Colias Chrysotheme
''Colias chrysotheme'', the lesser clouded yellow, is a small Palearctic butterfly belonging to the family Pieridae. Description The female is white, with a tinge of yellow green. The male is pale yellow on the upper wing, and the edges are black or dark gray with a reddish fringe. ''Colias chrysotheme'' is the smallest of the three orange yellowing species found in Central Europe and has a wing span of 36 to 44 millimeters, with the second generation imagines often being slightly larger than the first generation. The wing upper side of the males is orange-yellow coloured and has a dark outer marginal band, which is narrower on the hindwing. The orange colour is slightly weaker than that of ''Colias croceus'' and much weaker than in ''Colias myrmidone''. The yellow veins in the dark outer marginal band are in ''chrysotheme'' recognizable on the anterior and posterior wings, whereas in ''croceus'' these are usually present only on the forewings tips and yellow veins are completely ...

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 ...

Astragalus
''Astragalus'' is a large genus of over 3,000 species of herbs and small shrubs, belonging to the legume family Fabaceae and the subfamily Faboideae. It is the largest genus of plants in terms of described species. The genus is native to temperate regions of the Northern Hemisphere. Common names include milkvetch (most species), locoweed (in North America, some species) and goat's-thorn ( ''A. gummifer'', ''A. tragacantha''). Some pale-flowered vetches (''Vicia'' spp.) are similar in appearance, but they are more vine-like than ''Astragalus''. Description Most species in the genus have pinnately compound leaves. There are annual and perennial species. The flowers are formed in clusters in a raceme, each flower typical of the legume family, with three types of petals: banner, wings, and keel. The calyx is tubular or bell-shaped. Ecology ''Astragalus'' species are used as food plants by the larvae of some Lepidoptera species including many case-bearing moths of the genus ''Col ...

Colias
''Colias'' is a genus of butterflies in the family Pieridae. They are often called clouded yellows; the North American name "sulphurs" is elsewhere used for Coliadinae in general. The closest living relative is the genus ''Zerene'', which is sometimes included in ''Colias''. This genus occurs throughout the Holarctic, including the arctic regions. They are also found in South America, Africa, China and India. Their caterpillars feed on certain Fabaceae, for example vetches (''Vicia''). While most are thus beneficial by keeping weeds at bay, some occasionally become nuisance pests on crops like alfalfa. In some species, the wings of males have brilliant ultraviolet reflection, while those of females do not. Adults of both sexes have various colour forms. Most if not all species of this genus, as usual for Coliadinae, do not sequester toxins or other noxious compounds from their food plants. They are therefore a well-loved prey item of insectivores as compared to ''Pieris'' of ...

Greek Mythology
A major branch of classical mythology, Greek mythology is the body of myths originally told by the Ancient Greece, ancient Greeks, and a genre of Ancient Greek folklore. These stories concern the Cosmogony, origin and Cosmology#Metaphysical cosmology, nature of the world, the lives and activities of List of Greek mythological figures, deities, Greek hero cult, heroes, and List of Greek mythological creatures, mythological creatures, and the origins and significance of the ancient Greeks' own cult (religious practice), cult and ritual practices. Modern scholars study the myths to shed light on the religious and political institutions of ancient Greece, and to better understand the nature of myth-making itself. The Greek myths were initially propagated in an oral tradition, oral-poetic tradition most likely by Minoan civilization, Minoan and Mycenaean Greece, Mycenaean singers starting in the 18th century BC; eventually the myths of the heroes of the Trojan War and its after ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ...

Classical Tradition
The Western classical tradition is the reception of classical Greco-Roman antiquity by later cultures, especially the post-classical West, involving texts, imagery, objects, ideas, institutions, monuments, architecture, cultural artifacts, rituals, practices, and sayings. Philosophy, political thought, and mythology are three major examples of how classical culture survives and continues to have influence. The West is one of a number of world cultures regarded as having a classical tradition, including the Indian, Chinese, and Islamic traditions. The study of the classical tradition differs from classical philology, which seeks to recover "the meanings that ancient texts had in their original contexts." It examines both later efforts to uncover the realities of the Greco-Roman world and "creative misunderstandings" that reinterpret ancient values, ideas and aesthetic models for contemporary use. The classicist and translator Charles Martindale has defined the reception of cla ...

Salix
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live, ...

Palearctic
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/ Afrotropic, Indian/ Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred Wall ...

Lake Neusiedl
Lake Neusiedl (german: Neusiedler See), or Fertő ( hu, Fertő (tó); hr, Nežidersko jezero, Niuzaljsko jezero; sl, Nežidersko jezero; sk, Neziderské jazero; cs, Neziderské jezero) is the largest endorheic lake in Central Europe, straddling the Austrian– Hungarian border. The lake covers , of which is on the Austrian side and on the Hungarian side. The lake's drainage basin has an area of about . From north to south, the lake is about long, and it is between and wide from east to west. On average, the lake's surface is above the Adriatic Sea and the lake is no more than deep. Water level fluctuations In the past, rainfall and aridity caused significant floods (which in 1768 enlarged the lake to its maximum documented size of ) and significant decreases in the lake's level, although frequently there seemed to be no apparent connection with the weather situation. Stratigraphy shows that the lake bed has totally dried up at least 100 times since its formation (18 ...
