Our study emphasizes the importance of preserving ecosystem structure and functioning. We showed that a large decrease of the cod population has cascaded down the food web influencing the whole Baltic Sea ecosystem, from planktivorous fish to primary producers.
These findings highlight the fact that, in order to dampen the summer blooms of phytoplankton, often characterized by potentially toxic species, effort should be addressed to prevent large changes at the higher trophic levels, and not only to control anthropogenic nutrient inputs.
This is particularly urgent in low-diversity ecosystems, as the Baltic Sea, where there is lower species compensation.
