Ecosystem flow dynamics in the Baltic Proper-Using a multi-trophic dataset as a basis for food-web modelling

► The model simulates the dynamics and flows of the food-web in the Baltic Proper. ► The model explains 51% of the variation in biomass of multiple trophic levels. ► Model is able to simulate the system reorganisation in the late 1980s. ► Macrozoobenthos is transferring energy directly from lower to high trophic levels. ► Fisheries affected the food-web equally as the environmental factors.
