This book contains the papers presented at a NATO Advanced Research
Institute on "Mediterranean Marine Ecosystems", held at Heraklion-Crete,
Greece, from September 23-27, 1983. A workshop rather than a conference,
it was sponsored by the Eco-Sciences Special Programme Panel, in
cooperation with the Marine Science Panel. The third of its kind, it was
scheduled in the framework of a project on a multidisciplinary
integrated approach to the study of the Mediterranean. This Sea and the
surrounding land was not only the cradle of many civilizations but is,
up to the present time, one of the major world areas of marine traffic,
communication and exchanges, fisheries and aquacultures, inshore human
activities and --- pollu- tion. To a certain degree it constitutes a
gigantic natural labo- ratory, where the fate of threatened aquatic and
terrestrial eco- systems including the human one, is tested. The
Mediterranean Sea, with its geological history and present- day
geographic, hydrological and climatic conditions is believed to form an
ecological entity. Important exchanges and mutual influences take place
with the surrounding land area and the water masses, naturally
(Atlantic, Black Sea) or artificially (Red Sea), connected to the
Mediterranean. Therefore, a better and in-depth knowledge of the various
ecosystems, benthic, planktonic and nektonic, neritic or pelagic, in the
Western or the Eastern Basin seems to be a pre- requisite to any action
in preserving, upgrading and managing the natural resources of the area.
