Sorbus Arranensis
''Hedlundia arranensis'', sometimes referred to as the Scottish or Arran whitebeam, is a species of plant in the family Rosaceae. It is endemic to the island of Arran in Scotland. Range and habitat The species is threatened by habitat loss and only 283 ''Hedlundia arranensis'' were recorded as mature trees in 1980. They are protected in Glen Diomhan off Glen Catacol, which was formerly part of a National Nature Reserve; although this designation was removed in 2011 the area continues to form part of a designated Site of Special Scientific Interest (SSSI), and is monitored by staff from NatureScot. In its native states its distribution is restricted to Abhainn Bheag (Uisge Solus), Glen Diomhan (and tributary), Glen Catacol, Allt nan Calman, ''Allt Dubh'', Gleann Easan Biorach and Glen Iorsa (''Allt-nan-Champ''). The trees are found in small remnants of woodland on inaccessible steep slopes, and grow on acidic soils. ''Hedlundia arranensis'' evoked most collecting interest in ...

Cloning
Cloning is the process of producing individual organisms with identical genomes, either by natural or artificial means. In nature, some organisms produce clones through asexual reproduction; this reproduction of an organism by itself without a mate is known as parthenogenesis. In the field of biotechnology, cloning is the process of creating cloned organisms of Cell (biology), cells and of DNA fragments. The artificial cloning of organisms, sometimes known as reproductive cloning, is often accomplished via somatic-cell nuclear transfer (SCNT), a cloning method in which a viable embryo is created from a somatic cell and an egg cell. In 1996, Dolly (sheep), Dolly the sheep achieved notoriety for being the first mammal cloned from a somatic cell. Another example of artificial cloning is molecular cloning, a technique in molecular biology in which a single living cell is used to clone a large population of cells that contain identical DNA molecules. In bioethics, there are a vari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Scotland
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...

Hedlundia
''Hedlundia'' is a genus of plants in the rose family (biology), family (of Rosaceae). They are shrubs or small trees that have a Hybrid (biology), hybrid origin involving crosses between ''Whitebeam, Aria'' and ''Sorbus'' sensu stricto. There are about 48 species are distributed across central, western and southern Europe, Scandinavia, Turkey, the Caucasus, Crimea, and also central Asia. The term ''Hedlundia'' was published in 2017. Description ''Hedlundia'' species are small trees or shrubs, with simple leaves, pinnatilobate (having lobes arranged in a pinnate manner) or basally Pinnation, pinnate with 1–2(–3) leaflets. They are white- or greenish-grey-tomentose (covered with dense, matted, woolly hairs) beneath, with 7–15 pairs of lateral veins, with small to prominent, long, sub-acute to obtuse lobes with a variable number of teeth. They have flowers with white petals and 2–3 Gynoecium, styles. The fruit is medium-sized, orange-red to crimson in colour, with few to sp ...

Flora Of The United Kingdom
The flora of Great Britain and Ireland is one of the best documented in the world. There are 1390 native species and over 1100 well-established non-natives documented on the islands. A bibliographic database of the species has been compiled by the Botanical Society of Britain and Ireland. The lists (spread across multiple pages due to size) give an English name and a scientific name for each species, and two symbols are used to indicate status (e for extinct species, and * for introduced species). * List of the vascular plants of Britain and Ireland (ferns and allies) covers ferns and allies (Lycopodiopsida, Equisetopsida and Pteridopsida) * List of the vascular plants of Britain and Ireland (conifers) covers the conifers ( Pinopsida) The remaining parts cover the flowering plants ( Magnoliopsida): * List of the vascular plants of Britain and Ireland (dicotyledons) * List of the vascular plants of Britain and Ireland (Rosaceae), covering the dicotyledon family Rosaceae * L ...

