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]

The beetle fauna of a small inland waterbody on the southern outskirts of Greifswald in Western Pomerania, Germany (54°03'48.3 "N 13°22'41.4 "E) was studied from 2019 to 2022. This small waterbody is for the first time named as Greifensoll and described. Hydrologically, the Greifensoll is characterized by seasonal water level fluctuations with irregular summer drying out. The vegetation of the waterbody is dominated by large populations of broadleaved cattail (Typha latifolia L.) and great yellowcress (Rorippa amphibia (L.) Besser). Most frequently applied collecting methods were collecting by hand and catching aquatic beetles with kitchen strainer and water net. A total of 204 species were recorded, among them 82 species of aquatic beetles from nine families and 101 species of terrestrial beetles from twelve families, including 21 species of Steninae (Staphylinidae). Noteworthy are records of the endangered diving beetle species Agabus labiatus (Brahm, 1790), Graptodytes bilineatus (Sturm, 1835), Hydroporus fuscipennis Schaum, 1868 and Rhantus bistriatus (Bergsträsser, 1778), of the longtoed water beetle Dryops griseus (Erichson, 1847), and the rove beetles Stenus melanarius Stephens, 1833 and S. sylvester Erichson, 1839. For the Federal State of Mecklenburg-Western Pomerania, the silken fungus beetle Telmatophilus sparganii (Ahrens, 1812) is reported for the second time ever, and the tooth-nosed snout weevil Temnocerus coeruleus (Fabricius, 1798) for the first time after the year 2000. With its high species richness, the Greifensoll represents a locally important habitat in an intensively used agricultural landscape. [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.

As part of two revitalization projects of coastal wetlands on the Western Pomerania lagoon coast, dikes of the polders Bresewitz and Drammendorf are planned to be dismantled. These projects were accompanied by faunistic studies of ground beetles. In each of the polders, carabid beetle associations were investigated in six different habitats using pitfall trapping and hand collecting methods. Remains of natural wetland in the siltation zone outside the polders were also studied. The aim of the study was to record the current state of the associations, as this serves as a data basis for documenting future changes after the implementation of the revitalization measures. The sampling includes a total of 7961 specimens in 110 species. Occurrences of two species within the studied polders are of particular interest for the fauna of Mecklenburg-Western Pomerania, Amara kulti Fassati, 1947 (both study areas), and Amara strenua Zimmermann, 1832 (polder Drammendorf, areas only 0.3 m above mean-water level). The results of the investigation confirm the particular importance of the still existing dike foreland, in particular broader zones with intact siltation structure. The siltation zone represents an essential recreational potential for carabid associations of the revitalized wetlands. In contrast, ground beetle associations of the diked areas are mostly atypical with respect to coastal wetlands and mostly poor in species, as they are characteristic of the intensively used agricultural landscape. The main reasons for this presumably are the leveled soil moisture situation and vegetation structure. It is therefore recommended to include marginal remains of natural wetland areas in the overall projection of planned dike dismantling projects in the future. [ABSTRACT FROM AUTHOR]

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.

Records of 106 species of rove beetles in Mecklenburg-Vorpommern (MV) from the periods 1987 to 1990 and 2014 to 2018 are documented and discussed. Three species are new to the fauna of the federal state: Atheta sequanica (Brisout de Barneville, 1860), Phloeopora nitidiventris Fauvel, 1900, and Carpelimus schneideri (Ganglbauer, 1895). Being attended by climate change, considerable changes in beetle fauna, which are difficult to diagnose, are most likely to be expected also in MV. For example, the winterly air temperature in the area has increased linearly over 138 years (1881-2018), and much more rapidly since the mid 1980s. Concurrently, the amount of winterly precipitation has increased from 89 mm (1881-1890) to 142 mm (2008-2017). These distinctly perceptible changes certainly have consequences also on overwintering and winter-active species of rove beetles. It is advisable to intentionally extend collecting activities onto winter season in order to register potential changes in fauna, whose causes are in the cold months. [ABSTRACT FROM AUTHOR]

The current volume 59 of the Archive for Nature and Regional Studies Mecklenburg-Vorpommern is now accessible to everyone via open access. This allows interested individuals to read the contributions more easily. The volume contains articles on the regional fauna and flora, particularly focusing on beetles. It also presents a book on the history and nature of the Riether Werder as well as new species of rove beetles. The publication of primary data from a teaching event is also demonstrated.

Volume 57 of the Archive for Nature and Regional Studies Mecklenburg-Vorpommern is now available in print. It contains seven contributions to regional research, including three on lichens and two on rove beetles. The articles cover topics such as changes in lichen flora in Rostock, the examination of lichen specimens from 1902, and a lichen collection from Antarctica. Additionally, new species of rove beetles are introduced, and the ground beetle communities on the Vorpommern Bodden Coast are analyzed. The work of the Malacology Working Group reports on a mapping project in the vicinity of Lake Galenbeck. [Extracted from the article]
