Intraspecific trait variability of plants in the succession on the Sokolov post-mining sites.
Říhová, Eva ; Mudrák, Ondřej (advisor) ; Lisner, Aleš (referee)
In primary succession, the colonization of plants is essential for the development of the ecosystem. Plants colonizing a disturbed site face a number of limiting factors, such as the adverse chemical and physical conditions of the substrate. In general, primary succession follows a trend of development from an unfavorable substrate to a substrate with available nutrients and water. Sokolov post-mining sites are an exception. Previous studies showed that in intermediate parts of the succession, plants should be the most limited by water, due to the formation of amorphous clay, which adhesively binds water. One of the ways how to determine the main limiting factors of plants and verify these assumptions is to study plant functional traits. The intraspecific shifts in functional traits during the succession may show how the plant environment changes for plants. In this thesis I have measured functional traits (plant height, specific leaf area, leaf area and leaf mass) of three species (Calamagrostis epigejos, Fragaria vesca, Tussilago farfara) at three spontaneously developing localities of Sokolov post-mining sites differing in age since heaping (2, 31, and 56 years). The intraspecific trait variability showed that the most limiting conditions for plant growth are at locality of intermediate age....
