FIGURE 4

Relative abundances (%) of 16S rRNA sequence tags from AOA, AOB, NOB and COMAMMOX groups in surface (A) and deep sediments (B) during initial conditions (i.e., 0 weeks) and after the different DPDs with no rainfall (i.e., 0 mm selected). Number of copies of amoA genes for AOA and AOB in surface (C) and deep sediments (D) during initial conditions and after the different DPDs with no rainfall. Asterisks () denote significant (P ≤ 0.05) differences to initial wet conditions after Student’s t-test followed by Holm’s correction for multiple comparisons. Values are means ± SE (n = 3).
