Impacts of hemiparasitic plants on the vegetation and biogeochemical cycling in two contrasting semi-natural grassland types
… a key role in the conservation of species-rich semi-natural grasslands. They can alter plant community composition and diversity by both parasitism and litter effects. The drainage of resources by the hemiparasite suppresses preferred host species to the benefit of non-host species. On the other …

Plant response to changes in disturbance magnitude
… 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 …

Plant community assembly and biodiversity: a spatio-temporal perspective
… phylogenetic, functional) were characterized in semi-natural grasslands (in plots of 0.5 × 0.5 and 2 × 2 m, and whole grassland polygons). The extent to which the present-day and historical characteristics of the sites and their surrounding landscape explain the current diversity patterns was …

Seeing the light: germination, growth and flowering responses in wildflowers under artificial nighttime lighting
… altering the timing, intensity and spectra of natural light regimes worldwide. Artificial light at night (ALAN) is predicted to constitute a significant anthropogenic pressure on natural biological systems, which are organized foremost by light, and particularly by daily and seasonal cycles of …
