Figure 4. Graph representing null model distribution of Phylogenetic Species Clustering (nmdPSC).
(A) 16S Archaea and Bacteria, rDNA gene data; (B) Forward-Only ITS data. Dotted lines are showing nmdPSC significant values: >+2 is consistent with a sample that had more phylogenetic overdispersion than expected by chance alone, and nmdPSC value <−2 indicates more phylogenetic clustering than expected by chance alone; values in the range +2 and −2 had a null model distribution. nmdPSC values are reported in Table S7.
