Leaves in pairs, subtended by bracts; petiole 1-3 cm long; lamina variable in shape and size, linear to lanceolate or ovate ('racquet-shaped'), 10-15 mm long and 2-8 mm wide, green often with brown transverse lines, apex acute, or rounded, base attenuate or rounded. 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. The distribution, biomass and primary production of the seagrass. Distribution of seagrasses from 529 sites in the Philippines from 1983 to 2012. Distribution of seagrasses from 529 sites in the Philippines from 1983 to 2012. The distribution, biomass and primary production of the seagrass Halophila ovalis in the Swan/Canning Estuary, Western Australia. The model was relatively successful at predicting seasonal growth responses, but underestimated spring productivity, probably because the unpredictable light climate in spring in the Swan River was not fully simulated. 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‰). Report for Halophila ovalis (R.Br.) Hook f. is the dominant benthic plant of the Swan/Canning Estuary, southwestern Australia. 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- The roots get up to 800 mm long and covered in fine root hairs. The seagrass leaf provides a … 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. 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. Click below on a thumbnail map or name for species profiles. Wetland Status. Halophila ovalis was found at: View larger distribution map. ©Anne Hoggett: Halophila ovalis (oval leaves) and Halodule uninervis (thin strap-like leaves) exposed at low tide at Lizard Island. ©Anne Hoggett: Halophila ovalis … 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. The effects of salinity, temperature and light were investigated by growing sprigs in artificial seawater culture and measuring growth increments. Abstract. Rhizomes long, branching; internodes about 2-4 cm long, light yellow, thin, brittle. Hook f. is the dominant benthic plant of the Swan/Canning Estuary, southwestern Australia. Br.) 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 species name Halophila ovata is now regarded as a synonym of this species.[1]. It occurs on Pacific Islands such as Fiji. 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. 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. 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). White sand, mud. It is a small herbaceous plant that occurs in sea beds and other saltwater environments in the Indo-Pacific. The seagrass Halophila ovalis (R.Br.) Aquat. Studies suggest that Halophila ovalis can recover rapidly from grazing by dugong. 3f ). Brief Description Grazyna Paczkowska, Tuesday 9 August 1994. Diversity and distribution of macrophytes along the coast of Lebanon (Levantine Basin, Eastern Mediterranean). Br.) 1. J.D.
