Dulit Partridge
The Dulit partridge (''Rhizothera dulitensis''), also known as Hose's partridge, has been considered a distinctive subspecies of the long-billed partridge, a bird in the Phasianidae, or pheasant, family. It is endemic to Borneo, where it appears to be separated altitudinally from the nominate subspecies, and is often considered now to be a full species, ''Rhizothera dulitensis''. It is little-known, rare, and has not been recorded since 1937.Orenstein et al. (2010). Description The partridge is 30 cm in length. Like the long-billed partridge, it is mainly rufous-buff in colour, with a lavender-grey breast-band, a long, black, curved bill and yellow legs. It differs from the long-billed partridge in that the grey breast band is twice as wide, and the underparts are whitish-buff rather than bright orange-buff.Smythies & Davison (1998). Distribution and habitat The partridge is confined to lower montane forest on the mountains of Borneo. It was first recorded from Mount Du ...

Rhizothera
''Rhizothera'' is a bird genus in the family Phasianidae, native to Malaysia and Indonesia. They are the only genus in the tribe Rhizotherini. Established by George Robert Gray in 1841, it contains the following species: * Long-billed partridge (''Rhizothera longirostris'') * Dulit partridge (''Rhizothera dulitensis'') The name ''Rhizothera'' is constructed of two Greek words: ''rhiza'', meaning "root" and ''thēras'', meaning "hunter". Although their taxonomic relationships were formerly a mystery, with some taxonomists placing them with the more basal genera such as ''Arborophila'' and ''Xenoperdix'' that were formerly classified within the paraphyletic "Perdicinae" (this basal group is now known as Rollulinae), more recent phylogenetic studies place them as the sister group to the tribe Phasianini, which contains many well-known and widespread genera such as ''Perdix'' and ''Phasianus The "typical" pheasant genus ''Phasianus'' in the family Phasianidae consists of two s ...

Habitat Destruction
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 ...

Alfred Hart Everett
Alfred Hart Everett (11 October 1848 – 18 June 1898) was a British civil servant and administrator in Borneo as well as being a naturalist and natural history collector. Career Everett was born on Norfolk Island to British parents: George, the doctor at the penal colony, from Wiltshire, and Anna-Maria, from Jersey. They left in 1851 to return to England via Tasmania, so he was educated in England. In 1869 he went to Sarawak in north-western Borneo in order to collect natural history specimens. After two years there he entered the service of the Kingdom of Sarawak, as a Resident in the Baram district, under the White Rajahs. In 1878 and 1879 he was engaged by the Royal Society and British Association to explore 'the Caves of Borneo' in search of the remains of ancient man. The explorations were made around Bau and Niah but were unsuccessful in their primary aim (although the orangutan jaw which later formed part of Piltdown Man may well have been one result). In 1885 he was a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geography Mount Murud at the elevation of 2,424 m, is the highest mountain in Sarawak, located at the boundary between Miri and Limbang Division, in the Kelabit Highlands. It is a white-yellowish sandstone mountain, formed during the Miocene Epoch, extends for 4 km long, running in the ENE-WSW direction. Mount Murud has two highest points, with one point higher than the other by only 15 m. History According to a local legend, there was once a ''penghulu'' (headman) named Baya Kalong who stayed near the present-day Mount Murud area. He had a beautiful daughter named Kelawing. Kelawing was later married to another young ''penghulu'' named Tingang who came from another longhouse. However, Tingang's younger brother named Lawi became jealous of his brother and beheaded Kelawing while the couple was walking ...

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] |

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] |
