While many legal aspects of biodiversity are national, biodiversity itself is international. With the survey of Central European orthopterans a first joint project was started from GBOL (German Barcode of Life), SwissBOL (Swiss Barcode of Life) and ABOL. About 125 species of orthopterans are known from Austria. Some of them can be delimited from each other only by bioacoustics. The joint project aimed to provide first DNA-Barcoding data from orthopterans of Germany, Switzerland and Austria.
Within this international project, a total of 748 barcodes of 127 of the 162 species that can be found in the DACH region were generated, with 29 barcodes of 14 species from Austria (see also Hawlitschek et al. 2016). For 93 of the investigated species the determination with barcodes is reliable. This is not the case for the remaining species, as the same barcode can occur in several taxa and even in different genera. Hybridization and lineage sorting are the most likely explanations for this phenomenon. All barcodes are available on BOLD for future investigations.
