We used field measurements to test hypotheses about morphological variability in C. filiformis in relation to local- and large-scale environmental variation in water depth, sediment cover and latitude. resulting in the formation of creeping, filamentous, protonema-like plants. On this bases we had clarified fundamental processes in bleaching and coral diseases. 17. Morphological characters, such as distance between modules, number of modules, stolon branches and rhizoid clusters per centimeter of stolon, indicated a uniformity among species within a specific habitat. Previous investigations based on this approach have incorporated only a limited number of specimens of Caulerpa from the Philippines. Morphological variation of two common sea grapes (Caulerpa lentillifera and Caulerpa racemosa) from selected regions in the Philippines. 15. turbinata, is reinstated. Its accidental introduction into the natural environment dates from 1984. -from English summary. The following new combinations are made: Hinksia van-bosseae (Setchell & Gardner) Skelton and South (previously Ectocarpus van-bosseae), Antithamnionella simplex (Dawson) Skelton and South (previously Antithamnion simplex), Neosiphonia ferulacea (Suhr ex J. Agardh) Skelton and South (previously Polysiphonia ferulacea Suhr ex J. Agardh), Neosiphonia howei (Hollenberg in W.R. Taylor) South and Skelton (previously Polysiphonia howei Hollenberg in W.R. Taylor), and Neosiphonia polyphysa (Kutzing) South and Skelton (previously Polysiphonia polyphysa Kutzing. 13. 3. Caulerpa is a genus of seaweeds in the family Caulerpaceae (among the green algae).They are unusual because they consist of only one cell with many nuclei, making them among the biggest single cells in the world.A species in the Mediterranean can have a stolon more than 3 metres (9.8 ft) long, with up to 200 fronds.This species can be invasive from time to time. The following new combinations are made: Hinksia van-bosseae (Setchell & Gardner) Skelton and South (previously Ectocarpus van-bosseae), Antithamnionella simplex (Dawson) Skelton and South (previously Antithamnion simplex), Neosiphonia ferulacea (Suhr ex J.

All species described in this book are based on primary collections exclusively made for this purpose and truly reflect the current status of seaweed biodiversity of Gujarat coast. 3. Refer to Fig. Anisogamous biflagellate male and female gametes Further, one of the species showed a unique fimbriate structure in head pole region of the girdle band. 10. In New South Wales, Australia, the abundance and range of the native green macroalga Caulerpa filiformis have increased over recent decades, apparently associated with sediment disturbance. via morphological variation) may allow for competitive dominance. 4. Most of coral reefs research were conducted on the bases of filed obser, United States has emerged as the top market for Chinese silk and silk products. Although recent molecular studies have indicated the presence of a number of distinct species within the Caulerpa racemosa-peltata complex, due to the difficulties presented by high levels of phenotypic plasticity and the large number of synonyms, infra-specific taxa, and names of uncertain affinity, taxonomic proposals are yet to be made. Each vegetative Codiolum phase had a single polyploid nucleus due to endoreduplication, a type of mitosis without nuclear division. 