Bioregion
A bioregion is an ecologically and geographically defined area that is smaller than a biogeographic realm, but larger than an ecoregion or an ecosystem, in the World Wide Fund for Nature classification scheme. There is also an attempt to use the term in a rank-less generalist sense, similar to the terms "biogeographic area" or "biogeographic unit". It may be conceptually similar to an ecoprovince. It is also differently used in the environmentalist context, being coined by Berg and Dasmann (1977). WWF bioregions The World Wide Fund for Nature (WWF) scheme divides some of the biogeographic realms into bioregions, defined as "geographic clusters of ecoregions that may span several habitat types, but have strong biogeographic affinities, particularly at taxonomic levels higher than the species level (genus, family)." The WWF bioregions are as follows: * Afrotropical realm **Western Africa and Sahel **Central Africa **Eastern and Southern Africa ** Horn of Africa **Madagascar–I ...

Eudicots Of Western Australia
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants mainly characterized by having two seed leaves upon germination. The term derives from Dicotyledons. Traditionally they were called tricolpates or non-magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Some common and familiar eudicots include sunflower, dandelion, forget-me-not, cabbage, apple, buttercup, maple, and macadamia. Most leafy trees of midlatitudes also belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, and ''Ginkgo biloba'', which is not an angiosperm.

Tetratheca
''Tetratheca'' is a genus of around 50 to 60 species of shrubs endemic to Australia. It is classified in the botanical family Elaeocarpaceae, now known to encompass the family Tremandraceae, which the genus originally belonged to. It occurs throughout extratropical Australia, and has been recorded in every mainland state except the Northern Territory. Origin and evolution The origin of the genus is thought to be south-western Western Australia, radiating eastward. The distribution of ''Tetratheca'' is mainly across the temperate southern part of the continent. Most species are localised endemics and are highly disjunct from each other. Very few are widespread across Australia; none occurs in the Nullarbor Plain and only seven are found on both the western and the south-eastern sides. (McPherson, 2008). The formation of the Nullarbor is thought to have created a barrier to dispersal between the east and west. It is estimated that the family Elaeocarpaceae is 120 million years ...

Environment Protection And Biodiversity Conservation Act 1999
The ''Environment Protection and Biodiversity Conservation Act 1999'' (Cth) is an Act of the Parliament of Australia that provides a framework for protection of the Australian environment, including its biodiversity and its natural and culturally significant places. Enacted on 17 July 2000, it established a range of processes to help protect and promote the recovery of threatened species and ecological communities, and preserve significant places from decline. The Act is administered by the Department of Agriculture, Water and the Environment. Lists of threatened species are drawn up under the Act, and these lists, the primary reference to threatened species in Australia, are available online through the Species Profile and Threats Database (SPRAT). As an Act of the Australian Parliament, it relies for its constitutional validity upon the legislative powers of the Parliament granted by the Australian Constitution, and key provisions of the Act are largely based on a number ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banded Iron Formation
Banded iron formations (also known as banded ironstone formations or BIFs) are distinctive units of sedimentary rock consisting of alternating layers of iron oxides and iron-poor chert. They can be up to several hundred meters in thickness and extend laterally for several hundred kilometers. Almost all of these formations are of Precambrian age and are thought to record the Great Oxygenation Event, oxygenation of the Earth's oceans. Some of the Earth's oldest rock formations, which formed about (Year#SI prefix multipliers, Ma), are associated with banded iron formations. Banded iron formations are thought to have formed in sea water as the result of oxygen production by photosynthesis, photosynthetic cyanobacteria. The oxygen combined with dissolved iron in Earth's oceans to form insoluble iron oxides, which precipitated out, forming a thin layer on the ocean floor. Each band is similar to a varve, resulting from cyclic variations in oxygen production. Banded iron formation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loam
Loam (in geology and soil science) is soil composed mostly of sand (particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the , textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and |
Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interim Biogeographic Regionalisation Of Australia
The Interim Biogeographic Regionalisation for Australia (IBRA) is a biogeographic regionalisation of Australia developed by the Australian government's Department of Sustainability, Environment, Water, Population, and Communities. It was developed for use as a planning tool, for example for the establishment of a national reserve system. The first version of IBRA was developed in 1993–94 and published in 1995. Within the broadest scale, Australia is a major part of the Australasia biogeographic realm, as developed by the World Wide Fund for Nature. Based on this system, the world is also split into 14 terrestrial habitats, of which eight are shared by Australia. The Australian land mass is divided into 89 bioregions and 419 subregions. Each region is a land area made up of a group of interacting ecosystems that are repeated in similar form across the landscape. IBRA is updated periodically based on new data, mapping improvements, and review of the existing scheme. The most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elaeocarpaceae
Elaeaocarpaceae is a family of flowering plants. The family contains approximately 615 species of trees and shrubs in 12 genera."Elaeocarpaceae" In: Klaus Kubitzki (ed.). ''The Families and Genera of Vascular Plants'' vol. VI. Springer-Verlag: Berlin;Heidelberg, Germany. (2004). The largest genera are ''Elaeocarpus'', with about 350 species, and ''Sloanea'', with about 120. The species of Elaeocarpaceae are mostly tropical and subtropical, with a few temperate-zone species. Most species are evergreen. They are found in Madagascar, Southeast Asia, Australia, New Zealand, West Indies, and South America. Plants in this family have simple leaves, usually arranged alternately, sometimes in opposite pairs or whorled often clustered at the ends of the branches, usually with a toothed edge but sometimes reduced to scales. The flowers are arranged in leaf axils, singly or in groups and are radially symmetrical. The flowers usually have both male and female organs, four or five sepals an ...

Coolgardie (biogeographic Region)
Coolgardie is an Australian bioregion consisting of an area of low hills and plains of infertile sandy soil in Western Australia. It has an area of . It includes much of the Great Western Woodlands. Location and description This is a transition zone between the Mediterranean climate of Australia's south-west coast and the country's dry interior. The poor soil makes it unsuitable for agriculture but Coolgardie has been a gold and nickel mining area. It is bounded on the north by the arid Murchison bioregion, characterised by open Mulga woodlands and steppe. The low shrublands of the arid Nullarbor Plain lie to the east. The Mallee bioregion adjoins Coolgardie on the south. The Avon Wheatbelt bioregion is to the west. The Coolgardie bioregion, together with the coastal Hampton bioregion to the southeast, constitute the Coolgardie woodlands ecoregion defined by the World Wildlife Fund.
