The complete mitochondrial genome of long-tailed red-toothed shrew (Episoriculus leucops) and implication of phylogenetic status

open access: yesMitochondrial DNA. Part B. Resources, 2021
We determined a complete mitochondrial genome of Episoriculus leucops. This mitogenome is a circular molecule with 16,838 bp in length, containing 13 protein-coding genes, 22 transfer RNA genes (tRNA), and two ribosomal RNA genes (rRNA).

Phylogenetic Structure of Tree Species across Different Life Stages from Seedlings to Canopy Trees in a Subtropical Evergreen Broad-Leaved Forest.

open access: yesPLoS ONE, 2015
Investigating patterns of phylogenetic structure across different life stages of tree species in forests is crucial to understanding forest community assembly, and investigating forest gap influence on the phylogenetic structure of forest regeneration is

Molecular Taxonomy Matches Pollen Grains Taxonomy in Differentiation Between Some Caesalpinioideae Taxa [PDF]

open access: yesJournal of Plant Production, 2023
Phylogeny investigation relying on chloroplast genome sequence is an established approach in differentiation between plants derived from related ancestors.

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.

Rearrangement operations on unrooted phylogenetic networks

open access: yesTheory 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 ...

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.

Understanding the tree of life: an overview of tree-reading skill frameworks

open access: yesEvolution: Education and Outreach, 2019
Diagrammatic depictions of evolutionary relationships play an increasingly important role in scientific and educational literature. Reading evolutionary trees is seen as a major challenge for biologists in learning about evolution and its applications in

Systematic errors in phylogenetic trees [PDF]

open access: yesCurrent 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 ...

A new resolution function to evaluate tree shape statistics.

open access: yesPLoS ONE, 2019
Phylogenetic trees are frequently used in biology to study the relationships between a number of species or organisms. The shape of a phylogenetic tree contains useful information about patterns of speciation and extinction, so powerful tools are needed ...

Conflicting phylogenetic signals in plastomes of the tribe Laureae (Lauraceae) [PDF]

open access: yesPeerJ, 2020
Background Gene tree discordance is common in phylogenetic analyses. Many phylogenetic studies have excluded non-coding regions of the plastome without evaluating their impact on tree topology. In general, plastid loci have often been treated as a single
