Distribution and ecology of diatom communities in four la kes using Lange-Bertalot method

An anthropogenic change in the ecology of lakes is very common. These physical, chemical, and biological changes have resulted in the loss of biological integrity in Lakes. Changes in the biological communities of these habitats have included long term alteration of diatom community structure (Herdendorf, 1989). Desikachary (1962), Ghosh and Gaur (1993), Juttner et al., (1996), Nautiyal and Nautiyal (1999); Karthick et al., (2009) have given more attention towards the distribution and periodicity of diatoms.
