Abstract

– The algal flora and physio-chemical parameters of seven thermal springs in Denizli were studied for the first time. Samples for algal analyses were taken monthly between May 2013 and June 2014, while the physio-chemical parameters were measured seasonally. The mean pH value of the thermal springs was 6.3, and temperatures varied between 34–60 °C. The significant differences (P < 0.001) among the thermal springs were in their temperature and pH, as well as concentration of Cl–, Fe2+, K+, Mg2+, Na+, Li+, Ca2+, HCO3–, and SO4 2– ions. A total of 43 Cyanobacteria and three Bacillariophyta taxa were determined. The most common taxon was Spirulina subsalsa Oersted ex Gomont, sam-pled from five sampling sites. According to the principal component analysis (PCA), the most important determining factor for the algae was temperature, followed by concentration of K+ and Cl– ions.
