From: The methane-driven interaction network in terrestrial methane hotspots
Redundancy analysis (RDA) showing compositional differences of the metabolically active bacterial community (13C-enriched 16S rRNA gene diversity) from widespread methane hotspots, and the variables (inorganic N, sulphate, pH, EC, total N and C, methane uptake rates, and pmoA gene abundance) affecting the community as constraints. Significant (p < 0.01) variables affecting the community composition are emboldened (EC, total C and N). Abbreviations: EC, electrical conductivity; pmoA, pmoA gene abundance as proxy for methanotroph abundance
