The Amazon Rainforest (Brazilian Portuguese: "Floresta Amazônica" or "Amazônia"; Spanish: "Selva Amazónica" or "Amazonía") is a moist broadleaf forest in the Amazon Basin of South America. The area, also known as Amazonia, the Amazon jungle, or the Amazon Basin, encompasses seven million square kilometers (1.7 billion acres), though the forest itself occupies some 5.5 million square kilometers (1.4 billion acres), located within nine nations: Brazil (with 60 percent of the rainforest), Peru (with 13 percent of the rainforest, second after Brazil), Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname, and French Guiana. States or departments in four nations bear the name Amazonas after it. The Amazon represents over half of the planet's remaining rainforests and comprises the largest and most species-rich tract of tropical rainforest in the world.

Etymology

The name "Amazon" is said to arise from a war which Francisco de Orellana had with a tribe of Tapuyas and other tribes from South America where the women of the tribe fought alongside the men, as was the custom among the entire tribe (Orellana's descriptions may have been accurate, but a few historians speculate that Orellana could have been mistaking indigenous men wearing "grass skirts" for women). Orellana derived the name Amazonas from the ancient Amazons of Asia and Africa described by Herodotus and Diodorus in Greek legends.

Another etymology for the word suggests that it came originally from a native word "amazona" (Spanish spelling) or "amassona" (Portuguese spelling), meaning "destroyer (of) boats", in reference to the destructive nature of the root system possessed by some riparian plants.

History

The rainforest likely formed during the Eocene era, following the evolutionary appearance of angiosperm plants. It appeared following a global reduction of tropical temperatures when the Atlantic Ocean had widened sufficiently to provide a warm, moist climate to the Amazon basin. The rain forest has been in existence for at least 55 million years, and most of the region remained free of savanna-type biomes during that time period.cite book

Following the K/T event, the extinction of the dinosaurs and the wetter climate may have allowed the tropical rainforest to spread out across the continent. From 65–34 Mya, the rainforest extended as far south as 45°. Climate fluctuations during the last 34 million years have allowed savanna regions to expand into the tropics. During the Oligocene, for example, the rainforest spanned a relatively narrow band that lay mostly above latitude 15°N. It expanded again during the Middle Miocene, then retracted to a mostly inland formation at the last glacial maximum. [cite journal

During the mid-Eocene, it is believed that the drainage basin of the Amazon was split along the middle of the continent by the Purus Arch. Water on the eastern side flowed toward the Atlantic, while to the west water flowed toward the Pacific across the Amazonas Basin. As the Andes Mountains rose, however, a large basin was created that enclosed a lake; now known as the Solimões Basin. Within the last 5–10 million years, this accumulating water broke through the Purus Arch, joining the easterly flow toward the Atlantic. [cite journal

There is evidence that there have been significant changes in Amazon rainforest vegetation over the last 21,000 years through the last glaciation (LGM) and subsequent deglaciation. Analyses of sediment deposits from Amazon basin paleolakes and from the Amazon Fan indicate that rainfall in the basin during the LGM was lower than for the present, and this was almost certainly associated with reduced moist tropical vegetation cover in the basin.Colinvaux, P.A., De Oliveira, P.E. 2000. Palaeoecology and climate of the Amazon basin during the last glacial cycle. Wiley InterScience. ( [http://www3.interscience.wiley.com/cgi-bin/abstract/72508326/ABSTRACT abstract] )] There is debate, however, over how extensive this reduction was. Some scientists argue that the rainforest was reduced to small, isolated refugia separated by open forest and grassland;Van der Hammen, T., Hooghiemstra, H.. 2002. Neogene and Quaternary history of vegetation, climate, and plant diversity in Amazonia. Elsevier Science Ltd. ( [http://dx.doi.org/10.1016/S0277-3791(99)00024-4 abstract] )] other scientists argue that the rainforest remained largely intact but extending less far to the North, South, and East than is seen today.cite journal

