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.
