Distribution and Diversity of Chlorophyceae in Saroornagar Lake, Hyderabad

Abstract

The present paper deals with the study of Chlorophyceae in Saroornagar Lake. Samples were collected from four sampling stations for a period of two years and comprehensive physico-chemical analysis was carried out. Linear multiple regression analysis (MRA) has been carried out in evaluating the importance of various physico-chemical variables on the growth and development of Chlorophyceae with SPSS software. The physico-chemical parameters played an important role in distribution and diversity of algae. Higher peaks of green algae were reported during summer and were represented by Chlorella vulgaris, Ankistrodesmusfalcatus, Scenedesmus sp. and Coelastrummicroporum. The species of Ankistrodesmusfalcatus, Chlorella vulgaris and Scenedesmus sp., Pandorinamorum, Actinastrumhantzchii, Pyrobotrysincurva and Micractiniumpusillum confirm eutrophic condition of the lake and act as indicators of organic pollution and represent pollution tolerant species. The indicator species of Chlorophyceae were represented by microphotographs.