4, 500 ~m ; Figs. 9. A short-cut is described that utilizes a reduced number of preliminary test crosses. Taxonomy and species richness estimates for the genus Caulerpahave proven to be challenging due to the difficulty of assessing morphological species limits. Unique morphological plasticity is observed for several Caulerpa species and provides an added physiological advantage in adaptation to light intensity and temperature changes, as seen for C. racemosa by the variations in form and arrangement of ramuli under different conditions. Highest assimilator height of sea grapes was found in Coron and Culion in Palawan due to higher salinity and temperature while in Mactan, Cebu, it is primarily attributed to lower depth and higher salinity values. Estrada JL, Bautista NS, Dionisio-Sese ML. This article is protected by copyright. Morphology Caulerpa species have a uniaxial siphonous2 thallus mostly divided into a creeping axis (stolon) with rhizoids and erect shoots (fronds) either nude, leaf-like or with grape- or feather-like ramuli. It appears, moreover, thatC. racemosa var.laetevirens are ecophenes (ecads) of a single species. Caulerpa prolifera (Forsskål) J.V.Lamouroux was later designated by Egerod (1952) as the lectotype of the genus. Mylonchulus vasis Yeates, 1992 is reported for the first time from India. These morphological traits, however, can exhibit a high degree of variation under different environmental conditions (Peterson 1972, Calvert 1976, Ohba and Enomoto 1987. Meinesz A; Benichou L; Blachier J; Komatsu T; Lemeé R; Molenaar H; Mari X, 1995. Five Caulerpa species that were previously recorded for Thailand (i.e., C. ambigua, C. cupressoides, C. fastigiata, C. manorensis, and C. mexicana) were not found during our survey (2016-2018) and their identity could not be confirmed with DNA sequence data obtained from herbarium specimens. Morphometric, cluster and principal component analyses showed that morphological plasticity exists in sea grapes species (Caulerpa lentillifera and Caulerpa racemosa) found in different sites in the Philippines. Our results suggest that an event comparable to mitosis occurs before meiosis in the Codiolum phase of M. angicava. Larvae mainly feed by sucking the cell content of green filamentous algae. Anisogamous biflagellate male and female gametes were produced monoeciously and copulated with each other. Water quality monitoring and analysis of plankton, benthos and heavy metals in river Ganga. The present study aimed to identify Caulerpa collections from the northern Philippines aided with DNA barcodes. Although invasive in the temperate regions, Caulerpa species mainly C. racemosa and C. lentillifera (lato) are harvested and consumed as food, especially in the Philippines. All figure content in this area was uploaded by Hideo Ohba, All content in this area was uploaded by Hideo Ohba on Jul 15, 2016, ... Caulerpa species are known to occupy a range of environmental niches that differ significantly with regard to temperature, light availability, water movement, depth, grazing pressure and benthic substrate, ... Characteristics such as phenotypic plasticity, asexual reproduction, surface metabolite production, and nutrient uptake via rhizoids contribute both directly and indirectly to the diverse range of suitable habitats for the genus (Crockett and Keough 2014). IDENTIFICATION: Caulerpa racemosa is a highly variable species. Indeks keragaman Shannon-Wiener (H ') berkisar dari 1,7-2 yang menunjukkan komunitas Caulerpa yang relatif beragam. After this time, the species seemed to disappear, probably because of low winter temperatures. Suitable conservation measures identification along with awreness campaign and developing protected areas. These plants formed primary shoots which differentiated The six species of Caulerpafound in this study are of pantropical in distribution. Caulerpa communities in Solong-on, Siquijor are one of the sources for export to neighbouring municipalities. Primary germ tube formation, after 35 days. Howe from Colaba, Caulerpa racemosa (Forsskal) J. Agardh, Caulerpa racemosa (Forsskal) J.

