With respect to Caulerpa, Trono and Denila (1987) reported that pond cultured Caulerpa lentillifera in the Philippines can yield up to ∼1.5 kg wet wt/m2. Stolons branched, stout, naked, (0.5)–2.0–2.5 mm in diameter, to 0.3 m long. Over seventy species of Caulerpa are currently recognised, with many further divided into bewildering arrays of subspecies, varieties and Codium fragile, also considered as a notorious invader, was found growing on eelgrass rhizomes in Canada. E.A. Branching widely dichotomous, repeatedly dichotomous or subdichotomous. Inset: Habit. 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. In seagrass meadows, both the bottom (sand, mud, rocks, coral rubbles) and seagrasses themselves act as substrata for macroalgae (Phillips 1978, Phillips et al. It is popular as a human food because of its nutritional value such as … Rhizoids shortly stalked, branched. 1. Native To: Caulerpa taxifolia is widespread in tropical habitats; the Mediterranean clone may have originated in Australia (Jousson et al. Thalli filamentous from light green to dark green color forming mat-like inconspicuous congestions, consisting of creeping stolons and erect slender branches matted and interspersed with sand and shell particles. Growing on sandy-muddy bottom, on stones covered with sand in the middle intertidal to upper subtidal zones. GENUS Caulerpa (Gk. Green Feather Algae (Caulerpa sertularioides), A pretty algae species loved by green sea turtles and sea slugs in the shallow waters around Munyon Island. 1) covered a surface area of almost 0.6 km 2 .

But it does not … San Diego also has adopted an ordinance banning the possession, sale, and transport of the entire genus of Caulerpa within city limits. Rhizoids dichotomously branched, gradually tapering to apices. Distribution. occidentalis (J. Agardh) Børgesen]. Caulpera is a specie of large green algae and they often act as invasive species. Asexual reproduction by means of fragmentation leading to the production of clonal individuals is by far the most common means of propagation. C. glomerata is a reticulated filamentous green alga (Cladophorales) that methanol extracts and purified fractions showed antimicrobial activity against MDR A. baumannii. Caulerpa. Habit of young plant. The area included by the perimeter of the established colonies is called the ‘affected area’. In a subsequent report, Doty and Aguilar-Santos (1970) describe the isolation of a second toxic constituent, caulerpin, in several additional Caulerpa species, as well as the ability of a sea slug (Oxynoe panamensis) that feeds on Caulerpa to concentrate both compounds to levels greater than those found in the seaweed. Plant washed ashore by waves at Luhuitou village. North, Central, and South America, Atlantic islands, Caribbean islands, western Atlantic, Africa, Indian Ocean islands, South-west Asia, Asia (China), South-east Asia (Vietnam, Thailand, Philippines, Singapore), Australia and New Zealand, Pacific islands. The results indicated that among all tested algal extracts, those obtained from Caulerpa cupressoides exhibited the most antimicrobial activity against E. coli, while propanol extracts of Gracilaria edulis had most inhibition on the growth of K. pneumoniae. Caulerpa has only a single cell wall, surrounding the whole organism from the root tips to leaves. Present all year in the Mediterranean sea. Caulerpa sertularioides, a green alga spreading aggressively over coral reef communities in Culebra Bay, North Pacific of Costa Rica. INTRODUCTION The genus Caulerpa, described by Lamoroux in 1809 belongs to the group … Distribution. Sexual reproduction in members of the genus occurs only rarely. [3], The species is usually part of coastal and estuarine environments where it grows in sandy areas, as seagrass beds or on and around mangrove roots. 20 per page . The macroalgal component is variable in species composition and abundance and may contribute significantly to the structure and function of the seagrass community and is therefore an important component to consider (Heijs 1987, Verheij and Erftemeijer 1993, Jupp et al. Branches 2.5–5(–20) cm high, 4–5(–20) mm wide, stalked (1–3 mm high). Caulerpa taxifolia (Vahl): Caulerpa taxifolia (Killer Algae) is a light green macroalgal grow up to 2.8 m height in 40-60 cm deeper of tropical seas, 6-8 mm diameter of flattened upright leaf-like frond arising from the creeping stolons up to 3-15 cm long and from the base, the narrow tip upward small side branchlets are constructed opposite to the midrib 47, 48 Fig. Main content area. Ellen Lavoie1, Scott Braswell2 1,2: University of Washington, Molecular Analysis Facility, MolES, Seattle, WA Introduction: Caulerpa is a genus of tropical marine algae within the phylum Chlorophyta ... provide and increase in surface area Despite recent advances in taxonomy and phylogeny, there is still confusion about the delimitation and identification of some species due to tremendous phenotypic plasticity. Caulerpa sertularioides, also known as green feather algae,[1][2] is a species of seaweed in the Caulerpaceae family found in warm water environments. Of these, 50 taxa are newly reported from the Philippines. 