Predictive models of primary tropical forest structure from geomorphometric variables based on SRTM in the Tapajo's region, Brazilian Amazon
(2016-04-01)
Surveying primary tropical forest over large regions is challenging. Indirect methods of relating terrain information or other external spatial datasets to forest biophysical parameters can provide forest structural maps ...

Elevated levels of selenium in the typical diet of Amazonian riverside populations
(ELSEVIER SCIENCE BV, 2010)
Selenium (Se) intake is generally from food, whose Se content depends on soil Se and plant accumulation. For humans, adequate Se intake is essential for several selenoenzymes. In the Lower Tapajos region of the Brazilian ...
Selenium and Mercury in the Brazilian Amazon: Opposing Influences on Age-Related Cataracts
(US DEPT HEALTH HUMAN SCIENCES PUBLIC HEALTH SCIENCE, 2010)
BACKGROUND: Age-related cataracts (ARCs) are an important cause of blindness in developing countries. Although antioxidants may be part of the body's defense to prevent ARC, environmental contaminants may contribute to ...
Linking the timing of disseminated granite-hosted gold-rich deposits to paleoproterozoic felsic magmatism at alta floresta gold province, Amazon Craton, Brazil: Insights from pyrite and molybdenite Re-Os geochronology
(2017-12-01)
The Alta Floresta gold province consists of Paleoproterozoic (2.0-1.75 Ga) plutonic-volcanic sequences that originated from successive magmatic arcs accreted to the central Amazon tectonic province in the southwestern ...
Tectonics and paleogeography along the Amazon river
(2001-09-22)
The main structural and geomorphological features along the Amazon River are closely associated with Mesozoic and Cenozoic tectonic events. The Mesozoic tectonic setting is characterised by the Amazonas and Marajó Basins, ...
