Quantifying energy flows and food web interactions
Baltic marine ecosystems have gone through substantial structural changes during recent decades.
The aim of an ecosystem model for the Baltic Proper (BaltProWeb) is to quantify the flows, simulate food–web interactions and explore the effects of external multiple drivers (i.e fisheries, eutrophication and climate).
In particular, the model addresses the
- temporal changes in energy flows
- trophic controls between certain functional groups of the food–web; and
- role of fisheries using ecosystem resources.
This will lead towards a more comprehensive tool for ecosystem-based management of the Baltic Proper.
Detail formulations of BaltProWeb and model-data comparisons are presented here and here.
The only end-to-end model of the Baltic Sea ecosystem
BaltProWeb has been used as a one of the major scientific tools in many large interdisciplinary research projects, including the BONUS-financed ECOSUPPORT project and the EU-financed KNOWSEAS project.
Recent BaltProWeb implementations include simulation of the long-term development of the Baltic Sea food-web 1974-2006, historical hindcast of Baltic Sea ecosystem 1925-1974 (in prep), simulations scenarios for future states, as well as its participation in the ensemble modelling of the cod stock.
Furthermore, BaltProWeb has also been used as a simulation tool for economic analysis (as well as for fishery management strategy evaluation with ecosystem considerations).
