Variation of the abundance of microbial metabolic groups. Variation of the abundance of microbial metabolic groups (%) in sediment, water, and riparian soil in high-flow period with respect to low-flow period at each Suquía River study sites. (A) Variation of total aerobic heterotrophs. (B) Variation of fermenters. (C) Variation of sulfate reducers. (D) Variation of nitrate reducers. (E) Variation of ammonifiers. (F) Variation of cellulolytics. Asterisk indicates significant abundance increases or decreases in high-flow period for each study site. RS, reference site; S1, site 1; S2, site 2; S3, site 3; S4, site 4; and S5, site 5.
