Karpatiosorbus Admonitor
''Karpatiosorbus admonitor'', previously classified as ''Sorbus admonitor'' and also called the no parking whitebeam, is a species of whitebeam tree found in Devon, United Kingdom. It is known only from the Watersmeet Valley at Lynton, with two stray plants growing on the coast above Sillery Sands, Countisbury. Discovery Its unusual name derives from the location of the first tree to be found (not the type specimen) – by a lay-by near Watersmeet in North Devon, with a "no parking" sign nailed to the tree. Although first recognised as a distinct variety in the 1930s (by the botanist E. F. Warburg) because of its strongly lobed leaves, it was only accorded species status in 2009, after various biochemical analyses. It is believed at least 110 individuals of the species exist and represent a stable population. The leaves of the no parking whitebeam have more accentuated lobes than the Devon whitebeam, of which it was thought before to be a variety. The research project that n ...

Whitebeam
The whitebeams are members of the family Rosaceae, comprising subgenus ''Aria'' (or, according to some authorities, its own genus) of genus ''Sorbus'', and hybrids involving species of this subgenus and members of subgenera ''Sorbus'', ''Torminaria'' and ''Chamaemespilus''. They are deciduous trees with simple or lobed leaves, arranged alternately. They are related to the rowans (''Sorbus'' subgenus ''Sorbus''), and many of the endemic restricted-range apomictic microspecies of whitebeam in Europe are thought to derive from hybrids between ''S. aria'' and the European rowan ''S. aucuparia''; some are also thought to be hybrids with the wild service tree ''S. torminalis'', notably the service tree of Fontainebleau ''Sorbus latifolia'' in French woodlands. The best known species is the common whitebeam '' Sorbus aria'', a columnar tree which grows to tall by broad, with clusters of white flowers in spring followed by speckled red berries in autumn (fall).

The Independent
''The Independent'' is a British online newspaper. It was established in 1986 as a national morning printed paper. Nicknamed the ''Indy'', it began as a broadsheet and changed to tabloid format in 2003. The last printed edition was published on Saturday 26 March 2016, leaving only the online edition. The newspaper was controlled by Tony O'Reilly's Irish Independent News & Media from 1997 until it was sold to the Russian oligarch and former KGB Officer Alexander Lebedev in 2010. In 2017, Sultan Muhammad Abuljadayel bought a 30% stake in it. The daily edition was named National Newspaper of the Year at the 2004 British Press Awards. The website and mobile app had a combined monthly reach of 19,826,000 in 2021. History 1986 to 1990 Launched in 1986, the first issue of ''The Independent'' was published on 7 October in broadsheet format.Dennis Griffiths (ed.)

Chromosome
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated ( S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lynmouth
Lynmouth is a village in Devon, England, on the northern edge of Exmoor. The village straddles the confluence of the West Lyn and East Lyn rivers, in a gorge below Lynton, which was the only place to expand to once Lynmouth became as built-up as possible. The villages are connected by the Lynton and Lynmouth Cliff Railway, which works two cable-connected cars by gravity, using water tanks. The two villages are a civil parish governed by Lynton and Lynmouth Town Council. The parish boundaries extend southwards from the coast, and include hamlets such as Barbrook and small moorland settlements such as East Ilkerton, West Ilkerton and Shallowford. The South West Coast Path and Tarka Trail pass through, and the Two Moors Way runs from Ivybridge in South Devon to Lynmouth; the Samaritans Way South West runs from Bristol to Lynton, and the Coleridge Way from Nether Stowey to Lynmouth. Lynmouth was described by Thomas Gainsborough, who honeymooned there with his bride Margare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower ( abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Karpatiosorbus Latifolia
''Karpatiosorbus latifolia'' (the broad-leaved whitebeam or service tree of Fontainebleau; French: ''alisier de Fontainebleau'') is a species of whitebeam that is endemic to the area around Fontainebleau, south of Paris in France, where it has been known since the early eighteenth century.Rushforth, K.

Vice-counties
A vice-county (vice county or biological vice-county) is a geographical division of the British Isles used for the purposes of biological recording and other scientific data-gathering. It is sometimes called a Watsonian vice-county as vice-counties were introduced for Great Britain, its offshore islands, and the Isle of Man, by Hewett Cottrell Watson who first used them in the third volume of his ''Cybele Britannica'' published in 1852. Watson's vice-counties were based on the ancient counties of Britain, but often subdividing these boundaries to create smaller, more uniform units, and considering exclaves to be part of the surrounding vice-county. In 1901 Robert Lloyd Praeger introduced a similar system for Ireland and its off-shore islands. Vice-counties are the "standard geographical area for county based ..recording". They provide a stable basis for recording using similarly sized units, and, although National Grid-based reporting has grown in popularity, vice-counties r ...

Scree
Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. Talus deposits typically have a concave upwards form, where the maximum inclination corresponds to the angle of repose of the mean debris particle size. The exact definition of scree in the primary literature is somewhat relaxed, and it often overlaps with both ''talus'' and ''colluvium''. The term ''scree'' comes from the Old Norse term for landslide, ''skriða'', while the term ''talus'' is a French word meaning a slope or embankment. In high-altitude arctic and subarctic regions, scree slopes and talus deposits are typically adjacent to hills and river valleys. These steep slopes usually originate from late-Pleistocene periglacial processes. Notable scree sites in Eastern North America include the Ice Caves at White Rocks National Recreation Area in southern Ve ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malinae
Malinae is the name for the apple subtribe in the rose family, Rosaceae. This name is required by the International Code of Nomenclature for algae, fungi, and plants, which came into force in 2011 (article 19) for any group at the subtribe rank that includes the genus ''Malus'' but not either of the genera ''Rosa'' or ''Amygdalus''. The group includes a number of plants bearing commercially important fruits, such as apples and pears, while others are cultivated as ornamentals. The tribe consists exclusively of shrubs and small trees characterised by a pome, a type of accessory fruit that does not occur in other Rosaceae, and by a basal haploid chromosome A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are ... count of 17 (instead of 7, 8, 9, or 15 as in the other Rosaceae).
