Please answer the following question: Information: - A bog is a wetland that accumulates peat, a deposit of dead plant materialoften mosses, and in a majority of cases, sphagnum moss. It is one of the four main types of wetlands. Other names for bogs include mire, quagmire, and muskeg; alkaline mires are called fens. They are frequently covered in ericaceous shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink. - 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 (first collected in 1987). A. leucobryoides differs from the Sphagnaceae family 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 1999. - A cell wall is a structural layer surrounding some types of cells, situated outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism. Cell walls are present in most prokaryotes except mycoplasma bacteria, in algae, plants and fungi but rarely in other eukaryotes including animals. A major function is to act as pressure vessels, preventing over-expansion of the cell when water enters. - Magnesium is a chemical element with symbolMg and atomic number12. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (Group 2, or alkaline earth metals) of the periodic table: all Group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure. - Hydrogen is a chemical element with chemical symbolH and atomic number1. With an atomic weight of , hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Non-remnant stars are mainly composed of hydrogen in the plasma state. The most common isotope of hydrogen, termed "protium" (name rarely used, symbol H), has one proton and no neutrons. - Calcium is a chemical element with symbolCa and atomic number20. Calcium is a soft gray Group 2 alkaline earth metal, fifth-most-abundant element by mass in the Earth's crust. The ion Ca is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate. Free calcium metal is too reactive to occur in nature. Calcium is produced in supernova nucleosynthesis. - Sphagnum is a genus of approximately 380 accepted species of mosses, commonly known as peat moss. Accumulations of "Sphagnum" can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 1626 times as much water as their dry weight, depending on the species. The empty cells help retain water in drier conditions. Hence, as sphagnum moss grows, it can slowly spread into drier conditions, forming larger mires, both raised bogs and blanket bogs. These peat accumulations then provide habitat for a wide array of peatland plants, including sedges and ericaceous shrubs, as well as orchids and carnivorous plants. "Sphagnum" and the peat formed from it do not decay readily because of the phenolic compounds embedded in the moss's cell walls. In addition, bogs, like all wetlands, develop anaerobic soil conditions, which produces slower anaerobic decay rather than aerobic microbial action. Peat moss can also acidify its surroundings by taking up cations, such as calcium and magnesium, and releasing hydrogen ions. Under the right conditions, peat can accumulate to a depth of many meters. Different species of "Sphagnum" have different tolerance limits for flooding and pH, so any one peatland may have a number of different "Sphagnum" species. - The Sphagnaceae is a family of moss with only one living genus "Sphagnum". - Peat, also called turf, is an accumulation of partially decayed vegetation or organic matter that is unique to natural areas called peatlands, bogs, or mires. The peatland ecosystem is the most efficient carbon sink on the planet because peatland plants capture the CO which is naturally released from the peat, thus maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal peatlands". One of the most common components is "Sphagnum" moss (peat moss), although many other plants can contribute. Soils that contain mostly peat are known as histosols. Peat forms in wetland conditions, where flooding obstructs flows of oxygen from the atmosphere, slowing rates of decomposition. - The Sphagnopsida includes a single subclass Sphagnidae , with two orders . The order Sphagnales contains four living genera : Sphagnum , with all but three of the species , and Ambuchanania , Eosphagnum , and Flatbergium , each with a single species . The Protosphagnales contains a single fossil species . - Tasmania (abbreviated as Tas and known colloquially as "Tassie") is an island state of the Commonwealth of Australia. It is located to the south of the Australian mainland, separated by Bass Strait. The state encompasses the main island of Tasmania, the 26th-largest island in the world, and the surrounding 334 islands. The state has a population of around 518,500, just over forty percent of which resides in the Greater Hobart precinct, which forms the metropolitan area of the state capital and largest city, Hobart. - The Sphagnales is an order of moss with only four living genera: "Ambuchanania", "Eosphagnum", "Flatbergium", and "Sphagnum". - Mosses are small flowerless plants that typically grow in 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. - Blanket bog or blanket mire, also known as featherbed bog, is an area of peatland, forming where there is a climate of high rainfall and a low level of evapotranspiration, allowing peat to develop not only in wet hollows but over large expanses of undulating ground. The blanketing of the ground with a variable depth of peat gives the habitat type its name. Blanket bogs are found extensively throughout the northern hemisphere - well-studied examples are found in Ireland and Britain, but vast areas of the Russian and North American tundra also qualify as blanket bogs. - Carnivorous plants are plants that derive some or most of their nutrients (but not energy) from trapping and consuming animals or protozoans, typically insects and other arthropods. Carnivorous plants have adapted to grow in places with high light where the soil is thin or poor in nutrients, especially nitrogen, such as acidic bogs and rock outcroppings. Charles Darwin wrote "Insectivorous Plants", the first well-known treatise on carnivorous plants, in 1875. What object entity has the relation of 'parent taxon' with the subject 'sphagnopsida'?
