Abstract
In this study we report the first finding of the red alga Acanthosiphonia echinata in the Mediterranean Sea. Specimens were identified using the DNA barcoding method and, in particular, the plastidial rbcL and the mitochondrial COI-5P markers. This species has been considered to be restricted to the western Atlantic and was reported in blooms from North Carolina to South Carolina. In 2015 the introduction of this species in Southeast Asia (Indonesia) was reported. Probably this taxon was introduced in the Mediterranean Sea from Indonesian populations associated with seaweed farming activities or hull fouling, via the western Atlantic-Mediterranean-Indonesia ship route.
About the authors
Marion A. Wolf is a postdoctoral researcher at the Department of Environmental Sciences, Informatics and Statistics, Ca’ Foscari University of Venice (Italy). She obtained her PhD in Evolutionary Biology in 2012 at the Department of Biology, University of Padova (Italy). Her research focuses on the study of macroalgal systematics and biodiversity in the Mediterranean Sea.
Alessandro Buosi is a technician at the Department of Environmental Sciences, Informatics and Statistics, Ca’ Foscari University of Venice (Italy), where he obtained his PhD in Environmental Science in 2015. His research focuses on the study of aquatic macrophyte ecology in the Mediterranean Sea.
Adriano Sfriso is full professor of Ecology at the University Ca’ Foscari Venice. His research concerns Applied Ecology with particular attention to the primary producers, the eutrophication and pollution of the transitional environments. He has set up an environmental quality index (macrophyte quality index) to assess the ecological status of the transitional environments of the Mediterranean eco-region based on the study of macrophyte associations (European Water Framework Directive 2000/60/EC).
