Facies Along the Aegean Coasts of Turkey(Turkish Journal of Zoology, 2005) Kırkım, Fevzi; Kocataş, Ahmet; Katağan, Tuncer; Sezgin, Murat; Ateş, Abdullah SuatThis research was carried out to determine the crustacean species associated with Padina pavonia facies distributed in the upper-infralittoral zone of the Aegean Sea coasts of Turkey and their bioecological features. The investigations were performed at depths of 2-5 m in 13 different stations chosen in the Aegean Sea in June and July, 1995. As a result of the study, a total of 3279 specimens belonging to 85 species were identified. Of these, Ampithoe ramondi was commonest with a dominance value of 21.47%, followed by Elasmopus pocillimanus with 13.94% and Ericthonius brasiliensis with 4.61%.Öğe Crustacean Diversity Among the Cystoseira Facies of the Aegean Coast of Turkey(Turkish Journal of Zoology, 2004) Kocataş, Ahmet; Katağan, Tuncer; Sezgin, Murat; Kırkım, Fevzi; Koçak, CengizThis study focused on the crustacean fauna of Cystoseira facies in the upper infralittoral zone of the Turkish Aegean coast. Investigations were carried out at 9 stations along a depth gradient of 2 to 5 m in June and July 1995. A total of 2179 specimens belonging to 81 species were identified. Among the species encountered, Ampithoe ramondi was the most common, with a dominance value of 11%, followed by Leptochelia savignyi (7%). Caprella rapax is recorded for the first time from the Aegean coast of Turkey; Corophium acutum, Corophium rotundirostre and Hippolyte varians are new records for the entire Turkish coast.Öğe Decapod crustaceans on the Gökçeada (Imbros) island continental shelf (north-eastern Aegean Sea)(Mediterranean Marine Science, 2006) Ateş, Abdullah Suat; Katağan, Tuncer; Kocataş, AhmetThe present composition of decapod crustaceans found at the sublittoral depths (5-104 m) off the coast of the island of Gökçeada (north-eastern Aegean Sea) is presented. A total of 28 species (11 caridean shrimps, 1 thalassinid ghost crab, 7 anomurans and 9 brachyuran crabs) and 277 specimens were recorded. The caridean shrimp, Athanas nitescens had the highest abundance with a dominance value of 20.94% in samples. The dominant group is caridean, represented by a total of 11 species and an occurrence frequency of 39.29%.Öğe Exotic crustaceans of the Turkish coast(Arthropods, 2013) Ateş, Abdullah Suat; Katağan, Tuncer; Sezgin, Murat; Özcan, TahirA total of 50 exotic species (19 Brachyura, 19 Natant ia, 2 Stomatopoda , 6 Amphipoda, 1 Cumacea, 2 Isopoda, and 1 Cirripedia) of crustaceans are reported from the Tu rkish coast. Exotic crustaceans of the Turkish Seas comprises of approximately 48% of the fauna constituted by invasive species, introduced from the Levantine basin of the Mediterranean. About 34% of invasive crustaceans found on the Turkish coast are Indo-west Pacific origin. Decapods constitute majority of the species with a dominance of 38%. Lowest dominace (2%) was related to orders, Cumacea and Cirripedia a being that were represented by single species. When Levantine basin was compared to the Turkey coast, th e shrimp species reported on the Turkish coast were 70% of the shrimp species of all Levantine basin. The exotic migrant crab of Indo-West Pacific, Charybdis helleri was found abundant on the entire Turkish coas t of the Mediterranean. Brachyuran crab, Eurycarcinus integrifrons and the oisk shrimp, Palaemonella rotumana are the latest records of exotics for the Turkish Seas.