Estimated number of observed OTUs (at 97% similarity), richness, diversity, and coverage (n = 3, mean±SE)* of soil for each site.

n = number of replicates of each site*Different lowercase letters indicate statistically significant differences (POTUs, operational taxonomic units; Coverage, Good's nonparametric coverage estimator; ACE, abundance-based coverage estimator; Shannon, nonparametric Shannon diversity index; Simpson, nonparametric Simpson diversity index.Sites are designated by recovery time (years) or as undisturbed reference (UND).Estimated number of observed OTUs (at 97% similarity), richness, diversity, and coverage (n = 3, mean±SE)* of soil for each site.
