Concept: [Polydora ciliata] and [Corophium volutator] in variable salinity infralittoral firm mud or clay in the eunishabitats vocabulary

Concept URI http://eunis.eea.europa.eu/eunishabitats/A5.321
Preferred label [Polydora ciliata] and [Corophium volutator] in variable salinity infralittoral firm mud or clay
Definition Variable salinity clay and firm mud characterised by a turf of the polychaete [Polydora ciliata] along with the amphipod [Corophium volutator]. Other important taxa include the polychaetes [Pygospio elegans], [Hediste diversicolor, Streblospio shrubsolii] and the oligochaete [Tubificoides benedii]. [P. ciliata] also occurs in high densities elsewhere (see MCR.Pol) and may be a specific feature of the Humber Estuary in these conditions. This biotope occurs only in very firm mud and clay and possibly submerged relict saltmarsh with a high detrital content. It is characterised, and can be separated from other biotopes, by a combination of the sediment characteristics and the very high density of [Polydora ciliata]. In some areas, such as the Humber estuary, cyclical behaviour with regard its characteristic taxa has been reported with either [P. ciliata] or [C. volutator] increasing in dominance at the expense of the other (Gameson 1982). It is possible that changes in water quality or the sediment regime may be responsible for this.
