“…Zooplankton abundance measured in the study area was consistent with findings reported in Trieste Bay (Mozetic et al, 1998) and the Neretva Canal (Vidjak et al, 2007) in the Mediterranean Sea. However, zooplankton abundance in the present study was found to be higher than in certain coastal areas such as Maliakos Bay (Christou et al, 1995), the Balearic Sea (Fernandez de Puelles et al, 1998), Gökçeada coastal waters in the North Aegean Sea (Tarkan, 2000), the North Adriatic Sea (Guglielmo et al, 2002), Lebanese coasts (Lakkis, 2007), and Naples Bay (Ribera d ' Alcala et al, 2004;Mazzocchi et al, 2011). Additionally, compared to areas such as Blanes Bay (Calbet et al, 2001) and the Vranjak Basin (Vidjak et al, 2006), zooplankton abundance was found to be lower in the present study.…”

IntroductionThe coastal marine environment has great ecological and economic importance. It is highly sensitive and variable because of the variations in terrestrial input and open seawaters. In particular, estuaries and bays support various communities and are directly or indirectly affected by human activities (Cummins et al., 2004) and physical, chemical, and biological processes. Zooplanktonic organisms are one of the most important components of aquatic ecosystems; they convert plant protein into animal protein and contribute to matter and energy cycles. In addition to their important role in the food chain, these organisms are rapidly affected by variations in environmental factors and therefore provide information about the status of the ecosystem. Zooplankton composition in coastal areas can vary under specific hydrographic conditions, and these organisms reflect sharp changes in environmental factors such as temperature, salinity, light, density, and water circulation (Sherman, 1967).İskenderun Bay is located on the southeastern coast of Turkey. The bay is surrounded by many industrial facilities, and agricultural activities are carried out in the areas adjacent to the bay (Aksu et al., 2013). Approximately 500,000 people live around the bay, and, as the bay is a touristic spot, this number increases during summer. Moreover, fishery activities are intensively carried out in the bay. It has been observed that the bay is influenced by human activities (Terbiyik Kurt and Polat, 2013).The aim of this study was to increase our knowledge about the seasonal distribution of zooplankton abundance, group, and size composition and the impact of certain environmental parameters on zooplankton distribution in İskenderun Bay. This study will contribute to a better understanding of the coastal zooplankton ecology and provide basic information for long-term future studies in İskenderun Bay.There have been several studies on the distribution of zooplankton groups, abundance, and biomass in the coastal waters of the western

“…Along the considered transect (about 900 m 2 ), the population of E. racemosum consumes from 37 to 800,000 mg C per month (Table 6) and a total of 1,200 g C per year. It is intriguing that most of the preys of E. racemosum from the North Adriatic Sea are benthic or meroplancktonic organisms (benthic foraminifers, nematodes, larvae of bivalves, ascidians and embryos of harpacticoid copepods), while calanoid copepods and cladocerans, the main components of the plankton of the North Adriatic sector (Guglielmo et al, 2002), were very scarcely recorded.…”

Benthic suspension feeders in shallow waters develop in relation to the food availability and the variation of physical parameters giving rise to complex communities that act as a control factor on the plankton biomass. The aim of the work is to establish the role of the hydrozoan Eudendrium racemosum in the energy transfer from the plankton to the benthos in marine food chains of the North Adriatic Sea. This study highlighted that the hydroid biomass changed over time in relation to temperature and irradiance, and the highest abundance was observed during summer with about 400,000 polyps m -2 (about 19 g C m -2 ). The population suffered an evident summer decrease in relation to a peak of abundance of its predator, the nudibranch Cratena peregrina, whose adult specimens were able to eat up to 500 polyps day -1 and reached an abundance of 10 individuals m -2 . The gut content analysis revealed that the hydroid diet was based on larvae of other benthic animals, especially bivalves and that the amount of ingested preys changed during the year with a peak in summer when it was estimated an average predation rate of 13.7 mg C m -2 day -1 . In July, bivalves represented over 60 % of the captured items and about 18 mg C m -2 day -1 . Values of biomass of E. racemosum are the highest ever recorded in the Mediterranean Sea, probably supported by the eutrophic conditions of the North Adriatic Sea. Moreover, our data suggest that settling bivalves provide the greater part of the energetic demand of E. racemosum.

“…This fairly stable pattern of occurrence and relative abundances of these six most successful species were repeatedly observed during our 5-years of observations. Earlier investigations of copepods in the NA (Guglielmo et al, 2002) (Turner, 1984;Suzuki et al, 1999;Calbet et al, 2007;Renz et al, 2008;Gentsch et al, 2009). It is therefore obvious that during the course of the year, vertical separation and probably some food resource partitioning contribute to the concurrent presence of these six species in our investigated area.…”

“…Among the Adriatic subbasins, the northern Adriatic (further NA) is generally considered as the most productive part, where zooplankton is fuelled by the high concentration of living and non-living particulate organic matter in addition to a high phytoplankton biomass sustained by the availability of nutrients (Guglielmo et al, 2002;Fonda Umani et al, 2005). The influence of the longitudinal north-south gradient on zooplankton communities in the Adriatic Sea is well documented; it has been shown that biomasses of all plankton groups show a strong decrease from the NA southwards, whereas a reverse gradient is evident for plankton diversity (Hure et al, 1980;Fonda Umani, 1996;Hure and Kršinić, 1998).…”
