Correlation between molecular diversity and amphipods abundance or richness at each site. (a) Correlation between molecular diversity (as log number of ASVs) from the eDNA metabarcoding approach and the amphipod abundance from the citizen science approach (as log number of amphipods per day). The blue line shows the linear regression (y = 1.951x + 5.568) with the standard deviation in gray. (b) Correlation between molecular diversity (as log number of ASVs) from the eDNA metabarcoding approach and the amphipod richness from citizen science (as number of species). The blue line shows the linear regression (y = 0.571x + 5.133) with the standard deviation in gray.
