摘要：Phytoplankton diversity in four surface water samples from Coorg district i.e., Kaveri Nisargadhama, Abbeyfalls, Bhagamandala and Talakaveri of Karnataka state and two samples from Wynad district i.e., Irrity river and Pazhassidam of Kerala state belonging to western ghats were studied for the year 2011 and 2012 and discussed in the paper. Sixclasses of 53 species of phytoplanktons were identified viz., Bacillariophyceae, Chlorophyceae, Cyanophyceae,Desmidaceae, Euglenophyceae and Ulvophyceae. Bacillallariophyceae group dominated followed by Desmidaceae,Chlorophyceae, Euglenophyceae, Cyanophyceae and Ulvophyceae. Members of Bacillariophyceae formed blooms inAbbey falls, Bhagamandala and Pazhassi dam which often lead to eutrophication. The evenness and dominance of speciesin the lake was not well marked. An experiment was also set up to see the formation of algal blooms from the same surfacewater samples and to identify whether same group of species are identified which is responsible in the formation of algalblooms. Hence it has become essential to develop conservation strategies for control of lakes based on the diversity andabundance of phytoplankton blooms.
