Trans-Baikal Conifer Forests
The Trans-Baikal conifer forests ecoregion (WWF ID: PA0609) covers a 1,000 km by 1,000 km region of mountainous southern taiga stretching east and south from the shores of Lake Baikal in the Southern Siberia region of Russia, and including part of northern Mongolia. Historically, the area has been called "Dauria", or Transbaikal ("the land beyond Lake Baikal"). It is in the Palearctic realm, and mostly in the boreal forests/taiga biome with a subarctic, humid climate. It covers . Location and description The ecoregion is centered on the Yablonoi Mountains, a range that reaches heights of , and runs southwest to northeast, parallel to Lake Baikal. The western edge of the region is the eastern shore of Lake Baikal and the Barguzin mountain range. The city of Chita is at the northeast of the region, and the city of Ulaanbaatar, Mongolia, is just outside the southern point of the region. To the south are the Khentii Mountains in Mongolia. To the east are the temp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palearctic
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 Wallace a ...

Daurian Forest Steppe
The Daurian forest steppe ecoregion (WWF ID: PA0804) is a band of grassland, shrub terrain, and mixed forests in northeast Mongolia and the region of Siberia, Russia that follows the course of the Onon River and Ulz River. The region has been described as a “sea of grass that forms the best and most intact example of an undisturbed steppe ecosystem and is also one of the last areas in the Palearctic that still supports stable herds of larger vertebrates” in a semi-mountainous area. The area also has flat wetlands that are important to migratory birds. The ecoregion is in the Palearctic realm, with a dry-winter subarctic climate ( Köppen ''Dwc'') that borders on a very cold semi-arid climate (''BSk'') in its southwestern parts. It covers . Location and description The ecoregion circles around half of the Khentii Mountains, then stretches over 1,000 kilometers east of Ulan Bator into northeasteastern Mongolia through the semi-arid region south and east of Chita, Zabaykalsky ...

Pinus Sylvestris
''Pinus sylvestris'', the Scots pine (UK), Scotch pine (US) or Baltic pine, is a species of tree in the pine family Pinaceae that is native to Eurasia. It can readily be identified by its combination of fairly short, blue-green leaves and orange-red bark. Description ''Pinus sylvestris'' is an evergreen coniferous tree growing up to in height and in trunk diameter when mature, exceptionally over tall and in trunk diameter on very productive sites. The tallest on record is a tree over 210 years old tree growing in Estonia which stands at . The lifespan is normally 150–300 years, with the oldest recorded specimens in Lapland, Northern Finland over 760 years. The bark is thick, flaky and orange-red when young to scaly and gray-brown in maturity, sometimes retaining the former on the upper portion.Trees for LifeSpecies profile: Scots pine/ref> The habit of the mature tree is distinctive due to its long, bare and straight trunk topped by a rounded or flat-topped mass of ...

Pinus Sibirica
''Pinus sibirica'', or Siberian pine, in the family Pinaceae is a species of pine tree that occurs in Siberia from 58°E in the Ural Mountains east to 126°E in the Stanovoy Range in southern Sakha Republic, and from Igarka at 68°N in the lower Yenisei valley, south to 45°N in central Mongolia. Description ''Pinus sibirica'' is a member of the white pine group, ''Pinus'' subgenus ''Strobus'', and like all members of that group, the leaves ('needles') are in fascicles (bundles) of five, with a deciduous sheath. They are 5–10 cm long. Siberian pine cones are 5–9 cm long. The 9–12 mm long seeds have only a vestigial wing and are dispersed by spotted nutcrackers. Siberian pine is treated as a variety or subspecies of the very similar Swiss pine (''Pinus cembra'') by some botanists. It differs in having slightly larger cones, and needles with three resin canals instead of two in Swiss pine. Like other European and Asian white pines, Siberian pine is very resis ...

Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSk'' and ''BSh'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as it usually can't support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): *multiply by ...

Humid Continental Climate
A humid continental climate is a climatic region defined by Russo-German climatologist Wladimir Köppen in 1900, typified by four distinct seasons and large seasonal temperature differences, with warm to hot (and often humid) summers and freezing cold (sometimes severely cold in the northern areas) winters. Precipitation is usually distributed throughout the year but often do have dry seasons. The definition of this climate regarding temperature is as follows: the mean temperature of the coldest month must be below or depending on the isotherm, and there must be at least four months whose mean temperatures are at or above . In addition, the location in question must not be semi-arid or arid. The cooler ''Dfb'', ''Dwb'', and ''Dsb'' subtypes are also known as hemiboreal climates. Humid continental climates are generally found between latitudes 30° N and 60° N, within the central and northeastern portions of North America, Europe, and Asia. They are rare and isolat ...

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'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
