The Institute for Biodiversity and Ecosystem Dynamics (IBED) is one of eight research institutes of the Faculty of Science at the University of Amsterdam. Research at IBED targets the world around us from the level of molecules and genes to entire ecosystems. We aim to unravel how ecosystems function in all their complexity, and how they change due to natural processes and human activities. At the core of IBED lies the integrated approach to study biodiversity, ecosystems and the environment using methods typical of the disciplines of ecology, physical geography and environmental chemistry. Research themes: Ecosystems and Landscape dynamics, Evolutionary and Population Biology, Freshwater and Marine Ecology & Theoretical and Computational Ecology
