Poa Gunnii
''Poa gunnii'' is a Aboriginal Tasmanians, Tasmanian endemic tussock grass considered one of the most abundant and common in alpine and subalpine environments from about 800 m to above 1400 m. However it can be found to near sea level in the south of the island state where a cooler climate is prevalent. The genus ''Poa'' belongs to the family Poaceae. Tasmania has 16 native and 6 introduced species of ''Poa''. Description ''Poa gunnii'' is a very variable species. The most common subalpine and alpine form is stunted but grows up to 20 cm high while forms of ''P. gunnii'' at lower altitudes towards sea level are usually taller to 70 cm high and with longer leaves. Leaf sheaths, green or purplish; leaves less than 1mm in diameter, hard, usually round in cross-section. Blades up to 30 cm long, inrolled or folded. Ligules up to 2mm long, firm with tiny hairs on their margins and backs. Flowering spikelets are broadly ovate to lanceolate, 2–6 flowered, green ...

Aboriginal Tasmanians
The Aboriginal Tasmanians (Palawa kani: ''Palawa'' or ''Pakana'') are the Aboriginal people of the Australian island of Tasmania, located south of the mainland. For much of the 20th century, the Tasmanian Aboriginal people were widely, and erroneously, thought of as being an extinct cultural and ethnic group that had been intentionally exterminated by white settlers. Contemporary figures (2016) for the number of people of Tasmanian Aboriginal descent vary according to the criteria used to determine this identity, ranging from 6,000 to over 23,000. First arriving in Tasmania (then a peninsula of Australia) around 40,000 years ago, the ancestors of the Aboriginal Tasmanians were cut off from the Australian mainland by rising sea levels c. 6000 BC. They were entirely isolated from the outside world for 8,000 years until European contact. Before British colonisation of Tasmania in 1803, there were an estimated 3,000–15,000 Palawa. The Palawa population suffered a drastic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Viviparity
Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the mother. The term 'viviparity' and its adjective form 'viviparous' derive from the Latin ''vivus'' meaning "living" and ''pario'' meaning "give birth to". Reproductive mode Five modes of reproduction have been differentiated in animals based on relations between zygote and parents. The five include two nonviviparous modes: ovuliparity, with external fertilisation, and oviparity, with internal fertilisation. In the latter, the female lays zygotes as eggs with a large vitellus, yolk; this occurs in all birds, most reptiles, and some fishes. These modes are distinguished from viviparity, which covers all the modes that result in live birth: *Histotrophic viviparity: the zygotes develop in the female's oviducts, but find their nutrients b ...

Ronald Campbell Gunn
Ronald Campbell Gunn, Fellow of the Royal Society, FRS, (4 April 1808 – 13 March 1881) was a South African-born Australian Botany, botanist and politician. Early life Gunn was born at Cape Town, Cape Colony, (now South Africa), the son of William Gunn, lieutenant in the 72nd Regiment of Foot, 72nd Regiment, and his wife Margaret, ''née'' Wilson. Gunn accompanied his father to Mauritius, the West Indies, and Scotland where he was educated. Gunn was given an appointment in the Royal Engineers at Barbados, but left there in 1829 to go to Van Diemen's Land (now Tasmania), where he obtained the position of superintendent of convict barracks at Hobart Town. Career In 1830 Gunn became superintendent of convicts for North Tasmania at Launceston, Tasmania, Launceston. In 1831 Gunn became acquainted with an early Tasmanian botanist, Robert William Lawrence (1807–1833), who encouraged his interest in botany and placed him in touch with Sir William Jackson Hooker and Dr Lindley, with ...

Mount Wellington (Tasmania)
Mount Wellington (officially kunanyi / Mount Wellington ()) is a mountain in the southeast of Tasmania, Australia. It is the summit of the Wellington Range and is within Wellington Park reserve. Hobart, Tasmania's capital city, is located at the foot of the mountain. The mountain rises to above sea level and is frequently covered by snow, sometimes even in summer, and the lower slopes are thickly forested, but crisscrossed by many walking tracks and a few fire trails. There is also a sealed narrow road to the summit, about from Hobart central business district. An enclosed lookout near the summit has views of the city below and to the east, the Derwent estuary, and also glimpses of the World Heritage Area nearly west. From Hobart, the most distinctive feature of Mount Wellington is the cliff of dolerite columns known as the Organ Pipes. Geology The low-lying areas and foothills of Mount Wellington were formed by slow geological upsurge when the whole Hobart area was a lo ...
