Palearctic Realm
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/ Afrotropic, Indian/ Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred ...

Ecoregions Of Mongolia
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Azas Nature Reserve
Azas Nature Reserve (russian: Азас заповедник) is a Russian 'Zapovednik' (strict nature reserve), located in the central part of the Todzha basin (a large intermountain trough within the Altai-Sayan mountain region) of south-central Asia about 500 km west of Lake Baikal. The reserve stretches along the Azas River, and is situated in the Todzhinsky District of Tuva. Topography The reserve covers a dense network of rivers and lakes in the mountain headwaters of what eventually becomes the Yenisei River. The primary river is the Azas River, which flows into Todzha Lake (Todzha is another name for Azas), before flowing out again as the Toora-Khem River. The base rock is Proterozoic and Paleozoic (that is, older than 250 million years) sandstones, limestones and various intrusions. In most of the territory this is covered with recent (Quaternary) moraine and fluvial sediments. Located in the glacially-created Todzha Basin, the reserve itself is mid-level in altit ...

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 ...

Snow Leopard
The snow leopard (''Panthera uncia''), also known as the ounce, is a felid in the genus '' Panthera'' native to the mountain ranges of Central and South Asia. It is listed as Vulnerable on the IUCN Red List because the global population is estimated to number fewer than 10,000 mature individuals and is expected to decline about 10% by 2040. It is threatened by poaching and habitat destruction following infrastructural developments. It inhabits alpine and subalpine zones at elevations of , ranging from eastern Afghanistan, the Himalayas and the Tibetan Plateau to southern Siberia, Mongolia and western China. In the northern part of its range, it also lives at lower elevations. Taxonomically, the snow leopard was long classified in the monotypic genus ''Uncia''. Since phylogenetic studies revealed the relationships among ''Panthera'' species, it has been considered a member of that genus. Two subspecies were described based on morphological differences, but genetic differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altai Nature Reserve
Altai Nature Reserve (russian: Алтайский заповедник, also called ) is a Russian ('sanctuary, strict nature reserve') in the Altai Mountains of south Siberia, Russia.

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subalpine Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50° to 70°N, poleward of the humid continental climates. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'', ''Dwd'' and ''Dsd''. Description This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below and in summer, the temperature may exceed . However, the summers are short; no more than three months of the year (but at least one month) must have a 24-hour average temperature of at least to fall into this category of climate, and the coldest month should ave ...
