Identification of algae as pollution bioindicators in the Shakh-Kenar, Gavkhouni Wetland, Isfahan

Identification of algae of Shakh-Kenar, Gavkhouni Wetland, was studied from September 2017 to November 2018 at three stations with three replicate. A total, 69 species and 43 genera belonging to six divisions were identified. Species were belonging to the Bacillariophyta, Chlorophyta, Cyanophyta, Euglenophyta, Dinophyta and Chrysophyta. The density variations of the algae were between 98 and 1597 Cells/Cm3. The highest density was found at station 1 in the autumn. According to the Shannon-Weaver Index, the highest and the lowest diversity was observed in autumn and winter, respectively. Bacillariophyta, especially pennate forms; such as Navicula, Nitzschia, Cymbella, and Ulnaria were semi dominant in the most stations. From Chlorophyta; Pediastrum, Cladophora and Scenedesmus were showed conspicuous increase in summer and early autumn. Chroococcus disperses (Keissl.) Lemn, Merismopedia punctata Meyen, Oscillatoria sp. were demonstrated more abundance in autumn. Phacus sp., Euglena caudata Hubner, Trachelomonas playfair Defl., Glenodinium quadridense (Stein.) Schiller, Ceratium hirundinella (O. F. Muell.) Duj and Peridinium cinctum Muell., were observed in later summer and autumn. Regarding to taxa list, kind of pollution index algae and water quality index were recognized from Chlorophyta, Cyanophyta, Dinophyta and Euglenophyta, that they have an important role in changing of water odor/taste, blocking and corrosion of tubes and methods, and production of toxins.
