Two metrics for general phylogenetic networks [PDF]

open access: yesarXiv, 2008
We prove that Nakhleh's latest dissimilarity measure for phylogenetic networks separates distinguishable phylogenetic networks, and that a slight modification of it provides a true distance on the class of all phylogenetic networks.

Transforming phylogenetic networks: Moving beyond tree space [PDF]

open access: yesarXiv, 2016
Phylogenetic networks are a generalization of phylogenetic trees that are used to represent reticulate evolution. Unrooted phylogenetic networks form a special class of such networks, which naturally generalize unrooted phylogenetic trees. In this paper we define two operations on unrooted phylogenetic networks, one of which is a generalization of the ...

A consensus on the Aquaporin Gene Family in the Allotetraploid Plant, Nicotiana tabacum

open access: yesPlant Direct, 2021
Aquaporins (AQPs) are membrane‐spanning channel proteins with exciting applications for plant engineering and industrial applications. Translational outcomes will be improved by better understanding the extensive diversity of plant AQPs.

Phylogenetic diversity and biodiversity indices on phylogenetic networks [PDF]

open access: yesarXiv, 2017
In biodiversity conservation it is often necessary to prioritize the species to conserve. Existing approaches to prioritization, e.g. the Fair Proportion Index and the Shapley Value, are based on phylogenetic trees and rank species according to their contribution to overall phylogenetic diversity.

An introduction to phylogenetic analyses and modelling in ecology [PDF]

open access: yesComputational Ecology and Software, 2015
Phylogenetic systematics seeks to describe and reconstruct the evolutionary relationships among and between organisms making use of molecular data. This field has become immensely popular in recent years, with the associated computational demands growing

TreeOTU: Operational Taxonomic Unit Classification Based on Phylogenetic Trees [PDF]

open access: yesarXiv, 2013
Our current understanding of the taxonomic and phylogenetic diversity of cellular organisms, especially the bacteria and archaea, is mostly based upon studies of sequences of the small- subunit rRNAs (ssu-rRNAs). To address the limitation of ssu-rRNA as a phylogenetic marker, such as copy number variation among organisms and complications introduced by

On Nakhleh's latest metric for phylogenetic networks [PDF]

open access: yesarXiv, 2008
We prove that Nakhleh's latest dissimilarity measure for phylogenetic networks is a metric on the classes of tree-child phylogenetic networks, of semi-binary time consistent tree-sibling phylogenetic networks, and of multi-labeled phylogenetic trees. We also prove that it distinguishes phylogenetic networks with different reduced versions. In this way,

Complete mitochondrial genome and the phylogenetic position of the Lake Eyre hardyhead (Craterocephalus eyresii), a freshwater atherinid fish endemic to Lake Eyre Basin, South Australia

open access: yesMitochondrial DNA. Part B. Resources, 2017
The Lake Eyre hardyhead (Craterocephalus eyresii) is an endemic freshwater fish living in the Lake Eyre basin in South Australia. Here, I report the full mitogenome description and the phylogenetic position of this species based on the mitogenome ...

Morphological phylogenetics of Bignoniaceae Juss.

open access: yesBeni-Suef University Journal of Basic and Applied Sciences, 2014
The most recent classification of Bignoniaceae recognized seven tribes, Phylogenetic and monographic studies focusing on clades within Bignoniaceae had revised tribal and generic boundaries and species numbers for several groups, the portions of the ...
