Heat-map of the Pearson correlations of beta-proteobacteria (Bet), alpha-proteobacteria (Alph), Cytophaga-Flavobacteria (CF), Eubacteria excluding Alph, Bet and CF (EUBI-III(undef)) and not-defined DAPI positive cells (ND) to physico-chemical variables.

Asterisk indicate the p-value (*: p<0.05; **: p<0.01; ***: p<0.001) of correlations between paired samples.