Öğe First record of a bathyal leptostracan, Nebalia abyssicola Fage, 1929 (Crustacea: Malacostraca: Phyllocarida), in the Aegean Sea, eastern Mediterranean(Turkish Journal of Zoology, 2012) Moreira, Juan; Sezgin, Murat; Katağan, Tuncer; Gönülal, Onur; Topaloğlu, BülentData on deep sea leptostracans (Crus tacea: Phyllocarida: Leptostraca) are still scarce in many parts of the world. In the last few years, several species of Nebalia Leach, 1814, have been reported from the eastern Mediterranean; however, there have been no reports from waters deeper than 100 m. Samples collected recently from Gökçeada, Turkey—at depths of 680-820 m in the Aegean Sea, eastern Mediterranean—included Nebalia abyssicola Fage, 1929. This is the first record for the study area and one of the few known records of this species. Specimens are described and figured to complement previous descriptions. A key for all known leptostracans from the eastern Mediterranean is also provided.Öğe New Mediterranean Marine biodiversity records (June 2013)(Mediterranean Marine Science, 2013) Siokou, I.; Ateş, Abdullah Suat; Ayas, D.; Souissi, J. Ben; Chatterjee, T.; Dimiza, M.; Durgham, H.; Dogrammatzi, K.; Erguden, D.; Gerakaris, V.; Grego, M.; Issaris, Y.; Kadis, K.; Katağan, Tuncer; Kapiris, K.; Katsanevakis, S.; Kerckhof, F.; Papastergiadou, E.; Pesic, V.; Polychronidis, L.; Rifi, M.; Salomidi, M.; Sezgin, Murat; Triantaphyllou, M.; Tsiamis, K.; Turan, C.; Tziortzis, I.; D’acoz, C. D’udekem; Yağlıoğlu, D.; Zaouali, J.; Zenetos, A.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 relevant countries: the red alga Sebdenia dichotoma (Greece), the hydrachnid mite Pontarachna adriatica (Slovenia), and the thalassinid Gebiacantha talismani (Turkey). Several alien species were recorded in new Mediterranean localities. The record of the burrowing goby Trypauchen vagina in the North Levantine Sea (Turkish coast), suggests the start of spreading of this Lessepsian immigrant in the Mediterranean Sea. The findings of the following species indicate the extension of their occurrence in the Mediterranean Sea: the foraminifer Amphistegina lobifera (island of Zakynthos, Greece), the medusa Cassiopea andromeda (Syria), the copepod Centropages furcatus (Aegean Sea), the decapod shrimp Melicertus hathor (island of Kastellorizo, Greece), the crab Menoethius monoceros (Gulf of Tunis), the barnacles Balanus trigonus, Megabalanus tintinnabulum , Megabalanus coccopoma and the bivalves Chama asperella , Cucur - bitula cymbium (Saronikos Gulf, Greece).Öğe Notes on amphipods Caprella andreae Mayer, 1890 and Podocerus chelonophilus (Chevreux & Guerne, 1888) collected from the loggerhead sea turtle, Caretta caretta, off the Mediterranean and the Aegean coasts of Turkey(Turkish Journal of Zoology, 2009) Sezgin, Murat; Ateş, Abdullah Suat; Katağan, Tuncer; Bakır, Kerem; Özdilek, Şükran YalçınThe present study reports the occurrence of 2 amphipod species, Caprella andreae Mayer, 1890 and Podocerus chelonophilus Chevreux & Guerne, 1888, that appeared on the carapace of the loggerhead turtle Caretta caretta (Linnaeus, 1758) in the eastern Mediterranean Sea (Levantine Sea). The amphipod specimens were found on a male Caretta caretta captured during experimental bottom studies conducted off Samandağ, Hatay (the Turkish Mediterranean coast) on 7 April 2007. In addition, Caprella andreae Mayer 1890 was collected from the nets of fish cages off the Seferihisar (Aegean Sea) coast (38°11 ?32 ?N, 26°38 ?07 ?E). C. andreae is a first report for the amphipod fauna in Turkish seas.Öğe On the presence of the non-native estuarine shrimp, Palaemon longirostris H.Milne-Edwards, 1837 (Decapoda, Caridea), in the Black Sea(Journal of Aquatic Invasions, 2007) Sezgin, Murat; Aydemir, Eylem; Ateş, Abdullah Suat; Katağan, Tuncer; Özcan, TahirThe non-native estuarine shrimp, Palaemon longirostris H.
