Rok: 2004 AnotaceThe Mediterranean, Black, and Caspian Seas represent three fragments of the former Tethys Sea, and are thus of great interest to understanding the evolution of the entire region where Eurasia, Africa and the Arabian Peninsula meet. Fishing activity and maritime traffic through the Dardanelles and Bosporus, and via the Lenin Canal to the Caspian Sea, have greatly intensified. Moreover, all major European rivers are now linked by canals, meaning that ships can navigate from the mouth of the Volga to the Baltic, from the Danube to the Rhine, and from there to all other major European Rivers. Such an anastomosed system not only allows ships to pass between basins: biota follow in their wake, and thus the Black Sea and Caspian fauna and flora, long sequestered in their closed basins.
