The invasive clone, or strain, of Caulerpa taxifolia shows little genetic variation, indicating that it propagates by fragmentation. Please see more information here for aquarium owners or see our “ Dont Let it Loose ” campaign page.

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. Caulerpa species are considered to produce the biggest single cells of any living organism on Earth [1,2]. Caulerpa are thought to be invasive due to their historic and ongoing invasions of U.S. and foreign waters; Caulerpa taxifolia (Aquarium or Mediterranean strain), Caulerpa brachypus and Caulerpa racemosa. Chlorophyll as a natural dye has unstable characteristics of temperatu 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. The expansion in the Mediterranea of the green alga Caulerpa taxifolia has progressed steadily since 1984. Family - Caulerpaceae. Wildlife. Species from this family produce a wide range of metabolites suitable for biotechnology applications. Caulerpa taxifolia, Caulerpa sertularioides, Caulerpa mexicana, Caulerpa ashmeadii, Caulerpa scalpelliformis, ... Characteristics: Individual or clusters of oval to tear-shaped balloon-like blades (up to 3 cm). 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. Common Name - caulerpa. Key Points Archaeplastida are typically associated with their relationship to land plants; in addition, molecular evidence shows that Archaeplastida evolved from an endosymbiotic relationship between a heterotrophic protist and a cyanobacterium. Caulerpa taxifolia. Like many other species of this genus, Caulerpa taxifolia has some unique growth characteristics, besides being siphonous, that promote its … 1998. Related Links.

Caulerpa taxifolia was officially eradicated from southern California in 2006. 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. ... Characteristics Description. California's reaction to Caulerpa taxifolia: a model for invasive species rapid response. Caulerpa racemosa is invading much faster than Caulerpa taxifolia. Currently, more than 100 species are recognized worldwide. 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). Nonetheless, C.taxifolia corresponds to most of the characteristics common to successful colonists across taxa; i.e. Although the federal government lists caulerpa taxifolia on the federal noxious weed list, there are other caulerpa species for sale. ID - 16341. Native Introduced Native and Introduced. Ceccherelli, Giulia; Cinelli, Francisco. The genus Caulerpa is highly diverse, especially in the Caribbean Sea, the Indo-Malay archipelago and the temperate waters of southern Australia. Despite recent advances in taxonomy and phylogeny, there is still confusion about the delimitation and identification of some species due to tremendous phenotypic plasticity. 328-333. 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. 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).
