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.

A New Phylogenetic Inference Based on Genetic Attribute Reduction for Morphological Data

open access: yesEntropy, 2019
To address the instability of phylogenetic trees in morphological datasets caused by missing values, we present a phylogenetic inference method based on a concept decision tree (CDT) in conjunction with attribute reduction.

Classes of tree-based networks

open access: yesVisual Computing for Industry, Biomedicine, and Art, 2020
Recently, so-called tree-based phylogenetic networks have attracted considerable attention. These networks can be constructed from a phylogenetic tree, called the base tree, by adding additional edges.

Phylogenetic impoverishment of Amazonian tree communities in an experimentally fragmented forest landscape. [PDF]

open access: yesPLoS ONE, 2014
Amazonian rainforests sustain some of the richest tree communities on Earth, but their ecological and evolutionary responses to human threats remain poorly known.

A Stochastic Model for Phylogenetic Trees [PDF]

open access: yesJournal of Applied Probability, 2009
We propose the following simple stochastic model for phylogenetic trees. New types are born and die according to a birth and death chain. At each birth we associate a fitness to the new type sampled from a fixed distribution. At each death the type with the smallest fitness is killed. We show that if the birth (i.e.

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

Phylogenetic mixtures on a single tree can mimic a tree of another topology [PDF]

open access: yes, 2007
Phylogenetic mixtures model the inhomogeneous molecular evolution commonly observed in data. The performance of phylogenetic reconstruction methods where the underlying data is generated by a mixture model has stimulated considerable recent debate.

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).

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 ...
