Mission Statement

My research focuses on ecological and evolutionary processes in plant populations. I am particularly interested in patterns of selection and genetic connectivity within and across landscapes. My research contains three core areas: adaptation and phenotypic plasticity, the genomic basis of adaptation and genetic connectivity from population to landscape scale. With my research I aim to contribute to the knowledge building to mitigate effects of environmental change on plants and ecosystems based on traditional but also newly available genomic research methods. Sustainable plant populations are of particular importance because they contribute substantially to ecosystem resilience and resistance.


PhD projects supervision

Integrating genetic diversity and phenotypic plasticity into plant population responses to climate change in the Alps (BioChange CCES) - 2008 to 2013

Within the group of Ecosystem Management I led the BioChange project on plant reactions to climate change in alpine habitats, particularly with respect to the supervision of three PhD students, scientific reporting and administrative and financial matters. Congratulations to the three PhD candidates who earned their degree in early March 2013!
Following topics were tackled by:

Esther Frei: Adaptation and plasticity of plant populations in the Swiss Alps in the context of climate change.
Thomas Hahn: Low impact of altitude and landscape composition on patterns of genetic variation in semi-dry grassland plants.
Philippe Matter: Estimating contemporary pollen-flow and associated outbreeding effects on herbaceous plant populations along altitudinal gradients.

Dr. Chris Kettle contributes to the supervision of the molecular project parts.

Allee effects and plant conservation: Trollius europaeus-Cheistocheta spp. interaction in a fragmented landscape - 2006 to 2011

In collaboration with Prof. Dr. Jaboury Ghazoul, I supervised Charlotte Klank, who studied the pollination system, plant performance and genetic diversity in differently sized populations of T. europaeus. My focal support laid in the quantitative genetics and molecular experiments including statistical analyses and writing.

Maintenance of diversity in tropical rain forests: The paradox of soil-specialists and soil-generalists Dipterocarp species - 2006 to 2011

In collaboration with Prof. Dr. Jaboury Ghazoul, I supervised Julia Born who studied mechanisms of co-existence in the Shorea genus. My focal contribution were discussions of experimental procedures during the field work and statistical support for the analyses of plant growth.


Adaptive variation in European beech across a multitude of environmental conditions in Switzerland - ongoing

European beech, the most dominant and economically important broadleaved forest tree of Switzerland, occurs across a wide variety of environmental conditions and is thereby expected to be under divergent selection. Understanding the genomic basis of adaptation has a high application potential. I investigate the variation of over 150 SNPs in genes of known functions in 79 provenances of Switzerland. An environmental association analyses will indicate the adaptive divergence and eventually indicates which provenances might serve best as seed sources for our future forests under climate change. In this project I collaborate with A. Frank, Drs. P. Brang, C. Sperisen and C. Heiri (WSL), Drs. S. Oddou-Muratorio and H. Lalagüe (INRA, Avignon) and Dr. G.G. Vendramin (CNR, Florence). This genomic project complements a large-scale common garden experiment at WSL called ADAPT.

Does seed size differ between lowland and alpine plant species? - ongoing

Based on seed weight data of c. 1300 lowland and alpine plant species from Switzerland, we test the hypothesis that selection favours larger seeds in the harsher environmental conditions at higher altitudes. Thereby we will also consider phylogenetic contrasts and the influence of habitat preference as well as plant traits. This project is a collaboration with Prof. Dr. J. Stöcklin (University of Basel) and Dr. W. Schütz (Germany).

Evaluation of European beech genetic resources at dry and mesic sites in Switzerland - 2009 to 2011

In this project, we found indications that European beech at nearby dry and mesic sites is adapted to soil moisture availability based on an AFLP outlier analysis. We also studied the dendrochronological characteristics of the trees and combined this dataset with the genetic dataset. This study was a collaborative work with Dr. Pascale Weber.
