Why do certain plants grow on certain habitats and not on others? What are the causes for floristic differences between plant communities? If these questions are asked for “normal”, i. e., relatively species rich constant natural or seminatural plant communities (more than 10–20 phanerogams) and if no single extreme, e. g., climatic or toxic factor or human interference occurs, the answers are whole constellations of factors (see, e. g., Billings 1974, p. 26). Then a further question arises. Which is the most important factor? In general, single factors on the ecophysiological level are sought, i. e., factors acting directly (immediately) on the plant, like for example aluminum-ion content of the soil, frost, drought, trampling, browsing etc.
