Genomic variation in Ca. Regnicoccus frigidus population. Circos plots depict the distribution of relative coverages of genes in a MAG-AL1 and b MAG-AL2, in merged metagenomes from various Ace Lake depths and time periods (see Additional file 1: Table S4 for merged metagenome descriptions). The x-axes are shown on the outermost annuli: beginning of every contig, red tick; 10 kb length, grey tick. The annuli are first segregated by lake depth (surface, 0 m; oxic 1, 5 m; oxic 2, 12–13 m; interface: 13–15 m; anoxic 1, 14–16 m; anoxic 2, 18–19 m; anoxic 3, 23–24 m) and then arranged by season (summer: Jan, Dec; winter: Jul, Aug; spring: Oct, Nov). Metagenome reads with ambiguous mapping were allowed to map to the first best site, resulting in coverages of genes with multiple copies exceeding 100%; for display purposes, coverage was capped at 120%. Outer to inner annuli: MAG-AL1 contigs 1–64 or MAG-AL2 contigs 1–120; 0 m: 27 Jan 2015; 5 m: Dec 2014, Jul 2014, Aug 2014, Nov 2008 and Oct 2014; 12–13 m: Dec 2014, Jul 2014, Aug 2014, Nov 2008, Nov 2013 and Oct 2014; 13–15 m: Dec 2014, Jul 2014, Aug 2014, Nov 2008, Nov 2013 and Oct 2014; 14–16 m: Dec 2014, Nov 2008, Nov 2013 and Oct 2014; 18–19 m: Dec 2014, Nov 2008, Nov 2013 and Oct 2014; 23–24 m: Dec 2014, Nov 2008, Nov 2013 and Oct 2014
