Interactions among introduced and indigenous submerged macrophytes in a Mediterranean shallow system

Abstract

In Termini Imerese H. stipulacea has been recorded inside artificial basins, characterized by a sandy bottom (0.80‐2.5 m depth). H. stipulacea in good health conditions shows a competition strategy with C. nodosa. But during winter denudations, C. racemosa var. cylindracea seems to negatively interfere with the rhizomes of H. stipulacea.
