The salt marsh periwinkle, Littorina irrorata, exhibits a spatial refuge from predation by climbing the stems of Spartina alterniflora in order to avoid benthic predators. As a result, periwinkle densities pile up and over time increase along the edges of the mudflats, forming a “snail front.” In this study, researchers tracked changes in cordgrass and snail densities after a lengthy period of drought in order to determine whether periwinkle snail fronts expand mudflats and contribute to salt marsh die-offs.
