Chestnut-capped Laughingthrush
The chestnut-capped laughingthrush (''Pterorhinus mitratus''), also known as the spectacled laughingthrush, is a species of bird in the family Leiothrichidae. It is found in Sumatra (Indonesia) and the Thai-Malay Peninsula. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. The chestnut-hooded laughingthrush was previously considered a subspecies. The chestnut-capped laughingthrush was formerly placed in the genus ''Garrulax'' but following the publication of a comprehensive molecular phylogenetic study in 2018, it was moved to the resurrected genus ''Pterorhinus ''Pterorhinus'' is a genus of passerine birds in the laughingthrush family Leiothrichidae.

Salomon Müller
Salomon Müller (7 April 1804 – 29 December 1864) was a German natural history, naturalist. He was born in Heidelberg, and died in Freiburg im Breisgau. Müller was the son of a saddler in Heidelberg. Along with Heinrich Boie and Heinrich Christian Macklot, he was sent by Coenraad Jacob Temminck to collect specimens in the East Indies. Here, he worked as an assistant for the ''Natuurkundige Commissie'' (Commission for Natural Sciences), an organization that he eventually became a member of.Nationaal Herbarium Nederland (biography). Müller arrived in Jakarta, Batavia in 1826, then journeyed to New Guinea and Timor in 1828 aboard the ''Triton''. Beginning in October 1828, he remained at the port cit ...

Garrulax
''Garrulax'' is a genus of passerine birds in the laughingthrush family Leiothrichidae. Taxonomy The genus ''Garrulax'' was erected by the French naturalist René Lesson in 1831. The type species was designated in 1961 as the rufous-fronted laughingthrush (''Garrulax rufifrons''). The genus previously included more species. Following the publication of a comprehensive molecular phylogenetic study in 2018, ''Garrulax '' was split up and species were moved to the resurrected genera ''Ianthocincla'' and '' Pterorhinus''. ''Garrulax'' species are heavily traded as songbirds. A survey of eight bird markets in Indonesia, carried out in 2014–2015, found 615 laughingthrushes of nine species openly for sale. Much of the trade in these species in Indonesia is illegal and is pushing a number of these species towards extinction. The Sumatran Laughingthrush, for example, is in serious decline due to ongoing and uncontrolled illegal trade in bird markets on the islands of Java and Su ...

Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic units known as "taxa" (singular "taxon")." Taxonomy is different from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1835
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. B ...

Birds Of The Malay Peninsula
''The Birds of the Malay Peninsula'' is a major illustrated ornithological reference work conceived and started by Herbert Christopher Robinson. The full title is ''The Birds of the Malay Peninsula: a general account of the birds inhabiting the region from the isthmus of Kra to Singapore with the adjacent islands''. It comprises five substantial ( large octavo) hardbound volumes of text, with 125 plates (123 in colour) by Henrik Grönvold and 11 maps. It was published by H. F. and G. Witherby, London. The binding of the first four volumes was red buckram; the fifth was red cloth with a dust jacket. History Robinson served as Director of Museums in the Federated Malay States in the early 20th century. On his retirement in 1926 he started to write the first of the five volumes of the series, with financial support for publication coming from the government of the Federated Malay States. The aim was to provide a treatment of the birds that could appeal to both professionals and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pterorhinus
''Pterorhinus'' is a genus of passerine birds in the laughingthrush family Leiothrichidae. Taxonomy The genus was erected by the English zoologist Robert Swinhoe in 1868 with the plain laughingthrush (''Pterorhinus davidi'') as the type species. The name of the genus combines the Ancient Greek ''pteron'' meaning "feather" with ''rhinos'' meaning "nostrils". These species were at one time placed in ''Garrulax'' but following the publication of a molecular phylogenetic study in 2018, ''Garrulax'' was split up and some of the species were moved to the resurrected genus ''Pterorhinus''. At the same time, the four species previously placed in ''Babax'' were moved here. Species The genus contains 23 species: * Rufous-necked laughingthrush, ''Pterorhinus ruficollis'' * Chestnut-backed laughingthrush, ''Pterorhinus nuchalis'' * Black-throated laughingthrush, ''Pterorhinus chinensis'' * Chestnut-capped laughingthrush, ''Pterorhinus mitratus'' * Chestnut-hooded laughingthrush, ''Pterorhin ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree. History The theoretical ...

Chestnut-hooded Laughingthrush
The chestnut-hooded laughingthrush (''Pterorhinus treacheri'') is a species of bird in the laughingthrush family Leiothrichidae endemic to Borneo. Described by the British ornithologist Richard Bowdler Sharpe as a distinct species in 1879, it was subsequently considered a subspecies of the chestnut-capped laughingthrush until 2007, when it was again raised to species status by the ornithologists Nigel Collar and Craig Robson. It is long, with a chestnut brown head and chin, with grey feathering on the top of the head. The and the side of the neck are slaty-grey, with a long white wing patch. The throat, breast, and upper belly are dull yellowish-brown, with purer grey and a reddish-brown , lower belly, and thighs. It has a yellow half eye-ring behind and below the eye, while the tail has a blackish tip. Both sexes look similar, while juveniles are duller than adults. The species inhabits montane and hill forest, forest edge, disturbed vegetation, and cultivated areas in mou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Montane Forest
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 ...

Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in ...
