Genome rearrangements and phylogeny reconstruction in Yersinia pestis [PDF]

open access: yesPeerJ, 2018
Genome rearrangements have played an important role in the evolution of Yersinia pestis from its progenitor Yersinia pseudotuberculosis. Traditional phylogenetic trees for Y.

A parsimony-based metric for phylogenetic trees [PDF]

open access: yes, 2015
In evolutionary biology various metrics have been defined and studied for comparing phylogenetic trees. Such metrics are used, for example, to compare competing evolutionary hypotheses or to help organize algorithms that search for optimal trees. Here we

Sound Colless-like balance indices for multifurcating trees. [PDF]

open access: yesPLoS ONE, 2018
The Colless index is one of the most popular and natural balance indices for bifurcating phylogenetic trees, but it makes no sense for multifurcating trees.

Representing non-crossing cuts by phylogenetic trees

open access: yesElectronic Journal of Graph Theory and Applications, 2021
Phylogenetic trees are representations of the evolutionary descendency of a set of species. In graph-theoretic terms, a phylogenetic tree is a partially labeled tree where unlabeled vertices have at least degree three and labels corresponds to pairwise ...

In the Light of Deep Coalescence: Revisiting Trees Within Networks [PDF]

open access: yes, 2016
Phylogenetic networks model reticulate evolutionary histories. The last two decades have seen an increased interest in establishing mathematical results and developing computational methods for inferring and analyzing these networks.

The Shapley Value of Phylogenetic Trees [PDF]

open access: yes, 2007
Every weighted tree corresponds naturally to a cooperative game that we call a "tree game"; it assigns to each subset of leaves the sum of the weights of the minimal subtree spanned by those leaves.

Phylogenetic diversity and biodiversity indices on phylogenetic networks

open access: yes, 2018
In biodiversity conservation it is often necessary to prioritize the species to conserve. Existing approaches to prioritization, e.g. the Fair Proportion Index and the Shapley Value, are based on phylogenetic trees and rank species according to their ...

Bayesian phylogenetic and phylodynamic data integration using BEAST 1.10

open access: yesVirus Evolution, 2018
The Bayesian Evolutionary Analysis by Sampling Trees (BEAST) software package has become a primary tool for Bayesian phylogenetic and phylodynamic inference from genetic sequence data.

Visualising very large phylogenetic trees in three dimensional hyperbolic space

open access: yesBMC Bioinformatics, 2004
Background Common existing phylogenetic tree visualisation tools are not able to display readable trees with more than a few thousand nodes. These existing methodologies are based in two dimensional space.

A fast algorithm for the multiple genome rearrangement problem with weighted reversals and transpositions

open access: yesBMC Bioinformatics, 2008
Background Due to recent progress in genome sequencing, more and more data for phylogenetic reconstruction based on rearrangement distances between genomes become available. However, this phylogenetic reconstruction is a very challenging task.
