Opis:
The aim of the study was to determine the biological characters typical of Neomysis integer, to investigate and update issues of its biology, ecology, and distribution in the southwestern Baltic Sea, and to compare biological properties of N. integer collected during eight study seasons in 2006–2007 in the region from Świnoujście to Darłowo. No link was established between N. integer size and sample collection site. The population attained sizes within the range of 2.64 to 18.84 mm. The size at which females achieved sexual maturity varied seasonally. A mean of 34 eggs was noted in the marsupium. The mean wet weight of N. integer was 0.011 g. Three generations were confirmed at most of the study sites.

Opis:
The export of phytal material from the eutrophic Szczecin Lagoon into the Pomeranian Bay creates excellent trophic conditions for the local benthic fauna in the vicinity of the mouth of the river Świna, where the bottom macrofauna is abundant but highly variable. The changes in the bottom macrofauna biomass of selected taxa, chlorophyll a and nutrient concentrations were tested for associations. The biomasses of selected taxa varied in significant concordance, which suggests that these changes have common causes. Despite the importance of trophic enrichment to faunal abundance, no relationships between faunal biomass and chlorophyll a concentration changes were established. The presence of organic matter enables macrofauna to attain a high biomass, but population fluctuations are controlled by numerous factors. The significant relationship between the changes in the annual average phosphate levels and chlorophyll a concentrations in the Szczecin Lagoon indicates the importance of this nutrient to primary production processes in the Lagoon and to the trophic conditions for benthic macrofauna in the vicinity of the Świna mouth.

Opis:
The absorption properties of phytoplankton in surface waters of the Baltic Sea and coastal lakes are examined in the context of their relationships with the concentration of the main photosynthetic pigment, chlorophyll a. The analysis covers 425 sets of spectra of light absorption coefficients aph(l) and chlorophyll a concentrations Chla measured in 2006—2009 in various waters of the Baltic Sea (open and coastal waters, the Gulf of Gdańsk and the Pomeranian Bay, river mouths and the Szczecin Lagoon), as well as in three lakes in Pomerania, Poland (Obłęskie, Łebsko and Chotkowskie). In these waters the specific (i.e. normalized with respect to Chla) light absorption coefficient of phytoplankton aph *(l) varies over wide ranges, which differ according to wavelength. For example, aph *(440) takes values from 0.014 to 0.124 mg1 m2, but aph *(675) from 0.008 to 0.067 mg1 m2, whereby Chla ranges from 0.8 to 120 mg m3. From this analysis a mathematical description has been produced of the specific light absorption coefficient of phytoplankton aph *(l), based on which the dynamics of its variability in these waters and the absorption spectra in the 400—700 nm interval can be reconstructed with a low level of uncertainty (arithmetic statistical error: 4.09—10.21%, systematic error: 29.63—51.37%). The relationships derived here are applicable in local remote sensing algorithms used for monitoring the Baltic Sea and coastal lakes and can substantially improve the accuracy of the remotely determined optical and biogeochemical characteristics of these waters.

Opis:
This article focuses on the diatom assemblages and geochemical composition of sediment cores retrieved from the Pomeranian Bay. We also discuss similarities and differences in the diatom assemblages and the palaeogeographic development of nearby regions. Our main objective was to determine the characteristics and rate of the Littorina transgression in the Pomeranian Bay area. Sediments were divided into units based on differences in the distribution of diatom ecological groups and in geochemical ratios, such as Mg/Ca, Na/K and Fe/Mn. This study identified lacustrine sediments deposited during the time of the Ancylus Lake. This lacustrine-period sedimentation took place in a shallow lake under aerobic conditions. The record of the onset of marine environment dates to 8900–8300 cal BP and corresponds to the Littorina transgression. After about 8300 cal BP, sedimentation took place in a deeper marine environment with higher biogenic production and anaerobic conditions. The abrupt appearance of marine diatom species and increased geochemical salinity indicators reflect the large impact of the Littorina transgression on the Pomeranian Bay environment.

