Diversity of phytoplankton and aquatic Macrophytes in Amruthapur lake of Nizamabad district in Telangana

Phytoplanktonic algae and aquatic macrophytes play dynamic role in fresh water ecosystem. The lake, locally called as Amruthapur lake is located in the vicinity of Telangana University campus, Amruthapur village, Dichpally. This lake was chosen to enumerate diversity of phytoplankton’s and distribution of aquatic macrophytes by seasonal variation for which collections were analyzed for a period of one year during August, 2014-October, 2015. For experimental studies surface and bottom water samples were collected from differenent sites of Amruthapur lake. The observations revealed that Amruthapur lake showed more abundance of phytoplanktonic algae belonging to class Chlorophyceae, Bacillariophyceae and Cyanophyceae.
