Concept: Seaweeds in sediment-floored eulittoral rockpools in the eunishabitats vocabulary

Concept URI http://eunis.eea.europa.eu/eunishabitats/A1.413
Preferred label Seaweeds in sediment-floored eulittoral rockpools
Definition Rockpools with sediment (mud, sand, gravel) floors support distinct communities of scour-tolerant seaweeds. Deep pools with sediment are similar to FK, and are typically dominated by fucoids and kelp ([Fucus serratus], [Laminaria digitata], [Laminaria saccharina] and [Saccorhiza polyschides]). Areas of hard substrata near to the interface with the sediment are, however, characterised by a range of sand-tolerant seaweeds such as [Furcellaria lumbricalis], [Polyides rotundus], [Ahnfeltia plicata] and [Rhodochorton purpureum] (compare with FK). [Chorda filum] may occur attached to pebbles and shells embedded within the sediment while the top shell [Gibbula cineraria] can be found underneath or among the pebbles. In pools with large areas of sand, infaunal species such as [Arenicola marina] and [Lanice conchilega] often occur. The seagrass [Zostera] spp. may occur in some pools where stable sand is present. Shallow rockpools with cobble and pebble floors, often with an underlying layer of sediment, support red algal tufts consisting of coralline crust, [Corallina officinalis], [Chondrus crispus], [Mastocarpus stellatus] mixed with [Ceramium] spp. and the green seaweeds [Cladophora] spp. and [Enteromorpha intestinalis]. The long list of characterising species is partly due to low similarity between the available records and care should be taken not to interpret this solely as a very high species richness. Situation: Rockpools throughout the eulittoral zone in bedrock on exposed to sheltered shores. Temporal variation: Seasonal fluctuations in the abundance of ephemeral seaweeds will occur.
