Ambuchanania
''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. Descripti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sphagnales
The Sphagnales is an order of mosses with four living genera: ''Ambuchanania'', ''Eosphagnum'', ''Flatbergium'', and ''Sphagnum''. The genus ''Sphagnum'' contains the largest number of species currently discovered (about 200, number varying according to the various authors). The other genera are currently limited to one species each. References Sphagnales, Moss orders {{moss-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sphagnum
''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, also bog moss and quacker moss (although that term is also sometimes used for peat). Accumulations of ''Sphagnum'' can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 to 26 times as much water as their dry weight, depending on the species.Bold, H. C. 1967. Morphology of Plants. second ed. Harper and Row, New York. p. 225–229. The empty cells help retain water in drier conditions. As ''Sphagnum'' moss grows, it can slowly spread into drier conditions, forming larger mires, both raised bogs and blanket bogs. Thus, ''Sphagnum'' can influence the composition of such habitats, with some describing ''Sphagnum'' as 'habitat manipulators' or 'autogenic ecosystem engineers'. These peat accumulations then provide habitat for a wide array of peatland plants, including sedges and Calcifuge, ericaceous shrubs, as ...

Moss
Mosses are small, non-vascular plant, non-vascular flowerless plants in the taxonomic phylum, division Bryophyta (, ) ''sensu stricto''. Bryophyta (''sensu lato'', Wilhelm Philippe Schimper, Schimp. 1879) may also refer to the parent group bryophytes, which comprise Marchantiophyta, liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaf, leaves that are generally only one cell thick, attached to a plant stem, stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing sporangium, spores. They are typically tall, though some species ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Spore
In biology, a spore is a unit of sexual reproduction, sexual (in fungi) or asexual reproduction that may be adapted for biological dispersal, dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the Biological life cycle, life cycles of many plants, algae, fungus, fungi and protozoa. They were thought to have appeared as early as the mid-late Ordovician period as an adaptation of early land plants. 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. In some rare cases, a diploid spore is also p ...

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 ... [...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.

Alluvial Deposit
Alluvium (, ) 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 French term for alluvium) as new land formed by deposition of s ...
