"Three different experimental approaches will be applied in order to analyze plant features which can contribute to a high competitive ability under different nutrient availability and can lead to successful expansion of tall grasses into dry grassland communities. Therefore the adaptation of several grass species to habitats with different nutrient availabilities (including increased atmospheric deposition of nitrogen) will be studied The consequences of nitrogen losses due to simulated mowing will beexamined under conditions o1 high and low soil fertility. The objective of the proposed project will be also the study of root proliferation and root foraging ability, and their consequences for the nutrient acquisition of several grass species in order to examine weather a higher ability to forage for patchily distributed resources confer a competitive advantage in heterogeneous environments. The effects of the nutrient treatment will be examined in the fink to learn weather enhanced nitrogen"@en . . . . . . . .
