New Syntaxa

The paper characterizes the 3 associations comprising plant communities with Sphagnum rubellum in the south-eastern part of the Baltic region. The new syntaxa differ from each other both in their floristic characters and the pronounced affinity to definite regional mire types and particular habitats. The ass. Drosero-Sphagnetum rubelli is typical of the relatively most thorough ranges. It is observed from the Kaliningrad region to the Karelian Isthmus and, according to the published reference, occurs even throughout the whole area around the Baltic Sea. Its most typical habitat is that of margins of mire lakes and pools. The ass. Eriophoro-Sphagnetum rubelli occurs in central plateaus of convex plateau-like bogs, typical of the areas adjacent to the Baltic Sea coast. It occupies extended flat mire ecotopes with the water level 0.2–0.25 m deep. The ass. Empetro-Sphagnetum rubelli is characteristic of the retrogressive complex in the convex bogs of the East-Baltic Province. It is mostly observed along the coast of the Gulf of Finland. Its stands are rather dynamic and unstable in both space and time. The presence of communities comprised by these 3 associations is an important vegetation character of the series of regional mire types. Assuming an association level of the respective syntaxa seems rational for the purposes of adequate reflection of plant cover diversity.

The sediment sampling from different areas of the beaches in the south-eastern part of the Baltic Sea (in Kaliningrad region) was executed for the purpose of studying the quantitative and qualitative composition of the microplastics particles (range 0.5-5 mm). Preference is given to those beaches that are exposed to maximum anthropogenic pollution. From June, 2015 to January, 2016, there were 14 expeditions along the coastline of the Baltic Sea (in Kaliningrad region) to collect experimental materials. The majority of samples were collected on the most recent flotsam deposited at “wracklines”, in the supralittoral zone. The primary examination of those samples revealed the presence of abundant microplastic particles of the required size range (0.5-5 mm). Quantitative distribution of microplastics in beach sediments was obtained in milligrams per gram of sediment and milligrams per m2: on average 0.05-2.89 (mg per gram of sediment) and 370-7330 (mg per m2), accordingly.

We show that Fennoscandia was invaded in the Holocene by three distinct mitochondrial lineages of Natrix natrix. Two of these lineages arrived from the south, and one from the east. One of the ‘southern lineages’ is confined to Gotland, where also the second ‘southern lineage’ is found. The latter is widely distributed in the southwestern Baltic region, western Fennoscandia and on the Åland Islands, while the other lineage present on Gotland is only known from a few sites in the Baltic region. In addition, we recorded a third mitochondrial lineage in southern continental Finland, which was previously unknown from Fennoscandia. This lineage also occurs in the southeastern Baltic region and further east, suggesting that southern Finland was colonized from the east. Thus, the phylogeography of N. natrix matches a general paradigm for Fennoscandia, with Holocene invasions from the south and east.

The study of paleogeography of lakes is an actual and important direction in modern science. As part of the study of lakes in the North-West of the Karelian Isthmus, this analysis will establish the dynamics of salinity of objects, which will allow to reconstruct changes in the level of the Baltic Sea in the Holocene.

Palaeoenvironmental Changes

Holocene diatom biostratigraphy of the SW Gulf of Gdańsk, Southern Baltic Sea (part III)The palaeoenvironmental changes of the south-western part of the Gulf of Gdańsk during the last 8,000 years, with reference to the stages of the Baltic Sea, were reconstructed. Diatom analyses of two cores taken from the shallower and deeper parts of the basin enabled the conclusion to be drawn that the microflora studied developed in the three Baltic phases: Mastogloia, Littorina and Post-Littorina. Moreover, the so-called anthropogenic assemblage was observed in subbottom sediments of the study area.

Science And Research

The aim of the article is to demonstrate how science and researchcooperation may help to reintegrate the Baltic region in the 21st century withthe participation of Russia. This is done through the analysis of documentsand strategies of Baltic Sea regionalism in the context of the regional knowledgeregime. Attention is paid to different positionalities of the regional actorsand their narratives. The theoretical framework is secured by an analysis ofcritical junctures drawing on case studies from the years 1989-91 and 2014 andthe subsequent reconfiguration of the power / knowledge nexus. The analysisshows that this reconfiguration actively contributes to creating and changingthe content and context of the Baltic Sea regionalism as based on new symbolic,economic, and political capitals. The conclusion points to the potentialof Russia’s involvement in the co-creation of the regional knowledge regimeand defines the conditions and methods of possible cooperation.

The present study area is located within the south–eastern segment of the Baltic Sea framed by 55o30’–56o30’ N and 19o00’–21o15’E. The area is re-visited with the aim to describe in more detail the geologic prerequisite and development of the palaeo–incisions as well as the timing of their subsequent infillings. The channels form distinctive features in the sedimentary bedrock along the outer limits of pre–Weichselian ice sheets, on average reaching depths into the bedrock of 50 m in the nearshore zone of Lithuania to 100 m along the slope to the Gotland depression in the west. The development of palaeo–incisions systems is governed by the easily eroded late Palaeozoic to Mesozoic bedrock of the present area. Only rare ocurrences of channels have been reported from the middle and lower parts of the Palaeozoic further west in the Baltic Sea. The present investigation supports a mechanism that the channels formed below the ice near the ice sheet margin by melt water erosion under high pressure. The channels start at random where a fracture in the ice develops forming outlet of water contained below the central part of the ice sheet. The channels often merge together in the direction of the ice margin, possibly gradually adapting to previous fracture systems in the bedrock. The investigated incisions were infilled prior to the advance of the Weichselian ice sheet and some have been reopened and repeatedly infilled.
