Fig. 2From: Anaerobic methane-oxidizing bacterial communities in sediments of a drinking reservoir, Beijing, Chinaa Complete cluster analysis showing the differences in the 16S rRNA genes between summer and winter based on Bray Curtis distance. b Principal coordinate analysis (PCoA) for 16S rRNA gene assemblages using Bray Curtis distance. Bray Curtis distances were calculated using the relative abundance of the genes. The letter A represents 16S rRNA genes in summer, and the letter B represents the genes in winterBack to article page
