Khongoryn Els
Khongoryn Els (Khongor Sand, zh, 洪戈尔沙漠) also called ''Duut Mankhan'' is popularly known as the "Singing Sands". It lies within the Gobi Gurvansaikhan National Park in Mongolia. The sand dunes extend to over area. Location The dunes extending up to the foot of the high Altai Mountains range, lie about from Dalanzadgad. It is at a distance of along the desert tracks to Bogd, Ovorkhangai, Bogd in Övörkhangai in the north, and to Bayanlig on the northwest in Bayankhongor. Travel through the desert is by vans. Features Mongolia has three types of deserts, and some of it has enough grass for livestock to graze, but the Khongoryn Els, in the extreme south of the Gobi Desert, has a huge range of sand dunes – wide, long ( is also mentioned) and rising to a height of (a maximum height to the apex can be ). They are similar to the dunes of Egypt. The sands have attractive curves which end in a sharp edge, making wave like patterns on the sand. They continually change ...

Nomad
A nomad is a member of a community without fixed habitation who regularly moves to and from the same areas. Such groups include hunter-gatherers, pastoral nomads (owning livestock), tinkers and trader nomads. In the twentieth century, the population of nomadic pastoral tribes slowly decreased, reaching an estimated 30–40 million nomads in the world . Nomadic hunting and gathering—following seasonally available wild plants and game—is by far the oldest human subsistence method. Pastoralists raise herds of domesticated livestock, driving or accompanying them in patterns that normally avoid depleting pastures beyond their ability to recover. Nomadism is also a lifestyle adapted to infertile regions such as steppe, tundra, or desert, ice and sand, where mobility is the most efficient strategy for exploiting scarce resources. For example, many groups living in the tundra are reindeer herders and are semi-nomadic, following forage for their animals. Sometimes also described as ...

Ecoregions Of Asia
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deserts Of Mongolia
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Fox
The red fox (''Vulpes vulpes'') is the largest of the true foxes and one of the most widely distributed members of the Order (biology), order Carnivora, being present across the entire Northern Hemisphere including most of North America, Europe and Asia, plus parts of North Africa. It is listed as least concern by the IUCN. Its range has increased alongside human expansion, having been Foxes in Australia, introduced to Australia, where it is considered harmful to native mammals and bird populations. Due to its presence in Australia, it is included on the list of the List of the world's 100 worst invasive species, "world's 100 worst invasive species". The red fox originated from smaller-sized ancestors from Eurasia during the Middle Villafranchian period, and colonised North America shortly after the Wisconsin glaciation. Among the true foxes, the red fox represents a more progressive form in the direction of Carnivore, carnivory. Apart from its large size, the red fox is disting ...

Corsac Fox
The corsac fox (''Vulpes corsac''), also known simply as a corsac, is a medium-sized fox found in steppes, semi-deserts and deserts in Central Asia, ranging into Mongolia and northern China. Since 2004, it has been classified as ''least concern'' by IUCN, but populations fluctuate significantly, and numbers can drop tenfold within a single year. It is also known as the steppe fox. The word "corsac" is derived from the Russian name for the animal, ''"korsák"'' (корса́к), derived ultimately from Turkic "karsak". Description The Corsac fox is a medium-sized fox, with a head and body length of , and a tail long. Adults weigh from . It has grey to yellowish fur over much of the body, with paler underparts and pale markings on the mouth, chin, and throat. During the winter, the coat becomes much thicker and silkier in texture, and is straw-grey in colour, with a darker line running down the back. For a fox, it has small teeth and a wide skull. One source claims that this spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saxaul Sparrow
The saxaul sparrow (''Passer ammodendri'') is a passerine bird of the Old World sparrow, sparrow family (biology), family Passeridae, found in parts of Central Asia. At and , it is among the larger sparrows. Both sexes have plumage ranging from dull grey to sandy brown, and pale brown legs. Females have less boldly coloured plumage and bills, lacking the pattern of black stripes on the male's head. The head markings of both sexes make the saxaul sparrow distinctive, and unlikely to be confused with any other bird. Bird vocalization, Vocalisations include a comparatively soft and musical chirping call, a song, and a flight call. Three subspecies are recognised, differing in the overall tone of their plumage and in the head striping of the female. The subspecies ''ammodendri'' occurs in the west of the saxaul sparrow's range, while ''stoliczkae'' and ''nigricans'' occur in the east. This distribution falls into six probably disjunct areas across Central Asia, from central Turkmeni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pallas's Sandgrouse
Pallas's sandgrouse (''Syrrhaptes paradoxus'') is a medium to large bird in the sandgrouse family. Naming Marco Polo mentions a bird called ''Bargherlac'' (from Turkmen ''bağırlak'') in ''The Travels of Marco Polo'', published around 1300. This is probably ''Syrrhaptes paradoxus ''(''S. pallasii''). Pallas's sandgrouse is named after the German zoologist Peter Simon Pallas. The scientific name is from Ancient Greek. The genus ''Syrrhaptes'' is from ''surrhaptos'', meaning "sewn together" (the feathered toes of both species in the genus are fused together) and ''paradoxus'' is from ''paradoxos'', meaning "strange". Description Pallas's sandgrouse is long with small, pigeon-like head and neck, but sturdy compact body. It has long pointed wings and tail and legs and toes are feathered. Its plumage is buff-coloured, barred above with a black belly patch and pale underwings. The black belly and pale underwing distinguish this species from the related Tibetan sandgrouse. The ...

Saker Falcon
The saker falcon (''Falco cherrug'') is a large species of falcon. This species breeds from central Europe eastwards across the Palearctic to Manchuria. It is mainly migratory except in the southernmost parts of its range, wintering in Ethiopia, the Arabian peninsula, northern Pakistan and western China. The saker falcon is the national bird of Hungary, the United Arab Emirates, and Mongolia. Taxonomy and systematics This species belongs to the close-knit hierofalcon complex. In this group, there is ample evidence for rampant hybridization and incomplete lineage sorting which confounds analyses of DNA sequence data to a massive extent; molecular studies with small sample sizes can simply not be expected to yield reliable conclusions in the entire hierofalcon group. The radiation of the entire living diversity of hierofalcons seems to have taken place in the Eemian interglacial at the start of the Late Pleistocene, a mere 130,000–115,000 years ago; the saker falcon represents ...

Gobi Gurvansaikhan National Park
Gobi Gurvansaikhan National Park (, ''Gobi three beauties nature complex'') is a national park in southern Mongolia. The park was established in 1993, and expanded to its current size in 2000. The park, at nearly 27,000 square kilometers, is the largest national park in Mongolia, stretching 380 km from east to west and 80 km from north to south. The park is named for the Gurvan Saikhan Mountains, which translates to the ''Three Beauties''. The name is derived from three subranges, the East, Middle and West Beauty. The range forms the eastern half of the park. The park lies on the northern edge of the Gobi desert. The higher elevations contain areas of steppe, and reach elevations of up to 2,600 meters. A number of rare plants and animals are found in the park, including the elusive snow leopard and the Gobi camel. Areas of sand dunes are found, most famously the Khongoryn Els - the Singing Sands. Another major tourist destination is Yolyn Am, which is conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west.
