Alien Biodiversity Biogeography Caulerpa C. peltata C. racemosa C. racemosa var. cylindracea C. taxifolia Invasive New Caledonia Seaweed tufA Molecular characterization (plastid-encoded tufA gene) of New Caledonian members of the Caulerpa racemosa-Caulerpa peltata complex identified five lineages, each possibly harboring multiple species-level entities. On a global scale, the complex encompassed six lineages, two of which were pantropical and the remainder seemingly were restricted to the Judo-Pacific basin. Caulerpa racemosa var. cylindracea, a fast-spreading introduced taxon in the Mediterranean Sea and the Canary Islands, was previously thought to be restricted to southwestern Australia; it was newly reported here for New Caledonia and several northern Australian locations, including the Great Barrier Reef. 2013 text https://www.documentation.ird.fr/hor/fdi:010060696 fdi:010060696 Sauvage T., Payri Claude, Draisma S.G.A., van Reine W.F.P., Verbruggen H., Belton G.S., Gurgel C.F.D., Gabriel D., Sherwood A.R., Fredericq S..
