Communities of Marmara infralittoral estuarine mud

Description (English)

This habitat occurs mainly in sheltered inlets in or adjacent to estuaries, where wave exposure is low enough to allow fine sediments to settle. It is characterized by a variable salinity range from brackish to fully marine conditions. In all cases, the resident populations comprise a small number of species that are strongly dominant in number and weight. These are species that are able to withstand violent variations in environmental conditions, among which salinity is only one example. Sudden influxes of salt water create recurrent disturbances that sometimes cause populations to disappear. Often, especially in shallower areas, beds ofCymodocea nodosaare present. Characteristic species: Tubificoidesspp, Capitella capitata, Ficopomatus enigmaticus, Heterochaeta costata, Alitta succinea, Spio decoratus, Aphelochaeta marioni, Hydrobia acuta, Spisula subtruncata, Corophium orientale, Gammarus aequicauda, Carcinus aestuarii, Thalassodrilides gurwitschi.
