THE TROPICAL FORESTS OF SOUTH AMERICA ARE MADE UP OF HETEROGENEOUS VEGETATION TYPES WITH UNIQUE ASSEMBLAGES OF TREE SPECIES COMPLEX VEGETATION DYNAMICS AND HISTORY AND HIGH BIODIVERSITY. THESE FORESTS ARE AN INTEGRAL PART OF THE GLOBAL CARBON AND HYDROLOGICAL CYCLES. THE INFLUENCE OF CLIMATE CHANGE ON THESE FORESTS IS JUST BEGINNING TO BE EXPLORED AND UNDERSTOOD. WITH NOTED INCREASES IN THE SEVERITY OF TROPICAL DROUGHTS THESE OFTEN RESILIENT FORESTS MAY WELL BE VULNERABLE AND WOULD EXHIBIT STRUCTURAL SPECIES AND CARBON STORAGE CHANGES. FIRE AND CHAINSAWS WILL CAUSE FASTER AND MORE CERTAIN FOREST LOSS IN AMAZONIA THAN THE NEXT CENTURY OF CLIMATE CHANGE. IN THE PAST AND TODAY HUMANS CAUSE ALMOST ALL FIRES IN AMAZONIA. THE REALIZATION THAT PRE-COLUMBIAN POPULATIONS IN AMAZONIA MAY HAVE NUMBERED C. 4-8 MILLION TRIGGERED A NEW FUSION OF ARCHAEOLOGY PALEOECOLOGY AND ECOLOGY INTO HUMAN ECOLOGY . A MAJOR QUESTION FOR HUMAN ECOLOGISTS IS: WERE THE PRE-COLUMBIAN IMPACTS ON AMAZONIAN FORESTS MORE OR LESS THAN THOSE SEEN TODAY?
