We investigate two central questions in Ecology:
How can so many species coexist naturally? (Biodiversity maintenance)
What happens to natural ecosystems when species go extinct? (Biodiversity loss)
We live in a world of “eat or be eaten” where feeding interactions between organisms play an important role in structuring ecological communities. Therefore, we believe that multitrophic interactions are key if we are to fully understand mechanisms of natural biodiversity maintenance and consequences of biodiversity loss.
To find general answers to these questions, we work on a variety of multitrophic systems in a number of exciting places: from European grassland plant and insect communities to Costa Rican bromeliad food webs to tree-hole metacommunities in temperate forests and kettle holes in agricultural landscapes.
