Green Broadbill
The green broadbill (''Calyptomena viridis'') also known as the lesser green broadbill is a small bird in the family Calyptomenidae. It was formerly classified in the family Eurylaimidae, a group of closely related birds that share the name "broadbill". Taxonomy There are three subspecies recognized: * ''C. v. viridis'' Raffles, 1822 - the Malay Peninsula, extirpated from Singapore * ''C. v. gloriosa'' Deignan, 1947 - Sumatra, Borneo, Nias, the Lingga Islands, and the Natuna Islands * ''C. v. siberu'' Chasen & Kloss, 1926 - Mentawai Islands Prior to revisions by the International Ornithological Congress in 2022, the mainland subspecies went by the name ''caudacuta'', while ''viridis'' referred to the Greater Sundaic subspecies. Based on several previous studies finding problems with this nomenclature, the International Ornithological Congress replaced ''caudacuta'' with ''viridis'', while ''gloriosa'' replaced the former ''viridis''.

Thomas Stamford Raffles
Sir Thomas Stamford Bingley Raffles (5 July 1781 – 5 July 1826) was a British statesman who served as the Lieutenant-Governor of the Dutch East Indies between 1811 and 1816, and Lieutenant-Governor of Bencoolen between 1818 and 1824. He is best known mainly for his founding of modern Singapore and the Straits Settlements also called Malaysia and Brunei. Raffles was heavily involved in the capture of the Indonesian island of Java from the Dutch during the Napoleonic Wars. The running of day-to-day operations on Singapore was mostly done by William Farquhar, but Raffles was the one who got all the credit. He also wrote ''The History of Java'' (1817). Early life Thomas Stamford Bingley Raffles was born on on board the ship ''Ann'', off the coast of Port Morant, Jamaica, to Captain Benjamin Raffles (1739, London – 23 November 1811, Deptford) and Anne Raffles (née Lyde) (1755 – 8 February 1824, London). Benjamin served as a ship master for various ships engaged in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of Malesia
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calyptomena
''Calyptomena'' is a genus of birds in the family Calyptomenidae. The name is a combination of two Greek words: ''kaluptos'' meaning "covered", and ''mēnē'', meaning "moon". Established by Thomas Stamford Raffles in 1822, the genus contains three species: Species All three species are primarily green, and all are found in Borneo. The larger two species, Hose's and Whitehead's, are endemic to the island, while the smaller green broadbill is also found in Sumatra and on the Malay peninsula The Malay Peninsula (Malay: ''Semenanjung Tanah Melayu'') is a peninsula in Mainland Southeast Asia. The landmass runs approximately north–south, and at its terminus, it is the southernmost point of the Asian continental mainland. The area ....

IUCN Red List
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 provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ficus
''Ficus'' ( or ) is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig (''F. carica'') is a temperate species native to southwest Asia and the Mediterranean region (from Afghanistan to Portugal), which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses. Description ''Ficus'' is a pantropical genus of trees, shrubs, and vines occupying a wide variety of ecological niches; most are evergreen, bu ...

Canopy (biology)
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, canopy also refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms ( epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Sometimes the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees. Shade trees normally have a dense canopy that blocks light from lower growing plants. Observation Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs susp ...

Bird Anatomy
Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight. Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly. The development of a beak has led to evolution of a specially adapted digestive system. Skeletal system Birds have many bones that are hollow ( pneumatized) with criss-crossing struts or trusses for structural strength. The number of hollow bones varies among species, though large gliding and soaring birds tend to have the most. Respiratory air sacs often form air pockets within the semi-hollow bones of the bird's skeleton. The bones of diving birds are often less hollow than those of non-diving species. Penguins, loons, and puffins are without pneumatized bones entirely. Flightless birds, such as ostriches and emus, have pneumatized femurs and, in the case of 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] |
Greater Sunda Islands
The Greater Sunda Islands (Indonesian and Malay: ''Kepulauan Sunda Besar'') are four tropical islands situated within Indonesian Archipelago, in the Pacific Ocean. The islands, Borneo, Java, Sulawesi and Sumatra, are internationally recognised for their ecological diversity and rich culture. Together with the Lesser Sunda Islands to their southeast, they comprise the archipelago known as the Sunda Islands. Mainly part of Indonesia, each island is diverse in its ethnicity, culture and biological attributes. The islands have a long and rich history which has shaped their cultural backgrounds. Sumatra Geography Sumatra is the second largest, most westerly oriented Indonesian island, and the sixth largest island globally. Spanning , Sumatra is home to human civilisations and tropical rainforests, which harbour a huge range of wildlife. Its close proximity to the Equator (1º S, 101º E) dictates its tropical climate, so that it is subject to the forces of climatic events El Niño ...
