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- Hooker, 1858. Halophila_ovalis - WikiMili, The Free Encyclopedia 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‰). Hook. Halophila ovalis occupied 550–600 ha in the lower reaches of the estuary, approximately 20% of the area of the main estuarine basin. It is commonly referred to a spoon grass or paddle weed. Previous phylogenetic studies found no or little sequence divergence among morphologically distinct species of Halophila The distribution and biomass of Halophila ovalis, the dominant seagrass species in Pulau. 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. 1. Wetland Status. 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). 2010). Lipkin Y, 1975a. Sites are similar in species composition and abundance. bullosa (Setchell) Hartog are reported from the Nasese intertidal flats, Laucala Bay, Fiji Islands, and described for the first time. Distribution in the main estuarine basin differed little between 1976 and 1982, although the species was more ephemeral in the Canning Estuary. Each factor was investigated separately; salinity values ranged from 5 to 45‰, temperature from 10 to 25°C and light from 0 to 400 μE m−2 s−1. Our study … The Plants Database includes the following 8 species of Halophila . The distribution, biomass and primary production of the seagrass Halophila ovalis in the Swan/Canning Estuary, Western Australia. Hook f. is the dominant benthic plant of the Swan/Canning Estuary, southwestern Australia. 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. It is used as food by dugong, as is therefore known as dugong grass. 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. Flowers and fruit of the seagrass Halophila ovalis subsp. The highest observed growth rate, approximately 2.1 mg DW per apex day−1, was reached at 25°C. The main growing period was summer, when marine salinities prevailed, and light supply and temperature were highest. Distribution and habitat. Seagrass ecosystems are lost due to habitat disturbance, coastal development and human pressure.
