TL;DR: This work analysed gaps in the two most important reference databases, Barcode of Life Data Systems (BOLD) and NCBI GenBank, with a focus on the taxa most frequently used in WFD and MSFD, and found that coverage varies strongly among taxonomic groups, and among geographic regions.

TL;DR: It is shown that large‐scale barcoding inventories of complex biotas are feasible and contribute directly to the evaluation of conservation priorities and it is argued that the evolutionary content of barcode data can be used to detect priority species for future IUCN assessments.

TL;DR: Aquatic biomonitoring has become an essential task in Europe and many other regions as a consequence of strong anthropogenic pressures affecting the health of lakes, rivers, oceans and groundwater as mentioned in this paper.

TL;DR: Results illustrate how a comprehensive DNA barcode reference library can identify unknown specimens, but also reveal how this potential is constrained by gaps in the quantity and quality of records in BOLD, especially for Hymenoptera and Diptera.

TL;DR: This study provides an intermediate taxonomic system for half of the German Dipteran fauna, which will provide a useful foundation for subsequent detailed, integrative taxonomic studies, and demonstrates that species delineation using BINs and operational taxonomic units (OTUs) constitutes an effective method for biodiversity studies using DNA metabarcoding.
