Physical characteristics and microbial communities in Lac Pavin. a Map showing the location of the meromictic Lac Pavin in the Auvergne region of central France. b Oxygen profiles across the lake water column during each of the three yearly samplings. Depths sampled on a given year are indicated with a dashed gray line, and colored shapes match those in panels c and d. c Principal coordinates analysis of microbial community composition at the “species group” level. d Microbial community composition in Lac Pavin at the phylum level, based on relative coverage of representative scaffolds encoding the ribosomal protein S3. Samples are ordered from shallow to deep, including the five sediment samples collected in 2019. N.B. For legibility, only the 15 lineages with the highest median abundance across all samples are shown, all others are indicated in gray as “other”. Abbreviations: PC, principal coordinate; var, variance; CPR, Candidate Phyla Radiation, WC, water column; SED, sediment
