Performance of eDNA/eRNA metabarcoding analysis in ecological surveys of arthropods and algae. Sensitivity and positive predictivity of metabarcoding analysis for (A) arthropods and (B) algae. eDNA/eRNA: eDNA/eRNA metabarcoding analysis, quant.: quantitative analysis, qualit.: qualitative analysis. Dots indicate the performance when individual data are merged. The values represent the mean + standard deviation (SD). Different letters indicate significant differences (Tukey–Kramer test). The values represent the mean + standard deviation (SD). Arcsine transformation did not change the letters.
