Abstract

Increasing awareness of the ecological and economic problems caused by marine introductions has brought calls for the development of predictive models of their impacts on other species. We examined the effects of an introduced marine polychaete, Sabella spallanzanii (Gmelin, 1791), on the development of subtidal marine epifaunal assemblages. As an invader of hard subtidal substrata, S. spallanzanii alters the structure of the habitat by forming a canopy of filamentous feeding structures suspended above the substratum on long, slender tubes. As resident species (including S. spallanzanii) can strongly affect the recruitment of sessile taxa into these assemblages, we predicted that one of the ..
