Fig. 6: Relative abundance of selected a predicted degradation pathways and b DOM compound classes across wells.
From: Groundwater microbiomes balance resilience and vulnerability to hydroclimatic extremes
a Predicted degradation pathways inferred from 16S rRNA gene-sequences using PICRUSt2. b DOM compound classes derived from bulk DOM via DI-HRMS. Red horizontal lines denote the mean values across wells. Sample size for comparisons between hydrologically connected wells and more isolated wells are as follows: aromatic compound and amino acid degradation, n = 443 vs 247; condensed aromatic structure and peptide-like DOM compounds, n = 155 vs 71.
