Trees

open access: yes, 2023
Sets of complete trees generated by TACT (n=100) and DNA-only trees (n=100) necessary to run PLRs and phylogenetic signal analyses using the scripts in: https://github.com/RobRozzi ...

Small RNA pathways in mammalian oocytes

open access: yesFEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Cherry picking in forests: A new characterization for the unrooted hybrid number of two phylogenetic trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science
Phylogenetic networks are a special type of graph which generalize phylogenetic trees and that are used to model non-treelike evolutionary processes such as recombination and hybridization. In this paper, we consider {\em unrooted} phylogenetic networks,

A strict upper bound for the partition distance and the cluster distance of phylogenetic trees for each fixed pair of topological trees. [PDF]

open access: yesPLoS ONE, 2018
For each given pair of (rooted or unrooted) topological trees with the same number of leaves a strict upper bound is shown for the tree partition distance (also called symmetric difference metric and Robinson-Foulds distance)-in case of unrooted trees ...

Using Trees: Myrmecocystus Phylogeny and Character Evolution and New Methods for Investigating Trait Evolution and Species Delimitation (PhD Dissertation) [PDF]

open access: yes, 2008
1) Rates of phenotypic evolution have changed throughout the history of life, producing variation in levels of morphological, functional, and ecological diversity among groups.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

open access: yesFEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

TreeSwift: A massively scalable Python tree package

open access: yesSoftwareX, 2020
Phylogenetic trees are essential to evolutionary biology, and numerous methods exist that attempt to extract phylogenetic information applicable to a wide range of disciplines, such as epidemiology and metagenomics.

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

open access: yesFEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Climate-Niche Evolution in Leaf-Warblers (Aves: Phylloscopidae): A Matter of Phylogeny

open access: yesDiversity
Macroevolutionary studies which focus on the development of traits in a phylogenetic context are increasingly used to explore the evolutionary mechanisms and processes that have led to the diversity in species we see today. This includes the study of the
