Eduard Friedrich Eversmann
Alexander Eduard Friedrich Eversmann (23 January 1794 – 14 April 1860) was a Prussian biologist and explorer. Early life and education Eversmann was born in Westphalia on 23 January 1794 and studied at the universities of Marburg, Halle, Berlin and Dorpat. He received his degree of Philosophy and Master of Liberal Sciences at Halle in 1814, and at Dorpat graduated as a Doctor of Medicine and Surgery in 1817. During the next three years he travelled in the southern Urals, collecting specimens and sending them to Hinrich Lichtenstein at the university of Berlin. Career Eversmann had long planned to travel into Central Asia to collect natural history specimens. He had studied the languages, customs and Muslim religion of the peoples of the area. In 1820 he set off for Bukhara disguised as a merchant, a journey he described in ''Reise Orenburg nach Buchara'' (1823), with a natural history appendix by Lichtenstein. In 1825 he travelled with a military expedition to Khiva. In 182 ...

Westphalia
Westphalia (; ; ) is a region of northwestern Germany and one of the three historic parts of the state of North Rhine-Westphalia. It has an area of and 7.9 million inhabitants. The territory of the region is almost identical with the historic Province of Westphalia, which was a part of the Kingdom of Prussia from 1815 to 1918 and the Free State of Prussia from 1918 to 1946. In 1946, Westphalia merged with North Rhine, another former part of Prussia, to form the newly created state of North Rhine-Westphalia. In 1947, the state with its two historic parts was joined by a third one: Lippe, a former Principality of Lippe, principality and Free State of Lippe, free state. The seventeen Districts of Germany, districts and nine Independent city#Germany, independent cities of Westphalia and Lippe (district), the single district of Lippe are members of the North Rhine-Westphalia#Subdivisions, Westphalia-Lippe Regional Association (''Landschaftsverband Westfalen-Lippe'').

Zoology
Zoology ( , ) is the scientific study of animals. Its studies include the anatomy, structure, embryology, Biological classification, classification, Ethology, habits, and distribution of all animals, both living and extinction, extinct, and how they interact with their ecosystems. Zoology is one of the primary branches of biology. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and used this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. Modern zoology has its origins during the Renaissance and early modern period, with Carl Linnaeus, Antonie van Leeuwenhoek, Robert Hooke, Charles Darwin, Gregor Mendel a ...

Crossobamon Eversmanni
''Crossobamon eversmanni'', also known commonly as the comb-toed gecko, is a species of Asian gecko, a lizard in the family Gekkonidae. Etymology The specific name, ''eversmanni'', is in honor of Russian-German entomologist Alexander Eduard Friedrich Eversmann. Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Crossobamon eversmanni'', p. 86). Geographic range ''C. eversmanni'' is found in Iran, Pakistan, and several other countries of Central Asia. Habitat The preferred natural habitat of ''C. eversmanni'' is sandy areas of desert, grassland, and shrubland, at altitudes of . Behavior ''C. eversmanni'' is terrestrial, nocturnal, and lives in burrows. Reproduction ''C. eversmanni'' is oviparous. A sexually mature female may lay 2–3 clutches per year, with 1–2 eggs in each clutch. Subspecies Two subspecies are recognized as being valid, including the nominotypical ...

Darevskia
''Darevskia'' is a genus of wall lizards of the family (biology), family Lacertidae. Member species are native to the Caucasus, Iran and Turkey, living in forest and grassy habitats with numerous rock outcrops. Among rock lizards, seven parthenogenetic species are known. Description ''Darevskia'' species are small lizards with a head and body length of , and with a tail length about two times longer. The body is usually flattened, the head is pointed in shape and in most species flattened in a vertical plane, which allows lizards to hide in narrow crevices between stones and rocks. Rock lizards have relatively long legs with special calluses on the inner surfaces of the paws and sharp claws, thanks to which they quickly move along the vertical rough surfaces of rocks and stones. The color of rock lizards varies from different tones of green to sand. Females are usually colored paler than males. On the dorsal side of the body, rock lizards have an occipital stripe composed of a se ...

