Ecological studies of headwater of warm spring in Kilesephyd, Sar-e-Pol-e-Zohab,
In order to investigation of taxonomic composition and physical and chemical characteristics thermal spring in Kilesephyd, ecological factors of headwater of Warm spring in Kilesephyd, Sar-e-Pol-e-Zohab, Kermanshah province, in Iran was carried out. Chemical and Physical Factors (So4-2, No3-, Cl-, Po4-2, Sio2-2, Mg+2, Ca+2, K+, pH, Conductivity, Turbidity) were measured with biological properties (Species composition, chlorophyll-a, Dry mass, Autotrophic index or AI and Ash free dry mass or AFDM). The headwater temperature of the thermal spring remained almost constant over years and the temperature is lower than the ambient temperature in the summer season (28ºC). High concentration of sulfate and conductivity is characteristic feature of this spring. Water sample and cobbles or pebbles collected from headwater. At the end of sampling study, 6 species of Cyanobacteria belong to 4 genera have been determined. Phormidium formosum and Oscillatoria sp. were abundant.
