Beta diversity analyses of microbial meta-community of the non-rhizosphere, the rhizosphere and rhizoplane of Baccharis linearis plants inhabiting abandoned tailings and surrounding soil. (A) Non-metric multidimensional scaling analysis of meta-community dissimilarities. Grouping by localization and root compartments was performed by estimation of the total beta diversity distances (βSOR) between samples. The localization and root compartment are denoted as follows: Huana tailings (blue), Tambillos tailings (dark grey), fresh tailings (green), surrounding soil (red), rhizoplane (filled circle), rhizosphere (x) and non-rhizosphere (□). Each point corresponds to a single T-RFLP profile (n = 4 replicates). (B) Density plots representing the distribution of the total beta diversity (βSOR), turnover (βSIM) and nestedness (βSNE) arising from multiple-site dissimilarity across the samples. Components of multiple-site dissimilarity were computed for microbial community composition (bacteria and fungi) in Huana (blue), and Tambillos (black) tailings and surrounding soil (red). ΒSNE: dashed line; βSIM: dotted line and βSOR: solid line. These figures were created using Betapart R Package Version 1.3. URL http://CRAN.R-project.org/package=betapart.
