Özet: Total of 10 Mollusca (Gastropoda and Bivalvia) species obtained from 20 different sampling locations in Tunceli were examined to determine relationships between species and their ecological characteristics from July 2015 to June 2016. Canonical Correspondence Analysis (CCA) was applied to determine the relationships among the Mollusca fauna and physicochemical variables. CCA explained 81.897 % of the species and environmental variation by the second axis. Water temperature (T ), dissolved oxygen (DO ), pH and Ca+2 were the most influential variables on the Mollusca fauna. The influence of electrical conductivity on species distribution was significantly higher (P = 0.02) than that of the other ecological factors. The most frequently occurring species were clustered into 4 main groups based on their ecological characteristics using unweighted pair group mean averages (UPGMA).
