Abstract Detail

Phylogenetic Comparative Methods and Approaches in Plant Science

Sanderson, Michael [1].

Comparative biology on large phylogenetic trees.

The size of some published phylogenetic trees for plants now exceeds 10,000 species, providing unprecedented taxonomic coverage for comparative evolutionary and ecological analyses. In this talk I will examine some impacts of how these trees are reconstructed on downstream comparative analyses, such as divergence time and diversification rate estimation, ancestral state reconstruction and trait evolution modeling. In particular, because large fractions of missing data in multigene phylogenetic inference can introduce phylogenetic uncertainty that may degrade the reliability of comparative inferences, it is important to be able to characterize and ameliorate these impacts. Among other approaches discussed, the targeted deletion of subsets of taxa may improve not only phylogenetic inference but statistical inferences that rely on those trees.
