Abstract The increasing prevalence of non-indigenous species (NIS) in marine ecosystems poses significant challenges for biodiversity conservation and ecosystem management. Advances molecular techniques enable early detection long-term monitoring such taxa, especially when coupled with spatio-temporally wide sampling by networks as the European ARMS Marine Biodiversity Observation Network (ARMS-MBON). This initiative performs standardised campaigns using autonomous reef structures (ARMS) along coasts adjacent regions, providing open-access DNA metabarcoding data sets. We tested potential genetic observatory to detect monitor NIS analysing all publicly available ARMS-MBON cytochrome c oxidase subunit I (COI) 18S rRNA amplicon sequencing February 2024 a customised bioinformatic pipeline. Screening against World Register Introduced Species (WRiMS) applying manual curation, we identified 63 taxa considered at one or more locations. included widespread new introductions, Eucheilota menoni Adriatic Sea. found no significantly higher number samples from locations particularly impacted maritime traffic compared other areas. Our results suggest that network approach is powerful detecting NIS, curation still an essential step obtaining reliable results. recommend key improvements including spatially intense across diverse environments well enhancement reference checklists databases ensure accurate identification both known unknown Europe.

Recent research efforts to mitigate the burden of biofouling in marine environments have focused on development environmentally friendly coatings that can provide long-lasting protective effects. In this study, antifouling performance novel polyurethane (PU)-based containing cyclam-based Fe(III) complexes against Cobetia marina biofilm formation was investigated. Biofilm assays were performed over 42 days under controlled hydrodynamic conditions mimicked environments. Colony-forming units (CFU) determination and flow cytometric (FC) analysis showed PU-coated surfaces incorporating 1 wt.% with formula [{R2(4-CF3PhCH2)2Cyclam}FeCl2]Cl (R = H, HOCH2CH2CH2) significantly reduced both culturable total cells C. biofilms up 50% H) 38% compared surface without (control surface).

The Mediterranean Sea is considered a hotspot for bioinvaders. Nonetheless, information on non-indigenous benthic foraminifera still fragmented. This study documents the first time presence along northwestern Adriatic coast of species Virgulinella fragilis, Grindell and Collen (1976). Due to low abundance recorded in area, this may represent an early colonization phase. We discuss temporal spatial patterns V. fragilis arrival Seas, we hypothesize stowaway transport (via ship fouling or ballast water) as main introduction pathway.
