Copyright © 1995 Published by Elsevier B.V. https://doi.org/10.1016/0304-3770(95)00466-D. Leaf blade 18.20-31.45 mm … Hook f. is the dominant benthic plant of the Swan/Canning Estuary, southwestern Australia. Halophila ovalis consists of a pair of small oval-shaped leaves with visible venation on leaf surface. This paper describes the biomass, distribution and primary production of this plant in relation to environmental factors.Halophila ovalis occupied 550-600 ha in the lower reaches of the estuary, approximately 20% of the area of the main estuarine basin. Distribution and Biomass of Halophila ovalis (R. Brown) Hook. f. at Pulau Gazumbo, Penang, Straits of Malacca We use cookies to help provide and enhance our service and tailor content and ads. Br.) The first description of the species was by Robert Brown as Caulinia ovalis, this was transferred to the genus Halophila by Joseph Dalton Hooker in Flora Tasmaniae (1858). J.D. The biomass, productivity and biometry of Halophila ovalis were strongly influenced by salinity, temperature and light supply. H. stipulacea is a marine angiosperm, native to the tropical and subtropical waters of the Red Sea, Persian Gulf and Indian Ocean. Distribution by Station: DA3/99/37 — Off W side of Malus Islands; DA3/99/41 — S of Norbill Bay, NE of Georgeff Reefs; DA3/99/44 — SE of Gordon Point, Rosemary Island; Aquatic Botany, 1, 203-215. Field and laboratory studies indicated that during years of average river discharge (1980, 1982), Halophila ovalis was little affected by the salinity range experienced (15–35‰). Aquat. 26. Halophila ovalis grew actively at salinities from approximately 10 to 40‰. Dioecious. 3f ). The highest observed growth rate, approximately 2.1 mg DW per apex day−1, was reached at 25°C. However, during 1981, a year of high discharge, conditions of low salinity and poor light supply caused severe declines in biomass, particularly in the Canning Estuary. In the study area, H. ovalis was found in the tidal flat of the intertidal zone and the clay-like and arenaceous parts of subtidal zones (Shi et al. Fig. Copyright © 2020 Elsevier B.V. or its licensors or contributors. We assessed the impact of boat anchors from traditional fishing and recreational activities on the seagrass Halophila ovalis from the Andaman and Nicobar Isalnds of India. Sort by Weight Alphabetically H. ovalis and H. minor are recorded for Singapore. https://en.wikipedia.org/w/index.php?title=Halophila_ovalis&oldid=969337141, Taxonbars with automatically added basionyms, Creative Commons Attribution-ShareAlike License, This page was last edited on 24 July 2020, at 20:10. - "A Taxonomic Study of the Seagrass Genus Halophila (Hydrocharitaceae) from Japan: Description of a New Species Halophila japonica sp. Hook f. is the dominant benthic plant of the Swan/Canning Estuary, southwestern Australia. Sea grasses such as Thalassia hempirichii, Halophila ovalis and Halodule uninervis were collected from the The most ubiquitous species is Halophila ovalis, which can be found at 29 of the 32 locations where seagrass is present, followed by Enhalus acoroides (24 of the 32 locations). Abstract. Aug to Dec or Jan to Apr. The plants grow from a single rhizome and prefer shallow, calm protected habitats but can be found as deep as 80 feet. Distribution by Station: DA3/99/37 — Off W side of Malus Islands; DA3/99/41 — S of Norbill Bay, NE of Georgeff Reefs; DA3/99/44 — SE of Gordon Point, Rosemary Island; Gazumbo, were determined by sampling along three 50 m transects parallel to the shore i.e. By continuing you agree to the use of cookies. Halophila ovalis in the Tropical Atlantic Ocean ... Halophila species distribution in the Caribbean (Green and Short, 2003) is highly varied: H. decipiens and H. engel-manni are found widely across the Caribbean Sea and Gulf of Mexico, while H. baillonii has an infrequent, discontinuous distri- Halophila — ID 38677 Symbol Key HALOP Common Name seagrass Family Hydrocharitaceae Category Monocot Division Magnoliophyta US Nativity N/A US/NA Plant Yes State Distribution FL, HI, LA, MS, PR, TX, VI Growth Habit N/A … Wetland Status.

