Master's Theses
Salt marshes are important, highly productive ecosystems that provide many ecological benefits, including shoreline protection. Salt marshes were long believed to be driven by bottom up forces, however, recent research has suggested that top down influences may impact the foundation species Spartina alterniflora, and consequently marsh structure. This study looked at patterns of Spartina alterniflora dieback along creek bank areas and assessed Sesarma reticulatum abundance spatially throughout the marsh to improve understanding as to whether Sesarma may be influencing the dieback phenomenon. Dieback was occurring in all three salt marshes studied, at two of those marsh sites the rate of …
