Geological mapping works, conducted on 1:50,000 litho-petrographic map sheets of the South Baltic coast and the eastern part of the Pomerania Lakeland, show a clear relationship between large landforms of this area, like: subglacial channels, Wieżyca Hill, the ice lobe that accumulated Gardno moraine deposits, and sub-Quaternary relief. These landforms came into existence as a result of reactivation of pre-existing fault zones in the sub-Cainozoic basement, due to the ice mass loading during successive Pleistocene ice-sheet advances. Subglacial channels developed and thick tills and ice-dammed lake deposits were accumulated in the region. The subglacial channels and morainic belts are now dominating landforms in the Pomeranian Lakeland. Source

The paper presents electrospinning technology used for the production of polymer nanofibrous mats. Surface properties of polymer nanofibrous mats electrospun from poly (vinylidene fluoride) (PVDF) and poly (vinyl chloride) (PVC), and modified in dielectric barrier discharge (DBD) are presented. The contact angle of the polymer mats un-modified and modified in DBD generated plasma were compared. The plasma modification decreased the contact angle for water from 134° to 40°, for PVDF, and close to zero in the case of PVC. It was also observed that the contact angle decreased with an increase in the discharge power and discharge time, leading to an improvement of adhesion properties of the mat. Source

Floristic, phytosociological and hydrochemical inves-tigations were performed in 16 spring complexes of the Pomeranian rivers (northern Poland) in years 2006-2007. The aim of the study was to reveal the level of iron and manganese ion concentrations in ground water outflows and to assess their influence on vegetation diversity. Spring wa-ters contained low concentrations of Fe and Mn. Iron con-tent in 73 cases was below 1 mg dm -3. In 26 cases it ex-ceeded 1 mg dm -3 and ranged from 1.007 to 9.540 mg dm -3. The average iron content amounted to 1.262 mg dm -3. The concentration of Mn in 59 cases was lower than 0.1 mg dm -3. Higher manganese content was observed at 34 sites and it ranged from 0.104 do 0.954 mg dm -3. In 7 cases the ob-tained Mn concentration exceeded 1 mg dm -3 (1.131 -5.150 mg dm -3). The average manganese content was at the level of 0.302 mg dm -3. On the basis of 100 phytosociologi-cal pictures we distinguished 8 spring communities of Mon-tio-Cardaminetea class, 2 spring moss communities of Fon-tinaletea antipyreticae class and 5 flowing-waters phyto-coenoses of Phragmitetea class. The observed vegetation contained 89 plants species, including 66 vascular plants, 14 moss species and 6 hepatic species. Redundancy analy-sis (RDA) revealed, that Glyceria nemoralis and Carex remota tolerated high concentrations of iron and manga-nese. Brachythecium rivulare preferred lower, but also rela-tively high Fe and Mn contents. Agrostis stolonifera turned out to prefer higher concentration of iron than manganese, opposite to Palustriella commutata. Hepatic species Pel-lia endiviifolia was abundant at low contents of the ana-lysed ions. Relatively low Fe and Mn concentrations were preferred by Cardamine amara and Cratoneuron filicinum. RDA analysis of plant communities indicated that Glyc-erietum nemoralis-plicatae and Agrostis stolonifera oc-curred under high contents of iron and manganese. Rela-tively high Fe concentration favoured communities Carda-mino-Beruletum erecti and Porella platyphylla. In turn, communities Pellia endiviifolia and Palustriella commu-tata were abundant at low contents of the studied ions. The remaining plant species and communities preferred moderate levels of Fe and Mn concentrations. © by PSP. Source

In this paper the effects of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn) accumulation in submerged reed shoots on the periphyton structure in the shallow-water zone of the Vistula Lagoon (Polish internal seawaters) are discussed. Concentrations of the analysed chemical elements were determined with flame atomic absorption spectrome-try. The highest Pearson's correlation coefficients (p<0.05) were observed for Cd and Co, Ni and Cr, Pb and Cd, Pb and Co, Zn and Ni. Among periphyton, linear relation-ships occurred between sedimentators and epiphytic algae (phytoperiphyton). In order to reveal the influence of substrate chemical composition on the qualitative and quantitative composi-tion of periphyton overgrowing reed shoots, ordination methods were applied (principal component analysis PCA, canonical correspondence analysis CCA, detrended corre-spondence analysis DCA, redundancy analysis RDA). The results showed, that sedimentators (Peritricha, Rotatoria) and Nematoda preferred reed substrate with relatively high content of Mn, Co, Cu and Cd. Similar situation was ob-served for Chironomidae larvae, but additionally they used to choose substrate with low concentration of Ni and Cr. In turn, higher content of nickel and chromium favoured Cyclopoida and Harpacticoida. © by PSP. Source

This paper presents a study on a chemical variation of Pertusaria flavida in Poland. Six chemotypes were determined in the studied material, of which chemotypes IV, V and VI were never reported before. All of them produce thiophaninic acid as the diagnostic metabolite for the species and this is the only major substance in chemotype I. Chemotype II contains in addition also 2'-O-methylperlatolic acid (± confluentic acid), whereas chemotype III stictic acid complex (± minor or trace amounts of norstictic acid). Chemotype IV is characterized by the presence of 2'-O-methylperlatolic acid and stictic acid complex (± norstictic acid in minor to trace amounts). Chemotype V produce norstictic acid as a major additional substance and chemotype VI contains 2'-O-methylperlatolic acid together with norstictic acid. Chemotype II was the most common chemotype (c.75 % of specimens) in studied material. Distribution maps are presented for all chemotypes. Source
