Figure 3:

18S rRNA amplicon sequencing of global high-throughput sequencing datasets.

Number at top of histogram indicates the number of samples used in this analysis. Numbers at top of histogram do not match the total number of databases analyzed, as many samples had no fungal sequences remaining after subsampling. (Top) Histogram of lowest-level classification of marine fungal taxa using SILVA-classified datasets from various regions of the world. (Bottom left) Non-metric multidimensional scaling (NMDS) spatial analysis of normalized sequencing datasets displaying color-coded sites with embedded colors representing sites from deeper (>35 m) and shallower depths. (Bottom right) Rarefaction curves showing the number of fungal genera detected as a function of the number of fungal sequences analyzed before database normalization.
