Improving Bayesian population dynamics inference: A coalescent - based model for multiple loci

This is likely the first time that coarse - graining, a physics principle, and Λ - coalescents, a set of mathematical models, have been used to address questions in ecology.

Instead, they found another family of mathematical models, called Λ - coalescents, are better able to describe the unique patterns of diversification.

A maximum pseudo-likelihood approach for estimating species trees under the coalescent model

To determine if ILS affected the concatenated tree analyses, we explored whether a multispecies coalescent model leads to a different tree topology.

We also developed a statistical binning approach that improves multispecies coalescent analyses for handling gene trees with low phylogenetic signal to infer a species tree (SM5)(58).
