The six species of Caulerpafound in this study are of pantropical in distribution. Meskipun invasif di daerah beriklim sedang, spesies Caulerpa terutama C. racemosa dan C. lentillifera (lato) dipanen dan dikonsumsi sebagai makanan, terutama di Filipina. The genus Caulerpa is highly diverse, especially in the Caribbean Sea, the Indo-Malay archipelago and the temperate waters of southern Australia. corynephora (Montagne) Weber-van Bosse) and C. ashmeadii Harvey from mangrove channels on the Thai Andaman Sea coast, When tested on the 20 previously described syngens, it revealed one unexpected multi-clone effect on mating. In this study, the proximate nutrient composition, phytochemical, anti-oxidant and anti-diabetic properties of sea grape C. racemosa collected from culture fishponds in Johor, Malaysia were analysed. Twenty-three (23) taxa were accounted for among the collec- tions deposited in the University of San Carlos Herbarium (CEBU). Further, the taxonomical descriptions along with distribution and GPS data, abundance, ecology, economic importance etc. were found on Guam's fringing reef flat. was higher than in the Gulf of Thailand (7 spp.). After five weeks, they formed … Join ResearchGate to find the people and research you need to help your work. During ... M.A. Estrada JL, Bautista NS, Dionisio-Sese ML. Suitable conservation measures identification along with awreness campaign and developing protected areas. Using a lab experiment, we tested hypotheses about survival and morphological change under different sedimentation regimes. Scale bar : 2 ram. Caulerpa racemosa (Forsskal) J. Agardh is a green seaweed used as food and folk medicine since ancient times in the Indo-Pacific region, particularly in southeast Asia. This alga will be eaten only by certain animals such as the Mediterranean bream or saupe, Sarpa salpa. Elongation of fronds and reduced frond density are commonly observed morphological adaptations that allow for more efficient light uptake with water depth, i.e. into creeping rhizomes and upright axes. Settled zygotes, 3hr after copulation. At the current rate of spreading further rapid extension of its range is to be feared. Assessment, abundance and composition of fish and fisheries of Ganga river. De Senerpont Domis et al. Currently, more than 100 species are recognized worldwide. Comparison of morphological characters between different Caulerpa species (in mm). Despite recent advances in taxonomy and phylogeny, there is still confusion about the delimitation and identification of some species due to tremendous phenotypic plasticity. The life‐cycle system of Ulotrichales, a major order of Ulvophyceae, remains controversial because it is unclear whether the Codiolum phase, a characteristic unicellular diploid generation in ulotrichalean algae, is a zygote or a sporophyte. The name Caulerpa means "creeping stem," from Greek καυλος (kaulos), a stem, and ερπω (erpo), to creep. 12. Fertile plant with protoplasmic networks, one day before liberation of gametes. laetevirens, occidentalis and turbinata were found to represent environmentally induced forms of a single species, for which the earlier‐described C. chemnitzia, previously regarded as a synonym of C. racemosa var. and light intensity on the formation of assimilators were investigated with 25 combinations of 5 temperatures (20.0–30.0C) The method was used successfully with the colonial green flagellate, Pandorina morum Bory de St. Vincent, to identify a new pair of milling types (syngen). Reproduction, development and morphological variation of the marine green algaCaulerpa racemosa var.peltata from the southern part of Japan were studied in culture in the laboratory. Two species, Kappaphycus alverezii (Doty) Doty ex P. Silva and Eucheuma denticulatum (Burman) Collins & Hervey, were deliberately introduced for mariculture in the 1980s, but the farming failed and no relicts of these introductions have been detected. IDENTIFICATION: Caulerpa racemosa is a highly variable species. Morphological variations among 8 species of Caulerpa collected from Gujarat and Maharashtra coast were studied. Each upright axis successively formed ramuli and developed into an assimilator. Protoplasmic network in a fertile assimilator. We quantitatively showed that Codiolum phases grew extremely large and produced numerous zoospores. Biodiversitas 21: 1823-1832. To the east, it now occurs on the whole of the eastern side of Cap Martin (3km from Monaco) and is spreading over the west face. Larvae mainly feed by sucking the cell content of green filamentous algae. species of the coastal environment in the Kuroshio Current region was examined by means of biological and socio/economical approaches. Previous investigations based on this approach have incorporated only a limited number of specimens of Caulerpa from the Philippines. Standard method of herbarium specimen preparation was used that involved field visit, specimen … Identity Nomenclature Valid scientific name The genus Caulerpa J.V.Lamouroux 1809 was originally erected to include eight species previously described in the genus Fucus L., 1753. Reproduction and development of C. racemosa var. Two species, Kappaphycus alverezii (Doty) Doty ex P. Silva and Eucheuma denticulatum (Burman) Collins & Hervey, were deliberately introduced for mariculture in the 1980s, but the farming failed and no relicts of these introductions have been detected. Currently, more than 100 species are recognized worldwide. Resolving phenotypic plasticity and species designation in the morphology challenging Caulerpa racemosa-peltata complex (Caulerpaceae, Chlorophyta). The protocol used for morphometric analysis in the study was described by, ... Morphometric parameters measured for assimilators, ramuli and rhizoids described by. 65-day-old germling with two lower thin filaments and one upper thick filament. Journal of Phycology 50, 32 – 54. In addition we formally recognize the synonymy ofC. The results