Key Research Themes
Long-term nature observation series are indispensable records of how individual populations and species are responding to environmental change. In the Research Centre for Ecological Change we are systematically collecting long-term ecological data for an unprecedented syntheses of how communities of organisms are responding to change.
Biodiversity in a changing world
We are studying how natural communities are responding to global change and how interactions among species across trophic levels are changing as well.
Global plant demography
As part of PlantPopNet, we are driving a coordinated global effort combining data and theory to understand abiotic and biotic drivers of population persistence and distribution in a changing world.
Biological diversity and sustainable food production
Humans have intensified and mechanized agricultural processes in an effort to boost efficiency, productivity and profits. As a result, global food systems are increasingly generating severe social, environmental, economic and climate costs. We are investigating how mechanisms that promote stability in natural ecosystems could be utilized to develop sustainable and climate-smart food production systems.
Intraspecific variation in host-parasite interactions
Understanding how diversity is maintained in host and parasite populations is one of the core challenges in disease biology. Using long-term population dynamic data combined with genomics and experimentation, we address this question in a natural plant-pathogen interaction. This work brings us one step closer to answering questions of how risks of virulence and pathogen occurrence evolve – important questions from both basic and applied points of view.
Across biological systems it is becoming increasingly clear that host populations and even single host individuals are typically exploited by diverse pathogen communities. In our work we aim to understand the spatio-temporal determinants of this diversity, and what the eco-evolutionary implications are for both hosts and pathogens.
