Suat[Anstract Not Available]Öğe An updated list of decapod crustaceans on the Turkish coast with a new record of the Mediterranean shrimp, Processa acutirostris Nouvel and Holthuis 1957 (Caridea, Processidae)(Univ Oradea Publ House, 2010) Ates, Abdullah Suat; Kocatas, Ahmet; Katagan, Tuncer; Ozcan, TahirThe present paper includes an updated list of the decapod crustaceans collected during the surveys performed on the Turkish coast. A total of 244 species was reported (88 Natantia, 17 Macrura Reprantia, 37 Anomura, 102 Brachyura), an increase of 9.84% over the number published by Kocatas & Katagan (2003). Zoogeographic remarks regarding the species are briefly discussed. The Mediterranean caridean shrimp, Processa acutirostris Nouvel and Holthuis, 1957 recently collected from the Turkish Mediterranean coast is a new record for the Turkish Seas. The following nomenclature is also up to date based on the Marine Species (Worms, 2008)Öğe COMMERCIAL CRUSTACEANS ON THE LEVANTINE SEA COAST OF TURKEY(Turkish Marine Research Foundation-Tudav, 2016) Ozcan, Tahir; Ates, A. Suat; Bakir, Kerem; Katagan, Tuncer[Anstract Not Available]Öğe COMMERCIAL DECAPOD AND STOMATOPOD CRUSTACEANS IN THE TURKISH AEGEAN SEA(Turkish Marine Research Foundation-Tudav, 2015) Ates, A. Suat; Ozcan, Tahir; Katagan, Tuncer[Anstract Not Available]Öğe Decapod crustaceans of soft-sediments on the Aegean Sea coast of Turkey (the eastern Aegean Sea)(Univ Gdansk, 2008) Ates, A. Suat; Katagan, Tuncer58 species of decapod crustacean were identified (1 Dendobranchiata, 14 Caridea, 5 Thalassinidea, 14 Anomura, 24 Brachyura) on soft substrates of the Aegean Sea coast of Turkey. Samples were collected from 60 sampling sites along the Turkish Aegean shore (eastern Aegean Sea) between July 2000 and September 2000 with dredge and a van Veen grab at bottom depths of 7 to 150 m. Different species dominated in each ecological zone with the anomuran squat lobster, Galathea intermedia Lilljeborg, 1851, being the most dominant species across the whole sampling area, comprising 11.71% of the individuals collected. This report represents the first published investigations into soft-sediment decapod communities in the coastal waters of the Turkish Aegean Sea.Öğe Decapod Crustaceans on the Coast of Gokova Bay (the southeastern Aegean Sea)(Ege Univ, 2007) Ates, A. Suat; Katagan, Tuncer; Kocatas, AhmetThe present study is on decapod crustaceans found on the coast of Gokova Bay (the southeastern Aegean Sea). A total of 358 specimens belong to 51 species (17 carideans, 11 anomurans, 1 thalassinid, and 22 brachyurans) was collected during experimental benthos samplings in the area. The brachyuran crabs was dominant component of decapod assemblage in the area by a total of 22 species and an occurrence frequency of 43,13%. The caridean shrimp, Lysmata seticaudata (Risso, 1816) was most dominant species by dominance value of 19,83%.Öğe FIRST RECORD OF PARASQUILLA FERUSSACI (ROUX, 1828) (STOMATOPODA, PARASQUILLIDAE) FROM THE TURKISH COASTS(Brill Academic Publishers, 2008) Oezcan, Tahir; Katagan, Tuncer; Irmak, Erhan[Anstract Not Available]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(Tubitak Scientific & Technological Research Council Turkey, 2009) Sezgin, Murat; Ates, A. Suat; Katagan, Tuncer; Bakir, Kerem; Yalçın Özdilek, ŞükranThe 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 Samandag, 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 degrees 11'32 '' N, 26 degrees 38'07 '' E). C. andreae is a first report for the amphipod fauna in Turkish seas.Öğe On the occurrence of the Mediterranean endemic majid crab, Inachus parvirostris (Risso, 1816) (Decapoda, Brachyura, Majidae) in Turkish seas(Brill Academic Publishers, 2008) Ates, A. Suat; Ozcan, Tahyr; Katagan, Tuncer[Anstract Not Available]Öğe Relationships of benthic amphipod communities with environmental variables in the shallow waters of the Dardanelles(Walter De Gruyter Gmbh, 2012) Ates, A. Suat; Sezgin, Murat; Katagan, Tuncer; Ozdilek, H. Goksel; Berber, Selcuk; Kolsal, Secil; Bircan, CuneytThe structure of the benthic amphipod assemblage and its relationship with soft-bottom characteristics (particle size, organic matter, etc.) of the coastal waters at the depths of 0-5 m at the Dardanelles, including the Turkish Straits System, was studied. A SCUBA diver took benthos and sediment samples seasonally using a quadrate system of 30x30 cm as three transects from the 8 different stations between July 2008 and April 2009. A total of 3007 individuals belonging to 50 species was reported. Among these, Corophium acutum Chevreux, 1908 had the highest dominance value (Di%=22.18) and the lowest dominance value belonged to Dexamine thea Boeck, 1861 (Di%=0.03). The highest positive correlation (r(s)=0.57, p < 0.05) was observed between the gravel content (%) and the abundance (ind. m(-2)). The highest sand rate (99.59%) in the sediment was found at the Eceabat site. The lowest rate was at the Kepez Harbour station with a value of 73.01%. The highest H' value (1.53) was recorded at the Eceabat site, and the lowest H' value (H'=0.95) was recorded at the Gallipoli sampling station.