Community structure of benthic microalgae in the Cochin backwater from 10 s
elected stations were studied with special reference to indices of diversit
y (H'), richness (R1), Hill's diversity number (N1) and evenness index (E2)
. The correlation studies showed that the hydrographic parameters had signi
ficant influence on the distribution and composition of benthic microalgae
in the backwaters.
