Benthic Diversity and its Distribution in a Typical Tropical Ramsar Wetland
The present study was conducted on the Upper lake of Bhopal (Ramsar Wetland) situated in the heart of main City. Certain physico chemical and biological parameters were analyzed. During this study 19 families of Benthos were recorded, representing 9 groups which are as Diptera, Hemiptera, Tricoptera, Coleoptera, Odonata, Ephemeroptera, Hirudinea, Oligochaeta, Mollusca. It has been observed that the nutrient rich sites harbour highest number of families. Fresh water ecosystems that are more prone to nutrient enrichment are found to harbour highest density of species. Nevertheless increase in nutrient level beyond a threshold level may reduce the intolerant species.
