Phoenix United Mine
Phoenix United Mine is a disused 19th century copper and tin mine in Cornwall, England, UK. Heavy metals left over in the soil from the mining operations have allowed mosses and lichens to flourish, and today the site is a Site of Special Scientific Interest (SSSI), noted for its biological characteristics. History The mine was first worked in 1836 as Cornwall Great United Mines, having previously been mined separately as Clanacombe, Stowes and Wheal Prosper mines. The mine was subsequently bought by James Seccombe in 1842 who renamed it Phoenix Mine/Wheal Phoenix in 1844, finally being called Phoenix United Mine when West Phoenix Mine was incorporated. The mine originally extracted copper, the 1850s being the mine's peak production of the metal, with a work force of 130. By the 1860s the copper reserves were diminishing but consultant mining engineer, William West, bought a controlling share in the company and equipped the mine to extract tin in 1864 after samples showed evide ...

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 ...

Adit
An adit (from Latin ''aditus'', entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins. Construction Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the adit is rarely straight. The use of adits for the extraction of ore is generally called drift mining. Adits can only be driven into a mine where the local topography permits. There will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. Also if the ground is weak, the cost of shoring up a long adit may outweigh its possible advantage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Horseshoe Bat
The greater horseshoe bat (''Rhinolophus ferrumequinum'') is an insectivorous bat of the genus '' Rhinolophus''. Its distribution covers Europe, Northern Africa, Central Asia and Eastern Asia. It is the largest of the horseshoe bats in Europe and is thus easily distinguished from other species. The species is sedentary, typically travelling up to between the winter and summer roosts, with the longest recorded movement being . The frequencies used by this bat species for echolocation lie between 69–83 kHz, have most energy at 81 kHz and have an average duration of 37.4 ms. Description The greater horseshoe bat is the largest horseshoe bat in Europe.Schober, W., E. Grimmberger. 1997. It has a distinctive noseleaf, which has a pointed upper part and a horseshoe-shaped lower part. Its horseshoe noseleaf helps to focus the ultrasound it uses to 'see'. The greater horseshoe bat also has tooth and bone structures that are distinct from that of other rhinolophids. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pioneer Species
Pioneer species are hardy species that are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by wildfire. Pioneer flora Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants.LICHEN BIOLOGY AND THE ENVIRONMENT, LICHENS OF NORTH AMERICA, Sylvia and Stephen Sharnoff/ref> Since some uninhabited land may have thin, poor quality soils with few nutrients, pioneer species are often hardy plants with adaptations such as long roots, root nodes containing Diazotroph, nitrogen-fixing bacteria, and leaves that employ transpiration. Note that they are often photosynthetic plants, as no other source of energy (such as other species) except light energy is often available in the early stages of succession, thus making it less likely for a pioneer species to be non-photosynthetic. The plants that are often pioneer species also tend to be wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ditrichum Cornubicum
''Ditrichum cornubicum'', commonly known as the Cornish path-moss, is a moss endemic to Cornwall, United Kingdom. First discovered in 1963, on a roadside west of Lanner, Cornwall by Jean Paton, it has since been found in two other places within Cornwall. It was published as new to science in 1976. Distribution, habitat and conservation In 1963, a local bryologist Jean Paton, found an unknown specimen at a roadside to the west of Lanner, near Redruth, in west Cornwall. It was on mine spoil used to surface a small roadside lay-by. It has not been re-found at Lanner but two years later, in 1965 she found the same species at a disused copper mine on the south-east edge of Bodmin Moor at Minions. In 1997 David Holyoak found another population nearby at Crow's Nest. A small population discovered in west Cork, Ireland is likely to have been an accidental introduction from Cornwall and appears to have disappeared. The entire world population of this species covers only 0.16msq and it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
