Egå Engsø
Egå Engsø () is an artificial lake and wetland site located in the north of the town of Aarhus between Vejlby, Risskov and Lystrup. Engsø means 'meadow lake' and Egå means 'oak stream', referring to the stream that drains the lake into the Aarhus bay. The lake area is bordered by the Djursland motorway to the north and the Aarhus- Grenaa railway and the municipal heating pipes from Studstrup Power Station to the south and west. Background Egå Engsø was created by re-flooding meadows on land previously drained in the 1950s for agricultural use. By the 1990s the water quality and natural ecosystem in and around the Egå river into which the site drained had declined due to the effect of nitrate fertilizer (eutrophication) use, through intensive farming in the area. Aarhus Municipality, Aarhus County and the Danish Forest and Nature Agency resolved to construct the lake as part of Vandmiljøplan II (English: ''Action Plan for the Aquatic Environment II'') from 1998 to red ...

Midtjylland
The Central Denmark Region (), or more directly translated as the Central Jutland Region and sometimes simply Mid-Jutland, is an administrative region of Denmark established on 1 January 2007 as part of the 2007 Danish municipal reform. The reform abolished the traditional counties (''amter'') and replaced them with five new administrative regions. At the same time, smaller municipalities were merged into larger units, cutting the total number of municipalities from 271 to 98. The reform diminished the power of the regional level dramatically in favour of the local level and the national government in Copenhagen. The Central Denmark Region comprises 19 municipalities. Toponymy The Danish name of the region means "Region of Mid Jutland" and describes the location in the central part of the Jutland peninsula, in contrast to Northern Jutland and Southern Jutland (which, together with Funen and some smaller islands, forms the Region of Southern Denmark).

Meadows
A meadow ( ) is an open habitat or field, vegetated by grasses, herbs, and other non-woody plants. Trees or shrubs may sparsely populate meadows, as long as they maintain an open character. Meadows can occur naturally under favourable conditions but are often artificially created from cleared shrub or woodland for the production of hay, fodder or livestock. Meadow habitats as a group are characterized as semi-natural grasslands, meaning that they are largely composed of species native to the region, with only limited human intervention. Meadows attract a multitude of wildlife and support flora and fauna that could not thrive in other habitats. They are ecologically important since they provide areas for animal courtship displays, nesting, food gathering, pollinating insects, and sometimes sheltering if the vegetation is high enough. Intensified agricultural practices (too frequent mowing, use of mineral fertilizers, manure and insecticides) may lead to declines in the abun ...

East Jutland Fjorde
East is one of the four cardinal directions or points of the compass. It is the opposite direction from west and is the direction from which the Sun rises on the Earth. Etymology As in other languages, the word is formed from the fact that east is the direction where the Sun rises: ''east'' comes from Middle English ''est'', from Old English ''ēast'', which itself comes from the Proto-Germanic *''aus-to-'' or *''austra-'' "east, toward the sunrise", from Proto-Indo-European *aus- "to shine," or "dawn", cognate with Old High German ''*ōstar'' "to the east", Latin ''aurora'' 'dawn', and Greek ''ēōs'' 'dawn, east'. Examples of the same formation in other languages include Latin oriens 'east, sunrise' from orior 'to rise, to originate', Greek ανατολή anatolé 'east' from ἀνατέλλω 'to rise' and Hebrew מִזְרָח mizraḥ 'east' from זָרַח zaraḥ 'to rise, to shine'. ''Ēostre'', a Germanic goddess of dawn, might have been a personification of both da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Tern
The black tern (''Chlidonias niger'') is a small tern generally found in or near inland water that breeds in Europe, Palearctic, Western Asia and North America. In winter the birds migrate to coastal areas of Africa and South America. Taxonomy The black tern was Species description, formally described in 1758 by the Swedish naturalist Carl Linnaeus in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae'' under the binomial nomenclature, binomial name ''Sterna nigra''. Linnaeus specified the type location (biology), type location as Europe but it is now restricted to Uppsala in Sweden. The black tern is now one of four species placed in the genus ''Chlidonias'' that was introduced in 1822 by the French naturalist Constantine Samuel Rafinesque, Constantine Rafinesque. The genus name is from Ancient Greek ''khelidonios'', "swallow-like", from ''khelidon'', "swallow": another old English name for the black tern is "carr (i.e. lake) swallow". The species nam ...

