Preliminary Report on Diatom Species of Brahmsarovar in District Kurukshetra, Haryana (India)

摘要

Study has been conducted in diatomology division offorensic science laboratory, Madhuban, Karnal (29° 40′ 48″ N to76° 58′ 48″ E), Haryana (27° 39′ and 30° 55′ N latitude, 74° 27′and 77° 36′ E longitude), India. During fortnightly periodic visits(from November, 2011 to April, 2012) water samples werecollected from study site (Brahmsarovar in district Kurukshetra,Haryana, India) and carried out in forensic science laboratory,Madhuban, Karnal (H). Water samples were centrifuged andidentified with standard methodology (Venkataraman, 1939;Gandhi, 1956 and 1999; Smith, 1950; Digincamillus et. al., 2011).In our present study, ten numbers of diatom species namely,Cymbella tumida, Melosira granulata, Cyclotella striata,Stephanodiscus sp., Tabelaria sp., Synedra ulna, Diploneissubovalis, Pennium sp., Gomphonema striata and Rhopalodiagibba were observed. Equability index or species evenness (J)may varied from minimum 0.9613 (December, 2011) to maximum0.9937 (February, 2012) with an average± S.E., 0.9802±0.0130;Shannon-Wiener index (H) of studied species may varied fromminimum 2.930 (January, 2012) to maximum 3.193 (December,2011) with an average± S.E., 2.988±0.172 and Simpson-Index (SI)of studied species may varied from minimum 0.0994 (February,2012) to maximum 0.1354 (April, 2012) with an average± S.E.,0.1155±0.131.
