Tràm Chim National Park
Tràm Chim National Park () is a national park in the Plain of Reeds in the Mekong Delta region of Vietnam. The park was created to restore a degraded wetland, in order to protect several rare birds, especially the sarus crane (''Grus'' ''antigone sharpii'')--a species listed on the IUCN Red List. It is also a designated wetland of international importance under the Ramsar Convention. Ecology In its natural state, the Plain of Reeds was a seasonal wetland, covered in shallow water for three to six months annually, with annual grass fires in the dry season. Vegetation is thought to have been dominated by ''Melaleuca cajuputi'' trees, grasses, and other grass-like species such as sedges and ''Eleocharis''. Human modification of the environment began in the 18th century, with rice cultivation. During the Vietnam War, the area was drained and vegetation burned for strategic reasons, which had the effect of drying out and oxidizing the acid sulfate soils, making them highly aci ...

Melaleuca Cajuputi
''Melaleuca cajuputi'', commonly known as cajuput or white samet is a plant in the myrtle family, Myrtaceae and is widespread in Australia, Southeast Asia, New Guinea and the Torres Strait islands. It is a medium to tall tree with papery bark, silvery new growth and white or greenish flower spikes. It has important uses as a source of cajuput oil. Description ''Melaleuca cajuputi'' is usually a medium to large tree, often growing to and sometimes to with grey, brownish or whitish papery bark. The new growth is silky-hairy, becoming glabrous as it matures. The leaves are arranged alternately long and wide, tapering at both ends. The flowers are white, cream or greenish-yellow mostly in dense spikes at the ends of the branches which continue to grow after flowering but also often in the axils of the upper leaves. The spikes contain 8 to 20 groups of flowers, each group with three flowers. The stamens are grouped in five bundles around the flower, each bundle containing 6 ...

Protected Areas Established In 1998
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servin ...

Geography Of Đồng Tháp Province
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Parks Of Vietnam
Many areas of Vietnam are under protection. While the national reserves cover small areas of scientific significance with restricted access, the national parks also cover wetlands of Ramsar designated areas and BirdLife International inscribed bird areas. The largest of the national parks initially covered were the Cúc Phương National Park, the Cát Tiên National Park, and the Côn Đảo National Park which to start with were forest areas cum reserves or prohibited areas. The objective for creating national parks was to allow access to the reserved areas as a part of ecotourism and cultural needs with full attention to the basic approach of conservation of natural environmental resources. The national parks and reserves, as per present status, (as reported by the National Parks of Vietnam) conforming to the topography of the country which cover terrestrial, deltas of rivers, and coastal zones are: Five national parks and four reserves in the Mekong Delta; two national parks ...

Oryza Rufipogon
''Oryza rufipogon'', known as brownbeard rice, wild rice, and red rice, is a member of the genus ''Oryza''. It is native to East, Southeast and South Asia. It has a close evolutionary relation to ''Oryza sativa'', the plant grown as a major rice food crop throughout the world. Both have an AA genome. ''Oryza glumaepatula'' is a related species according to molecular biology approaches. It used to be considered a synonym referring to the South American race of ''O. rufipogon''. Invasive species ''Oryza rufipogon'' is an invasive species and listed as a 'noxious weed' by the United States, and also listed as a noxious weed in Alabama, California, Florida, Massachusetts, Minnesota, North Carolina, Oregon, South Carolina, and Vermont. According to the NAPPO (North American Plant Protection Organization), ''O. rufipogon'' blends in with cultivated ''O. sativa'' so well that it cannot be detected. In this position it competes with the cultivated rice and uses valuable fertilizer an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Giant Barb
The giant barb, Siamese giant carp, or simply Siamese carp (''Catlocarpio siamensis'') ( km, ត្រីគល់រាំង, ; th, กระโห้, , , or , , ; Vietnamese: ''cá Hô''), is the largest species of cyprinid in the world. These migratory fish are found only in the Mae Klong, Mekong, and Chao Phraya River basins in Indochina. Populations have declined drastically due to habitat loss and overfishing, and the giant barb is now considered critically endangered. Distribution and habitat Giant barbs are usually seen in large pools along the edges of large rivers, but seasonally enter smaller canals, floodplains, and flooded forests. Young barbs are usually found in smaller tributaries and swamps, but can acclimate to living in ponds, canals, and swamps. The fish generally live in pairs. These are migratory fish, swimming to favorable areas for feeding and breeding in different parts of the year. These slow-moving fish subsist on algae, phytoplankton, and fruit ...

