Table 6 Results of stepwise multiple linear regression coefficients of the environmental influence on the community-wide metrics

Metric	Standardized coefficients	p	r ² _adj.
CR	0.6 fish complexity	< 0.01	0.39
NR	-0.8 salinity - 0.6 TDP	< 0.01	0.64
TA	0.8 fish complexity	< 0.01	0.67
CD	0.7 fish complexity	< 0.01	0.50
NND	0.7 DOC - 0.6 Chl a	< 0.01	0.54

See Table 4 for abbreviations of community metrics. Standard deviation of NND was not significantly correlated to any of the environmental variables
