Mean and Variance of Phylogenetic Trees [PDF]

Systematic Biology, 2019
Abstract We describe the use of the Fréchet mean and variance in the Billera–Holmes–Vogtmann (BHV) treespace to summarize and explore the diversity of a set of phylogenetic trees. We show that the Fréchet mean is comparable to other summary methods, and, despite its stickiness property, is more likely to be binary than the majority-rule ...

Understanding the tree of life: an overview of tree-reading skill frameworks

Evolution: Education and Outreach, 2019
Diagrammatic depictions of evolutionary relationships play an increasingly important role in scientific and educational literature. Reading evolutionary trees is seen as a major challenge for biologists in learning about evolution and its applications in

A QUBO formulation for the Tree Containment problem [PDF]

, 2022
Phylogenetic (evolutionary) trees and networks are leaf-labeled graphs that are widely used to represent the evolutionary relationships between entities such as species, languages, cancer cells, and viruses. To reconstruct and analyze phylogenetic networks, the problem of deciding whether or not a given rooted phylogenetic network embeds a given rooted

The Fair Proportion is a Shapley Value on phylogenetic networks too

, 2018
The Fair Proportion of a species in a phylogenetic tree is a very simple measure that has been used to assess its value relative to the overall phylogenetic diversity represented by the tree.

Confidence Sets for Phylogenetic Trees [PDF]

Journal of the American Statistical Association, 2018
Inferring evolutionary histories (phylogenetic trees) has important applications in biology, criminology and public health. However, phylogenetic trees are complex mathematical objects that reside in a non-Euclidean space, which complicates their analysis.

Viruses in sanctuary chimpanzees across Africa

American Journal of Primatology, Volume 85, Issue 1, January 2023., 2023
Abstract Infectious disease is a major concern for both wild and captive primate populations. Primate sanctuaries in Africa provide critical protection to thousands of wild‐born, orphan primates confiscated from the bushmeat and pet trades. However, uncertainty about the infectious agents these individuals potentially harbor has important implications ...

Multidimensionality of tree communities structure host-parasitoid networks and their phylogenetic composition

eLife
Environmental factors can influence ecological networks, but these effects are poorly understood in the realm of the phylogeny of host-parasitoid interactions.

Conflicting phylogenetic signals in plastomes of the tribe Laureae (Lauraceae) [PDF]

PeerJ, 2020
Background Gene tree discordance is common in phylogenetic analyses. Many phylogenetic studies have excluded non-coding regions of the plastome without evaluating their impact on tree topology. In general, plastid loci have often been treated as a single

Phylogenetic trees and Euclidean embeddings [PDF]

Journal of Mathematical Biology, 2016
It was recently observed by de Vienne et al. that a simple square root transformation of distances between taxa on a phylogenetic tree allowed for an embedding of the taxa into Euclidean space. While the justification for this was based on a diffusion model of continuous character evolution along the tree, here we give a direct and elementary ...

Regulatory effect of gut microbes on blood pressure

Animal Models and Experimental Medicine, Volume 5, Issue 6, Page 513-531, December 2022., 2022
The interaction between gut microbiota and hypertension, the genera which affect the blood pressure in taxonomic level, and the commonly used treatments to hypertension based on the gut microbes were summarized in this review. The increases of Lactobacillus, etc.