Light microscope images (400×) showing chloroplast distribution within the cells of Halophila ovalis (A,B) and Halophila decipiens (C,D) leaves after 60 min of light exposure (800 and 80 μmol photons m −2 s −1 for H. ovalis and H. decipiens, respectively). Key to the marine taxa of Cymodoceaceae in the Philippines 1. leaves subulate or terete, flowers a cymose inflorescence ... Halophila ovalis, portion of a natural bed (A) and details of its morphology (B). This paper describes the biomass, distribution and primary production of this plant in relation to environmental factors. The distribution of intertidal seagrass meadows was certainly constrained by the surface water turbidity. Dioecious. Using phylogenetic analyses of the nuclear ribosomal internal transcribed spacer (ITS1-5.8S-ITS2) region showed that some specimens identified as H. ovalis belonged to different clades, and this clearly points out the need for critical taxonomic revision of Halophila material from the entire geographic distribution … The leaves are ovate in outline, appearing on stems that emerge from rhizome beneath the sand. Fl. Hooker, 1858. Halophila ovalis (R. Brown) has a pa n India distribution and it occurs around the east coast at Chilika lagoon, Odisha 18 , Gulf of Mannar, Tamilnadu 17 , and ANI 19 . Hook.f. Fig. Aquatic Botany. Halophila ovalis was found at: View larger distribution map. Two petioles attached to the node are almost equal in length, ranged 14.20-35.90 mm. Halophila species (H. ovalis, H. stipulacea, H. spinulosa) had already been described under other genera as Zostera stipulacea [13], Caulinia ovalis and C. spinulosa [14]. This paper describes the biomass, distribution and primary production of this plant in relation to environmental factors. It is a small herbaceous plant that occurs in sea beds and other saltwater environments in the Indo-Pacific. Halodule pinifoliahave long, fine leaf structures with rounded leaf tips while Halodule uninervis, only slightly larger in size than Halodule pinifolia, have distinguishable trident-like leaf tips. Halophila ovalis(R. Brown) Hook. f. – seagrass Subordinate Taxa. Fl. Distribution of seagrasses from 529 sites in the Philippines from 1983 to 2012. Uniform stands of Halophila ovalis reached a biomass of up to 120 g dry weight (DW) m−2 in late summer/early autumn, and maximum productivities of up to 40 g DW m−2 day−1 in summer. Halophila johnsonii, a species on the U.S. Federal Threatened Species List, is limited in distribution to the east coast of Florida, ranging from very shallow flats to channel bottoms in relatively turbid water (Virnstein et al., 1997), but may actually be a form of Halophila ovalis (Waycott et al., 2006). Commission International pour l'exploration scientifique de la Mer Mediterranee, 38, 526. Based on the results of research in the Waters of Soop Island there are 7 types of seagrass, namely syringodium isoetifolium, Thalassia hemprici, Cymodocea serrulate, Thalassodendron ciliatum, Halophila ovalis, Enhalus acoroides and Halodule uninervis. Hook f. is the dominant benthic plant of the Swan/Canning Estuary, southwestern Australia. such as Indo-West Pacific. Th e distribution of Halophila ovalis is confind to . Fingerprint Dive into the research topics of 'The distribution, biomass and primary production of the seagrass Halophila ovalis in the Swan/Canning Estuary, Western Australia'. The species that occur least frequently are Halodule pinifolia, Halophila decipiens, and Halophila minor. Halophila ovalis, commonly known as paddle weed, spoon grass or dugong grass, is a seagrass in the family Hydrocharitaceae.
