Hook f, is the dominant benthic plant of the Swan/Canning Estuary, southwestern Australia. White sand, mud. Brief Description Grazyna Paczkowska, Tuesday 9 August 1994. 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). Rhizomes up to 1.57 mm in diameter with a single root at each node ( Fig. Br.) 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]. Distribution of seagrasses from 529 sites in the Philippines from 1983 to 2012. 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. This is a common plant of the sublittoral zone in its range, growing in depths up to 20 meters in lagoons, on reefs, and in many other types of marine habitat just offshore. Map of Japan showing distribution of Halophila japonica ( ) and H. ovalis ( ) based on recent fieldcollections and herbarium specimens. The distribution and biomass of Halophila ovalis, the dominant seagrass species in Pulau. The seagrass genus Halophila Thouars has more than twenty described species and is predominately distributed over a wide geographic range along the tropical and the warm temperate coastlines in the Indo-West Pacific Oceans. Hooker, 1858. Report for Halophila ovalis (R.Br.) Light was considered the more important factor controlling growth, since the waters of the estuary are generally turbid, and subject to sudden increases in turbidity. Distribution of seagrasses from 529 sites in the Philippines from 1983 to 2012. 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. nearshore, It is used as food by dugong, as is therefore known as dugong grass. Family: Hydrocharitaceae. Halophila ovalis(R. Brown) Hook. 1. - "A Taxonomic Study of the Seagrass Genus Halophila (Hydrocharitaceae) from Japan: Description of a New Species Halophila japonica sp. 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. Wetland Status. and B. Morton, 1978. 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 . ; At least three species of sea urchins were found in the meadow. Distribution in the main estuarine basin differed little between 1976 and 1982, although the species was more ephemeral in the Canning Estuary. Studies suggest that Halophila ovalis can recover rapidly from grazing by dugong. Br.) It is a small herbaceous plant that occurs in sea beds and other saltwater environments in the Indo-Pacific. Halophila ovalis, commonly known as paddle weed, spoon grass or dugong grass, is a seagrass in the family Hydrocharitaceae.

Hook. The distribution, biomass and primary production of the seagrass Halophila ovalis in the Swan/Canning Estuary, Western Australia. Lipkin Y, 1975a. Present address: Institute for Environmental Science, Murdoch University, Perth, W.A. Click below on a thumbnail map or name for species profiles. Th e distribution of Halophila ovalis is confind to . The distribution and biomass of Halophila ovalis, the dominant seagrass species in Pulau Gazumbo, were determined by sampling along three 50 m transects parallel to the shore i.e. Distribution and Biomass of Halophila ovalis (R.Brown) Hook. 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. The seagrass Halophila ovalis (R.Br.) Distribution and habitat. 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). 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. Halophila ovalis is a beautiful species of sea grass native to Asia and the South Pacific. Halophila ovalis. Two petioles attached to the node are almost equal in length, ranged 14.20-35.90 mm. The distribution of intertidal seagrass meadows was certainly constrained by the surface water turbidity. Productivity increased from 15 to 20°C by a factor of seven, and a further 30% from 20 to 25°C. 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; Species in Pulau sites in the main estuarine basin differed little between 1976 and 1982, although the species more!
