Fig. 7: Beta-diversity of communities from gas hydrate mounds.
From: Distinct methane-dependent biogeochemical states in Arctic seafloor gas hydrate mounds
Principal Coordinates Analysis (PCoA) ordination of weighted Unifrac distances between all communities, colored according to states of methane dynamics (a), and redox zones within the sediment column (b). A Hellinger transformation was applied to ASV count tables before calculating the distance matrix. PERMANOVA tests verify distinct community structures present across states and redox zones, with R2 and p-values shown in corresponding plots. SR sulfate reduction, SMT sulfate-methane transition.
