Castanea sativa Mill. is thought to be originated from Turkey. It is an important deciduous angiosperm with edible fruits and valuable wood. It has a wide distribution from east Black sea to Marmara and Aegean Regions. Because of its wide distribution, C. sativa grows on different ecological, geological, climatic and edaphic condition and these results in different associations with different c...

Changing sea level is a major factor in the pattern of enrichment of organic carbon in marginal and epicontinental seas. Organiccarbon-rich facies accumulate preferentially during major transgressive episodes. Rising sea level promotes retention of nutrients in marginal seas through several possible mechanisms, leading to higher organic production and/or eutrophic conditions. Transgressive seas...

Rapana venosa is a predatory marine gastropod native to the coastal waters of China, Korea, and Japan. Since the 1940s, R. venosa has been transported around the globe and introduced populations now exist in the Black Sea, the Mediterranean Sea, the Adriatic and Aegean seas, off the coasts of France and The Netherlands, in Chesapeake Bay, Virginia, USA, and in the Rio de la Plata between Urugua...

Increasing anthropogenic CO2 concentration in the troposphere results ocean acidification. Albeit, food web ocean, marine animals and calcifying bioata are affected negatively. Some species might have possibility of extinction some may evolve eventually due to In this study, acidification Black Sea is analyzed based on pH observations made between 1990 2014. surface value found be decreased by ...

Presence of marine mammal nematodes in Turkey is poorly known. One bottlenose dolphin (Tursiops truncatus) and four harbour porpoises (Phocoena phocoena) stranded on the Turkish coast were examined at necropsy between 2009 and 2012. Harbour porpoise stranded from Marmara Sea were only infected by three species of lungworms (Metastrongyloidea): Stenurus minor, Halocercus invaginatus and H. tauri...

Two major ecological transitions marked the history of the Black Sea after the last Ice Age. The first was the postglacial transition from a brackish-water to a marine ecosystem dominated by porpoises and dolphins once this basin was reconnected back to the Mediterranean Sea (ca. 8,000 y B.P.). The second occurred during the past decades, when overfishing and hunting activities brought these pr...

PETROVA, D., 2008. Major bloom producing phytoplankton species in the lakes along the Bulgarian Black Sea Coast. Bulg. J. Agric. Sci.; 14: 201-208 Archive data analysis shows that during the different periods of anthropogenic impact phytoplankton production reaches pathologically high levels. Thus, phytoplankton is assumed as an indicator of marine water quality and ecological health. Its long-...
