Measurement for Diversity Indices of Algal Community in different Ponds in Coal Mining City Dhanbad, Jharkhand, India

Suman Dhar, Kumar Nikhil

Ten ponds in coal mining city Dhanbad were selected for this study to calculate the Species richness, Species evenness and Sannon diversity index for algae in summer season and a total of 36 species were recorded. To elucidate the community structure in each pond, these indexes were calculated. The Species richness, Species evenness and Sannon diversity index indicates the pollution index of different ponds in coal mining city Dhanbad affected by different sources. In ten ponds the indices do not go hand in hand indicating higher diversity with moderately to higher pollution level. Algal biodiversity indices can be used in detecting the community structure and level of pollution in these ten ponds.
