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)
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 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)
Scientists discover Amazon river is 11 million years old
Researchers at the University of Liverpool have discovered that the Amazon river, and its transcontinental drainage, is around 11 million years old and took its present shape about 2.4 million years ago. view more (2009-07-29)
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 watershed areas that the River Amazon springs forth,... 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 agricultural societies in the western Amazon Basin. It... view more... (2003-07-04)
U.N. Climate Change Conference considers ancient soil replenishment technique in battle against global warming
Former inhabitants of the Amazon Basin enriched their fields with charred organic materials-biochar-and transformed one of the earth's most infertile soils into one of the most productive. view more (2008-12-18)
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 attended by officials from more than 30 countries... 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 Congo, the second longest African river after the... 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)
MESSENGER discovers an unusual impact basin on Mercury
A previously unknown, large impact basin has been discovered by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft during its second flyby of Mercury in October 2008. view more (2009-05-01)
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 and California2 and the Bolivian National... 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, the Bolivian lowland flood-plains which stretch from... view more... (2003-10-10)
