Globally unprecedented disruptions (e.g. biodiversity loss, nutrient and pollutant inputs, climate crises etc.) are taking place in freshwater ecosystems with major consequences of losing biodiversity and ecosystem services. Obtaining quantitative mechanistic understanding of aquatic ecosystem structure and functioning is ever more curial for taking sound measures of adaptation and mitigation. Well controlled and highly replicated empirical approaches from small-scale laboratory microcosm experiments have been used to relate changes in plankton food webscommunities to altered environments, however, their realism is limited and the extrapolation to natural systems is often difficultseen problematic. Large-scale mMesocosm (or enclosure) experiments allow a more realistic setting by including a higher complexity in terms of trophic levelsnatural food web including multiple trophic levels, and thus potential with its potential interactions. Thus, mesocosms experiments is provide a powerful approach tool to obtain quantitative and such mechanistic quantitative understanding of ecosystem responses to anthropogenic pressures. To this session we therefore welcome researchers to present their ecosystem-scale empirical work where scientific questions about various aspects of aquatic ecosystem functioning has been tested through using mesocosms.
Abstract submission will start in January and close in February 2020.
