Impact of Limno-Chemical Features on Distribution and Dynamics of Euglenophyceae in Wetlands of Tumkur, India
This study deals with the distribution and ecology of euglenoids in relation to physicochemical
characteristics of water in four lakes of Tumkur district. Guluru, Bugudanahalli, Colony and Teeta are
the four lakes selected for the present study during 2015-17 and discussed. Euglenoids function as
indicators of aquatic superiority. A total of ten species under three genera were identified. Guluru lake
harbored 46.66% followed by Colony and Teeta lakes 20% each and Bugudanahalli lake with 13.33%.
Seasonally all the lakes recorded maximum density of euglenoids during summer except in Colony
lake, where they reached their peak during rainy season. Euglenoids showed significant positive
correlation with water temperature (r=0.664: P< 0.05), Sulphate (r=0.757: P<0.05) and Silica (r=0.775:
P<0.05) at 5% level. As the euglenoids serve as pollution indicator organisms, moderate density of
euglenoids in the lakes investigated indicates that, lakes are tending towards biologically eutrophic
