FIGURE 3

Taxonomic composition of archaeal communities based on 16S rRNA gene sequencing. Samples were divided into MIS 1, MIS 2, and MIS 3, and two stages based on the terrestrial input intensity derived from n-alkane C31 [minus sign (–), low terrestrial input; plus sign (+), high terrestrial input]. The similarities were analyzed by ANOSIM (*P < 0.01, N.S = not significant).
