I am a plant ecologist with a great passion for experimental biology. My previous research focused on invasion biology, plant stress (UVB and drought) and plant-soil feedback. I joined iDiv because it is a great opportunity for me to learn different approaches in ecology and to expand my scientific and personal horizon.
My Research Project
Assembly of native and exotic grassland communities – the role of mutual invasibility, priority effects and time
My research project aims to understand under which circumstances priority effects of earlier arriving plant species are more important than mutual invasibility (i.e. the “rare species advantage”) and vice versa. I expect coexistence and therefore mutual invasibility should to be of higher importance among native species, in particular among different functional groups, while interspecific priority effects should be more important between invasive exotic species and native species, and within the same plant functional group of either native or exotic species.
To test my hypotheses I will conduct field and greenhouse experiment with native and exotic plant species of different functional groups (grasses, herbs and legumes). Furthermore I will include a fungicide treatment that allows me investigate to role of soil fungi and therefore plant-soil feedbacks.
