Abstract:

In this study the materials collected from the Northern coasts of Sea of Marmara between 1999- 2000 were evaluated and 33 species from 16 genera has been determined. Among these species Callistocythere diffusa, Loxoconcha littoralis and Loxoconcha pontica are new records for the Sea of Marmara. According to the Spermann analysis the primary hydrographical variables did not seem to be very effective in the distribution dynamics of the ostracod species in the Sea of Marmara. However according to the MDS analysis, it has been observed that Cyprideis torosa was affected by temperature, Xesteloberis communis by salinity, Loxoconcha rhomboidea and Paracytheridea parallia by dissolved oxygen when compared to other species.
