Öğe First record of Paraprionospio coora Wilson, 1990 (Polychaeta: Spionidae) from the Mediterranean Sea(Natl Centre Marine Research, 2010) Yokoyama, H.; Dagli, E.; Cinar, M. E.The spionid polychaete Paraprionospio pinnata (Ehlers, 1901) has been widely reported from the Mediterranean Sea. We examined some specimens belonging to the genus Paraprionospio that had been collected from the Aegean Sea, the Sea of Marmara and the Spanish Mediterranean coast, and identified them as Paraprionospio coora Wilson, 1990, which is new to the Mediterranean fauna. This finding indicates that P. coora, has a widespread geographical distribution in Australia, the Far East and the Mediterranean, and suggests that the previous records of P. pinnata from the Mediterranean are questionable.Öğe Polychaetes from the northern part of the Sea of Marmara with the description of a new species of Polydora (Annelida: Polychaeta: Spionidae)(Natl Centre Marine Research, 2015) Cinar, M. E.; Dagli, E.; Caglar, S.; Albayrak, S.Soft-bottom material collected from the northern part of the Sea of Marmara (off Kucukcekmece) included a total of 67 species belonging to 24 polychaete families. Three species (Brania pusilla, Lysidice cf. margaritacea and Sabellaria spinulosa) are new records for the Sea of Marmara. Three alien species (Polydora cornuta, Prionospio pulchra and Pseudopolydora paucibranchiata) were found at the shallow-water stations. Different polychaete assemblages occurred in the area and the mud percentage of sediment and salinity were the main factors related to their distribution. A new Polydora species, which is mainly characterized in having brownish pigmentation solely on the antero-dorsal sides of the body, and falcate major spines with only a bulge (anterior ones) or with a bulge and a small tooth, is described.Öğe Spionidae (Annelida: Polychaeta) from the Aegean Sea (eastern Mediterranean)(Taylor & Francis Ltd, 2011) Dagli, E.; Cinar, M. E.; Ergen, Z.The present paper deals with spionid species (Spionidae) collected from various depths (4-183 m) and biotopes at 100 stations along the eastern part of the Aegean Sea in June-September 2000. A total of 35 species and 16 genera were identified, of which two species (Laonice norgensis and Spiophanes algidus) are new to the Mediterranean fauna, two species (Laonice bahusiensis and Polydora agassizi) are new to the eastern Mediterranean fauna, three species (Prionospio (Prionospio) saccifera, P. (P.) depauperata and Spiophanes afer) are new to the fauna of the Aegean Sea and four species are new to the fauna of Turkey. Prionospio (Prionospio) fallax and P. (P.) steenstrupi were represented by the highest dominance values, and Laonice cirrata and P. (M.) cf. multibranchiata by the highest frequency index values. The maximum number of species (28) were found on muddy bottom at 5-25 m. Nine species [Laonice norgensis, Paraprionospio coora, Polydora cornuta, Prionospio (Prionospio) depauperata, P. (P.) saccifera, P. (Minuspio) pulchra, Pseudopolydora paucibranchiata, Spiophanes algidus and Streblospio gynobranchiata] can be classified as alien.Öğe An updated review of alien species on the coasts of Turkey(Natl Centre Marine Research, 2011) Cinar, M. E.; Bilecenoglu, M.; Ozturk, B.; Katagan, T.; Yokes, M. B.; Aysel, V.; Dagli, E.; Acik, S.; Ozcan, T.; Erdogan, H.This 2010 review of alien species along the coasts of Turkey represents a total of 400 alien species belonging to 14 systematic groups. The present paper also reports the first findings of Vanderhorstia mertensi in the Aegean Sea (Gokova Bay), Chama adspersa in the Sea of Marmara and Mya arenaria in the Aegean Sea. A total of 124 new alien species was determined within the last 5 years. Mollusca had the highest number of species (105 species), followed by Polychaeta (75 species), Crustacea (64 species) and Pisces (58 species). The highest number of alien species (330 species) were encountered on the Levantine coast of Turkey, followed by the Aegean Sea (165 species), Sea of Marmara (69 species) and Black Sea (20 species). The Suez Canal (66% of the total number of alien species) is the main vector for species introductions to the coasts of Turkey, followed by the shipmediated transport (30%). The majority of species (306 species, 76% of total number of species) have become established in the area, while 59 species are classified as casual (15%), 23 species as questionable (6%) and 13 species as cryptogenic (3%). One new alien species was introduced to the coasts of Turkey every 4 weeks between 199:1 and 2010. The majority of aliens were found on soft substratum (198 species) in shallow waters (0-10 m) (319 species). Some species such as Caulerpa racemosa, Amphistegina lobifera, Amphisorus hemprichii, Rhopilema nomadica, Mnemiopsis leidyi, Hydroides spp., Ficopomatus enigmaticus, Charybdis longicollis, Rapana venosa, Asterias rubens, Siganus spp. and Lagocephalus sceleratus show a highly invasive character, and have great impacts both on the prevailing ecosystems and humans.
