(A) Percentage of the abundant, intermediate, and rare reads and OTUs across all samples. (B) Percentage of the abundant, intermediate, and rare OTUs in transition among the three biospheres across all samples. For example, to test whether the intermediate group was stable or shifted between the abundant and rare groups across all samples, the numbers of OTUs belonging to the abundant, intermediate and rare groups in the intermediate OTU table were counted separately and then divided by the total number of OTUs to calculate the proportion of each group represented in the intermediate biosphere. (C) Average relative abundance of common OTUs occurring in both rRNA and rDNA datasets. The abundance thresholds for abundant (>1%) and rare (<0.01%) are indicated with horizontal and vertical lines. The best-fitting linear regression which was a relatively Y-axis deviated 1:1 relationship.
