Algal Diversity in a Group of Fifteen Small Lakes of T. Narasipur Taluk, Mysore District, Karnataka State
Phytoplankton distribution was investigated in 15 small lakes of T. Narasipur taluk in Mysore district of Karnataka. The data were subjected to PAST software program. Bray-Curtis Similarity Index was also calculated. Nine diversity indices were obtained that include Dominance index, Shannon and Weiner index, Simpson's index, Pielou's Evenness index, Menhinick and Margalef's index, Equitability index, Fisher α index and Berger-Parker dominance index. Sixty two species of algae were recorded of which Chlorococcales and Euglenophyceae members dominated. Species richness was observed in Harave Katte and Baw Kere, and species dominance in Holan Kere and Halgudu Kere. Diversity and Similarity indices are important in understanding the distribution and association of planktonic algae in freshwater lakes.
