A Long Pollen Record from Lowland Amazonia: Forest and Cooling in Glacial Times
TL;DR: In this article, a continuous pollen history of more than 40,000 years was obtained from a lake in the lowland Amazon rain forest, and the data suggest that the western Amazon forest was not fragmented into refugia in glacial times and that the lowlands were not a source of dust.
Journal ArticleDOI
Amazonian and neotropical plant communities on glacial time-scales: The failure of the aridity and refuge hypotheses
TL;DR: In this article, the authors use pollen data to reconstruct the vegetation of the Amazon basin in oxygen isotope stages 3 and 2 of the last glaciation in order to measure how the plant populations responded to the global warming at the onset of the Holocene.
Journal ArticleDOI

TL;DR: In this article, the tropical South American LGM data were interpreted from pollen, geochemical, and δ18O (stable oxygen isotope) data from Brazil and selected surrounding areas and the available terrestrial data were consistent with the SST derived precipitation data for the tropical forests in Brazil and for Africa.
Journal ArticleDOI
Amazon plant diversity and climate through the Cenozoic
TL;DR: In this article, a review of the available pollen data for the Amazon lowlands is presented, showing no evidence for glacial age aridity other than marginal reductions in precipitation within forest cover.
Journal ArticleDOI
Orbital forcing signal in sediments of two Amazonianlakes
TL;DR: Paleolimnological data from two ancient lakes at 0° latitude in Amazonia indicate that past lake level changes reflect precessional variations in insolation over the last 170,000 years as discussed by the authors.
