Abstract


The study pertains to the diversity patterns of periphytic algal assemblages of seven springs subjected to different anthropogenic stresses. The periphytic algal community during September 2010 to August 2011 revealed a total of twenty three species belonging to three algal classes: Chlorophyceae (6), Bacillariophyceae (12) and Cyanophyceae (5). The most dominant species in the algal community were Rhizoclonium sp., Diatomella balfuriana, Navicula sp., and Oscillatoria limosa. During the present study maximum number of species was obtained at Dubnagin (23), followed by Naranag (19), Parinag (17), Himalinag (15), Malakhnag (10), Batnagin (10) and decreasing to the minimum of 9 species at Kirkadalnag. Among the various periphytic classes, Bacillariophyceae dominated qualitatively both in diversity and density at each spring being followed by Chlorophyceae and Cyanophyceae.
