Rank curves for 16S, 18S-V4, and 18S-V9. (a) log10–log10 relationship between mean abundance (reads) and abundance rank. (b) log10–log10 relationship between mean occurrence (samples) and occurrence rank. (c) log10–log10 relationship between mean occurrence (stations) and occurrence rank. Color indicates either 16S (pink), 18S-V4 (green), or 18S-V9 (blue) ASVs. Shading around the means (points) show the upper (95%) and lower (5%) percentiles of either abundance or occurrence, calculated from the 1000-member rarefaction ensemble. ASVs that were observed with an average of < 1 read, sample, or station were removed from these figures for improved clarity.
