Dimensions of Group-based Phylogenetic Mixtures
Hector Baños, Nathaniel Bushek, Ruth Davidson +6
In this paper we study group-based Markov models of evolution and their mixtures. In the algebreo-geometric setting, group-based phylogenetic tree models correspond to toric variet…
The effect of gene flow on coalescent-based species-tree inference
Colby Long, Laura Kubatko
Most current methods for inferring species-level phylogenies under the coalescent model assume that no gene flow occurs following speciation. While some studies have examined the i…
Distinguishing Phylogenetic Networks
Elizabeth Gross, Colby Long
Phylogenetic networks are becoming increasingly popular in phylogenetics since they have the ability to describe a wider range of evolutionary events than their tree counterparts.…
L-infinity optimization to linear spaces and phylogenetic trees
Daniel Irving Bernstein, Colby Long
Given a distance matrix consisting of pairwise distances between species, a distance-based phylogenetic reconstruction method returns a tree metric or equidistant tree metric (ultr…
Identifiability and Reconstructibility of Species Phylogenies Under a Modified Coalescent
Colby Long, Laura Kubatko
Coalescent models of evolution account for incomplete lineage sorting by specifying a species tree parameter which determines a distribution on gene trees. It has been shown that t…
