Fig. 7From: Anaerobic methane-oxidizing bacterial communities in sediments of a drinking reservoir, Beijing, ChinaRedundancy analyses (RDA) of 16S rRNA (a) and nutrient variables in summer and winter. Redundancy analyses (RDA) of pmoA genes (b) and nutrient variables in summer and winter. Correlations between environmental factors and RDA axes are represented by the length and angle of arrows.
