Organisation Profile
We investigate the winter ecology and overwintering strategies of plants. Much of the work is focused on the seasonality of plants in a warming winter climate, with special emphasis on the role of snow in northern ecosystems. We have applied a range of methods, such as overwintering experiments under diverse climatic conditions in the field (reciprocal overwintering experiments), snow manipulations, growth chamber experiments, and ecophysiological modelling.
Our recent topics include:
- photosynthetic activity of plants outside growing season and under snow
- effects of microclimate on arctic-alpine plants
- effects of winter climate on annual plants
- invasive species in a warming winter climate
- winter dormancy and phenology of plants in a warming climate
- interactions between canopy, snow and vegetation