Opis:
Fluffy layer suspended matter (FLSM) and surface sediment samples from the Pomeranian Bay were examined for fatty acid, lipid and organic matter contents. FLSM is a several-centimetre-thick layer of fairly concentrated particulate matter lying on the sea floor significantly affecting the flux of matter to depositional basins. Analyses of fatty acids were used to establish sources and decomposition rates of labile organic matter along a transect from the shallow, highly dynamic, Odra estuary to the Arkona Basin, a deep, low energy, depositional area. In FLSM and sediments respectively, the ranges of organic matter contents were 4.0–25.0% and 5.1–23.0%, those of lipids 0.1–5.4% and 0.30–1.67%, and those of fatty acids 50–991 μg g−1 dry wt. and 100–546 μg g−1 dry wt. In shallow waters, the contents of these compounds are very variable, mirroring variations in biological activity and hydrological conditions. The high percentage of polyunsaturated fatty acids in shallow areas indicates the presence of fresh, undegraded, labile organic matter of autochthonous origin. Fatty acids, the most labile components, are transported as suspended matter attached to minerals and finally accumulated in the depositional area in the form of condensed organic macromolecules. The intensity of bacterial decomposition of organic matter in this system is reflected in the high percentage of branched fatty acids. The low fatty acid content in the organic matter is attributed to the high rate of decomposition of the labile organic matter. No linear correlation was found between the contents of fatty acids and lipids.

Opis:
The brackish water environment of the Baltic Sea is dominated by a strong gradient of salinity and along with salinity the benthic diversity decreases – salinity is regarded as the master factor regulating benthic diversity in brackish habitats. In this scheme, consistently small patches of comparatively higher or lower benthic diversity do emerge in areas where either environmental or anthropogenic impacts on the benthic habitat change drastically over short spatial distances. Hence, spatial diversity of ecological factors creates diversity among benthic colonization and community structures. We show through a logistic modeling approach the possibility to predict thereby induced benthic colonization areas and community structures inside the broad scheme of a brackish water habitat. This study bases upon quantitative macrozoobenthic abundance data collected over a period of 4 years. It clearly demonstrates the need to analyze species’ relationships in gradient systems such as the Baltic Sea and provides a tool to predict natural and anthropogenic forced changes in species distribution.

Opis:
From 1994 to 1996 changes in the concentrations of dissolved mono- (MCHO) and total dissolved polysaccharides (TCHO) as well as the activities of carbohydratedegrading enzymes (α- and β-glucosidase, glucosaminidase) were investigated during mixing of water from the River Odra and the open Pomeranian Bight. This study addresses the question of whether their distribution was a result of physical dilution alone or if biological interactions were detectable. Within the salinity gradient, ranging from 1.9 to 7.8 PSU, TCHO declined from 13.2 μmol l−1 near the Świna mouth to 2.8 μmol l−1 after mixing. Concentrations of MCHO decreased from 3.4 μmol l−1 to 1.1 μmol l−1 but its distribution pattern varied more between summer and autumn than that of TCHO. The hydrolysis rate (Hr) by glucosidase and glucosaminidase activities was reduced from 13.9% h−1 to 0.3% h−1 and 9.9% h−1 to 0.2% h−1, respectively, and correlated with the uptake rate of glucose (To) by bacteria. In summer, the To/Hr ratio increased from about 1.2 to 29.4, mainly because of stronger decreases in Hr than in To. It was shown that the relationship between enzymatic release and uptake of carbohydrates influences the concentration of dissolved carbohydrates within the salinity gradient. Most probably, the decrease in carbohydrate-degrading enzymes is the result of reduced substrate stimulation and the lower number of particle-associated bacteria.

Opis:
The contents of astaxanthin, canthaxanthin and astaxanthin esters were studied in natural populations of the copepod Acartia bifilosa from the Pomeranian Bay and Gulf of Gdańsk in the southern Baltic Sea. Samples dominated by any one of three developmental groups: (1) nauplii, (2) copepodids I–III and (3) copepodids IV–V and adults of Acartia bifilosa were analysed by means of high performance liquid chromatography (HPLC). As ontogenetic development progressed, significant changes occurred in the proportion of particular pigments in the total pigment pool of the various developmental groups. Astaxanthin and canthaxanthin occurred in all the groups, the former being clearly dominant. However, an increasing percentage of astaxanthin esters was recorded in the copepodids I–III, and even more in the copepodids IV–V and adults group. Most probably, astaxanthin is the main pigment active in copepod lipid metabolism. Carotenoid pigments in copepods very likely act as efficient free-electron quenchers and may be involved as antioxidants in rapid lipid metabolism. The exogenously feeding stages (late nauplii and copepodids) transform plant carotenoids taken from food and are evidently capable of metabolising astaxanthin by esterification and further degradation. It is emphasised that, according to literature data, astaxanthin esters may have an even higher quenching ability. It is suggested that crustacean carotenoid pigments, with their electron donor-acceptor abilities, may replace oxygen in peroxidation processes connected with lipid metabolism. The consequences of such a physiological role of astaxanthin for present-day estimations of energy balances in zooplankton communities are mentioned.
