Supplementary figure 2. Correspondence between beta-diversity (community difference)
and (absolute) difference in salinity and temperature. (A,C) Bacterial communities. (B,D)
Eukaryotic communities. Each circle is one pair of samples. The Spearman correlation coefficient
(rho) is indicated in each plot.
