Spearman correlations between acidobacterial subdivisions and soil abiotic properties.

Colour of the square indicates type of correlation (shades of blue–positive; green to dark red–negative). ‘Other’ contain subdivisions with relative abundances below 1%. SD1 Unclassified and SD3 Unclassified contain Acidobacteriota OTUs with no taxonomic classification at genus level. EC–exchangeable cations, bs–base saturation.
