Stephen J
Stephen or Steven is a common English first name. It is particularly significant to Christians, as it belonged to Saint Stephen ( grc-gre, Στέφανος ), an early disciple and deacon who, according to the Book of Acts, was stoned to death; he is widely regarded as the first martyr (or "protomartyr") of the Christian Church. In English, Stephen is most commonly pronounced as ' (). The name, in both the forms Stephen and Steven, is often shortened to Steve or Stevie. The spelling as Stephen can also be pronounced which is from the Greek original version, Stephanos. In English, the female version of the name is Stephanie. Many surnames are derived from the first name, including Stephens, Stevens, Stephenson, and Stevenson, all of which mean "Stephen's (son)". In modern times the name has sometimes been given with intentionally non-standard spelling, such as Stevan or Stevon. A common variant of the name used in English is Stephan ; related names that have found some c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paraburdoo, Western Australia
Paraburdoo is a mining town in the Pilbara region of Western Australia. The region is served by Paraburdoo Airport, which is situated from the town. Etymology The name of the town comes from an Aboriginal word said to mean "feathered meat", which could refer to abundant Little corella or flock pigeons. It could also mean Rock Cave (para means rock and buradoo means hole or cave) to refer to caves nearby. Economy Paraburdoo was developed in the early 1970s to support Hamersley Iron's (now Pilbara Iron) local iron ore mining operations, and was gazetted as a town in 1972. The town provides housing to workers of the three nearby Rio Tinto mines, those being the Channar, Eastern Range and Paraburdoo mine.Mining Rio Tinto Iron Ore website, accessed: 6 November 2010 Geography Paraburdoo is located north ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Australia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proteales Of Australia
Proteales is an order of flowering plants consisting of three (or four) families. The Proteales have been recognized by almost all taxonomists. The representatives of the Proteales are very different from each other. The order contains plants that do not look alike at all. What they have in common is seeds with little or no endosperm. The ovules are often atropic. Families In the classification system of Dahlgren the Proteales were in the superorder Proteiflorae (also called Proteanae). The APG II system of 2003 also recognizes this order, and places it in the clade eudicots with this circumscription: * order Proteales :* family Nelumbonaceae :* family Proteaceae family Platanaceae">Platanaceae.html" ;"title=" family Platanaceae"> family Platanaceae with "+ ..." = optionally separate family (that may be split off from the preceding family). The APG III system of 2009 followed this same approach, but favored the narrower circumscription of the three families, firmly reco ...

Grevillea
''Grevillea'', commonly known as spider flowers, is a genus of about 360 species of evergreen flowering plants in the family Proteaceae. Plants in the genus ''Grevillea'' are shrubs, rarely trees, with the leaves arranged alternately along the branches, the flowers zygomorphic, arranged in racemes at the ends of branchlets, and the fruit a follicle that splits down one side only, releasing one or two seeds. Description Plants in the genus ''Grevillea'' are shrubs, rarely small trees with simple or compound leaves arranged alternately along the branchlets. The flowers are zygomorphic and typically arranged in pairs along a sometimes branched raceme at the ends of branchlets. The flowers are bisexual, usually with four tepals in a single whorl. There are four stamens and the gynoecium has a single carpel. The fruit is a thin-walled follicle that splits down only one side, releasing one or two seeds before the next growing season. Taxonomy The genus ''Grevillea'' was first forma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Department Of Biodiversity, Conservation And Attractions (Western Australia)
The Department of Biodiversity, Conservation and Attractions (DBCA) is the Government of Western Australia, Western Australian government department responsible for managing lands and waters described in the ''Conservation and Land Management Act 1984'', the ''Rottnest Island Authority Act 1987'', the ''Swan and Canning Rivers Management Act 2006'', the ''Botanic Gardens and Parks Authority Act 1998'', and the ''Zoological Parks Authority Act 2001'', and implementing the state's conservation and environment legislation and regulations.

DBCA was formed on 1 July 2017 by the merger of the Department of Parks and Wildlife (Western Australia), Department of Parks and Wildlife (DPaW), the Botanic Gardens and Parks Authority, the Zoological Parks Authority and the Rottnest Island Authority. The former DPaW became the Parks and Wildlife Service. Status Parks and Wildlife Service The Formerly the Depar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Declared Rare And Priority Flora List
The Declared Rare and Priority Flora List is the system by which Western Australia's conservation flora are given a priority. Developed by the Government of Western Australia's Department of Environment and Conservation, it was used extensively within the department, including the Western Australian Herbarium. The herbarium's journal, ''Nuytsia'', which has published over a quarter of the state's conservation taxa, requires a conservation status to be included in all publications of new Western Australian taxa that appear to be rare or endangered. The system defines six levels of priority taxa: ;X: Threatened (Declared Rare Flora) – Presumed Extinct Taxa: These are taxa that are thought to be extinct, either because they have not been collected for over 50 years despite thorough searching, or because all known wild populations have been destroyed. They have been declared as such in accordance with the Wildlife Conservation Act 1950, and are therefore afforded legislative protecti ...

Mulga (habitat)
Mulga is a type of habitat composed of woodland or open forest dominated by the mulga tree, '' Acacia aneura'', or similar species of '' Acacia''. Regions It is found across Australia, covering 20% of arid regions, including much of southwestern Queensland, New South Wales, South Australia, and Western Australia. The Mulga Lands are an interim Australian bioregion located in northwestern New South Wales and southwestern Queensland in eastern Australia consisting of dry sandy plains with low mulga woodlands and shrublands that are dominated by mulga. The Western Australian mulga shrublands is a large dry World Wildlife Fund ecoregion of inland Western Australia. Vegetation The vegetation type is associated with the extensive plains of the continent's interior and other arid regions with infrequent and irregular rainfall. Mulga country intersperses with other vegetation such as spinifex, dominated by low mounds of '' Triodia'', and wattle scrub (Mimosaceae) or interrupted by gra ...

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] |
Scree
Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. Talus deposits typically have a concave upwards form, where the maximum inclination corresponds to the angle of repose of the mean debris particle size. The exact definition of scree in the primary literature is somewhat relaxed, and it often overlaps with both ''talus'' and ''colluvium''. The term ''scree'' comes from the Old Norse term for landslide, ''skriða'', while the term ''talus'' is a French word meaning a slope or embankment. In high-altitude arctic and subarctic regions, scree slopes and talus deposits are typically adjacent to hills and river valleys. These steep slopes usually originate from late-Pleistocene periglacial processes. Notable scree sites in Eastern North America include the Ice Caves at White Rocks National Recreation Area in southern Ve ...

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 |
Newman, Western Australia
Newman, originally named Mount Newman until 1981, is a town in the Pilbara region of Western Australia. It is located about north of Perth, and north of the Tropic of Capricorn. It can be reached by the Great Northern Highway. Newman is a modern mining town, with homes contrasting with the surrounding reddish desert. The 2021 population was 6,456. The Hickman Crater is north of Newman. History Newman was established as Mount Newman by Mt. Newman Mining Co. Pty Ltd (a subsidiary of BHP) in 1966 as a company town to support the development of iron ore deposits at nearby Mount Whaleback. The town takes its name from nearby Mount Newman, named in honour of government surveyor Aubrey Woodward Newman (son of Edward Newman who also died young) who died of typhoid aged 28 at Cue on 24 May 1896, while on an expedition from Nannine to the Ophthalmia Range. William Frederick Rudall then took charge of the expedition and named Mount Newman to honour his deceased leader. Aborig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
