Abstract To solve a long-lasting controversy on the timing and mechanism of generation of the western Anatolian graben system, new data have been collected from a mapping project in western Anatolia, which reveal that initially north-south trending graben basins were formed under an east-west extensional regime during…

The Black Sea ecosystem suffered catastrophically during the 1980s and early 1990s from the effects of eutrophication and the arrival of an invasive species, the ctenophore Mnemiopsis. However, this ecosystem is now on the road to recovery due to a decline in nutrient input from rivers such as the Danube that feed int…

The Pontocaspian (Black Sea - Caspian Sea) region has a very dynamic history of basin development and biotic evolution. The region is the remnant of a once vast Paratethys Sea. It contains some of the best Eurasian geological records of tectonic, climatic and paleoenvironmental change. The Pliocene-Quaternary co-evolu…

Abstract Pamukkale (Cotton Castle), in the west Anatolian sector of the Aegean extensional province, is so named because snow white travertines are accumulating there. Travertine deposition at Pamukkale, one of Turkey's most important tourist destinations, has been in progress for at least the last 400 000 years, and…

The mechanisms governing the unprecedented 1989–90 anchovy–Mnemiopsis shift event in the Black Sea were evaluated with a coupled model of bioenergetic-based anchovy population dynamics and lower trophic food web structure. Simulations showed that a combination of direct and density-dependent effects of overfishing, eu…
