jsPhyloSVG: a javascript library for visualizing interactive and vector-based phylogenetic trees on the web. [PDF]

open access: yesPLoS ONE, 2010
Many software packages have been developed to address the need for generating phylogenetic trees intended for print. With an increased use of the web to disseminate scientific literature, there is a need for phylogenetic trees to be viewable across many ...

Analysis on Algorithms for Constructing Phylogenetic Trees From Distances

open access: yesIEEE Access, 2019
Neighbour-joining algorithm (NJ for short) is an used widely algorithm for constructing phylogenetic trees from distances because of its high accuracy. For NJ costs a lot of time to construct phylogenetic trees for the large input data, it does not often

Generating normal networks via leaf insertion and nearest neighbor interchange

open access: yesBMC Bioinformatics, 2019
Background Galled trees are studied as a recombination model in theoretical population genetics. This class of phylogenetic networks has been generalized to tree-child networks and other network classes by relaxing a structural condition imposed on ...

Spaces of phylogenetic networks from generalized nearest-neighbor interchange operations [PDF]

open access: yes, 2015
Phylogenetic networks are a generalization of evolutionary or phylogenetic trees that are used to represent the evolution of species which have undergone reticulate evolution.

TreeShrink: fast and accurate detection of outlier long branches in collections of phylogenetic trees

open access: yesBMC Genomics, 2018
Sequence data used in reconstructing phylogenetic trees may include various sources of error. Typically errors are detected at the sequence level, but when missed, the erroneous sequences often appear as unexpectedly long branches in the inferred ...

Tropical principal component analysis on the space of phylogenetic trees

open access: yesBioinform., 2020
MOTIVATION Due to new technology for efficiently generating genome data, machine learning methods are urgently needed to analyze large sets of gene trees over the space of phylogenetic trees.

TreeSwift: A massively scalable Python tree package

open access: yesSoftwareX, 2020
Phylogenetic trees are essential to evolutionary biology, and numerous methods exist that attempt to extract phylogenetic information applicable to a wide range of disciplines, such as epidemiology and metagenomics.

Decreased cold‐sensing function of the transient receptor potential channel TRPM8 from tailed amphibians

open access: yesFEBS Open Bio, EarlyView.
Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

A strict upper bound for the partition distance and the cluster distance of phylogenetic trees for each fixed pair of topological trees. [PDF]

open access: yesPLoS ONE, 2018
For each given pair of (rooted or unrooted) topological trees with the same number of leaves a strict upper bound is shown for the tree partition distance (also called symmetric difference metric and Robinson-Foulds distance)-in case of unrooted trees ...

The Future of Systematics: Tree-Thinking Without the Tree [PDF]

open access: yes, 2012
Phylogenetic trees are meant to represent the genealogical history of life and apparently derive their justification from the existence of the tree of life and the fact that evolutionary processes are tree-like.
