Whether or not C. taxifolia has been present for a longer period of time in the marine flora, either as a cryptic endemic species or as the result of one or more introductions, represents an additional hypothesis that will require identification of biogeographic populations from throughout the world, as well as a population‐level study of the Mediterranean region.

Phylogenetic analyses of Caulerpa taxifolia (Chlorophyta) and of its associated bacterial microflora provide clues to the origin of the Mediterranean introduction. Caulerpa taxifolia was officially eradicated from southern California in 2006. Caulerpa veravalensis is similar to C. taxifolia but differs in the shape of the stolon. The two species are thus not conspecific.

In order to establish the taxonomic identities of these taxa, individuals from five populations of C. taxifolia and four populations of C. mexicana were collected from within and outside of the Mediterranean. The Journal of Phycology was founded in 1965 by the Phycological Society of America.

Caulerpa is native to tropical regions throughout the world, including tropical and subtropical parts of Australia, with its southern natural limit at Moreton Bay in Queensland. Strain XY-214, and d-Xylulose Production from β-1,3-Xylan. | We collected a lot of caulerpa samples along the coasts of North Africa, of Sardinia and Spain. The aquarium strain of Caulerpa taxifolia is an extremely invasive seaweed that has infested tens of thousands of acres in the Mediterranean Sea. taxifolia–mexicana intermediates), a PCR diagnostic amplification can easily be performed because the ITS1 in C. taxifolia is 36 nucleotides shorter than the ITS1 in C. mexicana. Selective breeding under exposure to both chemicals and ultra-violet light produced even hardier Caulerpa strains. Caulerpa taxifolia is a marine macro-algae that is native to tropical waters of the Indian, Pacific and Atlantic oceans. . Separation is maintained whether the analyses are based on just the more conserved 18S data or just the fast‐ evolving spacers. DEFINING TAXON BOUNDARIES IN MEMBERS OF THE MORPHOLOGICALLY AND GENETICALLY PLASTIC GENES CAULERPA (CAULERPALES, CHLOROPHYTA). Branches, feather-like, flattened, and upright, 3 - 10 cm high, rising from a creeping stolon (runner), 1 - 2 mm in diameter, anchored by rhizoids to the substrate. It is widely used ornamentally in aquariums, because it is considered attractive and neat in arrangement, and is easy to establish and care for. In 1984, Caulerpa taxifolia (Vahl) C.

Intraspecific variation in seaweeds: The application of new tools and approaches. We evaluated whether the exotic seaweed, Caulerpa racemosa, is the primary cause of degradation (i.e., responsible for the loss of canopy‐formers and dominance by algal turfs) on Mediterranean rocky reefs, by experimentally removing the invader alone or the entire invaded assemblage. Caulerpa taxifolia is an invasive marine alga that is often referred to as "Killer Algae".
