Spatial and temporal changes of plankton assemblages in Atrai River, Bangladesh

Abstract: The present study investigates the changes in plankton assemblages and the causal factors at Atrai River in Bangladesh. Monthly sampling of plankton and water quality parameters were performed. Plankton assemblages were characterized with high dominance of phytoplankton (88%), while zooplankton represented only 12% in the plankton community. A total of 49 genera of plankton and 11 genera of zooplankton were identified. The distance-based linear model (DistLM) detected temperature, pH, water transparency and dissolved oxygen (P=0.001) as key environmental factors predicting the changes in plankton assemblages in the study region. The changes in abundance and distribution of plankton are primarily driven by the variability of temperature and pH following water transparency and dissolved oxygen in the Atrai River. The outcomes of this study improve our understanding of the variability in plankton community and regulating environmental drivers in the river system.
