Extended Data Fig. 3: Variation of bacterial alpha diversity along the stress gradient.
From: Environmental stress mediates groundwater microbial community assembly
a, Richness estimated by iChao1 index; b, Shannon index. The line and shadow show the trendline and 95% confidence interval based on linear regression. r and P are Pearson correlation coefficient and significance (two-sided). The significant Pearson correlation indicates a general decrease in bacterial richness as stress increased in the groundwater.
