A species of Pseudo-nitzschia isolated from Sevastopol Bay, Black Sea, was examined for its toxicity. The species was identified as P. calliantha Lundholm, Moestrup et Hasle based on SEM and TEM examination. Domoic acid (DA) was detected in batch culture throughout the growth cycle of P. calliantha. The production of DA by this diatom species was confirmed by fluorenylmethoxycarbonyl (FMOC) derivatization and HPLC-fluorescence method. The cellular DA level was higher in the early exponential phase, with the maximum value of 0.95 pg DA cell(-1). In the stationary phase, the cellular DA levels declined. This is the first record of a DA producing diatom isolated from the Black Sea.

Polycyclic aromatic hydrocarbons (PAHs) in sea sediments of the Turkish Mediterranean coast, composition and sources
Tuncel, Süleyman Gürdal (2015-03-01)
The concentrations of polycyclic aromatic hydrocarbons (PAHs) were determined in 25 surface sediment samples from five sites located at Oludeniz Lagoon of the Turkish Mediterranean coast. The total concentration of the PAHs (1.85 +/- 1.39 mg/kg) was lower than the sediments from highly urbanized areas, while it was comparable with the sediments from similar locations. Acenaphthene and chrysene were dominant ones with the concentrations of 0.620 and 0.515 mg/kg, respectively. The isomeric ratios indicated th...
Vertical distribution of marine cyanobacteria Synechococcus spp. in the Black, Marmara, Aegean, and eastern Mediterranean seas
Uysal, Zahit (2006-01-01)
The vertical distributions of the unicellular cyanobacteria Synechococcus were studied in several highly contrasting seas: the Black Sea, Sea of Marmara, Aegean Sea, and Mediterranean Sea. Cell abundances varied significantly on both vertical and horizontal scales in all physically and spatially discrete water masses. Epifluorescence microscope cell counts from all seas clearly showed that majority of the population remains suspended in the surface-mixed layer and decreases gradually towards the base of the...
Diurnal gut pigment rhythm and metabolic rate of Calanus euxinus in the Black Sea
Besiktepe, S; Svetlichny, L; Yuneva, T; Romanova, Z; Shulman, G (Springer Science and Business Media LLC, 2005-04-01)
The vertical distribution, diel gut pigment content and oxygen consumption of Calanus euxinus were studied in April and September 1995 in the Black Sea. Gut pigment content of C. euxinus females was associated with diel vertical migration of the individuals, and it varied with depth and time. Highest gut pigment content was observed during the nighttime, when females were in the chlorophyll a (chl a) rich surface waters, but significant feeding also occurred in the deep layer. Gut pigment content throughout...
Atmospheric deposition of inorganic phosphorus in the Levantine Basin, eastern Mediterranean: Spatial and temporal variability and its role in seawater productivity
Markaki, Z; Oikonomou, K; Koçak, Mustafa; Kouvarakis, G; Chaniotaki, A; Kubilay, N; Mihalopoulos, N (2003-07-01)
Total and dissolved inorganic phosphorus (IP) was measured in both rainwater and aerosol samples collected from two remote coastal areas: on the island of Crete (Greece) and at Erdemli (Turkey). Particle size distributions of P, as well as total deposition were also measured. Wet and dry deposition of dissolved inorganic phosphorus (DIP) from Crete are compared with simultaneously obtained dissolved inorganic nitrogen (DIN) and with productivity data from the literature. Our results indicate that (1) in bot...
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...
