Figure 2.

Comparison of bacterial diversity between the different sampling points. (a) Cluster analysis of bacterial diversity at the phylum level using a correlation algorithm (the complement 1-r of Pearson's r correlation across the variables). (b) Stacked column graph representing the relative distribution of the dominant phyla in the different stations. The total number of sequence reads per sample is given left of the columns. (c) Stacked column graph representing the proteobacterial diversity. The double-headed arrow on top indicates the conditions with respect to salinity. Sample codes consist of the sampling station and the time point of sampling (Au, autumn; Sp, spring; Su, summer).
