Türkiye kıyılarında ilk kez rastlanan Hemichortada filumunu' nun iki türü [Balanoglossus clavigerus delle chiaje, 1829, Glandiceps talaboti (Marion, 1876)]

Bu çalışmada, Türkiye denizlerinde bulunurluğu daha önce rapor edilmemiş Hemichordata filumu ve bu filuma ait iki tür Balanoglossus davigerus (Enteropneusta-Ptychoderidae), Glandiceps talaboti (Enteropneusta-Spengelidae) kuzeydoğu Akdeniz'den (Yumurtalık koyu ve Babadıl limanı) rapor edilmektedir.In this study, for the first time, 2 species (Baianoglossus davigerus delle Chiaje, 1829 and Glandiceps talaboti (Marion, 1876)) belonging to the phylum Hemichortada, which have not previously been encountered in Turkish seas, are recorded from the northeastern Mediterranean Sea (Yumurtalık Bight, and Babadil port)

MtDNA genleri kullanarak türk deniz sularında tirsi türlerinin (Alosa spp.) moleküler sistematik analizi

Türk deniz sularından beş tirsi türünün (Alosa caspia, A. fallax nilotica, Alosa maeotica, Alosa immaculata, Alosa tanaica) filogenetik ilişkisi mitokondriyal DNA polimeraz zincir reaksyionu-restriksiyon parça uzunluk polimorfizmi ile araştırılmıştır. PCR ile uygulamaya tabi tutulmuş altı gen bölgesi; NADH 5/6, NADH 3/4 cytochrom b, COX, 16 S rRNA ve D-Loop, yedi restriksiyon enzimi ile (BsurI, AluI, EheI, Hin6I, RsaI, XhoI Bsh1236I) sırasıyla kesilmiştir. Filogenetik analiz için bir araya getirilmiş altı genden toplam 45 haplotip beş tirsi türünden tespit edilmiş ve ortalama haplotip çeşitliliği ile türler içerisindeki nükleotit çeşitliliği sırasıyla 0,8809 ve 0,0022 olarak bulunmuştur. En yüksek genetik farklılık A. caspia ve A. maeotica (0,013727) arasında, en düşük A. immaculata ve A. tanaica (0,003073) arasında gözlenmiştir. Monte Carlo (X 2 ) ikili genetik karşılaştırma sonucunda tüm türler arasında yüksek derecede önemli farklılıklar ortaya çıkmıştır (P<0,001). Komşu katılımlı ağaçta oluşan iki ana grupta; birinci grup A. caspia ve A. f. nilotica genetik benzerlik olarak birbirine çok yakın görülürken, A. immaculata.bu gruba kardeş grup olmuştur. A. tanaica ise bu grubun içerisinde bir hayli farklı görünmektedir. Alosa cinsi arasında en yüksek genetik farklılaşma gösteren A. maeotica sadece diğer grup içerisinde yer almıştır.The phylogenetic relationship among five shad species (Alosa caspia, A. fallax nilotica, Alosa maeotica, Alosa immaculata, Alosa tanaica) from Turkish marine waters was investigated with mitochondrial DNA polymerase chain reaction-restriction fragment length polymorphism.The six genesegments, NADH 5/6, NADH 3/4cytochrome b, COX, 16 SrRNA and D-Loop, of mtDNA amplified by PCR were digested with seven restriction enzymes, BsurI, AluI, EheI, Hin6I, RsaI, XhoI Bsh1236I, respectively.When all the six genes were combined together for phylogenetic analysis, a total of 45 haplotypes were detected from the five shad species, and the average haplotype diversity and nucleotide diversity within species were 0.8809 and 0.0022 respectively. The average nucleotide diversity and nucleotide divergence among species were 0.009248 and 0.007080 respectively. The highest genetic divergence was observed between A. caspia and A. maeotica (0.013727) and the lowest between A. immaculate and A. tanaica (0.003073). Monte Carlo (X 2 ) pairwise genetic comparison revealed highly significant differences between all species (P&lt;0.001). In the Neighbour-joining tree, there were two main grouping, and in the first group, A. caspia and A. f. nilotica exhibited the closest genetic similarity which was the sister group to A. immaculata. A .tanaicaseems to be the most divergent in this grouping. Another group contained only A. maeotica which showed the highest genetic differentiation among Alosa genus

Comparative Study of the Length-Weight Relationships of Some Fish Species along the Turkish Coasts

This study presents 738 length-weight relationships for 242 species found in Turkish seas. All length-weight relationships presented were collected from a total of 33 studies. These studies were all performed in Turkish coastal waters between 1997 and 2013. For all studies, the median of a value was calculated as 0.014 and the median of b value was calculated as 3.016

Macrobenthic assemblages of newly introduced Caulerpa taxifolia from the Eastern Mediterranean coast of Turkey

Caulerpa taxifolia is one of the most important and best-studied alien species in the Mediterranean Sea. The present study reveals the macrobenthic assemblages associated with C. taxifolia from the region. We found 26 species from Polychaeta, 31 species from Crustacea, 22 species from Mollusca and 5 species from Echinodermata. In conclusion, C. taxifolia in A degrees skenderun Bay can be considered an ecosystem engineer that modifies local habitats and also enhances biodiversity

New Record of the Big-Scale Sand Smelt Atherina boyeri Risso, 1810 (Atherinidae) in the Seyhan Dam Reservoir (Seyhan River basin, Turkey)

Fifteen specimens of the big-scale sand smelt, Atherina boyeri were caught by a single trawl haul with a net mesh size of 3 mm on February 2017 from the Seyhan Dam Reservoir (South Anatolia, Adana/Turkey). In this study the big-scale sand smelt, A. boyeri, was recorded for the first time in the Seyhan Dam Reservoir. In addition, some morphometric and meristic measurements of A. boyeri were given and these values were compared to populations in two different lakes. Furthermore, the possible ecological effects of A. boyeri on Seyhan Dam Reservoir were briefly discussed
