As part of the module "Species Knowledge and Taxonomy" of the Master's program in Integrative Zoology at the University of Rostock, field work was conducted on the coast and its hinterland of the southern Lübeck Bay in northwestern Mecklenburg-West Pomerania and on the Priwall peninsula (Schleswig-Holstein), from July 10 to 14, 2023. Species from different arthropod groups were recorded in the field or caught using different collecting methods and then identified with the help of experts in the respective species groups. A total of 379 arthropod species were identified and listed in this report, and the locations examined are briefly presented using characteristic species. Occurrences of some faunistically particularly interesting and endangered species of insects have been encountered, especially of ground and rove beetles (Carabidae, Staphylinidae), aculeates (Aculeta) and nocturnal butterflies (Lepidoptera). The results show that a teaching excursion focusing on species knowledge and biodiversity recording can provide valuable contributions to an exploration of local fauna. [ABSTRACT FROM AUTHOR]

Records of 108 species of rove beetles in Mecklenburg-Western Pomerania (MV) from 2005 to 2022 are documented. The findings focus on the south-eastern part of the state, the Löcknitz-Pekun district, which has only been marginally studied so far. Myrmecophilous species as well as Phyllodrepa melis Hansen, 1940, which is bound to badger's burrows, are described in more detail. Furthermore, the following species are reported for the first time to occur in MV and are treated in more detail: Tychus normandi Jeanell, 1950, Bledius spectabilis Kraatz, 1857, Paederus balcanicus Koch, 1938 and Erichsonius subopacus (Hochhuth, 1851). Especially nutrient-poor sandy pioneer sites in MV need to be comprehensively protected. Regardless of whether the sites are dry (heath, gravel pit, steep banks) or moist to wet (lakeshore, gravel pit, seashore), they harbour a number of rare species or species worthy of protection.

In Mecklenburg-Western Pomerania, 80 species of rove beetles were recorded between 1992 and 2020. Distribution and abundance of various species are discussed. Five species are new to the fauna of the federal state: Atheta aquatilis (Thomson, 1867), A. clientula (Erichson, 1839), A. sodermani Bernhauer, 1931, Paederus caligatus (Erichson, 1840) and Xantholinus elegans (Olivier, 1795). For selected rare species, the community of accompanying species is characterized from sieve samples of most varied habitats or structures. A comparison of the species inventory proves the ecological value of wet to dry habitats, and shows the effort that needs to be made to register both the current species inventory of the area and its changes in time. The complexity of this task lies, on the one hand, in an expansion of the range of species and, on the other hand, in a simultaneous disappearance of species, mainly caused by the loss of various habitat types.
