The pressure on marine ecosystems and the services they deliver is increasing dramatically due to global change combined with anthropogenic activities. METRIC addresses the impact of these stressors on the relationship between marine functional diversity and ecosystem stability using existing ecosystem-wide databases on marine biodiversity, ecosystem functioning and environmental settings. Research will target biogeochemical cycling (proxy for ecosystem functioning) and food-web topology (clues to ecosystem stability), integrating data from the pelagic and benthic realm. These results will contribute to the emerging research field on the link between biodiversity and marine ecosystem services. As such, this project will directly link fundamental scientific research with societally relevant outcomes.
