Results of indicator species analysis.

<p>For each of the taxa, we indicate the total number of sequences corresponding to the OTU that represents the specific groups of samples (size), the Indicator Value index (IndVal), the number of samples that contain the taxon (Freq), the statistical significance of the association (p-value), the chance of reporting a false-positive result (q-value), and the lowest taxonomic rank assigned with a bootstrap confidence greater than 80%. Agricultural managements GAP and PAP are defined in the main text. Results were sorted according to Size. Only OTUs containing 20 or more sequences are shown in this table. See <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0051075#pone.0051075.s009" target="_blank">Table S6</a> for a complete list of significant indicators with IndVal values ≥0.75.
