Ewartia Planchonii
''Ewartia planchonii'', commonly known as creeping cushionherb, is an endemic herb to alpine areas of Tasmania. ''E. planchonii'' is commonly found in the western highlands of Tasmania. The ''Ewartia'' genus is described as cushion plants/herbs due to the characteristic growth habits of low growing, highly compact mats which are made up of highly packed stems. These mats are slow-growing and are often located in soils that contain low nutrients. Description ''Ewartia planchonii'' is a sprawling herb which forms mat-like ground coverage over rocky alpine landscapes. Leaves are densely tufted, overlapping along the stem, obovately shaped and 3-6mm long. The leaves are also covered by soft hairs which whiten with age. Flowerheads are ovoid in shape and open up flat to 7-8mm long, brownish/ yellow and lack the usual petal-like bracts. Flowering occurs over the summer months to increase chances of pollination.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tasmanian Cushion Plants
Tasmanian cushion plants are low growing, highly compact, woody, spreading mats that can grow up to 3 m in diameter, located mainly on the island of Tasmania. These mats are made up of tightly packed stems that grow at the same rate so that no apical rosettes protrude above the rest. The term cushion plant refers to a characteristic growth habit adopted by various species from a range of families to adapt to alpine and subalpine environments and areas of high latitude. They are adapted to grow in low nutrient areas and typically have deep taproots. Cushion plants are very slow growing and do not grow high above ground; mounds typically remain under 30 cm high. Underneath the living surface of the cushion, the plants either allow dead leaves to persist or produce non-photosynthetic material, resulting in an insulating effect. Floristics of Tasmanian cushion plant community Six families, including seven species, of cushion plants occur in Tasmania, and one additional family and ...

Herbfield
Herbfields are plant communities dominated by herbaceous plants, especially forbs and grasses. They are found where climatic conditions do not allow large woody plants to grow, such as in subantarctic and alpine tundra Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated alpine climate, harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alp ... environments. Herbfield is defined in New South Wales (Australia) government legislation as native vegetation that predominantly does not contain an over-storey or a mid-storey and where ground cover is dominated by non-grass species. The New Zealand Department of Conservation has described herbfield vegetation as that in which the cover of herbs in the canopy is 20–100%, and in which herb cover is greater than that of any other growth form, or of bare ground.Lux et al. (2009). Various kinds of herbfield i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Abundance
In ecology, local abundance is the relative representation of a species in a particular ecosystem. It is usually measured as the number of individuals found per sample. The ratio of abundance of one species to one or multiple other species living in an ecosystem is referred to as relative species abundances. Both indicators are relevant for computing biodiversity. A variety of sampling methods are used to measure abundance. For larger animals, these may include spotlight counts, track counts and roadkill counts, as well as presence at monitoring stations. In many plant communities the abundances of plant species are measured by plant cover, i.e. the relative area covered by different plant species in a small plot. Abundance is in simplest terms usually measured by identifying and counting every individual of every species in a given sector. It is common for the distribution of species to be skewed so that a few species take up the bulk of individuals collected. Relative spec ...

Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, 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 orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. '' Sphagnum'' moss, also called peat moss, is one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ben Lomond (Tasmania)
Ben Lomond is a mountain in the north-east of Tasmania, Australia. The mountain is composed of a central massif with an extensive plateau above and high outlier peaks projecting from the mountain. The highest feature on the plateau is the unimposing summit of Legges Tor, at 1572 m, on the northern aspect of the plateau. The southern end of the plateau is dominated by Stacks Bluff, , which is an imposing feature that drops away to a cliffline above the surrounding foothills. The prominent outlier peaks of Ragged Jack (), Mensa Moor () and Tower Hill () surround the plateau. Ben Lomond is east of Launceston in the Ben Lomond National Park. Tasmania's premier Alpine skiing operations are located at Ben Lomond with downhill skiing facilities in the State. Its accessibility from Launceston, together with the existence of a ski village on the plateau make Ben Lomond an all year round favourite for tourists and hikers. Access to the village and summit can be made via se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asterales Of Australia
Asterales () is an order of dicotyledonous flowering plants that includes the large family Asteraceae (or Compositae) known for composite flowers made of florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals (as found in the rosids). The order is cosmopolitan (plants found throughout most of the world including desert and frigid zones), and includes mostly herbaceous species, although a small number of trees (such as the '' Lobelia deckenii'', the giant lobelia, and '' Dendrosenecio'', giant groundsels) and shrubs are also present. Asterales are organisms that seem to have evolved from one common ancestor. Asterales share characteristics on morphological and biochemical levels. Synapomorphies (a character that is shared by two or more groups through evolutionary development) include the presence in the plants of oligosacch ...
