Amphipods of the genus Gammarus are a vital component of macrozoobenthic communities in European inland and coastal, marine and brackish waters of the Mediterranean and the Black Sea. Exceptional levels of cryptic diversity have been revealed for several widespread freshwater Gammarus species in Europe. No comprehensive assessment has yet been made...

Background: Amphipods of the genus Gammarus are a salient component of communities in European inland and coastal, marine, and brackish waters of the North Atlantic, the Mediterranean, and the Black Sea. Exceptional levels of cryptic diversity have been revealed for several widespread freshwater species of Gammarus in Europe. No comprehensive asses...

The aim of this tudy is to ascertain the species diversity and density of macrozoobenthic organisms inhabiting the coasts of the Sea of Marmara. To this end, benthic samples were collected using Van Veen Grab at 20 stations (4-199 m) along the coasts of the Sea of Marmara in 2016. Examination of the macrozoobenthic material revealed 13 major taxono...

The purpose of the current study is to evaluate the levels of seven heavy metals (arsenic, copper, zinc, mercury, lead, cadmium and iron) and metal (aluminium,) in the edible tissues of Scophthalmus maximus, Spicara maena, Chelidonichthys lucerna, Alosa fallax and Scorpaena porcus caught in Sinop coasts of the Black Sea. The samples were obtained d...

Most of the univariate indexes used for pollution studies commonly evaluate macrobenthic communities. However, meiofauna can be used since they easily respond to environmental disturbances resulting from both natural and anthropogenic events. Nematode/Copepod index was suggested by Rafaelli and Manson (1981) to investigate the effect of organic pol...

Introduction: There are consumer and prey functions for zooplankton at each level of the marine food chain. Therefore, they probably constitute the living group most affected by changes in the pelagic ecosystem. The mesozooplankton distribution, composition and abundance values were investigated in İğneada (Western Black Sea, Turkey) in this study,...

Syllidae was the be...

Siphonophorae were collected monthly since 2009 at four stations with different hydrographic characteristics at Bay of Boka Kotorska in Southern Adriatic. Three of these stations were placed in the shallow part of the inner bays near the shellfish farm, and four in the Bay of Kotor, Bay of Risan, Bay of Tivat and Bay of Herceg Novi. The special eco...

Sea of Marmara is a semi-closed inland sea with a limited water exchange. Since the definition of “inland sea” does not precisely fit to the this water body, it is more accurate to consider it as an expansion on the Turkish Straits System, supplying the connection between the Black Sea and the Mediterranean Sea. Its hydrographic structure also reve...

Meiofauna as an Environmental Bio-Indicator in Marine Ecosystems

in the present study benthic macroorganism surveys were carried out during Mayand November in 2013, along the Sinop coasts of the Black Sea. Grab is usually employed to sample the communities inhabiting the soft bottoms outside an artificial reef and between the structures constituting the reef.Grab samplers have a known volume and can be appropria...

Sinop considered the mid-point of the Black Sea in Turkey and is located on Boztepe peninsula which is the most extended point of Turkish Black Sea coastline towards north. The fact that three sides of the peninsula are surrounded by sea has made fisheries a significant means of income. Fishery has an important place in the economy of Sinop. The pu...

Metazooan meiofauna are defined by their body size (44-1000 µm) and are the most diversified element of the marine biota: as many as 24 of the 35 animal phyla have meiobenthic representatives which live in meiofauna, whether for all their life or just temporarily. It is the most abundant benthic group in the marine realm, the function of meiofauna...

We investigated DNA barcode sequence variation among 4 dominant species (G. aequicauda, G. crinicornis, G. insensibilis, and G. locusta) of the so-called “locustacomplex” of the Mediterranean Sea. Specimens were collected from multiple locations in the Black Sea, Mediterranean Sea and European Atlantic coasts. DNA extraction, amplification and bi-d...

The Black Sea has historically been one of the most biologically productive reg ions in the world. A lthough it has 168 fish species, there are only a few species of co mmercial impo rtance and the supply of fishes is limited, because intensive fishing, industrialisation and urbanisation have caused the most favoured species to decline. Th is revie...

The molecular diversity of Mediterranean and Black Sea Gammarus has been screened in a previous study that suggested the presence of undiagnosed diversity. Here we investigate further DNA barcode sequence variation in this Gammarus complex, adding specimens collected from Spain, Italy, Turkey and Ukraine. Prior to molecular analyses the specimens w...

Several bioassay methods have been developed since the US EPA/COE (United States Environmental Protection Agency/ Army Corps of Engineers) testing protocol was devised, involving a great variety of test species. The amphipods and the polychates started now to be used routinely as standard bioassay organisms for assessing the toxicity of marine sedi...

There is an increasing demand for energy in the world. It is well known that non-renewable energy reserves will be irreversibly used at some point. The effects of climate change and limited fossil energy resources have led to an increasing interest in generating energy such as electricity from renewable energy resources. Wind energy is currently...

This paper concerns records of species that have extended their distribution in the Mediterranean Sea. The finding of the rare brackish angiosperm Althenia filiformis in the island of Cyprus is interesting since its insertion in the Red Data Book of the Flora of Cyprus is suggested. The following species enriched the flora or fauna lists of the rel...