1. Thallus light to dark green, consisting of creeping slender stolons 1(–2) mm in diameter, bearing branched rhizoids and erect branches 1–3 cm high. It has the ability to form a dense smothering blanket of growth on any surface (rock, sand or mud). In Australia, Paul et al. In the United States it is found from North Carolina to Florida. 1991). In the delineation of the drug-sensitive phase, the polysaccharides of SX4 and SP4 from C. brachypus and SP11 from C. latum showed potent anti-HSV-1 activities with IC50 values of 6.0, 7.5, and 6.9 μg/ml, respectively, even when added to the medium 8 h postinfection. Some species of green algae are also considered to be invasive; among the most notorious is Caulerpa taxifolia. [1] In Western Australia, it is found along the coast in the Kimberley region extending south to the Gascoyne. In the westernmost stations (S. Saba), boulders covered by a deposit of fine sands were colonised, whereas in the easternmost Tono, the amount of fine deposit was negligible. This may well be the first report of a toxic seaweed compound being transferred and biomagnified up a food chain. Commercial production of Ulva is limited: Japan produces ∼3000 tons (dry weight) annually (volume includes that of Enteromorpha) (Ohno and Largo, 2006) while South Africa produces ∼1100 tons (fresh weight) (Bolton et al., 2008). The branches bear numerous peltate, disc-like branchlets (blades), 1.5–3.5(–5) mm in diameter, on slender stalk 1–2 mm long. Growth in area invaded by Caulerpa taxifolia on French and Monaco coast(3) Photo: Deutsches Meeresmuseum, Stralsund P h o t o: Y. G l a d u, U P C Caulerpa racemosa, the grape algae Caulerpa taxifolia is not the only invasive species of this genus spreading in the Mediterranean Sea. da Gama, ... Renato C. Pereira, in Advances in Botanical Research, 2014. Caulerpa toxins, namely, caulerpin and caulerpinic acid, have also been shown to have insecticidal activity against the common house mosquito Culex pipiens (Alarif et al., 2010). Where seen? Growing on rocks covered with sand, dead coral colonies at low intertidal, upper subtidal (1–2 m depth) of moderately exposed shores, intermixed with other algal species in turf communities. 1. Main axes cylindrical and naked at the base becoming flat above, 0.8–1.5 mm broad. For example, the functional form-groups of seaweeds as epiphytes on Thalassodedron ciliatum in rock (den Hartog 1970, Barnabas 1982, 1991) are as follows: articulated calcareous macroalgae e.g., Jania adhaerens, Haliptilon subulatum, Halimeda spp. The absolute configurations of 1 , (+)‐ 2 and (‐)‐ 2 were elucidated by the method of ECD calculation. Plants in association with turf algae overgrowing artificial constructions of lobster farm (Vietnam). D. Cheney, in Seaweed in Health and Disease Prevention, 2016. Under these conditions it is relatively easy to esti-mate the surface area covered by the alga (referred to as the covered area) and to delimit the exact perimeter of the area of dispersal by SCUBA diving. They are unusual because they consist of only one cell with many nuclei, making them among the biggest single cells in the world. An additional compound, caulerpenyne, was isolated from Caulerpa (Amico et al., 1978) that was later shown to have ichthyotoxic and antigrazer activity (Paul et al., 1987). Inset: habit. Currently, more than 100 species are recognized worldwide. The Chinese and Japanese are among the prolific seaweed-eating people, and are accredited with recognizing its food value. In: California Conference on Biological Control III, … Inset: Habit (Okinawa, Japan). © Botany, University of Hawaii at Manoa 2001 A-43 Branches, feather-like, flattened, and upright, 3 - 10 cm high, rising from a creeping stolon (runner), 1 - 2 mm Caulerpa is a genus of seaweeds in the family Caulerpaceae (among the green algae). [3] It has feather-like fronds that arise from a common stolon. Caulerpa taxifolia. When low cover values for seagrasses occur, the diversity and number of macroalgal species are comparatively higher (Heijs 1985). Thallus dark green, light bluish green, dull green, or pale green sometimes yellowish-orange at the upper portions of branches, 2–3.5(–9) cm high, consisting of branched creeping stolons, 20–30 cm long, 2 mm in diameter bearing erect branches and rhizoids below.

