STUDIES ON PHYTOPLANKTON COMMUNITY WITH SPECIAL REFERENCE TO PHYSICO-CHEMICAL FACTORS IN BHALKI TANK, BHALKI, KARNATAKA, INDIAN. Shiddamallayya and M. Pratima
The abundance of phytoplankton community in a fresh water ecosystem was studied with special reference to physicochemical factors.The variation of nutrients, limiting factors and other physico-chemical factors in the water body regulated the abundance of different groups of algae. Influx of sewage from the city and runoff from the surrounding fields changed most in chemistry of water. Limiting factors with other factors monitored the abundance of Cyanophyceae and Chlorophyceae.Similarly, nutrients with other chemical factors controlled the population of Euglenophyceae and Bacillariophyceae.Temperature, pH, calcium, magnesium, chlorine, silicon, Sulphate, total solids and organic matter are the factors managed the phytoplankton community in the Bhalki tank, Bhalki.
