Eugenius Johann Christoph Esper
Eugenius Johann Christoph Esper (2 June 1742 – 27 July 1810) was a German zoologist and naturalist. Born in Wunsiedel in Bavaria, he was professor of zoology at Erlangen university. Life and work Eugen and his brother Friedrich were introduced to natural history at an early age by their father Friedrich Lorenz Esper, an amateur botanist. Encouraged to abandon his theology course by his professor of botany Casimir Christoph Schmidel (1718–1792) Eugen Esper, instead, took instruction in natural history. He obtained his doctorate of philosophy at the university of Erlangen in 1781 with a thesis entitled ''De varietatibus specierum in naturale productis''. The following year, he started to teach at the university initially as extraordinary professor, a poorly paid position, then in 1797 as the professor of philosophy. He directed the department of natural history in Erlangen from 1805. Thanks to him the university collections of minerals, birds, plants, shells and insects ...

Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the H ...

Zygaena
''Zygaena'' is a genus of moths in the family Zygaenidae. These brightly coloured, day-flying moths are native to the West Palearctic. Description Adalbert Seitz described them thus: "Small, stout, black insects, sometimes with metallic gloss. Antenna very strongly developed; the club being considerably incrassate distally. Tongue long and strong. Legs rather short. Forewing elongate oval,black or red, rarely spotted with white or yellow. Hindwing small, usually red, seldom black. —Larva strongly humpbacked, very soft, downy-haired. Pupa in a paper-like silky cocoon, the sheaths of legs and wings being loosely soldered together. The moths are mostly local, their stations being often restricted to a mountain, a meadow, etc. They appear mostly in large numbers at their special localities, swarming about flowers, which they suck, fore instance Scabious, Thistles, Eryngium, etc., their flight being slow and straight on. The body of these insects contains, as in the other Zygaenids ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lotus Corniculatus
''Lotus corniculatus'' is a flowering plant in the pea family Fabaceae, native to grasslands in temperate Eurasia and North Africa. Common names include common bird's-foot trefoil, eggs and bacon, birdsfoot deervetch, and just bird's-foot trefoil, though the latter name is often also applied to other members of the genus. It is a Perennial plant, perennial herbaceous plant, similar in appearance to some clovers. The name 'bird's foot' refers to the appearance of the seed pods on their stalk. Five leaflets are present, but with the central three held conspicuously above the others, hence the use of the name 'trefoil'. It is often used as forage and is widely used as food for livestock due to its nonbloating properties. Description The height of the plant is variable, from , occasionally more where supported by other plants; the stems can reach up to long. It is typically sprawling at the height of the surrounding grassland. It can survive fairly close grazing, trampling, and mow ...

Coronilla Varia
''Securigera varia'' (synonym ''Coronilla varia''), commonly known as crownvetch or purple crown vetch, is a low-growing legume vine. It is native to Africa, Asia and Europe and is commonly used throughout the United States and Canada for erosion control, roadside planting and soil rehabilitation. It has become an invasive species in many states of the US. Crownvetch grows 1 to 2 feet tall and bears small clusters of 1/2-inch pink and white flowers from early summer to late fall. The variety Penngift produces mounds of pink flowers. Crownvetch is a tough, aggressive spreading plant that will crowd out its neighbors in a show garden but is well suited to a sunny bank, where it will grow for decades with little to no fertilizing, mowing, or weeding since the thick foliage prevents weeds from growing amid it.

Hippocrepis Comosa
''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] |
Cyanide
Cyanide is a naturally occurring, rapidly acting, toxic chemical that can exist in many different forms. In chemistry, a cyanide () is a chemical compound that contains a functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. In inorganic cyanides, the cyanide group is present as the anion . Soluble salts such as sodium cyanide (NaCN) and potassium cyanide (KCN) are highly toxic. Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially. It is obtained by acidification of cyanide salts. Organic cyanides are usually called nitriles. In nitriles, the group is linked by a covalent bond to carbon. For example, in acetonitrile (), the cyanide group is bonded to methyl (). Although nitriles generally do not release cyanide ions, the cyanohydrins do and are thus rather toxic. Bonding The cyanide ion is isoelectronic with carbon monoxide a ...

Aposematism
Aposematism is the advertising by an animal to potential predators that it is not worth attacking or eating. This unprofitability may consist of any defences which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These advertising signals may take the form of conspicuous coloration, sounds, odours, or other perceivable characteristics. Aposematic signals are beneficial for both predator and prey, since both avoid potential harm. The term was coined in 1877 by Edward Bagnall Poulton for Alfred Russel Wallace's concept of warning coloration. Aposematism is exploited in Müllerian mimicry, where species with strong defences evolve to resemble one another. By mimicking similarly coloured species, the warning signal to predators is shared, causing them to learn more quickly at less of a cost. A genuine aposematic signal that a species actually possesses chemical or physical defences is not the only way to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Jordan (zoologist, Born 1861)
Heinrich Ernst Karl Jordan (7 December 1861 – 12 January 1959) was a German-British entomologist. He took a special interest in the taxonomy and classification of butterflies, beetles and fleas. Jordan was a founder of the International Congress of Entomology. Jordan was born in a farming family in Almstedt, raised by an uncle after the death of his father in 1855, finished school in Hildesheim and educated at Göttingen University. After a year of military service, he taught at Münden Grammar School for five years and came in contact with zoologist August Metzger and Count Berlepsch that led to a growth in his natural history interest. Through their recommendation he received an invitation to joined Ernst Hartert at Rotschild's museum. In 1893 he began work at Walter Rothschild's Natural History Museum at Tring, specialising in Coleoptera, Lepidoptera and Siphonaptera. Jordan published over 400 papers, many jointly with Charles and Walter Rothschild. He described 2,575 ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically extent, is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is distance between the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stood at and owned one of the largest wingspans at . Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, independently of wing shape or sweep. Implications for aircraft design and anima ...
