    Description: The region of the Filchner Outflow System (FOS) in the southeastern Weddell Sea is characterized by intensive and complex interactions of different water masses. Dense Ice Shelf Water (ISW) emerging from beneath the ice shelf cavities on the continental shelf, meets Modified Warm Deep Water (MWDW) originating from the Antarctic Circumpolar Current at the sill of the Filchner Trough. These hydrographic features convert the FOS into an oceanographic key region, which may also show enhanced biological productivity and corresponding aggregations of marine top predators. In this context, six adult Weddell seals (Leptonychotes weddellii) were instrumented with CTD-combined satellite relay data loggers in austral summer 2014. By means of these long-term data loggers we aimed at investigating the influence of environmental conditions on the seals' foraging behaviour throughout seasons, focussing on the local oceanographic features. Weddell seals performed pelagic and demersal dives, mainly on the continental shelf, where they presumably exploited the abundant bentho-pelagic fish fauna. Diurnal and seasonal variations in light availability affected foraging activities. MWDW was associated with increased foraging effort. However, we observed differences in movements and habitat use between two different groups of Weddell seals. Seals tagged in the pack ice of the FOS focussed their foraging activities to the western and, partly, eastern flank of the Filchner Trough, which coincides with inflow pathways of MWDW. In contrast, Weddell seals tagged on the coastal fast ice exhibited typical central-place foraging and utilized resources close to their colony. High foraging effort in MWDW and high utilization of areas associated with an inflow of MWDW raise questions on the underlying biological features. This emphasizes the importance of further interdisciplinary ecological investigations in the near future, as the FOS may soon be impacted by predicted climatic changes.

    In:  Supplement to: Jungblut, Simon; Beermann, Jan; Boos, Karin; Saborowski, Reinhard; Hagen, Wilhelm (2017): Population development of the invasive crab Hemigrapsus sanguineus (De Haan, 1853) and its potential native competitor Carcinus maenas (Linnaeus, 1758) at Helgoland (North Sea) between 2009 and 2014. Aquatic Invasions, 12(1), 85-96, https://doi.org/10.3391/ai.2017.12.1.09

    Description: The Asian shore crab Hemigrapsus sanguineus (De Haan, 1853) has recently established populations in the North Sea and now occurs within the native ranges of the green crab Carcinus maenas (Linnaeus, 1758). To determine potential competitive effects and to assess the progress of the invasion, species-specific population characteristics (numerical abundances, biomasses, and size distributions) of the two species around the island of Helgoland (German Bight, southern North Sea) were compared for surveys conducted in 2009 and 2014. Sampling sites were chosen based on accessibility and differed in their topography and wave exposure, which allowed testing for the influence of these factors on the establishment success of H. sanguineus. The numerical abundance and biomass of H. sanguineus increased markedly and approached those of C. maenas in 2014. At a sheltered site, H. sanguineus even outnumbered C. maenas, whereas the converse was observed at a site exposed to strong winds and waves. Although such contrasting abundance patterns between the native and the introduced shore crab may be the result of direct interference, the dominance of H. sanguineus at the sheltered site may also be explained by enhanced larval settling rates caused by odors of conspecifics. The results suggest that the invasion of H. sanguineus has not yet reached its equilibrium, and population abundances in the North Sea are expected to further increase in the future.

    Description: The Asian shore crab Hemigrapsus sanguineus and its congener, the Asian brush-clawed crab H. takanoi, were first found in Europe in 1999 and 1994, respectively. Hemigrapsus sanguineus was initially detected in Le Havre (France) and in the Oosterschelde (The Netherlands). Now it occurs from northern France to the German Wadden Sea. Hemigrapsus takanoi was originally found in La Rochelle (France) and is now established from the Bay of Biscay to the German Wadden Sea. In 2014, a Baltic Sea population was detected in Kiel Fjord (Germany), most likely introduced via the Kiel Canal. Here we summarize the most recent findings on the northern expansion of H. sanguineus and H. takanoi and their competition with the native counterpart, the green shore crab Carcinus maenas. Two population studies in the intertidal areas around the rocky island of Helgoland and the Wadden Sea island of Sylt (Germany) revealed that the three species favor different levels of wave exposure. Our studies presented the highest densities of Hemigrapsus spp. in Europe so far with 144 H. sanguineus m-2 on Helgoland, and more than 200 ind. m-2 of either species on Sylt. The Baltic population of H. takanoi is increasing in Kiel Fjord and adjacent bays. Individuals of H. takanoi were recently found in Wismar Bay, further east along the Baltic coast. In the framework of a citizen-science project, specimen of both species were found at the Swedish west coast, representing the northernmost records in Europe so far. The success of established populations and the continuous extension of the distribution areas suggest that the presence and impact of both Hemigrapsus species on European coasts will significantly increase in the future.

    Description: Metabolic regulation, control of gene expression or the evolutionary origin of new proteins are examples of biochemical adaptations that allow organisms to survive within a wide spectrum of environmental conditions. The North Sea shrimp Crangon crangon has high reproduction rates. It is an opportunistic feeder and shows to be well adapted to heterogeneous and variable environmental conditions. Previous studies revealed unusual expression patterns and isoforms of digestive enzymes with a high variability between individuals and between seasons. Such a pronounced variability is not common in other decapod species. The unspecific feeding habits of C. crangon can be seen as an adaptation to a variable environment. This may be supported by the heterogeneity of digestive endopeptidases due to the variability of food sources. Previous studies showed protein polymorphism as a phase in molecular evolution. It represents the first step in the long‐lasting establishment of mutations within populations. The reasons for the unusual heterogeneity of digestive enzymes in C. crangon are not yet clear, but a better understanding of this phenomenon can help to explain the extraordinary performance of C. crangon in a highly variable environment. We obtained the transcriptome of midgut gland tissue from C. crangon, which we used as a basis for gene expression analyses. Additionally, the obtained sequences were analysed for isoforms of the key digestive enzymes. First results indicate that the expression of digestive enzymes in C. crangon follow a similar pattern as previously seen in enzyme activities. Cysteine proteinases seem to have more isoforms participating in the extracellular digestion than serine proteinases. This approach will help to better understand processes that modulate the unique expression pattern of digestive enzymes and biochemical strategies that allow this species to exist in a very variable environment.
