Abstract The present study concerns seasonal variations,
correlation coefficient and biodiversity indices of phytoplankton during
January to December, 2008 in the Harsool-Savangi
dam, Aurangabad, India. A total of 35 genera were recorded out of which 15
were Chlorophyceae, 7 Bacillariophyceae,
7 Cyanophyceae and 6 Euglenophyceae.
Present study revealed maximum percentage wise compositions of Chlorophyceae at north site 41.91%, Bacillariophyceae
at west site 32.70%, Cyanophyceae at south site
19.50% and Euglenophyceae at west site 11.47%.
Minimum percentage wise compositions Chlorophyceae
at south site 37.80%, Bacillariophyceae at east
site 28.15%, Cyanophyceae at west site 17.47% and Euglenophyceae at north site 10.57%. Margalef?s
index (R1) and Menhinick
index (R2) values (4.12 and 0.56) were
found to be highest at south site and lowest values (3.77 and 0.38) were
found at north site. Simpson?s index (I) values (0.30) were found to be the
highest at north site and lowest values (0.29) were found at south, east, and
west sites. Shannon ? Weiner index (H?) values (1.26) were found to be the
highest at south, east, and west sites and lowest values (1.24) were found at
north site. Maximum species evenness was recorded at south site; minimum at
north site. Maximum population density of Chlorophyceae,
Bacillariophyceae, Cyanophyceae
and Euglenophyceae (1923, 1173, 889 and 541 organisms
l-1) were recorded at north site in
summer and minimum (108, 195, 67 and 24 organisms l-1) were recorded at south site in
monsoon, respectively.
