Myrtales Of Australia
The Myrtales are an order of flowering plants placed as a sister to the eurosids II clade as of the publishing of the ''Eucalyptus grandis'' genome in June 2014. The APG III system of classification for angiosperms still places it within the eurosids. This finding is corroborated by the placement of the Myrtales in the Malvid clade by the One Thousand Plant Transcriptomes Initiative. The following families are included as of APGIII: * Alzateaceae S. A. Graham * Combretaceae R. Br. ( leadwood family) * Crypteroniaceae A. DC. * Lythraceae J. St.-Hil. ( loosestrife and pomegranate family) * Melastomataceae Juss. (including Memecylaceae DC.) * Myrtaceae Juss. (myrtle family; including Heteropyxidaceae Engl. & Gilg, Psiloxylaceae Croizat) * Onagraceae Juss. (evening primrose and Fuchsia family) * Penaeaceae Sweet ex Guill.

Melaleuca
''Melaleuca'' () is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles or tea-trees (although the last name is also applied to species of '' Leptospermum''). They range in size from small shrubs that rarely grow to more than high, to trees up to . Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers. Melaleucas are an important food source for nectarivorous insects, birds, and mammals. Many are popular garden plants, either for their attractive flowers or as dense screens and a few have economic value for producing fencing and oils such as "tea tree" oil. Most melaleucas are endemic to Australia, with a few also occurring in Malesia. Seven are endemic to New Caledonia, and one is found only on (Australia's) Lord Howe Island. Melaleucas are found in a wide variety of habitats. Many are adapted for life in swamp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Rehabilitation
Land rehabilitation as a part of environmental remediation is the process of returning the land in a given area to some degree of its former state, after some process (industry, natural disasters, etc.) has resulted in its damage. Many projects and developments will result in the land becoming degraded, for example mining, farming and forestry. Mine rehabilitation Modern mine rehabilitation aims to minimize and mitigate the environmental effects of modern mining, which may in the case of open pit mining involve movement of significant volumes of rock. Rehabilitation management is an ongoing process, often resulting in open pit mines being backfilled. After mining finishes, the mine area must undergo rehabilitation. * Waste dumps are contoured to flatten them out, to further stabilize them against erosion. * If the ore contains sulfides it is usually covered with a layer of clay to prevent access of rain and oxygen from the air, which can oxidize the sulfides to produce sulfur ...

Monoterpene
Monoterpenes are a class of terpenes that consist of two isoprene units and have the molecular formula C10H16. Monoterpenes may be linear (acyclic) or contain rings (monocyclic and bicyclic). Modified terpenes, such as those containing oxygen functionality or missing a methyl group, are called monoterpenoids. Monoterpenes and monoterpenoids are diverse. They have relevance to the pharmaceutical, cosmetic, agricultural, and food industries. Biosynthesis Monoterpenes are derived biosynthetically from units of isopentenyl pyrophosphate, which is formed from acetyl-CoA via the intermediacy of mevalonic acid in the HMG-CoA reductase pathway. An alternative, unrelated biosynthesis pathway of IPP is known in some bacterial groups and the plastids of plants, the so-called MEP-(2-methyl-D-erythritol-4-phosphate) pathway, which is initiated from C5 sugars. In both pathways, IPP is isomerized to DMAPP by the enzyme isopentenyl pyrophosphate isomerase. Geranyl pyrophosphate is the precurso ...

Calcareous
Calcareous () is an adjective meaning "mostly or partly composed of calcium carbonate", in other words, containing lime or being chalky. The term is used in a wide variety of scientific disciplines. In zoology ''Calcareous'' is used as an adjectival term applied to anatomical structures which are made primarily of calcium carbonate, in animals such as gastropods, i.e., snails, specifically about such structures as the operculum, the clausilium, and the love dart. The term also applies to the calcium carbonate tests of often more or less microscopic Foraminifera. Not all tests are calcareous; diatoms and radiolaria have siliceous tests. The molluscs are calcareous, as are calcareous sponges ( Porifera), that have spicules which are made of calcium carbonate. In botany ''Calcareous grassland'' is a form of grassland characteristic of soils containing much calcium carbonate from underlying chalk or limestone rock. In medicine The term is used in pathology, for example i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leonora, Western Australia
Leonora is a town in the Goldfields-Esperance region of Western Australia, located northeast of the state capital, Perth, and north of the city of Kalgoorlie. History The first European explorer to visit the area was John Forrest in 1869. On 21 June 1869 Forrest's party made camp near a conspicuous hill, which Forrest named Mount Leonora, after his six-year-old niece Frances (Fanny) Leonora Hardey. In 1895, gold was discovered in the area by prospector Edward "Doodah" Sullivan at the Johannesburg lease just north of the current townsite. In the following two years a number of rich finds resulted in rapid development of the area. The Sons of Gwalia gold mine brought Leonora to the attention of the world. By 1897 a residential and business area had been established, and the town was gazetted as Leonora. Leonora had a single track passenger tramway linking the town and nearby Gwalia, from 1901 to 1921. Initially steam driven, the service was electric from November 1908, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arid
A region is arid when it severely lacks available water, to the extent of hindering or preventing the growth and development of plant and animal life. Regions with arid climates tend to lack vegetation and are called xeric or desertic. Most arid climates straddle the Equator; these regions include parts of Africa, Asia, South America, North America, and Australia. Change over time The distribution of aridity at any time is largely the result of the general circulation of the atmosphere. The latter does change significantly over time through climate change. For example, temperature increase by 1.5–2.1 percent across the Nile Basin over the next 30–40 years could change the region from semi-arid to arid, significantly reducing the land usable for agriculture. In addition, changes in land use can increase demands on soil water and thereby increase aridity.
