Benthic foraminiferal assemblages from the Gulf of Edremit, Lesbos Island, Alibey and Maden islands and Dikili Bay have been investigated and various morphological abnormalities, as well as, colored tests and large sizes have been observed. Besides, abundance of alien species originating from tropical seas attracts attention. Interesting togethernesses were found between different genera and species. Significant differences were observed between the assemblages from the northwest and southeast coasts of the Gulf of Edremit. 57 genera and 97 species were identified in the samples from the northwest coast, where as only 32 genera and 48 species were found on the southeast coast. A diverse foraminifer assemblage were observed around the Ayvalik-Alibey and Maden islands, with large individual sizes, colored tests and morphological abnomalities. Abnormal togethernesses between different genera and species were also observed in this locality. Togethernesses between Peneroplis pertusus (Forskal)-Coscinaspira hemprichii Ehrenberg and Peneroplis planatus (Fichtel and Moll)- Coscinaspira hemprichii Ehrenberg are important findings in the benthic foraminiferal assemblages of Ayvalik Alibey and Maden islands. Orange and brown coloration observed on many Peneroplis pertusus (Forskal) and P. planatus (Fichtel and Moll) individuals is another important finding in this region. Besides, many individuals of Peneroplis pertusus (Forskal), P. planatus (Fichtel and Moll), Lobatula lobatula (Walker and Jacob), Cibicidella variabilis (d'Orbigny), Ammonia compacta Hofker, A. parkinsoniana (d'Orbigny), Challengerella bradyi Billman, Hottinger and Oesterle, Elphidium complanatum (d'Orbigny) and E. crispum (Linné) were found. The presence of Laevipeneroplis karreri (Wiesner), Peneroplis pertusus (Forskal) and P. planatus (Fichtel and Moll) and Sorites orbiculus Ehrenberg on the east coast of Lesbos Island indicates the presence of hotwater springs. An abnormally large Peneroplis planatus (Fichtel and Moll) individual were found. Besides, many Peneroplis pertusus (Forskal) and P. planatus (Fichtel and Moll) individuals with orange-yellow tests, like the ones in Ayvalik, were found, suggesting the presence of submarine springs with Fe content. An abnormal Peneroplis planatus (Fichtel and Moll) individual with three different apertures was found in Dikili samples. One of the apertures was typical of the species, whereas the other two have the aperture characteristics of Coscinospira hemprichii Ehrenberg. The aim of our study is to figure out the factors leading to abnormal test morphologies. It is suggested that the benthic foraminiferal assemblages found in the study area are affected by the physical environmental conditions such as, temperature and salinity, as well as the chemical factors, such as radioactivity.

The Gulf of Izmir has seen the construction of marinas at four locations; Karşıyaka, Bayraklı, İnciraltı and Urla (Çeşmealtı). Six drilling holes have been structured for each location. Morphological abnormities observed in foraminifer tests, obtained from these core drillings, and coloring encountered in both foraminifer tests and ostracod carapeces, provide evidence of natural and unnatural environmental pollution. The objectives of this study are to identify micro and macro fauna, foraminifers in particular, contained within sediments in the above-mentioned locations; to investigate the background of pollution in the Gulf Region; and to determine pollution's impact upon benthic foraminifer and ostracods. Çeşmealtı foraminifera tests did not lead to color and morphological changes. But foraminifera tests samples collected from Karşıyaka, Bayraklı and İnciraltı led them to turn black (Plate 4–6). However, concentrations of heavy metals (Ni, Cr and Mn) obtained from the sediments of Karşıyaka, Bayraklı and İnciraltı locations are higher than those obtained from the Çeşmealtı samples and high concentrations of these elements may be the cause of the color change in the samples during the foraminifera tests. In Karşıyaka and Bayraklı ostracod samples, Bosquetina carinella, Pterygocythereis jonesi, Semicytherura species; in the Çeşmealtı/Urla zone, Cyprideis torosa; in İnciraltı, Pseudopsammocythere reniformis; and in four zones, Loxoconcha and Xestoleberis species were observed in the range of relative frequency. The same analyses were done on nannoplankton but they did not lead to color and morphological changes. © 2016 Elsevier Ltd

