Seasonal and spatial distribution of some benthic Protozoa in an eutrophic freshwater lake of Central Himalaya
The species composition, population density and diversity of benthic Protozoa in the littoral zone of Lake Naini Tal during 1993 -1994 are described both seasonally and spatially. Ciliates were dominant protozoans in terms of abundance. Most common were Branchioecetes sp. Penard, Bursaridium sp. Lauterborn, Paramecium multimicronucleatum Power and Mitchell, P. aurelia Ehrenberg, P. caudatumEhrenberg, Spirostomum minus Raux and S. teres Claparede and Lachmann. Protozoans were the most abundant in winter and summer. Both the peaks were preceded by phytoplanktonic peaks in the lake. Spatially, the maximum concentration of Protozoa was found at a site, influenced by pollution.
