Lake Management: A Case Study | Chapter 9 | Geography, Earth Science and Environment: Research Highlights Vol. 3

Nowadays, the preoccupation with the environment is increasing. This awareness is a realistic and pragmatic choice owing to the numerous negative impacts of non-environmental-friendly technologies. Eutrophication is one of the major threats to aquatic ecosystems such as lakes. In terms, it may lead to the complete degradation of water quality as well as its environment. As the lake is deeply involved in many ecosystem services, the restoration of eutrophic lakes is very important. The analysis of the water quality of Efoulan Lake shows that Dissolved Oxygen (DO), Nitrate, CO₂ and orthophosphate were 0.08 mg/L, 34 mg/L, 40.5 mg/L and 40 mg/L respectively. This confirms the dystrophic character of the lake. The restoration solutions include dry dredging, sanitation of the River NTSOMO (the lake's tributary), and political measures to encourage the adoption of decentralized green systems.

Impact of Limno-Chemical Features on Distribution and Dynamics of Euglenophyceae in Wetlands of Tumkur, India | Chapter 12 | Recent Research Advances in Biology Vol. 1

 

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.