The diversity of plant species is the highest on Earth with some experts estimating that one square kilometer may contain over 75,000 types of trees and 150,000 species of higher plants. One square kilometer of Amazon rainforest can contain about 90,790 tonnes of living plants. This constitutes the largest collection of living plants and animal species in the world. One in five of all the birds in the world live in the rainforests of the Amazon. To date, an estimated 438,000 species of plants of economic and social interest have been registered in the region with many more remaining to be discovered or catalogued. [cite web

The needs of soy farmers have been used to validate many of the controversial transportation projects that are currently developing in the Amazon. The first two highways successfully opened up the rain forest and led to increased settlement and deforestation. The mean annual deforestation rate from 2000 to 2005 (22,392 km² per year) was 18% higher than in the previous five years (19,018 km² per year).

Environmentalists are concerned about the loss of biodiversity which will result from destruction of the forest, and also about the release of the carbon contained within the vegetation, which could accelerate global warming.

One computer model of future climate change due to greenhouse gas emissions shows that the Amazon rainforest could become unsustainable under conditions of severely reduced rainfall and increased temperatures, leading to an almost complete loss of rainforest cover in the basin by 2100. [Cox, Betts, Jones, Spall and Totterdell. 2000. [http://www.nature.com/uidfinder/10.1038/35041539 "Acceleration of global warming due to carbon-cycle feedbacks in a coupled climate model"] .

"The Guardian".] However, simulations of Amazon basin climate change across many different models are not consistent in their estimation of any rainfall response, ranging from weak increases to strong decreases.Houghton, J.T. "et al". 2001. [http://www.grida.no/climate/ipcc_tar/wg1/384.htm Climate Change 2001: The Scientific Basis] . Intergovernmental Panel on Climate Change.] The result indicates that the rainforest could be threatened though the 21st century by climate change in addition to deforestation.

In 1989, environmentalist C.M. Peters and two colleagues have stated there is not only a biological incentive to protecting the rainforest, but also an economic one. One hectare in the Peruvian Amazon has been calculated to have a value of $6820 if intact forest is sustainably harvested for fruits, latex, and timber; $1000 if clear-cut for commercial timber (not sustainably harvested); or $148 if used as cattle pasture.cite journal

Meanwhile, the relationship between nonhuman primates in the subsistence and symbolism of indigenous lowland South American peoples has gained increased attention, as has ethno-biology and community-based conservation efforts.

From 2002 to 2006, the conserved land in the Amazon Rainforest has almost tripled and deforestation rates have dropped up to 60%. About convert|1000000|km2|acre have been put onto some sort of conservation, which adds up to a current amount of convert|1730000|km2|acre. [cite journal

Remote sensing

] The use of remote sensing for the conservation of the Amazon is also being used by the indigenous tribes of the basin to protect their tribal lands from commercial interests. Using handheld GPS devices and programs like Google Earth, members of the Trio Tribe, who live in the rainforests of southern Suriname, map out their ancestral lands to help strengthen their territorial claims. [Isaacson, Andy. 2007. With the Help of GPS, Amazonian Tribes Reclaim the Rain Forest. Wired 15.11: http://www.wired.com/science/planetearth/magazine/15-11/ps_amazon ] Currently, most tribes in the Amazon do not have clearly defined boundaries, which make their territories easy targets for commercial poaching of natural resources. Through the use of cheap mapping technology, the Trio Tribe hopes to protect its ancestral land.

In order to accurately map the biomass of the Amazon, and subsequent carbon related emissions, the classification of tree growth stages within different parts of the forest are crucial. In 2006 Tatiana Kuplich organized the trees of the Amazon into four categories: (1) mature forest, (2) regenerating forest [less than three years] , (3) regenerating forest [between three and five years of regrowth] , and (4) regenerating forest [eleven to eighteen years of continued development] .
