Nonetheless, a basin-wide description of both taxonomic and phylogenetic alpha and beta diversity at regional scales has never been achieved. We present a complete floristic analysis of white-sand forests across the Amazon basin including both taxonomic and phylogenetic diversity. We found strong regional differences in the signal of phylogenetic community structure with both overall and regional Net Relatedness Index and Nearest Taxon Index values found to be significantly positive leading to a pattern of phylogenetic clustering. Additionally, we found high taxonomic dissimilarity but low phylogenetic dissimilarity in pairwise community comparisons. These results suggest that recent diversification has played an important role in the assembly of white-sand forests causing geographic neo-endemism patterns at the regional scale. {\textcopyright} 2016 The Association for Tropical Biology and Conservation.", optnote="Cited By :3; Export Date: 12 February 2016", optnote="exported from refbase (http://php.ecofog.gf/refbase/show.php?record=660), last updated on Fri, 12 Feb 2016 09:50:11 -0300", opturl="http://www.scopus.com/inward/record.url?eid=2-s2.0-84956604749&partnerID=40&md5=59e4065c3195822e5fe2644fe3c61a2c" }
