The Southeast Shelf Transition is a biogeographic region of Australia's coastal and continental shelf waters. It covers a portion of Australia's southeastern coast, from southern New South Wales to eastern Victoria, including the islands of the Kent Group and Furneaux Group at the eastern end of the Bass Strait. It is a provincial level bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system, and is a transitional region between the warm temperate Central Eastern Shelf Province to the northeast and the cool temperate Bass Strait Shelf and Tasmanian Shelf provinces to the west and south. [1] It corresponds to the Cape Howe marine ecoregion in the WWF's Marine Ecoregions of the World system. [2]
The Southeast Shelf Province extends along Australia's southeastern coast from south of Wollongong in New South Wales to Wilsons Promontory in Victoria, and south to Cape Portland at Tasmania's northeastern tip, enclosing the Furneaux and Kent groups of islands at the eastern end of the Bass Strait. It adjoins the Bass Strait Shelf Province on the southwest, and the Tasmanian Shelf Province on the south. On the east it extends to the edge of the continental shelf. [3]
The transition marks the southernmost influence of the warm East Australian Current, which brings warmer water as far as the eastern Bass Strait. [3]
The province contains three meso-scale bioregions: [3] [1]
The biota of the bioregion is dominated by warm temperate species characteristic of the Central Eastern Province, with a smaller number of cool-temperate species from the Bass Strait Shelf and Tasmanian provinces, and a few tropical species from the Northeast Shelf Province. There is a major disjunction of species' ranges at Cape Howe, which marks the southernmost range of several warm water species and the northern extent of several cold temperate species. [3]
The Nearctic realm is one of the eight biogeographic realms constituting the Earth's land surface.
The Bass Strait Shelf Province is a biogeographic region of Australia's coastal and continental shelf waters. It covers the central Bass Strait between Tasmania and the southern Australian mainland. It is a provincial level bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system. The Bassian and adjacent Tasmanian Shelf provinces correspond to the Bassian marine ecoregion in the WWF's Marine Ecoregions of the World system.
The Central Eastern Shelf Province is a biogeographic region of Australia's coastal and continental shelf waters. It includes the warm temperate coastal waters of eastern Australia. It is a provincial level bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system. It corresponds to the Manning-Hawkesbury marine ecoregion in the WWF's Marine Ecoregions of the World system.
Tweed–Moreton, also known as the Central Eastern Shelf Transition, is a marine biogeographic region of eastern Australia.
The Central Western Shelf Province, also known as the Shark Bay marine ecoregion, is a biogeographic region of Australia's continental shelf and coastal waters. It includes the subtropical coastal waters of Western Australia.
The Northeast Shelf Province is a biogeographic region of Australia's coastal and continental shelf waters. It includes the tropical coastal waters of the central and southern Great Barrier Reef in northeastern Australia. It is a provincial level bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system. It corresponds to the Central and Southern Great Barrier Reef marine ecoregion in the WWF's Marine Ecoregions of the World system.
The Northeast Shelf Transition is a biogeographic region of Australia's coastal and continental shelf waters. It includes the tropical coastal waters of the northern Great Barrier Reef and the Torres Strait in northeastern-most Australia. It is a provincial level bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system. It corresponds to the Torres Strait and Northern Great Barrier Reef marine ecoregion in the WWF's Marine Ecoregions of the World system.
The Northern Shelf Province, also known as Arnhem Coast to Gulf of Carpentaria, is a biogeographic region of Australia's continental shelf. It includes the coastal waters of Arnhem Land and the Gulf of Carpentaria in Northern Australia.
The Northwest Shelf Province, also known as Exmouth to Broome, is a biogeographic region of Australia's continental shelf.
The Northwest Shelf Transition, also known as Bonaparte Coast, is a biogeographic region of Australia's continental shelf. It adjoins the Kimberley region of Western Australia and the adjacent coast of the Northern Territory.
The Southwest Shelf Province, also known as the Leeuwin marine ecoregion, is a biogeographic region of Australia's continental shelf. It includes the temperate coastal waters of Southwest Australia.
The Southwest Shelf Transition, also known as the Houtman marine ecoregion, is a biogeographic region of Australia's continental shelf and coastal waters. It includes the subtropical coastal waters of Southwest Australia.
The Spencer Gulf Shelf Province, also known as the South Australian Gulfs marine ecoregion, is a biogeographic region of Australia's continental shelf and coastal waters. It includes the warm temperate coastal waters of South Australia's central coast. It is a provincial bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system.
The Tasmanian Shelf Province is a biogeographic region of Tasmania's coastal and continental shelf waters. It covers the western, eastern, and southern coasts of Tasmania. It is a provincial level bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system. The Tasmanian Shelf and adjacent Bass Strait Shelf provinces correspond to the Bassian marine ecoregion in the WWF's Marine Ecoregions of the World system.
The Western Bass Strait Shelf Transition is a biogeographic region of Australia's coastal and continental shelf waters. It is a transitional region between the cold-temperate Bass Strait Shelf and Tasmanian Shelf provinces and the warm-temperate Spencer Gulf Shelf Province. It is a provincial bioregion in the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system. It is the southern portion of the Western Bassian marine ecoregion in the World Wildlife Fund's (WWF) Marine Ecoregions of the World system.
Temperate Southern Africa is a biogeographic region of the Earth's seas, comprising the temperate waters of southern Africa, where the Atlantic Ocean and Indian Ocean meet. It includes the coast of South Africa and Namibia, and reaches into southern Angola. It also includes the remote islands of Amsterdam and Saint-Paul, to the east in the southern Indian Ocean.
Temperate Australasia is a biogeographic region of the Earth's seas, comprising the temperate and subtropical waters of Australia and New Zealand, including both the Indian Ocean and Pacific coasts of the continent and adjacent islands.
The Bassian ecoregion is a biogeographic region of Australia's coastal and continental shelf waters. It includes the cold-temperate waters surrounding Tasmania, including the central Bass Strait between Tasmania and the southern Australian mainland. This ecoregion, designated in the Marine Ecoregions of the World system by the World Wildlife Fund (WWF), includes both the Bass Strait Shelf and Tasmanian Shelf provincial level bioregions from the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) system.
