Figure 3. Alpha-diversity analysis using rarefaction (A) and phylogenetic diversity (B) of contaminated and control soils.

Figure 3

Each soil is represented by color and pattern. Rarefaction analysis focuses on discovery of novel species level (97%) Operational Taxonomic Units (OTUs) while phylogenetic diversity focuses on the discovery of novel phylogenetic branches.
