Global seagrass habitats are threatened by multiple anthropogenic factors. Effective management of seagrasses requires information on the relative impacts threats; however, this is rarely available. Our goal was to use knowledge experts assess activities in six global bioregions. The that threaten were identified at an international workshop and followed with a web-based survey collect vulnerability information. There consensus urban/industrial runoff, urban/port infrastructure development,...
In coastal areas around the world, dominant primary producers are benthic macrophytes, including seagrasses and macroalgae, that provide habitat structure food for diverse abundant populations communities, drive ecosystem processes. Seagrass meadows macroalgal forests economically central to human particularly in developing contributing fisheries yield, storm protection, blue carbon storage, important cultural values. These services threatened worldwide by activities, with substantial of...
Concern over the loss of seagrass habitat has prompted examination value production commercial prawns from such habitat. Cairns Harbour in tropical northern Queensland 876 ha mixed seagrasses, dominated by Zostera capricorni and Halodule pinifolia, that support a multispecies penaeid prawn fishery offshore. Densities juvenile estimated surveys were used to project estimates annual yield landed value, using deterministic simulation model employing lunar-period time steps. Estimates potential...
From aerial photography (July 1987) and diving surveys (February 1988), 876 ha of seagrasses (eight species) were mapped in Cairns Harbour, tropical north-eastern Queensland. Zostera capricorni was the most common seagrass species had greatest biomass at 79 g m-2 dry weight stems leaves 180 roots rhizomes. The maximum shoot density found 4798 shoots Halodule pinifolia, second species. Seagrasses only between 0.5 5.0 m below mean sea level. shallowest depths, pinifolia deepest depths. Twenty...
The area of seagrasses in waters adjacent to the Queensland coast between Cape York and Hervey Bay is approximately 4000 km2. Seagrasses were found near estuaries, coastal bays associated with islands, at sites that provided shelter from south-easterly trade winds Pacific Ocean swells. Of seagrass meadows mapped, 37% had a bottom vegetation cover greater than 50%. Two large continuous areas (total 2500 km2) predominantly Halophila species deep water Barrow Point Lookout may be part much...
Abstract Maintaining ecological processes that underpin the functioning of marine ecosystems requires planning and management resources at an appropriate spatial scale. The Great Barrier Reef World Heritage Area (GBR) is world's largest (approximately 348 000 km 2 ) second protected area. It difficult to inform scale because high cost associated with collecting data. To address this coastal 15 m below mean sea level) habitats GBR, study determined presence distribution seagrass by generating...
Abstract Terrestrial plants use an array of animals as vectors for dispersal, however little is known biotic dispersal marine angiosperms such seagrasses. Our study in the Great Barrier Reef confirms first time that dugongs ( Dugong dugon ) and green sea turtles Chelonia mydas assist seagrass dispersal. We demonstrate these mega-herbivores consume pass faecal matter viable seeds at least three species Zostera muelleri , Halodule uninervis Halophila decipiens ). One to two per g DW were found...
Thirteen species of seagrass and six juvenile penaeid prawn commercial importance were found in beds waters between Cape York Cairns. The pioneering species, Halodule uninemis (Forsk.) Aschers, Halophila ovalis (R. Br.) Hook. f., present almost all coastal areas. Two often dominant the tropics, Enhalus acoroides (L.f.) Royle Thalassia hemprichii (Ehrenb.) Aschers., uncommon. This is likely to have resulted from environmental stress during periods reduced salinity high turbidity associated...
