Marine Food Webs

Food webs form the backbone of functioning in ecosystems. We study how food web structure and functioning vary over time and space, how the changing marine environment influences the biodiversity of the food web as well as the interactions among the taxa and what the consequences are for energy fluxes through the communities. In addition to using network approaches, we explore changing marine communities using trait-based approaches and stable isotope ecology. We rely on long-term monitoring data as well as targeted field sampling and experimental approaches in our investigations of trophic interactions among marine organisms, and our work covers both coastal ecosystems and deeper areas in the Baltic Sea, the North Sea, and the Arctic Ocean.
