Sphagnopsida
Sphagnopsida is a class of mosses that includes a single subclass Sphagnidae, with two orders. It is estimated it originated about 465 million years ago, along with Takakia. The order Sphagnales contains four living genera: ''Ambuchanania'', ''Eosphagnum'', and ''Flatbergium'', which counts four species in total, and ''Sphagnum ''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, peat moss, also bog moss and quacker moss (although that term is also sometimes used for peat).

Moss
Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophyta (, ) '' sensu stricto''. Bryophyta (''sensu lato'', Schimp. 1879) may also refer to the parent group bryophytes, which comprise 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 leaves that are generally only one cell thick, attached to a 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 spores. They are typically tall, though some species are much larger. ''Dawsonia'', the tallest moss in the world, can grow to in height. There are a ...

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 ''Gymnoschoenus sphaerocephalus'', commonly known as buttongrass, is a species of tussock-forming sedge from southeastern Australia.

Sphagnum
''Sphagnum'' is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, peat 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'. These peat accumulations then provide habitat for a wide array of peatland plants, including sedges and Calcifuges, ericaceous shrubs, as well as orchids and carnivorous plant ...

Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.

Takakia
''Takakia'' is a genus of two species of mosses known from western North America and central and eastern Asia. The genus is placed as a separate family, order and class among the mosses. It has had a history of uncertain placement, but the discovery of sporophytes clearly of the moss-type firmly supports placement with the mosses. Discovery ''Takakia'' was discovered in the Himalayas and described by William Mitten in 1861. It was originally described simply as a new liverwort species (''Lepidozia ceratophylla'')Renzaglia, K. S., K. D. McFarland, & D. K. Smith. 1997. Anatomy and ultrastructure of the sporophyte of ''Takakia ceratophylla'' (Bryophyta). ''American Journal of Botany'' 84(10): 1337–1350. within an existing genus, and it was thus long overlooked. The discovery of similar odd plants in the mid-20th century by Dr. Noriwo Takaki (1915–2006) in Japan sparked more interest. The many unusual features of these plants led to the establishment in 1958 of the speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
