Tibetan Rosefinch
The Tibetan rosefinch (''Carpodacus roborowskii''), also known as Roborovski's rosefinch, is a species of rosefinch in the finch family Fringillidae. It is sometimes placed in the monotypic genus ''Kozlowia''. It is endemic to the Tibetan Plateau. Its natural habitat is montane tundra. Distribution and habitat The Tibetan rosefinch is found in northeastern Tibet, in the Buckhan Boda Shan, Amne Machin and Kunlun mountains in Qinghai. These birds live among rocky steppes and alpine pastures, in areas with sparse vegetation. Because of its desolate habitat, the Tibetan rosefinch's range is shared with few other birds, aside from Brandt's mountain finch. Behavior Tibetan rosefinches are diurnal. They live mostly on the ground, traveling quickly hopping in search of food. Diet Tibetan rosefinches are ground feeders. They feed mainly on seeds, as well as fragments of flowers including the lousewort (''Pedicularis ''Pedicularis'' is a genus of perennial green root parasite pla ...

Nikolai Przhevalsky
Nikolay Mikhaylovich Przhevalsky (or Prjevalsky;; pl, Nikołaj Przewalski, . – ) was a Russian geographer of Polish descent (he was born in a Polish noble family), and a renowned explorer of Central and East Asia. Although he never reached his ultimate goal, the holy city of Lhasa in Tibet, he traveled through regions then unknown to the West, such as northern Tibet (modern Tibet Autonomous Region), Amdo (now Qinghai) and Dzungaria (now northern Xinjiang). He contributed substantially to European knowledge of Central Asian geography. He also described several species previously unknown to European science: Przewalski's horse, Przewalski's gazelle, and the wild Bactrian camel, all of which are now endangered. He was a mentor of his follower Pyotr Kozlov. Biography Przhevalsky was born in Kimborovo, in the Smolensky Uyezd of the Smolensk Governorate of the Russian Empire in the Polish noble family. He studied there and at the military academy in St. Petersburg. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steppe
In physical geography, a steppe () is an ecoregion characterized by grassland plains without trees apart from those near rivers and lakes. Steppe biomes may include: * the montane grasslands and shrublands biome * the temperate grasslands, savannas and shrublands biome A steppe may be semi-arid or covered with grass or with shrubs or with both, depending on the season and latitude. The term " steppe climate" denotes the climate encountered in regions too dry to support a forest but not dry enough to be a desert. Steppe soils are typically of the chernozem type. Steppes are usually characterized by a semi-arid or continental climate. Extremes can be recorded in the summer of up to and in winter, . Besides this major seasonal difference, fluctuations between day and night are also very great. In both the highlands of Mongolia and northern Nevada, can be reached during the day with sub-freezing readings at night. Mid-latitude steppes feature hot summers and cold wint ...

Endemic Birds Of China
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Tibet
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carpodacus
The rosefinches are a genus, ''Carpodacus'', of passerine birds in the finch family Fringillidae. Most are called "rosefinches" and as the word implies, have various shades of red in their plumage. The common rosefinch is frequently called the "rosefinch". The genus name is from the Ancient Greek terms ''karpos'', "fruit", and ''dakno'', "to bite". The ''Carpodacus'' rosefinches occur throughout Eurasia, but the greatest diversity is found in the Sino-Himalayas suggesting that the species originated in this region. Systematics In 2012, Zuccon and colleagues published a comprehensive molecular phylogenetic analysis of the finch family. Based both on their own results and those published earlier by other groups, they proposed a series of changes to the taxonomy. They found that the three North American rosefinches, namely Cassin's finch, purple finch, and house finch, formed a separate clade that was not closely related to the Palearctic rosefinches.

Pedicularis
''Pedicularis'' is a genus of perennial green root parasite plants currently placed in the family Orobanchaceae (the genus previously having been placed in Scrophulariaceae ''sensu lato''). Description Between 350 and 600 species are accepted by different authorities, mostly from the wetter northern temperate zones, as well as from South America. The highest diversity is in eastern Asia, with 352 species accepted in China alone. Taxonomy The common name lousewort, applied to several species, derives from an old belief that these plants, when ingested, were responsible for lice infestations in livestock. The genus name ''Pedicularis'' is from the Latin ''pediculus'' meaning louse. Selected species *''Pedicularis acaulis'' *''Pedicularis amoena'' *''Pedicularis arguteserrata'' *''Pedicularis ascendens'' *''Pedicularis asparagoides'' *''Pedicularis asplenifolia'' *''Pedicularis attollens'' (little elephant's head) *''Pedicularis baumgartenii'' *''Pedicularis bhutanomuscoide ...

Diurnality
Diurnality is a form of plant and ethology, animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemerality, cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alpine Climate
Alpine climate is the typical weather (climate) for elevations above the tree line, where trees fail to grow due to cold. This climate is also referred to as a mountain climate or highland climate. Definition There are multiple definitions of alpine climate. In the Köppen climate classification, the alpine and mountain climates are part of group ''E'', along with the polar climate, where no month has a mean temperature higher than . According to the Holdridge life zone system, there are two mountain climates which prevent tree growth : a) the alpine climate, which occurs when the mean biotemperature of a location is between . The alpine climate in Holdridge system is roughly equivalent to the warmest tundra climates (ET) in the Köppen system. b) the alvar climate, the coldest mountain climate since the biotemperature is between 0 °C and 1.5 °C (biotemperature can never be below 0 °C). It corresponds more or less to the coldest tundra climates and to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qinghai
Qinghai (; alternately romanized as Tsinghai, Ch'inghai), also known as Kokonor, is a landlocked province in the northwest of the People's Republic of China. It is the fourth largest province of China by area and has the third smallest population. Its capital and largest city is Xining. Qinghai borders Gansu on the northeast, Xinjiang on the northwest, Sichuan on the southeast and the Tibet Autonomous Region on the southwest. Qinghai province was established in 1928 during the period of the Republic of China, and until 1949 was ruled by Chinese Muslim warlords known as the Ma clique. The Chinese name "Qinghai" is after Qinghai Lake, the largest lake in China. The lake is known as Tso ngon in Tibetan, and as Kokonor Lake in English, derived from the Mongol Oirat name for Qinghai Lake. Both Tso ngon and Kokonor are names found in historic documents to describe the region.Gangchen Khishong, 2001. ''Tibet and Manchu: An Assessment of Tibet-Manchu Relations in Five Phases of ...

Kunlun
The Kunlun Mountains ( zh, s=昆仑山, t=崑崙山, p=Kūnlún Shān, ; ug, كۇئېنلۇن تاغ تىزمىسى / قۇرۇم تاغ تىزمىسى ) constitute one of the longest mountain chains in Asia, extending for more than . In the broadest sense, the chain forms the northern edge of the Tibetan Plateau south of the Tarim Basin. The exact definition of Kunlun Mountains varies over time. Older sources used Kunlun to mean the mountain belt that runs across the center of China, that is, Altyn Tagh along with the Qilian and Qin Mountains. Recent sources have the Kunlun range forming most of the south side of the Tarim Basin and then continuing east, south of the Altyn Tagh. Sima Qian (''Records of the Grand Historian'', scroll 123) says that Emperor Wu of Han sent men to find the source of the Yellow River and gave the name Kunlun to the mountains at its source. The name seems to have originated as a semi-mythical location in the classical Chinese text ''Classic of Mounta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
