Zooplankton Composition, Diversity and Physicochemical Features of Bandam Kommu Pond, Medak District, Telangana, India

Zooplankton Composition, Diversity and Physicochemical Features of Bandam Kommu Pond, Medak... The present investigation aims to study the zooplankton composition, diversity along with physicochemical profile in a chosen pond at Medak district from December, 2010 to November, 2012. The study revealed the occurrence of 80 zooplankton species including 60 rotifers, 18 cladocerans and 02 copepods. Zooplankton density fluctuated between 119 and 26,463/L, diversity H′ = 0.89–2.68, species richness 5–21 and dominance 18.6–74.1 % over the 2 years study period. Rotifers were more predominant than other zooplankton communities, especially family Brachionidae and Lecanidae. High density of the overall zooplankton community was due to more rotifer population and the numerical dominance of the species Brachionus angularis, B. calyciflorus, B. caudatus, Keratella tropica, Filinia terminalis and Epiphanies mucronata. It was observed that the zooplankton density significantly correlates with pH values of the pond. Physicochemical profile of the pond shows tropical climate, hard water and alkaline in nature. Chloride content was found to be high may be due to the anthropogenic pressure and influx of sewage. The high content of phosphate and nitrate reveals that the pond is enriched with nutrients. This has significant correlation with zooplankton dominance. The present findings clearly indicates the eutrophication of the pond. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Proceedings of the Zoological Society Springer Journals

Abstract

The present investigation aims to study the zooplankton composition, diversity along with physicochemical profile in a chosen pond at Medak district from December, 2010 to November, 2012. The study revealed the occurrence of 80 zooplankton species including 60 rotifers, 18 cladocerans and 02 copepods. Zooplankton density fluctuated between 119 and 26,463/L, diversity H′ = 0.89–2.68, species richness 5–21 and dominance 18.6–74.1 % over the 2 years study period. Rotifers were more predominant than other zooplankton communities, especially family Brachionidae and Lecanidae. High density of the overall zooplankton community was due to more rotifer population and the numerical dominance of the species Brachionus angularis, B. calyciflorus, B. caudatus, Keratella tropica, Filinia terminalis and Epiphanies mucronata. It was observed that the zooplankton density significantly correlates with pH values of the pond. Physicochemical profile of the pond shows tropical climate, hard water and alkaline in nature. Chloride content was found to be high may be due to the anthropogenic pressure and influx of sewage. The high content of phosphate and nitrate reveals that the pond is enriched with nutrients. This has significant correlation with zooplankton dominance. The present findings clearly indicates the eutrophication of the pond.
