Figure 2. Non-metric multidimensional scaling (NMDS) of the bacterial community structure and the environmental variables.

Figure 2

Ordination of samples based on the weighted UniFrac distance from the community structure and their relationship with the physicochemical variables. Shallow sites included samples collected from 20 to 600 m, and deep sites from 2,800 to 3,700 m depth. Physicochemical variables related to the bacterial community structure are shown in green arrows. TS total sulfur concentration. NMDS stress value = 0.0684.
