While large-scale pre-Columbian human occupation and ecological disturbance have been demonstrated close to major Amazonian waterways, less is known of sites in terra firme settings. Palaeoecological analyses of two lake districts in central and western Amazonia reveal long histories of occupation and land use. At both locations, human activity was centred(More)
X-ray diffraction studies carried out on single crystals of the monomeric, viz. 5,6-dimethoxy-2H-furo[2,3-h][1]benzopyran-2-one, C(13)H(10)O(5), and dimeric, viz. 5,5',6,6'-tetramethoxy-3,3',4,4'-tetrahydro-2H,2'H-3,3':4,4'-bi(furo[2,3-h][1]benzopyran)-2,2'-dione, C(26)H(20)O(10), forms of pimpinellin have revealed that, following cyclodimerization, the(More)
The main goal of this study was to reconstruct the Late Pleistocene-Holocene floristic composition in an area of the northern Brazilian Amazonia, comparing the results with other Amazonian localities in order to discuss the factors that have influenced phytophysiognomic changes over this time period. The work in eastern Marajó Island at the mouth of the(More)
