Rarefaction curves were determined using clustering at 95% of similarity.

emi412126-sup-0003-si.tif5437KFig. S3. Bacterial-ARISA profiles obtained after 10, 20, 40 and 80 days of incubation for the level of diversity D0. For each sampling date, three replicates of control soils (Ct) and soils spiked with mercury (Hg) were prepared. Arrows indicate significant modifications between profiles (e.g. common bands with different relative abundance).
