Peter Simon Pallas
Peter Simon Pallas Fellow of the Royal Society, FRS FRSE (22 September 1741 – 8 September 1811) was a Prussian zoologist and botanist who worked in Russia between 1767 and 1810. Life and work Peter Simon Pallas was born in Berlin, the son of Professor of Surgery Simon Pallas. He studied with private tutors and took an interest in natural history, later attending the University of Halle and the University of Göttingen. In 1760, he moved to the University of Leiden and passed his doctor's degree at the age of 19. Pallas travelled throughout the Netherlands and to London, improving his medical and surgical knowledge. He then settled at The Hague, and his new system of animal classification was praised by Georges Cuvier. Pallas wrote ''Miscellanea Zoologica'' (1766), which included descriptions of several vertebrates new to science which he had discovered in the Dutch museum collections. A planned voyage to southern Africa and the East Indies fell through when his father reca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained g ...

Birds Of North Asia
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. Bird ...

Rhodopechys Mongolica
The Mongolian finch (''Bucanetes mongolicus''), also known as the Mongolian trumpeter finch, is a small passerine bird in the finch family Fringillidae. Description The Mongolian finch is a small, long-winged bird. It has a large head and short, thick greyish-yellow bill. In breeding plumage, males have a pink flush to their face and underparts, and there are extensive white and pink areas in the wings, a pattern that is also present but less marked in non-breeding plumage. Taxonomy This species has been genetically included in a group of arid-zone Carduelini finches, which comprises the following species: '' Leucosticte arctoa tephrocotis'', '' Leucosticte arctoa arctoa'', '' Carpodacus nipalensis'', '' Rhodopechys githaginea'', '' Rhodopechys mongolica''. Its phylogeny has been obtained by Antonio Arnaiz-Villena et al.

Rhodopechys Githaginea
The trumpeter finch (''Bucanetes githagineus'') is a small passerine bird in the finch family Fringillidae. It is mainly a desert species which is found in North Africa and Spain through to southern Asia. It has occurred as a vagrant in areas north of its breeding range. Distribution and subspecies The trumpeter finch breeds from the Canary Islands eastwards across North Africa, as far south as Mauritania, Mali and Chad, with isolated populations in Sudan and Ethiopia and Djibouti. In the Middle East, it is found in Egypt east to Iraq and south in the Arabian Peninsula to Yemen and Oman and north into Turkey and Armenia. In central Asia it ranges from Iran north to Kazakhstan and east to India. It has colonised southern Spain where breeding was first proved in 1971. There are four recognised subspecies: * ''B. g. amantum'' - (Hartert, 1903) - the Canary Islands * ''B. g. zedlitzi'' - (Neumann, 1907) - North Africa and southeastern Spain * ''B. g. githagineus'' ( Lichtenstein, ...

Carpodacus Nipalensis
The dark-breasted rosefinch (''Procarduelis nipalensis'') is a species of true finch in the monotypic genus ''Procarduelis''. It is found in Bhutan, China, India, Laos, Myanmar, Nepal, Pakistan, Thailand, and Vietnam. Its natural habitats are boreal forests and subtropical or tropical high-altitude shrubland. Taxonomy The dark-breasted rosefinch was formerly placed in the genus ''Carpodacus'' but was moved ''Procarduelis'' based on the results from the phylogenetic analyses of mitochondrial and nuclear DNA sequences. Subspecies Subspecific variation is mostly clinal, with the plumage becoming darker from west to east. There are between two-three recognised subspecies: * ''P. n. nipalensis'' – Hodgson, 1836: The nominate, it is found in the Himalayas, from Kumaon to Nepal, Sikkim, Bhutan, and southeastern Tibet. Populations from southwestern China, south Tibet, and northern Vietnam are sometimes separated as a distinct subspecies, ''P. n. intensicolor''. * ''P. n. kangrae'' ...

Grassland
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessment of Global Ecosystems, 2000) * "A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finch
The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes species known as siskins, canaries, redpolls, serins, grosbeaks and euphonias. Many birds in other families are also commonly called "finches". These groups include the estrildid finches (Estrildidae) of the Old World tropics and Australia; some members of the Old World bunting family (Emberizidae) and the New World sparrow family (Passerellidae); and the Darwin's finches of the Galapagos islands, now considered members of the tanager family (Thraupidae).Newton (1973), Clement ''et al.''
