The effect of different habitat conditions on temporal and spatial variation in selected population properties of the rare plant species Trollius europaeus L.

The investigations presented here were carried out in years 2013-14, in a Molinietumcaeruleae meadow with inter-rupted plant cover caused by animal activity (patch I); abandoned Molinietumcaeruleae meadows with untouched plant canopy, dominated by species with considerable height of the above-ground parts (patches II-VI); as well as the edge (patch VII) and the interior (patch VIII) of abirch woodlot. The height of standing vegetation and soil moisture increased in subsequent patches, whereas the light availability at ground level showed inverse tendency. The abundance of Trolliuseuropaeus subpopulations in all studied patches was rather low. In patch I, juvenile individuals dominated, while in other stands - flowering adults pre-vailed. The lack of temporal variability in the number of basal leaves observed in patches III, IV, V, VI and VII might be due to lack of available area necessary for clonal proliferation of ramets, while the increase of basal leaves number in other sites might suggest unlimited iterative growth. The dimensions of basal leaves in consecutive years were constant in majority of subpopulations, while they showed strong spatial variability increasing gradually from patch I to patch VII and, subsequently, decreasing in patch VIII. The substantial dimensions of basal leaves may enable better light capture in sites with great level of lateral shade, while smaller dimensions in patches located within a woodlot may be due to shade from above created by trees. Lack of temporal variability and presence of substantial spatial variability in the number and height of generative stems, as well as flower production might enhance chances for successful pollination in a competitive environment. Significant changes of follicle number in time and space suggest successful process of pollination in all patches excluding patch VIII. The weak condition of the ramet clusters in patch I is not compensated by considerable seedling recruitment, whereas the satisfactory state of the ramet clusters in patches II-VIII may not suffice for the long-term maintenance of populations in colonized areas

The genus Alchemilla in the Beskid Niski Mts

The paper presents information on Alchemilla species occurring in the Beskid Niski Mts. Herbarium specimens collected from 1988 to 2013 and published data records were used to prepare this study. Distribution of each species is shown in the map, whereas appendix contains complete list of localities

List of vascular plants of the Gorce National Park

The paper presents current list of vascular plants of the Gorce National Park (the Gorce Mts, Western Car-pathians). It is based on previous publications, unpublished data available in the GPN archive and field investiga-tions carried out mainly in the years 2013–2014. The list contains 586 native species and established anthropophy-tes, including 65 species new to the Park. Moreover, information about 37 non-established and cultivated species as well as 38 species, which occurrence in the GPN is not certain, is also given

Area changes of the plant communities in chosen post-agricultural regions within Jaszcze and Jamne valleys in Gorce Mts (Western Carpathians) during the last 50 years

The paper contains results of the vegetation mapping of two areas within the Jaszcze and Jamne stream valleys in the Gorce Mts (Polish Western Carpathians), which were compared with a phytosociological map constructed in the 1960’s. Significant area changes of different plant communities were illustrated on vegetation maps and in tables. The causes of vegetation changes were also discussed

Orchis ustulata (Orchidaceae) rediscovered in the Gorce Mts (Western Carpathians)

The paper presents new localities of Orchis ustulata found in the Gorce Mts in the years 2012–2013. The distribution of this orchid within the Polish Carpathians, as well as its habitats in Gorce Mts are presented. The best methods of protecting this species were also widely discussed
