Identification and description of macrobenthic communities in the calvert cliffs region of the Chesapeake Bay

摘要: The macrobenthos (>1.0 mm) in the Calvert Cliffs region of Chesapeake Bay was sampled over a three year period (1971–1974). Four distinct communities (shell, 3 m sand, 6 muddy-sand, 9 mud) were identified and described using single-linkage cluster discriminant analyses. Substrate characteristics major environmental factor controlling spatial distribution macrobenthic within study area, habitat relatively homogeneous throughout region. structure muddy-sand community variously resembled sand or 9-m mud depending upon season year.
