ü . On the Construction of a Phylogenetic Tree

open access: yesZeitschrift 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

open access: yesTsinghua 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]

open access: yesPeerJ, 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

The agreement distance of unrooted phylogenetic networks [PDF]

open access: yesDiscrete 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 ...

Information geometry for phylogenetic trees [PDF]

open access: yesJournal of Mathematical Biology, 2021
AbstractWe propose a new space of phylogenetic trees which we callwald space. The motivation is to develop a space suitable for statistical analysis of phylogenies, but with a geometry based on more biologically principled assumptions than existing spaces: in wald space, trees are close if they induce similar distributions on genetic sequence data.

Louse (Insecta : Phthiraptera) mitochondrial 12S rRNA secondary structure is highly variable [PDF]

open access: yes, 2002
Lice are ectoparasitic insects hosted by birds and mammals. Mitochondrial 12S rRNA sequences obtained from lice show considerable length variation and are very difficult to align.

Coalescent-based genome analyses resolve the early branches of the euarchontoglires [PDF]

open access: yes, 2013
Despite numerous large-scale phylogenomic studies, certain parts of the mammalian tree are extraordinarily difficult to resolve. We used the coding regions from 19 completely sequenced genomes to study the relationships within the super-clade ...

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.

On Tree-Based Phylogenetic Networks [PDF]

open access: yesJournal 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 ...
