Morphological Anomalies Observed on Vertebralina striata dOrbigny, 1826 Test in the Northern Coast of Karaburun Peninsula (Izmir-Turkey)
Morphological abnormalities have been observed on the test of recent foraminifer samples and
locally different ecological conditions, such as, hypersalinity, presence of heavy metals and thermal
springs are suggested to be the cause of this phenomenon. Abnormal test development, as well as
twins and triplets are commonly observed in natural and artificial saltpans which form hypersaline
environments. Submarine freshwater springs can cause extreme seasonal salinity variations on the
coastal regions which affects the benthic foraminifer species and results in the abnormal test
development. Vertebralina striata d’Orbigny individuals with abnormal aperture morphology have
been found in samples collected around the thermal springs in Çeşme-Ilıca Bay. More surprisingly,
specimens with similar aperture abnormality have also been observed in samples collected from
other two stations on the Karaburun Peninsula. Five of the abnormal specimens had two apertures
the others had three. A specimen collected from Ilıca Bay had two apertures, one of which is the
typical Vertebralina striata d’Orbigny aperture, but the other was distantly located and rounded.
Vertebralina striata d’Orbigny is widely distributed in world's seas, however such aperture
abnormalities has not been reported elsewhere. Observation of similar morphological abnormalities
in three distinct locations suggests a common cause. The submarine spring found in Ilıca Bay
supports the idea that spring waters affect the chemical composition of the seawater locally, leading
to this aperture abnormality

Based on recent biodiversity studies carried out in different parts of the Mediterranean, the following 19 species are included as new
records on the floral or faunal lists of the relevant ecosystems: the green algae Penicillus capitatus (Maltese waters); the nemertean Am-
phiporus allucens (Iberian Peninsula, Spain); the salp Salpa maxima (Syria); the opistobranchs Felimida britoi and Berghia coerulescens
(Aegean Sea, Greece); the dusky shark Carcharhinus obscurus (central-west Mediterranean and Ionian Sea, Italy); Randall’s threadfin
bream Nemipterus randalli, the broadbanded cardinalfish Apogon fasciatus and the goby Gobius kolombatovici (Aegean Sea, Turkey);
the reticulated leatherjack Stephanolepis diaspros and the halacarid Agaue chevreuxi (Sea of Marmara, Turkey); the slimy liagora Ganon-
ema farinosum, the yellowstripe barracuda Sphyraena chrysotaenia, the rayed pearl oyster Pinctada imbricata radiata and the Persian
conch Conomurex persicus (south-eastern Kriti, Greece); the blenny Microlipophrys dalmatinus and the bastard grunt Pomadasys incisus
(Ionian Sea, Italy); the brown shrimp Farfantepenaeus aztecus (north-eastern Levant, Turkey); the blue-crab Callinectes sapidus (Corfu,

Pinna nobilis in the south Marmara Islands (Sea of Marmara); it still remains uninfected by the epidemic and acts as egg laying substratum for an alien invader
A total of 12 Pinna nobilis beds were found and studied at depths varying between 2 and 6 m in the south Marmara Islands (Sea of Marmara). Fan mussel individuals in the beds were healthy with a few old dead specimens, indicating that the epidemic, which has devastated P. nobilis populations in the Mediterranean Sea, has not reached the Sea of Marmara, making the region a refuge area for the species. The average density of P. nobilis in the area varied between 0.6 ind.10 m(-2) and 24 ind.10 m(-2). The P. nobilis shells overall provided substrata or refuge for 14 species (10 sessile and 4 motile organisms), from macroalgae to fish. Shells of juvenile and adult specimens had different species assemblages. Four distinct assemblages were detected on shells, primarily formed by the red alga Gracilaria bursa-postaris, egg cocoons of the invasive alien Rapana venosa, the gastropod Bittium reticulatum and the serpulid polychaete Spirobranchus polytrema.MarIAS Project (Invasive Alien Species Threats at Key Marine Biodiversity Areas Project); Global Environment Facility (GEF)This study was supported by the MarIAS Project (Invasive Alien Species Threats at Key Marine Biodiversity Areas Project), which is being implemented by Directorate General for Nature Conservation and National Parks under the Ministry of Agriculture and Forestry and UNDP with the financial support of Global Environment Facility (GEF).