Nataliya A. Milchakova, in. Growing on rocks covered with sand, dead coral colonies intermixed with other algal species in turf communities, commonly forming dense patches and occupying extensive areas of the bottom at the low intertidal zone of moderately exposed shores. March 2015. It is no wonder that sea vegetable is now known as the poor man's source of cheap protein and iodine, and has an export potential for tropical countries. 3. Biological control of killer algae, Caulerpa taxifolia. Erect branches grape-like in appearance, (1)–5–6(–15) cm high, with branchlets (2)–2.5–4 mm in diameter, spherical, subspherical, or club-shaped without constrictions between the branchlets and stalks. Monostroma is mainly produced by Japan at ∼1500 tons dry weight annually (Ohno and Largo, 2006). Caulerpa, Mediterranean clone; Killer algae. 1. Monodominant community occupying large areas. In habitat, the upper subtidal zone. Organic extracts from Caulerpa prolifera inhibited the growth of two gram-positive and one gram-negative unidentified marine bacteria (Smyrniotopoulos et al., 2003). Figure 1.15. Insets: a—Detail showing inner trabeculae of a creeping stolon; b—Chloroplasts. Keywords: Caulerpa macrodisca, first occurence, new record, Malaysia, Sabah, tufA gene. Distribution. T he invasive caulerpa algae genus break the rules of sa:vol because they have multiple nuclei. In T47D cell-conditioned media, 173 was shown to suppress hypoxic induction of the VEGF protein and tumor angiogenesis in vitro.111. -Small cells have more surface area and they can absorb more nutrients-A smaller volume also means that nutrients and materials can travel into or out of the cell quicker-Cells are also smaller because the ratio of surface area to volume is the most efficient . The quadrat technique can be used in both destructive (harvesting) and non-destructive (direct observation) sampling. Additionally, the immunostimulatory activity of Caulerpa lentillifera polysaccharides (CLP) on RAW264.7 mouse macrophage was evaluated by in vitro cell experiments. Your essentials are not going t get to where they are needed fast enough and neither are your waste. Creeping stolons 90–130(–150–200) μm in diameter, to several centimeters long, bearing dichotomously branched rhizoids. 2. They are able to do so because multiple nuclei helps efficiently to do so at their large size. Green alga Chlorophyta: Ulvophycees . It is also found throughout the Caribbean around Bermuda, Bahamas, Greater and Lesser Antilles and in the Gulf of Mexico and in the southern Atlantic Ocean to Brazil (Taylor 1979). The orientals prefer Porphyra, Gracilaria, and Eucheuma; the occidentals have Palmaria or ‘Dulse,’ Chondrus or ‘Irish Moss,’ and Porphyra or ‘Laver,’ to cite the more popular ones. Distribution. Growing Caulerpa Macro Algae in Marine Aquariums & Refugiums Caulerpa Macro Algae is a very popular and easy to grow macro algae. By continuing you agree to the use of cookies. Hainan Island, Luhuitou, April 2012. It is widely used ornamentally in aquariums, because it is considered attractive and neat in arrangement, and is easy to establish and care for.The alga has a stem (rhizome just above the seafloor. Their food preparations vary among European and American consumers, although salads, soups, pickles, jellies, etc. distichophylla collected from Southern Sicily (Italy) (Jongma et al., 2013). Branchlets few or densely arranged on erect axes (radially, alternately, pinnately, or irregularly). However, strong seasonality in the leaf area index of C. racemosa and C. taxifolia within the Mediterranean, combined with a weak rhizome structure, suggests that sediments maybe unprotected … The first report of a toxic constituent from a seaweed was that of caulerpicin from Caulerpa racemosa by Doty and Aguilar-Santos (1966). Growing on hard substrates covered with sand, on sandy bottom with rocks, in the middle, lower intertidal, subtidal zones (to 10 m deep), in sheltered and moderately wave-exposed sites, often in association with seagrasses. Apices pointed. Habit. Each axis connects each frond to a creeping stolon with a diameter of 2 to 2.5 mm (0.079 to 0.098 in) and a length of up to 2 metres (7 ft). This bill also establishes the same restrictions on several other species of the genus Caulerpa that are similar in appearance and are believed to have the ability to become invasive. 