Fig. 4: Abundance and predicted optimal growth temperature of the 325 Auka MAGs.

Scatter plots showing reads per million base pairs of the Auka MAGs, as a proxy for organism abundance, in the sampled cores with point color corresponding to predicted optimal growth temperature (OGT) of each MAG. The dashed line represents equal abundance between both samples. A Comparison of MAG abundance between the DR750-PC67 surface horizon (0–7 cm) and DR750-PC67 deep horizon (7+ cm). B Comparison of MAG abundance between the DR750-PC80 surface horizon (0–7 cm) and DR750-PC80 deep horizon (7+ cm). C Comparison of MAG abundance between the surface horizons of both cores. D Comparison of MAG abundance between the deep horizons of both cores.
