Concept: Oligochaetes in full salinity littoral mobile sand in the eunishabitats vocabulary

Concept URI http://eunis.eea.europa.eu/eunishabitats/A2.2221
Preferred label Oligochaetes in full salinity littoral mobile sand
Definition A species-poor community of oligochaetes occurring in fully marine conditions on open shores with mobile, medium to fine, usually clean, sand. Oligochaetes, including enchytraeid oligochaetes, constitute the infaunal assemblage. On rare occasions individuals of polychaete or crustacean species may be encountered (e.g. [Nephtys] spp., [Eurydice pulchra], [Bathyporeia] spp.), though these are not characterising for the biotope and if present in any significant abundance, the area should be classed as AmSco. Situation: Where Ol.FS is situated on the mid shore, BarSh and/or BarSa may be present on the upper shore, and lower down on the shore, AmSco.Sco and AmSco.Pon may be found. Ol may also occur on the upper shore, with AmSco.Eur present on the mid shore, and Po.Pful or Po.Aten on the lower shore. Tal may be found on the upper shore where driftlines of decomposing seaweed and other debris accumulate. Temporal variation: Wave exposure may be higher on some beaches during winter than during the summer months, leading to the disappearance of infaunal species in winter. Where this happens, the biotope may change to BarSa. If conditions become more sheltered, seasonally or permanently, the sediment may become colonised by a greater range of species and the area may change to AmSco.