2. In addition, acetone extracts of Padina tetrastromatica and Laurencia cruciata had the greatest inhibitory influence on P. aeruginosa, while butanol extracts from Hypnea musciformis, Caulerpa cupressoides, and Chaetomorpha linoides exhibited the most antimicrobial activity against S. aureus. In the infamous bloom in Brittany, France, and Qingdao, China, the total biomass of Ulva that was collected reached up to 100,000 tons (Smetacek and Zingone, 2013) and over 1,000,000 tons (Liu et al., 2013), respectively. (2014) reported similar biomass yield values from the same species cultured in raceway. Caulerpa taxifolia cluster washed ashore by waves. In comparison to Rhodophyta and Ochrophyta, fewer AF compounds from Chlorophyta were described to date. Thallus bright dark or grass green consists of widely spreading stolons bearing erect branches above and rhizoids below. In habitat, the upper subtidal zone. Growing on sandy-rocky bottom to 1–2 m depth, at sites exposed to moderate wave action. A genus of toxic marine GREEN ALGAE found throughout tropical and subtropical seas. Pinnules flattened, regularly opposite, upcurved, sickle-shaped toward apices, slightly constricted at base, 0.3–0.5(–1) mm wide, (1.7)–2.5–6 mm long (4–6 times as long as broad), tapering to tips and the base. These two novel FAs were reported to be active at µM concentrations against Listonella anguillarum and MRSA. Central axis cylindrical, 430–500(–1000) μm in diameter. In the case of the aquarium strain of C.taxifolia only male gametes have been observed and this strain is apparently only vegetatively spreading ( 3.21 Zuljevic and Antolic, 2000). The extract was purified and acetylene sesquiterpenoid esters were isolated. In habitat, young plants in low intertidal rocky pool. Caulerpa cylindracea was collected in the Marine Protected Area of Torre Guaceto located in the Mediterranean Sea (Southern Adriatic Sea, Brindisi, Italy) at the depth of 8–10 m on the rocky bottom, during the season of maximum growth of the species when the alga dominates the benthic assemblages forming continuous dense meadows across the areas. Aside from their food use, the Japanese have made and marketed ‘Kombu-Cha’ – a kind of tea made out of processed Laminaria. One of the most striking features observed in any ecological community, including macroalgal and seagrass communities, is the variation in species abundance. Usually found in clumps, which can cover an area of about 40-50cm. Your surface area to volume ratio decreases dramatically the bigger you get. Lamououx. Species of Caulerpa and Codium, known in the Philippines as ‘lato’ (Visayan) and ‘pok-poklo’ (Ilokano), respectively, are the most common edible green algae among the South-east Asians. In contrast, in stressed or polluted (eutrophic) habitats, species diversity may be reduced but the occurrence of a particular species may be high with respect to abundance and biomass (Verheij and Erftemeijer 1993). Central and South America, Atlantic islands, Caribbean islands, western Atlantic, Africa, Indian Ocean islands, South-west Asia, Asia (China, Japan, Taiwan), South-east Asia (Vietnam, Thailand, Myanmar, Malaysia, Singapore, Indonesia, Philippines), Australia and New Zealand, Pacific islands. (2004b) have estimated anti-HSV-1 activity of natural sulfated polysaccharides from 10 green macroalgae (Enteromorpha compressa, Monostroma nitidum, Caulerpa brachypus, Caulerpa okamurai, Caulerpa scapelliformis, Chaetomorpha crassa, Chaetomorpha spiralis, Codium adhaerens, Codium fragille, and Codium latum). ... We are proud to offer a growing number of species in the caulerpa genus but want you to know the risks associated with these plants. As expected, green macroalgae also emerged as novel antiviral agents. Green seaweed from the genus of Caulerpa consists of one cell by many nuclei, often found in tropical