The Situation: Caulerpa taxifolia is an invasive alga that is causing serious environmental problems in the Mediterranean Sea.This invasive weed was discovered in southern California and New South Wales, Australia in 2000. Species Overview. r-selected life histories (use of pioneer habit, short generation time, high fecundity, and high growth rates) and the ability to shift between r- and K-selected strategies (3.21a, Sakai et al, 2001). Native Introduced Native and Introduced. Despite recent advances in taxonomy and phylogeny, there is still confusion about the delimitation and identification of some species due to tremendous phenotypic plasticity. Currently, more than 100 species are recognized worldwide. Jump to: navigation, search. In December 1999, the Aquatic Nuisance Species Task Force (ANSTF) established the Caulerpa taxifolia (Mediterranean strain) Prevention Committee. Interpreting Wetland Status.

Project description: Background. Eradication of Caulerpa taxifolia in the US five years after discovery: are we there yet? Mapping Caulerpa racemosa's expansion is difficult due to its ability to invade deeper areas rarely visited by free-divers and to its less noticable size and colour. In: 13th International Conference on Aquatic Invasive Species. The fronds are flattened laterally and the small side branchlets are constricted at the base (where they attach to the midrib of each frond), are opposite in their attachment to the midrib (as opposed to alternating) and curve upwards and narrow towards the tip. The biological characteristics of Elysia subornata (Mollusca: Opisthobranchia) were studied in an aquarium to assess its risks and chance of success as a potential biological control agent against the invasive alga Caulerpa taxifolia (Chlorophyta) in the Mediterranean Sea. Common Name - caulerpa. Nonetheless, C.taxifolia corresponds to most of the characteristics common to successful colonists across taxa; i.e. Similar Species. Caulerpa taxifolia is a light green macroalga with upright leaf-like fronds arising from creeping stolons. The invasive clone, or strain, of Caulerpa taxifolia shows little genetic variation, indicating that it propagates by fragmentation. Wetland Status. Although the federal government lists caulerpa taxifolia on the federal noxious weed list, there are other caulerpa species for sale. ID 16341 Symbol Key CAULE Common Name caulerpa Family Caulerpaceae Category AL Division Chlorophyta US Nativity N/A US/NA Plant Yes State Distribution N/A Growth Habit N/A Caulerpa species are considered to produce the biggest single cells of any living organism on Earth [1,2]. The Caulerpa taxifolia populations form a monophyletic clade, as a sister group to C. sertularioides. Caulerpa species are eaten as delicacies in some Pacific countries, 89 and it was the search for the distinctive “peppery principle” of C. racemosa that led the initial investigation into this genus. We analysed insertion-deletion patterns in 159 published sequences of ITS1 for Caulerpa taxifolia (Vahl) C. Agardh collected from 55 localities throughout the species' range. The sea grape (Caulerpa racemosa) has a chlorophyll pigment that can be extracted using a non-polar solvent. As it spreads into the western Mediterranean, it even seems to be capable of out-competing Caulerpa taxifolia! ... Characteristics Description. Anderson LWJ, 2004. Linda Walters, Ecology and Management of the Invasive Marine Macroalga Caulerpa taxifolia, Management of Invasive Weeds, 10.1007/978-1-4020-9202-2, (287-318), (2009). We here describe the molecular characteristics of rRNA gene, including the internal transcribed spacers (ITS) in this genus and a comparison was made with associated species sequences registered in the GenBank. Habitat effect on spatio-temporal variability in size and density of the introduced alga Caulerpa taxifolia. Photo: Keoki Stender Caulerpa Caulerpa taxifolia Caulerpa taxifolia is an invasive marine alga that is widely used as a decorative plant in aquaria. And Its . 20-24 September 2004, Ennis, County Clare, Ireland. This species feeds only on Caulerpa and has benthic larval development. Caulerpa taxifolia is a marine, green alga, a certain strain of which is invading sectors of the western coasts of the Mediterranean Sea where it grows much more robustly than it does in its native range.In the Mediterranean it has spread into thousands of hectares where it fills the water column with hundreds of tons of plant biomass per hectare. Chlorophyll as a natural dye has unstable characteristics of temperatu USDA Plant Characteristics Caulerpa. FIRST OCCURENCE OF CAULERPA MACRODISCA (CAULERPACEAE, CHLOROPHYTA) IN MALAYSIA BASED ON THE ... C. sertulariodes, C. taxifolia and C. verticillata (Phang, 2007). On the basis of morphological and molecular studies (nuclear ribosomal internal transcribed spacer (ITS)), we report for the first time C. taxifolia on the Levantine coast (Gulf of Iskenderun, SE Turkey). Caulerpa racemosa is invading much faster than Caulerpa taxifolia. The Plants Database includes the following 1 species of Caulerpa .

Caulerpa taxifolia is a chlorophyte consisting of a single cell containing potentially thousands of nuclei. ID - 16341. The biodiversity assessment of different taxa of the genus Caulerpa is of interest from the context of morphological plasticity, invasive potential of some species and biotechnological and pharmacological applications. Since its first accidental introduction into the Mediterranean Sea, Caulerpa taxifolia (Vahl) C. Agardh has spread to six Mediterranean countries and has become a major ecological problem.

Although unicellular, Caulerpa develops pseudo organs similar to roots, shoots, and leaves of more complex plants. The two species, Caulerpa taxifolia and Caulerpa prolifera, grow in the Mediterranean Sea, but while C. prolifera belongs to the native vegetation, C. taxifolia is an invasive species (Williams 2007).
