Research interests

I am interested in the population dynamics of forest ecosystems and the adaptive potential of trees in the face of changing environmental conditions.

In my PhD-project I am combining dendroecological methods with common garden and reciprocal transplantation experiments to study the phenotypic plasticity and local adaptation of Fagus sylvatica L. (European Beech).

For the core of my research project – the fully reciprocal transplantation experiment – we set up 12 experimental sites inside and outside of the natural distribution range of F. sylvatica, reaching from the dry (Spain, France) to the cold limits (Poland, Sweden) of the species and beyond. At each site we planted over 1000 beech nuts of all different origins to compare their specific reaction on various ambient conditions. Here, my aim is to assess the genetic adaptation and to quantify the phenotypic plasticity of the different F. sylvatica provenances.

Finally, the results could contribute to a better understanding of the spatial distribution and evolutionary adaptation of F. sylvatica. The obtained estimates will ultimately allow for improved projections of future range shifts.
