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 podsols. There are no deep-burrowing earthworms so soil profile boundaries are sharp. There is often a thick litter layer on top of slow-decaying leaf litter. The habitat is susceptibl ...

Nitrogen Fixation
Nitrogen fixation is a chemical process by which molecular dinitrogen () is converted into ammonia (). It occurs both biologically and abiological nitrogen fixation, abiologically in chemical industry, chemical industries. Biological nitrogen fixation or ''diazotrophy'' is catalyzed by enzymes called nitrogenases. These enzyme complexes are encoded by the Nif gene, ''Nif'' genes (or ''Nif'' homologs) and contain iron, often with a second metal (usually molybdenum, but sometimes vanadium). Some nitrogen-fixing bacteria have symbiotic relationships with plants, especially legumes, mosses and aquatic ferns such as ''Azolla''. Looser non-symbiotic relationships between diazotrophs and plants are often referred to as associative, as seen in nitrogen fixation on rice roots. Nitrogen fixation occurs between some termites and fungus, fungi. It occurs naturally in the air by means of NOx, NOx production by lightning. Fixed nitrogen is essential to life on Earth.

Faeces
Feces (also known as faeces American and British English spelling differences#ae and oe, or fæces; : faex) 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 dry animal dung fuel, fuel or dried and used for wattle and daub, 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 excretion, excreta. Characteristics The distinctive odor of feces is due to skatole, and thiols (sulfur-containing compounds), as well as amines and carboxylic acids. Sk ...

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 relatively 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 Lumpers and splitters, lumped with ''winter wren, Troglodytes hiemalis'' of eastern North America and ''Pacific wren, 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 bird migration, migratory in only the northern parts of its range. It is also highly Polygyny in animals, polygynous, an unusual mating system for passerines. The scientific nam ...

Tree Pipit
The tree pipit (''Anthus trivialis'') is a small passerine bird that breeds throughout most of Europe and the Palearctic as far east as the East Siberian Mountains. It is a long-distance migrant, migrating in winter to Africa and southern Asia. The scientific name is from Latin: ''anthus'' is the name of a small bird of grasslands, and the specific '' trivialis'' means "common". The breeding habitat is open woodland and scrub. The nest is placed on the ground and usually 4–6 eggs are laid. This species is insectivorous like its relatives, but will also eat seeds. 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'' th ... [...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 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". Two subspecies are recognized: * ''F. s. subbuteo'': the nominate race is resident in Africa, Europe and Central and East Asia, winters in Central an ...

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. It is found across Europe, as far east as Ukraine and the South Caucasus, and in parts of North Africa. 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 comb ...

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 bird migration, 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 (ornithologist), John Latham from Bexley He ...
