Currently, about 10,000 to 12,000 species of algae are known for Australia. [31] The algal flora of Australia is unevenly documented: northern Australia remains largely uncollected for seaweeds and marine phytoplankton, descriptions of freshwater algae are patchy, and the collection of terrestrial algae has been almost completely neglected. [32]
The Australian freshwater ecoregions were adapted from the freshwater fish biogeographic provinces identified by Peter Unmack and G.R. Allen, S.H. Midgley, and M. Allen, who were also part of the WWF team. The freshwater fish provinces "were derived through similarity analyses, parsimony analysis, and drainage-based plots of species ranges". [3]
Canada's 15 terrestrial ecozones are further subdivided into 53 ecoprovinces, 194 ecoregions, and 1,027 ecodistricts. [13]Canada is characterized by a wide range of both meteorologic and geological regions that are divided into fifteen terrestrial and five marine ecozones, [14] such as the forests of British Columbia and Central Canada, the prairies of Western Canada, the tundra of Northern ...
The red kangaroo is the largest extant macropod and is one of Australia's heraldic animals, appearing with the emu on the coat of arms of Australia. [1]The fauna of Australia consists of a large variety of animals; some 46% of birds, 69% of mammals, 94% of amphibians, and 93% of reptiles that inhabit the continent are endemic to it.
These Eastern Australian temperate forests have the greatest relief, the most rainfall, the most abundant and varied flora and fauna, and the densest human settlement. Between the Eastern Highlands and the Western Plateau lies the Central Lowlands, which are made up of the Great Artesian Basin and Australia's largest river systems, the Murray ...
Canada covers 9,984,670 km 2 (3,855,100 sq mi) and a panoply of various geoclimatic regions, of which there are seven main regions. [9] Canada also encompasses vast maritime terrain, with the world's longest coastline of 243,042 kilometres (151,019 mi). [20] The physical geography of Canada is widely varied.
The fauna of Canada consist of approximately 200 mammal species, over 460 native bird species, 43 amphibian species, 43 reptile species, and 1,200 fish species. [ 1 ] [ 2 ] The biology survey of Canada cites that there are approximately 55,000 species of insects and 11,000 species of mites and spiders.

[8] The Western Australian system of regions defined by the Government of Western Australia for purposes of economic development administration, which excludes the Perth metropolitan area, is a series of nine regions. The nine defined regions are: Gascoyne; Goldfields–Esperance
