Relative abundance of EPT, water beetles larvae, and DSFI were negatively correlated with P total in sediments, whereas relative abundance of oligochaetes and molluscs showed an opposite trend in relation to P total in sediments (Table 3).
DSFI value was the highest in control sites and reliably differed from the value in HPP dams (ANOVA F = 11336.6,p =0.0001).
According to DSFI, water quality was classified as very good in the control sites, good below HPP dams and moderate in HPP dams.
The Danish Stream Fauna Index (DSFI), a modification of the Trent Biotic Index (Woodiwiss, 1964), served as the metric to estimate the level of organic pollution.
ASPT and NTAXA belong to the ordinary biological quality monitoring system in Great Britain (Wright, 2000), while DSFI is used in Denmark (Skriver et al., 2000).
For the calculation of DSFI, the identification level of the genus, family, or class is required, while ASPT and NTAXA are based on the family level.
ASPT and DSFI satisfied this condition but the residual distribution of NTAXA was close to a normal distribution only after logarithmic transformation.
To specify the influence of stream size on ASPT, NTAXA, and DSFI, four distance points (4, 25, 64, and 169 km from the stream source) were compared using tailored parametric functions.
Like bottom substrate, higher flow velocity revealed higher natural quality for ASPT and DSFI. Paradoxically, NTAXA was even somewhat higher for slower than for faster flow, although the difference was not significant in the sense of Bonferroni (Table 3).
The biological quality according to ASPT and DSFI was significantly influenced both by latitude and longitude (Table 3).
