Fl. - "A Taxonomic Study of the Seagrass Genus Halophila (Hydrocharitaceae) from Japan: Description of a New Species Halophila japonica sp. 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. Seagrass ecosystems are lost due to habitat disturbance, coastal development and human pressure. Map of Japan showing distribution of Halophila japonica ( ) and H. ovalis ( ) based on recent fieldcollections and herbarium specimens. Hook. The main growing period was summer, when marine salinities prevailed, and light supply and temperature were highest. 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. Figure 13. 3f ). 9: Hodgkiss, I.J. Bot., 51: 1-54. Hook f. is the dominant benthic plant of the Swan/Canning Estuary, southwestern Australia. 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). Salinity, temperature and light were lowest during winter. Previous phylogenetic studies found no or little sequence divergence among morphologically distinct species of Halophila H. ovalis and H. minor are recorded for Singapore. The distribution of intertidal seagrass meadows was certainly constrained by the surface water turbidity. Studies suggest that Halophila ovalis can recover rapidly from grazing by dugong. 51, 1-2, 1-54. 1. The number of its contained species, and its own placement in the order Alismatales, has evolved.. It is often found in meadows that dominate a sand bank or other patch of sea floor. The distribution, biomass and primary production of the seagrass Halophila ovalis in the Swan/Canning Estuary, Western Australia. Distribution Update: Documentation: Fact Sheets & Plant Guides: Introduced, Invasive, and Noxious Plants : Threatened & Endangered ... Halophila ovalis (R. Br.) 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 . Role in the habitat: This seagrass is among the favourite food of dugongs so it is also sometimes called Dugong grass.

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. The most common areas of .

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.
