Özet

In order to compare the ostracod species composition of the Zonguldak and Bartin regions of Turkey, samples were collected from 105 aquatic sites with 7 different habitats during June 2013. Thirteen and 18 species were identified from Bartin and Zonguldak, respectively. While all of the species are new reports for Bartin, 11 species are new for Zonguldak. Twenty-two species were common in both regions, with 40.9% similarities. Species abundance (49.2 individuals/site) was found to be greater in Zonguldak than in Bartin (33 individuals/site), but the number of species per sampling site was higher in Baron (0.48 spp./site) than in Zonguldak (0.42 spp./site). Increasing the numbers of sampling sites did not increase the numbers of species. Among the habitat types, the numbers of species per site was the lowest in troughs (0.35 spp./site). Canonical correspondence analyses explained 78.3% of the correlation with relatively low variance (9.8%) between the 15 most common species and 4 environmental variables in the regions, where water temperature (F = 3.216; P = 0.002) and electrical conductivity (F = 2.525; P = 0.018) displayed strong correlation with the species. However, water temperature per se did not show a significant effect on the numbers of species (P > 0.05). Cosmopolitan species showed relatively high tolerance and optimum values to different environmental variables.
