Zapovedniks
Zapovednik (russian: заповедник, plural , from the Russian , 'sacred, prohibited from disturbance, committed o protect committed o heritage; ) is an established term on the territory of the former Soviet Union for a protected area which is kept "forever wild". It is the highest degree of environmental protection for the assigned areas, which are strictly protected and access to the public is restricted. Overview The literal English translation of ''zapovednik'' is "nature sanctuary" (like animal sanctuary); however, in practice, zapovedniks sometimes have to do with the protection of things other than nature and can incorporate historical-cultural, historical–archaeological, and other types of cultural or natural heritage. They also function as important sites for historical research and education and so are comparable to the Sites of Special Scientific Interest as found in the United Kingdom and Hong Kong. The term ''zapovednik'', which refers to the reserve, staff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barguzin Nature Reserve
Barguzinsky Nature Reserve (russian: Баргузинский заповедник) is the oldest of ''zapovedniks'' (nature reserves). It is located in Buryatia (Russia) on the west slope of the Barguzin Range, including the northeast shores of the Lake Baikal and a part of the lake itself. The name of the preserve (and the range) comes from the Barguzin River. The area of the reserve is . It was created in 1916 to preserve and increase the numbers of Barguzin Sable (''Martes zibellina''). Mountainous and taiga landscapes are also being preserved. The mountain landscape is intersected by glaciers and lakes. Ecoregion and climate The Barguzin Reserve is located in the Trans-Baikal conifer forests ecoregion. This ecoregion covers a mountainous region of southern taiga stretching east, and south from the shores of Lake Baikal in southern Russia, reaching into northern Mongolia. The climate of Barguzin is a ''Subarctic climate'' with dry winters (Köppen climate classification S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vasily Dokuchaev
Vasily Vasilyevich Dokuchaev (russian: Васи́лий Васи́льевич Докуча́ев; 1 March 1846 – 8 November 1903) was a Russian geologist and geographer who is credited with laying the foundations of soil science. The Ukrainian city of Dokuchaievsk is named after him. Overview Vasily Vasilevich Dokuchaev is commonly regarded as the father of soil science, the study of soils in their natural setting. He developed soil science in Russia, and was perhaps the first person to conduct broad geographical investigations of different soil types. His contribution to science did, figuratively, "put soils on the map". He introduced the idea that the geographical variations in soil type could be explained by other variables besides geological factors (parent material), such as climatic and topographic factors, and by the period of time since the initial pedogenesis (soil formation). Using these ideas as a starting point, he developed the very first soil classific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montane Ecology
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Nikita Khrushchev
Nikita Sergeyevich Khrushchev (– 11 September 1971) was the First Secretary of the Communist Party of the Soviet Union from 1953 to 1964 and chairman of the country's Council of Ministers from 1958 to 1964. During his rule, Khrushchev stunned the communist world with his denunciation of his predecessor Joseph Stalin's crimes, and embarked on a policy of de-Stalinization with his key ally Anastas Mikoyan. He sponsored the early Soviet space program, and enactment of moderate reforms in domestic policy. After some false starts, and a narrowly avoided nuclear war over Cuba, he conducted successful negotiations with the United States to reduce Cold War tensions. In 1964, the Kremlin leadership stripped him of power, replacing him with Leonid Brezhnev as First Secretary and Alexei Kosygin as Premier. Khrushchev was born in 1894 in a village in western Russia. He was employed as a metal worker during his youth, and he was a political commissar during the Russian Civil Wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