confirm the presence of eight Caulerpa species in Thai waters, i.e., C. chemnitzia, C. lentillifera, C. macrodisca, C. racemosa, C. serrulata, C. sertularioides, C. taxifolia and C. verticillata. Arrow indicates the original spherical body. High diversity was observed in the following taxa: Caulerpa cupressoides (Vahl) C.Agardh, with two forms: disticha and elegans; C. racemosa (Forsskål) J.Agardh, with five varieties: lamourouxii, peltata, uvifera, macrophysa, and turbinata; and C. sertularioides (S.G. Gmelin) Howe with two forms: longiseta and brevipes. Biomasa yang memiliki stok tertinggi diperoleh oleh C. cupressoides dengan biomassa rata-rata 26,16 ± 2,44 (SE) g berat kering/m-2 , sedangkan C. microphysa memiliki biomassa stok yang berdiri paling sedikit dengan rata-rata 9,16 ± 0,26 g berat kering/m-2. Collected samples were later sorted to species. Morphological variation of two common sea grapes (Caulerpa lentillifera and Caulerpa racemosa) from selected regions in the Philippines. More studies are necessary to understand better the ecology (invasiveness, the functional role of its microbiome) and the biology (reproduction, life cycle, and metabolism) of Caulerpa species, especially for economical species. 13-16, 100 ~m. and Caulerpa spp as indicator The flora now includes 134 species and 83 genera of Rhodophyta, 23 species and 15 genera of Phaeophyceae, and 48 species and 25 genera of Chlorophyta. In those sites which it colonized three years ago, its coverage now reached 100% over extensive areas in depths between 5-25m. Planozygote. 4. Samples were cleaned of all debris, epiphytes, and sediments (Thibaut et al 2004; CIFRI-CDA-ICZM Consultancy Project 2011-2016, The project envisages to formulate guidelines for estuarine resource management for augmenting fisheries on an ecosystem based approach with a clear focus on (i) generating information on seasonal, Assessment of diversity and abundance of gastropods and bivalves in Mahanadi, 1. Ninety-five percent of the flora consists of widely distributed species (Western-Central Pacific, Indo-Pacific, pan-tropical / -subtropical, and cosmopolitan), and there is a very low level of endemism (1.3 %), which, it is suggested, may be due to the relatively young age of the Samoan Archipelago and to its position mid-way along the Indo-West Pacific biodiversity gradient. Central Marine Fisheries Research Institute, Morphological variation of two common sea grapes (Caulerpa lentillifera and Caulerpa racemosa) from selected regions in the Philippines, STANDING-STOCK BIOMASS AND DIVERSITY OF Caulerpa (Chlorophyta) IN SOLONG-ON, SIQUIJOR ISLAND, PHILIPPINES, Culture studies on Caulerpa (Caulerpales, Chlorophyceae) II. on a fossil periglacial slope deposits in the Hidaka Mountains, Hokkaido, Japan, and a total of 2350 stones were measured in order to evaluate a-axis length and clast shape separately influence its fabrics. This species contains the toxin, caulerpenyn, which may play a role against other organisms such as grazers, epiphytes and competitors. © 2008-2020 ResearchGate GmbH. Thus, the occurrence of this species in Antalya harbour should be considered temporary, not as an indication of the expansion of the distribution area of this lessepian species in the Mediterranean Sea. Comparisons of Samoan specimens with collections from other Pacific Island material held in SUVA-A, and historical collections from Samoa algae held in UC and BISH, are also made to expand the scope of the treatments. Morphogenetic responses of C. racemosa vat. The first report of a toxic constituent from a seaweed was that of caulerpicin from Caulerpa racemosa by Doty and Aguilar-Santos (1966). It developed first in the sea immediately below the oceanographic museum, and resisted winter temperatures of 11-13°C. Identification: The distinctive, frond-like morphology of Caulerpa taxifolia (under high sunlight conditions) can be distinguished from the other Caulerpa species to which it is most similar by the nature of its frond pinnules and its stolon. inedit., Codium geppiorum O. Schmidt and Gracilaria ephemera Skelton, South & Millar. The flora now includes 134 species and 83 genera of Rhodophyta, 23 species and 15 genera of Phaeophyceae, and 48 species and 25 genera of Chlorophyta. At larger spatial scales, frond length and width decreased with increased latitude, but latitude was less important in explaining the variation C. filiformis’ length than were depth or sedimentation. The protected environment such as tide pools is found to be more conducive as larger specimens were collected from these areas; here reduced wave action allowed species to grow relatively larger. Biological Invasions, 3:201-210. Analisis korespondensi kanonik (CCA) mengungkapkan bahwa suhu dan jenis substrat adalah pendorong utama biomassa Caulerpa. Caulerpa is consumed mostly in Asia and Oceania, but its popularity tends to be on the increase in western countries with new nutritional practices (vegetarians, vegans, health foods). 4, 500 ~m ; Figs. Molecular analyses revealed six species-level clades: C. verticillata,C. In accordance with recent studies, our morphological and DNA results warrant the recognition of C. chemnitzia to comprise the morphological entities C. laetevirens, C. peltata and C. vanbossea complex. cylindracea, is an invasive ... Es común encontrar dos o más formas, reconocidas taxonómicamente, en una misma planta. were produced monoeciously and copulated with each other. The functional form theory predicts that surface area vs. Volume ratio (SA:V) and maximum productivity (P max) decrease as morphological complexity of an algal thallus increases.The genus Caulerpa demonstrates a tremendous range of morphological forms as well as interspecific plasticity which make it ideal to study intrageneric relationships between photosynthesis and morphology. On this bases we had clarified fundamental processes in bleaching and coral diseases. Estrada JL, Bautista NS, Dionisio-Sese ML.
