Marco Moretti is a community ecologist working at the Swiss Federal Research Institute WSL in Birmensdorf-Zurich, Switzerland. His research focuses on trait mediated relationships between multi-trophic biodiversity, interaction networks and ecosystem functioning. He addresses on fundamental and applied research questions and combines manipulative and field experiments by investigating causes and consequences of biodiversity changes in both natural and human dominated ecosystems. In urban ecology, Marco Moretti leads trans- and interdisciplinary projects on the ecological and social values of urban nature by collaborating with ecologists, social scientists and psychologists. In particular, he investigates direct and indirect effects of social and ecological drivers on ecosystem processes and services, and tests if and how these are mediated by changes in biodiversity and trophic interactions. Marco Moretti is a member of the Swiss Biodiversity Forum and of UrBioNet, the Urban Biodiversity Research Coordination Network.
