Fig. S1. Effect of pCO2 concentration on the average OTU abundance of the phylum Planctomycetes (A) and the class Halobacteria (C) and on the average relative abundance of the classes Planctomycetacia (▲) and Nitrospira (□) (B). Error bars are standard error (n = 4).

Table S1. Pearson's correlation coefficients calculated for pCO2 concentration and relative abundance of classes. Also shown is the relative abundance of each class. Highlighted are those classes that had relative abundance values greater than 1% and in red are those classes which correlated with changes to pCO2 concentration. Significant statistical differences between all treatments are indicated by ** for P ≤ 0.01 and * for P ≤ 0.05.
