The full text of this article hosted at iucr.org is unavailable due to technical difficulties. A FORENSIC AND PHYLOGENETIC SURVEY OF CAULERPA SPECIES (CAULERPALES, CHLOROPHYTA) FROM THE FLORIDA COAST, LOCAL AQUARIUM SHOPS, AND E‐COMMERCE: ESTABLISHING A PROACTIVE BASELINE FOR EARLY DETECTION. 10.1663/0006-8101(2006)72[153:IMAAEP]2.0.CO;2. Branchlets oppositely attached to midrib, flattened, slightly curved upwards, tapered at both base and tip, and constricted at point of attachment. Selective breeding under exposure to both chemicals and ultra-violet light produced even hardier Caulerpa strains. The aquarium type has established non-native populations in the Mediterranean, Southern California, USA and temperate areas of Australia. Caulerpa taxifolia is a marine green alga believed to have been accidentally introduced into the Meditteranean Sea 2. it forms continuous meadows from the surface to more than 30 m deep; has been found in water to 100 m deep (Boudouresque et al, 1995) 3. meadows of Caulerpa taxifolia in the Mediterranean can attain exceptional densities, while in its native tropical seas the plant is usually isolated (Meinesz and Hesse, 1991) 4… Molecular approaches to the study of invasive seaweeds. Caulerpa taxifolia is an invasive marine alga that is widely used as a decorative plant in aquaria. The mentioned algae, due to intentional or unintentional introduction into the sea, brought by ballast waters, attached to vessel's hull or anchors, by fishing nets, are considered. C. sertularioides is more delicate and t… Caulerpa taxifolia has not been reported in earlier marine floras of the Mediterranean, and its sudden appearance has suggested that it may be a recent introduction. 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. In 1984, Caulerpa taxifolia (Vahl) C. Agardh was reported along the coast of Monaco. This invasive weed was discovered in southern California and New South Wales, Australia in 2000. The non-invasive form of Caulerpa taxifolia is native to the Caribbean, Indo-Pacific and the Red Sea. www.yachtagent.me. to be one of the greatest threats to the biodiversity of the sea. When it eventually found its way into the Mediterranean, widespread concern developed that the algae threatened to alter the entire ecosystem by crowding out native seaweed while being inedible to animals. For specimens of uncertain identity (i.e. SPREAD OF CAULERPA TAXIFOLIA VAR. Using genetic techniques to investigate the sources of the invasive alga Caulerpa taxifolia in three new locations in Australia. Mediterranean clone of caulerpa, plants - Photo by Rachel Woodfield; Merkel & Associates, Inc. Scientific Name: Caulerpa taxifolia (Vahl) C. Agandh (ITIS; name is accepted but unverified) Common Name: Caulerpa, Mediterranean clone; Killer algae. | We collected a lot of caulerpa samples along the coasts of North Africa, of Sardinia and Spain. Killer Alga, Caulerpa taxifolia The Situation: Caulerpa taxifolia is an invasive alga that is causing serious environmental problems in the Mediterranean Sea. Strain XY-214, and d-Xylulose Production from β-1,3-Xylan. 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. Methods for identifying and tracking seaweed invasions. Known as the "Tumor of the Sea," Caulerpa taxifolia is a fluorescent green macroalga, built of crawling trees and leaves from 5 to 65 cm in length. Described for the first time in Australia, the Caulerpa racemosa (Forsskål) J.Agardh, 1873 is a green marine alga (Chlorophyta) belonging to the family of the Caulerpaceae, like the well known Caulerpa prolifera of the Mediterranean or the infamous Caulerpa taxifolia native to Australia, Central America and the African coasts.. Tax and Duty Free Diesel, Clearance Procedures, Berth Booking, Yacht Supplying, Yacht Registration and Insurance, Technical Support and Servicing, Transfers of Crew and Passengers for the marinas of Bar, Budva, Kotor and Porto Montenegro - Tivat, as well as Ports of Bar and Kotor. One hypothesis maintains that the alga was introduced accidentally into the sea at Monaco, where it has been used as a decorative alga in aquaria. Taxonomy of Marine Macroalgae Used as Sources of Bioactive Compounds. and you may need to create a new Wiley Online Library account.

Agardh (Caulerpales, Chlorophyta) in the Adriatic Sea The first report of Caulerpa taxifolia in the Mediterranean is from 1984. DISTICHOPHYLLA IN THE WESTERN AND NORTHERN MEDITERRANEAN BASIN. It was first identified outside its natural range near Monaco in the Mediterranean Sea in 1984. Molecular Phylogeny and Barcoding of Caulerpa (Bryopsidales) Based on the tufA, rbcL, 18S rDNA and ITS rDNA Genes. This species resembles another Hawaiian Caulerpa species, C. sertularioides. Over the past decade it has spread along 60 km of the Mediterranean coastline and presently represents a potential risk to biodiversity. distichophylla, has been recognised for the first time in the Strait of Messina area, off the northeastern coast of Sicily (Tyrrhenian Sea, western Mediterranean). Another hypothesis proposes that C. taxifolia and Caulerpa mexicana Sonder ex Kützing are morphological variants of one another and hence conspecific taxa. Caulerpa taxifolia was officially eradicated from southern California in 2006. Genetic polymorphism in Caulerpa taxifolia (Ulvophyceae) chloroplast DNA revealed by a PCR‐based assay of the invasive Mediterranean strain. Molecular systematics, historical ecology, and phylogeography of Halimeda (Bryopsidales). Caulerpa mexicana has been found in the eastern Mediterranean since at least 1941. Caulerpa taxifolia was officially eradicated from southern California in 2006. 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. Phylogenetic analyses of Caulerpa taxifolia (Chlorophyta) and of its associated bacterial microflora provide clues to the origin of the Mediterranean introduction. Filling in the gaps with evolutionary genomics. Invasive Marine Algae: An Ecological Perspective. (Chlorophyta) supports a derived, incipient species status for the invasive strain Molecular authentication of Caulerpa (Chlorophyta) species along the eastern (Israeli) Mediterranean shores. 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. Based on morphological characters, the invasive green alga Caulerpa taxifolia var. 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. Since 2000, it had been found in two coastal water bodies in southern California (but has since been eradicated). Polymerase chain reaction–single strand conformation polymorphism analyses of nuclear and chloroplast DNA provide evidence for recombination, multiple introductions and nascent speciation in the Caulerpa taxifolia complex. Comparative DNA sequence analysis of the nuclear ribosomal cistron, including the 3′‐end of the 18S, ITS1, 5.8S, and ITS2 regions, show clear phylogenetic separation of the two taxa using parsimony and maximum likelihood analyses. DNA tests are necessary to distinguish the invasive Mediterranean strain from native C. taxifolia. In 1984, Caulerpa taxifolia (Vahl) C. Agardh was reported along the coast of Monaco. Intraspecific variation in seaweeds: The application of new tools and approaches. Native To: Caulerpa taxifolia is widespread in tropical habitats; the Mediterranean clone may have originated in Australia (Jousson et al. Analysis of rDNA ITS1 indels in Changes in shallow phytobenthic assemblages in southeastern Brazil, following the replacement of Sargassum vulgare (Phaeophyta) by Caulerpa scalpelliformis (Chlorophyta). Caulerpa mexicana has been found in the eastern Mediterranean since at least 1941.