Lizard
Lizard is the common name used for all Squamata, squamate reptiles other than snakes (and to a lesser extent amphisbaenians), encompassing over 7,000 species, ranging across all continents except Antarctica, as well as most Island#Oceanic islands, oceanic Archipelago, island chains. The grouping is Paraphyly, paraphyletic as some lizards are more closely related to snakes than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards") have secondarily lost their legs, and have long snake-like bodies. Some lizards, such as the forest-dwelling ''Draco (genus), Draco'', are able to glide. They are often Territory (animal), territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often b ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ...

Herpetology
Herpetology (from Ancient Greek ἑρπετόν ''herpetón'', meaning "reptile" or "creeping animal") is a branch of zoology concerned with the study of amphibians (including frogs, salamanders, and caecilians (Gymnophiona)) and reptiles (including snakes, lizards, turtles, crocodilians, and tuataras). Birds, which are cladistically included within Reptilia, are traditionally excluded here; the separate scientific study of birds is the subject of ornithology. The precise definition of herpetology is the study of ectothermic (cold-blooded) tetrapods. This definition of "herps" (otherwise called "herptiles" or "herpetofauna") excludes fish; however, it is not uncommon for herpetological and ichthyological scientific societies to collaborate. For instance, groups such as the American Society of Ichthyologists and Herpetologists have co-published journals and hosted conferences to foster the exchange of ideas between the fields. Herpetological societies are formed to ...

Eversmann's Rustic
''Actebia fennica'', the black army cutworm or Eversmann's rustic, is a moth of the family Noctuidae. The species was first described by August Michael Tauscher in 1806. It has a Holarctic distribution from Newfoundland through western Europe, Siberia, the Far East, Mongolia, northern China to Korea and Japan. In North America it is mainly found in the boreal region, south to New England, southern Montana and northern Oregon. The wingspan is 39-42 mm and the typical length is ~23 mm. Adults are on wing from July to September depending on the location. There is one generation per year.

Eversmann's Parnassian
''Parnassius eversmanni'', or Eversmann's parnassian, is a high-altitude butterfly which is found in eastern Russia, Mongolia, Japan, Alaska, and the Yukon. It is a member of the snow Apollo genus (''Parnassius'') of the swallowtail family, Papilionidae. The species was named to honour Eduard Friedrich Eversmann. Description Note: The wing pattern in ''Parnassius'' species is inconsistent and the very many subspecies and forms make identification problematic and uncertain. Structural characters derived from the genitalia, wing venation, sphragis and foretibial epiphysis are more, but not entirely reliable. The description given here is a guide only. For an identification key see Ackery P.R. (1975). Ground-colour yellow in male yellow or yellowish white in female. Resembles in pattern very closely the female of '' Parnassius felderi'': forewing grey at base and costal margin, and greyish glossy at distal margin; beyond the cell a curved discal band shaded with grey and a similar ...

Eversmann's Redstart
Eversmann's redstart (''Phoenicurus erythronotus''), also known as the rufous-backed redstart, is a passerine bird belonging to the genus ''Phoenicurus''. It was formerly classified in the thrush family Turdidae but is now placed in the Old World flycatcher family Muscicapidae. It was described by the German biologist Eduard Friedrich Eversmann who is commemorated in the bird's English name. Description It is one of the larger redstarts, long with a wingspan of and weigh . The bill and legs are black. The male in breeding plumage has a black mask and grey crown and nape. The back and rump are rufous and the tail is also rufous apart from the darker central feathers. The wings are dark with white patches on the scapulars and primary-coverts. The underparts are mainly rufous with white on the belly and undertail-coverts. Non-breeding and first-winter males are similar but much duller and browner. Females are mostly grey-brown. They have a rufous tail with a dark centre, a pale ...
