Plant response to changes in disturbance magnitude

In this thesis, I investigate plant performance in semi-natural grasslands, in order to be able to predict species composition after a change in management (from mowing to rototilling). Empirical studies were done at two different levels. On the community level population response due to a change in management is presented without explaining the underlying processes. Although investigations into the regeneration potential of all characteristic semi-natural grassland species can account for plant community response after disturbance, only life-cycle analysis for individual species, based on the observations of individuals within that species, can link population dynamics and environmental factors and hence provide useful insights into the underlying pattern and mechanisms. In this study, plant response of focal species after disturbance is extrapolated in time using simulation models, and population survival/extinction is forecasted for given disturbance return intervals.
