Phytoplankton Diversity in Bangalore Lakes, Importance of Climate Change and Nature’s Benefits to People

Abstract

Studies were carried out during the monsoon of 2017 to observe the percentage of phytoplankton in two lakes namely Nirmalagiri Lake & Kengeri Lake in Bangalore. The work gainsimportance due to long incubation period and scanty rains. Present studies Aims to understand the positive implication of Climate Change and Nature’s Benefits to People, and to analysis the distribution of phytoplankton which was influenced after a continuous rain for six months. In these two lakes seven groups of phytoplankton has been observed, which belong to group Chlorophyceae, Euglenophyceae, Bacillariophyceae, Cyanophyceae, Charophyceae, Dynophyceae. Out of which 6 groups were found in Kengeri Lake while 4 groups were found in Nirmalagiri Lake. The percentage of phytoplankton in Nirmalagiri Lake is 63.28% while the percentage of phytoplankton in Kengeri Lake is 36.71%. In case of Nirmalagiri Lake the percentage has been calculated for different groups. The percentage of Chlorophyceaeis 86.12%, while Euglenophyceaeis 0.90%, Bacillariophyceaeis 5.85%, Cyanophyceaeis 7.11% and incase of Kengeri Lake Chlorophyceaeis 76.55%, Euglenophyceaeis 1.24%, Bacillariophyceaeis 7.14%, Cyanophyceaeis 12.57%, Charophyceaeis 2.32%, Dinophyceaeis 0.15%. Chlorophyceaewas the most dominating group in the both lakes. The diversity indices of the phytoplankton were found using “PAST” software.Keywords:Climate Change; Biodiversity;Phytoplankton diversity; Diversity indices; Bangalore Lakes
