West Siberian Broadleaf And Mixed Forests
The West Siberian broadleaf and mixed forests, also known as the Western Siberian hemiboreal forests, is an ecoregion (WWF ID: PA0444) in Russia. It consists of a thin band of mixed forest along the southernmost edge of the West Siberian taiga (coniferous forests) in Western Siberia, and north of the forest steppe belt. The biodiversity of the zone is the highest in Siberia, due to its transitional position between many different ecoregions. The area acts as a long corridor for migration of animals along the east-west axis. The ecoregion is in the Palearctic realm, with a Humid Continental climate. It covers . Location and description The ecoregion is an east-west strip, stretching from Chelyabinsk in the west to Krasnoyarsk in the east. The zone is only from north to south. Tomsk City is fairly located in this ecoregion. The Ob River and Irtysh River, and tributaries of those rivers, cross the region from south to north. The southeast of the region breaks up into low mountai ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Abies Sibirica
''Abies sibirica'', the Siberian fir, is a coniferous evergreen tree native to the taiga east of the Volga River and south of 67°40' North latitude in Siberia through Turkestan, northeast Xinjiang, Mongolia and Heilongjiang. Distribution The tree lives in the cold boreal climate on moist soils in mountains or river basins at elevations of 1900–2400 m. It is very shade-tolerant, frost-resistant, and hardy, surviving temperatures down to −50 °C. It rarely lives over 200 years due to the susceptibility to fungal decay in the wood. Description Siberian fir, ''Abies sibirica'', grows 30–35 m tall with a trunk diameter of 0.5–1 m at breast height and a conical crown. The bark is grey-green to grey-brown and smooth with resin blisters typical of most firs. Shoots are yellow-grey, resinous, and slightly pubescent. The leaves are needle-like, 2–3 cm long and 1.5 mm broad on average. They are light green above with two grey- ...

Ecoregions Of Asia
An ecoregion (ecological region) is an ecological and geographic area that exists on multiple different levels, defined by type, quality, and quantity of environmental resources. 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). Ecoregions are also known as "ecozones" ("ecological zones"), although that term may also refer to biogeographic realms. Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framewo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Betula Pubescens
''Betula pubescens'' (syn. ''Betula alba''), commonly known as downy birch and also as moor birch, white birch, European white birch or hairy birch, is a species of deciduous tree, native and abundant throughout northern Europe and northern Asia, growing further north than any other broadleaf tree. It is closely related to, and often confused with, the silver birch (''B. pendula''), but grows in wetter places with heavier soils and poorer drainage; smaller trees can also be confused with the dwarf birch (''B. nana''). Six varieties are recognised and it hybridises with the silver and dwarf birches. A number of cultivars have been developed, but many are no longer in cultivation. The larva of the autumnal moth (''Epirrita autumnata'') feeds on the foliage and in some years, large areas of birch forest can be defoliated by this insect. Many fungi are associated with the tree and certain pathogenic fungi are the causal agents of birch dieback disease. The tree is a pioneer sp ...

Eutrophication
Eutrophication is a general term describing a process in which nutrients accumulate in a body of water, resulting in an increased growth of organisms that may deplete the oxygen in the water; ie. the process of too many plants growing on the surface of a river, lake, etc., often because chemicals that are used to help crops grow have been carried there by rain. Eutrophication may occur naturally or as a result of human actions. Manmade, or cultural, eutrophication occurs when sewage, Industrial wastewater treatment, industrial wastewater, fertilizer runoff, and other nutrient sources are released into the environment. Such nutrient pollution usually causes algal blooms and bacterial growth, resulting in the depletion of dissolved oxygen in water and causing substantial environmental degradation. Many policies have been introduced to combat eutrophication, including the United Nations Development Program (UNDP)'s sustainability development goals. Approaches for prevention and re ...

Populus Tremula
''Populus tremula'' (commonly called aspen, common aspen, Eurasian aspen, European aspen, or quaking aspen) is a species of poplar native to cool temperate regions of the Old World. Description It is a substantial deciduous tree growing to tall by broad, with a trunk attaining over in diameter. The bark is pale greenish-grey and smooth on young trees with dark grey diamond-shaped lenticels, becoming dark grey and fissured on older trees. The adult leaves, produced on branches of mature trees, are nearly round, slightly wider than long, diameter, with a coarsely toothed margin and a laterally flattened petiole long. The flat petiole allows them to tremble in even slight breezes, and is the source of its scientific name, as well as one of its vernacular names "langues de femmes" attributed to Gerard's 17th-century ''Herball''. The leaves on seedlings and fast-growing stems of suckers (root sprouts) are of a different shape, heart-shaped to nearly triangular. They are al ...

Betula Pendula
''Betula pendula'', commonly known as silver birch, warty birch, European white birch, or East Asian white birch, is a species of tree in the family (biology), family Betulaceae, native plant, native to Europe and parts of Asia, though in southern Europe, it is only found at higher altitudes. Its range extends into Siberia, China, and southwest Asia in the mountains of northern Turkey, the Caucasus, and northern Iran. It has been introduced into North America, where it is known as the European white birch or weeping birch and is considered Invasive species, invasive in some states in the United States and parts of Canada. The silver birch is a medium-sized deciduous tree that owes its common name to the white peeling bark on the trunk. The twigs are slender and often pendulous and the leaves are roughly triangular with Glossary of leaf morphology#Edge, doubly serrate margins and turn yellow and brown in autumn before they fall. The flowers are catkins and the light, winged se ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tilia Cordata
''Tilia cordata'', the small-leaved lime or small-leaved linden, is a species of tree in the family Malvaceae, native to much of Europe. Other common names include little-leaf or littleleaf linden, or traditionally in South East England, pry or pry tree. Its range extends from Great Britain, Britain through mainland Europe to the Caucasus and western Asia. In the south of its range it is restricted to high elevations. Description ''Tilia cordata'' is a deciduous tree growing to tall, diameter 1/3 to 1/2 the height, with a trunk up to diameter. The largest known trunk circumference was a specimen in Närke, Sweden, that measured circumference at chest height. There are lime trees in Germany that are said to be over 1000 years old. The bark is smooth and grayish when young, firm with vertical ridges and horizontal fissures when older. The crown is rounded in a formal oval shape to pyramidal. Branching is upright and increases in density with age. The leaf, leaves are alternately ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Scots Pine
''Pinus sylvestris'', the Scots pine (UK), Scotch pine (US), Baltic pine, or European red 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 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. 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 foliage. The shoots are light ...

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 ...
