A vectorial tree distance measure
Scientific Reports, 2022 A vectorial distance measure for trees is presented. Given two trees, we define a Tree-Alignment (T-Alignment). We T-align the trees from their centers outwards, starting from the root-branches, to make the next level as similar as possible.

Rearrangement operations on unrooted phylogenetic networks
Theory and Applications of Graphs, 2019 Rearrangement operations transform a phylogenetic tree into another one and hence induce a metric on the space of phylogenetic trees. Popular operations for unrooted phylogenetic trees are NNI (nearest neighbour interchange), SPR (subtree prune and ...

Systematic errors in phylogenetic trees [PDF]
Current Biology, 2021 The effort to reconstruct the tree of life was revolutionized by the use of sequences of proteins and nucleic acids. Phylogenetic trees are now routinely inferred using hundreds of thousands of amino acid or nucleotide characters. It thus seems surprising that many aspects of the tree of life are still controversial; conflicting results between large ...

The agreement distance of unrooted phylogenetic networks [PDF]
Discrete Mathematics & Theoretical Computer Science, 2020 A rearrangement operation makes a small graph-theoretical change to a phylogenetic network to transform it into another one. For unrooted phylogenetic trees and networks, popular rearrangement operations are tree bisection and reconnection (TBR) and ...

ü . On the Construction of a Phylogenetic Tree
Zeitschrift für Naturforschung C, 1979 Abstract Phylogenetic Dendrograms, Molecular Evolution For the construction of a phylogenetic tree an algorithm is described. This, allows the correction of the original data and the proper selection, in each step of the process, of the nearest neighbours of a common ancestor.

Distances Between Phylogenetic Trees: A Survey
Tsinghua Science and Technology, 2013 Phylogenetic trees have been widely used in the study of evolutionary biology for representing the tree-like evolution of a collection of species. However, different data sets and different methods often lead to the construction of different phylogenetic

PhySortR: a fast, flexible tool for sorting phylogenetic trees in R [PDF]
PeerJ, 2016 A frequent bottleneck in interpreting phylogenomic output is the need to screen often thousands of trees for features of interest, particularly robust clades of specific taxa, as evidence of monophyletic relationship and/or reticulated evolution. Here we

Genome rearrangements and phylogeny reconstruction in Yersinia pestis [PDF]
PeerJ, 2018 Genome rearrangements have played an important role in the evolution of Yersinia pestis from its progenitor Yersinia pseudotuberculosis. Traditional phylogenetic trees for Y.

On Tree-Based Phylogenetic Networks [PDF]
Journal of Computational Biology, 2016 A large class of phylogenetic networks can be obtained from trees by the addition of horizontal edges between the tree edges. These networks are called tree based networks. Reticulation-visible networks and child-sibling networks are all tree based. In this work, we present a simply necessary and sufficient condition for tree-based networks and prove ...