Checklist of Cnidaria and Ctenophora from the coasts of Turkey
WOS: 000344879100002This paper presents the actual status of species diversity of the phyla Cnidaria and Ctenophora along the Turkish coasts of the Black Sea, the Sea of Marmara, the Aegean Sea, and the Levantine Sea. A total of 195 cnidarian species belonging to 5 classes (Hydrozoa, Cubozoa, Scyphozoa, Staurozoa, and Anthozoa) have been determined in these regions. Eight anthozoan species (Arachnanthus oligopodus, Bunodactis rubripunctata, Bunodeopsis strumosa, Corynactis viridis, Halcampoides purpureus, Sagartiogeton lacerates, Sagartiogeton undatus, and Pachycerianthus multiplicatus) are reported for the first time as elements of the Turkish marine fauna in the present study. The highest number of cnidarian species (121 species) was reported from the Aegean Sea, while the lowest (17 species) was reported from the Black Sea. The hot spot areas for cnidarian diversity are the Prince Islands, Istanbul Strait, Izmir Bay, and Datca Peninsula, where relatively intensive scientific efforts have been carried out. Regarding ctenophores, 7 species are distributed along the Turkish coasts, 5 of which were reported from the Black Sea. A total of 16 alien cnidarian and 2 ctenophore species were determined in the regions. Two species (Sagartiogeton laceratus and Pachycerianthus multiplicatus) are new alien species for the Mediterranean Sea and could have been introduced to the northern part of the Sea of Marmara and Iskenderun Bay, areas from which these species are recorded, by ships from the North-East Atlantic.TUBITAK ProjectTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [111Y268]; Environmental Protection Agency for Special Protected Areas (Fethiye-Gocek Specially Protected Area)Some data in the present study were obtained from a TUBITAK Project (111Y268) and the project was funded by the Environmental Protection Agency for Special Protected Areas (Fethiye-Gocek Specially Protected Area)
The expanded population of Amphistegina lobifera at Üç Adalar and Beş Adalar (Antalya, Turkey)
A NEW RECORD FOR THE MARINE ALGAL FLORA OF TURKEY: TITANODERMA TROCHANTER (BORY DE SAINT-VINCENT) BENHISSOUNE, BOUDOURESQUE, PERRET-BOUDOURESQUE AND VERLAQUE, 2002 (RHODOPHYTA, CORALLINALES, CORALLINACEAE)
The coralline alga, Titanoderma trochanter, was recorded for the first time in Turkey. In 2009, thalli were observed in the wave-exposed lower eulittoral rock settings at depths of 0.1-0.5 m on the coasts of Fethiye Bay (south-eastern Aegean Sea) and Kas (Antalya, Levantine Sea). It often covered approximately 30-40% of rocky substrata where it was found in Fethiye Bay. The vegetative structure as well as habitat and the distribution of this species are described
First report of Caulerpa taxifolia (Bryopsidales, Chlorophyta) on the Levantine coast (Turkey, eastern Mediterranean)
Since its first accidental introduction into the Mediterranean Sea, Caulerpa taxifolia (Vahl) C. Agardh has spread to six Mediterranean countries and has become a major ecological problem. On the basis of morphological and molecular studies (nuclear ribosomal internal transcribed spacer (ITS)), we report for the first time C. tax fblia on the Levantine coast (Gulf of Iskenderun, SE Turkey). Phylogenetic analysis revealed that the Iskenderun isolate differs from the invasive aquarium strain first observed in Monaco, and falls in another SW Pacific clade (NE Australia, New Caledonia). The introduction in Turkey by shipping (ballast waters or anchor gears of oil tankers) is possible because C. taxifolia was found in the Gulf of Iskenderun, which is a major Eastern Mediterranean petrochemical region. On the other hand, C. taxifolia strains are available in aquarium shops in Turkey, suggesting aquarium dumping as another possible cause. As far as the intense maritime traffic of the region is concerned, further dispersals of this exotic C. taxifolia strain in the Mediterranean Sea are to be expected. (c) 2007 Elsevier Ltd.
