Peruvian Amazon
Peruvian Amazonia (), informally known locally as the Peruvian jungle () or just the jungle (), is the area of the Amazon rainforest in Peru, east of the Andes and Peru's borders with Ecuador, Colombia, Brazil, and Bolivia. Peru has the second-largest portion of the Amazon rainforest after the Brazilian Amazon. Extension Most Peruvian territory is covered by dense forests on the east side of the Andes, yet only 5% of Peruvians live in this area. More than 60% of Peruvian territory is covered by the Amazon rainforest, more than in any other country. According to the Research Institute of the Peruvian Amazon (''Instituto de Investigaciones de la Amazonía Peruana'', IIAP), the spatial delineation of the Peruvian Amazon is as follows: * Ecological criteria: 782,880.55 km2 (60.91% of Peruvian territory and approximately 11.05% of the entire Amazon jungle). * Hydrographic criteria or basin criteria: (75.31% of Peruvian territory and approximately 16.13% of the whole Amazon b ...

7 - Itahuania - Août 2008
7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube (algebra), cube. As an early prime number in the series of positive integers, the number seven has symbolic associations in religion, mythology, superstition and philosophy. The seven classical planets resulted in seven being the number of days in a week. 7 is often considered lucky in Western culture and is often seen as highly symbolic. Evolution of the Arabic digit For early Brahmi numerals, 7 was written more or less in one stroke as a curve that looks like an uppercase vertically inverted (ᒉ). The western Arab peoples' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit more rectilinear. The eastern Arab peoples developed the digit from a form that looked something like 6 to one that looked like an uppercase V. Both modern Arab forms influenced the European form, a two-stroke form cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Manu River
The Manu is a river in southeastern Peru. It runs down the eastern slopes of the Andes Mountains into the Amazon Basin. It runs through what is now protected as the Manu National Park, a vast Biosphere Reserve, home to arguably the highest concentration of biodiversity on Earth. Few people live along its length. Much of the park is off-limits to all but permitted scientists and the indigenous groups of Amazonian Indians, mostly of the Machiguenga tribe. The Manu is a tributary to the 1,347 km long Madre de Dios River, which downriver joins the Madeira River, and ultimately the Amazon River. In the late 19th and early 20th centuries, this area of what was organized as the Madre de Dios region was exploited for the production of rubber during the rubber boom The Amazon rubber cycle or boom (, ; , ) was an important part of the socioeconomic history of Brazil and Amazonian regions of neighboring countries, being related to the commercialization of rubber and the genocide of ind ...

Madre De Dios River
The Madre de Dios River () is a river shared by Bolivia and Peru which is homonymous to the Peruvian region it runs through. On Bolivian territory, it receives the Beni River, close to the town of Riberalta, which later joins with the Mamore River to become the Madeira River after the confluence. The Madeira is a tributary to the Amazon River. The Madre de Dios is an important waterway for the department of Madre de Dios, particularly Puerto Maldonado, the largest town in the area, and the capital of the department. Mango farming and gold mining are among the many industries on its banks. Other important industries the Madre de Dios provides are selective logging and farming, both of which are serious environmental problems. Along the length of the river, there are several national parks and reserves, notably Tambopata-Candamo National Park, Manu National Park (also known as Manu Biosphere Reserve) and Bahuaja-Sonene National Park.
