Professor
Professor (commonly abbreviated as Prof.) is an Academy, academic rank at university, universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a "person who professes". Professors are usually experts in their field and teachers of the highest rank. In most systems of List of academic ranks, academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word "professor" is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well. This usage would be considered incorrect among other academic communities. However, the otherwise unqualified title "Professor" designated with a capital let ...

Convention On Biological Diversity
The Convention on Biological Diversity (CBD), known informally as the Biodiversity Convention, is a multilateral treaty. The Convention has three main goals: the conservation of biological diversity (or biodiversity); the sustainable use of its components; and the fair and equitable sharing of benefits arising from genetic resources. Its objective is to develop national strategies for the conservation and sustainable use of biological diversity, and it is often seen as the key document regarding sustainable development. The Convention was opened for signature at the Earth Summit in Rio de Janeiro on 5 June 1992 and entered into force on 29 December 1993. The United States is the only UN member state which has not ratified the Convention. It has two supplementary agreements, the Cartagena Protocol and Nagoya Protocol. The Cartagena Protocol on Biosafety to the Convention on Biological Diversity is an international treaty governing the movements of living modified organisms ...

Himalayan Thrush
The Himalayan thrush or Himalayan forest thrush (''Zoothera salimalii'') is a species of bird described in 2016 and separated out from the alpine thrush ''Zoothera mollissima'' with which they were formerly lumped. The species is separated on the basis of phylogenetic studies that suggest that the population diverged from the common ancestor at least 3 million years ago (estimates vary from 3-6 mya). The alpine thrush (''Zoothera mollissima'' in the restricted sense) breeds above the tree line whereas the Himalayan thrush breeds in forested habitats. The species breeds from Sikkim and Darjeeling in India and extends east into Tibet and further east into northwest Yunnan in China. The species differs in its song from that of the alpine thrush. The Himalayan thrush has a more musical call while that of the Alpine thrush is raspy and grating. A newly discovered Himalayan forest thrush bird was named after the birdman of India, Ornithologist Dr.Salim Ali. The name of the bird is "Zoot ...

Mekong Wagtail
The Mekong wagtail (''Motacilla samveasnae'') is a species of bird in the family Motacillidae. It was first described in 2001 and named in honour of the late Cambodian ornithologist Sam Veasna. It is a black and white bird, similar in appearance to the African pied wagtail, although their ranges do not overlap. Its facial features and distinctive voice distinguish it from other black and white wagtails in southeastern Asia. The Mekong wagtail is found in the Mekong valley of Cambodia and Laos, and is a non-breeding visitor to Thailand and Vietnam. Its typical habitat is rocky areas beside fast-flowing stretches of river where seasonal flooding occurs. Although tolerant of humans, it is threatened by large scale alterations to its habitat such as inundation of riverine habitat following damming of the river. Description The Mekong wagtail most closely resembles African pied wagtail ''M. aguimp'', although two species ranges are far apart. It differs from ''M. agiump'' in sever ...

Sichuan Bush Warbler
The Sichuan bush warbler (''Locustella chengi'') lives primarily in the thick brush and on tea plantations in five mountainous provinces of central China. It is a relatively small bird with a weight of 10 grams and an average length of 13 cm. Unlike its congener the russet bush warbler, which is found in the same mountains and also in the Himalayas, Vietnam, the Philippines, and Indonesia, the Sichuan bush warbler prefers elevations below 7,500 feet. The two species shared a common ancestor about 850,000 years ago. They are distinguished by plumage and sonogram terminology – their songs. ''Locustella chengi'' emits a long buzz, followed by a shorter click, often repeated in series, and the song is in a lower frequency than its genetic cousin. The name honors Cheng Tso-hsin Tso-hsin Cheng (郑作新 also transcribed as Zheng Zuoxin) (18 November 1906 – 27 June 1998) was a Chinese ornithologist known for his seminal work on the birds of China and mentoring a generation ...

Alström's Warbler
Alström's warbler (''Phylloscopus soror''), or the plain-tailed warbler, is a species of Old World warbler in the family Phylloscopidae. It was first described in 1999. It breeds only in China and winters as far as Thailand, Laos, Cambodia and Vietnam. Its natural habitat is temperate forests. Habitat and migration Alström's warbler often forages in a low, dense growth of forests. This bird is known to eat insects and catch prey during short flights. The bird is not currently globally threatened. This bird has a very large range and does not approach the potential of being a vulnerable species. The warbler typically breeds in warmer, temperate areas. These areas are found within evergreen broadleaf forest zones and lush undergrowth in mature forests. It has a scattered breeding range across central and eastern China. The warbler tends to breed in bushes and small trees of low to moderate height, in recently cleared areas. This bird is a migratory species. It migrates durin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone Leaf Warbler
The limestone leaf warbler (''Phylloscopus calciatilis'') is a species of warbler in the family Phylloscopidae. When this species was first seen, beginning in 1994, it was mistaken for the similar sulphur-breasted warbler. It is smaller than the sulphur-breasted warbler, and has more rounded wings. The plumage is almost identical, with comparisons showing only a slightly colder yellow below and a greyer tinge above. Although smaller, the bill is proportionally larger than that of the sulphur-breasted warbler. Accurate measurements are not available; the holotype has a wing length of ; the paratype a tail length of and a bill length of . The species is known to occur in northern Vietnam and Laos, and potentially also occurs in southern China as well. The species name, ''calciatilis'', means "dwelling on limestone", which along with its common name is a reference to its natural habitat, which is broadleaved evergreen and semi-evergreen forest growing around limestone karst mountain ...

Emei Leaf Warbler
The Emei leaf warbler (''Phylloscopus emeiensis'') is a species of leaf warbler (family Phylloscopidae). It was formerly included in the "Old World warbler" assemblage. It breeds in China, and it is vagrant in Myanmar. Taxonomy and systematics The relationships are uncertain, but a study based on the mitochondrial cytochrome b and 12S and nuclear myoglobin intron 2 revealed no evidence for a close relationship to the morphologically similar Blyth's leaf warbler ''P. reguloides'' complex. Description The Emei leaf warbler is a small passerine, measuring in length. Its crown is greyish-green, slightly darker at rear than in front, with a pale median crown-stripe that is poorly marked in front, and slightly but noticeably broader, paler and more distinct at rear. It has a prominent pale yellowish-tinged supercilium and a distinct dark eye-stripe; the rest of ear-coverts are paler, with faint dark mottling. Its upperparts are dull green, clearly paler than the sides of its crown ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Author Citation (zoology)
In zoological nomenclature, author citation refers to listing the person (or team) who first makes a scientific name of a taxon available. This is done in a scientific work while fulfilling the formal requirements under the International Code of Zoological Nomenclature ("the Code"). According to Article 51.1 of the Code, "the name of the author does not form part of the name of a taxon and its citation is optional, although customary and often advisable", however recommendation 51A suggests: "The original author and date of a name should be cited at least once in each work dealing with the taxon denoted by that name. This is especially important and has a unique character between homonyms and in identifying species-group names which are not in their native combinations". For the seek of information retrieval, the author citation and year appended to the scientific name, e.g. genus-species-author-year, genus-author-year, family-author-year, etc., is often considered a "de facto" uniqu ...
