Chinese Barbet
The Chinese barbet (''Psilopogon faber'') is a bird in the family Megalaimidae. The species was first described by Robert Swinhoe in 1870. It is endemic to southern China. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is threatened by habitat loss. It was formerly considered a subspecies of the black-browed barbet The black-browed barbet (''Psilopogon oorti'') is an Asian barbet native to Peninsular Malaysia and Sumatra, where it inhabits foremost forests between altitude.

Robert Swinhoe
Robert Swinhoe FRS (1 September 1836 – 28 October 1877) was an English diplomat and naturalist who worked as a Consul in Formosa. He catalogued many Southeast Asian birds, and several, such as Swinhoe's pheasant, are named after him. Biography Swinhoe was born in Calcutta where his father, who came from a Northumberland family, was a lawyer. There is no clear record of the date of his arrival in England, but it is known he attended the University of London, and in 1854 joined the China consular corps. He was stationed to the remote port of Amoy, some 300 miles to the northeast of Hong Kong, in 1855. While at this port he not only mastered the Chinese language (both official Mandarin and the local Amoy dialect), but also initiated a detailed and authoritative understanding of the ornithology of eastern China. In March, 1856, Swinhoe made an "adventurous" visit to the camphor districts of northwestern Formosa on board a lorcha, a hybrid vessel utilizing a European hull an ...

Bird
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 ...

Megalaimidae
The Asian barbets are a family of bird species, the Megalaimidae, comprising two genera with 35 species native to the forests of the Indomalayan realm from Tibet to Indonesia. They were once clubbed with all barbets in the family Capitonidae but the Old World species have been found to be distinctive and are considered, along with the Lybiidae and Ramphastidae, as sister groups. In the past the species were placed in three genera, ''Caloramphus'', ''Megalaima'' and ''Psilopogon'', but studies show that ''Psilopogon'' to be nested within the clade of ''Megalaima''. Since members of this clade are better treated under a single genus, they have been moved to the genus ''Psilopogon'' which was described and erected earlier than ''Megalaima'' and is therefore chosen on the basis of taxonomic priority principles. Nearly all members of the family are now in the genus ''Psilopogon'', with the exception of those in ''Caloramphus'', which are thought to have genetically diverged from the ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

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] |
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 th ...

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 in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Black-browed Barbet
The black-browed barbet (''Psilopogon oorti'') is an Asian barbet native to Peninsular Malaysia and Sumatra, where it inhabits foremost forests between altitude. It is listed as Least Concern on the IUCN Red List because of its wide distribution and stable population. Taxonomy ''Bucco oortii'' was the scientific name proposed by Salomon Müller in 1835 who described a barbet specimen collected in Sumatra. It was placed in the genus ''Megalaima'' proposed by George Robert Gray in 1842 who suggested to use this name instead of ''Bucco''. Molecular phylogenetic research of Asian barbets revealed that ''Megalaima'' species form a clade, which also includes the fire-tufted barbet, the only species placed in the genus ''Psilopogon'' at the time. Barbets formerly placed in this genus were therefore reclassified in the genus ''Psilopogon''. Description The black-browed barbet is mostly green with a yellow blue-bordered throat. It has black streaks above the eyes and red patches above ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psilopogon
''Psilopogon'' is a genus of Old World barbets that used to include only a single species, the fire-tufted barbet (''P. pyrolophus''). Results of molecular phylogenetic analyses indicate that the genus is nested within an evolutionary branch consisting of Asian barbets that were formerly placed in the genus ''Megalaima'' proposed by George Robert Gray in 1841. Since ''Psilopogon'' was proposed by Salomon Müller already in 1835, this name takes priority. The name ''Psilopogon'' combines the Ancient Greek ''psilos'' meaning "bare" and ''pōgōn'' meaning "beard". Taxonomy The type species of ''Psilopogon'' is the fire-tufted barbet proposed by Salomon Müller in 1835, who described a male barbet collected in Sumatra. In the 19th and 20th centuries, about 19 generic names were proposed for Asian barbet species in collections of natural history museums, including ''Megalaima'' by George Robert Gray in 1849 and ''Mezobucco'' by George Ernest Shelley in 1889.
