Azerbaijani Mouse-like Hamster
The Urar mouse-like hamster or Azerbaijani mouse-like hamster (''Calomyscus urartensis'') is a medium-sized mouse-like hamster from Nakhichevan, Azerbaijan and northwestern Azarbaijan Province, Iran. It is among the better studied representatives of this poorly known genus. The initial species description was based on a unique chromosome number (2n=32; FNa=42) called a karyotype A karyotype is the general appearance of the complete set of metaphase chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. Karyotyping is the process by which a karyotype is disce .... The species status has been confirmed with other chromosomal studies and morphometric studies.

They are found in rocky outcrops and semi-mountainous areas in desert regions. The mouse-like hamsters are not true hamsters, but represent an early split from the rest of the Muroidea, mouse-like rodents. They were once thought to be hamsters based on the shape of their molars, but they lack the cheek pouches, flank glands and short tails of the true hamsters. The closest relatives of the mouse-like hamsters may be the extinct Cricetodontidae. Because of their seemingly early break from the rest of the mouse-like rodents, mouse-like hamsters have been placed in a family of their own, Calomyscidae, and have been referred to as living fossils. All members of the genus were once considered part of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nakhichivan Autonomous Republic
The Nakhchivan Autonomous Republic ( az, Naxçıvan Muxtar Respublikası, ), is a landlocked exclave of the Republic of Azerbaijan. The region covers Official portal of Nakhchivan Autonomous RepublicNakhchivan Autonomous Republic with a population of 459,600 bordered by Armenia to the east and north, Iran to the southwest, and Turkey to the west. The republic, especially the capital city of Nakhchivan, has a long history dating back to about 1500 BCE. ''Nakhijevan'' was one the cantons of the historical Armenian province of Vaspurakan in the Kingdom of Armenia. Historically though, the Persians, Armenians, Mongols, and Turks all competed for the region. The area that is now Nakhchivan became part of Safavid Iran in the 16th century. In 1828, after the last Russo-Persian War and the Treaty of Turkmenchay, the Nakhchivan Khanate passed from Iranian into Imperial Russian possession. After the 1917 February Revolution, Nakhchivan and its surrounding region were under the authority ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azerbaijan
Azerbaijan (, ; az, Azərbaycan ), officially the Republic of Azerbaijan, , also sometimes officially called the Azerbaijan Republic is a transcontinental country located at the boundary of Eastern Europe and Western Asia. It is a part of the South Caucasus region and is bounded by the Caspian Sea to the east, Russia (Republic of Dagestan) to the north, Georgia to the northwest, Armenia and Turkey to the west, and Iran to the south. Baku is the capital and largest city. The Azerbaijan Democratic Republic proclaimed its independence from the Transcaucasian Democratic Federative Republic in 1918 and became the first secular democratic Muslim-majority state. In 1920, the country was incorporated into the Soviet Union as the Azerbaijan SSR. The modern Republic of Azerbaijan proclaimed its independence on 30 August 1991, shortly before the dissolution of the Soviet Union in the same year. In September 1991, the ethnic Armenian majority of the Nagorno-Karabakh region formed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iranian Azarbaijan
Azerbaijan or Azarbaijan ( fa, آذربایجان, ''Āzarbāijān'' ; az-Arab, آذربایجان, ''Āzerbāyjān'' ), also known as Iranian Azerbaijan, is a historical region in northwestern Iran that borders Iraq, Turkey, the Nakhchivan Autonomous Republic, Armenia, and the Republic of Azerbaijan. Iranian Azerbaijan includes three northwestern Iranian provinces: West Azerbaijan, East Azerbaijan and Ardabil. Some authors also include Zanjan in this list, some in a geographical sense, others only culturally (due to the predominance of the Azeri Turkic population there). The region is mostly populated by Azerbaijanis, with minority populations of Kurds, Armenians, Tats, Talysh, Assyrians and Persians. Iranian Azerbaijan is the land originally and historically called Azerbaijan; the Azerbaijani-populated Republic of Azerbaijan appropriated the name of the neighbouring Azerbaijani-populated region in Iran during the 20th century. Historic Azerbaijan was called ''Atropate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chromosome
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated ( S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karyotype
A karyotype is the general appearance of the complete set of metaphase chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes and any abnormalities. A karyogram or idiogram is a graphical depiction of a karyotype, wherein chromosomes are organized in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotyping generally combines light microscopy and photography, and results in a photomicrographic (or simply micrographic) karyogram. In contrast, a schematic karyogram is a designed graphic representation of a karyotype. In schematic karyograms, just one of the sister chromatids of each chromosome is generally shown for brevity, and in reality they are generally so close together that they look as one on photomicrographs as well ...

Calomyscus Bailwardi
The Zagros Mountains mouse-like hamster (''Calomyscus bailwardi'') is a relatively little-known rodent which was the first species of mouse-like hamster to be described. The species is distributed throughout much of southern Iran, particularly in the Zagros mountains. It is also known as the Iranian mouse-like hamster, though there are several species of mouse-like hamster found in different parts of Iran. This is the largest species of mouse-like hamster. They are dark grey on top and white underneath. They are found in habitat ranging from barren rocky hillsides to wetter regions. They are known to feed on herbs and grass seed. Graphodatsky et al.

Mammals Of Western Asia
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 ...

Fauna Of Azerbaijan
Fauna of Azerbaijan or animal kingdom of Azerbaijan refers to the diversity of various types of animals, which inhabit and populate a defined ground or water area in Azerbaijan. The first reports on the richness and diversity of animal life in Azerbaijan can be found in travel notes of Eastern travelers. Animal carvings on architectural monuments, ancient rocks and stones survived up to the present times. The first information on the animal kingdom of Azerbaijan was collected during the visits of naturalists to Azerbaijan in the 17th century. Unlike fauna, the concept of animal kingdom covers not only the types of animals, but also the number of individual species. The symbol of Fauna in Azerbaijan is the Karabakh horse (Azeri: Qarabağ atı) which is a mountain-steppe racing and riding horse which can only be found in Azerbaijan. The Karabakh horse has a reputation for its good temper, speed, elegance and intelligence. It is one of the oldest breeds, with ancestry dating to th ...
