Abstract

Phytoplankton diversity in Hadhinaru Lake of Mysore has been discussed. Five diversity indexes have been derived using the PASTA software program. They include, Shannon and Wiener index, Berger and Parker dominance index, Bellan and Santini index, Simpson index and Pielous evenness index. A total of 29 algal species were recorded during Dec. 2008 to Nov. 2009. Chlorococcales was recorded in higher nos., while Cyanophyceae and Desmidaceae were low in no. The evenness and dominance of species in the lake was not well marked. The lake becomes heavily polluted during March, May, Oct. and Nov. The Bray and Curtis Similarity index reveals that Euglena oxyuris, Cymbella cymbelliformis, Pinnularia gibba, Actinastrum hantzschii, Tetradron lobatum, Euglena elastica and Lepocinclis ovum have the highest similarity and can co-exist in a common cluster. Diversity indexes serve as an important tool in understanding the distribution of phytoplankton in lakes. [on SciFinder(R)]
