In October 2005 species composition and abundance of mesozooplankton collected in the Black Sea (near the entrance of the Bosphorus) and in the Marmara Sea (near the exit of the Bosphorus and Prince Islands) were studied taking into account the number of live and dead individuals. Along the Bosphorus, the numbers of the Black Sea originated Copepoda species reduced whilst the abundance of Cladocera and Oikopleura dioica increased towards the Marmara. The Black Sea species constituting 78% of total fodder zooplankton abundance in the Marmara Sea aggregated mainly in the subsurface layers with lower salinity. In the layers deeper than salinity gradient (25-50 m) 57% of the individuals from these taxa were dead being at different stages of decomposition. Respiration rates of copepods also differed among layers of distinct salinity.

Physiological and ecological studies of Calanus euxinus (Hulsemann) from the Black Sea with comments on its life cycle
Arashkevich, E; Svetlichny, L; Gubareva, E; Besiktepe, S; Gücü, Ali Cemal; Kideys, AE (1998-01-01)
Ecological and physiological study of Calanus euxinus population from the Black Sea was carried out during the cruise of RN Bilim in Autumn 1996. The population was divided into two: active individuals, represented by all developmental stages, and diapausing CVs. The active CIV-CVIs underwent daily vertical migrations, while the diapausing CVs stayed at depth all day long. The population seemed to reproduce actively indicated by the large number of eggs and nauplii in the samples as well as the large propor...
Development and lipid storage in Calanus euxinus from the Black and Marmara seas: Variabilities due to habitat conditions
Svetlichny, LS; Kıdeyş, Ahmet Erkan; Hubareva, ES; Besiktepe, S; Isinibilir, M (2006-01-01)
Oil sac volume, gonad size and moulting patterns were investigated in the copepod Calanus euxinus inhabiting deep and shallow zones of the Black Sea and penetrating into the Marmara Sea. In summer the C. euxinus population in deep layers of the Black Sea was dominated by pre-diapause and diapausing postmoult copepodite stage V (CV) with small sexually undifferentiated gonads and mean lipid content of 14.1 +/- 6.0% of body volume. The lipid content of deep-living females was 7.2 +/- 4.2% of body volume. At t...
Fate of the Black Sea Acartia clausi and Acartia tonsa (Copepoda) penetrating into the Marmara Sea through the Bosphorus
Hubareva, Elena; Svetlichny, Leonid; Kıdeyş, Ahmet Erkan; Isinibilir, Melek (2008-01-01)
In October 2005 spatial distribution of live and dead Acartia clausi and Acartia tonsil was studied in the Black and Marmara Seas and near the Marmara Sea inlet of the Bosphorus, in order to understand their fate upon transportation between two seas. The morphometric characteristics in both species from all studied areas, and the decreased abundance of A. clausi and A. tonsa from the Black Sea towards the Marmara Sea indicate that the Marmara Sea Acartia populations are formed by recruitment from the Black ...
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...
Seasonality of zooplankton in the Southern Black Sea and genetics of Calanus Euxinus (Copepoda)
Ünal, Ebru; Kıdeyş, Ahmet; Graduate School of Marine Sciences (2002)
Seasonality and composition of zooplankton was comparatively studied at two stations (inshore and offshore) off Sinop, in southern Black Sea in 1999. Intra-specific genetic differentiation of the copepod Calanus euxinus dwelling in different layers along the water column was also investigated in samples obtained from different regions of the southern Black Sea in September 2000. A total of 64 zooplankton species were identified in the Sinop region in 1999, most of which being meroplankton. Out of these, 17 ...
