Research Project
In the project I am working on, we are testing the relative roles of competition and plant soil feedbacks in explaining commonness and rarity of native and alien plant species.
We want to know in how far differences in intraspecific competition and frequency-dependent plant soil feedback may explain differences in species abundance. Therefore we are conducting experiments that focus on three aspects of plant life history (individual plant growth/ plant population growth/ establishment success)
We test whether individual plant growth of the common species is less affected by high intraspecific plant frequency and when grown on soils previously occupied by themselves (at increasing frequencies), than performance of the rare species.
Secondly, we want to know whether fungal pathogens and intraspecific competition affect population growth rates of annual plant species communities of rare and common natives and aliens.
Furthermore we are testing whether establishment success of common natives and aliens in the field is linked to competitive ability, lower impact of soil pathogens or a combination of both.
