Abstract

Tropical tree biodiversity motivates an extremely large amount of research and some of the most passionate debates in ecology and evolution. Research into tropical tree biodiversity generally has been very biased towards one axis of biodiversity-species diversity. Less work has focused on the functional diversity of tropical trees and I argue that this has greatly limited our ability to not only understand the species diversity in tropical tree assemblages, but their distributions through space and time. Increasingly plant ecologists have turned to measuring plant functional traits to estimate functional diversity and to uncover the ecological and evolutionary mechanisms underlying the distribution and dynamics of tropical trees. Here I review much of the recent work on functional traits in tropical tree community ecology. I will highlight what I believe are the most important findings and which research directions are not likely to progress in the future. I also argue that functionally based investigations of tropical trees are likely to be revolutionized in the coming years through the incorporation of functional genomic approaches. The paper ends with a discussion of three major research areas or areas in need of focus that could lead to rapid advances in functionally based investigations of tropical trees.
