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)
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)
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)
Amazon conservation policy working in Brazil, MSU-led study finds
Contrary to common belief, Brazil's policy of protecting portions of the Amazonian forest from development is capable of buffering the Amazon from climate change, according to a new study led by Michigan State University researchers. view more (2009-06-16)
Amazon outflow is found to power ocean capture of carbon dioxide
Nutrients washed out of the Amazon River are powering huge amounts of previously unexpected plant life far out to sea, thus trapping atmospheric carbon dioxide, according to a new study. view more (2008-07-24)
Amazon powers tropical ocean's carbon sink
Nutrients from the Amazon River spread well beyond the continental shelf and drive carbon capture in the deep ocean, according to the authors of a multi-year study. view more (2008-07-22)
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)
New monkey discovered in Brazil
The Wildlife Conservation Society (WCS) announced today the discovery of a new monkey in a remote region of the Amazon in Brazil. view more (2009-07-08)
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 watershed areas that the River Amazon springs forth,... view more... (2003-07-08)
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)
Workshop assesses interactions between climate, forests and land use in the Amazon Basin
On February 25 and 26, over 50 scientists gathered for a two-day workshop in Manaus, Brazil, to discuss the current state of knowledge on the feedbacks between deforestation and climate in the Amazon and what research is required to avoid catastrophic change. view more (2008-03-13)
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)
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 Brazilian institutes are to follow part of his... view more...

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 additional major source. Many studies have been... view more... (1999-09-13)
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 study, Martin Persson, in collaboration with Christian... view more... (2004-05-28)
`Glowing` technique could detect river pollution
New technology used to analyse dissolved organic matter in river water could also help scientists detect and monitor pollution, according to a new research published in the journal Hydrological Processes (1). Dissolved organic matter is found in all river water, and can come from both a natural source such as the soil, as well as human sources... view more... (2002-10-07)
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)
The Amazon : wedding in white and black
What happens when two rivers of widely different character meet? In order to answer this question, hydrologists from IRD (Institut de recherché pour le développement) have examined the confluence of the Rivers Negro and Solim'΅es, in Brazil. These two large water courses join just downstream from Manaus to form the Amazon. Up to now,... view more... (2000-11-07)
World's most endangered gorilla fights back
In the wake of a study that documented for the first time the use of weaponry by Cross River gorillas to ward off threats by humans, the Wildlife Conservation Society announced today new field surveys to better protect this most endangered great ape. view more (2007-12-06)
