History and Geography of Neotropical Tree Diversity

Early botanical explorers invoked biogeographic history to explain the remarkable tree diversity of Neotropical forests. In this context, we review the history of Neotropical tree diversity over the past 100 million years, focusing on biomes with significant tree diversity. We evaluate hypotheses for rain forest origins, intercontinental disjunctions, and models of Neotropical tree diversification. To assess the impact of biotic interchange on...
