A metric on phylogenetic tree shapes [PDF]

open access: yesSystematic Biology, 2016
Abstract The shapes of evolutionary trees are influenced by the nature of the evolutionary process, but comparisons of trees from different processes are hindered by the challenge of completely describing tree shape. We present a full characterization of the shapes of rooted branching trees in a form that lends itself to natural tree ...

On the number of vertices of each rank in phylogenetic trees and their generalizations [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2016
We find surprisingly simple formulas for the limiting probability that the rank of a randomly selected vertex in a randomly selected phylogenetic tree or generalized phylogenetic tree is a given integer.

A synthesis tree of the Copepoda: integrating phylogenetic and taxonomic data reveals multiple origins of parasitism [PDF]

open access: yesPeerJ, 2021
The Copepoda is a clade of pancrustaceans containing 14,485 species that are extremely varied in their morphology and lifestyle. Not only do copepods dominate marine plankton and sediment communities and make up a sizeable component of the freshwater ...

Drawing Phylogenetic Trees [PDF]

open access: yes, 2005
We present linear-time algorithms for drawing phylogenetic trees in radial and circular representations. In radial drawings given edge lengths (representing evolutionary distances) are preserved, but labels (names of taxons represented in the leaves) need to be adjusted, whereas in circular drawings labels are perfectly spread out, but edge lengths ...

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.

Genetic similarities and phylogenetic analysis of Muntjac (Muntiacus spp.) by comparing the nucleotide sequence of 16S rRNA and cytochrome B genome

open access: yesBrazilian Journal of Biology, 2021
This study aimed to identify the phylogenetic similarities among the muntjac (Muntiacus spp.). The phylogenetic similarities among seven major muntjac species were studied by comparing the nucleotide sequence of 16s rRNA and cytochrome b genome ...

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.
