Marsilea Drummondii
''Marsilea drummondii'' is a species of fern known by the common name nardoo. It is native to Australia, where it is widespread and common, particularly in inland regions. It is a rhizomatous perennial aquatic fern that roots in mud substrates and produces herbage that floats on the surface of quiet water bodies. It occurs in water up to one metre deep.''Marsilea drummondii''. . It occurs in abundance after s.Thomas, A [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Carl Heinrich Braun
Alexander Carl Heinrich Braun (10 May 1805 – 29 March 1877) was a German botanist from Regensburg, Bavaria. His research centered on the morphology of plants. Biography He studied botany in Heidelberg, Paris and Munich. In 1833 he began teaching botany at the Polytechnic School of Karlsruhe, staying there until 1846. Afterwards he was a professor of botany in Freiburg (from 1846), Giessen (from 1850) and at the University of Berlin (1851), where he remained until 1877. While in Berlin, he was also director of the botanical garden. In 1852, he was elected a foreign member of the Royal Swedish Academy of Sciences. Braun is largely known for his research involving plant morphology. He accepted evolution but was a critic of Darwinism. He was a proponent of vitalism, a popular 19th-century speculative theory that claimed that a regulative force existed within living matter in order to maintain functionality. Braun made important contributions in the field of cell theory. From h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beriberi
Thiamine deficiency is a medical condition of low levels of thiamine (Vitamin B1). A severe and chronic form is known as beriberi. The two main types in adults are wet beriberi and dry beriberi. Wet beriberi affects the cardiovascular system, resulting in a fast heart rate, shortness of breath, and leg swelling. Dry beriberi affects the nervous system, resulting in numbness of the hands and feet, confusion, trouble moving the legs, and pain. A form with loss of appetite and constipation may also occur. Another type, acute beriberi, found mostly in babies, presents with loss of appetite, vomiting, lactic acidosis, changes in heart rate, and enlargement of the heart. Risk factors include a diet of mostly white rice, alcoholism, dialysis, chronic diarrhea, and taking high doses of diuretics. In rare cases, it may be due to a genetic condition that results in difficulties absorbing thiamine found in food. Wernicke encephalopathy and Korsakoff syndrome are forms of dry beriber ...

Flora Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 30,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (''Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae (''Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the large-scal ...

Marsilea
''Marsilea'' is a genus of approximately 65 species of aquatic ferns of the family Marsileaceae. The name honours Italian naturalist Luigi Ferdinando Marsili (1656–1730). These small plants are of unusual appearance and do not resemble common ferns. Common names include water clover and four-leaf clover because of the long-stalked leaves have four clover-like lobes and are either present above water or submerged. The sporocarps of some Australian species are very drought-resistant, surviving up to 100 years in dry conditions. On wetting, the gelatinous interior of the sporocarp swells, splitting it and releasing a worm-like mass that carries sori, eventually leading to germination of spores and fertilization. Uses As food Sporocarps of some Australian species such as ''Marsilea drummondii'' are edible and have been eaten by Aborigines and early white settlers, who knew it under the name ngardu or nardoo. Parts of ''Marsilea drummondii'' contain an enzyme which destroys t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curlewis, New South Wales
Curlewis is a parish and a rural village on the Kamilaroi Highway, 16 kilometres south of Gunnedah, New South Wales in Australia. The village boundaries are in the Gunnedah Shire local government area of the North West Slopes portion of the New England region. History Curlewis was founded by Henry Thomas Pike, a sawmiller from Norfolk who became the mayor of Gunnedah. In 1909, the railway station opened as a stop on the Mungindi branch line, but has since closed. The station building was demolished in May 2013 after the roof was damaged by a storm earlier that year. Livestock sales commenced in 1919 in Curlewis and were, for many years, held in alternate weeks at Gunnedah and Curlewis until improvements to the Gunnedah saleyards, eclipsed Curlewis's yardings and led to the yard’s closure. The lack of a nearby river has contributed to Curlewis having persistent water problems and water shortage. In 1950, the council had to de-silt an old earthen dam and erect a tank fr ...

Brigalow Belt South
The Brigalow Belt is a wide band of acacia-wooded grassland that runs between tropical rainforest of the coast and the semi-arid interior of Queensland, Australia. The Interim Biogeographic Regionalisation for Australia (IBRA) divides the Brigalow Belt into two IBRA regions, or bioregions, ''Brigalow Belt North'' (BBN) and ''Brigalow Belt South'' (BBS). The North and South Brigalow Belt are two of the 85 bioregions across Australia and the 15 bioregions in Queensland. Together they form most of the Brigalow tropical savanna ecoregion. Location and description The Northern Brigalow Belt covers just over 13.5 million hectares and reaches down from just north of Townsville, to Emerald and Rockhampton on the tropic, while the Southern Brigalow Belt runs from there down to the Queensland/New South Wales border and a little beyond until the habitat becomes the eucalyptus dominated Eastern Australian temperate forests. This large, complex strip of countryside covers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Burke And Wills Expedition
The Burke and Wills expedition was organised by the Royal Society of Victoria in Australia in 1860–61. It consisted of 19 men led by Robert O'Hara Burke and William John Wills, with the objective of crossing Australia from Melbourne in the south, to the Gulf of Carpentaria in the north, a distance of around 3,250 kilometres (approximately 2,000 miles). At that time most of the inland of Australia had not been explored by non-Indigenous people and was largely unknown to the European settlers. The expedition left Melbourne in winter. Very bad weather, poor roads and broken-down horse wagons meant they made slow progress at first. After dividing the party at Menindee on the Darling River Burke made good progress, reaching Cooper Creek at the beginning of summer. The expedition established a depot camp at the Cooper, and Burke, Wills and two other men pushed on to the north coast (although swampland stopped them from reaching the northern coastline). The return journey was plag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sheep
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus '' Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' (), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In Comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thiamine
Thiamine, also known as thiamin and vitamin B1, is a vitamin, an essential micronutrient, that cannot be made in the body. It is found in food and commercially synthesized to be a dietary supplement or medication. Phosphorylated forms of thiamine are required for some metabolic reactions, including the breakdown of glucose and amino acids. Food sources of thiamine include whole grains, legumes, and some meats and fish. Grain processing removes much of the vitamin content, so in many countries cereals and flours are enriched with thiamine. Supplements and medications are available to treat and prevent thiamine deficiency and disorders that result from it include beriberi and Wernicke encephalopathy. They are also used to treat maple syrup urine disease and Leigh syndrome. Supplements and medications are typically taken by mouth, but may also be given by intravenous or intramuscular injection. Thiamine supplements are generally well tolerated. Allergic reactions, inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
