Poropuntius Bolovenensis
''Poropuntius bolovenensis'' is a species of ray-finned fish in the genus ''Poropuntius''. This species is endemic to the eastern half of the Boloven Plateau in southern Laos where its numbers are decreasing under heavy fishing pressure. However, the biggest threat to this species is the construction of dams which are likely to have a significant impact on this species. In addition the quality and area of its habitat is declining due to conversion for agriculture. The IUCN 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 natu ... assess ''P. bolovensis'' as Endangered. This species occurs in clear, rocky streams at altitudes of 800–1,200 m above sea level where it feeds mainly on insects. It does not thrive in reservoirs. It is not a true migrant but it does make local movements. It is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Poropuntius
''Poropuntius'' is a genus of cyprinid fish found mainly in freshwater habitats of Southeast Asia and Yunnan in China, but ''P. burtoni'' is from South Asia. Several species have highly restricted ranges and are threatened, and a single ''P. speleops'' is a cavefish.Romero, A., editor (2001). The Biology of Hypogean Fishes, p. 18. Developments in Environmental Biology of Fishes. Species There are currently 38 recognized species in this genus: * '' Poropuntius alloiopleurus'' ( Vaillant, 1893) * '' Poropuntius angustus'' Kottelat, 2000 * '' Poropuntius bantamensis'' (Rendahl ( de), 1920) * '' Poropuntius bolovenensis'' T.

Boloven Plateau
The Bolaven Plateau is an elevated region in southern Laos. Most of the plateau is located within Champasak Province of Laos, though the edges of the plateau are also located in Salavan, Sekong and Attapeu Provinces. It is located between the Annamite Mountain Range, along which runs Laos' eastern border with Vietnam, and the Mekong River to the west, at about . The plateau's elevation ranges approximately from above sea level. The plateau is crossed by several rivers and has many scenic waterfalls. The name Bolaven makes reference to the Laven ethnic group which has historically dominated the region. However, domestic migrations by the Lao ethnic group (which comprises approximately 50 to 60 percent of the population of Laos) has resulted in widespread interethnic marriage, thus modifying the ethnic composition of the region. Historical significance The Bolaven Plateau has had an important role in the greater history of Laos. The three most significant historical period ...

IUCN
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
