Figure S4 from Beyond the visual: using metabarcoding to characterize the hidden reef cryptobiome

Environmental drivers of indicator OTUs. Indicator OTUs (colored by region: Light Green – North; Blue – Central; Dark Green – South) and the relative importance of the measured environmental variables (darker colors indicate higher relative importance). Significant positive (+) and negative (-) correlations between the abundance of the OTU and the environmental variable are depicted. NS: non significant.
