In this case, Caulerpa taxifolia was bred at the Stuttgart Aquarium in Germany… en In 1995 the LIFE instrument accepted a multinational project to monitor the expansion of Caulerpa Taxifolia in the Mediterranean (and not for its extraction). was acknowledged by the government of the United C. taxifolia is a green marine macro-algae native to tropical waters of the Indian, Pacific and Atlantic oceans. used to completely cover the plants, and then a commercially. entanglement with fishing nets and choked access to harbors and marinas. ... it had been bred by humans. http://mbnms.nos.noaa.gov/Research/techreports/Caulerpa.html, Madl, Pierre and Maricela Caulerpa translation in English-German dictionary. The threat it poses to marine environments an accelerated growth rate. [citation needed]. taxifolia. It is native to shallow water habitats, growing on small rocks and coral fragments. Caulerpa is a genus of green algae that includes about 75 different species. identify any benefits associated with this species. Baden, former state on the east bank of the Rhine River in the southwestern corner of Germany, now the western part of the Baden-Württemberg Land (state) of Germany. The appearance off the California coast was most probably caused by an aquarium owner improperly dumping the contents, allowing C. taxifolia to flow through a storm sewer into the lagoon where the invasion was discovered. year. It was everywhere. widespread economic harm through reduction of marine fisheries yields, portions of the Mediterranean but with no long-term Introduced Species Summary Project For these reasons it has been identified as Control probably leaked into the environment. Level Diagnosis: Highest Priority. This concern earned the algae the dubious nickname "Killer Algae" after the title of a book written on the subject. Attempts to remove plants mechanically with It is a native species in Hawaii where it has not exhibited invasive tendencies. Then chlorine was poured in through tubes which fed into certain openings in the tarpaulin: the interior of the tarpaulin filled up with chlorine and killed living organisms inside it, not only the unwanted alga but also fish, invertebrates and other seaweeds. California has since passed a law forbidding the possession, sale or transport of Caulerpa taxifolia within the state. The director of the museum argued that this invasion probably happened naturally, the result of ocean currents carrying a tropical species into the area. In 1980, the staff at the Wilhelma Zoo in Stuttgart, Germany found that a specific strain of this alga thrived in cold aquarium environments. Thus, this alga has been found to jump from the coast of one port city to the coast of another port city. 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. repr… 2, 1996., www.gcrio.org/Consequences/vol2no2/article2.html. Ripley, and L. Roy. A species profile for Caulerpa, Mediterranean Clone. Original Mode(s) of Despite claims that as many as half of fish species have disappeared from areas where Caulerpa grows,[citation needed] scientific studies have shown that fish diversity and biomass are equal or greater in Caulerpa meadows than in seagrass beds,[9] that Caulerpa had no effect on composition or richness of fish species,[10] and that species richness and epiphytic plant diversity is greater in Caulerpa than in pure sea grass. Threat(s): across a sandy bottomed sea floor alters the nutrient dynamics of the Throughout the 80s and 90s the German-bred algae had been sent to aquaria around the world. German shepherd A C. taxifolia on display at the National Museum of Nature and Science in Tokyo, Japan. Invasion Biology: Critique of a Pseudoscience. Caulerpa The killing of such other organisms was not desirable but was deemed preferable to letting the algae grow unchecked. Members of the genus Caulerpa are just one small clan of these macroalgae, and are members of the Family Caulerpaceae, which is one of the sub-divisions of the Chlorophyta. Jaubert, J.M., J.R.M. addition to the profound threat to biodiversity, it is likely to cause This is in contrast to plants which produce a variety of toxins, but in reduced amounts. spread is extremely urgent. Caulerpa taxifolia is known to have crowded out the sea grasses 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.

