This work presents information about 19 taxa recorded from different habitats at depths between 0.2 and 508 m in the last two decades, which are new records or poorly known species along the Turkish coasts. Among the identified species, Epitonium vaillanti, Melanella cf. lubrica, Melanella monterosatoi, Pelseneeria minor, Setia amabilis, Kurtziella serga, Rissoella diaphana, Rissoella inflata, and Spirolaxis clenchi are new records for the Turkish mollusc fauna, Eatonina pumila is new report for the Turkish coast of the Aegean Sea, and Eatonina ochroleuca, Acirsa subdecussata, Lamellaria latens, Setia pulcherrima, Setia valvatoides, and Turbonilla cangeyrani are species with rare distribution which were sampled for one or a few times only. Viriola cf. bayani, Acirsa subdecussata, Melanella monterosatoi, Eatonina ochroleuca, E. pumila, Setia amabilis, Setia pulcherrima, Lamellaria latens, Rissoella diaphana, R. inflata, and Syrnola sp. were encountered along the Aegean Sea coast, whereas Epitonium vaillanti, Pelseneeria minor, Rissoidae sp., Kurtziella serga, Turbonilla cangeyrani, and Spirolaxis clenchi were recorded on the Levantine coast of Turkey, and Melanella cf. lubrica in the prebosphoric region of the Sea of Marmara. Setia valvatoides is the only species found on the Turkish Black Sea coast. On the other hand, Epitonium vaillanti and Viriola cf. bayani are species originated outside the Mediterranean basin. Most of the species were found at infralittoral and circalittoral depths, except for Kurtziella serga and Spirolaxis clenchi found at a depth of 508 m. The present study elucidates some ecological and distinguishing characteristics of the investigated species, along with their colour photographs and distribution along the Turkish coasts.

Ilerdian (early Eocene) carbonates in the northwestern Tosya region, northern Turkey, are characterized by porcellaneous larger benthic foraminifera; Glomalveolina, Alveolina, Orbitolites, Opertorbitolites and Cyclopertorbitolites are common in the southeastern Kastamonu region, in facies deposited on a low-gradient carbonate ramp. The inner ramp comprises of Miliolid-soritid wackestone, Soritid wackestone, Alveolinid-soritid wackestone-packstone, Alveolinid wackestone, Alveolinid-Nummulitid wackestone-packstone, algal wackestone, and Coralline algal pack-grainstone microfacies. The middle ramp deposits are composed of Alveolinid-nummulitid wackestone-packstone and Nummulitid wackestone-packstone microfacies. Overall, the succession reflects a long term deepening trend.

The present study deals with macrozoobenthic species on soft substrates in İğneada (Turkish coast of the Black Sea). Benthic samples were collected seasonally at three stations between 2012 and 2013. A total of 155 species belonging to seven taxa (Turbellaria, Nemertea, Nematoda, Oligochaeta, Polychaeta, Crustacea, Phoronida, Mollusca, Hemichordata) were identified. Of these, four species are new records for the Black Sea fauna, 15 species are new to the Turkish coast of the Black Sea; and two species are new to the Turkish Seas. Polychaeta was the most representative taxon in the study area -- it was represented by 58 species (39% of the total number of species). In terms of the number of individuals, Mollusca were the dominant taxon in all seasons (82% of the total number of individuals). The most dominant species were Bittium reticulatum and Caecum trachea and the most frequent species were Micronephtys stammeri, B. reticulatum and Chamelea gallina. [ABSTRACT FROM AUTHOR]

Akdeniz and Akbuk lagoons are part of a shallow coastal ecosystem of great aesthetic and ecological importance, located in Muğla Province in the southern Aegean region of Turkey. In the present study, four expeditions to collect ostracods from these lagoons were conducted in May, July, October, and November of 2008. Benthic samples were obtained monthly and several environmental factors were recorded simultaneously in situ. The ecological preferences of the ostracods were monitored, and qualitative and quantitative samples were collected from three sites in Akdeniz lagoon and two sites in Akbuk lagoon. Three ostracod taxa (Cyprideis torosa, Loxoconcha elliptica and Cytherois fischeri) were identified from the Akdeniz lagoon sampling sites and one species (Cyprideis torosa) from the Akbuk lagoon sampling sites. We present and analyze the dominance and distribution of ostracod assemblages and their relationships to environmental factors: temperature, dissolved oxygen, percentage oxygen saturation, pH, redox potential, salinity, and electrical conductivity) using classification and ordination techniques. Canonical correspondence analysis (CCA) is used to characterize the relationship between ostracods and the environmental variables. Approximately 82% of the correlation between the community composition and environmental variables was explained by the first axis of the CCA ordination for the Akdeniz lagoon. The study revealed that the distribution and population density of ostracod species depends on the physicochemical properties of the environment. The reason for this is that Cyprideis torosa and Loxoconcha elliptica are euryhaline species. [ABSTRACT FROM AUTHOR]
