distribution and abundance. Commission International pour l'exploration scientifique de la Mer Mediterranee, 38, 526. It occurs on Pacific Islands such as Fiji. Over 99% of the seagrass was in water less than 2 m deep (relative to “datum”, an extreme low water reference mark set in 1892). Distribution and Biomass of Halophila ovalis (R. Brown) Hook. f., which is the most common seagrass species that can be found in the tropical waters Click below on a thumbnail map or name for species profiles. 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. Report for Halophila ovalis (R.Br.) such as Indo-West Pacific. Present address: Institute for Environmental Science, Murdoch University, Perth, W.A. Halophila ovalis, commonly known as paddle weed, spoon grass or dugong grass, is a seagrass in the family Hydrocharitaceae. The seagrass Halophila ovalis (R.Br.) The distribution of intertidal seagrass meadows was certainly constrained by the surface water turbidity. ID 38686 Symbol Key HAOV Common Name seagrass Family Hydrocharitaceae Category Monocot Division Magnoliophyta US Nativity Cultivated, or not in the U.S. US/NA Plant Yes State Distribution N/A Growth Habit N/A Flowers and fruit of the seagrass Halophila ovalis subsp. ; At least three species of sea urchins were found in the meadow. Wetland Status. Over 99% of the seagrass was in water less than 2 m deep (relative to “datum”, an extreme low water reference mark set in 1892). Abstract. The distribution of intertidal seagrass meadows was certainly constrained by the surface water turbidity. 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). The number of its contained species, and its own placement in the order Alismatales, has evolved.. 6150, Australia. Together they form a unique fingerprint. H. ovalis and H. minor are recorded for Singapore. Halophila ovalis has very limited capacity to disperse by sea, as indicated by the short duration of various life history stages that remain floating and alive (Table 2). Hook f. is the dominant benthic plant of the Swan/Canning Estuary, southwestern Australia. Br.) 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. Hook f. is the dominant benthic plant of the Swan/Canning Estuary, southwestern Australia. These results were incorporated into a model to determine how much of the variance in productivity could be accounted for by these three factors, assuming independent action. Halophila ovalis grew actively at salinities from approximately 10 to 40‰. The highest observed growth rate, approximately 2.1 mg DW per apex day−1, was reached at 25°C. Average productivity was 500 g C m−2 year−1, although uniform stands in shallow waters attained up to 1200 g C m−2 year−1. 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 of this genus . and B. Morton, 1978. The leaves are ovate in outline, appearing on stems that emerge from rhizome beneath the sand. ©Anne Hoggett: Halophila ovalis … Studies suggest that Halophila ovalis can recover rapidly from grazing by dugong. 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; The arrangement of the plant, above and below ground, provides stability to the sea floor and habitat for other species.
