A systematic study of the Trachylepis varia complex was conducted using mitochondrial and nuclear DNA markers for individuals sampled across the species range. The taxonomic history of T. varia has been complicated and its broad geographic distribution and considerable phenotypic variation has made taxonomic revision difficult, leading earlier taxonomists to suggest that T. varia is a species complex. We used maximum likelihood and Bayesian inference to estimate gene trees and a multilocus time-tree, respectively, and we used these trees to identify the major clades (putative species) within T...

Efforts to taxonomically delineate species are often confounded with conflicting information and subjective interpretation. Advances in genomic methods have resulted in a new approach to taxonomic identification that stands to greatly reduce much of this conflict. This approach is ideal for species complexes, where divergence times are recent (evolutionarily) and lineages less well defined. The California Roach/Hitch fish species complex is an excellent example, experiencing a convoluted geologic history, diverse habitats, conflicting species designations and potential admixture between species...

Transposons (TEs) shape genomes via recombination and transposition, lead to chromosomal rearrangements, create new gene neighbourhoods and alter gene expression. They play key roles in adaptation either to symbiosis in Amanita genus or to pathogenicity in Pyrenophora tritici-repentis. Despite growing evidence of their importance, the abundance and distribution of mobile elements replicating in a "cut and paste" fashion is barely described so far. In order to improve our knowledge on this old and ubiquitous class of transposable elements, 1,730 fungal genomes were scanned using both de novo and homology-based approaches...

Introduction: Radiology plays a crucial role in the emergency care setting by delivering early and precise diagnoses under pressure of time, right at the beginning of patient treatment. Although there is a need for postgraduate education in emergency radiology, most of the national bodies responsible do not offer it in a uniform fashion and a general proof of qualification is missing in Europe. Therefore, the European Society of Radiology (ESR) has founded the (Sub-)Society of Emergency Radiology (ESER), prompting them to develop a European curriculum...

Resolving relationships among members of the yellow and citrine wagtail species complexes is among the greatest challenges in avian systematics due to arguably the most dramatic disagreements between traditional taxonomy and mtDNA phylogeny. Each species complex is divided into three geographically cohesive mtDNA clades. Each clade from one species complex has a sister from the other complex. Furthermore, one cross-complex pair is more distantly related to the remaining two pairs than are several other wagtail species...

Molecular and morphological research often suggest conflicting results. Selective pressure on certain morphologies can confound understanding of evolutionary relationships. Dacini is one of the most diverse tribes of tephritid flies and contains many economically important pest species. Their black and yellow patterned body markings are presumed to act as wasp mimicry, and the characters separating species and groups are limited and in some cases phenotypically plastic. The traditional taxonomy of the tribe is controversial because groupings are based on unique combinations of morphological characters without the use of cladistic methods, though recent phylogenetic and taxonomic analyses have resulted in significant changes to their taxonomy...

For decades, bacterial taxonomy has been based on in vitro molecular biology techniques and comparison of molecular marker sequences to measure the degree of genetic similarity and deduce phylogenetic relatedness of novel bacterial species with reference microbial taxa. Due to the advent of the genomic era, access to complete bacterial genome contents has become easier, thereby presenting the opportunity to precisely investigate the overall genetic diversity of microorganisms. Here, we describe a high-accuracy phylogenomic approach to assess the taxonomy of members of the genus Bifidobacterium and identify apparent misclassifications in current bifidobacterial taxonomy...

Medical school assessments should foster the development of higher-order thinking skills to support clinical reasoning and a solid foundation of knowledge. Multiple-choice questions (MCQs) are commonly used to assess student learning, and well-written MCQs can support learner engagement in higher levels of cognitive reasoning such as application or synthesis of knowledge. Bloom's taxonomy has been used to identify MCQs that assess students' critical thinking skills, with evidence suggesting that higher-order MCQs support a deeper conceptual understanding of scientific process skills...

A taxonomy is a standardized framework to classify and organize items into categories. Hierarchical taxonomies are ubiquitous, ranging from the classification of organisms to the file system on a computer. Characterizing the typical distribution of items within taxonomic categories is an important question with applications in many disciplines. Ecologists have long sought to account for the patterns observed in species-abundance distributions (the number of individuals per species found in some sample), and computer scientists study the distribution of files per directory...

BACKGROUND: One of the most crucial steps in high-throughput sequence-based microbiome studies is the taxonomic assignment of sequences belonging to operational taxonomic units (OTUs). Without taxonomic classification, functional and biological information of microbial communities cannot be inferred or interpreted. The internal transcribed spacer (ITS) region of the ribosomal DNA is the conventional marker region for fungal community studies. While bioinformatics pipelines that cluster reads into OTUs have received much attention in the literature, less attention has been given to the taxonomic classification of these sequences, upon which biological inference is dependent...
