Dear all, We are excited to announce the upcoming Physalia online course, "Phylogenetic Comparative Methods in R," taking place from May 12-16. This course will provide a comprehensive introduction to generating ultrametric phylogenies (chronograms/timetrees) and applying phylogenetic comparative methods to study trait evolution and lineage diversification. Course website: ( https://www.physalia-courses.org/courses-workshops/course44/ ) Designed for students, researchers, and professionals across various fields including systematics, paleontology, ecology, behavior, and physiology the course combines theoretical lectures with hands-on tutorials in R. Participants will work with published datasets and are encouraged to bring their own data for analysis. Throughout the course, participants will learn how to build time-calibrated phylogenies using Bayesian approaches in BEAST, explore different models of trait evolution for both continuous and discrete characters, and apply methods such as phylogenetic independent contrasts and ancestral state reconstruction. The course will also cover how to analyse lineage diversification over time, identify potential mass extinctions, and study historical biogeography using specialized tools like BioGeoBEARS. For the full list of our courses and workshops, please visit: ( https://www.physalia-courses.org/courses-workshops/course44/ ) If you have any questions, feel free to reach out.
