Abstract :A total of 41 freshwater ostracod species belonging to 21 genera was collected from 144 different aquatic bodies in the Bolu region during the summer of 2006. The genus Schellencandona and 12 species insert ignore into journalissuearticles values(Candona weltneri, C. sanociensis, C. lactea, Fabaeformiscandona cf. breuili, F. balatonica, F. brevicornis, F. protzi, F. latens, Schellencandona cf. belgica, Pseudocandona cf. semicognita, Potamocypris similis, and P. smaragdina); are new for the Turkish Ostracoda fauna. Additionally, 5 other species insert ignore into journalissuearticles values(Herpetocypris brevicaudata, Heterocypris salina, H. rotundata, Cyclocypris laevis, Trajancypris serrata); are new for Bolu. UPGMA analyses showed districts of Bolu in 5 clustering groups. The highest habitat similarity insert ignore into journalissuearticles values(75%); was found between Yeniçağa and Göynük, while the least insert ignore into journalissuearticles values(20%); was observed between Seben and Merkez districts. Shannon-Weaver diversity suggested the highest evenness for ostracods at Dörtdivan insert ignore into journalissuearticles values(0.95); and the highest diversity index insert ignore into journalissuearticles values(H`); at Merkez district insert ignore into journalissuearticles values(2.63);. Mechanisms of species dispersion are numerous, and may account for observed distributional patterns.
