MERCURY POLLUTION IN BOLIVIAN RIVERS
Mercury contamination in rivers of the Amazon Basin is increasingly a cause for concern. The region's soils, naturally containing abundant heavy metals, are one source of this mercury. Gold mining, which is an increasing activity in the Amazon region since gold fever took hold in the 1970s, is the... view more (1999-09-13)

Amazon River reversed flow
Ask any South American dinosaur which way the Amazon River flows and she would have told you east-to-west, the opposite of today. That's the surprising conclusion of researchers studying ancient mineral grains buried in the Amazon Basin.   view more (2006-10-25)

Assessing the Amazon River's sensitivity to deforestation
Understanding how the Amazon River varies in time, what causes those variations, and how sensitive it will be to ongoing, and accelerating, deforestation is a focus of study for scientists at the Woods Hole Research Center.   view more (2005-06-21)

Study suggests past climate changes may have promoted the formation of new species in the Amazon
The results of a new study suggest that past climate changes and sea level fluctuations may have promoted the formation of new species in the Amazon region of South America.   view more (2008-07-23)

Scientists find new clues to explain Amazonian biodiversity
Ice age climate change and ancient flooding-but not barriers created by rivers-may have promoted the evolution of new insect species in the Amazon region of South America, a new study suggests.   view more (2008-07-23)

Why the Amazon rainforest is so rich in species
Tropical areas of south and central America such as the Amazon rainforest are home to some 7500 species of butterfly compared with only around 65 species in Britain.   view more (2005-12-06)

Discovery of an ancient civilization in the west of the Amazon Basin
The western part of the Amazon basin is covered by tropical rainforest, severely eroded in places. The area is still largely unknown to archaeologists. It covers the lower eastern flanks of the Andean cordillera and extends from the piedmont down to the Amazon plain. It is in these twisting... view more (2003-07-08)

Human settlements already existed in the Amazon Basin (Equador) 4000 years ago
An important discovery by IRD archaeologists in Equador reveals that, more than 4000 years ago, early Andean civilizations had become established in a tropical environment where they were not hitherto known to have existed. This finding pushes further back the presumed beginning of developed... view more (2003-07-04)

Amazon rainforest at risk from initiative to connect South American economies
An unprecedented development plan to link South America's economies through new transportation, energy and telecommunications projects could destroy much of the Amazon rainforest in coming decades, according to a new study by Conservation International (CI) scientist Tim Killeen.   view more (2007-10-02)

IGBP calls for better observation of Earth's "Achilles' heels"
Monitoring the most sensitive "hotspots" of the Earth is an important way of assessing the health of our planet and predicting our future, said IGBP (International Geosphere-Biosphere Programme) scientists speaking at the Earth Observation Summit in Washington last week. The summit was... view more (2003-08-06)

Congo River Basin : Geology And Soil Type Influence Drought Impact
The Congo drainage basin is situated in Central Africa. Its hydrological system straddles several countries (Congo and the Democratic Republic of Congo for the most part, but also Angola, Cameroon, the Central African Republic, Zambia and Tanzania, stretching through Lake Tanganyika). The River... view more (2002-01-03)

Extinction most likely for rare trees in the Amazon rainforest
Common tree species in the Amazon will survive even grim scenarios of deforestation and road-building, but rare trees could suffer extinction rates of up to 50 percent, predict Smithsonian scientists and colleagues in the Aug. 12 issue of the journal Proceedings of the National Academy of Science.    view more (2008-08-14)

Researchers discover trees in Amazon much older than assumed, raising questions on global climate impact of region
Trees in the Amazon tropical forests are old. Really old, in fact, which comes as a surprise to a team of American and Brazilian researchers studying tree growth in the world's largest tropical region.   view more (2005-12-14)

Amazon Basin sediment accumulation influenced by La Ni'帶
Enormous quantities of sediment are deposited in the flood-plains traversed by the Amazon and its tributaries in times of flooding. Scientists have hitherto considered the sedimentation rate to be generally constant with time. Research conducted jointly by the IRD, the Universities of Washington1... view more (2003-11-21)

Amazon rainforest greens up in the dry season
The Amazon rainforest puts on its biggest growth spurt during the dry season, according to new research.   view more (2006-03-21)

Amazon Basin sediment accumulation influenced by La Ni'帶
Continental-scale rivers can transport enormous sediment loads. In periods of flood, a proportion of these is deposited on flood-plains. In the Amazon Basin, crossed by the Earth's largest river, great volumes of such sequestered sediment accumulations occur. This is especially so in the Llanos,... view more (2003-10-10)

Outflow from World's Largest River - the Amazon - Powers Atlantic Ocean Carbon
Nutrients from the Amazon River's outflow spread well beyond the continental shelf and drive carbon cycling in the tropical ocean, say scientists who conducted a multi-year study. They will publish their results this week online in the journal Proceedings of the National Academy of Sciences (PNAS).   view more (2008-07-23)

Rio Napo Mission 2004 in the Amazonian regions of Ecuador and Peru , 15 October-1 November
In 1541, the Spanish conquistador Francisco de Orellana embarked on the River Napo in Ecuador. This began his venture to go down the Amazon and reach the Atlantic Ocean. Aiming to retrace his journey, research teams of about 20 scientists from the IRD and several Ecuadorian, Bolivian, Peruvian and... view more (2004-10-08)

Climate protocol may save Amazon region
If Brazil gets a climate protocol, like the Kyoto Protocol for the rich countries, it will be possible to create an incentive for the country to reduce the deforestation of the Amazon region. The Kyoto Protocol targets a reduction of emissions of carbon dioxide and greenhouse gases. In a new... view more (2004-05-28)

Satellites show Amazon parks, indigenous reserves stop forest clearing
In a paper recently published in Conservation Biology (2006, Vol 20, pages 65-73), an international team of scientists, led by Daniel Nepstad of the Woods Hole Research Center and the Instituto de Pesquisa Ambiental da Amazonia, use satellite data to demonstrate, for the first time, that rainforest... view more (2006-01-26)

Watching over the Amazon forest by remote sensing
Areas deforested in Brazil increased from 152 000 km_ in 1976 to 517 000 km_ in 1996. That figure is the equivalent of the surface area of France (1). Deforestation is a complex process and involves a host of changing and widely differing situations. The factors behind it are many and varied. They... view more (2003-04-29)

Large size crucial for Amazon forest reserves
An international research team has discovered that the size of Amazon forest reserves is yet more important than previously thought.   view more (2007-01-12)

Amazon corridors far too narrow, warn scientists
Protected forest strips buffering rivers and streams of the Amazon rainforest should be significantly wider than the current legal requirement, according to pioneering new research by scientists at the University of East Anglia (UEA).   view more (2008-02-19)

Report shows deforestation threatens Brazil's Pantanal
Deforestation from increased grazing and agriculture has destroyed 17 percent of the native vegetation in Brazil's Pantanal, considered the world's largest wetland.   view more (2006-01-11)

Conservation of freshwater fish biodiversity: a challenge for the countries of the South
Humans have regularly been introducing exotic species into natural environments in order to provide for their nutritional necessities or meet less indispensable purposes such as horticulture, fishing or hunting.   view more (2008-03-27)
