to abiotic factors of Nainital lake of Kumaon Himalayas of Uttarakhand State,
India. The samples were collected from the three selected study sites for the
period from May, 2007 to April, 2009. A total of 25 genera of phytoplankton
were reported belonging to 3 groups viz., bacillariophyceae (13 species), chlorophyceae
(8 genera) and cyanophyceae with 4 genera. Members of bacillariophyceae and
chlorophyceae were found to dominant during winter and monsoon months at all
the sites. Site II has the maximum number of phytoplankton followed by Site
III and Site I. Bacillariophyceae were positively correlated with GPP, chlorophyceae
and with zooplankton while negatively correlated with alkalinity and dissolved
solids and with chlorides at all the sites. Chlorophyceae was found to be positively
correlated with hardness, GPP, bacillariophyceae and zooplankton while chlorophyceae
was negatively correlated with alkalinity, total dissolved solids and chlorides.
Cyanophyceae was positively correlated with GPP, NPP while negatively correlated
with free CO2 and total dissolved solids. Maximum species richness
was recorded as 0.458 for cyanophyceae at Site-I followed by bacillariophyceae
(0.366) and minimum was observed in chlorophyceae (0.182) at Site-III. As far
as species diversity is concerned, maximum diversity was observed in bacillariophyceae
(2.329) and minimum in cyanophyceae (1.335). Abundance percentage was recorded
maximum (56.91%) in chlorophyceae at Site-III and minimum as 2.52% in case of
cyanophyceae.]]>Al-Hassan, F.I.,20012001Al-Tayyar, T.A., A.S. Shihab and M.A.A. Al-Allaf,200811125135APHA.,199820th Edn.,Ariyadej, C., R. Tansakul, P. Tansakul and S.
