Marine Subsurface Microbial Community Shifts Across a Hydrothermal Gradient in Okinawa Trough Sediments

Table 1

Bivariate correlation values of environmental variables with significant correlation to dominant taxa (second column); taxa that have significant correlations with one another (third column); and environmental variables that have significant correlation with depth (bottom row). The chemical species abbreviation or taxon name is listed with the correlation value in parentheses. All correlation values listed here are significant at the 0.01 level (2-tailed).
