Central Eastern Shelf Transition
Tweed–Moreton, also known as the Central Eastern Shelf Transition, is a marine biogeographic region of eastern Australia. The region includes the coastal and estuarine waters from just north of the Baffle Creek estuary in Queensland to north of Nambucca Heads in New South Wales. It extends from the shore to the edge of the narrow continental shelf,Thackway R, Cresswell ID. 1998.

IMCRA 4
The Integrated Marine and Coastal Regionalisation of Australia (IMCRA), formerly the Interim Marine and Coastal Regionalisation for Australia, is a biogeography, biogeographic regionalisation of the oceanic waters of Australia's exclusive economic zone (EEZ). As of 2008, the most recent version is IMCRA Version 4.0. IMCRA actually defines two bioregionalisations: a benthic bioregionalisation, based on biogeography of fish together with geophysics, geophysical data; and a pelagic bioregionalisation, base on oceanography, oceanographic characteristics. The benthic bioregionalisation incorporates three separate regionalisations: #A regionalisation of the EEZ into provincial bioregions, based on the biogeography of bottom dwelling fishes. In IMCRA 4.0, 41 provincial bioregions, consisting of 24 ''provinces'' and 17 ''transitions''. #A regionalisation of the continental shelf into ''meso-scale regions'' based on biological and physical characters, and the distance from the coast.

Ecoregions Of Australia
Ecoregions in Australia are geographically distinct plant and animal communities, defined by the World Wide Fund for Nature based on geology, soils, climate, and predominant vegetation. The World Wide Fund for Nature (WWF) identified 825 terrestrial ecoregions that cover the Earth's land surface, 40 of which cover Australia and its dependent islands. The WWF ecoregions are classified by biome type (tropical and subtropical moist broadleaf forests, temperate grasslands, savannas, and shrublands, tundra, etc.), and into one of eight terrestrial realms. Australia, together with New Zealand, New Guinea and neighboring island groups, is part of the Australasian realm. The IBRA bioregions informed the delineation of the WWF ecoregions for Australia, and the WWF ecoregions generally follow the same ecoregion boundaries, while often clustering two or more similar bioregions into a larger ecoregion. The ecoregion articles in Wikipedia generally follow the WWF scheme. The WWF ecoregions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Ecoregions
A marine ecoregion is an ecoregion, or ecological region, of the oceans and seas identified and defined based on biogeographic characteristics. Introduction A more complete definition describes them as “Areas of relatively homogeneous species composition, clearly distinct from adjacent systems” dominated by “a small number of ecosystems and/or a distinct suite of oceanographic or topographic features”. Ecologically they “are strongly cohesive units, sufficiently large to encompass ecological or life history processes for most sedentary species.”Spalding, Mark D., Helen E. Fox, Gerald R.

Moreton Bay Marine Park
The Moreton Bay Marine Park was established in 1992 to protect ecologically significant habitats in Moreton Bay. The marine park extends from Caloundra south to the southern tip of South Stradbroke Island. The marine park's border extends up to the highest tidal mark and covers a total of 3,400 km2. The marine park provides protection to sensitive reef sites near Tangalooma and Flinders Reef. It includes waterways such as Coombabah Lake, sheltered inlets, open ocean, mangrove forests, swamps, marshes, tidal mudflats, sandflats and seagrass beds. It is a temporary home to migrating shorebirds that inhabit wetlands. Dugongs, whales and turtles swim in the waters of the bay. Six of the world's seven species of sea turtles habitat the park. The marine park is managed by the Queensland Parks and Wildlife Service. In 1971, a total of 18 countries signed a Convention on Wetlands of International Significance.

Bivalve
Bivalvia (), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. As a group, bivalves have no head and they lack some usual molluscan organs, like the radula and the odontophore. They include the clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into ctenidia, specialised organs for feeding and breathing. Most bivalves bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other hard surfaces. Some bivalves, such as the scallops and file shells, can swim. The shipworms bore into wood, clay, or stone and live inside these substances. The shell of a bivalve is composed of calc ...

Hermatypic Coral
Hermatypic corals are those corals in the order Scleractinia which build reefs by depositing hard calcareous material for their skeletons, forming the stony framework of the reef. Corals that do not contribute to coral reef development are referred to as ahermatypic (non-reef-building) species. Many reef-forming corals contain symbiotic photosynthetic zooxanthella Zooxanthellae is a colloquial term for single-celled dinoflagellates that are able to live in symbiosis with diverse marine invertebrates including demosponges, corals, jellyfish, and nudibranchs. Most known zooxanthellae are in the genus '' Sym ...e, which contribute to their nutritional needs. The term "hermatypic" is sometimes misused, being assumed to apply to all zooxanthellate corals. However, there are zooxanthellae in many non reef-forming corals; and not all hermatypic corals in shallow water contain zooxanthellae. Further, some hermatypic corals live at depths to which light cannot penetrate; they form deep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echinoderm
An echinoderm () is any member of the phylum Echinodermata (). The adults are recognisable by their (usually five-point) radial symmetry, and include starfish, brittle stars, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or "stone lilies". Adult echinoderms are found on the sea bed at every ocean depth, from the intertidal zone to the abyssal zone. The phylum contains about 7,000 living species, making it the second-largest grouping of deuterostomes, after the chordates. Echinoderms are the largest entirely marine phylum. The first definitive echinoderms appeared near the start of the Cambrian. The echinoderms are important both ecologically and geologically. Ecologically, there are few other groupings so abundant in the biotic desert of the deep sea, as well as shallower oceans. Most echinoderms are able to reproduce asexually and regenerate tissue, organs, and limbs; in some cases, they can undergo complete regeneration from a single limb. ...