Ferruginous Duck
The ferruginous duck (''Aythya nyroca''), also known as ferruginous pochard, common white-eye or white-eyed pochard, is a medium-sized diving duck from Eurosiberia. The scientific name is derived from the Ancient Greek word, (), an unknown seabird mentioned by authors including Hesychius and Aristotle, and the Russian word, (), the Russian word for pochard, which occurs in the bird's Russian common name. Description The breeding male is a rich, dark chestnut on the head, breast and flanks with contrasting pure white undertail coverts. In flight the white belly and underwing patch are visible. The females are duller and browner than the males. The male has a yellow eye and the females have a dark eye. Habitat The ferruginous duck prefers quite shallow fresh waterbodies with rich submerged and floating vegetation with dense stands of emergent vegetation on the margins. In some areas it will use saline or brackish pools or wetlands. On passage and wintering will also frequen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Spoonbill
The Eurasian spoonbill (''Platalea leucorodia''), or common spoonbill, is a wading bird of the ibis and spoonbill family Threskiornithidae, native to Europe, Africa and Asia. The species is partially migratory with the more northerly breeding populations mostly migrating south for the winter. Taxonomy The Eurasian spoonbill was Species description, formally described in 1758 by the Swedish naturalist Carl Linnaeus in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae'' under the current binomial nomenclature, binomial name ''Platalea leucorodia''. Linnaeus cited works by earlier authors including the description and illustration by the English naturalist Eleazar Albin that was published in 1734. Linnaeus specified the type locality (biology), type locality as Europe but restricted it to Sweden in 1761. The genus name ''Platalea'' is Latin and means "broad", referring to the distinctive shape of the bill; the specific epithet ''leucorodia'' is from Ancient G ...

White Stork
The white stork (''Ciconia ciconia'') is a large bird in the stork family, Ciconiidae. Its plumage is mainly white, with black on the bird's wings. Adults have long red legs and long pointed red beaks, and measure on average from beak tip to end of tail, with a wingspan. The two subspecies, which differ slightly in size, breed in Europe north to Finland, northwestern Africa, Palearctic east to southern Kazakhstan and southern Africa. The white stork is a long-distance migrant, wintering in Africa from tropical Sub-Saharan Africa to as far south as South Africa, or on the Indian subcontinent. When migrating between Europe and Africa, it avoids crossing the Mediterranean Sea and detours via the Levant in the east or the Strait of Gibraltar in the west, because the air thermals on which it depends for soaring do not form over water. A carnivore, the white stork eats a wide range of animal prey, including insects, fish, amphibians, reptiles, small mammals and small birds. It take ...

Short-eared Owl
The short-eared owl (''Asio flammeus'') is a widespread grassland species in the family Strigidae. Owls belonging to genus ''Asio'' are known as the eared owls, as they have tufts of feathers resembling mammalian ears. These "ear" tufts may or may not be visible. The short-eared owl will display its tufts when in a defensive pose, although its very short tufts are usually not visible. The short-eared owl is found in open country and grasslands. Taxonomy The short-eared owl was formally described in 1763 by the Lutheran bishop Erik Pontoppidan under the binomial name ''Strix flammea''. The specific epithet is from the Latin ''flammeus'' meaning "flammulated" or "flame-coloured". This owl is now placed with seven other species in the genus ''Asio'' that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. Eleven subspecies are recognised: * ''A. f. flammeus'' – ( Pontoppidan, 1763): the nominate subspecies, found in North America, Europe, North Africa and ...

Indicator Species
A bioindicator is any species (an indicator species) or group of species whose function, population, or status can reveal the qualitative status of the environment. The most common indicator species are animals. For example, copepods and other small water crustaceans that are present in many water body, water bodies can be monitored for changes (biochemical, physiological, or behavioural) that may indicate a problem within their ecosystem. Bioindicators can tell us about the cumulative effects of different pollution, pollutants in the ecosystem and about how long a problem may have been present, which Water pollution#Measurement, physical and chemical testing cannot. A biological monitor or biomonitor is an organism that provides quantitative property, quantitative information on the quality of Environment (biophysical), the environment around it. Therefore, a good biomonitor will indicate the presence of the pollutant and can also be used in an attempt to provide additional inform ...

Carcinogenic
A carcinogen () is any agent that promotes the development of cancer. Carcinogens can include synthetic chemicals, naturally occurring substances, physical agents such as ionizing and non-ionizing radiation, and Biological agent, biologic agents such as viruses and carcinogenic bacteria, bacteria. Most carcinogens act by creating mutations in DNA that disrupt a cell's normal processes for regulating growth, leading to uncontrolled cellular proliferation. This occurs when the cell's DNA repair processes fail to identify DNA damage allowing the defect to be passed down to daughter cells. The damage accumulates over time. This is typically a multi-step process during which the regulatory mechanisms within the cell are gradually dismantled allowing for unchecked Cell division, cellular division. The specific mechanisms for carcinogenic activity is unique to each agent and cell type. Carcinogens can be broadly categorized, however, as activation-dependent and activation-independent ...

Symphytum Officinale
''Symphytum officinale'' is a perennial flowering plant in the family Boraginaceae. Along with thirty four other species of ''Symphytum'', it is known as comfrey (from the Latin confervere to 'heal' or literally to 'boil together', referring to uses in ancient traditional medicine). Internal or long-term topical use of comfrey is discouraged due to its strong potential to cause liver toxicity. To differentiate it from other members of the genus ''Symphytum'', this species is known as common comfrey or true comfrey. Other English names include boneset, knitbone, consound, and slippery-root. It is native to Europe, growing in damp, grassy places. It is found throughout Ireland and Britain on river banks and ditches. It occurs in North America as an introduced species and weed. The flowers are mostly visited by bumblebees. History Over centuries, comfrey was cultivated in Asia, Europe, and the United Kingdom as a vegetable and herbal medicine.
