Fig. 1

Effect size of agricultural land use on different organism groups accounting for different metric types. Shown are individual effect sizes per study, pooled effect sizes for two subgroups divided by metric type and an overall pooled effect size with 95% confidence intervals. Effect sizes are significant if 95% CI does not overlap the vertical zero line. Richness = species-, taxa richness; abundance = density, mass, count; ASPT Average core er taxa; IBI Index of biotic integrity, EPT Ephemeroptera, Plecoptera, Trichoptera, EQR Ecological quality ratio, O/E Observed/Expected, SPEAR Species at risk, WQ sensitive Water quality sensitivity index
