Because of their swift reaction to environmental changes, zooplankton biodiversity acts as an evolutionary measure of the marine climate. The effect of cyclic variations on zooplankton diversification was investigated in the Singanallur Lake located in Coimbatore, South India. On a seasonal basis, the ecology of zooplankton taxa was observed from December 2016 to November 2017. During this time period, 23 species of zooplankton were discovered, including 7 Rotifera and Cladocera species, as well as 5 Copepoda and Ostracoda species. The overall abundance of Rotifera was found to be prevalent with 35 percent in this study, led by Cladocera>Copepoda>Ostracoda. The mass of the population in different zooplankton groups was observed, and the order Rotifera>Copepoda> Cladocera>Ostracoda was discovered. Summer and early monsoon seasons saw the highest and lowest population densities, respectively. This Lake's temperature acceleration could be responsible for the higher zooplankton population density in the summer. The current study discovered that when the temperature in the Singanallur Lake was raised during the summer season, zooplankton productivity improved. This suggests that temperature has an effect on zooplankton diversity. As a result, rising temperatures as a result of global climate change could have an effect on zooplankton productivity. In the near future, assessing zooplankton ecology would be helpful in monitoring the health and resources of this lake system.