Arran Whitebeams
The Arran whitebeams are species of whitebeam endemic to the island of Arran, Ayrshire, Scotland. Status These trees, sometimes called the Scottish or Arran whitebeam (''Sorbus arranensis''), the bastard mountain ash or cut-leaved whitebeam (''Sorbus pseudofennica'') and the Catacol whitebeam ('' Sorbus pseudomeinichii'') are, if rarity is measured by numbers alone, amongst the most endangered tree species in the world. They are protected in Glen Diomhan off Glen Catacol, which was formerly part of a National Nature Reserve; although this designation was removed in 2011 the area continues to form part of a designated Site of Special Scientific Interest (SSSI). Only 283 Arran whitebeam and 236 cut-leaved whitebeam were recorded as mature trees in 1980, and it is thought that grazing pressures and insect damage are preventing regeneration of the woodland. They are typically trees of the mountain slopes, close to the tree line. However, they will grow at lower altitudes, and th ...

Hedlundia Pseudofennica
''Hedlundia pseudofennica'', also called Arran service-tree or Arran cut-leaved whitebeam, is a species of plant in the family Rosaceae. Endemic to the Isle of Arran in Scotland, it is threatened by habitat loss. It is thought to be a naturally occurring hybrid between '' H. arranensis'' and ''Sorbus aucuparia'', probably with additional backcrossing with ''S. aucuparia''. ''Hedlundia arranensis'' is itself a hybrid between ''Aria rupicola'' and ''S. aucuparia''. Apomixis and hybridization are common in some groups of ''Sorbus'' species.

Sorbus Aucuparia
''Sorbus aucuparia'', commonly called rowan (, also ) and mountain-ash, is a species of deciduous tree or shrub in the rose family. The tree has a slender trunk with smooth bark, a loose and roundish crown, and its leaves are pinnate in pairs of leaflets on a central vein with a terminal leaflet. It blossoms from May to June in dense corymbs of small yellowish white flowers and develops small red pomes as fruit that ripen from August to October and are eaten by many bird species. It is a highly variable species, and botanists have used different Circumscription (taxonomy), definitions of the species to include or exclude trees native to certain areas. A recent definition includes trees native to most of Europe and parts of Asia, as well as northern Africa. The range extends from Madeira, the British Isles and Iceland to Russia and northern China. Unlike many plants with similar distributions, it is not native to Japan. The plant is frost hardy and colonizes disrupted and inacces ...

Holy Isle, Firth Of Clyde
The Holy Island or Holy Isle () is an island in the Firth of Clyde, off the west coast of central Scotland, inside Lamlash Bay on the larger Isle of Arran. The island is around long and around wide. Its highest point is the hill Mullach Mòr. History The island has a long history as a sacred site, with a spring or holy well held to have healing properties, the hermit cave of 6th century monk St Molaise, and evidence of a 13th-century monastery. An old Gaelic name for the island was ''Eilean MoLaise'', Molaise's Island; this is the origin (via ''Elmolaise'' and ''Limolas'') of " Lamlash", the name of the village on Arran that faces Holy Island. Some runic writing is to be found on the roof of St Molaise's cave and a Viking fleet sheltered between Arran and Holy Isle before the Battle of Largs. In 1549, Dean Monro wrote of the "little ile callit the yle of Molass, quherin there was foundit by Johne, Lord of the iles, ane monastry of friars, which is decayit." Current own ...

Aria Rupicola
''Aria rupicola'', commonly known as rock whitebeam, is a rare species of shrub or small tree best known from the British Isles but also reported from Norway, Sweden and Russia. Reaching heights of 10 m,''New Flora of the British Isles''; Clive Stace; Third edition; 2011 printing it grows in rocky woodland, scrub and cliffs, usually on limestone. The species reproduces apomictically (asexually via cloned seeds) and was presumably created by autopolyploidysation of the common whitebeam proper (''Sorbus aria s.str.''). It contains a tetraploidal set of chromosome A chromosome is a package of DNA containing part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome-forming packaging proteins; in eukaryotic cells, the most import ...s (2n=4x=68).
