Lowland Heath
Lowland heath is a Biodiversity Action Plan habitat as it is a type of ancient wild landscape. Natural England's Environmental Stewardship scheme describes lowland heath as containing dry heath, wet heath and valley mire communities, usually below in altitude, on acidic soils and shallow peat, typically comprising heathers, gorses, fine grasses, wild flowers and lichens in a complex mosaic. Heathers and other dwarf shrubs usually account for at least 25% of the ground cover. By contrast, ''upland'' heath, which is above in altitude, is called moorland, Dartmoor being an example. Characteristics Lowland heath occurs on a range of acidic pH < 5, impoverished soils that are often sandy and free draining, characteristically .Webb N R, 1986 ''Heathlands''.

Nitrogen Fixation
Nitrogen fixation is a chemical process by which molecular nitrogen (), with a strong triple covalent bond, in the air is converted into ammonia () or related nitrogenous compounds, typically in soil or aquatic systems but also in industry. Atmospheric nitrogen is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms. Biological nitrogen fixation or ''diazotrophy'' is an important microbials mediated process that converts dinitrogen (N2) gas to ammonia (NH3) using the nitrogenase protein complex (Nif). Nitrogen fixation is essential to life because fixed inorganic nitrogen compounds are required for the biosynthesis of all nitrogen-containing organic compounds, such as amino acids and proteins, nucleoside triphosphates and nucleic acids. As part of the nitrogen cycle, it is essential for agriculture and the manufacture of fertilizer. It is also, indirectly, relevant to the manufacture of all nitrogen chemical c ...

Devon
Devon ( , historically known as Devonshire , ) is a ceremonial and non-metropolitan county in South West England. The most populous settlement in Devon is the city of Plymouth, followed by Devon's county town, the city of Exeter. Devon is a coastal county with cliffs and sandy beaches. Home to the largest open space in southern England, Dartmoor (), the county is predominately rural and has a relatively low population density for an English county. The county is bordered by Somerset to the north east, Dorset to the east, and Cornwall to the west. The county is split into the non-metropolitan districts of East Devon, Mid Devon, North Devon, South Hams, Teignbridge, Torridge, West Devon, Exeter, and the unitary authority areas of Plymouth, and Torbay. Combined as a ceremonial county, Devon's area is and its population is about 1.2 million. Devon derives its name from Dumnonia (the shift from ''m'' to ''v'' is a typical Celtic consonant shift). During the Briti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faeces
Feces ( or faeces), known colloquially and in slang as poo and poop, are the solid or semi-solid remains of food that was not digested in the small intestine, and has been broken down by bacteria in the large intestine. Feces contain a relatively small amount of metabolic waste products such as bacterially altered bilirubin, and dead epithelial cells from the lining of the gut. Feces are discharged through the anus or cloaca during defecation. Feces can be used as fertilizer or soil conditioner in agriculture. They can also be burned as fuel or dried and used for construction. Some medicinal uses have been found. In the case of human feces, fecal transplants or fecal bacteriotherapy are in use. Urine and feces together are called excreta. Skatole is the principal compound responsible for the unpleasant smell of feces. Characteristics The distinctive odor of feces is due to skatole, and thiols (sulfur-containing compounds), as well as amines and carboxylic acids. Skatole ...

Eurasian Wren
The Eurasian wren (''Troglodytes troglodytes'') or northern wren is a very small insectivorous bird, and the only member of the wren family Troglodytidae found in Eurasia and Africa (Maghreb). In Anglophone Europe, it is commonly known simply as the wren. It has a very short tail which is often held erect, a short neck and a relative long thin bill. It is russet brown above, paler buff-brown below and has a cream buff supercilium. The sexes are alike. The species was once lumped with '' Troglodytes hiemalis'' of eastern North America and '' Troglodytes pacificus'' of western North America as the winter wren. The Eurasian wren occurs in Europe and across the Palearctic – including a belt of Asia from northern Iran and Afghanistan across to Japan. It is migratory in only the northern parts of its range. It is also highly polygynous, an unusual mating system for passerines. The scientific name is taken from the Greek word "troglodytes" (from τρώγλη "hole", and δ ...

Tree Pipit
The tree pipit (''Anthus trivialis'') is a small passerine bird which breeds across most of Europe and the Palearctic as far East as the East Siberian Mountains. It is a long-distance migrant moving in winter to Africa and southern Asia. The scientific name is from Latin: ''anthus'' is the name for a small bird of grasslands, and the specific '' trivialis'' means "common". Taxonomy The tree pipit was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Alauda trivialis''. Linnaeus noted that the species occurred in Sweden. The specific epithet ''trivialis'' is Latin meaning "common" or "ordinary" from Latin ''trivium'' meaning "public street". The tree pipit is now placed in the genus ''Anthus'' that was introduced in 1805 by the German naturalist Johann Matthäus Bechstein. Two subspecies are recognised: * ''A. t. trivialis'' (Linnaeus, 1758) – breeds across Europe to southwest Siberia, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Hobby
The Eurasian hobby (''Falco subbuteo'') or just hobby, is a small, slim falcon. It belongs to a rather close-knit group of similar falcons often considered a subgenus '' Hypotriorchis''. Taxonomy and systematics The first formal description of the Eurasian hobby was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the present binomial name ''Falco subbuteo''. The genus name ''falco'' derives from Late Latin ''falx'', ''falcis'', a sickle, referring to the wing profile of the bird. The species name ''subbuteo'' is from Latin ''sub'', "below, less than, under" and ''buteo'', "buzzard". The species' English name comes from Old French ''hobé'' or ''hobet''. It became the trademark for the Subbuteo games company after its creator, who was an ornithologist, was refused permission to register "Hobby". Currently two subspecies are recognized: * ''F. s. subbuteo'': the nominate race is resident in Africa, Europe and Central and East ...

