Levent; Tuncer, Sezginer; Poursanidis, DimitrisEven if the Mediterranean Sea is considered one of the most studied areas concerning its malacofauna, to date few areas have updated species lists, which are important for ecological and conservation studies. This study deals with the sea slug fauna of the Sea of Marmara, an important region in the Mediterranean Sea area acting as the connection point with the Black Sea. Information reported in the scientific literature as well as material from research projects have been collected and analysed, revealing 52 records of sea slugs and shelled relatives from the Sea of Marmara belonging to 32 families. From the 52 species, 11 are reported for the first time from the region while two of them are considered invasive species.Öğe First Record of Armina neapolitana (Delle Chiaje, 1824) (Gastropoda: Heterobranchia) in the Sea of Marmara (Turkey)(Cahiers De Biologie Marine, 2016) Tuncer, Sezginer; Artuz, M. Levent; Onal, UmurIn August 2015, three specimens of Armina neapolitana were collected from a depth of 64 m in the Sea of Marmara, Turkey. This is the first record of Armina neopolitana, a previously unknown species in Turkish waters.Öğe First record of Callinectes sapidus Rathbun, 1896 (Crustacea: Decapoda: Brachyura) in the Dardanelles, Canakkale, Turkey(Regional Euro-Asian Biological Invasions Centre, 2008) Tuncer, Sezginer; Bilgin, SabriA single mature female specimen of Callinectes sapidus was captured on 14 November 2008 off Canakkale, Turkey. This is the first record of the blue crab from the Dardanelles. © 2008 The Author(s).Öğe First record of straight-needle pteropod Creseis acicula Rang, 1828 bloom in the Canakkale Strait (NE Aegean Sea, Turkey)(De Gruyter Open Ltd, 2021) Tuncer, Sezginer; Öǧretmen, Nazik; Çakır, Fikret; Öztekin, Alkan; Oral, Ayhan; Suner, Salih CanPteropods are marine pelagic calcifier mollusks sensitive to chemical changes in seawater due to their highly soluble aragonite shells. Increased acidity (reduced pH) of seawater causes difficulties in precipitating their shells and/or results in their dissolution, which is related to increased atmospheric CO2 concentrations and warming of seawater. They are therefore indicators of environmental changes. In this paper, we present the first record of the straight-needle pteropod Creseis acicula Rang, 1828 bloom in the surface waters of the Çanakkale Strait, Turkey (NE Aegean Sea), encountered in July 2020, when the highest sea surface temperatures and pH levels since 2007 were recorded. In coastal zones, such as the Çanakkale Strait, anthropogenic activity contributes significantly to environmental changes. Consequently, the increase in pH at elevated temperatures indicates an auxiliary factor (i.e. anthropogenic activity) that triggered the C. acicula bloom, rather than global atmospheric CO2 levels.Öğe First record of the Lessepsian migrant Lagocephalus spadiceus (Tetraodontidae) in the Sea of Marmara(Soc Francaise D Ichtyologie, 2008) Tuncer, Sezginer; Cihangir, Herdem Aslan; Bilecenoglu, Murat[Anstract Not Available]Öğe First report of occurrence, distribution, and composition of microplastics in surface waters of the Sea of Marmara, Turkey(Pergamon-Elsevier Science Ltd, 2018) Tuncer, Sezginer; Artuz, O. Bulent; Demirkol, Mustafa; Artuz, M. LeventPlastic is produced today in large quantities and used for many purposes. At the end of use, a large part of it gets into the environment, often into the sea and there it is fragmented into the smallest fragments, so-called microplastic (MP). MPs pose a serious challenge to the marine environment such as the sources and properties of MP particles, their impact on marine organisms, and the challenges of environmental pollution. This work, carried out in the fourteen sites in the area, is the first reference to the detection of MP distribution at surface waters in the Sea of Marmara, Turkey. As a result of this study, the average level of MP in the surface was determined to be 1.263 item/m(2). The results were higher compared of the most other adjacent regions and show that the Sea of Marmara started to face that problem.Öğe Further range expansion of the blue crab Callinectes sapidus (Rathbun, 1896) (Crustacea: Decapoda: Brachyura) in Turkish waters, Northern Aegean Sea: insight into distribution depth(Cahiers De Biologie Marine, 2016) Daban, Ismail Burak; Cengiz, Ozgur; Tuncer, SezginerA new record of Callinectes sapidus from the northern eastern part of the Aegean Sea is presented, based on a live single female sampled off northern part of the Gokceada (Imbroz) Island. Surprisingly, the individual which is known shelf-estuarine species was sampled at 220 m depth with a bottom trawl on November 15th, 2015.