Abstract
A study on zooplankton diversity and physicochemical conditions at Bommanahalli reservoir located in Kali tiger reserve was undertaken from July 2017 to September 2018. Water parameters like Atmospheric temperature, Water temperature, pH, Transparency, Conductivity, Suspended solids, Total solids, Hardness, Alkalinity, Chloride, Sulphate, and BOD were studied. A total of 31 zooplankton species were recorded. Rotifera was the dominant group represented with 11 species. Cladocera was the most abundant group with the highest number of individuals. Tropocyclopsprasinus was the most abundant species. Shannon’s and Simpson indices were found highest to Rotifera, while lowest for Ostracoda. Evenness was highest in Copepoda but Dominance was maximum for Ostracoda. Canonical Correspondence Analysis (CCA) indicates Cladocera and Rotifera show negative response to Water temperature were as Copepoda shows a positive response to Air temperature, EC and Turbidity.
