Studies covered enumeration of individual phytoplankton, zooplankton & meiobenthic organisms; application of Shannon weaver diversity index & similarity index, and evaluation of food web trophic levels & ecological pyramid. Sixteen, 7 and 1 varieties of phytoplankton, zooplankton and meiofauna respectively were recorded in Zub lake. The lake which receives water from nearby glaciers and measures 0.35 sq.km. is the source of water for Maitri. Besides plankton, the lake represented detritus and moss at different trophic levels. Considering producer and first consumers as the two-step trophic structure, ecological pyramid on the basis of biomass has been formulated for Zub lake. Details towards variations of flora and fauna among different water bodies, probable reasons for such variations and ecological efficiency The continuously increasing interest in, and exploitation of, the natural resources of the Antarctic continent and its surrounding waters by a number of nations, requires a comprehensive knowledge of the Antarctic ecosystem if that ecosystem is to be effectively managed and conserved. Few attempts were made to investigate biota at shallow freshwater lakes in Schirmacher Oasis of Antarctica (Komarek and Ruzicka 1966, Kaup 1988, Ingolc and Parulekar 1993). Although species composition and, to a limited extent, ecology of the biota have been determined in a few studies, quantitative data are still inadequate. In general, Antarctic lakes possess relatively short and simple food chain. Kok and Grobbelaar (1978) stated that the zooplankton occupy the top of the food chain due to the absence of fish in Marion islands lakes. They found a significant correlation between average primary production rates measured by Grobbelaar (1974) and zooplankton biomass in various water bodies. completed principalInvestigator National Centre for Polar and Ocean Research (NCPOR) 8322525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND ictd@ncpor.res.in Dr. T K Ghosh climatologyMeteorologyAtmosphere 20.0 140.0 -90.0 30.0 1993-01-01 1994-12-31 Earth Science-Sun-Earth Interactions Theme Schirmacher Oasis Antarctic Place Biotic Features of Selective Surface Water Bodies around Indian Station Maitri in Schirmacher Oasis Project eng TableDigital unknown unknown unknown distributor National Centre for Polar and Ocean Research (NCPOR) +91-832-2525515 voice Headland Sada, Vasco da Gama, Goa 403804 Vasco-da-Gama Goa 403804 IND vssamy@ncpor.res.in Mr. Sakthivel Samy V http://npdc.ncaor.gov.in/npdc/search_mf_data.action?search=freeText&expedition_type=all&parameter=MF325054173&userType=user&freeTextValue=Biotic+Features+of+Selective+Surface+Water+Bodies+around+Indian+Station+Maitri+in+Schirmacher+Oasis%2C+Antarctica.
