New records of recent Ostracoda (Crustacea) for the marine fauna of Turkey

Abstract A total of 60 species of Ostracoda was collected from 30 locations in the Turkish Aegean Sea. Five species, Polycope vasfiensis Sissingh, Leptocythere bituberculata Bonaduce, Ciampo & Masoli, Loxoconcha gibberosa Terquem, Sagmatocythere versicolor (Müller) and Monoceratina oblita Bonaduce et al., are new records for the recent marine fauna of the North Aegean Sea and Turkey.

The ontogeny of appendages of Heterocypris salina (Brady, 1868) Ostracoda (Crustacea)

The post-embryonic development of the appendages of the Cyprididae ostracod Heterocypris salina (Brady, 1868) are described in detail and compared with those of other podocope species documented in previous studies. Generally, the appearence of limbs during onotgeny of H. salina is similar to that of other species, but small differences in limb morphologies were identified between H. salina and other Cyprididae species, including other Heterocypris species. Some features appear either earlier or later in the development of H. salina compared with other species, even species of the same genus. These features may be useful characters for phylogenetic analyses at the genus and family levels.

Two new species of Stenosoma(Isopoda, Idoteidae) from the Sea of Marmara

Two new species of isopod crustaceans belonging to the genus Stenosoma Leach, 1814 (Valvifera, Idoteidae) are described, illustrated, and compared with the other known species of the genus. The new species can be distinguished both from each other and from all their congeners by having a maxilliped with two coupling hooks; length of the appendix masculina on pleopod II; and an antennal flagellum with 12 articles in Stenosoma aaseni sp. nov.; and by having a pair of distinctive lateral spinous tubercles on pereonites I-II; and a pereon with a part of a mid-dorsal carina on the posterior half of each of the pereonites in Stenosoma inonuei sp. nov.; the two new species also differ in the morphology of mouthparts, pleotelson, and pereopods. Both new species were collected from seagrass meadows, colonized predominantly by Zostera ( Zostera ) marina Linnaeus, 1753 and Posidonia oceanica (Linnaeus) Delile, 1813, in the Sea of Marmara, Turkey. An up-to-date morphological identification key to species level for to genus Stenosoma is also provided.

Cytherella maremensis sp. n., a new ostracod from the Sea of Marmara (Turkey) (Crustacea: Ostracoda)

Cytherella maremensis sp. n., belonging to the family Cytherellidae, is described as new from a hydrothermal vent, located in the west of Marmara Island on the North Anatolian Fault crossing the Sea of Marmara. It was collected from a sediment core 55 m below sea level. Cytherella maremensis sp. n. is clearly separated from closely related species by its shape, length-height ratio and ornamentation.

The complete mitochondrial genome of Alburnus tarichi (Teleostei, Cyprinidae)

Abstract Alburnus tarichi is the only vertebrate species that can survive in Lake Van, the largest soda lake on Earth, which is characterized by extremely high pH and salinity. The circular mitogenomes of A. tarichi was 16,602 base pairs in size, containing 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes, and 2 major non-coding control regions (D-Loop and OL). Congurence was observed between the Alburnus mtDNAs in terms of genome organization, base composition, gene arrangement, and tRNA structure. Mitogenome sequences may be useful for conservation efforts of this endangered species.

Complete mitochondrial genome of Alburnus istanbulensis (Teleostei, Cyprinidae)

Abstract Alburnus istanbulensis (Thracian shemaya) is an endemic fish species to the northwestern region of Turkey. Alburnus istanbulensis has a remarkably limited geographic distribution, and no genetic data have been available on this species until now. The mitogenome (16,612 bp) had the typical mitochondrial characteristics of other Leuciscinae fishes. This mitogenome sequence can help to further resolve phylogenetic relationships among Cyprinidae.

First record of Monodaeus guinotae Forest, 1976 (Decapoda, Brachyura) in the Sea of Marmara (Turkey) and a discussion about its occurrence

A total of 24 specimens of Monodaeus guinotae Forest, 1976 were obtained in beam-trawl surveys on 8 August 2008, 2 August 2011 and 4 August 2011 at depths of 56, 65 and 40 m, respectively, in the Sea of Marmara. M. guinotae is reported in this study as a first record for the Sea of Marmara and the status of the species is discussed in relation to its closely similar congener, M. couchii (Couch, 1851). Also, possible reasons for its occurrence are investigated according to the effects of pollution and of the various water masses in the Sea of Marmara.
