Phytosociological Relevés

Non-forest communities in the western part of the Kampinos National Park were studied in the years 1991 – 1998 with regard to their phytosociological diversity and dynamic processes currently underway in them. A total of 323 phytosociological releves were prepared by the widely used method of Braun-Blanquet. These releves served as basis for identification of 31 associations and 7 meadow and sedge communities of undetermined level. 15 syntaxa were recorded in the <em>Phragmitetea</em> class, 18 syntaxa – in the <em>Molinio-Arrhenatheretea</em> class, 2 associations in the <em>Scheuchzerio-Caricetea</em> class, as well as 3 grassland associations from <em>Koelerio glaucae-Corynephoretea canescentis</em> and <em>Nardo-Callunetea</em> classes. In order to determine the character and direction of changes in phytocoenoses, 4 basic ecological processes have been distinguished – fluctuation, degeneration, regeneration and secondary succession. Within secondary succession, recreative, creative and anthropogenically forced secondary succession were distinguished.

Abstract Results of research on the process of spontaneous overgrowth of subalpine forest glades in the Gorce National Park are presented in the paper. Research was carried out in 2006-2008. The condition and directions of changes of glades undergoing conservation efforts of different intensity were examined.

Although the general ultrastructure of Cyanidium caldarium, an acidophilic, thermophilic alga of questionable taxonomic rank, has been extensively studied (see review of literature in reference 1), some peculiar ultrastructural features of the chloroplast of this alga have not been noted by other investigators.Cells were collected and prepared for thin sections at the Yellowstone National Park and were also grown in laboratory cultures (45-52°C; pH 2-5). Fixation (glutaraldehyde-osmium), dehydration (ethanol), and embedding (Epon 812) were accomplished by standard methods. Replicas of frozenfracture d- etched cells were obtained in a Balzers apparatus. In addition, cells were examined after disruption in a French Press.
