Resumen
Amazonian wetlands are subject to prolonged waterlogging, which is known to be a major determinant of local composition and species distributions. However, our understanding of which traits determine species distributions in Amazonian wetlands and how these traits evolved is still scant. Due to correspondence between species traits, the niche and biogeographic pattern, novel perspectives on wetland assembly processes might be gained by examining local assemblies within a biogeographic framework. Here, we consider a biogeographic framework to examine the response of woody plant assemblages to permanent waterlogging in seven lowland wetlands of peat substrate. We quantitatively examine the variability of biogeographic relations among co-existing species to show that many taxa in extreme wetlands are uncommon in surrounding forests, but rather have wider biogeographic affnities. We propose that a high diversity of biogeographic histories may provide ecologically differentiated taxa for the colonization of environmentally extreme habitats in Amazonia. © 2017 John Wiley & Sons Ltd.