In-depth article on invasions of Caulerpa taxifolia, source as escaped aquarium plant, etc. displaces rich marine habitats that support a variety of fish and invertebrate 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. Life out of bounds: Bio-invasion in a borderless world. It is thought that the seaweed was accidentally released into coastal waters of the Mediterranean Sea just below Jacques Cousteau's Oceanographic Museum of Monaco in 1984. An entire plant can grow from a 2 cm fragment. Monterey Bay National Marine Sanctuary Fact Sheet: Caulerpa taxifolia Description: Green algae with feather-like branches, leaf is 5-65 cm in length, tropical in origin, found in Caribbean Sea and Indian Ocean, hybrid form found in Mediterranean Sea is much larger (plants up to 10 ft.), and can survive out of water for up to 10 days. Caulerpa taxifolia has gained worldwide attention and the nickname "killer algae" because of its great success in coastal Mediterranean waters. covered more than 11,000 acres along the coast of the Mediterranean, reaching North Africa. It is thought that Caulerpa species have such invasive properties in these regions due to their capability to thrive in temperate waters, along with their freedom from natural predators. identify any benefits associated with this species. It Caulerpa will happily reproduce asexually 95% of the time. This slug is believed to feed exclusively on C. taxifolia, by sticking its proboscis into the stem and sucking out the white viscous liquid inside the stem: this causes the alga to become limp, discolored, and dead. completely eradicated there now), and the Southeastern coast of Australia. Prohibited Species under the Federal Noxious Weed Act. On the other hand, studies have found that there is reduced pollution and toxicity in waters where it grows invasively, as around port cities in the Mediterranean. Caulerpa. tropical waters, while the hybrid form grows much larger with plants up to 10 unpalatable to general herbivores, and seems to grow unrestrained and develop There is concern about a possible transfer of toxins through the food Caulerpa taxifolia is a single celled organism, but this is often overlooked because of its complexity and size. in the Mediterranean have been unsuccessful because depths, it seems to grow to the underwater limits of vegetation. contains a toxin that is not harmful to humans but may be lethal to certain organisms.

It is fairly common in the aquarium trade and is often used as a nutrient exporter in the refugium. Thus, in contrast to widely publicized reports to the contrary, the species appears to have many beneficial ecological effects on aquatic communities in the Mediterranean Sea. Original concerns about it decreasing biodiversity of fauna have also been allayed, as species counts have shown this remains about the same. and animals as it colonizes an area with great monotypic stands of vegetation. Mackenzie, Debbie, The Starving Ocean, July 2001.  http://www.fisherycrisis.com/seaweed.html, Makowka, J.

Caulerpa taxifolia was officially eradicated from southern California in 2006. It might be outdated or ideologically biased. The alga has a stem (rhizome just above the seafloor. two species of snail have been A clone of the species was cultured for display at the Stuttgart Aquarium in Germany and provided to aquariums in France and Monaco. Frakes, T.A. In the 1800s, three men in Munich bred a bulldog with a breed of unknown origin, and continued that experiment for a few more generations. From this stem grow vertical fern-like pinnae, whose blades are flat like those of the yew (Taxus), hence the species name taxifolia. identified that attack the algae, the outbreak [5] Its author, Marine biologist Alexandre Meinesz first discovered the alga in the 1980s, and requested the help of the Monaco Oceanographic Museum, which sat right next to the first known C. taxifolia patch. They were trying to identify a hearty breed spread to cover more than 2.5 acres in less than five years and by 1997 it The most famous breed developed in Germany is of course the German Shepherd, a medium-sized dog that slightly resembles a wolf. 2003.

This breed is one of smartest in the world and can take on any given task. Mode(s) of Introduction: The hybrid form of Caulerpa taxifolia was most likely produced as a result of the tropical form having been captively bred for a number of years by the Saltwater Aquarium at the Wilhelmina Zoo in Stuttgart Germany. 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. Theodoropoulos, David. Caulerpa a genus of green algae of the order Siphonales.There are about 60 species inhabiting tropical and subtropicalseas. quickly.

And, at least in the aquarium hobby, the genus name is also used as their common name. Caulerpa taxifolia is a species of seaweed, an alga of the genus Caulerpa native to the Pacific Ocean and Caribbean Sea. 1. Unlike most aquarium macro algae, C. taxifolia (Killer Algae) has the appearance of a vascular plant with "leaves" arranged neatly up stalks, like a fern. habitats like eelgrass beds that sustain a complex food chain leaving the area In the wild, the caulerpa would be doing this to get up and move to another, less stressful area. among the 100 worst invasive alien species threatening biodiversity.
