Öğe Contributions to the biodiversity of sea slugs and shelled relatives of the Sea of Marmara (Mollusca: Gastropoda)(Cahiers De Biologie Marine, 2018) Artuz, M. 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 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 On the association of carangid juveniles, Alepes djedaba, with the jellyfish Rhizostoma pulmo(Soc Francaise D Ichtyologie, 2017) Artuz, M.
