Aveyron
Aveyron (; ) is a Departments of France, department in the Regions of France, region of Occitania (administrative region), Occitania, Southern France. It was named after the river Aveyron (river), Aveyron. Its inhabitants are known as ''Aveyronnais'' (masculine) or ''Aveyronnaises'' (feminine) in French. The inhabitants of Aveyron's Prefectures in France, prefecture, Rodez, are called ''Ruthénois'', based upon the first settlers in the area, the Ruteni.

The Larvæ Of The British Butterflies And Moths BHL41107833
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun '' the ...

Plebejus Argus
The silver-studded blue (''Plebejus argus'') is a butterfly in the family Lycaenidae. It has bright blue wings rimmed in black with white edges and silver spots on its hindwings, lending it the name of the silver-studded blue. ''P. argus'' can be found across Europe and east across the Palearctic, but it is most often studied in the United Kingdom where the species has experienced a severe decline in population due to habitat loss and fragmentation. ''P. argus'' engages in mutualism with ants that contribute to the butterflies' reproductive fitness by providing protection from predation and parasitism from the point of egg laying to their emergence as adults. ''P. argus'' adults emerge at the end of June and beginning of July and engage in flight until the beginning of August. The butterfly is adaptable to different habitats and is found in heathland, mossland, and limestone grassland. Tending towards a sedentary lifestyle and typically flying less than a day, ''P. argus'' mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horseshoe Vetch
''Hippocrepis comosa'', the horseshoe vetch, is a species of perennial flowering plant belonging to the genus '' Hippocrepis'' in the family Fabaceae. Description The overall appearance depends on its habitat: sometimes it forms upright clumps of flowers; at other times, it sends prostrate leafy runners over a wide area; sometimes it distributes itself as single flowers. The flowers are small, yellow or sometimes orange/red (becoming yellow as they mature), and of typical shape for the family Fabaceae: these appear for a period of two weeks around May.. Propagation The rate of seed production is variable: relatively low and sometimes negligible seed production. Seedlings remain the predominant method of extending its range. It has a low germination rate in the wild, although this can be improved in nurseries. Distribution ''Hippocrepis comosa'' is found in the UK, predominantly in the south.. Habitat ''Hippocrepis comosa'' is a calciole (found only on chalk and lime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotswolds
The Cotswolds ( ) is a region of central South West England, along a range of rolling hills that rise from the meadows of the upper River Thames to an escarpment above the Severn Valley and the Vale of Evesham. The area is defined by the bedrock of Jurassic limestone that creates a type of grassland habitat that is quarry, quarried for the golden-coloured Cotswold stone. It lies across the boundaries of several English counties: mainly Gloucestershire and Oxfordshire, and parts of Wiltshire, Somerset, Worcestershire, and Warwickshire. The highest point is Cleeve Hill, Gloucestershire, Cleeve Hill at , just east of Cheltenham. The predominantly rural landscape contains stone-built villages, towns, stately homes and gardens featuring the local stone. A large area within the Cotswolds has been designated as a Area of Outstanding Natural Beauty, National Landscape (formerly known as Area of Outstanding Natural Beauty, or AONB) since 1966. The designation covers , with boundaries rou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat (ecology)
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior of a stem, a rotten log, ...

Calcareous Soil
Calcareous () is an adjective meaning "mostly or partly composed of calcium carbonate", in other words, containing lime or being chalky. The term is used in a wide variety of scientific disciplines. In zoology ''Calcareous'' is used as an adjectival term applied to anatomical structures which are made primarily of calcium carbonate, in animals such as gastropods, i.e., snails, specifically in relation to such structures as the operculum, the clausilium, and the love dart. The term also applies to the calcium carbonate tests of, often, more-or-less microscopic Foraminifera. Not all tests are calcareous; diatoms and radiolaria have siliceous tests. The molluscs are calcareous organisms, as are the calcareous sponges ( Calcarea), that have spicules which are made of calcium carbonate. Additionally, reef-building corals, or Scleractinia, are calcareous organisms that form their rigid skeletal structure through the precipitation of aragonite (''i.e.'', a polymorph of calc ...

Martin Down
Martin and Tidpit Downs is a biological Site of Special Scientific Interest north-west of Fordingbridge in Hampshire. Martin Down is a national nature reserve and an area of is a ''Nature Conservation Review'' site, Grade I. Bokerley Dyke, a prehistoric linear earthwork and scheduled monument, runs through the site. This site is rich in prehistoric earthworks, including Bokerley Dyke. It has chalk grassland, heath and scrub, with a rich herb flora. Sheep grazing is increasing the botanical quality of the grassland. There is an outstanding assemblage of butterflies, with 36 species recorded, including marbled white, dark green fritillary, silver-spotted skipper and Duke of Burgundy Duke of Burgundy () was a title used by the rulers of the Duchy of Burgundy, from its establishment in 843 to its annexation by the Crown lands of France, French crown in 1477, and later by members of the House of Habsburg, including Holy Roman E ....

Calcareous Grassland
Calcareous grassland (or alkaline grassland) is an ecosystem associated with thin basic soil, such as that on chalk and limestone downland. 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). Biodiversity 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. The lichen flora of chalk grasslands represents ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Der Naturforscher
''Der Naturforscher'' ( "The Naturalist") was a German scientific publication of the Enlightenment devoted to natural history. It was published yearly from 1774 to 1804, by J. J. Gebauers Witwe and Joh. Jac. Gebauer at Halle and edited first by Johann Ernst Immanuel Walch (from 1774 to 1778) and later by Johann Christian Daniel von Schreber (from 1779 to 1802). Both editors were also contributors. Most of the articles concern aspects of invertebrate zoology, mostly entomology and conchology. A few concern ornithology and other subjects, including mineralogy. It is usually bound in fifteen volumes octavo. Indices and registers are given at ten year intervals enumerating 640 memoirs. Just over 150 plates accompany the text. Many of the illustrations are by Johann Stephan Capieux and are of a very high standard. Armin Geus provides comprehensive indices.
