Seasonal change of community structure and abundance of phytoplankton in Roudan River
Abstract
A combination of environmental conditions affects the phytoplankton distribution and composition. This study analysed spatio-seasonal variation of phytoplankton in relationship to environmental variables in Roudan River (Iran) which has a good water quality and thus this research is important as a basis for future sustainable management. Phytoplankton and environmental variables were sampled monthly at 3 stations the upstream , intermediate and downstream zones from April 2013 to April 2014. Differences in the abundance, species diversity and dominant taxa of particular groups of phytoplankton between three sections of river were analyzed. River has a long and shallower depth and is susceptible to have different situation as ecological status. The results of the studies confirm that there are differences in the phytoplankton communities and physiochemical water parameters in the studied river. The abundance of diatoms dominated by Nitzschia and Navicula, noted in winter was almost 120-70 times higher than spring. Most of the sample was taken in autumn and winter and due to high water temperature the abundance was in colder water temperature. Both diatom phytoplankton was in highest frequency in two station, but very few plankton were selected in station one. The significant increasing of salinity (P<0.05) in the autumn and winter season also may provide increasing phytoplankton as well. Concluded that the species number and celldensity of phytoplankton could serve as biological water quality indicators, which would give overalldescriptions of water quality by combining with the physical and chemical indicators.
