Evaluation of Phytoplankton Diversity and Environmental Implications of Two Lacustrine Wetlands, Located In Midland and Lowland Critical Zones of Kerala, India
Journal Title: Journal of Environmental and Social Sciences - Year 2018, Vol 5, Issue 1
Abstract
Current study was carried out to provide a better understanding on the species richness of phytoplankton community in two Freshwater lakes of Kerala, namely; Sasthamkotta and Vellayani located in the respective midland and lowland critical zones of Kerala, and their relationship with nutrient status. Samplings were conducted seasonally i.e., during pre-monsoon, monsoon and post monsoon seasons. Water samples were collected for nutrients analysis (TN, NO2-, NO3-, TP and PO43-) and phytoplankton counting. The investigations showed a total of forty-two phytoplankton genera, representative of four families were identified. The nutrient concentrations in the two lake ecosystems show higher values throughout the year and the phytoplankton community show species richness. In general, increase in nutrient concentration triggered the increased diversity of phytoplankton community. This was clearly evident from the correlation analysis, there was a significant positive relationship noticed between phytoplankton community with the nutrient concentrations.
