Species trees need to be dated for many downstream applications. Some scalable molecular dating methods take a phylogenetic tree with branch lengths in substitution units, as well as a set of calibrations, as input and convert the branch le...

One of the most transformative advances in molecular systematics over the past several decades has been our understanding of how population processes like incomplete lineage sorting (ILS) give rise to phylogenetic discordance. Fossil clades...

A standard method in phylogenetic reconstruction for representing variation in substitution rates between sites in the genome is the discrete Gamma model (DGM). Relative rates are assumed to be distributed according to a discretised Gamma d...

Plants with amphitropical distributions have closely related populations in both Northern and Southern Hemispheres, but are absent from the intervening tropics. They provide a unique opportunity to study the constraints shaping the distribu...
Phylogenomic discordances reveal conflicting hybridization episodes and widespread lineage-sorting events in temperate Loliinae grasses [0.03%]

Phenotypes serve as the interface between organisms and their environments and are thus pivotal for comprehensive biological understanding. However, comparative analyses of species' phenotypes must account for the non-independence of charac...

Fossilized organisms only represent a small fraction of Earth's evolutionary history, motivating "ancestral state reconstruction" techniques for inferring unobserved phenotypes of evolving lineages based on measurements of their relatives. ...
