Abstract: Current phylogenetic methods based on the multi-species coalescent model use information from the discordance among gene trees sampled independently throughout a genome to infer species trees and related parameters. However, with the growing availability of chromosome-scale sequence alignments we now have the power to analyze not only unlinked (uncorrelated) gene trees, but also linked (correlated) gene trees distributed spatially along the lengths of chromosomes. Here I introduce a new set of methods, termed the Multi-Species Sequentially Markov Coalescent (MS-SMC), to model the relationship between species trees and linked genealogical variation. I will also present applications of phylogenetic models to an empirical plant system, the genus Pedicularis, to model diversity and divergence at both geographic and genomic scales.
