As part of the BenthQual project, a comprehensive reference library of the marker gene cytochrome c oxidase I (COI) for macrozoobenthos in the Baltic Sea is being created. The reference library will include all known species of macrozoobenthos in the Baltic Sea (including neobiota). The COI gene provides precise genetic information that enables reliable species identification. Juvenile stages and eggs can also be clearly assigned to a species using this library, which may improve the efficiency and accuracy of species identification in future monitoring.
On the other hand, metabarcoding analyses are also being carried out on a trial basis as part of the project in order to evaluate the applicability of these methods for recording biodiversity in benthic habitats and to check the reference library.
Overall, this project will not only contribute to the expansion of marine biodiversity monitoring in the Baltic Sea, but also provide important insights and benefits for nature conservation, such as early detection of invasive species, long-term monitoring of biodiversity, minimal disturbance, cost efficiency, and the recording of species that are difficult to detect. The results of the project will be published in scientific publications and international databases to promote the use of the reference library in research and nature conservation.
