Acacia Shirleyi
''Acacia shirleyi'', known colloquially as lancewood, is a species of ''Acacia'' native to Queensland and the Northern Territory in Australia. It grows as a tree to high, with dark grey or black stringy bark and blue-grey foliage. The yellow flowers appear from March to July. It grows in dry scrub, open forest or mixed Tropical and subtropical grasslands, savannas, and shrublands, savannah woodland. Indigenous people used the wood as fuel and to make hunting spears. Cattle can eat the foliage as fodder. Description The small tree has a single stem which is layered with dead bark and an umbrella shaped Habit (biology), habit. It typically grows to a height of around . The stringy bark is dark grey to black in colour, and the trunk can be up to thick. When cut or exposed, the bark will emit an odour reminiscent of viola odorata, violets. The evergreen linear to slightly curved phyllodes are around in length and wide. Veins are only found in the midrib area and are raised on b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Maiden
Joseph Henry Maiden (25 April 1859 – 16 November 1925) was a botanist who made a major contribution to knowledge of the Australian flora, especially the genus ''Eucalyptus''. This botanist is denoted by the author abbreviation when citing a botanical name. Life Joseph Maiden was born in St John's Wood in northwest London. He studied science at the University of London, but due to ill health he did not complete the course. As part of his treatment he was advised to take a long sea voyage, and so in 1880 he sailed for New South Wales. In 1881, Maiden was appointed first curator of the Technological Museum in Sydney (now the Powerhouse Museum), remaining there until 1896. While there, he published an article in 1886 describing what he called "some sixteenth century maps of Australia". These were the so-called Dieppe maps, the Rotz (1547), the Harleian or Dauphin (mid-1540s), and the Desceliers (1550), photo-lithographic reproductions of which had been published by the Brit ...

Acacia Distans
''Acacia distans'' is a tree belonging to the genus '' Acacia'' and the subgenus ''Juliflorae'' that is endemic to arid parts of western Australia. Description The tree typically grows to a height of and has fissured and fibrous grey bark. It has slender glabrous slender and sometimes pendulous branchlets with sericeous new shoots with hairs that become silver with age. Like most species of ''Acacia'' it has phyllodes rather than true leaves. The thinly coriaceous grey-green phyllodes have a linear to curved shape and are in length and a width of wide and are finely striated with a central nerve that is more prominent than the others. It blooms between March and May and produces yellow flowers. The rudimentary inflorescences form two-headed racemes along an axes with cylindrical flower-spikes that have a length of up to and a diameter of packed with golden flowers. The thinly crustose seed pods that form after flowering have a linear shape but are raised over and shallowly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symbiotic
Symbiosis (from Greek , , "living together", from , , "together", and , bíōsis, "living") is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, must be of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms". The term was subject to a century-long debate about whether it should specifically denote mutualism, as in lichens. Biologists have now abandoned that restriction. Symbiosis can be obligatory, which means that one or more of the symbionts depend on each other for survival, or facultative (optional), when they can generally live independently. Symbiosis is also classified by physical attachment. When symbionts form a single body it is called conjunctive symbiosis, while all other arrangements are called disjunctive symbiosis."symbiosis."

CSIRO
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an Australian Government agency responsible for scientific research. CSIRO works with leading organisations around the world. From its headquarters in Canberra, CSIRO maintains more than 50 sites across Australia and in France, Chile and the United States, employing about 5,500 people. Federally funded scientific research began in Australia years ago. The Advisory Council of Science and Industry was established in 1916 but was hampered by insufficient available finance. In 1926 the research effort was reinvigorated by establishment of the Council for Scientific and Industrial Research (CSIR), which strengthened national science leadership and increased research funding. CSIR grew rapidly and achieved significant early successes. In 1949, further legislated changes included renaming the organisation as CSIRO. Notable developments by CSIRO have included the invention of atomic absorption spectroscopy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astringent
An astringent (sometimes called adstringent) is a chemical that shrinks or constricts body tissues. The word derives from the Latin ''adstringere'', which means "to bind fast". Calamine lotion, witch hazel, and yerba mansa, a Californian plant, are astringents. Astringency, the dry, puckering or numbing mouthfeel caused by the tannins in unripe fruits, lets the fruit mature by deterring eating. Ripe fruits and fruit parts including blackthorn (sloe berries), ''Aronia'' chokeberry, chokecherry, bird cherry, rhubarb, quince and persimmon fruits (especially those which are unripe), banana skins (or unripe bananas), cashew fruits and acorns are astringent. Citrus fruits, like lemons, are somewhat astringent. Tannins, being a kind of polyphenol, bind salivary proteins and make them precipitate and aggregate, producing a rough, "sandpapery", or dry sensation in the mouth. The tannins in some teas, coffee, and red grape wines like Cabernet Sauvignon and Merlot produce mild ast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tannin
Tannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids. The term ''tannin'' (from Anglo-Norman ''tanner'', from Medieval Latin ''tannāre'', from ''tannum'', oak bark) refers to the use of oak and other bark in tanning animal hides into leather. By extension, the term ''tannin'' is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with various macromolecules. The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation (acting as pesticides) and might help in regulating plant growth. The astringency from the tannins is what causes the dry and puckery feeling in the mouth following the consumption of unripened fruit, red wine or tea. Likewise, the destruction or modification of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Savannah
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in f ...

Victoria River (Northern Territory)
The Victoria River is a river in the Victoria Bonaparte bioregion of the Northern Territory, Australia. Location and features Flowing for from its source, south of the Judbarra / Gregory National Park, until it enters Joseph Bonaparte Gulf in the Timor Sea, the Victoria River is the longest singularly named permanent river in the Northern Territory. Part of the area adjoining the river mouth has been identified as the Legune (Joseph Bonaparte Bay) Important Bird Area because of its importance for waterbirds. However, the longest permanent river in the Northern Territory, as defined by international standards, is the Katherine/Daly River. This is a single river with two separating (at the Flora River tributary) European names. This great river was, until recently, deemed as two separate rivers due to the European naming conventions of the time. Its journey begins just south of Jabiru, high in the Arnhem Land escarpment as a trickle until it flows into the Timor Sea some ...
