Average values (standard error) for the ENV factor of total abundance (a), total biomass (b), species richness (c), Shannon-Wiener diversity (d), Pielou evenness (e), Simpson dominance (f), AMBI-1 (g), AMBI-2 (h). The solid line in g and h represents the cutoff values for levels of disturbance according to AMBI: Undisturbed (blue, 1.2), Slightly disturbed (green, 3.3) and Moderately disturbed (yellow, 5.0)
