Phytoplankton Communities and Physical-Chemical Properties of Ulaş Lake (Ulaş/Sivas)

Abstract

This study was conducted between December 2010 and December 2011 to reveal the phytoplanktonic groups present in Ulaş Lake and to assess the lake’s physical and chemical properties. A total of 115 species belonging to 7 phytoplanktonic groups were identified in the lake (Chlorophyta: 49, Heterokontophyta: 36, Cyanobacteria: 10, Euglenophyta: 8, Cryptista: 7, Charophyta: 3, and Dinoflagellata: 2). The annual average values for physicochemical parameters were as follows: water temperature: 12°C, dissolved oxygen: 7.5 mg O₂/L, electrical conductivity: 3.59 mS/cm, turbidity: 16.5 NTU, suspended solids: 16 mg/L, pH: 8.6, calcium: 786 mg/L, hardness: 207 mg CaCO₃/L, alkalinity: 140 mg CaCO₃/L, sulphate: 101 mg/L, silica: 1.6 mg/L, chemical oxygen demand: 47 mg/L, chloride: 314 mg/L, total phosphate: 55.4 µg/L, total dissolved phosphate: 32.1 µg/L, soluble reactive phosphate: 11.6 µg/L, chlorophyll-a: 11 µg/L, ammonium nitrogen: 35 µg/L, nitrate nitrogen: 47 µg/L, and nitrite nitrogen: 9 µg/L.