The variable, as well as the relatively consistent characters are discussed in different populations to assess their role in the diagnosis of species. Elongation of fronds and reduced frond density are commonly observed morphological adaptations that allow for more efficient light uptake with water depth, i.e. 3.2. The species include Clarkus papillatus (Bastian, 1865) Jairajpuri, 1970, Prionchulus muscorum (Dujardin, 1845) Wu & Hoeppli, 1929, Mylonchulus contractus Jairajpuri, 1970, M. hawaiiensis (Cassidy, 1931) AndrÃ¡ssy, The marginal variation observed in the concentration of P and Fe between surface and bottom waters as well as between southern and northern sectors is presumably due to the near fresh water (monsoon) character of the overlying waters during the study period (June 1989) . 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. Our results reduce species richness estimates throughout the ETP by over 54% (from 13 to 6). 2020. Sea grapes, locally known in the Philippines as "lato" or "ar-arusip", are economically important macroalgae belonging to the edible species of the genus Caulerpa. 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. Nomenclatural synonyms. of physicochemical parameters of seawater on their morphology. these new species. 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. Distribution of the Japanese edible alga, Caulerpa lentillifera J. Agardh (Chrolophyceae), was determined by field survey during 2005 to 2011, and observations of its morphology and habitat characteristics were included. We continue the use of ecads as a practical identification tool for morphological diversity below the species level present in the ETP. When assimilator growth did occur, the This book will serve as an authentic field guide and reference material for students, teachers, researchers and policy planners interested in algal resource management, utilization and conservation. 2-3, 10 mm; Fig. Komunitas Caulerpa di Solong-on, Siquijor adalah salah satu sumber untuk ekspor ke kota tetangga. and 5 light intensities (0.5–8.0 klux). by Caulerpa spp. racemosa from the been regarded as an Indian Ocean species immigrated via Mediterranean Sea are distinct taxonomic units. Twenty-three (23) taxa were accounted for among the collec- tions deposited in the University of San Carlos Herbarium (CEBU). 2. This species has an annual life cycle in Lake Utonai, Hokkaido, Japan, hibernating in the 2nd‐4th instar. 40-day-old germling extending a primary germ tube. Caulerpa elongata and C. oligophylla were confirmed occurring in the area for the first time. 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. assess the growth and morphology of cultured Caulerpa species in the field and to determine the effect of key environmental parameters (temperature, light intensity ... Caulerpa spp. Morphology of the specimen was examined, photographed, herbariums prepared and samples preserved in sea water containing 5% formaldehyde. 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. With the addition of species recorded previously but not found during the present study, this brings the total number of Caulerpa species in the region to 15 species. The present study explored the Caulerpa diversity in Thailand for the first time using DNA sequence data (chloroplast-encoded tufA gene and nuclear ITS rDNA sequences) in combination with morphological data. Settled zygotes became spherical and increased in volume. Settled zygotes, 3hr after copulation. Liberation tubes (arrows) on a rhizome. The method should be valuable for identifying newly collected clones, examining potential, interactions among incompatible mating types, and for screening other highly specific inter-organism interactions such as host-parasite infections. C. racemosa is represented by two distinct morphologies in Thailand; a typical C. racemosa morphology (with vesiculate ramuli) and a C. chemnitzia-like morphology (with peltate ramuli). Spherical body after 17 days. 65-day-old germling with two lower thin filaments and one upper thick filament. Male gamete. 14. The peltate form of C. racemosa occurred in sympatry with C. chemnitzia and could not be distinguished from it by morphology. Our lab experiment showed a high tolerance to sedimentation, aided by increased investment in vertical growth. 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. Shannon-Wiener diversity index (H') ranged from 1.7-2 suggesting a relatively diverse Caulerpa community. Protoplasmic network in a fertile assimilator. 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). Morphological variation of two common sea grapes (Caulerpa lentillifera and Caulerpa racemosa) from selected regions in the Philippines. Young larvae are free living without cases, final instar larvae make cases of filamentous algae and some sand particles. 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. Migration study of selected fishes. Collected samples were later sorted to species. Resolving phenotypic plasticity and species designation in the morphology challenging Caulerpa racemosa-peltata complex (Caulerpaceae, Chlorophyta). This study characterized and compared distinct populations of sea grapes from selected regions in the Philippines and described the influence of physicochemical parameters of seawater on their morphology. 5-6, 17, 1 mm ; Figs. This species contains the toxin, caulerpenyn, which may play a role against other organisms such as grazers, epiphytes and competitors. Reproduction and development of C. racemosa var.

