Goat-antelope
The subfamily Caprinae, also sometimes referred to as the tribe Caprini, is part of the ruminant family (biology), family Bovidae, and consists of mostly medium-sized bovids. A member of this subfamily is called a caprine. Prominent members include Ovis, sheep and Capra (genus), goats, with some other members referred to as goat antelopes. Some earlier Taxonomy (biology), taxonomies considered Caprinae a separate family called Capridae (with the members being caprids), but now it is usually considered either a subfamily within the Bovidae, or a tribe within the subfamily Antilopinae of the family Bovidae, with caprines being a type of bovid. Characteristics Although most goat-antelopes are gregarious and have fairly stocky builds, they diverge in many other ways – the muskox (''Ovibos moschatus'') is adapted to the extreme cold of the tundra; the mountain goat (''Oreamnos americanus'') of North America is specialised for very rugged terrain; the urial (''Ovis orientalis'') ...

Antilocapridae
The Antilocapridae are a family of ruminant artiodactyls endemic to North America. Their closest extant relatives are the giraffids. Only one species, the pronghorn (''Antilocapra americana''), is living today; all other members of the family are extinct. The living pronghorn is a small ruminant mammal resembling an antelope. Description In most respects, antilocaprids resemble other ruminants. They have a complex, four-chambered stomach for digesting tough plant matter, cloven hooves, and small, forked horns. Their horns resemble those of the bovids, in that they have a true horny sheath, but, uniquely, they are shed outside the breeding season, and subsequently regrown. Their lateral toes are even further diminished than in bovids, with the digits themselves being entirely lost, and only the cannon bones remaining. Antilocaprids have the same dental formula as most other ruminants: . Classification The antilocaprids are ruminants of the clade Pecora. Other extant pecor ...

Tundra
In physical geography, a tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: #Arctic, Arctic, Alpine tundra, Alpine, and #Antarctic, Antarctic. Tundra vegetation is composed of dwarf shrubs, Cyperaceae, sedges, Poaceae, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained greenhouse gases into the atmosphere, creating Climate change feedback, a feedback cycle t ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeoreas Lindermayeri
''Palaeoreas'' was a genus of Miocene bovid from Europe. Geographic range ''Palaeoreas lindermayeri'' fossils have been found in Bulgaria and Greece. Palaeoecology Based on fossils from Pikermi and Samos, ''P. lindermayeri'' is believed to have had a browsing Browsing is a kind of orienting strategy. It is supposed to identify something of relevance for the browsing organism. In context of humans, it is a metaphor taken from the animal kingdom. It is used, for example, about people browsing open sh ... feeding style. However, dental wear patterns on ''P. lindermayeri'' remains from northern Greece instead show it to have been a variable grazer or mixed feeder.

Nemorhaedus
The gorals are four species in the genus ''Naemorhedus''. They are small ungulates with a goat-like or antelope-like appearance. Until recently, this genus also contained the serow species (now in genus '' Capricornis''). Etymology The original name is based on Latin ''nemor-haedus'', from ''nemus, nemoris'' 'grove' and ''haedus'' 'little goat', but it was misspelt ''Naemorhedus'' by Hamilton Smith (1827). The name ''goral'' comes from an eastern Indian word for the Himalayan goral. Extant species Habitat Gorals are often found on rocky hillsides at high elevations. Though their territories often coincide with those of the closely related serow, the goral will usually be found on higher, steeper slopes with less vegetation. Characteristics Gorals typically weigh and are in length, with short, backward-facing horns. Coloration differs between species and individuals, but generally ranges from light gray to dark red-brown, with lighter patches on the chest, throat, and und ...

Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages, and greenhouse periods during which there are no glaciers on the planet. Earth is currently in the ice age called Quaternary glaciation. Individual pulses of cold climate within an ice age are termed '' glacial periods'' (''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, the term ''ice age'' is defined by the presence of extensive ice sheets in the northern and southern hemispheres. By this definition, the current Holocene epoch is an interglacial period of an ice age. The accumulation of anthropogenic greenhouse gases is projected to delay the next glacial period.

Domestic Sheep
Sheep (: sheep) or domestic sheep (''Ovis aries'') are a domesticated, ruminant mammal typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus '' Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' ( ), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat ( lamb, hogget or mutton), and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armenian Mouflon
The Armenian mouflon (''Ovis orientalis gmelini'') is an endangered subspecies of mouflon endemic to Iran, Armenia, Nakhchivan Autonomous Republic of Azerbaijan, Turkey and Iraq. Taxonomy The Armenian mouflon was first described in 1840 by Edward Blyth, who equated it with the "Orientalische Schaaf" (Oriental sheep) described by Samuel Gottlieb Gmelin in 1774. It is known as the Armenian mouflon in both , ''haykakan muflon'' and , ''Qutch-e armani''. Alternative names include Armenian wild sheep, Armenian red sheep, Transcaucasian mountain sheep, Transcaucasian sheep. and Anatolian mouflon. Distribution and population In Iran, Armenian mouflons are found in the northwestern part of the country. Individuals were transferred to Kabudan Island in Lake Urmia in 1895 and 1906 by one of the governors of Iranian Azerbaijan. A study carried out in the 1970s at the island found that their number declined from around 3,500 in 1970 to 1,000 in 1973. In 2004 1,658 Armenian wild sheep were ...
