Fig. 3: Correlation heatmap for the PLFA profile of each biosampler, biofilm and the service water generated using Spearman’s rank correlation (ρ). More positive numbers (red) indicate a strong, positive correlation.

From: Deep terrestrial indigenous microbial community dominated by Candidatus Frackibacter

Numbers closer to zero indicate no correlation. More negative numbers (dark blue) indicate a weak negative correlation. The star (*) designates the biosampler that became detached from the borehole during sampling (*FW12261-2018).
