Table 2.
Analysis of the occurrence of taxa across site conditions. The square root of the indicator value (IndVal) of the most significative taxa is presented. Components of the IndVal, specificity (A) and fidelity (B), are shown as well. Condition groups are defined as acidic (A), circumneutral (N), thermophilic (T) and hyperthermophilic (H), with combinations being considered.
