Neomysis integer and Gammarus spp. in low salinity infralittoral mobile sand
|Within Vocab||Marine Habitat Classification for Britain and Ireland Version 97.06|
|Definition||Upper estuary mobile sands with very low fluctuating salinity characterised by the mysid shrimp Neomysis integer (see Arndt 1991) and amphipods of the genus Gammarus spp. The harsh physicochemical regime imposed by such environmental conditions in the upper estuary leads to a relatively impoverished community but high densities of the mobile, salinity-tolerant, crustaceans can occur. The biotope is found in the transitional zone between freshwater and brackish environments, relying on the decreased freshwater input during the summer for penetration of the brackish species up-stream. As such this biotope may also contain elements of freshwater communities. It may be found in conjunction with IMU.LimTtub, although it lacks appreciable numbers of oligochaetes. The biotope occurs in a similar habitat to IGS.MobRS although it is more affected by lower salinity.|
