Sphagnum Leucobryoides
''Ambuchanania leucobryoides'' is the only species in the monotypic genus ''Ambuchanania''. It is a ''Sphagnum''-like moss endemic to Tasmania. Originally described as a species of ''Sphagnum'', it is now a separate genus named after the original collector Alex M. Buchanan, (b.1944) an Australian botanist from the Tasmanian Herbarium in Hobart, (it was first collected in 1987). ''A. leucobryoides'' differs from the family Sphagnaceae in having elongate antheridia. It is entirely restricted to south-west Tasmania's Wilderness World Heritage Area where it occurs on white Precambrian quartzitic sand deposited by alluvial flows, and on margins of buttongrass (''Gymnoschoenus sphaerocephalus'') sedge land. Species most commonly found in association with ''A. leucobryoides'' include: ''Leptocarpus tenax'', ''Chordifex hookeri'', and ''Actinotus suffocatus''. Currently, ''A. leucobryoides'' is listed as rare under the Tasmanian Threatened Species Protection Act 1995. Description Ma ...

Alluvial Deposit
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the Fre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spore
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Two gametes fuse to form a zygote which develops into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Threatened Species Protection Act 1995
The ''Threatened Species Protection Act 1995'' (TSP Act), is an act of the Parliament of Tasmania that provides the statute relating to conservation of flora and fauna. Its long title is An Act to provide for the protection and management of threatened native flora and fauna and to enable and promote the conservation of native flora and fauna. It received the royal assent on 14 November 1995. As of 25 November 2020, the TSP Act is administered by the Department of Primary Industries, Parks, Water and Environment (Tasmania) and is the primary legislation for the listing, protection and conservation of threatened native flora and fauna in Tasmania. Threatened species in Tasmania can also be listed on the Environment Protection and Biodiversity Conservation Act 1999, which is the primary national legislation for the protection of threatened species in Australia. The objectives of the TSP Act are to ensure the survival of native flora and fauna as well to encourage, educate and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinotus Suffocatus
''Actinotus suffocatus'', the crimson flannelflower, is a small, perennial herb endemic to the Australian State of Tasmania. It is primarily found in high-elevation habitats in wet situations, except in the far south-west of the island, where it occurs down to sea level in continually moist habitats. Taxonomy ''Actinotus suffocatus'' was described originally as ''Hemiphues suffocata'' by Joseph Dalton Hooker from plants gathered by R.C.Gunn at Fatigue Hill (nowadays Calders Lookout), near Mount Arrowsmith, in central western Tasmania, and later transferred by Leonard Rodway to the genus ''Actinotus ''Actinotus'' is a genus of flowering plants in the family Apiaceae, subfamily Mackinlayoideae, with about 18 species.

Gymnoschoenus Sphaerocephalus
''Gymnoschoenus sphaerocephalus'', commonly known as buttongrass, is a species of tussock-forming sedge from southeastern Australia. It forms part of a unique habitat in Tasmania. It was originally described as ''Chaetospora sphaerocephala'' by Scottish botanist Robert Brown in his 1810 work ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'', before being given its current binomial name in 1858 by Joseph Dalton Hooker. ''G. sphaerocephalus'' is a perennial sedge species which forms a clump or tussock. The leaf blades reach in length, and in width. The round flowerheads arise out of the tussock, on culms which are up to high. They are around in diameter and made up of flattened spikelets long. Its root system is a mass of fleshy carbohydrate-rich rhizomes, which are edible. In New South Wales it is found from Gibraltar Range (and Myall Lakes on the coast) south to Robertson. In Victoria the plant is known from at least two locations, one to the east of Melbourne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards.

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

Tasmanian Wilderness World Heritage Area
The Tasmanian Wilderness World Heritage Area, abbreviated to TWWHA, is a World Heritage Site in Tasmania, Australia. It is one of the largest conservation areas in Australia, covering , or almost 25% of Tasmania. It is also one of the last expanses of temperate wilderness in the world, and includes the South West Wilderness. The main industry of the TWWHA is tourism, yet the region has a lack of development partially due to the juxtaposition of development with the idea of pristine nature. There is no permanent habitation in the area save for small parts on the periphery. The region is known for activities such as bushwalking, whitewater rafting, and climbing. The Tasmanian Wilderness qualifies for 7 out of the 10 classification criteria evaluated for World Heritage. Along with Mount Tai in China, it is the highest measurement attained for World Heritage Site status on Earth. The TWWHA was first placed on the World Heritage List in 1982 under joint arrangements between the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
