Figure 1.
Abundances of archaeal and bacterial amoA genes in the surface sediment samples treated with different temperatures.
Data are shown as Means±SD (n = 3). Different uppercase (archaeal amoA gene) and lowercase letters (bacterial amoA gene) refer to significant differences between different temperature treatments (P<0.05).

Figure 2.
Phylogenetic trees of the archaeal (A) and bacterial (B) amoA gene sequences.
Sequences obtained in this study were written in bold and colors, which represent different clone libraries (Red: 0 d; pink: 15°C treatment; blue: 25°C treatment; green: 35°C treatment). One representative sequence from each OTU is shown in the phylogenetic trees. Numbers in parentheses indicate the number of sequences affiliated to the same OTU. Bootstrap numbers >50% are shown.
