L'article a comme objet de présenter un bilan de la colonisation de la Méditerranée par l'algue verte introduite Caulerpa racemosa var. cylindracea, treize années après le début de son expansion. L'algue a été signalée le long des còtes de 11 états. Elle pousse entre Oet 70 mètres de profondeur sur tous les types de substrats, aussi bien en zones polluées qu'en zones non polluées. Le linéaire de còte concernée par l'invasion de C. racemosa var. cylindracea entre l'Espagne, la France, l'Italie et la Croatie a été estimé entre 700 et 750 km fin 2003. Les aspects majeurs de l'écologie de l'espèce en Méditerranée les conséquences de son expansion sur les activités humaines en zone còtière sont également discutés.
The aim of this paper is to evaluate the colonization of the green alga Caulerpa racemosa var. cylindracea thirteen years after it was signalled in the Mediterranean Sea. The alga has been recorded along the coasts of 11 nations, developing on all kind of substrata, both in polluted and in unpolluted areas, between 0 and 70 m depth. The length of coastline affected by the invasion of C. racemosa var. cylindracea in Spain, France, Italy and Croatia ranged from 700 to 750 km at the end of 2003. The main aspects of the ecology of the species in the Mediterranean Sea and the effects of the invasion on human activities in coastal areas are also discussed

Abstract
The aim of this paper is to evaluate the colonization of the green alga Caulerpa racemosa var. cylindracea thirteen years after it was signalled in the Mediterranean Sea. The alga has been recorded along the coasts of 11 nations, developing on all kind of substrata, both in polluted and in unpolluted areas, between 0 and 70 m depth. The length of coastline affected by the invasion of C. racemosa var. cylindracea in Spain, France, Italy and Croatia ranged from 700 to 750 km at the end of 2003. The main aspects of the ecology of the species in the Mediterranean Sea and the effects of the invasion on human activities in coastal areas are also discussedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
