Phylogeny

Working with colleagues at Yale University, the University of Arkansas, and Louisiana State University, we developed a well-sampled, time-calibrated molecular phylogeny for conifers that includes around around 90% of extant conifer species and was dated with 26 fossil calibration points. We have used this work to provide a phylogenetic framework for a wide variety of projects, including exploring correlated patterns of character evolution in relation to functional morphology, how breeding systems in conifers may influence the evolution of dispersal traits, how phylogeny influences conifer biogeography, and even testing for phylogenetic signal in conifer biochemistry and isotopic fractionation.
