Chambira Basin
The Chambira River is a major tributary of the Marañón River, and has been the traditional territory of the Urarina peoples for at least the past 350 years, if not longer. Located in the Amazon jungle of Peru, otherwise known as the Selva, the Chambira is a tropical waterway with many purposes. There is a huge diversity of plants and animals in this region, which creates a unique ecosystem around the river. Made up of "palm-swamps", the region takes its name from the Chambira palm. Until relatively recently, the Chambira Basin was not a major focus of mapping, either by the Spanish Empire or the Peruvian nation. No major geographical surveys of the Chambira Basin were mounted during the 19th century heyday of exploration, and as a result it remained largely uncharted until the discovery of hydrocarbons in the region in the 1970s. With the subsequent mobilization of indigenous peoples and government-backed neo-liberal legislation, the lands of the Chambira Basin have now been fully ...

Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & S ...

Urarina
The Urarina are an indigenous people of the Peruvian Amazon Basin ( Loreto) who inhabit the valleys of the Chambira, Urituyacu, and Corrientes Rivers. According to both archaeological and historical sources, they have resided in the Chambira Basin of contemporary northeastern Peru for centuries. The Urarina refer to themselves as ''Kachá'' (lit. "person"), while ethnologists know them by the ethnonym Urarina. The local vernacular term for the Urarina is ''Shimaku'', which is considered by the Urarina to be pejorative, as it is a Quechua term meaning "unreliable". The ethnonym "Urarina" may be from Quechua languages, Quechua--''uray'' meaning below, and ''rina'' referring to ''runa'', or ''people''. Urarina is rendered in Quechua as ''uray-runa'' or ''people from below'' or ''down stream people''. Society and culture Urarina society and culture have been given little attention in the burgeoning ethnographic literature of the region, and only sporadic references in the encyclopedi ...

Chambira Palm
''Astrocaryum chambira'', the chambira palm or chambira, is a large and spiny palm native to the Amazon Rainforest in Colombia, Ecuador, Peru, and Venezuela that is mostly known for its commercial value as a fiber crop. It can reach over 25 meters in height, and it is not uncommon for climbing trees to be planted nearby to make harvesting the fruit and leaves both easier and safer. Indigenous people use the fibers of young leaves to weave into products such as nets, hammocks, bags, and other fabric and textile products. In most places where this fiber is used, the sale of products woven from these fibers to tourists is a major source of income, though there is great geographic variation in abundance and income received for products made from these fibers. In addition to the fibers, it is believed that the fruit and liquid endosperm within the seeds can help with fever reduction.

Spanish Empire
The Spanish Empire ( es, link=no, Imperio español), also known as the Hispanic Monarchy ( es, link=no, Monarquía Hispánica) or the Catholic Monarchy ( es, link=no, Monarquía Católica) was a colonial empire governed by Spain and its predecessor states between 1492 and 1976. One of the largest empires in history, it was, in conjunction with the Portuguese Empire, the first to usher the European Age of Discovery and achieve a global scale, controlling vast portions of the Americas, territories in Western Europe], Africa, and various islands in Spanish East Indies, Asia and Oceania. It was one of the most powerful empires of the early modern period, becoming the first empire known as "the empire on which the sun never sets", and reached its maximum extent in the 18th century. An important element in the formation of Spain's empire was the dynastic union between Isabella I of Castile and Ferdinand II of Aragon in 1469, known as the Catholic Monarchs, which in ...

Hydrocarbons
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons are generally colourless and hydrophobic, and their odors are usually weak or exemplified by the odors of gasoline and lighter fluid. They occur in a diverse range of molecular structures and phases: they can be gases (such as methane and propane), liquids (such as hexane and benzene), low melting solids (such as paraffin wax and naphthalene) or polymers (such as polyethylene and polystyrene). In the fossil fuel industries, ''hydrocarbon'' refers to the naturally occurring petroleum, natural gas and coal, and to their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers. Most anthropogenic (human-generated) emissions of greenhouse gases are carb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barrels
A barrel or cask is a hollow cylindrical container with a bulging center, longer than it is wide. They are traditionally made of wooden staves and bound by wooden or metal hoops. The word vat is often used for large containers for liquids, usually alcoholic beverages; a small barrel or cask is known as a keg. Modern wooden barrels for wine-making are made of French common oak (''Quercus robur''), white oak ('' Quercus petraea''), American white oak (''Quercus alba''), more exotic is Mizunara Oak all typically have standard sizes: Recently Oregon Oak ( Quercus Garryana) has been used. *"Bordeaux type" , *"Burgundy type" and *"Cognac type" . Modern barrels and casks can also be made of aluminum, stainless steel, and different types of plastic, such as HDPE. Someone who makes barrels is called a "barrel maker" or cooper (coopers also make buckets, vats, tubs, butter churns, hogsheads, firkins, kegs, kilderkins, tierces, rundlets, puncheons, pipes, tuns, butts, p ...

Heavy Metals
upright=1.2, Crystals of osmium, a heavy metal nearly twice as dense as lead">lead.html" ;"title="osmium, a heavy metal nearly twice as dense as lead">osmium, a heavy metal nearly twice as dense as lead Heavy metals are generally defined as metals with relatively high density, densities, atomic weights, or atomic numbers. The criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic number, while a chemist would likely be more concerned with chemical property, chemical behaviour. More specific definitions have been published, but none of these have been widely accepted. The definitions surveyed in this article encompass up to 96 out of the 118 known chemical elements; only mercury, lead and bismuth meet all of them.

Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Ecosystem
An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. ...
