dc.description.abstractTemporal and spatial changes in abundance, prosome length, oil sac volume, molting patterns and morphometric parameters were studied in Calanus euxinus from the Black and Marmara Seas. In the south-western part of the Black Sea and deep shelf zone near Sinop the abundance of C. euxinus was high during the whole studied period (2000-2005), with a maximum 23,400 ind m-2 in March 2004. In the Marmara Sea near the Prince Islands in the deep zone the mean annual abundance of C. euxinus was 47 times lower than in the deep zone of the Black Sea (during 2000-2007). However, this parameter reached a significant magnitude of 12,264 ind m-2 in spring in Izmit Bay. During the warm season, C. euxinus are rare in the Marmara Sea. The high temperature and salinity accelerate development in this species; therefore, preadults and adults possess reduced prosome length and oil sac volume. In the cold period in the Marmara Sea the size and lipid content in late copepodite stages increase, especially in Izmit Bay. Similar size of eggs, prosome length of early copepodite stages in the Black and Marmara Seas indicate that the C. euxinus population in the Marmara Sea originates from the individuals penetrating from the Black Sea through the Bosphorus.

dc.description.sponsorshipThe present study was partly supported by a TUBITAK ( Turkish Scientific Technical Research Council)-NASU ( National Academy of the Ukraine) joint project ( 107Y001) and a NATO Linkage Grant ( EST NUKR CLG 983036); and the Research Found of the Istanbul University (T-1121) and Ondokuz Mayis University ( S. 090) and the Undersecretary of Organization of Planning of State (TAP-S013). We appreciate the cooperation and help of the staff at the R/ V Bilim'' and Knorr'' during the cruises. This study is a cooperating project of the Census of Marine Zooplankton (CMarZ), a field project of the Census of Marine Life.
