Orbiculus Leaf-nosed Bat
The orbiculus leaf-nosed bat (''Hipposideros orbiculus''), also known as the orbiculus roundleaf bat and small disc roundleaf bat, is a species of bat from the family Hipposideridae. The species has been found on the island of Sumatra in Indonesia and on peninsular Malaysia. Taxonomy The orbiculus leaf-nosed bat was described as a new species in 1999. The holotype had been collected in Abai Siat, which is southeast of Kota Bharu on the Indonesian island of Sumatra. It is cryptic species with the Ridley's leaf-nosed bat, though the two can be differentiated based on their echolocation characteristics: the frequencies of the two species' calls differ by 19 k Hz. Description Its forearm length is . Its tail is long and its ears are long. It echolocates at around 80 kHz. Range and status The orbiculus leaf-nosed bat has been documented in three areas: West Sumatra of Indonesia, near Rawang, Selangor of Malaysia, and Sungkai Wildlife Forest Reserve, which is also in Malaysia. ...

Hipposideridae
The Hipposideridae are a family of bats commonly known as the Old World leaf-nosed bats. While it has often been seen as a subfamily, Hipposiderinae, of the family Rhinolophidae, it is now more generally classified as its own family.Simmons, 2005, p. 365 Nevertheless, it is most closely related to Rhinolophidae within the suborder Yinpterochiroptera. Taxonomy The Hipposideridae contain 10 living genera and more than 70 species, mostly in the widespread genus ''Hipposideros''. In addition, several fossil genera are known; the oldest fossils attributed to the family are from the middle Eocene of Europe. In their 1997 ''Classification of Mammals'', Malcolm C. McKenna and Susan K. Bell proposed a division of Hipposideridae (called Rhinonycterinae in their work) into three tribes, one with two subtribes, but these tribes turned out to be non- monophyletic and have been abandoned. A different classification was proposed by Hand and Kirsch in 2003. In 2009, Petr Benda and Peter Vallo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rawang, Selangor
Rawang is a town and a mukim in Gombak District, Selangor, Malaysia, about 23 km northwest of city centre Kuala Lumpur. History Rawang was founded in the early-19th century and was one of Kuala Lumpur earliest satellite towns. During the initial tin mining growth of Kuala Lumpur, many tin mines were explored and opened north of Kuala Lumpur, starting initially at the Ulu Kelang area and gradually moving northwards past Selayang and towards Rawang. The earliest estimates of Rawang's founding date back to 1825. It was the second area in Selangor to be explored for tin mining. The tin mining industry in Rawang developed concurrently at around the same time as the larger tin mines Perak. During the Selangor Civil War of the 1860s and 1870s, Yap Ah Loy's gangs who were aligned with Tengku Kudin repelled Syed Mashor's troops away from Kuala Lumpur and pushed them further north. During the Battle of Rawang in 1871, Syed Mashor's followers and Chinese gangs loyal to him (led by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bats Of Southeast Asia
Bats are mammals of the order Chiroptera.''cheir'', "hand" and πτερόν''pteron'', "wing". With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is in length, across the wings and in mass. The largest bats are the flying foxes, with the giant golden-crowned flying fox, ''Acerodon jubatus'', reaching a weight of and having a wingspan of . The second largest order of mammals after rodents, bats comprise about 20% of all classified mammal species worldwide, with over 1,400 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the echolocating microbats. But more recent evidence has supported dividing the order into Yinpterochiroptera and Yangochiropter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1999
Mammals () are a group of vertebrate animals constituting the class (biology), class Mammalia (), characterized by the presence of mammary glands which in Female#Mammalian female, females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three ossicles, middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they Genetic divergence, diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant taxon, extant species of mammals have been described divided into 29 Order (biology), orders. The largest Order (biology), orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, Mole (animal), moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, pinniped, seals, and others).

Rainforest
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of lea ...

Lowland
Upland and lowland are conditional descriptions of a plain based on elevation above sea level. In studies of the ecology of freshwater rivers, habitats are classified as upland or lowland. Definitions Upland and lowland are portions of plain that are conditionally categorized by their elevation above the sea level. Lowlands are usually no higher than , while uplands are somewhere around to . On unusual occasions, certain lowlands such as the Caspian Depression lie below sea level. Upland habitats are cold, clear and rocky whose rivers are fast-flowing in mountainous areas; lowland habitats are warm with slow-flowing rivers found in relatively flat lowland areas, with water that is frequently colored by sediment and organic matter. These classifications overlap with the geological definitions of "upland" and "lowland". In geology an "upland" is generally considered to be land that is at a higher elevation than the alluvial plain or stream terrace, which are considered ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...
