Plant DNA Barcodes, Taxonomic Management, and Species Discovery in Tropical Forests [PDF]

open access: yes, 2012
DNA barcodes have great potential for species identification and taxonomic discovery in tropical forests. This use of DNA barcodes requires a reference DNA library of known taxa with which to match DNA from unidentified specimens. At an even more basic level, it presupposes that the species in the regional species pool have Latin binomials. This is not

Inferring taxonomic placement from DNA barcoding aiding in discovery of new taxa

open access: yesMethods in Ecology and Evolution, 2022
Abstract Predicting the taxonomic affiliation of DNA sequences collected from biological samples is a fundamental step in biodiversity assessment. This task is performed by leveraging existing databases containing reference DNA sequences endowed with a taxonomic ...

Reverse taxonomy for elucidating diversity of insect-associated nematodes: a case study with termites [PDF]

open access: yes, 2012
BACKGROUND: The molecular operational taxonomic unit(MOTU)has recently been applied to microbial and microscopic animal biodiversity surveys. However, in many cases, some of the MOTUs cannot be definitively tied to any of the taxonomic groups in current ...

The species identification problem in mirids (Hemiptera: Heteroptera) highlighted by DNA barcoding and species delimitation studies

open access: yesThe European Zoological Journal, 2020
Due to the difficulties associated with detecting and correctly identifying mirids, developing an accurate species identification approach is crucial, especially for potential harmful species.

Integrated Taxonomy Reveals Hidden Diversity in Northern Australian Fishes: A New Species of Seamoth (Genus Pegasus). [PDF]

open access: yesPLoS ONE, 2016
Fishes are one of the most intensively studied marine taxonomic groups yet cryptic species are still being discovered. An integrated taxonomic approach is used herein to delineate and describe a new cryptic seamoth (genus Pegasus) from what was ...

The importance of taxonomic resolution for additive beta diversity as revealed through DNA barcoding [PDF]

open access: yesGenome, 2016
Additive diversity partitioning (α, β, and γ) is commonly used to study the distribution of species-level diversity across spatial scales. Here, we first investigate whether published studies of additive diversity partitioning show signs of difficulty attaining species-level resolution due to inherent limitations with morphological identifications ...

Metabarcoding is powerful yet still blind : a comparative analysis of morphological and molecular surveys of seagrass communities [PDF]

open access: yes, 2015
In the context of the sixth wave of extinction, reliable surveys of biodiversity are increasingly needed to infer the cause and consequences of species and community declines, identify early warning indicators of tipping points, and provide reliable ...

The promise of a DNA taxonomy [PDF]

open access: yes, 2004
Not only is the number of described species a very small proportion of the estimated extant number of taxa, but it also appears that all concepts of the extent and boundaries of 'species' fail in many cases.

DNA barcoding Brooklyn (New York): A first assessment of biodiversity in Marine Park by citizen scientists.

open access: yesPLoS ONE, 2018
DNA barcoding is both an important research and science education tool. The technique allows for quick and accurate species identification using only minimal amounts of tissue samples taken from any organism at any developmental phase.

Development of mitochondrial DNA cytochrome c oxidase subunit I primer sets to construct DNA barcoding library using next-generation sequencing [PDF]

open access: yesBiodiversity Data Journal
Insects are one of the most diverse eukaryotic groups on the planet, with one million or more species present, including those yet undescribed. The DNA barcoding system has been developed, which has aided in the identification of cryptic species and ...
