عنوان فارسی Algal community structure and water quality assessment in the Sattarkhan and Sahand Dams, East Azerbaijan Province, Northwestern Iran
چکیده فارسی مقاله Types of algae such as diatoms, green algae and blue-green algae are the most important biological indicators for evaluating the water quality of dams. Algae reflect the ecological conditions of aquatic ecosystems, so that some of them choose a polluted environment for growth. Therefore, algae can be used as an indicator of pollution. In this regard, the present study was conducted in order to determine the algal flora of diatoms, green algae and blue-green algae in the two dams of Sattarkhan and Sahand located in East Azarbaijan province, and also to investigate the effect of some physicochemical factors on algal communities. In this study, samples were taken from Sattarkhan dam reservoir in Ahar city and Sahand dam reservoir in Hashtroud city. Sampling was done seasonally in 2022-2023. In general, the number of 55 genera and 115 species were observed in Indo Dam, and the most diverse species related to Ulnaria and Nitzchia from diatoms and Scenedesmus, Pediastrum, from green algae and Oscillatoria genus from cyanobacteria with 2 species were the most diverse. A high biodiversity of diatoms and green algae was observed in autumn, winter and spring, but the biodiversity of blue-green algae was higher in summer. The statistical analysis of this research showed that the EC parameter has the most significant effect on the algal community compared to other parameters.
