Desert Dormouse
The desert dormouse (''Selevinia betpakdalaensis'') is a species of rodent in the dormouse family (biology), family, Gliridae. This species was formerly placed in its own family, Seleviniidae, but it is now considered to be a dormouse, Monotypic taxon, monotypic within the genus ''Selevinia''. It is Endemism, endemic to Kazakhstan. Taxonomy The desert dormouse was Species description, first described in 1939 by Belosludov & Bazhanov as ''Selevinia betpakdalaensis'', the specific name being derived from the Betpak-Dala , Betpak-Dala Desert, west of Lake Balkhash in Kazakhstan, where the Type (biology), type specimen was found. They included it in the rat and mouse Family (biology), family Muridae but later proposed placing it in a new family allied to Myoxidae (some taxonomists call this family Gliridae), the dormice. By 1947, they had concluded that it should be placed in Leithiinae, a subfamily of Myoxidae, along with three other dormouse genera. Description This dormouse has a ...

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, 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/richochetal (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 mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Endemic Fauna Of Kazakhstan
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are Indigenous (ecology), indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus, Cytisus aeolicus'' is an endemite of the Italian flora. ''Enidae, Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a Invasive species, non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a specie ...

EDGE Species
Evolutionarily Distinct and Globally Endangered (EDGE) species are animal species which have a high 'EDGE score', a metric combining endangered conservation status with the genetic distinctiveness of the particular taxon. Distinctive species have few closely related species, and EDGE species are often the only surviving member of their genus or even higher taxonomic rank. The extinction of such species would therefore represent a disproportionate loss of unique evolutionary history and biodiversity. Some EDGE species, such as elephants and pandas, are well-known and already receive considerable conservation attention, but many others, such as the vaquita (the world's rarest cetacean) the bumblebee bat (arguably the world's smallest mammal) and the egg-laying long-beaked echidnas, are highly threatened yet remain poorly understood, and are frequently overlooked by existing conservation frameworks. The Zoological Society of London launched the EDGE of Existence Programme in 2007 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dormice
A dormouse is a rodent of the family Gliridae (this family is also variously called Myoxidae or Muscardinidae by different taxonomists). Dormice are nocturnal animals found in Africa, Asia, and Europe. They are named for their long, dormant hibernation period of six months or longer. As only one species of dormouse – the hazel dormouse – is native to the United Kingdom, in everyday English usage "dormouse" can refer either to that one species or to the family as a whole. The English name of the species derived from the French ''dormeuse'', and the latter in turn possibly from the Languedocien ''radourmeire''. Etymology Concerning the dormouse's name, etymonline says "long-tailed Old World rodent noted for its state of semi-hibernation in winter, early 15c., possibly from Anglo-French ''dormouse'' 'tending to be dormant' (from stem of ''dormir'' 'to sleep,' see ''dormant''), with the second element mistaken for ''mouse''; or perhaps it is from a Middle English dialectal co ...

Mammals Described In 1939
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together wi ...

Data Deficient
A data deficient (DD) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as offering insufficient information for a proper assessment of conservation status to be made. This does not necessarily indicate that the species has not been extensively studied; but it does indicate that little or no information is available on the abundance and distribution of the species. The IUCN recommends that care be taken to avoid classing species as "data deficient" when the absence of records may indicate dangerously low abundance: "If the range of a taxon is suspected to be relatively circumscribed, if a considerable period of time has elapsed since the last record of the taxon, threatened status may well be justified""The Categories," in IUCN (1983).

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. 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 partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hibernation
Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months. Although traditionally reserved for "deep" hibernators such as rodents, the term has been redefined to include animals such as bears and is now applied based on active metabolic suppression rather than any absolute decline in body temperature. Many experts believe that the processes of daily torpor and hibernation form a continuum and utilise similar mechanisms. The equivalent during the summer months is aestivation. Hibernation functions to conserve energy when sufficient food is not available. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. Hibernation may last days, weeks, or months—depending on the species, ambient temperature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salsola Laricifolia
''Salsola'' is a genus of the subfamily Salsoloideae in the family Amaranthaceae. The genus ''sensu stricto'' is distributed in central and southwestern Asia, North Africa, and the Mediterranean. A common name of various members of this genus and related genera is saltwort, for their salt tolerance. The genus name ''Salsola'' is from the Latin ''salsus'', meaning "salty". Description The species of ''Salsola'' are mostly subshrubs, shrubs, small trees, and rarely annuals. The leaves are mostly alternate, rarely opposite, simple, and entire. The bisexual flowers have five tepals and five stamens. The pistil ends in two stigmata. The fruit is spherical with a spiral embryo and no perisperm. Systematics The genus name ''Salsola'' was first published in 1753 by Linnaeus in ''Species Plantarum''. The type species is ''Salsola soda'' L. The genus ''Salsola'' belongs to the tribe Salsoleae ''s.s.'' of the subfamily Salsoloideae in the family Amaranthaceae. The genus was recircumscrib ...

Artemisia Maritima
''Artemisia maritima'' is a European species of wormwood known as sea wormwood and old woman. It is native to France, the United Kingdom, Italy, Belgium, Germany, Denmark, Sweden, Bulgaria and Russia. In its many variations of form it has an extremely wide distribution in the northern hemisphere of the Old World, occurring mostly in saltish soils. It is found in the salt marshes of the British Isles, on the coasts of the Baltic, of France and the Mediterranean, and on saline soils in Hungary; thence it extends eastwards, covering immense tracts in Southern Russia, the region of the Caspian Sea and Central Siberia to Chinese Mongolia. In Britain it is found as far as Wigton on the West and Aberdeen on the East; also in north-east Ireland and in the Channel Islands. It can be also found in Italy, on the Northern Adriatic coast. ''Artemisia maritima'' is a deciduous shrub growing to 0.6 m (2 ft). It iflowers from August to September. The flowers and are pollinated by Wind. The p ...

Nocturnality
Nocturnality is an animal behavior characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing, smell, and specially adapted eyesight. Some animals, such as cats and ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsiers and some owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intense sunlight. Diurnal animals, including squirrels and songbirds, are active d ...
