Amazonia rainforest fires: A lacustrine record of 7000 years
Although human influence dominates present-day Amazonian rainforest fires, old charcoal fragments, buried in the soils or in lacustrine sediments, confirm that fire has played a major role in the history of Amazonian forests. These fires may have influenced the present-day diversity and structure of...

Although human influence dominates present-day Amazonian rainforest fires, old charcoal fragments, buried in the soils or in lacustrine sediments, confirm that fire has played a major role in the history of Amazonian forests.

Detailed studies of Carajas lake sediments permit identification of these past fire events, through microscopic observations of small charcoal fragments. They also permit, through radiocarbon dating, a better definition of their timing and make it possible to relate them to past paleo-environmental and paleoclimatic conditions.
