We tested how functional diversity (FD) along with its three components are correlated to ecological traits of nonmarine ostracods at seven elevational ranges from 800 to 1500 m. 38 ostracod taxa were collected from 55 aquatic sites in Aksaray province (Turkey). 21 species were new reports for the province. Shannon-Wiener diversity index indicated four cosmopolitans with more than 90 % of contribution. Results of the Canonical Correspondence Analysis (CCA) explained 76.8 % of the correlation between species and environmental variables. Salinity was the most effective variable on species. The highest functional divergence and functional richness were found in the elevational ranges of 800 – 899 m and 1100 –1199 m, respectively. When the highest functional evenness was accounted for the 1400 –1499 m, the functional dispersion was found higher in the range of 1200 –1299 m. A medium length of the carapace, the left valve overlaps the right valve, long swimming setae on the second antenna, a welldeveloped uropod, and a smooth carapace surface are the common traits of the species used in FD. Sampling sites were clustered by the common species, which also showed correlation with four cations (Ca, Na, Mg, K). Results suggest that ‘functional diversity’ can be used to correlate ostracod traits with their functional ecology.
