Species composition, community structure and spatial distribution of net phytoplankton in the southern Black Sea have been studied. In the fraction over 55 mum, diatoms were found to be predominant in cell abundance and followed by dinoflagellates. Net phytoplankters were found to be more abundant in the southwestern sector, especially near the Bosporus and near Sakarya River mouth. MDS (Multi-Dimensional Scaling) analysis has projected four distinct patches along the coast, two of which appear to occupy smaller regions compared to the main western and eastern patches which have lower species numbers and diversity. The diatom species Pseudo-nitzschia seriata and Cerataulina pelagica and the dinoflagellates Noctiluca scintillans and Scrippsiella trochoidea dominate the west, while diatom species Synedra acus and Asterionella formosa together with Microspora sp. and Ankistrodesmus falcatus from chlorophyceae dominate the east.

Distribution of phytoplankton in the southern Black Sea in summer 1996, spring and autumn 1998 Eker-Develi, E; Kıdeyş, Ahmet Erkan (2003-03-01) The species composition, abundance, and biomass of micro- (>15 mum) and nano- (<15 mu m) phytoplankton were studied along the southern Black Sea during June-July 1996 and March-April and September 1998. A total of 150 species were identified, similar to 50% of them being dinoflagellates. The average total phytoplankton abundance changed from 77 x 10(3) Cells l(-1) in spring to 110 x 10(3) cells l(-1) in autumn and biomass from 250 mu g l(-1) in summer to 1370 mu g l(-1) in spring. Based on the extensive sam...
The diel vertical distribution of zooplankton in the southeast Black Sea Erkan, F.; Gücü, Ali Cemal; Zagorodnyaya, J. (2000-01-01) The diel changes in the vertical distribution of zooplankton in the southeast Black Sea were described in this study. The zooplankton were sampled using two different sampling methods throughout one day in October 1996 and July 1997 at the same station. The zooplankton counts, the length measurements and biomass estimates showed that the zooplankton in the southeast Black Sea is dominated by small organisms, among which Noctiluca scintillans is the dominant species. In the vertical distribution of zooplankt...
Phytoplankton distribution in the western and eastern Black Sea in spring and autumn 1995 Eker, E; Georgieva, L; Senichkina, L; Kıdeyş, Ahmet Erkan (1999-12-01) Species composition, abundance, and biomass of micro- (>15 mu m) and nano(<15 mu m) phytoplankton were studied in the western and eastern Black Sea during March-April and October 1995. A total of 142 species were identified, of which >50% were dinoflagellates. Abundance and biomass values were lower during the March-April period (average 129 +/- 28 thousand cells I(-1) and 330 +/- 124 mu g I(-1)) than during the October period (average 364 +/- 161 thousand cells I(-1) and 1794 +/- 515 mu g I(-1)) and compar...
Estimation of phytoplankton biomass using HPLC pigment analysis in the southwestern Black Sea Ediger, D.; Soydemir, N.; Kıdeyş, Ahmet Erkan (2006-01-01) The phytoplankton population of the southwestern Black Sea in May 2001 was studied by taxonomic analysis using microscopic examination and by pigment analyses using high-performance liquid chromatography (HPLC). Pigment data, which identified phytoplankton assemblages dominated by dinoflagellates, diatoms and coccolithophores in May 2001, were compared to phytoplankton cell counts and biomass. There were significant (p < 0.002-0.01, r=0.56-0.67) relationships between the taxon-specific pigment concentration...
Zooplankton of the Black Sea and the Eastern Mediterranean Similarities and dissimilarities Kovalev, Av; Mazzocchı, Mg; Sıokoufrangou, I.; Kıdeyş, Ahmet Erkan (2001-01-01) A synthesis of data on abundance and biomass of zooplankton in the Eastern Mediterranean (EMED) and the Black Sea shows major differences in the composition and structure of pelagic communities in the two basins. Few Mediterranean planktonic animals have invaded in the Black Sea. The great bulk of Black Sea species is represented by coastal inhabitants that spread throughout the whole basin. This process has been called “neritization” of the Black Sea fauna. Peculiarities in zooplankton assemblages of the B...
