All galls are divided into three or more parts: recursive enumeration of labeled histories for galled trees

open access: yesAlgorithms for Molecular Biology, 2023
Objective In mathematical phylogenetics, a labeled rooted binary tree topology can possess any of a number of labeled histories, each of which represents a possible temporal ordering of its coalescences.

Are allometric model parameters of aboveground biomass for trees phylogenetically constrained?

open access: yesPlant Diversity, 2023
Knowledge of which biological and functional traits have, or lack, phylogenetic signal in a particular group of organisms is important to understanding the formation and functioning of biological communities.

Folding and unfolding phylogenetic trees and networks [PDF]

open access: yes, 2015
Phylogenetic networks are rooted, labelled directed acyclic graphs which are commonly used to represent reticulate evolution. There is a close relationship between phylogenetic networks and multi-labelled trees (MUL-trees).

The identifiability of tree topology for phylogenetic models, including covarion and mixture models [PDF]

open access: yes, 2005
For a model of molecular evolution to be useful for phylogenetic inference, the topology of evolutionary trees must be identifiable. That is, from a joint distribution the model predicts, it must be possible to recover the tree parameter.

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 ...

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.
