Threat to macroalgal diversity: effects of the introduced green alga Caulerpa racemosa in the Mediterranean
Caulerpa racemosa is a tropical green alga introduced into the Mediterranean probably as an immigrant from the Red Sea. This study evaluated the modifications caused by C. racemosa invasion on the structure of the benthic macroalgal community near Leghorn (northwestern Mediterranean). To achieve this objective, we studied invasion by C. racemosa of algal assemblages on 2 different substrata by ...
