Skjoldhøjkilen With Holmstrup Mark
Skjoldhøjkilen is a recreational and natural site, in the district of Brabrand in the western part of Aarhus in Denmark. It stretches westwards from Hasle Hills, like a wavy green strip of meadows, small lakes and woodlands. It is 3.5 km long and just as Hasle Hills, it is administered by the self-governing institution 'Hasle Bakker'. Reconstruction The landscape and nature of Skjoldhøjkilen was recently restored and recreated in a series of five construction projects finished in 2005. The projects comprised afforestations, restoration of the stream of Voldbækken, construction of multipurpose rainwater reservoirs, and various road constructions. As a consequence, Skjoldhøjkilen now constitutes a connected woodland area with the newly raised forest of True Skov to the west, thereby constituting a large green wedge of nature cutting its way into the city from the countryside. This is all part of the implementation of Aarhus Municipality's agenda "Aarhus surrounded by fores ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brown Trout
The brown trout (''Salmo trutta'') is a European species of salmonid fish that has been widely introduced into suitable environments globally. It includes purely freshwater populations, referred to as the riverine ecotype, ''Salmo trutta'' morpha ''fario'', a lacustrine ecotype, ''S. trutta'' morpha ''lacustris'', also called the lake trout, and anadromous forms known as the sea trout, ''S. trutta'' morpha ''trutta''. The latter migrates to the oceans for much of its life and returns to fresh water only to spawn. Sea trout in Ireland and Britain have many regional names: sewin in Wales, finnock in Scotland, peal in the West Country, mort in North West England, and white trout in Ireland. The lacustrine morph of brown trout is most usually potamodromous, migrating from lakes into rivers or streams to spawn, although evidence indicates some stocks spawn on wind-swept shorelines of lakes. ''S. trutta'' morpha ''fario'' forms stream-resident populations, typically in alpine stre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corvidae
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, jackdaws, jays, magpies, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family or corvids. Currently, 133 species are included in this family. The genus ''Corvus'', including the crows, rooks, and ravens, makes up over a third of the entire family. Corvids (ravens) are the largest passerines. Corvids display remarkable intelligence for animals of their size, and are among the most intelligent birds thus far studied. Specifically, members of the family have demonstrated self-awareness in mirror tests (European magpies) and tool-making ability (e.g. crows and rooks), skills which until recently were thought to be possessed only by humans and a few other higher mammals. Their total brain-to-body mass ratio is equal to that of non-human great apes and cetaceans, and only slightly lower than that of humans.Birding in India and South AsiaCor ...

Alnus Glutinosa
''Alnus glutinosa'', the common alder, black alder, European alder, European black alder, or just alder, is a species of tree in the family Betulaceae, native to most of Europe, southwest Asia and northern Africa. It thrives in wet locations where its association with the bacterium ''Frankia alni'' enables it to grow in poor quality soils. It is a medium-sized, short-lived tree growing to a height of up to 30 metres (98 feet). It has short-stalked rounded leaves and separate male and female flowers in the form of catkins. The small, rounded fruits are cone-like and the seeds are dispersed by wind and water. The common alder provides food and shelter for wildlife, with a number of insects, lichens and fungi being completely dependent on the tree. It is a pioneer species, colonising vacant land and forming mixed forests as other trees appear in its wake. Eventually common alder dies out of woodlands because the seedlings need more light than is available on the forest floor. I ...

Carr (landform)
A carr is a type of waterlogged wooded terrain that, typically, represents a succession stage between the original reedy marsh and the likely eventual formation of forest in a sub-maritime climate.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984. . Carrs are wetlands that are dominated by shrubs rather than trees. The carr is one stage in a hydrosere: the progression of vegetation beginning from a terrain submerged by fresh water along a river or lake margin. In sub-maritime regions, it begins with reed-marsh. As the reeds decay, the soil surface eventually rises above the water, creating fens that allow vegetation such as sedge to grow. As this progression continues, riparian trees and bushes appear and a carr landscape is created – in effect a wooded fen in a waterlogged terrain. At this stage, overall, unlike the overwhelming acidity of decaying reeds, the pH is not too acidic and the soil is not too deficient in minerals, making a habitat fo ...