and subtropical waters 14, 15. These, like the other brown and red seaweeds, are simply prepared as a salad with vinegar and a dash of salt. (2012) to have a biomass of ∼10 kg/m2, while those that invaded northern Chile had a biomass of approximately 22.9 kg/m2. So if diffusion time increases with size, it’s going to make the cell into one hot mess. Each of the fronds is upright and branched. Macroalgae can also be classified into functional form-groups (Littler and Littler 1980). An Appendix is provided at the end of this chapter, listing references for identification of macroalgae relevant to the 10 global regions described in Chapter 1. Representing the more popular edible brown seaweeds are Hizikia, Hydroclathrus, Laminaria, and Undaria. The branches bear numerous branchlets closely set on erect axis in all directions. 1982, Ogden and Ogden 1982, Fonseca and Fisher 1986, Heijs 1987, Bell and Pollard 1989, Borowitzka and Lethbridge 1989, Verheij and Erftemeijer 1993, Jupp et al. Quadrat sampling techniques can also be adapted for studies of marine plants such as seagrasses and associated macroalgae (Morozova-Vodyanitskaya 1936). [=Caulerpa racemosa var. Keywords Algae Caulerpa taxifolia Chlorophyta Coastal Invasive species Prediction models Introduction ... macroalgae in the genus Caulerpa are of particular concern because of their recent expansions, ability to propagate from asexual fragments, and negative impacts on the invaded communities. Branches dark green, simple or occasionally branched, ending abruptly in a short apex, shortly stalked, feather-like, oblong or broadly lanceolate, dwarf, 1–3 cm high, 4–8(–10) mm broad, with flat midrib, 1–3 mm broad and with pinnules on both sides of the midrib. Rhizoids fine, branched, yellowish. The inhibition zone varied from 17 to 83% of that observed with the biocide [bis-(tributylin) oxide] (TBTO). The relationships between morphology and photosynthetic parameters within the polymorphic genus Caulerpa… Dubbed the "killer algae", Caulerpa could have devastating ecological and economic consequences for California if it is allowed to become permanently established. It is also found in the Pacific Ocean along the Great Barrier Reef in Australia, Papua New Guinea, Philippines and Palau. Non-destructive techniques are less time consuming and many quadrats can be studied (Warner 1984). Erect filaments fastigiated, 1.5–3 cm high, branching opposite, alternate, dichotomous, or irregular. The new feather-like Caulerpa population … The macroalgae (green algae – Division Chlorophyta, brown algae – Division Phaeophyta and red algae – Division Rhodophyta) can be organized into life form categories (Taylor 1975, Bold and Wynne 1978, den Hartog 1979, Brouns and Heijs 1991): rhizophytic/epipelic (attached to mud and sand e.g., species of Caulerpa, Udotea, Avrainvillea); lithophytic/epilithic (living on stones, rocks, boulders or dead corals e.g., species of Amphiroa, Caulerpa, Halimeda, Sargassum); epiphytic (attached to seagrass leaves, stems, rhizomes and other macroalgae, e.g., Jania adhaerens, Valonia macrophysa, Padina boryana); epizoic (attached to mollusc shells or polychaete tubes e.g., Enteromorpha intestinalis); loose-lying or drift macroalgae (detached or floating e.g., Colpomenia sinuosa, Hydroclathrus clathratus, Ulva reticulata). Europe, North, Central, and South America, Atlantic islands, Caribbean islands, western Atlantic, Africa, Indian Ocean islands, South-west Asia, Asia (China, Japan, Taiwan), South-east Asia (Vietnam, Thailand, Myanmar, Malaysia, Singapore, Indonesia, Philippines), Australia and New Zealand, Pacific islands. In the nondestructive method, macroalgae within the quadrat are not removed, allowing short-term studies to be conducted or permanent quadrats can be used for seasonal and long-term studies (Polderman 1980, Heijs 1985, 1987, Jupp et al. Among turf algae. 