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 by the increase in salinity of upper layers (r = 0.30 and r = 0.31, p < 0.001, respectively), while chlorophyll a was negatively affected (r = -0.36, p < 0.001). Even though Noctiluca scintillans had a significant seasonality (F(11.120) = 8.45, p < 0.001, ANOVA), abundance was not related to fluctuations in temperature and only chlorophyll a was adversely correlated (r = -0.35, p < 0.001). In general, there are some minor differences in zooplankton assemblages of upper and lower layers. A comparison of the species composition and abundance of Izmit Bay with other Black Sea bays reveals a high similarity between them.

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...
Annual variations in biochemical composition of size fractionated particulate matter and zooplankton abundance and biomass in Mersin Bay, NE Mediterranean Sea Zenginer Yılmaz, Arife (2010-05-01) Seasonal changes in biochemical composition of different particle size classes (pico-, nano- and micro-particulate matter) and the zooplankton abundance and biomass were studied in NE Mediterranean between November 2004 and January 2006. Sampling was carried out at monthly intervals from two stations representing coastal and open water characteristics. Dominance of size fractions showed seasonal variations in each biochemical component but on annual average pico size fraction predominated and accounted for ...
Weekly Variations in Phytoplankton Structure of a Harbour in Mersin Bay north eastern Mediterranean Eker Develi, Elif; Kıdeyş, Ahmet Erkan (2000-01-01) Weekly variations in the phytoplankton composition of a harbour in Mersin Bay were studied with two methods: filtration for the assessment of >55 μm phytoplankton from July 1995 to June 1997; and sedimentation for the assessment of all phytoplankton (both>55 μm and <55 μm) between 15 February and 25 May in 1996. With both sampling methods, a total of 175 phytoplankton species were identified. In the filtered samples, the total diatom abundance was much higher than that of dinoflagellates. The highest diatom...
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...
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...
