Project Description
The relationship between ribbed mussels Geukensia demisssa and smooth cordgrass Spartina alterniflora is a classic example of a mutualism. The grass provides shade and settlement habitat for mussels, while mussels stabilize sediment surfaces and fertilize plants through deposition of feces and pseudofeces. We investigate whether the presence of ribbed mussels in restored urban marshes of Jamaica Bay and the Harlem River (New York, NY) enhances plant growth and nitrogen-removal services.
