Cinnamomum Cambodianum
''Cinnamomum cambodianum'' ( km, ទេព្វិរូ, teppirou) is a non-scented species of cinnamon, native and endemic to Cambodia. Commonly referred to as Cambodia cinnamon, ''C. cambodianum'' is an evergreen tree with a large, dense crown, growing 15–25 metres tall. The straight, cylindrical bole can grow to 30–80 cm in diameter. Habitat and distribution ''Cinnamomum cambodianum'' is endemic to Cambodia and is plentiful on the upper slopes of the Cardamom Mountains, including the Elephant Mountains, in the southwest of Cambodia. There are disjunct populations in Ratanakiri and Kampong Thom, in the northeast of the country.see "Cambodia Tree Seed Project" This species of cinnamon grows in wet, dense, foothill forests from 600–700 m above sea level. When young, it is a shade-demanding tree and it grows well in deep soil. It usually grows in clusters of 5–10 trees in the primary of secondary forest, at altitudes below 1,500 m above sea level.

Cinnamon
Cinnamon is a spice obtained from the inner bark of several tree species from the genus '' Cinnamomum''. Cinnamon is used mainly as an aromatic condiment and flavouring additive in a wide variety of cuisines, sweet and savoury dishes, breakfast cereals, snack foods, bagels, teas, and traditional foods. The aroma and flavour of cinnamon derive from its essential oil and principal component, cinnamaldehyde, as well as numerous other constituents including eugenol. Cinnamon is the name for several species of trees and the commercial spice products that some of them produce. All are members of the genus ''Cinnamomum'' in the family Lauraceae. Only a few ''Cinnamomum'' species are grown commercially for spice. '' Cinnamomum verum'' (AKA ''C. zeylanicum''), known as "Ceylon cinnamon" after its origins in Sri Lanka (formerly Ceylon), is considered to be "true cinnamon", but most cinnamon in international commerce is derived from four other species, usually and more correctly ref ...

Menstruation
Menstruation (also known as a period, among other colloquial terms) is the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. The menstrual cycle is characterized by the rise and fall of hormones. Menstruation is triggered by falling progesterone levels and is a sign that pregnancy has not occurred. The first period, a point in time known as menarche, usually begins between the ages of 12 and 15. Menstruation starting as young as 8 years would still be considered normal. The average age of the first period is generally later in the developing world, and earlier in the developed world. The typical length of time between the first day of one period and the first day of the next is 21 to 45 days in young women. In adults, the range is between 21 and 31 days with the average being 28 days. Bleeding usually lasts around 2 to 7 days. Periods stop during pregnancy and typically do not resume during the initial months of bre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Cambodia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deforestation In Cambodia
Deforestation in Cambodia has increased in recent years. Cambodia is one of the world's most forest endowed countries, that was not historically widely deforested. However, massive deforestation for economic development threatens its forests and ecosystems. , the country has one of the highest rates of deforestation in the world. Deforestation has directly resulted from poorly managed commercial logging, fuel wood collection, agricultural invasion, and infrastructure and urban development. Indirect pressures include rapid population growth, inequalities in land tenure, lack of agriculture technology, and limited employment opportunities.Sin, Meng Srun. ''Forestry in Cambodia: The Dilemma of Development and Preservation.'' Phnom Penh: n.p., 2014. Print. The Cambodian government has played a large role in shaping the use of the country's forests. An unusually large area of Cambodia has been designated as protected areas and biodiversity corridors, over 38% (more than 7 million hec ...

Germplasm
Germplasm are living genetic resources such as seeds or tissues that are maintained for the purpose of animal and plant breeding, preservation, and other research uses. These resources may take the form of seed collections stored in seed banks, trees growing in nurseries, animal breeding lines maintained in animal breeding programs or gene banks, etc. Germplasm collections can range from collections of wild species to elite, domesticated breeding lines that have undergone extensive human selection. Germplasm collection is important for the maintenance of biological diversity and food security.

Illegal Logging
Illegal logging is the harvest, transportation, purchase or sale of timber in violation of laws. The harvesting procedure itself may be illegal, including using corruption, corrupt means to gain access to forests; extraction without permission, or from a protected area; the cutting down of protected species; or the extraction of timber in excess of agreed limits. Illegal logging is a driving force for a number of environmental issues such as deforestation, soil erosion and biodiversity loss which can drive larger scale environmental crisis such as climate change and other forms of Environmental degradation, environmental degradation. Illegality may also occur during transport, such as illegal processing and export (through smuggling, fraudulent declaration to customs); the tax avoidance, avoidance of taxes and other charges, and fraudulent certification. These acts are often referred to as "wood laundering". Illegal logging is driven by a number of economic forces, such as demand ...

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] |
TRAFFIC
Traffic comprises pedestrians, vehicles, ridden or herded animals, trains, and other conveyances that use public ways (roads) for travel and transportation. Traffic laws govern and regulate traffic, while rules of the road include traffic laws and informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections. Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, or signs. Traffic is often classified by type: heavy motor vehicle (e.g., car, truck), other vehicle (e.g., moped, bicycle), and pedestrian. Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of the road while others rely more on drivers' common sense and willingness to cooperate. Orga ...

Eugenol
Eugenol is an allyl chain-substituted guaiacol, a member of the allylbenzene class of chemical compounds. It is a colorless to pale yellow, aromatic oily liquid extracted from certain essential oils especially from clove, nutmeg, cinnamon, basil and bay leaf. It is present in concentrations of 80–90% in clove bud oil and at 82–88% in clove leaf oil. Eugenol has a pleasant, spicy, clove-like scent. The name is derived from ''Eugenia caryophyllata'', the former Linnean nomenclature term for cloves. The currently accepted name is ''Syzygium aromaticum''. Biosynthesis The biosynthesis of eugenol begins with the amino acid tyrosine. L-tyrosine is converted to ''p''-coumaric acid by the enzyme tyrosine ammonia lyase (TAL). From here, ''p''-coumaric acid is converted to caffeic acid by ''p''-coumarate 3-hydroxylase using oxygen and NADPH. ''S''-Adenosyl methionine (SAM) is then used to methylate caffeic acid, forming ferulic acid, which is in turn converted to feruloyl- C ...

Cinnamaldehyde
Cinnamaldehyde is an organic compound with the formula(C9H8O) C6H5CH=CHCHO. Occurring naturally as predominantly the ''trans'' (''E'') isomer, it gives cinnamon its flavor and odor. It is a phenylpropanoid that is naturally synthesized by the shikimate pathway. This pale yellow, viscous liquid occurs in the bark of cinnamon trees and other species of the genus '' Cinnamomum''. The essential oil of cinnamon bark is about 90% cinnamaldehyde. Cinnamaldehyde decomposes to styrene because of oxidation as a result of bad storage or transport conditions. Styrene especially forms in high humidity and high temperatures. This is the reason why cinnamon contains small amounts of styrene. Structure and synthesis Cinnamaldehyde was isolated from cinnamon essential oil in 1834 by Jean-Baptiste Dumas and Eugène-Melchior Péligot and synthesized in the laboratory by the Italian chemist Luigi Chiozza in 1854. The natural product is ''trans''-cinnamaldehyde. The molecule consists of a benzene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
