The biodiversity of soil communities remains very poorly known and understood. Soil biological sciences are strongly affected by the taxonomic crisis, and most groups of animals in that biota suffer from a strong taxonomic impediment. The objective of this work was to investigate how DNA barcoding - a novel method using a microgenomic tag for species identification and discrimination - permits better evaluation of the taxonomy of soil biota. A total of 1,152 barcode sequences were analyzed for two major groups of animals, collembolans and earthworms, which presented broad taxonomic and geographic sampling. Besides strongly reflecting the taxonomic impediment for both groups, with a large number of species-level divergent lineages remaining unnamed so far,...

DNA barcoding and traditional taxonomy unified through Integrative Taxonomy: a view that challenges the debate questioning both methodologies

The taxonomic crisis, emphasized in recent years, is marked by the lack of popularity (lack of interest in taxonomy) and financial incentives to study biodiversity. This situation, coupled with the issues involved with the necessity of knowing many yet undiscovered species, has meant that new technologies, including the use of DNA, have emerged to revitalize taxonomy. Part of the scientific community, however, has rejected the use of these innovative ideas. DNA barcoding has especially been the target of numerous criticisms regarding its application, as opposed to the use of morphology. This paper aims to highlight the inconsistency of the debate involving DNA versus morphology, since there is a proposal for the integration of traditional taxonomy and DNA...
