Taimyr–Central Siberian Tundra
The Taimyr-Central Siberian tundra ecoregion (WWF ID: PA1111) is an ecoregion that broadly covers the Taymyr Peninsula in the Far North (Russia), Russian Far North. It ranges from the delta of the Yenisei River in the west, across the Taymyr Peninsula and Khatanga Gulf, to the Lena River delta in the east. The region is an important area for breeding birds. It is in the Palearctic realm in the tundra biome, and is mostly located in Taymyrsky Dolgano-Nenetsky District of Krasnoyarsk Krai. It has an area of . Location and description The Taymyr Peninsula reaches into the Arctic Ocean, between the Kara Sea and the Laptev Sea in northern Siberia. Unlike much of the Arctic North, which is lowland tundra, the Taymyr Peninsula is built around highlands - the Byrranga Mountains. A notable feature of the ecoregion is Lake Taymyr, a large (165 km long) lake in the south of the Byrranga Mountains. The coastal plain to the north is arctic coastal desert and tundra, with terrain to the so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taymyr Nature Reserve
Taymyr Nature Reserve (russian: Таймырский заповедник) (also Taimyrsky) is a Russian 'zapovednik' (strict nature reserve) located in the northern lowlands of Siberia, on the Taimyr Peninsula, and on the coast of the Laptev Sea of the Arctic Ocean. The reserve includes the most northern forest of Dahurian larch in the world, and also the most northern mainland mountain range in the world. The protected area was established to protect the breeding grounds of the Red-breasted goose (Branta ruficollis) as well as the summer residences of wild reindeer (Rangifer tarandus) and the biodiversity of the Lake Taymyr. The reserve is situated about 120 km east of the town of Norilsk, and 3,000 km northeast of Moscow, in the Taymyrsky Dolgano-Nenetsky District of Krasnoyarsk Krai. In 1995, the site was designated a UNESCO MAB (Man and Biosphere) Reserve. The reserve was formally established in 1979, and covers an area of . Topography The Taymyr Reserve protect ...

Thermokarst
Thermokarst is a type of terrain characterised by very irregular surfaces of marshy hollows and small hummocks formed as ice-rich permafrost thaws. The land surface type occurs in Arctic areas, and on a smaller scale in mountainous areas such as the Himalayas and the Swiss Alps. These pitted surfaces resemble clusters of small lakes formed by dissolution of limestone in some karst areas, which is how they came to have "''karst''" attached to their name, even though no limestone is actually present. Small domes that form on the surface due to frost heaving with the onset of winter are only temporary features. They collapse during the following summer thaw, leaving a small surface depression. Some ice lenses grow and form larger surface hummocks ("pingos") which can last for many years, and sometimes become covered with grasses and sedges, until they begin to thaw. These domed surfaces eventually collapse – either annually or after longer periods – and form depressions which bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Branta Ruficollis
The red-breasted goose (''Branta ruficollis'') is a brightly marked species of goose in the genus ''Branta'' from Eurasia. It is currently classified as vulnerable by the IUCN. Taxonomy and etymology The red-breasted goose is sometimes placed in its own genus ''Rufibrenta'' but appears close enough to the brant goose (''Branta bernicla'') to make this unnecessary, despite its distinct appearance. Today all major authorities include the red-breasted goose in ''Branta''. Genetic studies indicate that the red-breasted goose may be one the few known examples of hybrid speciation in birds, being the result of ancient interbreeding between the ancestral brant goose and white-cheeked goose (the latter being the ancestral species that later split into all today's ''Branta'' species, except the brant and red-breasted geese). This interbreeding appears to have happened at least 3.5 million years ago, with the lineage of the red-breasted goose following its own evolutionary path since th ...

Dwarf-shrub
A subshrub (Latin ''suffrutex'') or dwarf shrub is a short shrub, and is a woody plant. Prostrate shrub is a related term. "Subshrub" is often used interchangeably with "bush".Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 Because the criteria are matters of degree (normally of height) rather than of kind, the definition of a subshrub is not sharply distinguishable from that of a shrub; examples of reasons for describing plants as subshrubs include ground-hugging stems or low growth habit. Subshrubs may be largely herbaceous though still classified as woody, with overwintering perennial woody growth much lower-growing than deciduous summer growth. Some plants described as subshrubs are only weakly woody and some persist for only for a few years; others however, such as ''Oldenburgia paradoxa'' live indefinitely (though is still vulnerable to external effects), rooted in rocky cracks. ...

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Forb
A forb or phorb is an herbaceous flowering plant that is not a graminoid (grass, sedge, or rush). The term is used in biology and in vegetation ecology, especially in relation to grasslands and understory. Typically these are dicots without woody stems. Etymology The word "forb" is derived from Greek ''phorbḗ'' (), meaning "pasture" or "fodder". The Hellenic spelling "phorb" is sometimes used, and in older usage this sometimes includes graminids and other plants currently not regarded as forbs. Guilds Forbs are members of a guilda group of plant species with broadly similar growth form. In certain contexts in ecology, guild membership may often be more important than the taxonomic relationships between organisms. In informal classification In addition to its use in ecology, the term "forb" may be used for subdividing popular guides to wildflowers, distinguishing them from other categories such as grasses, sedges, shrubs, and trees. Some examples of forbs are clovers, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
