The monthly and long-term fluctuations of mesozooplankton abundance, biomass, and taxonomic composition in the Sinop inner harbor (southern Black Sea) between 2005 and 2009 are presented in the present study. In total, 31 mesozooplankton taxa were identified during the study. The recorded average mesozooplankton abundance and biomass were 34,323 ± 7580 ind. m and 1208 ± 460 mg m in 2005, 95,063 ± 31,434 ind m and 1787 ± 604 mg m in 2006, 97,626 ± 12,141 ind m and 1034 ± 20 mg m in 2007, 91,918 ± 10,476 ind m and 775 ± 121 mg m in 2008, and 146,918 ± 19,671 ind m and 1955 ± 437 mg m in 2009, respectively. The highest abundance values of mesozooplankton were encountered in March 2006 (299,110 ind m) with the contribution of Copepoda nauplii (167,000 ind m) particularly. Meanwhile, the mesozooplankton biomass was highest in October 2005 (5852 mg m), due to Parasagitta setosa (3695 mg m). The heterotrophic dinoflagellate Noctiluca scintillans was a major component of plankton samples in the Sinop region, presenting its highest values in April 2005. Mesozooplankton abundance values showed significant differences (except 2007-2009 and 2008-2009) during the 5-year sampling period. Since the middle of 2006, an increase in abundance, biomass, and biodiversity of mesozooplankton has been detected. Many mesozooplanktonic species/groups showed seasonality in the study (especially Cladocera species). This seasonality was determined to be based on temperature changes. Anahtar Kelimeler

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...
Seasonal Changes in the Composition and Abundance ofZooplankton in the Seas of the Mediterranean Basin Kovalev, Av; Mazzocchı, Mg; Toklu Alıçlı, Benin; Skryabın, Va; Kıdeyş, Ahmet Erkan (2003-01-01) Seasonal changes in the composition, abundance and biomass of zooplankton in the seas of the Mediterranean basin (the Mediterranean, Black and Azov seas) have been reviewed using our own data and data from the literature. In the deep-water central regions of the seas, the seasonal cycle of zooplankton abundance is characterised by one maximum occurring in spring or summer. In the coastal regions, two to three peaks (spring, summer and autumn) exist for the zooplankton abundance. The amplitude of seasonal fl...
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...
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...
Annual cycle of zooplankton abundance and species composition in Izmit Bay (the northeastern Marmara Sea) Isinibilir, Melek; Kıdeyş, Ahmet Erkan; TARKAN, AHMET NURİ; Yılmaz, İsmail (2008-07-30) The monthly abundance, biomass and taxonomic composition of zooplankton of Izmit Bay (the northeastern Marmara Sea) were studied from October 2001 to September 2002. Most species within the zooplankton community displayed a clear pattern of succession throughout the year. Generally copepods and cladocerans were the most abundant groups, while the contribution of meroplankton increased at inner-most stations and dominated the zooplankton. Both species number (S) and diversity (if) were positively influenced ...
