In the Silesian Upland (southern Poland), stands of rare mountainous plant species, i.e. Doronicum austriacum, Equisetum telmateia, and Veratrum lobelianum, were recorded close to the River Jamna and the coal mine waste tip Halemba. The species grew in two sites: semi-natural and anthropogenic ones. Soils in the anthropogenic site are more acid, with higher contents of Mg, K, Ca, and Na, but soils...
The immense variety in plant diversity at the species level might explain why it is so difficult to establish strict generalizations in vegetation dynamics. In the last two decades many published research reports have shown that the introduction of the concept of plant functional groups (PEG) into the analysis of vegetation dynamics might be more informative in explaining spatiotemporal changes of...
