Phylogenetic comparative assembly [PDF]

open access: yesAlgorithms for Molecular Biology, 2009
Recent high throughput sequencing technologies are capable of generating a huge amount of data for bacterial genome sequencing projects. Although current sequence assemblers successfully merge the overlapping reads, often several contigs remain which cannot be assembled any further.

Phylogenetic diversity and biodiversity indices on phylogenetic networks [PDF]

open access: yesMathematical Biosciences, 2018
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.

Tangent Phylogenetic PCA [PDF]

open access: yes, 2023
Phylogenetic PCA (p-PCA) is a version of PCA for observations that are leaf nodes of a phylogenetic tree. P-PCA accounts for the fact that such observations are not independent, due to shared evolutionary history. The method works on Euclidean data, but in evolutionary biology there is a need for applying it to data on manifolds, particularly shapes ...

Phylogenetic relationship and virulence composition of Escherichia coli O26:H11 cattle and human strain collections in Scotland; 2002–2020

open access: yesFrontiers in Microbiology, 2023
O26 is the commonest non-O157 Shiga toxin (stx)-producing Escherichia coli serogroup reported in human infections worldwide. Ruminants, particularly cattle, are the primary reservoir source for human infection.

Polyploid phylogenetics [PDF]

open access: yesNew Phytologist, 2021
SummaryPolyploidy is a dominant feature of extant plant diversity. However, major research questions, including whether polyploidy is important to long‐term evolution or is just ‘evolutionary noise’, remain unresolved due to difficulties associated with the generation and analysis of data from polyploid lineages.
