Note: The abbreviation ‘Df’ means degrees of freedom. Asterisks and dot indicate statistical (*** P < 0.001; ** P< 0.01; * P < 0.05) and marginal (P< 0.1) significances of the fixed effects. The posterior means in the fixed effect ‘Assay’ were estimated against the studies collecting eDNA by filtration. The posterior means in the fixed effect ‘Taxa were estimated against the studies targeting fish species. The posterior means in the fixed effect ‘Environment were estimated against the studies performing in laboratory conditions. The posterior means in the fixed effect ‘Metrics were estimated against the studies using species biomass as an abundance metrics.
