Alteration of macroinvertebrate community in tropical lentic systems in context of Sediment redox potential and organic pollution

Abstract

Limnological studies in two tropical Indian aquatic habitats showed that macroinvertebrate communities have greater diversity than other biotic communities present there. Sediment redox potential is found to be an important factor for alteration of macroinvertebrate communities in aquatic bodies. Anthropogenic activities have influenced the changing of sediment redox potential values of the studied sites and thereby affected the macroinvertebrate communities. A positive correlation has been established between rH and Margelef index in our study.
