Rawat, M S | Sharma, Ramesh C
The present contribution embodies results of a study on the macrozoobenthosfrom the high altitude lentic environment of Deoria Tal of Garhwal Himalaya.Macrozoobenthos of the lake were contributed by the larvae, nymphs andadults of the Diptera, Ephemeroptera, Hemiptera, Coleoptera and Plecoptera.Representatives of Oligochaeta, Hirudinea and Mollusca were also present.Population density of macrozoobenthos fluctuated from 151 to 290 individualsm2, being maximum in December and minimum in February. It was inferredon the basis of present observations that the abundance of lacustrinemacrozoobenthos was regulated by the seasonal appearance and disappearanceof aquatic macrophytes acting as cover for shelter, nature of substratum andlight penetration
