Mi. Romero et M. Onaindia, FULLGROWN AQUATIC MACROPHYTES AS INDICATORS OF RIVER WATER-QUALITY INTHE NORTHWEST IBERIAN PENINSULA, Annales botanici Fennici, 32(2), 1995, pp. 91-99
We studied the distribution of aquatic macrophytes with respect to phy
sicochemical characteristics of water in rivers of Galicia (northwest
Iberian Peninsula). Of the 27 species found at 43 sampling sites, 17 s
howed a statistically significant correlation with at least one of the
17 physicochemical variables considered. Of these, we consider 14 spe
cies to be useful indicators of particular aspects of water quality.