Caulerpa mexicana: Partings of rhizoids are very closed on the stolon (1cm). vations at macro scales, however to understand fundamental processes we need to go further using micro, nano and molecular tools. City of San Diego law: It is illegal to possess, sell, and transport any Caulerpa species within city limits. China exported US$1.437 billion worth of raw silk and silk products in the first half of 2004, which was 24.35% higher than the previous year. Wherever it becomes established, it considerably modifies the vegetal communities in the infralittoral zone. Variations in the Structure, Morphology and Biomass of Caulerpa taxifolia in the Mediterranean Sea Fatty Acid Composition of Green Algae of the Genus Caulerpa Impact of UV-A and UV-B Irradiance on the Patterns of Pigments and 15N-Ammonium Assimilation of the Tropical Marine Diatom Bellerochea yucatanensis 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. (Glasby and Gibson, 2007; ... Caulerpa is distributed throughout the tropical and warm temperate waters worldwide (Smith & Walters 1999, Senerpont Domis et al. The protocol used for morphometric analysis in the study was described by, ... Morphometric parameters measured for assimilators, ramuli and rhizoids described by. 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. have also been included. 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. Currently, more than 100 species are recognized worldwide. The first report of a toxic constituent from a seaweed was that of caulerpicin from Caulerpa racemosa by Doty and Aguilar-Santos (1966). Morphological variation of C. racemosa var. A large collection of pressed materials belonging to the marine green algal genus Caulerpa was inventoried. Using a lab experiment, we tested hypotheses about survival and morphological change under different sedimentation regimes. Comparisons are made with similar taxa and characters delimiting. 1958, M. lacustris (Cobb in Cobb, 1915) AndrÃ¡ssy, 1958, M. minor (Cobb, 1893) The typical racemosa, upper right, has short erect branches bearing crowded ramuli with short stalks and oval or spherical tips. 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. Canonical correspondence analysis (CCA) revealed that temperature and type of substrate were the main drivers of Caulerpa biomass. Understanding how species' traits can shape winners and losers of environmental change can help resolve drivers of current community composition patterns and predict future drivers. Morphological variations among 8 species of Caulerpa collected from Gujarat and Maharashtra coast were studied. peltata to various temperatures and light intensities. For easy identification, high resolution colour pictures of each species in its natural habitat together with well spread habit of thallus with cross sections showing characteristic features of respective specimens have been provided. This controversy inhibits the understanding of the diversified life cycles in Ulvophyceae. sertularioides, C. cupressoides, C. serrulata, C. racemosa and C. chemnitzia (part of C. racemosa-peltatacomplex). This study aimed to determine the present standing stock biomass, percent cover and diversity of Caulerpa in Solong-on, as well as to determine the environmental parameters that may affect its abundance and diversity.

However, Mulberry-silk exports slumped 20.83% in volume in the first six months, amounting to 3,676 tons of materials mostly destined for India and Europe. CAULERPA RACEMOSA. Their restriction to the area around the Harbour suggests that they were imported on shipping. 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. Industry sources believe that the world's market conditions favor China's silk exports and China will be able to import more raw cocoons and silk filaments in the second half of 2004. dips of a-axis of clasts with longer a-axis length have to be measured in order to gain a stronger fabric in periglacial slope deposits. In addition, b/a-axis ratio less than 0.55 must be included in criteria of clast selection under the conditions with full investigating time. However, the nuclear behavior in the Codiolum phases is largely unknown, probably because no suitable methods are available. In addition we formally recognize the synonymy ofC. 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). Morphometric, cluster and principal component analyses showed that morphological plasticity exists in sea grapes species (Caulerpa lentillifera and Caulerpa racemosa) found in different sites in the Philippines. There was no change in the morphology of either growth-form when cultured through a range of salinity (10-40%o) and light (20-140 -1) conditions. 2014. accounted for US$1.195 billion of gross turnover alongwith United States. All rights reserved. The toxin accumulated by fish which eat Caulerpa can render them unsuitable for human consumption. In the field, C. filiformis fronds were more elongated and less branched when a sediment veneer is present and when water depth increased (i.e. All three new taxa have three different kinds of external areolar patterns, confirming the presence of three different groups of Gomphonema in one habitat.