European Nightjar
The European nightjar (''Caprimulgus europaeus''), common goatsucker, Eurasian nightjar or just nightjar, is a crepuscular and nocturnal bird in the nightjar family that breeds across most of Europe and the Palearctic to Mongolia and Northwestern China. The Latin generic name refers to the old myth that the nocturnal nightjar suckled from goats, causing them to cease to give milk. The six subspecies differ clinally, the birds becoming smaller and paler towards the east of the range. All populations are migratory, wintering in sub-Saharan Africa. Their densely patterned grey and brown plumage makes individuals difficult to see in the daytime when they rest on the ground or perch motionless along a branch, although the male shows white patches in the wings and tail as he flies at night. The preferred habitat is dry, open country with some trees and small bushes, such as heaths, forest clearings or newly planted woodland. The male European nightjar occupies a territory in sprin ...

European Stonechat
The European stonechat (''Saxicola rubicola'') is a small passerine bird that was formerly classed as a subspecies of the common stonechat. Long considered a member of the thrush family, Turdidae, genetic evidence has placed it and its relatives in the Old World flycatcher family, Muscicapidae. Taxonomy and systematics The European stonechat was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his ''Systema Naturae'' under the binomial name ''Motacilla rubicola''. This species is now placed in the genus ''Saxicola'' that was introduced by the German naturalist Johann Matthäus Bechstein in 1802. The English name derives from its call, sounding like two stones knocked together. The scientific name ''Saxicola'' means "rock-dweller", from Latin ''saxum'' meaning "a rock" and ''incola'' meaning "dwelling in". The specific epithet combines the Latin ''rubus'' meaning "brambles" with ''incola''. The subspecies name ''hibernans'' refers to ...

Dartford Warbler
The Dartford warbler (''Curruca undata'') is a typical warbler from the warmer parts of western Europe and northwestern Africa. It is a small warbler with a long thin tail and a thin pointed bill. The adult male has grey-brown upperparts and is dull reddish-brown below except for the centre of the belly which has a dirty white patch. It has light speckles on the throat and a red eye-ring. The sexes are similar but the adult female is usually less grey above and paler below. Its breeding range lies west of a line from southern England to the heel of Italy (southern Apulia). The Dartford warbler is usually resident all year in its breeding range, but there is some limited migration. Taxonomy and systematics The Dartford warbler was first described in 1776 by the Welsh naturalist, Thomas Pennant. He introduced the English name and based his description on two specimens that had been obtained by the ornithologist John Latham from Bexley Heath, near Dartford in Kent. In 1783 Latham i ...

Sand Lizard
The sand lizard (''Lacerta agilis'') is a lacertid lizard distributed across most of Europe from France and across the continent to Lake Baikal in Russia. It does not occur in European Turkey. Its distribution is often patchy. In the sand lizard's northern populations, such as in Great Britain, it is only able to survive along coastal heathlands where the sand is hot enough to incubate their eggs. Males are known for their bright colorations and aggressive behaviors when competing for females. Their mating process is unique because of its relatively short time period and because males are generally more selective with who they mate with than females. Females typically only lay a single clutch in a year. Sand lizards spend most of their time basking, foraging, or under vegetation and prefer to live in diverse habitats. Males have their own home territories that are very wide and often overlap with other males. These males compete with each other while females have smaller home te ...

Dorset
Dorset ( ; archaically: Dorsetshire , ) is a county in South West England on the English Channel coast. The ceremonial county comprises the unitary authority areas of Bournemouth, Christchurch and Poole and Dorset (unitary authority), Dorset. Covering an area of , Dorset borders Devon to the west, Somerset to the north-west, Wiltshire to the north-east, and Hampshire to the east. The county town is Dorchester, Dorset, Dorchester, in the south. After the Local Government Act 1972, reorganisation of local government in 1974, the county border was extended eastward to incorporate the Hampshire towns of Bournemouth and Christchurch. Around half of the population lives in the South East Dorset conurbation, while the rest of the county is largely rural with a low population density. The county has a long history of human settlement stretching back to the Neolithic era. The Roman conquest of Britain, Romans conquered Dorset's indigenous Durotriges, Celtic tribe, and during the Ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
