A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it f ...

Gravel Extraction
A gravel pit is an open-pit mine for the extraction of gravel. Gravel pits often lie in river valleys where the water table is high, so they may naturally fill with water to form ponds or lakes. Old, abandoned gravel pits are normally used either as nature reserves, or as amenity areas for water sports, landfills and walking. In Germany former gravel or sand pits that have filled up with water are known as ''Baggersee'' ("power dug lake") and popular for recreational use. In addition, many gravel pits in the United Kingdom have been stocked with freshwater fish such as the common carp to create coarse fishing locations. Gravel and sand are mined for concrete, construction aggregate and other industrial mineral uses.

Grass Snake
The grass snake (''Natrix natrix''), sometimes called the ringed snake or water snake, is a Eurasian non-venomous colubrid snake. It is often found near water and feeds almost exclusively on amphibians. Subspecies Many subspecies are recognized, including: ''Natrix natrix helvetica'' ( Lacépède, 1789) was formerly treated as a subspecies, but following genetic analysis it was recognised in August 2017 as a separate species, ''Natrix helvetica'', the barred grass snake. Four other subspecies were transferred from ''N. natrix'' to ''N. helvetica'', becoming ''N. helvetica cettii'', ''N. helvetica corsa'', ''N. helvetica lanzai'' and ''N. helvetica sicula''. Description The grass snake is typically dark green or brown in colour with a characteristic yellow or whitish collar behind the head, which explains the alternative name ringed snake. The colour may also range from grey to black, with darker colours being more prevalent in colder regions, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linnet
The common linnet (''Linaria cannabina'') is a small passerine bird of the finch family, Fringillidae. It derives its common name and the scientific name, ''Linaria'', from its fondness for hemp seeds and flax seeds—flax being the English name of the plant from which linen is made. Taxonomy In 1758, the Swedish naturalist Carl Linnaeus included the common linnet in the 10th edition of his ''Systema Naturae'' under the binomial name, ''Acanthis cannabina''. The species was formerly placed in the genus ''Carduelis'' but based on the results of a phylogenetic analysis of mitochondrial and nuclear DNA sequences published in 2012, it was moved to the genus ''Linaria'' that had been introduced by the German naturalist Johann Matthäus Bechstein in 1802. The genus name ''linaria'' is the Latin for a linen-weaver, from ''linum'', "flax". The species name ''cannabina'' comes from the Latin for hemp. The English name has a similar root, being derived from Old French ''linette'', fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meadow Pipit
The meadow pipit (''Anthus pratensis'') is a small passerine bird, which breeds in much of the Palearctic, from southeastern Greenland and Iceland east to just east of the Ural Mountains in Russia, and south to central France and Romania; an isolated population also occurs in the Caucasus Mountains. It is migratory over most of its range, wintering in southern Europe, North Africa, and south-western Asia, but is resident year-round in western Europe, though even here many birds move to the coast or lowlands in winter. Taxonomy The meadow pipit was formally described by Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of his ''Systema Naturae'' under the binomial name ''Alauda pratensis''. The type locality is Sweden. The meadow pipit is now the type species of the genus ''Anthus'' that was introduced in 1805 by German naturalist Johann Matthäus Bechstein. The species is monotypic; no subspecies are recognised. The generic name ''Anthus'' is the Latin name for a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skylark
''Alauda'' is a genus of larks found across much of Europe, Asia and in the mountains of north Africa, and one of the species (the Raso lark) endemic to the islet of Raso in the Cape Verde Islands. Further, at least two additional species are known from the fossil record. The current genus name is from Latin ''alauda'', "lark". Pliny the Elder thought the word was originally of Celtic origin. Taxonomy and systematics The genus ''Alauda'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. The type species was subsequently designated as the Eurasian skylark. The genus ''Alauda'' has four extant and at least two extinct species. Formerly, many other species have also been considered to belong to the genus. Extant species The genus contains four species: Extinct species * †''Alauda xerarvensis'' (late Pliocene of Varshets, Bulgaria) * †''Alauda tivadari'' (late Miocene of Polgardi, Hungary) Former species Previ ...

Reed Bunting
The common reed bunting (''Emberiza schoeniclus'') is a passerine bird in the bunting family Emberizidae, a group now separated by most modern authors from the finches, Fringillidae. The genus name ''Emberiza'' is from Old German ''Embritz'', a bunting. The specific ''schoeniclus'' is from Ancient Greek ''skhoiniklos'', a now unknown waterside bird. It breeds across Europe and much of the Palearctic. Most birds migrate south in winter, but those in the milder south and west of the range are resident. It is common in reedbeds and also breeds in drier open areas such as moorland and cultivation. For example, it is a component of the purple moor grass and rush pastures, a type of Biodiversity Action Plan habitat in the UK. It occurs on poorly drained neutral and acidic soils of the lowlands and upland fringe. Taxonomy The common reed bunting was described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name '' ...

Ophrys Apifera
''Ophrys apifera'', known in Europe as the bee orchid, is a perennial herbaceous plant of the family Orchidaceae. It serves as an example of sexually deceptive pollination and floral mimicry, as well as of a highly selective and highly evolved plant–pollinator relationship. Description ''Ophrys apifera'' grows to a height of . This hardy orchid develops small rosettes of leaves in autumn that continue to grow slowly during winter. Basal leaves are ovate or oblong-lanceolate, and upper leaves and bracts are ovate-lanceolate and sheathing. Leaves exhibit parallel venation. The plant blooms from mid-April in continental Europe, but in the United Kingdom it flowers June to July. A flower spike is produced, composed from one to twelve flowers. Three large, purple sepals surround the base of the flower, which can easily be mistaken for petals. The true petals lie just above the sepals as two short, pubescent green structures protruding laterally from a central column. A third, ...

Pyramidal Orchid
''Anacamptis pyramidalis'', the pyramidal orchid, is a perennial herbaceous plant belonging to the genus ''Anacamptis'' of the family Orchidaceae. The scientific name ''Anacamptis'' derives from Greek ανακάμτειν 'anakamptein' meaning 'bend forward', while the Latin name ''pyramidalis'' refers to the pyramidal form of the inflorescence. Description This hardy plant reaches on average of height, with a maximum of . The stem is erect and unbranched. The basal leaves are linear-lanceolate with parallel venation, up to long, the cauline ones are shorter and barely visible on the stem. The arrangement of hermaphroditic flowers in a compact pyramidal shape is very distinctive and gives the orchid its common name. The colour of the flower varies from pink to purple, or rarely white, and the scent is described as "foxy". The flowers have six tepals, being three small sepals and three petals. Two small petals are on the sides, while the third and lower ( labellum) is large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chalk Grassland
Calcareous grassland (or alkaline grassland) is an ecosystem associated with thin basic soil, such as that on chalk and limestone downland. Plants on calcareous grassland are typically short and hardy, and include grasses and herbs such as clover. Calcareous grassland is an important habitat for insects, particularly butterflies and ants, and is kept at a plagioclimax by grazing animals, usually sheep and sometimes cattle. Rabbits used to play a part but due to the onset of myxomatosis their numbers decreased so dramatically that they no longer have much of a grazing effect. There are large areas of calcareous grassland in northwestern Europe, particularly areas of southern England, such as Salisbury Plain and the North and South Downs. The machair forms a different kind of calcareous grassland, where fertile low-lying plains are formed on ground that is calcium-rich due to shell sand (pulverised sea shells).

Grassland
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessment of Global Ecosystems, 2000) * "A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
