摘要:
Present study was based on diversity of Periphytic community on the different locations of the upper lake viz. (S1), (S2) and (S3) from the month of October, 2013 to December, 2013. Main work was on the habitat characterization of periphyton. Periphytometer are placed in the water body and left in place for a certain period of time which was used by us. It depends upon the rate at which periphyton accumulates on the substrate. As a rule, they should be removed just short of the point that the attachment surface becomes 'saturated' and periphyton begins sloughing off. At the end of the collection period, the periphyton is collected simply by scraping it off the surface. Periphytic communities are important structural and productive components of freshwater ecosystems; yet factors regulating their temporal and spatial abundance are difficult to predict. Another advantage of this method is that periphyton integrates water quality conditions over time, which may provide a better representation of lake water quality status than do instantaneous measures of specific constituents. At present there are total 122 species were present around the world but in my research I have found only 34 different species of this group. Our study also reveals the water parameters which indicates us the deteriorated condition of upper lake, due to constant growth of algal blooms at Bhopal, Madhya Pradesh. [ABSTRACT FROM AUTHOR]
