Rapid dissemination of taxonomic discoveries based on DNA barcoding and morphology [PDF]
Scientific Reports, 2016 The taxonomic impediment is characterized by dwindling classical taxonomic expertise, and slow pace of revisionary work, thus more rapid taxonomic assessments are needed.

Unbiased probabilistic taxonomic classification for DNA barcoding [PDF]
Bioinformatics, 2016 Abstract Motivation: When targeted to a barcoding region, high-throughput sequencing can be used to identify species or operational taxonomical units from environmental samples, and thus to study the diversity and structure of species communities.

Quantifying uncertainty of taxonomic placement in DNA barcoding and metabarcoding [PDF]
Methods in Ecology and Evolution, 2016 Summary A crucial step in the use of DNA markers for biodiversity surveys is the assignment of Linnaean taxonomies (species, genus, etc.) to sequence reads. This allows the use of all the information known based on the taxonomic names. Taxonomic placement of DNA barcoding sequences is inherently probabilistic because DNA sequences contain errors ...

DNA barcodes enable higher taxonomic assignments in the Acari [PDF]
Scientific Reports, 2021 AbstractAlthough mites (Acari) are abundant in many terrestrial and freshwater ecosystems, their diversity is poorly understood. Since most mite species can be distinguished by variation in the DNA barcode region of cytochromecoxidase I, the Barcode Index Number (BIN) system provides a reliable species proxy that facilitates large-scale surveys.

DNA barcoding of plants: Selection of core markers for taxonomic groups
Plant Science Today, 2017 Plant identification is a crucial and routine taxonomic procedure in order to understand and conserve the biodiversity. Anthropogenic activity, pollution, deforestation, and exploitation of natural resources have been threatening to the plant biodiversity.

Molecular Ecology Resources, 2020 Improved taxonomic methods are needed to quantify declining populations of insect pollinators. This study devises a high‐throughput DNA barcoding protocol for a regional fauna (United Kingdom) of bees (Apiformes), consisting of reference library ...

bioRxiv, 2020 The Odonata are considered among the most endangered freshwater faunal taxa. Their DNA-based monitoring relies on validated reference datasets that are often lacking or do not cover important biogeographical centres of diversification.

Defining operational taxonomic units using DNA barcode data [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2005 AbstractThe scale of diversity of life on this planet is a significant challenge for any scientific programme hoping to produce a complete catalogue, whatever means is used. For DNA barcoding studies, this difficulty is compounded by the realization that any chosen barcode sequence is not the gene ‘for’ speciation and that taxa have evolutionary ...

Identification of rays through DNA barcoding: an application for ecologists. [PDF]
PLoS ONE, 2012 DNA barcoding potentially offers scientists who are not expert taxonomists a powerful tool to support the accuracy of field studies involving taxa that are diverse and difficult to identify.

DNA Barcoding Diatoms From China With Multiple Genes
Frontiers in Marine Science, 2021 Diatoms play a key role in water quality assessments and algae bloom. However, taxonomic confusion often exists for diatoms, and morphological characters are extremely diverse for species identification.
