Phytoplankton is almost universal in distribution but fluctuation in abundance depends on the surrounding environment, their consumer’s abundance influence with change in the environment. They are very sensitive to their environment, any change in their habitat may lead to the change in the planktonic communities in terms of tolerance, abundance, diversity and dominance in the habitat. Moreover, the physico-chemical properties and nutrient status of the water plays an important role in production of plankton, which is essential in maintaining healthy and productive aquatic organisms. The purpose of this study was to look into the seasonal variations in the species dynamics, diversity and abundance of phytoplankton in relation to some physico-chemical variables in Lower Lake of Bhopal. A total of 36 species of phytoplankton were documented of which 17 belongs to the group Chlorophyceae, 8 species represented by Cyanophyceae, 7 species belongs to Bacillariophyceae, Euglenophyceae (3 species) and only 1 species represents the whole group of phylum Pyrophyceae. Chlorophyceae recorded with highest number of species with a contribution of (47%), followed by Cyanophyceae recorded (22%), whereas (20%) of total phytoplankton was contributed by Bacillariophyceae which in turn followed by Euglenophyceae (8%) and (3%) Pyrophyceae. The present study revealed that cumulative seasonal diversity ranged from 22 to 33. The annual average ratio of Chlorophyceae, Cyanophyceae, Bacillariophyceae, Euglenophyceae and Pyrophyceae phytoplankton abundance in total was 37%, 21%, 13%, 22% and 7%, respectively. The average Chlorophyceae, Cyanophyceae, Bacillariophyceae, Euglenophyceae and Pyrophyceae abundance was 24227 units/l, 13583 units/l, 8701 units/l, 14165 units/l and 4341 units/l respectively.
