| Definition | Sheltered and very sheltered lower eulittoral mixed substrata often supports Fucus serratus. This biotope differs from Fser.Fser in having a less dense canopy and reduced richness of epifaunal species, being subject to increased siltation and disturbance of unstable substrata. Amongst the pebbles and cobbles can be found shore crabs Carcinus maenas, numerous gastropods (Littorina littorea, Littorina obtusata/mariae and Gibbula cineraria) and large mussels Mytilus edulis, commonly occurring in clumps. Sediment in the spaces between the loose substrata may support infauna such as the lugworm Arenicola marina and the sand-mason Lanice conchilega. FserX occurs below mid eulittoral fucoids (FvesX or AscX) on mixed substrata shores, or on sediment shores where mixed substrata occurs in discrete patches on the lower shore. One variant of this biotope is described: tide-swept F. serratus (FserX.T). | |
