In Amazzonia. [40] After witnessing the negative effects of environmental degradation, sedimentation, navigation and flood control caused by the Three Gorges Dam in the Yangtze River,[41] scientists are worried that constructing more dams in the Amazon will harm its biodiversity in the same way by "blocking-fish spawning runs, reducing the flows of vital oil nutrients and clearing forests".

He accepted to change the purpose of the expedition to discover new lands in the name of the king of Spain, and the men built a larger boat in which to navigate downstream. [69], The Amazon and its tributaries are the main habitat of the giant otter (Pteronura brasiliensis). [80] The most important microbes in the Amazon River are Actinobacteria, Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria and Crenarchaeota. [51], The Amazon River and its tributaries are characterised by extensive forested areas that become flooded every rainy season. The Pará and the Amazon are connected by a series of river channels called furos near the town of Breves; between them lies Marajó, the world's largest combined river/sea island. The success of the venture called attention to the opportunities for economic exploitation of the Amazon, and a second company soon opened commerce on the Madeira, Purús, and Negro; a third established a line between Pará and Manaus, and a fourth found it profitable to navigate some of the smaller streams.

This tectonic movement is caused by the subduction of the Nazca Plate underneath the South American Plate. This created dark soil areas known as terra preta de índio ("Indian dark earth"). Contos continued downstream to the ocean and finished the first complete descent of the Amazon river from its newly identified source (finishing November 2012), a journey repeated by two groups after the news spread.[45]. Si crea quando le acque dell’Oceano atlantico fluiscono all’interno del fiume per effetto di una marea. Early human settlements were typically based on low-lying hills or mounds.

[35], However, in the 1970s the government took a new approach with the National Integration Programme. All the remaining villages, as far up as Tabatinga, on the Brazilian frontier of Peru, were relatively small. Recently, metagenomics has provided answers to what kind of microbes inhabit the river. Acquario biotopo rio delle amazzoni. For most of its course, the river flows through the Amazon Rainforest, where there are very few roads and cities. Small towns and villages are scattered across the forest, and because its vegetation is so dense, some remote areas are still unexplored. [44][10] According to an earlier article on the webpage of the National Geographic, the Amazon's length was calculated as 6,800 kilometres (4,200 mi) by Brazilian scientist. Read more about rio.

True cinnamon (Cinnamomum Verum) is not native to South America. The fresh water, being lighter, flows on top of the seawater, diluting the salinity and altering the colour of the ocean surface over an area up to 2,500,000 km2 (970,000 sq mi) in extent. Local trade along the river was carried on by the English successors to the Amazonas Company—the Amazon Steam Navigation Company—as well as numerous small steamboats, belonging to companies and firms engaged in the rubber trade, navigating the Negro, Madeira, Purús and many other tributaries,[30] such as the Marañón, to ports as distant as Nauta, Peru. It has a series of major tributaries in Colombia, Ecuador and Peru, some of which flow into the Marañón and Ucayali, and others directly into the Amazon proper.

The bull shark (Carcharhinus leucas) has been reported 4,000 kilometres (2,485 mi) up the Amazon River at Iquitos in Peru.[79]. In this journey, Orellana baptized some of the affluents of the Amazonas like Rio Negro, Napo and Jurua. Amazon alluvium deposit - auta Join Facebook to connect with Rio Delle Amazzoni and others you may know. However, De Orellana missed the confluence (probably with the Aguarico) where he was searching supplies for his men. Four centuries after the European discovery of the Amazon river, the total cultivated area in its basin was probably less than 65 square kilometres (25 sq mi), excluding the limited and crudely cultivated areas among the mountains at its extreme headwaters. p. 93. By the time he and his men reached another village, many of them were sick from hunger and eating "noxious plants", and near death. Portuguese explorer Pedro Teixeira was the first European to travel up the entire river. Freigegeben / keine Freigabe erforderlich.

There are over 3,000 species of fish currently recognised in the Amazon basin, with more being discovered every year. Then distances from Lago Junín to several potential source points in the uppermost Mantaro river were measured, which enabled them to determine that the Cordillera Rumi Cruz was the most distant source of water in the Mantaro basin (and therefore in the entire Amazon basin). The Trans-Amazonian Highway's three pioneering highways were completed within ten years but never fulfilled their promise. Alagado... - panoramio.jpg 3,888 × 2,592; 3 MB. However, only a few of its species are known to attack humans, most notably Pygocentrus nattereri, the red-bellied piranha.

After 170 kilometres (106 mi), the Coca River joined the Napo River (at a point now known as Puerto Francisco de Orellana); the party stopped for a few weeks to build a boat just upriver from this confluence. Because of habitat destruction and hunting, its population has dramatically decreased. [48], The quantity of water released by the Amazon to the Atlantic Ocean is enormous: up to 300,000 cubic metres per second (11,000,000 cu ft/s) in the rainy season, with an average of 209,000 cubic metres per second (7,400,000 cu ft/s) from 1973 to 1990. Scientists argue that by burning areas of the forest repetitiously, the indigenous people caused the soil to become richer in nutrients.

In 1560, another Spanish conquistador, Lope de Aguirre, may have made the second descent of the Amazon. They are best represented by the Marajoara culture. The drainage area of the Amazon basin above Óbidos city is about 5,000,000 square kilometres (1,900,000 sq mi), and, below, only about 1,000,000 square kilometres (390,000 sq mi) (around 20%), exclusive of the 1,400,000 square kilometres (540,000 sq mi) of the Tocantins basin. This was done through a combination of credit and fiscal incentives. [15], The Atlantic has sufficient wave and tidal energy to carry most of the Amazon's sediments out to sea, thus the Amazon does not form a true delta. From 1648 to 1652, Portuguese Brazilian bandeirante António Raposo Tavares led an expedition from São Paulo overland to the mouth of the Amazon, investigating many of its tributaries, including the Rio Negro, and covering a distance of over 10,000 km (6,214 mi). For centuries ships have reported fresh water near the Amazon's mouth yet well out of sight of land in what otherwise seemed to be the open ocean. 5,600 species are currently known, and approximately fifty new species are discovered each year.

In 1851 Iquitos had a population of 200, and by 1900 its population reached 20,000. To achieve this level of development, the indigenous inhabitants of the Amazon rainforest altered the forest's ecology by selective cultivation and the use of fire. Gradually, this inland sea became a massive swampy, freshwater lake and the marine inhabitants adapted to life in freshwater.

The Manaus Iranduba Bridge linking the cities of Manaus and Iranduba spans the Rio Negro, the second-largest tributary of the Amazon, just before their confluence. The most accurate measurement method was direct GPS measurement obtained by kayak descent of each of the rivers from their source points to their confluence (performed by Contos). [30] The low river banks are interrupted by only a few hills, and the river enters the enormous Amazon rainforest. Etymonline.Com. The plume generated by the river's discharge covers up to 1.3 million square kilometres and is responsible for muddy bottoms influencing a wide area of the tropical north Atlantic in terms of salinity, pH, light penetration, and sedimentation.[13]. During glacial periods, sea levels dropped and the great Amazon lake rapidly drained and became a river, which would eventually become the world's second largest, draining the most extensive area of rainforest on the planet. Its most remote sources are found on the inter-Andean plateau, just a short distance from the Pacific Ocean. [30] This was the first step in opening up the vast interior. [30], Thanks in part to the mercantile development associated with steamboat navigation coupled with the internationally driven demand for natural rubber, the Peruvian city of Iquitos became a thriving, cosmopolitan center of commerce. Historians are uncertain whether the river he descended was the Amazon or the Orinoco River, which runs more or less parallel to the Amazon further north.
