Figure 3 : Shannon diversity of each of the 34 samples (left) and boxplot of species richness, separated by non-rehabilitated (NR), rehabilitating (RH) and reference study sites (REF).

From: A metagenomic survey of soil microbial communities along a rehabilitation chronosequence after iron ore mining

Figure 3

Different letters in the same boxplot meant significant difference at 0.05 level according to a post-hoc Tukey HSD test. Although no significant difference in richness values between REF to NR and RH, we observed a significant difference between NR to RH.
