Aquatic ecosystems contribute to human wellbeing by providing food, clean water, economic and recreational benefits. Anthropogenic and environmental changes impact the functioning and output of these ecosystems, often via inducing changes in traits of key species. Overfishing, temperature or acidity changes and landscape transformations are only some of the possible drivers at play. Changes in species’ traits, whether plastic or evolutionary, influence their interactions and population dynamics and thus propagate across trophic levels and scales. Such ecosystem-wide effects, but also the immediate effects on exploitability and usability indicate the far-reaching consequences of trait changes in aquatic ecosystems. Owing to this complexity of ecological, societal and economic feedback, transdisciplinary approaches are necessary to fully understand these dynamics. Tackling problems such as overfishing and biodiversity decline while incorporating stakeholders’ interests requires a translational approach of applying results from basic research to concrete problems and specific case studies. This symposium discusses how modelling can account for these diverse aspects and sheds light on the translational significance of trait changes in aquatic ecosystems.
