“…This may be explained by the aggregation of N. scintillans during the period of mass development in the cold layers of the Black Sea, which do not flow into the Bosphorus Strait (Bityukov 1969). In the Marmara Sea, the population of N. scintillans occupies the thin surface layer formed by the Black Sea water (Isinibilir et al 2011) due to the fact that body density of this dinoflagellate is close to the Black Sea water density (Bityukov 1969). During 2005-2009, the maximum abundance of N. scintillans reached 550,000 ind.…”

“…In the Bosphorus Strait, the copepod A. clausi basically contributes to necrozooplankton. Isinibilir et al (2011) ). According to our refined estimation, the biomass of dead A. clausi during the same studied period amounted to 92.5 mg m −2 .…”

“…In the sea, four main groups of mesozooplankton (Copepoda, Cladocera, Sagitta, Oikopleura) and a dinoflagellate Noctiluca scintillans (Macartney) Kofoid et Swezy, 1921 are of Black Sea origin and inhabit predominantly the upper lаyers with a salinity of 18-22‰, while the Mediterranean Sea species (mostly copepods) occupy the deep layers of 38-39‰ (Yuksek et al 2003;Tarkan et al 2005;Isinibilir et al 2011).…”

“…According to Isinibilir et al (2011), copepods constitute 79-93% of mesozooplankton in this region, with Acartia clausi Giesbrecht, 1889 being the most abundant species (Benli et al 2001). Previously, Svetlichny et al (2006) and Hubareva et al (2008) showed that individuals of A. clausi which are sensitive to high salinity and transferred from the Black Sea to the Marmara Sea through the Bosphorus Strait did not survive in the salinity gradient layers and, as a result, deepwater zooplankton of the southern Bosphorus mainly consisted of dead organisms of Black Sea origin.…”

“…Oğuz and Öztürk (2011) also reported the important role of the salinity gradient in the Bosphorus Strait area as a barrier to species exchange between the two seas. High mortality of copepods in the Marmara Sea near the Bosphorus area (calculated to be 0.69 d −1 , see Isinibilir et al 2011) can significantly contribute to the concentration of organic matter in this region. Morever, in the highly polluted areas of the Marmara Sea, the heterotrophic dinoflagellate N. scintillans can develop successfully (Koval 1984;Yılmaz et al 2005;Zaika 2005;Pavlova & Melnikova 2006), consuming A. clausi eggs (Daan 1987;Quevedo et al 1999).…”

The dynamics of abundance and biomass of Noctiluca scintillans (Dinoflagellata) and Acartia clausi (Copepoda) in the Bosphorus area of the Black and Marmara Seas during 2005-2009 has been analyzed. Despite the fact that the more abundant Black Sea zooplankton community permanently enters the Marmara Sea, A. clausi and N. scintillans have formed independent populations in the northeast of the Marmara Sea. This may be confirmed on the one hand by the positive correlations between the numbers of A. clausi and N. scintillans individuals in the Marmara Sea near the Bosphorus Strait and near the Prince Islands and, on the other hand, by a lack of correlation between the abundance of these species in the Marmara Sea and in the Bosphorus area of the Black Sea. The abundance of N. scintillans was 6-10 times lower in the Black Sea near the Bosphorus Strait than that in the Marmara Sea. A high correlation (r = 0.84) between the abundance of N. scintillans and the number of dead A. clausi females near the Bosphorus Strait in the Marmara Sea suggests an important role of necrozooplankton in the development of the dinoflagellate.

Dead copepods (carcasses) are widespread in aquatic systems, but their scientific quantification is rare due to the difficulty in discriminating them from live ones. In this paper, we hypothesized that due to large spatial and temporal changes in hydrography in the Cochin backwaters, the percentage of copepod carcasses in the system could also change significantly on a spatial and temporal scale. In order to understand this aspect, we quantified the live and dead copepods in the Cochin backwaters under different hydrographical settings based on live and mortal staining technique. The most prominent temporal hydrographical feature during the study period was the large decline in salinity across the system, which was more pronounced downstream (15-20 units) and was caused by the large freshwater influx associated with the southwest monsoon. During the entire sampling period, copepod carcasses were pervasive all over the study area with large spatial and temporal variations in their percentage contribution (2.5-35.8 %) to the total community abundance. During all sampling, carcasses concentrated more in the downstream region, with maximum turbidity (16.5-35.8 %), than in the upstream region (2.5-14.5 %). The percentage of carcasses was the highest during the onset of the southwest monsoon (av. 23.64 ± 8.09 %), followed by the pre-southwest monsoon (av. 13.59 ± 6.72 %) and southwest monsoon (av. 8.75 ± 4.14 %). During the onset of the southwest monsoon, copepod carcasses in the downstream were contributed by ∼80 % high saline and ∼15 % low saline species, indicating a salinity shock-induced mortality. On the other hand, the cumulative effect of the long residence time of the Cochin backwaters and high partial predation rate of carnivores contributed to the high abundance of carcasses during the pre-monsoon.
