Phytoplanktonic Diversity and Its Relation to Physico-chemical Parameters of Water at Dogarwada Ghat of River Narmada

Abstract

Present study was undertaken to assess the spatial and temporal distribution of phytoplanktons with respect to the changes in various physico-chemical parameters of Dongarwada ghat of river Narmada Madhya Pradesh. The study was carried for a year from March 2010 to February 2011.The results revealed presence of total of 27 taxa of phytoplanktons belonging to 4 families were found in order of Chlorophyceae (47%) >Cyanophyceae (27%) >Bacillariophyceae (23%)>Euglenophyceae (3%).Diversity parameters such as Shannon index ranged from 1.092-0.37, Simpson index from 0.6622-0.6202, evenness diversity index ranged from 0.9932 -0.7288 and Margelef index between 0.5459-0.2951.Various physico-chemical parameters of water analyzed depicted a positive correlation with diversity and distribution of Phytoplankton.
