Contents Notes
Benthic macrofauna are an important component of estuarine ecosystems. These organisms are a food source for higher trophic levels including fishes and crabs and birds. Benthic macrofauna affect both the physical and chemical properties of the sediment and the overlying water column, influence nutrient cycling, and are capable of directly controlling phytoplankton biomass in the water column. Because of these characteristics, monitoring of the benthos provides important information for making management decisions in marine systems. Also, the relatively long life span and sedentary nature of these organisms make them good indicators of water quality and the effects of man-made disturbances on aquatic systems. The objective of this study was to develop analytical tools that are capable of classifying regions in Chesapeake Bay identified as having degraded benthic communities into categories distinguished by the type of stress experienced by those communities.
