Ecology and evolution of plant populations

Our research group studies the population biology of plants. We are particularly interested in plant adaptation along climatic gradients and the ecological and evolutionary consequences of plant-pollinator and plant-herbivore interactions. We use a combination of field and greenhouse experiments, demographic and genetic studies to analyze factors governing the structure and dynamics of plant populations, population differentiation, and the evolution of morphological and phenological characters in plants.

Some ongoing projects:

Ecology and evolution of adaptive population differentiation in Arabidopsis lyrata and A. thaliana
Land use, biotic interactions and population differentiation in Primula farinosa
Local adaptation and life-history variation in Arabis alpina
Biotic interactions and population structure in tristylous Lythrum salicaria
Reproductive biology and population dynamics of orchids
