| Description: |
International audience ; Environment al DNA (eDNA) met abarcoding is a method to detect t axa from environment al samples. It is increasingly used f or marine biodiv ersity surv e y s. As it only requires water collection, eDNA metabarcoding is less in v asiv e than scientific trawling and might be more cost effective. Here, w e analy sed data from both sampling methods applied in the same scientific surv e y targeting Northeast Atlantic fish in the B a y of Biscay. We compared the methods regarding the distribution of taxonomic, phylogenetic, and functional diversity. We found that eDNA captured more taxonomic and phylogenetic richness than bottom trawling and more functional richness at the local scale. eDNA was less selective than trawling and detected species in local communities spanning larger phylogenetic and functional breadths, especially as it detected large pelagic species that escaped the tra wl, e v en though trawling detected more flat fish. eDNA indicated differences in fish community composition that were comparable to those based on tra wling. Ho w e v er, consistency betw een abundance estimates pro vided b y eDNA metabarcoding and trawl catches was low, even after accounting for allometric scaling in eDNA production. We conclude that eDNA metabarcoding is a promising method that can complement scientific trawling for multi-component biodiversity monitoring based on presence/absence, but not yet for abundance. |
