The ways in which patterns of intraspecific and interspecific genetic divergences in the barcode region can provide rapid insights into the taxonomic identity, morphological features, and geographical distributions of species are considered.

The findings reveal the great utility of building a well-populated, species-level reference barcode database against which to compare unknowns and the importance of addressing taxonomic issues.
Species diversity and endemism in the Daphnia of Argentina: a genetic investigation
- S. Adamowicz, P. Hebert, M. C. Marinone
- Environmental Science
- 1 February 2004
Analysis of mitochondrial DNA sequences and allozyme variation from 176 Daphnia populations from Argentina established the presence of at least 15 species in Argentina, six of which are either undescribed or are currently misidentified and two of which represent range extensions of North American taxa.
High sensitivity of 454 pyrosequencing for detection of rare species in aquatic communities

- 1 June 2013
The extreme sensitivity of pyrosequencing using rare species spiked into plankton samples is demonstrated and it is proposed that the method is a powerful tool for detection of rare native and/or alien species.
Molecular systematics and patterns of morphological evolution in the Centropagidae (Copepoda: Calanoida) of Argentina
- S. Adamowicz, S. Menu-Marque, P. Hebert, A. Purvis
- 1 February 2007
The results suggest that structures may be gained readily as well as lost in centropagid copepods, and the common assumption that evolution tends to proceed via the loss of structures in crustaceans is evaluated.
Towards a comprehensive barcode library for arctic life - Ephemeroptera, Plecoptera, and Trichoptera of Churchill, Manitoba, Canada

The correlation between the morphological species delineations, DNA barcode-based haplotype clusters delimited by a sequence threshold (2%), and a threshold-free approach to biodiversity quantification--phylogenetic diversity are explored.
Prospects for using DNA barcoding to identify spiders in species-rich genera

- 29 July 2009
Examination of intra- and interspecifi c divergences for 19 genera that were each represented by at least 10 morphospecies finds the need for a taxonomic approach that combines both morphological and molecular methods, and examines the prevalence of a “barcode gap”.
Comparative phylogeography of two North American ‘glacial relict’ crustaceans

- 14 November 2006
This study used a mitochondrial gene, cytochrome c oxidase subunit I, to examine and compare the phylogeographical structure of two glacial relict crustaceans (Limnocalanus macrurus and members of the Mysis relicta species group) across North America, finding a sharp phylogenetic division between populations from inland lakes formed during glacial retreat, and arctic lakes isolated from polar seas via isostatic rebound.
How many branchiopod crustacean species are there? Quantifying the components of underestimation
- S. Adamowicz, A. Purvis
- Environmental Science, Biology
- 18 August 2005
A proper understanding of species boundaries in nature is key in accurately estimating species richness for invertebrate groups, and it is suggested that while many species remain to be described, numbers of presently described species are still useful for macroevolutionary studies of diversification when interpreted with caution.
