PhD, Post-doctoral researcher
I am interested in interactions of plants with their environment, especially in high latitude and altitude environments, applying novel approaches to retain and facilitate ecosystem services of managed and unmanaged ecosystems. I seek to understand those interactions on multiple ecological scales (communities, individuals and genetics) to obtain an overview from multiple perspectives of plant communities and individuals.
In the current project, I am evaluating consequences of landscape and habitat changes on the genetic diversity and potential adaptive response of plants in calcareous grasslands. The main tool for this landscape genetic approach is a state-of-the-art molecular technique in combination with environment and landscape analysis to determine connectivity-related gene flow and distribution of genetic diversity in fragmented plant populations. In addition, we are interested in the potential adaptation of grassland plants to various environmental variables. The project enables us to obtain fundamental insights into the landscape-driven genetic distribution and background of plants, which can serve as a basis for guiding decision-making in environmental conservation policy.
