Ebook "Strategies of distinction: The construction of the ethnic communities, 300-800" discusses the process of construction of ethnic identities. What did names, law, language, costume, burial rites, rhetoric, culture, royal representation or ideology mean, and to whom? This is the question that is common to the papers assembled here. Even though they span several centuries, and a geographic area from the Iberian peninsula to the Black Sea steppes, they all deal with the ways how ethnic distinction became a political factor in the post-Roman world.

Ebook "Regional satellite oceanography" addresses the whole range of problems relating to the application of satellite technology to studies of regional seas and sea phenomona - the Gulf Stream, the Kuroshia Current - and coastal zones. It argues that to emphasize global applications is to fail to take into account fundamental idiosyncracies specific to the regional perspective. In addition, it describes implementation techniques - data gathering; in situ data assurance, algorithms for parameter retrieval; data storage; and data output.

Cherry laurel is one of the most important cherry species and naturally grown in Black sea region in Turkey. Its fruits are sold at high price in local markets in northern parts of Turkey. Cherry laurel fruits are very perishable with a limited shelf life due to a high metabolic activity and susceptibility to mechanical damage and microbial attack. The effect of edible coatings (EC) based on caseinat, Semperfresh and lecithin on the fruit quality, bioactive content and antioxidant activity of cherry laurel fruits stored at 4 ± 1 °C for 15 days was evaluated.

In study "Comparative study of phenolic compounds in olive oils from different geographic regions", the effect of cultivar, harvest year, and the geographic regions (Mediterranean, Aegean, Southeastern Anatolia, Marmara, and the Black Sea) on phenolic compounds of virgin olive oils were investigated. Tyrosol was the major phenolic compound in the Mediterranean, Southeastern, and Black Sea regions.

A belt of Upper Eocene–Lower Oligocene marine sedimentary rocks extends from Kıyıköy on the Black Sea coast to Pınarhisar in the Thrace Basin, suggesting a marine connection between the Black Sea and the Thrace Basin during this period. The Cenozoic succession of this marine corridor was studied in the vicinity of Kıyıköy along two measured stratigraphic sections.

The Oligocene Ruslar Formation, an equivalent of the Maykop Suite, is a potential hydrocarbon source rock in the western Black Sea Basin. In contrast to the offshore areas, the depositional environment and hydrocarbon source rock potential of onshore Bulgaria sediments are largely unknown. Hence, a 14-m-thick section of the Ruslar Formation, exposed near Karadere (Black Cape) along the Black Sea coast, provides an excellent opportunity to study the upper part of the Ruslar Formation.

Lithostratigraphic units (formation, strata, and beds) and regional stages of the Oligocene-lower Miocene succession of southern Ukraine are described based on the results of comprehensive lithological and paleontological data analysis. The historical perspective on the stratigraphical investigations of the Maikop Group in the Crimean and Kerch Peninsulas and their equivalents in the broader Peri-Black Sea Region were also integrated in this overview.

The Late Pleistocene-Holocene evolution of the Adapazarı Basin was investigated using the stratigraphy, geometry, and absoluteluminescence dating of the 4-step fluvial terrace staircases of the Sakarya River. The results revealed that the fluvial cycle was primarily related to relative sea level changes of the Black Sea. The initiation of deposition and the abandonment ages of the terraces indicated relative high stands during marine isotope stage (MIS) 5a (~84–72 ka), 3 (40–30 ka), and 1 (9 ka-recent).

The Payas region bauxite deposits occur as a sandwiched layer that is a few kilometers long and an average of 10 m thick between the lower and upper Cretaceous carbonates of the Arabian Platform. The bauxites occur as 2 types, comprising blanket and pocket, are chemically and texturally homogeneous, and have a thrust structure with ophiolitic mélange formations. The bauxite varies in color, from reddish-brown to grayish-green to black, and has a massive, patchy, and very rare oolitic-pisolitic texture.

Analysis of ca. 1400 km of multichannel seismic data indicate that the distal part of the Sakarya Canyon within the continental rise is an unstable region with sediment erosion. Fourteen buried debris flows (DB1–DB14), in the stacked form within Plio–Quaternary sediments between 1400 and 1950 m water depth, were observed in the surveyed area. Their run-out distances range from 3.8 to 24.4 km. The largest debris flow DB10 affects ca. 225 km2 surficial area transporting ca. 15 km3 of sediment in S to N direction.

The timing of the deposition of the well-preserved Quaternary marine terraces in the coastal region of northeastern Turkey are crucial in understanding the Quaternary tectonics of the Pontides. The chronology of raised marine terraces between Trabzon and Rize has remained unrevealed because of chronologic limitations. This study aims to establish chronology for the terrace deposits by applying optically stimulated luminescence (OSL) dating methods using single aliquot regenerative dose (SAR) techniques on quartz grains extracted from marine terraces.

idae species found in the Turkish waters have not been documented. Flyingfish eggs were randomly obtained on 16 July 2016 on the coast of Gümüldür, at a depth of approximately 1 m from a sandy bottom. Samples were fixed in a 4% buffered formaldehyde solution. The eggs were described and illustrated. The diameters of spherical fish eggs were between 1.75 mm and 2.05 mm. They have bipolar filaments: a single filament on one pole and 28–33 filaments on the other pole.

During 2013–2016 in Sevastopol Bay, seasonal and interannual dynamics of the population density, age and sex composition, fecundity, and mortality of males and females of O. davisae were studied. A maximum population number (up to 554 ind × 103 m–3) was registered at the end of summer–end of autumn. In this period, the nauplii and early copepodite stages constituted up to 95% of the O. davisae population. During 1–2.5 cold winter–spring months, the population consisted only of females, who were not numerous.

The heterotrophic dinoflagellate Noctiluca scintillans was a major component of plankton samples in the Sinop region, presenting its highest values in April 2005. Mesozooplankton abundance values showed significant differences (except 2007–2009 and 2008–2009) during the 5-year sampling period. Since the middle of 2006, an increase in abundance, biomass, and biodiversity of mesozooplankton has been detected. Many mesozooplanktonic species/groups showed seasonality in the study (especially Cladocera species). This seasonality was determined to be based on temperature changes.

Hydroacoustic surveys are one of the prime methods to assess the commercially top-ranked small pelagic stocks. The method relies on acoustic scattering from a fish, which is largely controlled by the size and morphology of the swimbladder. In this study, the changes in the size of the European anchovy swimbladder sampled in the Black Sea were investigated. Ventral cross-sectional area (by photographing the ventrally dissected fish) and volume (by dorsal and lateral X-raying) of the swimbladders were estimated.

The swimming ground speed and swimming depths of beluga sturgeon (Huso huso) and stellate sturgeon (Acipenser stellatus) were investigated using ultrasonic telemetry between 2011 and 2017 in the Lower Danube River (river kilometer (rkm) 0 Sulina–rkm 1075 Baziaș). Acoustic telemetry receivers VR2W and V16TP tags (Vemco, Canada) were used to collect data about sturgeon migration behavior in the Lower Danube River between the Black Sea and the Iron Gate II dam.

The violet carpenter bee is a species which can chiefly be found around the Mediterranean Sea and the Black Sea. This bee species has rarely been found in Poland, which is the northernmost area of its occurrence. Between 1868 and 1935, the Xylocopa violacea (Linnaeus, 1758) was observed at only 8 locations in Poland. There were then no reports of the occurrence of this bee species in Poland for 70 years. The species was noted again in 2005; between 2005 and 2017, it was noted at 20 locations.
