Relationships between density (D, ind. m−2) and diversity (ES(50) = estimated number of amphipod taxa in a subsample of 50 individuals) for different depth levels (above) and sediment types (below). Different superscript letters denote statistically significant differences between slopes of regression lines. ALL = entire depth gradient and all sediment types, respectively; VF–F very fine to fine sand, M medium sand, C–G coarse sand to gavel. For clarity, only average values per station have been plotted
