from ports

Anthropogenic litter is considered a potential vector for the dispersal of non-indigenous species (NIS) in marine ecosystems. Using the bay of Gijon (Southwestern Bay of Biscay) as a case study, we studied the composition and potential transfer of the communities inhabiting three different environme...

Using the bay of Gijon (Southwestern Bay of Biscay) as a case study, we studied the composition and potential transfer of the communities inhabiting three different environment components: 1) natural and artificial substrates from the international port of Gijon, 2) six proximate rocky beaches and 3) floating litter collected in the adjacent coast. A total of 717 organisms were morphologically identified and DNA barcoded using COI and 18S genes. In total 23 NIS were detected, six of them considered invasive in the area. The taxonomic profiles of the three environment components were significantly different, flotsam containing higher proportions of Hexanauplia and less mollusks, echinoderms and polychaetes than ports and beaches. Contrary to expectations, floating litter showed higher densities of native and exotic species than beaches or port surfaces. This and shared haplotypes between port, flotsam and beaches in some invasive species may indicate that marine litter could represent a new habitat for species to disperse into new areas.This study has been funded from the Spanish Ministry of Economy and Competitiveness Grant BLUEPORTS CGL-2016-79209-R and the Ministry of Science and Innovation Grant PDC2021-120939-I00.
