TLDR
This work proposes a scheme in which DNA would be the scaffold of a taxonomic reference system, whilst maintaining the importance of the morphological information associated with whole specimens.Abstract:
Taxonomy underpins all biological research, with implications for many basic scientific and applied fields. Insights into the stability or change of animal and plant guilds require species identification on a broad scale and biodiversity questions have become a major public issue. But this comes at a time when taxonomy is facing a crisis, because ever fewer specialists are available. Here, we explore the possibility of using DNA-based methodology to overcome these problems. The utility of DNA sequences for taxonomic purposes is well established. However, all current taxonomic approaches intend to use DNA, at best, as an auxiliary criterion for identifying a species or a taxon, but have not given it a central role. We propose a scheme in which DNA would be the scaffold of a taxonomic reference system, whilst maintaining the importance of the morphological information associated with whole specimens.read more

Barcoding animal life: cytochrome c oxidase subunit 1 divergences among closely related species
TL;DR: It is indicated that sequence divergences at COI regularly enable the discrimination of closely allied species in all animal phyla except the Cnidaria and constraints on intraspecific mitochondrial DNA divergence arising through selective sweeps mediated via interactions with the nuclear genome.

DNA barcoding Australia's fish species
TL;DR: It is concluded that cox1 sequencing, or ‘barcoding’, can be used to identify fish species.

TL;DR: In this paper, the authors use mitochondrial DNA variation to delimit species in a poorly known beetle radiation in the genus Rivacindela from arid Australia, using a new likelihood method that determines the point of transition from species-level (speciation and extinction) to population-level evolutionary processes.
Journal ArticleDOI
Towards integrative taxonomy
TL;DR: Seven guidelines are proposed to help integrative taxonomists recognize cases when species are supported by broad biological evidence and therefore are deserving of an official name and to prevent the over-abundance of both synonyms and names of doubtful application from worsening.

DNA barcoding and taxonomy in Diptera: a tale of high intraspecific variability and low identification success.
TL;DR: An outlook on the prospects of obtaining complete barcode databases and the future use of DNA sequences in a modern integrative taxonomy is concluded.

Biological identifications through DNA barcodes
TL;DR: It is established that the mitochondrial gene cytochrome c oxidase I (COI) can serve as the core of a global bioidentification system for animals and will provide a reliable, cost–effective and accessible solution to the current problem of species identification.

The species concept for prokaryotes.
Ramon Rosselló-Móra,Rudolf Amann +1 more
TL;DR: The species concept is a recurrent controversial issue that preoccupies philosophers as well as biologists of all disciplines as discussed by the authors, and it has been widely accepted as useful, pragmatic and universally applicable within the prokaryotic world.

TL;DR: This work sequenced up to 803 base pairs of mitochondrial DNA from 14 representative Victorian species and 23 additional African species to study the 'flock' of cichlid fishes in Lake Victoria.
