At the higher taxonomic levels the Australian flora is similar to that of the rest of the world; most vascular plant families are represented within the native flora, with the exception of the cacti, birch and a few others, while 9 families occur only in Australia.
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.
Australia has a rich variety of endemic legume species that thrive in nutrient-poor soils because of their symbiosis with Rhizobia bacteria and mycorrhizal fungi. Well-known Australian fauna include monotremes (the platypus and echidna); a host of marsupials, including the kangaroo, koala, wombat; and birds such as the emu and kookaburra.
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 ...
The wildlife of Canada or biodiversity of Canada consist of over 80,000 classified species, [a] and an equal number thought yet to be recognized. [3] Known fauna and flora have been identified from five kingdoms: [4] protozoa represent approximately 1% of recorded species; chromist (approximately 4); fungis (approximately 16%); plants ...
The natural history of Australia has been shaped by the geological evolution of the Australian continent from Gondwana and the changes in global climate over geological time. The building of the Australian continent and its association with other land masses, as well as climate changes over geological time, have created the unique flora and ...
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 ...
The ecology of Sydney, located in the state of New South Wales, Australia, is diverse for its size, [1] where it would mainly feature biomes such as grassy woodlands or savannas and some sclerophyll forests, with some pockets of mallee shrublands, riparian forests, heathlands, and wetlands, in addition to small temperate and subtropical rainforest fragments.