Öğe HEAVY METAL CONCENTRATIONS IN Mytilus galloprovincialis FROM CANAKKALE STRAIT, NW TURKEY(Parlar Scientific Publications (P S P), 2015) Özden, Serkan; Tuncer, SezginerMytilus galloprovincialis, a bioindicator, was collected from the Canakkale Strait to investigate heavy metal concentrations related to contamination. Pb, Cu, Zn and Fe heavy metal concentrations were determined in the mussel at six selected stations, namely Hamzakoy (Station 1), Gelibolu Tersanesi (2), Kilya Koyu (3), Eceabat cam Burnu (4), Kilitbahir (5) and Buyuk Kemikli Burnu (6). These mussel samples were collected six times in 2009, 2010, 20122013 during winter, spring, summer and autumn seasons. Zinc (19.15 mu g/g) is at the highest level in spring 2010 and Pb (0.05 mu g/g) has the lowest in winter 2010. While maximum values of the heavy metal concentrations are observed at Station 2, the minimum values are from Station 6. All stations are associated with mean seasonal values: Station 2> Station 3 > Station 4> Station 5 > Station 1 > Station 6. There were significant differences between heavy metal concentrations among the first four seasons (p<0.05). Values determined as seasonal averages (Fe > Zn > Cu > Pb) have been discussed, based on Anonymous, FAO, WHO/FAO, EPA, TME data and previous studies in the region, within the limits of the northern Aegean and southern Marmara Sea. In conclusion, it is suggested that these heavy metal levels do not pose an environmental risk in Canakkale Strait.Öğe New host findings of two parasitic isopods (Flabellifera: Cymothoidae) found on some fish caught in the Dardanelles Strait (Çanakkale, Turkey)(2022) Aldık, Ruhay; Öktener, Ahmet; Çakır, Fikret; Şen, Yusuf; Uğur, Gençtan Erman; Tuncer, SezginerSeven cymothoid species are identified in parasitological studies conducted in the Dardanelles Strait between May 2018- May 2020.The Cymothoids identified are as follows: Mothocya epimerica Costa, 1851, Nerocila bivittata (Risso, 1816), Anilocra frontalis H. Milne Edwards, 1840, Ceratothoa oestroides (Risso, 1826), Ceratothoa parallela (Otto, 1828), Ceratothoa italica Schiödte & Meinert, 1883, Emetha audouini (H. Milne Edwards, 1840).A. frontalis and C. italica are found for the first time from Sciaena umbra Linnaeus, 1758 and Boops boops (Linnaeus, 1758) respectively.Although several reports of these parasites have been given from Turkey, the morphological characters of three species have not been given.The drawings, descriptions of the mouthparts, pereopods, and pleopods of N. bivittata, A. frontalis, C. italica are given in this study.Öğe NEW RECORD OF ELONGATE LANTERNFISH, NOTOSCOPELUS ELONGATUS (COSTA, 1844), FROM THE COASTAL WATERS OF AEGEAN SEA, TURKEY, WITH NOTES ON SPECIES' MORPHOLOGY AND DISTRIBUTION(Wydawnictwo Akad Rolniczej W Szczecinie, 2009) Tuncer, Sezginer; Orlov, Alexei; Ozen, Ozcan; Bilgin, SabriBackground. Marine ichthyofauna of the Mediterranean Sea is represented by 712 species, 117 of which are deepwater fishes. During the last decade, this ichthyofauna has been considerably enriched, either by Suez Canal-or Strait of Gibraltar migrations or simply by mariculture escapees. This study is intended to discussed morphology of one of such non-indigenous fish species and its distribution. Materials and Methods. Three specimens of elongate lanternfish, Notoscopelus elongatus (Costa, 1844), were captured during a commercial lift net operation in Ece Limani, Aegean Sea, Turkey. The fish were described and illustrated, following commonly accepted procedures. Results. This is the first documented new record of the species from Aegean Sea, Turkey. The described meristic and morphometric features of elongate lanternfish, Notoscopelus elongatus, are consistent with the data provided by descriptors of its previous findings (with minor exceptions). The most interesting morphological feature of the presently described material is the presence in the smaller specimen (TL 103 mm) of 4 precaudal photophores (Prc) on the left body side (in contrast to 3 usual ones). Conclusion. This work will undoubtedly enhance our knowledge oil newly introduced species on lanterfishes in the Mediterranean and in Aegean Sea in particular.Öğe NEW RECORDS OF TWO SPECIES OF AMPHIPODS, MELPHIDIPPELLA MACRA (NORMAN, 1869) AND MONOCOROPHIUM SEXTONAE (CRAWFORD, 1937) FOR TURKISH SEAS(Brill Academic Publishers, 2009) Aslan-Cihangir, Herdem; Sezgin, Murat; Tuncer, Sezginer[Anstract Not Available]Öğe Occurence of the Thermophilic Mediterranean Parrot Fish Sparisoma cretense (Linneaus, 1758) (Teleostei: Scaridae) in Dikili Bay, Northern Aegean Sea, Turkey(2020) Tuncer, Sezginer; Torcu, Hatice Koç; Kanat, Rıdvan ErdemOn November 2019, one mature male specimen of the Mediterranean parrotfishSparisoma cretense (L.) was caught by a long line in Dikili Bay.