European Mole
The European mole (''Talpa europaea'') is a mammal of the order Eulipotyphla. It is also known as the common mole and the northern mole. This mole lives in a tunnel system, which it constantly extends. It uses these tunnels to hunt its prey. Under normal conditions, the displaced earth is pushed to the surface, resulting in the characteristic molehills. It is an omnivore that feeds mainly on earthworms, but also on insects, centipedes and even mice and shrews. Its saliva contains toxins which paralyze earthworms in particular. Taxonomy The Aquitanian mole (''T. aquitania'') was formerly considered conspecific, but was described as a distinct species in 2017. Distribution The European mole has a wide range throughout Europe and westernmost Asia, being found as far north as the United Kingdom and southern Scandinavia, as far south as northern Greece, and as far east as western Siberia. It is the only mole species in most of this range. The Loire River in France was thought to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Tree Frog
The European tree frog (''Hyla arborea'') is a small tree frog. As traditionally defined, it was found throughout much of Europe, Asia and northern Africa,Frost, Darrel R. ''Amphibian Species of the World''. Allen Press, Inc., 1985, p. 126. but based on molecular genetic and other data several populations formerly included in it are now recognized as separate species (for example, '' H. intermedia'' of Italy and nearby, '' H. molleri'' of the Iberian Peninsula, '' H. meridionalis'' of parts of southwestern Europe and northern Africa, and '' H. orientalis'' of parts of Eastern Europe, Turkey and the Black Sea and Caspian Sea regions), limiting the true European tree frog to Europe from France to Poland and Greece.Duellman, William E.

Grey Heron
The grey heron (''Ardea cinerea'') is a long-legged wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water or stalking its prey through the shallows. Standing up to tall, adults weigh from . They have a white head and neck with a broad black stripe that extends from the eye to the black crest. The body and wings are grey above and the underparts are greyish-white, with some black on the flanks. The long, sharply pointed beak is pinkish-yellow and the legs are brown. The birds breed colonially in spring in "heronries", usually building their nests high in trees. A clutch of usually three to five bluish-gree ...

Eurasian Coot
The Eurasian coot (''Fulica atra''), also known as the common coot, or Australian coot, is a member of the rail and crake bird family, the Rallidae. It is found in Europe, Asia, Australia, New Zealand and parts of North Africa. It has a slaty-black body, a glossy black head and a white bill with a white frontal shield. The sexes are similar. Similar looking coot species are found throughout the world, with the largest variety of coot species living in South America. Taxonomy The Eurasian coot was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under its current binomial name ''Fulica atra''. Linnaeus specified the locality as Europe but this is now restricted to Sweden. The binomial name is from Latin: ''Fulica'' means "coot", and ''atra'' means "black". Four subspecies are recognised: * ''F. a. atra'' Linnaeus, 1758 – Europe and north Africa to Japan, India, southeast Asia, Philippines and Borneo * ''F. a. l ...

Duck
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch and German 'to dive'. This word replaced Old English / 'duck', possibly to avoid confusion with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Crested Newt
The northern crested newt, great crested newt or warty newt (''Triturus cristatus'') is a newt species native to Great Britain, northern and central continental Europe and parts of Western Siberia. It is a large newt, with females growing up to long. Its back and sides are dark brown, while the belly is yellow to orange with dark blotches. Males develop a conspicuous jagged crest on their back and tail during the breeding season. The northern crested newt spends most of the year on land, mainly in forested areas in lowlands. It moves to aquatic breeding sites, mainly larger fish-free ponds, in spring. Males court females with a ritualised display and deposit a spermatophore on the ground, which the female then picks up with her cloaca. After fertilisation, a female lays around 200 eggs, folding them into water plants. The larvae develop over two to four months before metamorphosing into terrestrial juveniles (efts). Both larvae and land-dwelling newts mainly feed on different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decli ...
