Damming the Rivers of the Amazon Basin [PDF]
Nature, 2017 More than a hundred hydropower dams have already been built in the Amazon basin and numerous proposals for further dam constructions are under consideration. The accumulated negative environmental effects of existing dams and proposed dams, if constructed, will trigger massive hydrophysical and biotic disturbances that will affect the Amazon basin's ...

Silicate Rock Weathering and Atmospheric/Soil CO2 Uptake in the Amazon Basin Estimated From River Water Geochemistry: Seasonal and Spatial Variations [PDF]
Chemical Geology, 2003 Using the data of the CAMREX project (1982–1984) on the water geochemistry of the Amazon river and its main tributaries, it was possible to assess the silicate rock weathering processes and the associated consumption of atmospheric/soil CO2, taking into

Contrasting Regional Discharge Evolutions in the Amazon Basin (1974–2004)
Journal of Hydrology, 2009 Former hydrological studies in the Amazon Basin generally describe annual discharge variability on the main stem. However, the downstream Amazon River only represents the mean state of the Amazonian hydrological system.

Modelling conservation in the Amazon basin
Nature, 2006Expansion of the cattle and soy industries in the Amazon basin has increased deforestation rates and will soon push all-weather highways into the region's core. In the face of this growing pressure, a comprehensive conservation strategy for the Amazon basin should protect its watersheds, the full range of species and ecosystem diversity, and the ...

Whether Amazonia is a carbon-dioxide source or sink has a significant effect on estimates of the global carbon budget. On an annual basis, El Nino, and its influence on precipitation in the region, seems to be a controlling factor.

Ballast water: A threat to the Amazon Basin
Marine Pollution Bulletin, 2014Ballast water exchange (BWE) is the most efficient measure to control the invasion of exotic species from ships. This procedure is being used for merchant ships in national and international voyages. The ballast water (BW) salinity is the main parameter to evaluate the efficacy of the mid-ocean ballast water exchange.

The Amazon Basin lies across the equator, so the climate is established by the motion of the equatorial low pressure region. The result is a very rainy wet season and a very dry dry season with two transitions. The wet season is characterized by short periods of rain several times each day, with time distribution of rainfall similar to that expected ...

Introduction Since the arrival of human beings about 12 000 years ago, wetlands have been favorite colonization areas because of their rich food resources. On Marajó Island at the mouth of the Amazon River and in its lower course, Amerindians built large chiefdoms on elevated places that provided protection against flooding (Roosevelt 1999).

Forest Biological Resources in the Amazon Basin
2004The Amazon region holds the world’s largest area of tropical rain forest which was settled by the first humans during the Late Pleistocene. A strong anthropogenic impact began in the 1960s when large areas of the tropical forest were cleared. To protect this ecosystem, sustainable utilization of its biological resources is urgently needed.

Beriberi is, as yet, a very common disease in the Brazilian portion of the Amazon Basin, and that means nearly the whole of the greatest river basin in the world. The view of some foreign physicians in regard to this disease in Brazil is that perhaps beriberi here may be different from that met in other portions of the globe. After having seen beriberi
