TL;DR: It is found that the distributions of tree taxa are indeed nested along precipitation gradients in the western Neotropics, and the results suggest that the ‘dry tolerance’ hypothesis has broad applicability in the world's most species-rich forests.

TL;DR: In this article, the late Quaternary history of the Caqueta River area in Colombia, northwestern Amazonia, was described, based on observations of river bank sections, radiocarbon dates and palynological analyses of organic layers in floodplain and low terrace sediments.

TL;DR: The sequence of Late-glacial and Holocene alluvial sedimentation in the middle Caqueta River Basin of Colombian Amazonia is described, based on the study of the sediments and palynology of several river bank sections and on 30 radiocarbon dates as discussed by the authors.
