Fen Violet
''Viola elatior'', the fen violet, is a species of violet native to central and northern Europe and northern Asia. In the British Isles it is very rare, occurring in a few fens in England and near the western coast of Ireland. Description ''Viola elatior'' grows to a height of from a creeping rhizome, with narrow, triangular leaves across. The flowers are produced in late spring to early summer, diameter, pale bluish or yellowish-white with a short, greenish or yellowish spur. The petals are rounded and broad in relation to their width. Distribution and habitat ''Viola elatior'' occurs in native to central and northern Europe and northern Asia. Its habitat is confined to very local damp, lime-rich places, in long herbage (fens and limy marshes). The plant is fussy about where it grows; seeds germinates in the spring on moist bare patches of base-rich peaty soil, but the seedlings only become established if the soil surface becomes drier. Most seeds germinate in close proximit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Christian Daniel Von Schreber
Johann Christian Daniel von Schreber (17 January 1739 in Weißensee, Thuringia – 10 December 1810 in Erlangen), often styled J.C.D. von Schreber, was a German naturalist. Career He was appointed professor of'' materia medica'' at the University of Erlangen in 1769. In 1774, he began writing a multivolume set of books entitled ''Die Säugethiere in Abbildungen nach der Natur mit Beschreibungen'', which focused on the mammals of the world. Many of the animals included were given a scientific name for the first time, following the binomial system of Carl Linnaeus. From 1791 until his death in 1810, he was the president of the German Academy of Sciences Leopoldina. He was elected a member of the Royal Swedish Academy of Sciences in 1787. In April 1795, he was elected a Fellow of the Royal Society Numerous honors were bestowed on him, including the office of an imperial count palatine. Schreber also wrote on entomology, notably ''Schreberi Novae Species Insectorvm''. His herbar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soil
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem. Most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Finland
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea ...

County Fermanagh
County Fermanagh ( ; ) is one of the thirty-two counties of Ireland, one of the nine counties of Ulster and one of the six counties of Northern Ireland. The county covers an area of 1,691 km2 (653 sq mi) and has a population of 61,805 as of 2011. Enniskillen is the county town and largest in both size and population. Fermanagh is one of four counties of Northern Ireland to have a majority of its population from a Catholic background, according to the 2011 census. Geography Fermanagh is situated in the southwest corner of Northern Ireland. It spans an area of 1,851 km2 (715 sq; mi), accounting for 13.2% of the landmass of Northern Ireland. Nearly a third of the county is covered by lakes and waterways, including Upper and Lower Lough Erne and the River Erne. Forests cover 14% of the landmass (42,000 hectares). It is the only county in Northern Ireland that does not border Lough Neagh. The county has three prominent upland areas: * the expansive We ...

Turlough (lake)
A turlough (turloch or turlach in Irish), is a seasonal or periodic water body found mostly in limestone karst areas of Ireland, west of the River Shannon. The name comes from the Irish ''tur'', meaning "dry", and ''loch'', meaning "lake". The water bodies fill and empty with the changes in the level of the water table, usually being very low or empty during summer and autumn and full in the winter. As groundwater levels drop the water drains away underground through cracks in the karstic limestone. Turloughs are almost unique to Ireland, although there is one example in Wales, Pant-y-Llyn at Cernydd Carmel near Llandeilo. They are of great interest to many scientists: geomorphologists are interested in how turloughs were formed, hydrologists try to explain what makes turloughs flood, botanists study the unusual vegetation which covers the turlough floor, and zoologists study the animals associated with the turloughs. Locations Turloughs are mostly found on the central lowla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lough Erne
Lough Erne ( , ) is the name of two connected lakes in County Fermanagh, Northern Ireland. It is the second-biggest lake system in Northern Ireland and Ulster, and the fourth biggest in Ireland. The lakes are widened sections of the River Erne, which flows north and then curves west into the Atlantic. The smaller southern lake is called the Upper Lough as it is higher up the river. The bigger northern lake is called the Lower Lough or Broad Lough. The town of Enniskillen lies on the short stretch of river between the lakes. The lake has more than 150 islands, along with many coves and inlets. The River Erne is 80 miles (129 km) long and drains an area of about 1,680 square miles (4,350 km2). Name, mythology and folklore Lough Erne (Loch Éirne) appears to be named after an ancient population group called the Érainn, or after a goddess from which the Érainn took their name.Roulston, William J.

Great Fen Project
The Great Fen is a habitat restoration project being undertaken on The Fens in the county of Cambridgeshire in England. It is one of the largest restoration projects in the country, and aims to create a 3,700 hectare wetland and aims to connect Woodwalton Fen National Nature Reserve (NNR), Holme Fen NNR and other nature reserves to create a larger site with conservation benefits for wildlife and socio-economic benefits for people. This is a long-term project managed in partnership by the Environment Agency, Huntingdonshire District Council, Middle Level Commissioners, Natural England and the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire (WTBCN). Woodwalton Fen, Holme Fen and Darlows Farm are managed by Natural England, while the WTBCN manages the Countryside Centre for educational and community work, together with Corney's Farm, New Decoy Farm, Old Decoy Farm, Engine Farm, Rymes Reedbeds (which has a bird hide), and Kesters Docking.

The Fens
The Fens, also known as the , in eastern England are a naturally marshy region supporting a rich ecology and numerous species. Most of the fens were drained centuries ago, resulting in a flat, dry, low-lying agricultural region supported by a system of drainage channels and man-made rivers ( dykes and drains) and automated pumping stations. There have been unintended consequences to this reclamation, as the land level has continued to sink and the dykes have been built higher to protect it from flooding. Fen is the local term for an individual area of marshland or former marshland. It also designates the type of marsh typical of the area, which has neutral or alkaline water and relatively large quantities of dissolved minerals, but few other plant nutrients. The Fens are a National Character Area, based on their landscape, biodiversity, geodiversity and economic activity. The Fens lie inland of the Wash, and are an area of nearly in Lincolnshire, Cambridgeshire, and Norfol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viola (plant)
''Viola'' is a genus of flowering plants in the violet family Violaceae. It is the largest genus in the family, containing between 525 and 600 species. Most species are found in the temperate Northern Hemisphere; however, some are also found in widely divergent areas such as Hawaii, Australasia, and the Andes. Some ''Viola'' species are perennial plants, some are annual plants, and a few are small shrubs. Many species, varieties and cultivars are grown in gardens for their ornamental flowers. In horticulture the term pansy is normally used for those multi-colored, large-flowered cultivars which are raised annually or biennially from seed and used extensively in bedding. The terms viola and violet are normally reserved for small-flowered annuals or perennials, including the wild species. Description Annual or perennial caulescent or acaulescent (with or without a visible plant stem above the ground) herbs, shrubs or very rarely treelets. In acaulescent taxa the foliage and flower ...

British Isles
The British Isles are a group of islands in the North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner and Outer Hebrides, the Northern Isles, and over six thousand smaller islands."British Isles", ''Encyclopædia Britannica''. They have a total area of and a combined population of almost 72 million, and include two sovereign states, the Republic of Ireland (which covers roughly five-sixths of Ireland), and the United Kingdom of Great Britain and Northern Ireland. The Channel Islands, off the north coast of France, are normally taken to be part of the British Isles, even though they do not form part of the archipelago. The oldest rocks are 2.7 billion years old and are found in Ireland, Wales and the northwest of Scotland. During the Silurian period, the north-western regions collided with the south-east, which had been part of a separate continental landmass. The ...
