Fig. 2 — A Bulk enrichment of ¹³C in DNA extracted from incubations amended with ¹³C-labeled aspartate. The X-axis represents fractions from a cesium chloride density gradient. Significant correlations as determined by Spearman’s rank test are denoted by an asterisk (p < 0.05). B Venn diagram depicting the number of amplicon sequence variants (ASVs) that assimilated ¹³C-acetate, ¹³C-aspartate, or both, displaying a high degree of resource partitioning (chi-square test of independence, p < 0.001).
