Taxonomy Articles Created By Polbot
280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a search engine taxonomy. Etymology The word was coined in 1813 by the Swiss botanist A ...

Mammals Of Central Asia
A mammal () is a vertebrate animal of the class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), constitutes the large ...

Mammals Of Russia
This is a list of the mammal species recorded in Russia. There are 266 mammal species in Russia, of which five are critically endangered, thirteen are endangered, twenty-six are vulnerable, and six are near threatened. One of the species listed for Russia is extinct and one can no longer be found in the wild. All the mammals of Russia are in the subclass Theria and infraclass Eutheria, being all Placentalia, placental. The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature: Order: Rodentia (rodents) Rodents make up the largest order of mammals, with over 40% of mammalian species. They have two incisors in the upper and lower jaw which grow continually and must be kept short by gnawing. Most rodents are small though the capybara can weigh up to . *Suborder: Hystricognathi **Family: Hystricidae (Old World porcupines) ***Genus: ''Hystrix (porcupine), Hystrix'' ****Indian crested porcupin ...

Allactaga
The genus ''Allactaga'' contains the five-toed jerboas of Asia. They are small mammals belonging to the order of rodents. They are characteristically known as the hopping rodents of the desert and semi-arid regions. They have long hind feet, short forelimbs, and walk upright. They have large ears in comparison to their body size and a large tail. The tail assists and serves as support when the jerboa is standing upright. The jerboa body length ranges from 5–15 cm and has a tail ranging from 7–25 cm."Jerboa (rodent)" ''Encyclopædia Britannica''. Encyclopædia Britannica Inc., 2013. Web. 12 October 2013.

Least Concern
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...

Dacha
A dacha (Belarusian, Ukrainian language, Ukrainian and rus, дача, p=ˈdatɕə, a=ru-dacha.ogg) is a seasonal or year-round second home, often located in the exurbs of former Soviet Union, post-Soviet countries, including Russia. A cottage (, ') or shack serving as a family's main or only home, or an outbuilding, is not considered a dacha, although some dachas recently have been converted to year-round residences and vice versa. The noun "dacha", coming from verb "davat" (''to give''), originally referred to land allotted by the tsar to his nobles; and indeed the dacha in Soviet times is similar to the Allotment (gardening), allotment in some Western countries – a piece of land allotted, normally free, to citizens by the local government for gardening or growing vegetables for personal consumption. With time the name for the land was applied to the building on it. In some cases, owners occupy their dachas for part of the year and rent them to urban residents as summer retrea ...

Gagea
''Gagea'' is a large genus of spring flowers in the lily family. It is found primarily in Eurasia with a few species extending into North Africa and one species ('' Gagea serotina'') in North America. The genus is named after the English naturalist Sir Thomas Gage (1781–1820). They were originally described as species of ''Ornithogalum'', which, together with the usual yellow colour of the flowers, explains the English name yellow star-of-Bethlehem for the common European species, '' Gagea lutea''. p. 25.

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and Mandible, lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/ricochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...
