A study on phytoplankton as biological sensor for climate change was conducted for five years. Specifically, to determine species composition in water samples using settled volume method for quantitative microscopic analysis, calculate the total population of each species based on abundance, find out significant differences in the calculated phytoplankton abundance, describe the total population as influenced by the identified environmental factors such as surface water temperature, salinity, and pH, and statistically analyse to assess the role of phytoplankton as biosensor for climate change in a local scale. Results of quantitative microscopic analysis showed year-on-year increase in the total abundance. Abundant species indicator includes Navicula sp. and Fragillariopsis sp. Statistical analysis using ANOVA revealed significant differences in the annual total abundance at p ˂ 0.5. Post Hoc Turkey (HSD) beta showed insignificant differences between any treatment mean population hence the phytoplankton population has the same over-all response to the identified environmental matrices. Further statistical results using Pearson coefficient of correlation showed strong positive correlation which means stability of the population with time. Although micro-scale climate change is yet too far to conclude based on the results, thus the response of phytoplankton assemblage manifests biological sensing ability.
