Bacillariophyceae as Ecological Indicators of Water Quality in Two Lakes of Mysore
Journal Title: Universal Journal of Environmental Research and Technology - Year 2014, Vol 4, Issue 1
Abstract
The insights for Biomonitoring and ecological assessments, focusing mainly on the diatom communities in two lakes of Mysore have been explored in this paper. The OMNIDIA GB 5.3 software has been used to derive the Louis Laclercq IDSE/5 index. The findings from the study show that the diversity of Bacillariophyceae was found to be considerably high in Karanji Lake when compared to Kukkarahalli Lake. Organic pollution was not detected in both the lakes while the level of anthropogenic pollution was ‘low’ to ‘moderate’ in both the lakes. On the other hand, level of degradation remained ‘low’ always in Karanji Lake while it was ‘low’ to ‘moderate’ in Kukkarahalli Lake. Synedra ulna was the most common species indicating the anthropogenic pollution. The ecological indicator values represent deteriorating water quality in both the lakes, the main reason being human interferences causing a direct impact on the lake ecosystems. Biomonitoring has been proven to be necessary supplementary to the traditional monitoring techniques and hence the importance of Bacillariophyceae as ecological indicators of water quality has been stressed.
