Malatya (Türkiye) ilindeki ostrakoda türleri üzerinde ekolojik faktörlerin belirlenmesi

This study aimed to understand ecological effective on non-marine ostracod species in Malatya. Present study includes of 125 different water bodies randomly sampled from Malatya during 3-10 August 2015. Total of 25 living non-marine species (Candona neglecta, Cyclocypris ovum, Cypria ophtalmica, Cypridopsis vidua, C. lusatica, Herpetocypris brevicaudata, H. intermedia, Heterocypris incongruens, H. rotundata, H. salina, Ilyocypris bradyi, I. brehmi, I. gibba, I. inermis, Isocypris beauchampi, Limnocythere inopinata, Potamocypris fulva, P. unicaudata, P. variegata, P. villosa, Prionocypris zenkeri, Pseudocandona albicans, Psychrodromus fontinalis, P. olivaceus, Trajancypris clavata) were recorded and 24 of them were the new report for province. The most common species was I. bradyi and it collected from 24 sampling sites from all type of habitats. C. lusatica was found the first time in Turkey. Canonical corresponded Analyses (CCA) was applied to see correlation between species and ecological variables. The first two axes of CCA explained 66.1% relationship and most effective variables were salinity, water temperature and chloride on ostracods. C2 statistical analyses was applied to determine 15 species' (with 3 or more occurrences) tolerance/optimum value for 20 variables. UPGMA analyses showed 5 clustering group within 15 species. According to the results, ostracod species with relatively wide geographical ranges tend to show wide ecological tolerance ranges corresponding to a reduction to their optimum estimates.
