Community Metabolism in Great Lakes Coastal Wetlands: Development of an Index of Susceptibility

A growing body of evidence suggests that community metabolism (the   total and relative rates of primary production and respiration)   contributes substantially to the structure of fish and invertebrate   communities in Great Lakes coastal wetlands.  Community metabolism   in coastal wetlands is affected by many natural (i.e., wind and wave   energy, pelagic mixing, basin morphology) and anthropogenic factors   (i.e., nutrient loading, hydrologic manipulation).  Therefore, fish   and invertebrate communities in some coastal wetlands may be more   susceptible to anthropogenic disturbances than others based on   geomorphology and orientation to prevailing wind and waves.  The   objective of this project is to quantify community metabolism in   Great Lakes coastal wetlands and describe its relationship with both   natural hydrologic variables and anthropogenic disturbance   variables. This information will be used to generate an index for   determining whether a wetland is particularly susceptible to   anthropogenic disturbances based on natural geomorphology.  Community metabolism will be measured along gradients of wave energy   and hydrologic mixing and anthropogenic disturbance.  Community   metabolism will be measured in three compartments including the   sediment, epibenthos, and the water column.  Characteristics which   make certain wetlands particularly vulnerable to disturbance (i.e.,   shallow, east-facing, limited fetch) will then be identified and   combined into an index of coastal wetland susceptibility.
