Muflon
The mouflon (''Ovis gmelini'') is a wild sheep native to Cyprus, the Caspian region from eastern Turkey, Armenia, Azerbaijan, and Iran. It is thought to be the ancestor of all modern domestic sheep breeds. Taxonomy ''Ovis gmelini'' was the scientific name proposed by Edward Blyth in 1841 for wild sheep in the Middle East. In the 19th and 20th centuries, several wild sheep were described that are considered mouflon subspecies today: * ''Ovis ophion'' by Blyth in 1841 for wild sheep in Cyprus; * ''Ovis laristanica'' by Nikolai Nasonov in 1909 for wild sheep in Lar in southern Iran; * ''Ovis orientalis isphahanica'' by Nasonov in 1910 for wild sheep in the Zagros Mountains. Subspecies Five mouflon subspecies of are distinguished by MSW3: * Armenian mouflon (Armenian red sheep), ''O. g. gmelini'' : nominate subspecies; native to northwestern Iran, Armenia, and Azerbaijan. It has been introduced to Texas in the U.S. * Esfahan mouflon, ''O. g. isphahanica'' : Zagros Mountains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Mouflon
The European mouflon (''Ovis aries musimon'') is a feral subspecies of the primitive domestic sheep. It was originally found only on the Mediterranean islands of Corsica and Sardinia, but has since been introduced into many other regions of Europe. It is not to be confused with ''Ovis gmelini'', also called the mouflon, which is found in Western Asia and is also ancestral to modern domestic sheep. Description Male mouflon are known as rams and the females as ewes. The young animals are known as lambs. Appearance European mouflon have a body length of up to 120 cm, a shoulder height of 90 cm, a weight of 25 to 40 kg for ewes, 35 to 55 kg for the ram. The European mouflon has a smooth hairy coat, the rams are fox red-brown in the summer, usually with a whitish saddle patch, the ewes are brownish. Both sexes are darker in winter.

Cyprus
Cyprus ; tr, Kıbrıs (), officially the Republic of Cyprus,, , lit: Republic of Cyprus is an island country located south of the Anatolian Peninsula in the eastern Mediterranean Sea. Its continental position is disputed; while it is geographically in Western Asia, its cultural ties and geopolitics are overwhelmingly Southern European. Cyprus is the third-largest and third-most populous island in the Mediterranean. It is located north of Egypt, east of Greece, south of Turkey, and west of Lebanon and Syria. Its capital and largest city is Nicosia. The northeast portion of the island is ''de facto'' governed by the self-declared Turkish Republic of Northern Cyprus, which was established after the 1974 invasion and which is recognised as a country only by Turkey. The earliest known human activity on the island dates to around the 10th millennium BC. Archaeological remains include the well-preserved ruins from the Hellenistic period such as Salamis and Kourion, and Cypr ...

Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urial
The urial ( ; ''Ovis vignei''), also known as the arkars or shapo, is a wild sheep native to Central and South Asia. It is listed as Vulnerable on the IUCN Red List.

Argali
The argali (''Ovis ammon''), also known as the mountain sheep, is a wild sheep that roams the highlands of western East Asia, the Himalayas, Tibet, and the Altai Mountains. Description The name 'argali' is the Mongolian word for wild sheep. It is the largest species of wild sheep. Argali stand high at the shoulder and measure long from the head to the base of the tail. The female, or ewe is the smaller sex by a considerable margin, sometimes weighing less than half as much as the male, or ram. The ewes can weigh from and the rams typically from , with a maximum reported mass of . The Pamir argali (also called Marco Polo sheep, for they were first described by that traveler), ''O. a. polii'', is the largest race on average, regularly measuring more than long without the tail, and is less sexually dimorphic in body mass than most other subspecies. The argali has relatively the shortest tail of any wild goat-antelope or sheep, with reported tail lengths of . The general colo ...

Bighorn
The bighorn sheep (''Ovis canadensis'') is a species of sheep native to North America. It is named for its large horns. A pair of horns might weigh up to ; the sheep typically weigh up to . Recent genetic testing indicates three distinct subspecies of ''Ovis canadensis'', one of which is endangered: ''O. c. sierrae''. Sheep originally crossed to North America over the Bering Land Bridge from Siberia; the population in North America peaked in the millions, and the bighorn sheep entered into the mythology of Native Americans. By 1900, the population had crashed to several thousand, due to diseases introduced through European livestock and overhunting. Taxonomy and genetics ''Ovis canadensis'' is one of two species of mountain sheep in North America; the other species being ''O. dalli'', the Dall sheep. Wild sheep crossed the Bering land bridge from Siberia into Alaska during the Pleistocene (about 750,000 years ago) and subsequently spread through western North America as far s ...

Ovis
''Ovis'' is a genus of mammals, part of the Caprinae subfamily of the ruminant family Bovidae. Its seven highly sociable species are known as sheep or ovines. Domestic sheep are members of the genus, and are thought to be descended from the wild mouflon of central and southwest Asia. Terminology Female sheep are called ''ewes'', males are called ''rams'' or less frequently ''bucks'' or ''tups'', neutered males are called ''wethers'', and young sheep are called ''lambs''. The adjective applying to sheep is ''ovine'', and the collective term for sheep is ''flock'' or ''mob''. The term ''herd'' is also occasionally used in this sense, generally for large flocks. Many specialist terms relating to domestic sheep are used. Characteristics Sheep are fairly small compared to other ungulates; in most species, adults weigh less than .Nowak, R. M. and J. L.

Cytochrome B
Cytochrome b within both molecular and cell biology, is a protein found in the mitochondria of eukaryotic cells. It functions as part of the electron transport chain and is the main subunit of transmembrane cytochrome bc1 and b6f complexes. Function In the mitochondrion of eukaryotes and in aerobic prokaryotes, cytochrome b is a component of respiratory chain complex III () — also known as the bc1 complex or ubiquinol-cytochrome c reductase. In plant chloroplasts and cyanobacteria, there is an analogous protein, cytochrome b6, a component of the plastoquinone-plastocyanin reductase (), also known as the b6f complex. These complexes are involved in electron transport, the pumping of protons to create a proton-motive force ( PMF). This proton gradient is used for the generation of ATP. These complexes play a vital role in cells. Structure Cytochrome b/b6 is an integral membrane protein of approximately 400 amino acid residues that probably has 8 transmembrane segments. ...
