Figure Lengend Snippet: Sediment community structure of methanogenic genera given by 16S rRNA gene amplicon sequences at Bonete (B) and Palmar (P) reservoirs. (a) Principal Coordinates Analysis (PCoA) with Bray-Curtis distance, at taxonomic ASV level, from triplicate sediment samples at three sites in the Bonete reservoir (red) and three sites in the Palmar reservoir (cyan) sampled in autumn (circles) and spring (triangles); (b) significant ( p < 0.05) differential abundance of methanogenic genera according to reservoir, where the values ( n ) on the axis indicate a 2-fold (FC: fold change) increase (by 2 n times) of a genus in one reservoir compared to the other; c) relative abundance of methanogenic genera in archaeal sequences in three sites of Bonete and three sites of Palmar reservoirs from sediments collected at autumn (A) and spring (S).