Bengal Florican
The Bengal florican (''Houbaropsis bengalensis''), also called the Bengal bustard, is a bustard species native to the Indian subcontinent, Cambodia, and Vietnam. It is listed as Critically Endangered on the IUCN Red List because fewer than 1,000 individuals were estimated to be alive as of 2017. It is the only member of the genus ''Houbaropsis''. Description The male Bengal florican has a black plumage from the head and neck to underparts. Its head carries a long lanky crest, and the neck has elongated display plumes. The upperside is buff with fine black vermiculations and black arrowhead markings, and there is a conspicuous large white patch from the wing coverts to the remiges. In flight, the male's wings appear entirely white except for the dark primary remiges. The feet and legs are yellow, the bill and irides are dark. The female is buff-brown similar to the males' back with a dark brown crown and narrow dark streaks down the side of the neck. Her wing coverts are light ...

Acid Sulfate Soil
Acid sulfate soils are naturally occurring soils, sediments or organic substrates (e.g. peat) that are formed under waterlogged conditions. These soils contain iron sulfide minerals (predominantly as the mineral pyrite) and/or their oxidation products. In an undisturbed state below the water table, acid sulfate soils are benign. However, if the soils are drained, excavated or otherwise exposed to air, the sulfides react with oxygen to form sulfuric acid.Identification & Investigation of Acid Sulfate Soils (2006), Department of Environment, Western Australia. Retrieved froportal Release of this sulfuric acid from the soil can in turn release iron, aluminium, and other heavy metals and metalloids (particularly arsenic) within the soil. Once mobilized in this way, the acid and metals can create a variety of adverse impacts: killing vegetation, seeping into and acidifying groundwaterMosley LM, Palmer D, Leyden E, Fitzpatrick R, and Shand P (2014).

Redox
Redox (reduction–oxidation, , ) is a type of chemical reaction in which the oxidation states of substrate (chemistry), substrate change. Oxidation is the loss of Electron, electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. There are two classes of redox reactions: * ''Electron-transfer'' – Only one (usually) electron flows from the reducing agent to the oxidant. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * ''Atom transfer'' – An atom transfers from one substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously the oxidation state of oxygen decreases as it accepts electrons released by the iron. Although oxidation reactions are commonly associated with the formation of oxides, other chemical species can serve the same function. In hydrogen ...

Herbicidal Warfare
Herbicidal warfare is the use of substances primarily designed to destroy the plant-based ecosystem of an area. Although herbicidal warfare use chemical substances, its main purpose is to disrupt agricultural food production and/or to destroy plants which provide cover or concealment to the enemy, not to asphyxiate or poison humans and/or destroy human-made structures. Herbicidal warfare has been forbidden by the Environmental Modification Convention since 1978, which bans "any technique for changing the composition or structure of the Earth's biota". History Modern day herbicidal warfare resulted from military research discoveries of plant growth regulators in the Second World War, and is therefore a technological advance on the scorched earth practices by armies throughout history to deprive the enemy of food and cover. Work on military herbicides began in England in 1940, and by 1944, the United States joined in the effort. Even though herbicides are chemicals, due to their ...

Vietnam War
The Vietnam War (also known by #Names, other names) was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. The north was supported by the Soviet Union, China, and other communist states, while the south was United States in the Vietnam War, supported by the United States and other anti-communism, anti-communist Free World Military Forces, allies. The war is widely considered to be a Cold War-era proxy war. It lasted almost 20 years, with direct U.S. involvement ending in 1973. The conflict also spilled over into neighboring states, exacerbating the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist states by 1975. After the French 1954 Geneva Conference, military withdrawal from Indochina in 1954 – following their defeat in the First Indochina War – the Viet Minh to ...
