Abstract
Seasonal changes in the algal diversity with respect to phosphorus load from sewage and dyeing effluent in a small eutrophic reservoir was investigated for a year with monthly samplings. An increase in phytoplankton count was observed (R2 0. 6) with rise in Phosphate concentrations. Maximum algal diversity (Shannon Simpsons diversity indices richness and evenness) was observed during summer April to July when phosphate concentrations were at moderate level (0.074-0.163 mgL-1 ). Excessive phosphate influx (1.060-1.170 mgL-1) during rainy season September to November caused blooms of nonheterocystous assemblage of desmids particularly of Cosmarium sp and myxophycean species and a general decrease in algal diversity indices was observed.
