Effects of plant diversity and community age on soil microbial communities

This record contains supplementary information for the article "Effects of plant diversity and community age on soil microbial communities".

SI_tab_1_annotation.ods: Taxonomic annotations of the operational taxonomic unit (OTU) identified in the study.

SI_tab_2_counts.ods: Number of reads per OTU and sample.

SI_tab_3_enrichment.ods: The table contains all phyla tested for enrichment/depletion in sets of differentially abundant OTUs. "Contrast" indicates the differential expression contrast. "Observed" corresponds to the number of OTUs annotated with a given phyla in the set of differentially abundant OTUs. "Expected" gives the number of OTUs which would be expected to be annotated with a given phyla if the test set were randomly sampled from the reference set.

SI_tab_4_anova_indices_legumes.ods: Analysis of variance of microbial richness (number of OTUs), effective richness (exp(Shannon Index)) and Pielou’s evenness. Contrasts among soil-legacy treatments and their interactions are indented. isMonoculture: a contrast to compare plant monocultures to plant species mixtures, logSR: log2 of plant species richness, hasLegumes: contrast for presence/absence of legumes, SL: soil legacy, AGE: new soil compared to the two other soils, INO: inoculated compared to native soil, PA: plant community age.

SI_tab_5_permanova_unifrac_grasses.ods: Multivariate analysis of variance of dissimilarities between microbial communities. Contrasts among soil-legacy treatments and their interactions are indented. MS refers to the mean squares of the dissimilarity measure (Unifrac distances). isMonoculture: a contrast to compare plant monocultures to plant species mixtures, logSR: log2 of plant species richness, hasGrass: contrast for presence/absence of grasses, SL: soil legacy, AGE: new soil compared to the two other soils, INO: inoculated compared to native soil, PA: plant community age.

SI_tab_6_permanova_legumes.ods: Top: As S5, but with Manhattan distances of log2(x+1) transformed sequence counts instead of unifrac distances. Bottom: As S5 but with legumes instead of grasses.

SI_tab_7_soilChemistry_grasses.ods: Analysis of variance of soil chemistry. isMonoculture: a contrast to compare plant monocultures to plant species mixtures, logSR: log2 of plant species richness, hasGrasses: contrast for presence/absence of grasses, SL: soil legacy, AGE: new soil compared to the two other soils, INO: inoculated compared to native soil, PA: plant community age.
