Distribution of seagrasses from 529 sites in the Philippines from 1983 to 2012. Studies suggest that Halophila ovalis can recover rapidly from grazing by dugong. Distribution and Biomass of Halophila ovalis (R.Brown) Hook. Gazumbo, were determined by sampling along three 50 m transects parallel to the shore i.e. Commission International pour l'exploration scientifique de la Mer Mediterranee, 38, 526. Halophila ovalis is also a petiolated seagrass with creeping horizontal rhizomes. Halophila ovalis occupied 550–600 ha in the lower reaches of the estuary, approximately 20% of the area of the main estuarine basin. 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).

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). The biomass, productivity and biometry of Halophila ovalis were strongly influenced by salinity, temperature and light supply. Hook.f. 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. updated: Dec 11th 2020, 4:01 pm see all updates 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 nearshore, Hook f. is the dominant benthic plant of the Swan/Canning Estuary, southwestern Australia.

Sort by Weight Alphabetically such as Indo-West Pacific. Fl. 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. The species name Halophila ovata is now regarded as a synonym of this species.[1].

Distribution in the main estuarine basin differed little between 1976 and 1982, although the species was more ephemeral in the Canning Estuary. 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 Plants Database includes the following 8 species of Halophila . Previous phylogenetic studies found no or little sequence divergence among morphologically distinct species of Halophila 51, 1-2, 1-54. 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. Individual leaves grow to about 4" with a rhizome of up to 2 ft long. Hook f. is the dominant benthic plant of the Swan/Canning Estuary, southwestern Australia. ; At least three species of sea urchins were found in the meadow. Larger fragments, e.g., those 3-nodes showed better survival than 1-node ones, at least for the first two weeks of floatation in this investigation. - "A Taxonomic Study of the Seagrass Genus Halophila (Hydrocharitaceae) from Japan: Description of a New Species Halophila japonica sp.