1. A techniques comparison of preparation for the ultrastructure of trabeculae in Caulerpa sp. 106 The Caulerpa genus has classically been divided into two major albeit tenuous groups, the frond-like bilateral leaf species, which grow below the littoral zone in relatively still water, and the radially branched species, which characteristically prefer habitats associated with … In this regard, different algal species (Caulerpa cupressoides, Chaetomorpha linoides, Enteromorpha intestinalis, Gracilaria edulis, Colpomenia sinuosa, Hypnea musciformis, Laurencia cruciata, Padina boergesenii, Padina tetrastromatica, S. wightii, and U. lactuca) were extracted by various solvents (acetone, n-butanol, propanol, water, and benzene), and were tested against postoperative infectious drug–resistant bacteria (E. coli, K. pneumoniae, P. aeruginosa, S. pyogens, and S. aureus). Normally, "Grape Caulerpa" is Caulerpa racemosa, or one of the variations of C. racemosa. Within, the liquid of the cell flows freely. Results and Discussion. Caulerpa taxifolia (Vahl) C. Agardh 1822 Invasive Alga . Distribution. For macroalgae, abundance is usually based on number of individuals per species, but other variables such as biomass and percent cover can also be used (Saito and Atobe 1970, Heijs 1985, 1987, Brouns and Heijs 1991, Verheij and Erftemeijer 1993, Bandeira and António 1996, Milchakova 1999). Moreover, EPA with antibacterial activity on a broad spectrum of Gram-positive and Gram-negative bacteria was identified in the FA profile of P. tricornutum.106, Bujang Japar Sidik, ... Nataliya A. Milchakova, in Global Seagrass Research Methods, 2001. Distribution. The rhizoids stalked, repeatedly branched, and tapering to slender apices. New branches often proliferating from the midrib. Within the giant coenocytic (single cell, multi-nucleated), unique structures called trabeculae appear in a network to form what appears as scaffolding. Green seaweed from the genus of Caulerpa consists of one cell by many nuclei, often found in tropical and subtropical waters ... area % 1: 2.749 min: Benzaldehyde, 2-methyl-C 8 H 8 O .

Thallus light or pale green consisting of very fine creeping stolons, 0.4–0.8(–1) mm in diameter, bearing erect branches to 1 cm high and rhizoid-bearing branches. Invasive green algae in a western Mediterranean Marine Protected Area: interaction of photophilous sponges with Caulerpa cylindracea - R. Manconi, A. Padiglia, B. M. Padedda, R. Pronzato Apices rounded conical and mucronate. The new feather-like Caulerpa population (Fig. 114 In an unrelated study, 173 has been described as a green inhibitor of mild steel corrosion, where AFM and IR experiments suggest that 173 forms a protective surface on the surface of mild steel, thereby preventing corrosion.115 There have been no reports of caulersin biological activity. Via column chromatography, reverse-phase HPLC, and H-NMR spectroscopy, the PUFA eicosapentaenoic acid (EPA) was identified as an antimicrobial compound active against a broad spectrum of microorganisms, including MDR S. aureus bacterium.110, Postoperative infections can cause serious problems, including failure of the surgical procedure, other surgical complications, organ failure, and death. Coral Reefs. 1996). How many species are rare or common? Lutzu, in Antibiotic Resistance, 2016, MDR bacteria such as S. aureus, K. pneumoniae, Acinetobacter baumannii, P. aeruginosa, and M. tuberculosis are at the center of great attention in health-care institutions. GC-MS analysis also revealed the existence of hydrocarbon compounds in purified fractions of C. glomerata with antibacterial activity.111, Monounsaturated fatty acid, (9Z)-hexadecenoic acid, and the relatively unusual PUFA (6Z,9Z,12Z)-hexadecatrienoic acid were isolated from P. tricornutum. The steroid yengaroside-A, and the clerosterol galactoside isolated from Codium iyengarii exhibited antibacterial activity (Ali, Saleem, Yamdagni, & Ali, 2002). Caulerpa sertularioides , also known as green feather algae , [1] [2] is a species of seaweed in the Caulerpaceae family found in warm water environments. What is their relative abundance? The antinociceptive potential of extracts from algae of the genus Caulerpa was evaluated using three well-accepted murine pain models, namely acetic acid-induced writhing, hot plate and formalin-induced nociception tests.
