Plant Population and Evolutionary Biology

Adaptation and phenotypic plasticity are both crucial for the long-term survival of plants in changing world. Our actual research is focused on the functional consequences of the highly structured alpine landscape for demographic, reproductive and evolutionary processes in plants. With increasing altitude, plant life is challenged by low temperature, more snow, a shorter vegetation period, and harsher conditions due to a rising number of extreme weather events. 

We aim to explain the pattern of within and among species diversity in relation to altitude, biogeographic factors and human land use, We ask how far the the glacial history of the Alpine flora has affected genetic diversity and ecologically relevant differentiation and adaptation of species. We try to quantify the importance of genetic processes and phenotypic plasticity for local adaptation in functionally important plant traits. 

We combine observational studies, molecular analysis, field-, greenhouse and common garden experiments as well as demographic modelling to answer questions and test hypotheses.
