The Quantitative Macroecology group aims to understand how natural ecosystems are assembled and maintained. We specifically focus on the mechanisms behind macroecological patterns, such as the maintenance of species diversity, spatio-temporal variation in species composition, and the latitudinal gradient of species diversity. We integrate diverse approaches, including data collection in the field and through experiments, statistical data analyses, mathematical modeling, and literature synthesis, to achieve mechanistic and quantitative understandings of ecological processes in complex ecosystems.
