Metabolisms of the most highly abundant MAGs in Bundera Sinkhole as noted in Fig. 7. Estimated genome completeness is displayed within square brackets under each MAG ID. Pie charts indicate the proportion of reads at each depth that map to the four MAGs. Metabolic reactions are labelled in red text, proteins mediating those reactions are labelled in black text, and the reaction products/substrates are labelled in blue text. Bar charts indicate the dissolved oxygen (DO) and salinity at each depth. In MAG-107, ammonia oxidation is displayed as a dashed arrow, as the amoA gene was not originally binned with this MAG. However, it was included here after detecting an amoA gene, taxonomically classified as Nitrosopumilus, that had a relative abundance almost perfectly correlated (r.2 = 0.97, p = 1.084e − 08) with that of MAG-107
