Ragnar Kinzelbach hat das langjährige Projekt der zoologisch-botanischen Austauschpraktika der Moskauer und der Rostocker Universität mit der ihm eigenen Vehemenz tatkräftig unterstützt und begleitet. Zweimal nahm er am Feldpraktikum in Russland am Weißen Meer teil. In diesem Beitrag wird dieses Randmeer vorgestellt und mit der Ostsee verglichen, einschließlich der postglazialen Entwicklung. Ein bis heute noch nicht endgültig entschiedenes Thema ist die Diskussion um Glazialrelikte der Ostseefauna, die zum Teil mit dem Weißen Meer in Verbindung stehen. Es wird eine Übersicht der Fischgemeinschaft des bis in die Arktis reichenden Weißen Meeres gegeben und auf Besonderheiten verwiesen. Mit weniger als 50 marinen Fischarten, von denen nur 32 etabliert sind, ist es sehr artenarm. 23 Fischarten konnten als Belege für die Zoologische Sammlung der Rostocker Universität gesammelt werden. Zoological and botanical excursions to the White Sea – its fish community and historical connections to the Baltic Sea Abstract: With his characteristic vehemence, Ragnar Kinzelbach actively supported and accompanied the longstanding zoological-botanical students exchange project between the universities of Moscow and Rostock. Twice he participated in the field courses in Russia at the White Sea. This paper presents this marginal sea in comparison with the Baltic Sea, including the postglacial development. A topic that has not yet been conclusively resolved is the discussion of glacial relicts of the Baltic fauna, some of which are associated with the White Sea. An overview of the fish community of the White Sea, which extends into the Arctic, is given and special features are pointed out. It is a very species-poor sea, with fewer than 50 marine fish species, of which only 32 are established. 23 fish species were collected for the zoological collection of the Rostock University

Cryptic and hybridizing species may lack diagnostic taxonomic characters leaving researchers with semi-diagnostic ones. Identification based on such characters is probabilistic, the probability of correct identification depending on the species composition in a mixed population. Here we test the possibilities of applying a semi-diagnostic conchological character for distinguishing two cryptic species of blue mussels, Mytilus edulis and M. trossulus. These ecologically, stratigraphically and economically important molluscs co-occur and hybridize in many areas of the North Atlantic and the neighboring Arctic. Any cues for distinguishing them in sympatry without genotyping would save much research effort. Recently these species have been shown to statistically differ in the White Sea, where a simple character of the shell was used to distinguish two mussel morphotypes. In this paper, we analyzed the associations between morphotypes and species-specific genotypes based on an abundant material from the waters of the Kola Peninsula (White Sea, Barents Sea) and a more limited material from Norway, the Baltic Sea, Scotland and the Gulf of Maine. The performance of the “morphotype test” for species identification was formally evaluated using approaches from evidence-based medicine. Interspecific differences in the morphotype frequencies were ubiquitous and unidirectional, but their scale varied geographically (from 75% in the White Sea to 15% in the Baltic Sea). In addition, salinity-related variation of this character within M. edulis was revealed in the Arctic Barents Sea. For every studied region, we established relationships between the proportions of the morphotypes in the populations as well as between the proportions of the morphotypes in samples and the probabilities of mussels of different morphotypes being M. trossulus and M. edulis. We provide recommendations for the application of the morphotype test to mussels from unstudied contact zones and note that they may apply equally well to other taxa identified by semi-diagnostic traits.

AbstractArctic birds migrating southwards face a multitude of challenges such as habitat loss, pollution, overexploitation of food resources and climate change impacts. Long-tailed Duck winter populations in the Baltic Sea have declined in recent decades. However, precise spatial data are lacking, especially from males. Thus, we aimed to identify the wintering grounds, timing of migration and stopover sites of males and females. We studied spatiotemporal distribution patterns of eight male and five female Long-tailed Ducks using implanted ARGOS satellite transmitters. Birds were tagged in the breeding season on Kolguev Island, Russia. After the breeding period, Long-tailed Ducks from Kolguev used three main post-breeding areas: most males undertook long distance eastward post-breeding migration to areas around the Yamal and Gydan peninsulas, while one male and four females moved short to the southeast coast of Kolguev, and one female moved to Mezhdusharsky Island in the Novaya Zemlya Archipelago. Autumn migration included stopover sites in the White Sea, Lake Ladoga, the Gulf of Finland and the Gulf of Riga, and all birds except one spent the winter in the southern part of the Baltic Sea, from the Pomeranian coast and Hoburgs bank to the Gulf of Finland. Only one female stayed in the White Sea for the winter. All but one bird used the White Sea as a stopover site in May, suggesting that this area is of special importance.

AbstractThe storm events in the Baltic Sea are examined in connection with the main weather patterns grouped into the circulation types (CTs), and their changes in present climate. A calendar of storms was derived from results of wave model SWAN (Simulating WAves Nearshore) experiments for 1948-2011. Based on this calendar, a catalogue of atmospheric sea level pressure (SLP) fields was prepared for CTs from the NCEP/NCAR dataset. SLP fields were then analyzed using a pattern recognition algorithm which employed empirical orthogonal decomposition and cluster analysis. For every CT we conducted an analysis of their seasonal and interannual changes, along with their role in storm event formation. An increase of the storm CTs’ frequency in the second part of the 20th century was shown to be in a close agreement with teleconnection circulation patterns such as the Arctic Oscillation, North Atlantic Oscillation and the Scandinavian blocking.
