Three new alien species have been recorded in the Italian waters: the red alga Osmundea oederi, the calcareous sponge Paraleucilla magna (which represents the first alien sponge recorded in the Mediterranean), the cephalaspidean mollusc Haminoea cyanomarginata. Studies on the biology and ecology of species that had been introduced previously have continued, with special emphasis on the invading algae (Caulerpa racemosa var. cylindracea) and the toxic microalgae (Alexandrium, Coolia and Ostreopsis) Range expansion of some thermophilic species is reported together with new records in neighboring Countries, among which the presence of Styela clava in the Lagoon of Thau is of special concern.

Abstract
Three new alien species have been recorded in the Italian waters: the red alga Osmundea oederi, the calcareous sponge Paraleucilla magna (which represents the first alien sponge recorded in the Mediterranean), the cephalaspidean mollusc Haminoea cyanomarginata. Studies on the biology and ecology of species that had been introduced previously have continued, with special emphasis on the invading algae (Caulerpa racemosa var. cylindracea) and the toxic microalgae (Alexandrium, Coolia and Ostreopsis) Range expansion of some thermophilic species is reported together with new records in neighboring Countries, among which the presence of Styela clava in the Lagoon of Thau is of special concern.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
