Modiolus modiolus is a boreal species reaching its southern limit in British waters and it may be susceptible to long term increases in summer water temperatures (Holt et al., 1998). Little information on temperature tolerance in Modiolus modiolus was found, however, its upper lethal temperature is lower than that for Mytilus edulis (Bayne, 1976) by about 4 °C (Henderson, 1929; cited in Davenport & Kjrsvik, 1982). Extensive beds are most common on northern or western coasts but absent south of the Severn and Humber estuaries Modiolus modiolus beds are found in a variety of turbid and clear water environments (Holt et al., 1998).
