Results of the two-way ANOVA applied on the diatom indices to evaluate differences among sampling methods (T vs MH) and HS attribute classes. Significant values are highlighted in bold.IPS (Specific Polluosensitivity Index); TI (Trophic Index); ICMi (Intercalibration Common Metric Index); HS (Hydrological Stability); T = traditional approach; MH = microhabitat.
