The most productive lake was Balık lake, while the lowest productive lake is Liman lake in the study area. Secondary strategies were found to be dominant in studied lakes. No species exhibit pure S-strategy in the present study. pH, electrical conductivity, P and NH4 concentrations were found to be significant. However, total of nitrite-N and nitrate-N concentrations were not significant. EC and pH were associated with the species in Liman and Cernek lakes, respectively. However, P and NH4 concentrations were associated with the species in Balık lake according to canonical correspondence analysis. Significant correlations were found among chemical traits and biological diversity. pH was positively correlated with Shannon-Wiener index, while negatively correlated with Simpson and Berger-Parker indexes. No significant correlations were found between water P concentrations and evenness. Our data supported intermediate disturbance hypothesis in the studied lakes.
