Anjali Tomar and B.P.S. Chauhan

Abstract :

Studies on the algal diversity of river Yamuna at Agra revealed the presence of 15 algal Genera and 20 species of chlorophyceae has been identified from selected sites by their appearances such as shape and colour of the thallus. The phenology of freshwater algae mostly belonging to chlorophycean members is totally dependent on the physico-chemical characteristics of the water bodies. Maximum algal population was noticed in early summer, followed by winter, while the lowest in august. The amount of water discharge velocity and transparency influence the occurrence and abundance of algal diversity. During summer and winter time, certain species of chlorophyceae group were recorded as dominant species e.g. Chlorella vulgaris, Pediastrum sp., Spirogyra sp., Scendesmus sp., Chara sp., Volvox sp., Cladophora sp., Closterium cynthia, Zygnema sp., Pendorina sp.and Chlamydomonas sp. etc.
