Summary/Abstract: DNA barcodes are short DNA fragments standardized for accurate and rapid species identification. They are successfully applied in taxonomic identification of new organisms as well as in detecting illegal trade of endangered species and poaching. DNA barcodes are used also in metabarcoding, i.e. identification of whole sets of different species from environmental samples such as water, soil or feces. Combination with the next-generation sequencing technology allows to reconstruct biodiversity in the past (permafrost samples) and describe its current state in any environment. Metabarcoding enables the identification of diet components of the species based on the DNA from its stools. This method is much faster and easier to analyze even the most complex diet, which provides data to the protection of endangered species or facilitates the management of game animals.