Öğe Spatio-temporal distributions of zoobenthos in soft substratum of Izmir Bay (Aegean Sea, eastern Mediterranean), with special emphasis on alien species and ecological quality status(Cambridge Univ Press, 2012) Cinar, Melih Ertan; Katagan, Tuncer; Ozturk, Bilal; Bakir, Kerem; Dagli, Ertan; Acik, Sermin; Dogan, AlperThe soft-bottom zoobenthic community structure of Izmir Bay was examined seasonally at eight stations (depth-range: 19-67 m) in 2009. A total of 427 species were found. Polychaeta had the highest number of species (50% of total species) and individuals (7596), whereas Echinodermata possessed the highest biomass (47%). The number of species varied from 3 to 79 (0.1 m(-2)), the density from 60 to 5360 ind.m(-2), and the biomass from 1 to 530 g.m(-2). The most numerically dominant species were the polychaetes Aricidea claudiae, Streblospio gynobranchiata, Levinsenia demiri and Sternaspis scutata. The distribution of zoobenthos was strongly related to spatial differences in total organic carbon, sediment texture and depth among different regions of the bay rather than temporal differences among seasons. However, significant seasonal variability in community structure (mainly differences in the relative abundance of species) was present. The inner region of the bay can be classified as 'poor' or 'bad' based on the results of biotic indices (H', AMBI, m-AMBI and BENTIX). Among biotic indices, only H' and m-AMBI appeared to be capable of explaining the bay's benthic quality status. Thirteen alien species were also found. Streblospio gynobranchiata, Prionospio pulchra, Pseudopolydora paucibranchiata and Polydora cornuta formed dense populations in the inner most polluted part of the bay and are considered to be new pollution indicator species in the eastern Mediterranean Sea.Öğe The marine arthropods of Turkey(Tubitak Scientific & Technological Research Council Turkey, 2014) Bakir, Ahmet Kerem; Katagan, Tuncer; Aker, Halim Vedat; Ozcan, Tahir; Sezgin, Murat; Ates, Abdullah Suat; Kocak, CengizThis recent checklist of marine arthropods found on the coasts of Turkey represents a total of 1531 species belonging to 7 classes: Malacostraca (766 species), Maxillopoda (437 species), Ostracoda (263 species), Pycnogonida (27 species), Arachnida (26 species), Branchiopoda (7 species), and Insecta (5 species). Seventy-five species were classified as alien species in the region. This paper also includes the first record of the amphipod Melita valesi from the Levantine coast of Turkey (Kas, Gulf of Antalya).Öğe The Response of Apseudopsis latreillii (Milne-Edwards, 1828) (Crustacea, Tanaidacea) to Environmental Variables in the Dardanelles(Central Fisheries Research Inst, 2014) Ates, A. Suat; Katagan, Tuncer; Sezgin, Murat; Acar, SecilThe tanaid, Apseudopsis latreilli (Milne-Edwards, 1828) is a common crustacean species on the soft bottoms of the Mediterranean ecosystems and occurs in both clean and polluted environments. This study was aimed to determine the sensitive state of tanaid, A. latreillii to the environmental variables observed on the soft bottoms of the Dardanelles. A. latreillei abundance at the sites was analysed in comparision with the organic matter content in sediment and the environmental variables in the study area. A total of 1406 specimens of A. latreillii was recorded during the study. The highest dominance value (Di=30.37%) was for Kepez Harbour where the amount of organic matter was 25.50 +/- 12.09% in the sediment. The highest value of dominance according to the sampling seasons was 56.75% for Autumn 2008 (organic matter=21.7 +/- 7.99%). The highest sand rate (99.59%) in the sediment was found at the Eceabat sampling point. The highest positive correlation (r=0.349, P<0.05) was observed between gravel content (%) measured at the sites and total abundance (ind. 0.09 m-2).Öğe Two new records of caridean shrimps from Turkish waters: Eaulus sollaudi (Zariquiey Cenarro, 1935) (Caridea, Hippolyte) and Palaemonella rotumana (Borradaile, 1898) (Caridea, Palaemonidae)(Tubitak Scientific & Technological Research Council Turkey, 2009) Ates, A. Suat; Bakir, Kerem; Ozcan, Tahir; Katagan, TuncerThis paper concerns 2 new shrimp records, Eualus sollaudi (Zariquiey Cenarro, 1935) and Palaemonella rotumana (Borradaile, 1898), found during sampling performed by scuba divers near the coast in Fethiye Bay (the eastern Mediterranean, Turkey) in June and July 2008.
