Spatial Aggregation and Biometric Variability of the Grass (L.) Roth during Different Expansion Stages in Mesic Mountain Meadows.

(L.) Roth is one of the most expansive clonal grass species. Despite many publications about its biology, the expansive mechanism of is relatively unknown.

Dependence of the Distribution and Structure of the White Mulberry () Population in Wrocław on the Intensity of Anthropopressure and Thermal Conditions.

The selection of species which show the highest possible tolerance to negative habitat conditions, also among plants of foreign origin, is a pressing issue. One of the species we would like to recommend for planting in urban areas is the white mulberry species ( due to both its outstanding adaptability and its ecosystem services. There are no reliable studies on the distribution of this species in urbanized areas in Poland, nor sufficient analyses of the methods of its renewal, both deliberate and spontaneous spread through self-seeding.

The effect of abandonment on vegetation composition and soil properties in Molinion meadows (SW Poland).

Intermittently wet meadows of the Molinion alliance, as with many other grasslands of high-nature value, have become increasingly exposed to abandonment due to their low economic value. The potential consequences of land abandonment are the decrease in species diversity and environmental alterations. The issue of land-use induced changes in plant species composition and soil physico-chemical parameters have been rarely studied in species-rich intermittently wet grasslands.
