Özet:

 

The goal of this study was to determine the monthly variations of phytoplankton composition in the least studied  southern shores of the Black Sea with respect to environmental factors. This region is known to be one of the most eutrophic  seas in the world. During the course of this research, carried out between October 2002 and September 2003, various samples  were collected monthly from a depth of 0.50 m at five stations. A total of 129 taxa belonging to 5 divisions and 14 potentially  HAB species was recorded during this research. Three peaks were observed in the total phytoplankton in October 2002, May  and July 2003. These findings were also supported by chlorophyll a (chl a) concentrations and the biodiversity index of  Shannon-Wiener (H'). TRIX indices were computed in order to identify the trophic level of the region and the research area  was determined to be highly eutrophic. Three groups of samples were described by Hierarchical agglomerative clustering and  Multi-Dimensional Scaling (MDS) ordination. Species displaying a major role in discriminating the groups were  Dactyliosolen fragilissimus (Bergon) G.R. Hassle, 1997, Nitzschia longissima (Brébisson) Ralfs in Pritchard, 1861, Proboscia  alata (Brightwell) Sundström, 1986, Pseudonitzchia pungens (Grunow ex P.T. Cleve, 1897) Hasle, 1993 and Skeletonema  costatum (Greville) P.T. Cleve, 1878 from diatoms, Prorocentrum micans Ehrenberg, 1833 from dinoflagellates and Eutreptia  lanowii Steur 1904 from euglenoids. 	 	 		 .
