“…The water samples were filtered in situ through PES Supor ® 200 Membrane Filters (Pall Corporation, Life Sciences) of 0.2 mm pore, and the filters were immediately placed in tubes filled with sterile ethanol. More details about sampling procedures can be found in Georges et al (2021).…”

“…QIIME software (Caporaso et al, 2010), although initially developed for prokaryote community analysis, is also employed on studies of eukaryote communities that use COI as a metabarcode (e.g., Von Ammon et al, 2018;Gueuning et al, 2019;Giebner et al, 2020;Georges et al, 2021). The open-source version QIIME 1.8.0 was employed in this study, as in Von Ammon et al ( 2018) and Georges et al (2021).…”

The movement of organisms facilitated by anthropogenic activities is a serious threat to marine diversity, especially for endemic species that may be outcompeted from non-indigenous species (NIS). In this study, we have analyzed communities inhabiting the north of the Gulf of Aqaba, Red Sea, employing environmental DNA (eDNA) metabarcoding. That gulf is especially rich in species and population endemism. We have detected NIS representing 36% of the total number of species found from eDNA. Primary producers were more abundant in the NIS than in the native fraction of species, suggesting that functional diversity could be altered if NIS thrive there. We discuss maritime traffic as a factor that may enhance the introduction of non-natives in this region and emphasize the importance of the control of these species that may threaten the rich endemic biota of the Red Sea.
