Sažetak
Jellyfish are conspicuous components of marine ecosystems and recognized as valuable indicators of ecosystem performance and change. Although changes in their population size have been described for long time, recent reports indicate an increase of jellyfish proliferations in different shelf seas worldwide. In this study we used a comparative approach based on time series data and ecosystem modeling to evaluate how food web complexity and ecosystem degradation interact with the dynamics of jellyfish. The ecosystems investigated represent two contrasting environments, the Kiel Fjord, south-western Baltic Sea, and the Marine Protected area of the National Park Mljet, in the south Adriatic Sea. The results show that jellyfish dynamics is favored by food web degradation, which together with global warming, allow higher variability in jellyfish outbreaks. The consequences of such dynamics may jeopardize the ecosystem resilience under global warming scenarios.
