Sammanfattning : An influence at one trophic level can result in dynamic impacts also on other components of a food web. These dynamics are known as trophic cascades, and can be both top-down and bottom-up. After a near-collapse of the Baltic cod Gadus morhua stock in the 1980s, its main prey sprat Sprattus sprattus increased dramatically. LÄS MER
Sammanfattning : Sustainable management of natural resources requires an in-depth understanding of the interplay between social and ecological change. Linked social-ecological systems (SES) have been described as complex adaptive systems (CAS), which mean that they are irreducible, exhibit nonlinear dynamics, have interactions across scales and are uncertain and unpredictable.

3. Social-ecological dynamics in a highly regulated fisheries system - Sources of resilience and limits to command-and-control management
Sammanfattning : Sustainable governance of natural resources is challenged by the poor understanding of complex human-nature couplings. Major advancements in resilience theory, acknowledging the importance of social-ecological linkages and the self-organizing capacity of social-ecological systems, provides a new perspective on research in sustainability science.

Sammanfattning : Humans have become a dominant force of planetary change. This epoch, referred to as the Anthropocene, implies profound alterations to the Earth’s marine and terrestrial ecosystems upon which so many people depend. LÄS MER
Sammanfattning : Overfishing and climate change put increasing pressure on marine systems, with effects on commercially targeted fish and top predators dependent on these resources. To achieve sustainable resource use, governance mechanisms need to incorporate knowledge about ecosystem dynamics. LÄS MER
