Rio Ouro Preto Extractive Reserve
The Rio Ouro Preto Extractive Reserve ( pt, Reserva Extrativista Rio Ouro Preto) is an extractive reserve in the state of Rondônia, Brazil. Created in 1990, it was one of the first such reserves in Brazil. The residents extract rubber, nuts and other products in the dry season and farm or work outside the reserve in the rainy season, when large areas are flooded. Houses are built on stilts to avoid flooding and discourage animals from entering. Location The Rio Ouro Preto Extractive Reserve is divided between the municipalities of Guajará-Mirim (73.45%) and Nova Mamoré (26.55%) in Rondônia. It has an area of . The BR-421 federal highway runs east from the town of Guajará-Mirim on the Bolivian border, and enters the north part of the reserve. The reserve occupies the basin of the Ouro Preto River between two parallel east-west ranges of hills. It extends westward along the course of the Ouro Preto to where it joins the Pacaás Novos River, which forms the western boundary o ...

Green Anaconda
The green anaconda (''Eunectes murinus''), also known as the giant Emerald anaconda, common anaconda, common water boa or sucuri, is a boa species found in South America. It is the heaviest and one of the longest known extant snake species. Like all boas, it is a non-venomous constrictor. The term "anaconda" often refers to this species, though the term could also apply to other members of the genus ''Eunectes''. Fossils of the snake date back to the Late Pleistocene in the Gruta do Urso locality. Etymology The green anaconda's specific name is derived from the Latin ', meaning 'of mice', for being thought to prey on mice. Description The green anaconda is the world's heaviest and one of the world's longest snakes, reaching a length of up to long. More typical mature specimens reportedly can range up to , with adult females, with a mean length of about , being generally much larger than the males, which average around . Weights are less well studied, though reportedly ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PRONAF
The agriculture of Brazil is historically one of the principal bases of Brazil's economy. While its initial focus was on sugarcane, Brazil eventually became the world's largest exporter of coffee, soybeans, beef, and crop-based ethanol. The success of agriculture during the Estado Novo (New State), with Getúlio Vargas, led to the expression, "Brazil, breadbasket of the world". As of 2009, Brazil had about of undeveloped fertile land – a territory larger than the combined area of France and Spain. According to a 2008 IBGE study, despite the world financial crisis, Brazil had record agricultural production, with growth of 9.1%, principally motivated by favorable weather. The production of grains in the year reached an unprecedented 145,400,000 tons. That record output employed an additional 4.8% in planted area, totalling 65,338,000 hectares and producing $148 billion Reals. The principal products were corn (13.1% growth) and soy (2.4% growth). The southern one-half to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protected Areas Of Rondônia
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 (botany), 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 Scale (anatomy), scales and hair offer further protection from the elements and from predators, with some animals having features such ...

Hevea Benthamiana
''Hevea benthamiana'' is a species of rubber tree in the genus ''Hevea'', belonging to the family Euphorbiaceae. A medium-sized deciduous tree growing to a height of about , it is native to the rainforests of northern Brazil, Colombia and Venezuela. Description ''H. benthamiana'' is a medium-sized deciduous tree growing to around , often with a narrow crown and a swollen, bottle-like trunk; these features seem to be a response to periodic flooding because they do not occur in cultivated trees. This tree is deciduous, shedding its old foliage before stubby "winter shoots" develop. This may be a response to the fungal leaf diseases that readily occur in the constantly humid environment. The leaves have three elliptical leaflets which have a golden-brown pubescence on the underside. The inflorescences have separate male and female flowers, the male flowers having seven to nine stamens in two irregular whorls. The seeds are rounded.

Hevea Brasiliensis
''Hevea brasiliensis'', the Pará rubber tree, ''sharinga'' tree, seringueira, or most commonly, rubber tree or rubber plant, is a flowering plant belonging to the spurge family Euphorbiaceae Euphorbiaceae, the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of a genus in the family. Most spurges, such as '' Euphorbia paralias'', are herbs, but some, ... originally native to the Amazon basin, but is now pantropical in distribution due to introductions. It is the most economically important member of the genus ''Hevea'' because the milky latex extracted from the tree is the primary source of natural rubber. Description ''H. brasiliensis'' is a tall deciduous tree growing to a height of up to in the wild, but cultivated trees are usually much smaller because drawing off the latex restricts the growth of the tree. The trunk is cylindrical and may have a swollen, bottle-shaped base. The bark is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Socratea Exorrhiza
''Socratea exorrhiza'', the walking palm or cashapona, is a Arecaceae, palm native to rainforests in tropical Central America, Central and South America. It can grow to 25 metres in height, with a stem diameter of up to 16 cm, but is more typically 15–20 m tall and 12 cm in diameter. It has unusual stilt roots, the function of which has been debated. Many species of epiphyte have been found growing on the palms. The palm is pollinated by beetles, and various organisms eat its seeds or seedlings. Function of stilt roots E. J. H. Corner in 1961 hypothesised that the unusual stilt roots of ''S. exorrhiza'' were an adaptation to allow the palm to grow in swampy areas of forest. No evidence exists that stilt roots are in fact an adaptation to flooding, and alternative functions for them have been suggested. John H. Bodley suggested in 1980 that they in fact allow the palm to "walk" away from the point of germination if another tree falls on the seedling and knocks it ...

Copaiba
Copaiba is a stimulant oleoresin obtained from the trunk of several pinnate-leaved South American leguminous trees (genus ''Copaifera''). The thick, transparent exudate varies in color from light gold to dark brown, depending on the ratio of resin to essential oil. Copaiba is used in making varnishes and lacquers. The balsam may be steam distilled to give ''copaiba oil'', a colorless to light yellow liquid with the characteristic odor of the balsam and an aromatic, slightly bitter, pungent taste. The oil consists primarily of sesquiterpene hydrocarbons; its main component is β-caryophyllene. The oil also contains significant amounts of α-bergamotene, α-copaene, and β-bisabolene. Copaiba is also a common name for several species of trees of the legume family native to Tropical Africa and North and South America. Uses Copaiba is particularly interesting as a source of biodiesel, because of the high yield of . The resin is tapped from standing trees, with an individual ...

Natural Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...

Maçaranduba
''Manilkara bidentata'' is a species of ''Manilkara'' native to a large area of northern South America, Central America and the Caribbean. Common names include bulletwood, balatá, ausubo, massaranduba, quinilla, and (ambiguously) " cow-tree". Description The balatá is a large tree, growing to tall. The leaves are alternate, elliptical, entire, and long. The flowers are white, and are produced at the beginning of the rainy season. The fruit is a yellow berry, in diameter, which is edible; it contains one (occasionally two) seed(s). Its latex is used industrially for products such as chicle. Uses The latex is extracted in the same manner in which sap is extracted from the rubber tree. It is then dried to form an inelastic rubber-like material. It is almost identical to gutta-percha (produced from a closely related southeast Asian tree), and is sometimes called ''gutta-balatá''. Balatá was often used in the production of high-quality golf balls, to use as the outer layer of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
