Ha Long Roundleaf Bat
''Hipposideros alongensis'', known as the Ha Long leaf-nosed bat, is a species of bat in the family Hipposideridae. It is endemic to Vietnam. It is listed as a vulnerable species by the IUCN. Taxonomy The species was formerly known as a subspecies of '' H. turpis''. It is now formally described as a distinct species. There are two subspecies: * Bourret's leaf-nosed bat (''H. a. alongensis'') * Sung's leaf-nosed bat (''H. a. sungi'') Distribution and habitat The species is only found in the karst habitats of northeastern Vietnam, and is primarily a cave-dweller, although it is also known to be spotted in forests. It is found from an altitude of . Of the two subspecies, Bourret's leaf-nosed bat is found in the Cat Ba and Bai Tu Long national parks and Sung's leaf-nosed bat is found in the Cuc Phuong and Ba Be national parks and the Huu Lien and Na Hang nature reserves. Conservation In the most recent published assessment, the species is listed as a vulnerable s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Val ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cúc Phương National Park
Cúc Phương National Park ( vi, Vườn quốc gia Cúc Phương) is located in Ninh Bình Province, in Vietnam's Red River Delta. Cuc Phuong was Vietnam's first national park and is the country's largest nature reserve. The park is one of the most important sites for biodiversity in Vietnam. History In 1960 Cúc Phương was made into a forest reserve and in 1962 Cúc Phương National Park was consecrated by President Ho Chi Minh. Human habitation in Cúc Phương dates back long before the park’s creation, 7,000-12,000 years ago. Artifacts from that time have been found in numerous caves within the park, including human graves, stone axes, pointed bone spears, oyster shell knives, and tools for grinding. In 1789 the Quen Voi section of the park was the site of a major battle in the civil war between Nguyễn Huệ and Thăng Long. More recently, conflicts have emerged between the government and 2,500 Muong ethnic minority tribesmen who live, farm, and hunt in the par ...

Ba Bể National Park
Ba Bể National Park ( vi, Vườn Quốc Gia Ba Bể) is a reserve in Bắc Kạn Province, Northeast region of Vietnam, set up to protect a very murky lake (Ba Bể Lake) along with surrounding limestone and highland nevergreen forests. It is located about 240 kilometers northwest of the capital city Hanoi. Location Ba Bể National Park is located in Bắc Kạn Province, about 240 kilometers north of Hanoi, about 70 km northwest of the provincial capital Bắc Kạn, and about 14 km west of the town of Cho Ra. Ba Bể Lake Ba Bể Lake ( vi, Hồ Ba Bể, Ba Bể meaning "Three Lakes" in the local Tay language) is the largest natural fresh water lake, stretching about 8 kilometers in the north-south direction. The surface area of the lake fluctuates between 3 and 5 km2 between dry and wet season. Unlike many lakes in Karst limestone areas, Ba Bể Lake never falls dry. Its average depth varies between 17 and 23 meters, the maximum depth is 35 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulnerable Species
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are 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, 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 taxon is Vulnerable when it is not critically endangered or Endangered but ...

Mammals Described In 1942
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, 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, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...
