Mean species number per sample (+SD, n = 12) in epibenthic mussel beds (beds of M. edulis in Germany and mixed beds of P. purpuratus and M. chilensis in Chile) and endobenthic mussel beds (beds of M. senhousia in South Korea and X. inconstans in Australia) in comparison to bare tidal flats without mussel aggregations
