Triodia Scintillans
''Triodia scintillans'', the sparkling spinifex, or salt and vinegar chips spinifex is a species of grass in the genus ''Triodia (plant), Triodia''. It tastes like salt and vinegar potato chips. Names The specific epithet ''scintillans'' was chosen with help from Alex George (botanist), Alex George and derives from the Latin word which means "to sparkle". This refers to the distinct sparkly droplets on young leaves which is especially apparent in direct sun. The common name "sparkling spinifex" is a calque of that Latin binomial. Although this plant is not in the genus ''Spinifex (coastal grass), Spinifex'', members of the genus ''Triodia'' are commonly called "spinifex". ''Triodia vanleeuwenii, T. vanleeuwenii'' is also called sparking spinifex. ''Triodia scintillans'' is referred to as salt and vinegar chips spinifex because the little leaf droplets have a similar taste to the chips. The plant was not tasted intentionally, and eating it is not recommended. The species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fortescue River
The Fortescue River is an ephemeral river in the Pilbara region of Western Australia. It is the third longest river in the state. Course The river rises near Deadman Hill in the Ophthalmia Range about 30 km south of Newman, Western Australia, Newman. The river flows in a northerly direction parallel with the Great Northern Highway until it crosses the highway just south of the Marble Bar, Western Australia, Marble Bar turn-off. The river then runs north-west then west crossing the Great Northern Highway again, north of the Auski Roadhouse. Approximately north of Newman, the river flows through the Fortescue Marsh, an important wetland. The river continues to head west crossing Highway 1 at the Fortescue Roadhouse () and discharges into the Indian Ocean at Mardie Station about 40 km south-west of Dampier, Western Australia, Dampier. Tributaries The river is known to have 24 tributary, tributaries that include: Western Creek, Warrawanda Creek, Shovelanna Creek, Kal ...

Western Australia
Western Australia (WA) is the westernmost state of Australia. 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 land area of , and is also the List of country subdivisions by area, second-largest subdivision of any country on Earth. Western Australia has a diverse range of climates, including tropical conditions in the Kimberley (Western Australia), Kimberley, deserts in the interior (including the Great Sandy Desert, Little Sandy Desert, Gibson Desert, and Great Victoria Desert) and a Mediterranean climate on the south-west and southern coastal areas. the state has 2.965 million inhabitants—10.9 percent of the national total. Over 90 percent of the state's population live in the South-West Land Division, south-west corner and around 80 percent live in the state capital Perth, leaving the remainder ...

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Chloroplast DNA
Chloroplast DNA (cpDNA), also known as plastid DNA (ptDNA) is the DNA located in chloroplasts, which are photosynthetic organelles located within the cells of some eukaryotic organisms. Chloroplasts, like other types of plastid, contain a genome separate from that in the cell nucleus. The existence of chloroplast DNA was identified biochemically in 1959, and confirmed by electron microscopy in 1962. The discoveries that the chloroplast contains ribosomes and performs protein synthesis revealed that the chloroplast is genetically semi-autonomous. The first complete chloroplast genome sequences were published in 1986, ''Nicotiana tabacum'' (tobacco) by Sugiura and colleagues and '' Marchantia polymorpha'' (liverwort) by Ozeki et al. Since then, tens of thousands of chloroplast genomes from various species have been sequenced. Molecular structure Chloroplast DNAs are circular, and are typically 120,000–170,000 base pairs long. They can have a contour length of around 30–60 mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roy Hill Station
Roy Hill Station is a pastoral lease and cattle station, located about south of the Roy Hill mine. Roy Hill Station was an important cattle station in the north-west, being on the Meekatharra- Nullagine Road and stock route. The station area is about . The station was established in 1886 by Nat Cooke, who owned Mallina Station. Mallina had suffered from several years drought so Cooke was keen to secure new pastures. The first official lease was granted to D. MacKay in 1890 for an area of . In 1915, the property was carrying 10,000 head of cattle. It is situated south of Mulga Downs Station, once owned by Lang Hancock and presently owned by his daughter Gina Rinehart.

External Transcribed Spacer
External transcribed spacer (ETS) refers to a piece of non-functional RNA, closely related to the internal transcribed spacer, which is situated outside structural ribosomal RNAs (rRNA) on a common precursor transcript. ETS sequences characteristic to an organism can be used to trace its phylogeny A phylogenetic tree or phylogeny is a graphical representation which shows the evolutionary history between a set of species or Taxon, taxa during a specific time.Felsenstein J.

Internal Transcribed Spacer
Internal transcribed spacer (ITS) is the spacer DNA situated between the small-subunit ribosomal RNA (rRNA) and large-subunit rRNA genes in the chromosome or the corresponding transcribed region in the polycistronic rRNA precursor transcript. Across life domains In bacteria and archaea, there is a single ITS, located between the 16S and 23S rRNA genes. Conversely, there are two ITSs in eukaryotes: ITS1 is located between 18S and 5.8S rRNA genes, while ITS2 is between 5.8S and 28S (in opisthokonts, or 25S in plants) rRNA genes. ITS1 corresponds to the ITS in bacteria and archaea, while ITS2 originated as an insertion that interrupted the ancestral 23S rRNA gene. Organization In bacteria and archaea, the ITS occurs in one to several copies, as do the flanking 16S and 23S genes. When there are multiple copies, these do not occur adjacent to one another. Rather, they occur in discrete locations in the circular chromosome. It is not uncommon in bacteria to carry tRNA ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...
