The seagrass Halophila ovalis (R.Br.) Rhizomatous, dioecious, submerged, marine or estuarine perennial, herb. 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. The species that occur least frequently are Halodule pinifolia, Halophila decipiens, and Halophila minor. The highest observed growth rate, approximately 2.1 mg DW per apex day−1, was reached at 25°C. 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). Th e distribution of Halophila ovalis is confind to . 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). Brief Description Grazyna Paczkowska, Tuesday 9 August 1994. The seagrass Halophila ovalis (R.Br.) This paper describes the biomass, distribution and primary production of this plant in relation to environmental factors. Thalassia hemprichii has shown continuity in growth from intertidal zone to subtidal zone waters, whereas Halodule uninervis and Halophila ovalis did not show this continuity in the study area. 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). 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). The effects of salinity, temperature and light were investigated by growing sprigs in artificial seawater culture and measuring growth increments. The seagrass Halophila ovalis (R.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). Halophila ovalis. J.D. 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 plant occurs around reefs, estuaries, islands, inter-tidal areas, on soft sand or mud substrates. Studies suggest that Halophila ovalis can recover rapidly from grazing by dugong. Enhalus acoroides, Cymodocea rotundata, Halodule uninervis, Halophila ovalis and Thalassia hemprichii dominated the approximately 500 m seagrass bed in the area. 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. 2010). Sea grasses such as Thalassia hempirichii, Halophila ovalis and Halodule uninervis were collected from the 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. 1. The species that occur least frequently are Halodule pinifolia, Halophila decipiens, and Halophila minor. The main growing period was summer, when marine salinities prevailed, and light supply and temperature were highest. The biomass, productivity and biometry of Halophila ovalis were strongly influenced by salinity, temperature and light supply. f. at Pulau Gazumbo, Penang, Straits of Malacca The arrangement of the plant, above and below ground, provides stability to the sea floor and habitat for other species. distribution and abundance.
