Preliminary study on the unusual properties in the habitat of Ranunculetum baudotii in Central Europe
2011
Abstract The study examines the patches of the saltwater association Ranunculetum baudotii in a new, atypical site; i.e., located more than 400 km away from the Baltic coastal line. They were found in a karst spring, and were the first locality of the community identified in Poland. The water and sediments within the patches were analyzed chemically in the laboratory, but, conductivity, water temperature and O2 content were measured in the field. The spring was determined to be a relatively stable aquatic habitat, with a typical chemical composition of subterranean water (a prevalence of hydro-carbonate, calcium and magnesium ions), and rich, e.g., in nitrogen and phosphorus, and disturbed …
The Impact of Grain Size Composition and Organic Matter Content on Magnetic Susceptibility of Anthropogenically Transformed Bottom Sediments, as Exem…
2018
The article presents the results of an analysis of the surface layer of bottom sediments in the naval harbour in Hel. During field work conducted in June 2013, 54 sediment samples were collected. The aim of the study was to examine magnetic susceptibility of harbour sediment as a parameter determining the degree of anthropopressure. As part of laboratory tests, grain size analysis was performed in order to determine organic matter content and magnetic susceptibility of the sediment. The study also measured the impact of environmental factors on fluctuations in the other studied parameters. The results demonstrate increased dynamics of sedimentary environment in the open part of the naval ha…
Ocena zagrożeń obszarów Natura 2000 w województwie opolskim na podstawie struktury użytkowania terenu
2017
Dokonano oceny zagrożeń obszarów Natura 2000 ustanowionych na obszarze województwa opolskiego. Analizie poddano struktury użytkowania gruntów i pokrycia terenu 23 znajdujących się tam obszarów. Określono także potencjalny wpływ otoczenia, wyznaczając buforowe strefy oddziaływania, dla których także zbadano strukturę użytkowania i pokrycia terenu. Określono wskaźnik antropogenizacji obszarów uwzględniający podział na formy o charakterze naturalnym i seminaturalnym oraz antropogenicznym. Wskazano główne zagrożenia dla obszarów Natura 2000 województwa opolskiego. Z przeprowadzonych badań wynika, iż tereny te mają charakter w większości naturalny i seminaturalny. Głównym zagrożeniem dla tych ob…
