The inherent low species biodiversity of the Black Sea (roughly one-third of the Eastern Mediterranean Sea) is a sign of ineffective bio-invasion process of Mediterranean species. This phenomenon is explained on the basis of a hypothesis that strong physical gradients and some accompanying physiological limitations along the colonization route of Turkish Straits System (TSS) make Mediterranean ...

T he Black Sea, earth’s largest anoxic water body, serves as a model system for studies of marine chemistry and biology. The article by Lam et al. (1) in this issue of PNAS describes a new approach to assessing the activity of Black Sea nitrifying bacteria and archaea that are globally important in nitrogen metabolism. The Black Sea was formed after the retreat of the glaciers in the most recen...

In this study, the effect of cultivar, harvest year, and geographic regions (Mediterranean, Aegean, Southeastern Anatolia, Marmara, Black Sea) on phenolic compounds virgin olive oils were investigated. Tyrosol was major compound in Mediterranean, Southeastern, Sea regions. Hydroxytyrosol showed highest value (2.07 mg/kg) Anatolia region lowest (0.75 Marmara region. Among acids, vanillic acid ha...

BACKGROUND In the aftermath of earthquakes, the cumulative incidence of crush-induced acute kidney injury (AKI) is difficult to predict. Insight into factors determining this risk is indispensable to allow adequate logistical planning, which is a prerogative for success in disaster management. METHODS Data of 88 crush-related AKI patients in the aftermath of the Kashmir earthquake were collec...

In this Collective Article on alien and cryptogenic diversity in the Mediterranean Sea we report a total of 19 species belonging to nine Phyla coming from countries. Several these records concern fish species, particular interest are first of: Terapon puta for Italian waters; Pteragopus trispilus Malta; Plotosus lineatus Cyprus; northernmost record Lagocephalus sceleratus. The was also reported...

The coccolithophorid Ochrosphaera neapolitana was reported for the first time from samples obtained during a large-scale mucilage event in Sea of Marmara May 2022 previous study. We also found this species our about year ago (i.e., June 2021). In study, O. further isolated and produced laboratory as monoculture investigations using electron microscopy molecular methods. identified small sub-uni...

We calculate the probability of strong shaking in Istanbul—an urban center of 10 million people—from the description of earthquakes on the North Anatolian fault system in the Marmara Sea during the past 500 years, and test the resulting catalog against the frequency of damage in Istanbul during the preceding millennium. Departing from current practice, we include the time-dependent effect of st...
