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 ...

Seasonality of caulerpenyne content in native Caulerpa prolifera and invasive C. taxifolia and C. racemosa var. cylindracea in the western Mediterranean Sea
Fronds had higher mean caulerpenyne concentration than stolons in Caulerpa prolifera, C. taxifolia and C. racemosa. C. prolifera had higher mean caulerpenyne content w7.29"0.64% caulerpenyne/frond dry weight (DW)x than C. taxifolia (5.47"0.32% caulerpenyne/frond DW) and C. racemosa (0.43"0.07% caulerpenyne/frond DW). C. prolifera had reduced content from May to October in fronds, with no clear ...
متن کاملOn the identity and origin of the Mediterranean invasive Caulerpa racemosa (Caulerpales, Chlorophyta)
Recent morphological and genetic studies on the Caulerpa racemosa (Forsskål) J. Agardh complex have demonstrated that three taxa occur in the Mediterranean Sea. One of them, the ‘invasive variety’, provisionally regarded as close to C. racemosa var. occidentalis J. Agardh, is currently spreading spectacularly throughout the Mediterranean. On the basis of new morphological and molecular studies ...
متن کاملThe Caulerpa racemosa invasion: a critical review.
Caulerpa racemosa var. cylindracea is a marine Chlorophyta introduced into the Mediterranean Sea from south-western Australia. Since 1990, it has been invading the Mediterranean Sea and the Canary Islands, raising ecological problems. Although this invasion event can be considered as one of the most serious in the history of species introduced into the Mediterranean Sea, C. racemosa has not tri...
