Testing the potential of priority effects to sustainably increase community function in semi-natural grasslands
… priority effects to influence central European semi-natural grasslands in terms of functionality (biomass production), species composition and the interplay of both. This has implications for the general understanding of (plant-) community assembly, restoration practise, and land management as …

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 …

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 communities along Irish roads: the impact of humans and potential to improve biodiversity
… was significantly lower than that found in semi-natural grasslands. Road verges held greater resources for pollinators than the agricultural landscape, including field margins in many circumstances. Road verges contained the highest incidence of non-native species: few were recorded outside …

Population of Gladioulus imbricatus under diverse management regimes in SW Estonia
… endangered species within plant communities of semi-natural grasslands. Coastal meadows, extensively managed as pastures or meadows, are amongst its favored habitats and thrive with biodiversity in fauna and flora. However, following major land-use changes during the last century, proactive …

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 …
