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 ...

Ghost-tree: creating hybrid-gene phylogenetic trees for diversity analyses. [PDF]

open access: yes, 2016
BackgroundFungi play critical roles in many ecosystems, cause serious diseases in plants and animals, and pose significant threats to human health and structural integrity problems in built environments.

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 ...

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.

Identifying phylogenetic trees

open access: yesDiscrete Mathematics, 2005
AbstractA central problem that arises in evolutionary biology is that of displaying partitions of subsets of a finite set X on a tree whose vertices are partially labelled with the elements of X. Such a tree is called an X-tree and, for a collection C of partitions of subsets of X, characterisations for the existence and uniqueness of an X-tree that ...

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.

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.

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 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.
