Consistency Properties of Species Tree Inference by Minimizing Deep Coalescences [PDF]

open access: yes, 2011
Methods for inferring species trees from sets of gene trees need to account for the possibility of discordance among the gene trees. Assuming that discordance is caused by incomplete lineage sorting, species tree estimates can be obtained by finding ...

Effects of discordance between species and gene trees on phylogenetic diversity conservation

open access: yesJournal of Mathematical Biology, 2022
Phylogenetic diversity indices such as the Fair Proportion (FP) index are frequently discussed as prioritization criteria in biodiversity conservation. They rank species according to their contribution to overall diversity by taking into account the unique and shared evolutionary history of each species as indicated by its placement in an underlying ...

Discordance of Species Trees with Their Most Likely Gene Trees: The Case of Five Taxa [PDF]

open access: yesSystematic Biology, 2008
Under a coalescent model for within-species evolution, gene trees may differ from species trees to such an extent that the gene tree topology most likely to evolve along the branches of a species tree can disagree with the species tree topology. Gene tree topologies that are more likely to be produced than the topology that matches that of the species ...

TreeShrink: fast and accurate detection of outlier long branches in collections of phylogenetic trees

open access: yesBMC Genomics, 2018
Background Sequence data used in reconstructing phylogenetic trees may include various sources of error. Typically errors are detected at the sequence level, but when missed, the erroneous sequences often appear as unexpectedly long branches in the ...

Third-codon transversion rate-based _Nymphaea_ basal angiosperm phylogeny -- concordance with developmental evidence [PDF]

open access: yes, 2007
Flowering plants (angiosperms) appeared on Earth rather suddenly approximately 130 million years ago and underwent a massive expansion in the subsequent 10-12 million years.

Primate phylogenomics uncovers multiple rapid radiations and ancient interspecific introgression.

open access: yesPLoS Biology, 2020
Our understanding of the evolutionary history of primates is undergoing continual revision due to ongoing genome sequencing efforts. Bolstered by growing fossil evidence, these data have led to increased acceptance of once controversial hypotheses ...

Extensive introgression among strongylocentrotid sea urchins revealed by phylogenomics

open access: yesEcology and Evolution, 2023
Gametic isolation is thought to play an important role in the evolution of reproductive isolation in broadcast‐spawning marine invertebrates. However, it is unclear whether gametic isolation commonly evolves early in the speciation process or only ...

Who Watches the Watchmen? An Appraisal of Benchmarks for Multiple Sequence Alignment [PDF]

open access: yes, 2012
Multiple sequence alignment (MSA) is a fundamental and ubiquitous technique in bioinformatics used to infer related residues among biological sequences. Thus alignment accuracy is crucial to a vast range of analyses, often in ways difficult to assess in ...

Relative performance of customized and universal probe sets in target enrichment: A case study in subtribe Malinae

open access: yesApplications in Plant Sciences, 2021
Premise Custom probe design for target enrichment in phylogenetics is tedious and often hinders broader phylogenetic synthesis. The universal angiosperm probe set Angiosperms353 may be the solution.
