Reconciling taxonomy and phylogenetic inference: formalism and algorithms for describing discord and inferring taxonomic roots

open access: yesAlgorithms for Molecular Biology, 2012
Background Although taxonomy is often used informally to evaluate the results of phylogenetic inference and the root of phylogenetic trees, algorithmic methods to do so are lacking.

Testing phylogenetic hypotheses of the subgenera of the freshwater crayfish genus Cambarus (Decapoda: Cambaridae). [PDF]

open access: yesPLoS ONE, 2012
The genus Cambarus is one of three most species rich crayfish genera in the Northern Hemisphere. The genus has its center of diversity in the Southern Appalachians of the United States and has been divided into 12 subgenera.

Unified phylogenetic species concept: taking subspecies and race out of science: postmodern theory applied to the Potamophylax cingulatus group (Trichoptera, Limnephilidae) [PDF]

open access: yesOpuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, 2018
The subspecies of the biological species concept with incomplete reproductive isolation versus the incipient sibling species of the phylogenetic species concept with permeable reproductive barrier are still applied side by side in the everyday practice ...

Linking 16S rRNA Gene Classification to amoA Gene Taxonomy Reveals Environmental Distribution of Ammonia-Oxidizing Archaeal Clades in Peatland Soils

open access: yesmSystems, 2021
A highly resolved taxonomy for ammonia-oxidizing archaea (AOA) based on the alpha subunit of ammonia monooxygenase (amoA) was recently established, which uncovered novel environmental patterns of AOA, challenging previous generalizations.

Bringing order to a complex system: phenotypic and genotypic evidence contribute to the taxonomy of Tityus (Scorpiones, Buthidae) and support the description of a new species [PDF]

open access: yesZooKeys, 2021
We present a molecular phylogenetic analysis including a survey for overlooked phenotypic characters. Based on both analysis and characters a new cave-dwelling species is described: Tityus (Tityus) spelaeus sp. nov.

Polyphyly in 16S rRNA-based LVTree Versus Monophyly in Whole-genome-based CVTree

open access: yesGenomics, Proteomics & Bioinformatics, 2018
We report an important but long-overlooked manifestation of low-resolution power of 16S rRNA sequence analysis at the species level, namely, in 16S rRNA-based phylogenetic trees polyphyletic placements of closely-related species are abundant compared to ...

Phylogenetic placement and taxonomy of the genus Hederorkis (Orchidaceae). [PDF]

open access: yesPLoS ONE, 2015
Three plastid regions, matK, rpl32-trnL and rpl16 intron and the ITS1-5.8S-ITS2 nuclear ribosomal DNA were used to demonstrate a phylogenetic placement of the genus Hederorkis (Orchidaceae) for the first time.

Automated assembly of a reference taxonomy for phylogenetic data synthesis

open access: yesBiodiversity Data Journal, 2017
Taxonomy and nomenclature data are critical for any project that synthesizes biodiversity data, as most biodiversity data sets use taxonomic names to identify taxa.

Introgression evidence and phylogenetic relationships among three (Para)Misgurnus species as revealed by mitochondrial and nuclear DNA markers [PDF]

open access: yesArchives of Biological Sciences, 2013
The taxonomy of (Para)Misgurnus genera is still debated. We therefore used mitochondrial and nuclear DNA markers to analyze the phylogenetic relationships among Misgurnus anguillicaudatus, Paramisgurnus dabryanus and Misgurnus fossilis ...
