Plant-soil feedback and its interactions with other factors determining plant coexistence
Opravilová, Tereza ; Kuťáková, Eliška (advisor) ; Čuda, Jan (referee)
Plant-soil feedback has been a well-studied mechanism in recent years of the success of invasive plants, the shift of species in succession, and the structure of plant communities in general. It is a process during which the plant affects the soil with its growth and these changes are reflected in the growth of other plants. Despite the large number of previous studies, relatively little attention is paid to the interaction of plant-soil feedback with other factors, which I consider important for understanding its role in natural plant communities. The aim of the work was to clarify the influence of plant-soil feedback on model species Arrhenatherum elatius and Centaurea scabiosa and to compare its influence with other factors - interspecific competition and herbivory (simulated loss of aboveground biomass). The influence of factors was investigated using biomass and changes in plant physiology, specifically chlorophyll fluorescence and the content of elements in aboveground biomass. The plant-soil feedback mechanism of the model species was assessed using the content of elements in the soil after cultivation. In the biomass of the species Arrhenatherum elatius, the factors of plant-soil feedback and competition manifested themselves in mutual interaction, when the presence of a competitor changed...

Plant-soil feedback and locality management as factors determining vegetation development
Opravilová, Tereza ; Kuťáková, Eliška (advisor) ; Mayerová, Hana (referee)
Places disturbed by the mining of minerals occupy a substantial part of the Earth's surface. Together with the abandonment of these sites after the mining process, the issue of the restoration of plant communities is addressed. One way of such recovery is spontaneous succession. This is influenced by many factors, including plant-soil feedback, the indirect interactions among plants mediated by soil environment, thanks to which succession can be slowed or accelerated. If we want to preserve a certain grassland community in places of restored spontaneous succession, it is advisable to introduce some management methods at the site. These are usually mowing or pasturing. This work summarizes the knowledge about plant- soil feedback, succession in quarries, various management methods and their impact on plant communities. It serves as a theoretical basis for my diploma thesis on the model site of the Čeřinka quarry in the Czech Karst where I plan to observe the influence of grazing on the plant community by phytosociological relevés, and, using experiments, to observe the mutual influence of plant-soil feedback and grazing on plant growth.