Benthic foraminifera are single-celled organisms abundantly found in all kind of marine environments from brackish estuaries to the deep ocean basins at all latitudes. Foraminifera are covered with an organic test which accumulate in the sediment and make up a significant amount of sedimentary rock. Many species have well defined salinity and temperature preferences making them particularly useful for reconstructing ecological changes occured in the past. The fossil tests not only used for paleoenvironmental interpretition, but also for biostratigraphy and age-dating. Anthropogenic pollution or environmental factors may cuase abnormal development of the test, such as aberrant chamber shape and size, twisted or distorted chamber arrangement, multiple apertures, twin, triplet and even quadruplet forms. These abnormalities are commonly used as indicators of pollution. Many researchers have studied the recent benthic and planktic foraminifera of the Mediterranean fauna. The studies have investigated the distribution and abundance of the species, composition of the foraminiferal assemblages, ecological factors and interractions of tests with the substrate. Recent studies, mainly focused on the alien species and their ecological impact. Despite the numerous researches, there is a lack of a comprehensive illustrated guide to the Mediterranean foraminifeal fauna, except the "Mediterranean Foraminifera" (Cimerman and Langer 1991), which included samples from Adriatic and Tyrrhenian Seas, representing mostly the western Mediterranean fauna. With the presented SEM photos of 299 species in 84 plates, the aim of the present Atlas is to fill the gap and provide an updated checklist of foraminiferal fauna of the Turkish coastline, representing the majority of the Levantine Basin.

The benthic foraminiferal fauna in Pamucak Cove (NW Kuşadasi, Turkey) was investigated. A rich foraminiferal assemblage was observed around submarine springs, which were located 200 m off the coast. This foraminiferal assemblage is typical Mediterranean. However, the abundance of alien species is noteworthy. Fourteen alien foraminifera were found. Indo-pacific originated species; Quinqueloculina sp. C, Triloculina sp. A, Pyramidulina catesbyi (d'Orbigny), Brizalina simpsoni (Heron-Allen and Earland) and Amphistegina lessonii d'Orbigny were observed for the first time on the Turkish coastline. Specimens of Haddonia sp. and Cymbaloporetta plana (Cushman), abundantly observed in SW Antalya and Nodopthalmidium antillarum (Cushman), previously recorded from Iskenderun were also found in the study area, these are the first records for these species in the Aegean Sea. In addition, seven individuals of Euthymonacha polita (Chapman) were found around the springs, and this constitutes the first record of this species in the entire Mediterranean Sea. © 2010 The Author(s).

The delta plain of the Asi (Orontes) river in Hatay (Turkey) is located between two regional major tectonic zones, the Dead Sea Fault Zone from the Red Sea to Antakya and the East Anatolian Fault Zone from Karliova to Antakya. Sediment samples from five cores performed on the Asi delta plain to 15m depth were studied, and three fossil groups were identified in 5 samples. They mainly consist of 51 foraminiferal species from 42 genera; ostracod genera representing marine, brackish and fresh water environments, and Gastropoda and Bivalvia taxa.The abundance of some benthic Foraminifera in the recent sediment samples, including Euuvigerina reineri (Bedford), Siphonina tubulosa Cushman and Siphonodosaria abyssorum (Brady), which are common in the Pacific Ocean, Indian Ocean, Arabian Sea, and Red Sea is remarkable. In addition, Euuvigerina reineri (Bedford) individuals about 70ka have been collected from Mağaracik village to the north of the drilling area. The existence of these species in the Quaternary sediments indicates that the water connection via the Gulf of Aqaba on the Dead Sea Fault Zone was still open in the Pleistocene. © 2015 Elsevier Ltd and INQUA.

In this study, the fossil microfaunal composition of 28 Recent sediment samples from Lake Iznik and 19 samples from Lake Sapanca was investigated. The presence of at least ten marine ostracod and 23 foraminifer species in the sediments of Lake Iznik, and at least one marine ostracod and two foraminifer species in the sediments of Lake Sapanca confirm that these lakes must have been connected to the world ocean sometime during the late Quaternary. The most obvious former link between these lakes and the Mediterranean Sea would have been via the Marmara Sea with an eastward extension of the Gemlik and Izmit bays. The proximity of Lake Sapanca to the lower course of the Sakarya River, however, also supports earlier suggestions that there may have been a temporary connection with the Black Sea via this river valley. Whatever the case, the findings of this study clearly demonstrate that vertical tectonic movements need to be taken into account when reconstructing the late Quaternary sea-level history of this region. © 2010 Springer-Verlag.
