Impact of Limno-Chemical Features on Distribution and Dynamics of Euglenophyceae in Wetlands of Tumkur, India

September 2, 2020 BIOLOGY 0

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

condition.
