BSA Past-Presidentís Symposium: Computational Issues and Solutions for the Study of Plant Phylogeny

Large-scale phylogenies uncover large-scale evolutionary patterns.

The scale of phylogenetic analyses, through the incorporation of both large numbers of species and characters, is growing at increasing rates. This has been largely facilitated by new semi-automated and automated methods for large-scale dataset assembly, coupled with new algorithms allowing for the reconstruction of phylogenies containing thousands to tens of thousands of species. The result is the ability to construct extremely large molecular phylogenies. With these very large trees, interesting patterns in molecular evolution, diversification, and phenotypic evolution (including climate tolerance and other characters) have emerged. We will explore these patterns and examine how the larger scale helps to illuminate our understanding of how life history, specifically generation time, influences large-scale phylogenetic patterns in plants.
