"The composition and production of sublittoral macrobenthic invertebrate communities from three regions along the Atlantic coast of Nova Scotia were examined. The Pubnico region was characterized by extensive forests of macrophytic algae, while Ingomar and Dover were dominated by epilithic coralline algae. Coralline dominated habitats have a much higher invertebrate biomass than macrophyte forest habitats, mainly due to an abundance of Strongylocentrotus roebachiensis and Modiolus modiolus in coralline communities. Invertebrate production was similar from habitat to habitat. Faunal distribution patterns were related to environmental and algal conditions. The degree of macrophyte cover and exposure to waves and currents were the most significant factors affecting distribution. The food resources for the American lobster Homarus americanus were examined and prey preferences determined. Significant differences were found from region to region in some of the typpes of prey species most highly selected for. Crustaceans of all types were selected for in all regions while S. droebachiensis was never selected for. Production of preferred lobster prey was highest in macrophyte forests." (Abstract).
