Siberian Accentor
The Siberian accentor (''Prunella montanella'') is a small passerine bird that breeds in northern Russia from the Ural Mountains eastwards across Siberia. It is migratory, wintering in Korea and eastern China, with rare occurrences in western Europe and northwestern North America. Its typical breeding habitat is subarctic deciduous forests and open coniferous woodland, often close to water, although it also occurs in mountains and spruce taiga. It inhabits bushes and shrubs in winter, frequently near streams, but may also be found in dry grassland and woods. The Siberian accentor has brown upperparts and wings, with bright chestnut streaking on its back and a greyish-brown rump and tail. The head has a dark brown crown and a long, wide pale yellow supercilium ("eyebrow"). All plumages are quite similar. The nest is an open cup in dense shrub or a tree into which the female lays four to six glossy deep blue-green eggs that hatch in about ten days. Adults and chicks feed mainly on ...

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Lena River
The Lena (russian: Ле́на, ; evn, Елюенэ, ''Eljune''; sah, Өлүөнэ, ''Ölüöne''; bua, Зүлхэ, ''Zülkhe''; mn, Зүлгэ, ''Zülge'') is the easternmost of the three great Siberian rivers that flow into the Arctic Ocean (the other two being the Ob and the Yenisey). Permafrost underlies most of the catchment, 77% of which is continuous. It is long, and has a drainage basin of . The Lena is the eleventh-longest river in the world, and the longest river entirely within Russia. Course Originating at an elevation of at its source in the Baikal Mountains south of the Central Siberian Plateau, west of Lake Baikal, the Lena flows northeast across the Lena-Angara Plateau, being joined by the Kirenga, Vitim and Olyokma. From Yakutsk it enters the Central Yakutian Lowland and flows north until joined by its right-hand tributary the Aldan and its most important left-hand tributary, the Vilyuy. After that, it bends westward and northward, flowing between the K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Jean Pierre Vieillot
Louis Pierre Vieillot (10 May 1748, Yvetot – 24 August 1830, Sotteville-lès-Rouen) was a French ornithologist. Vieillot is the author of the first scientific descriptions and Linnaean names of a number of birds, including species he collected himself in the West Indies and North America and South American species discovered but not formally named by Félix de Azara and his translator Sonnini de Manoncourt. He was among the first ornithologists to study changes in plumage and one of the first to study live birds. At least 77 of the genera erected by Vieillot are still in use. Biography Vieillot was born in Yvetot. He represented his family's business interests in Saint-Domingue (Haiti) on Hispaniola, but fled to the United States during the Haitian rebellions that followed the French Revolution. On Buffon's advice, he collected material for the ''Histoire naturelle des oiseaux de l'Amérique Septentrionale,'' the first two volumes of which were published in France beginning i ...

Phylogenetics
In biology, phylogenetics (; from Greek language, Greek wikt:φυλή, φυλή/wikt:φῦλον, φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, Protein, protein Amino acid, amino acid sequences, or Morphology (biology), morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabian Accentor
Radde's accentor (''Prunella ocularis'') is a species of bird in the family Prunellidae. It is found in mountainous parts of Yemen and northern Southwest Asia.

Black-throated Accentor
The black-throated accentor (''Prunella atrogularis'') is a small passerine bird found in the Ural, Tian Shan and Altai Mountains. It is migratory, wintering in Afghanistan and neighboring countries. It is a rare vagrant in western Europe. The black-throated accentor builds a neat nest low in spruce thickets, laying 3-5 unspotted blue eggs. It winters in scrub or cultivation. This is a dunnock-sized bird, in length. It has a streaked dark brown back, somewhat resembling a house sparrow, but adults have a black crown, face patch and throat, and a white supercilium. The breast is orange, and the belly white with orange stripes. Like other accentors, this species has an insectivore's fine pointed bill. Sexes are similar, but winter birds and juveniles are less contrasted. In particular, the dark throat may be almost absent in young birds. The call is a fine ''ti-ti-ti'', and the song is similar to the dunnock's pleasant twittering. References black-throated accentor Bir ...
