21. The spatial and temporal dynamics of plant-animal interactions in the forest herb Actaea spicata
Sammanfattning : Landscape effects on species performance currently receives much attention. Habitat loss and fragmentation are considered major threats to species diversity. Deciduous forests in southern Sweden are previous wooded pastures that have become species-rich communities appearing as islands in agricultural landscapes, varying in species composition. LÄS MER
22. Multiple forces drive the Baltic Sea food web dynamics and its response to environmental change
Sammanfattning : Understanding the interaction of multiple drivers and their compounded effects on ecosystem dynamics is a key challenge for marine resource management. The Baltic Sea is one of the world’s seas most strongly impacted by effects from both human activities and climate. LÄS MER
23. New Perspectives in Multi-trophic Aquaculture
Sammanfattning : Aquaculture, the farming of marine and aquatic organisms, is currently the fastest growing food production sector globally. As capture fisheries have stagnated and the fishing down of marine food webs has been seen to be unsustainable, aquaculture is filling the deficit in providing food to a growing world population.

24. Light, stress and herbivory : from photoprotection to trophic interactions using Arabidopsis thaliana as a model organism
Sammanfattning : Photosynthesis is the most important process for nearly all life on earth. Photosynthetic organisms capture and transfer light energy from the sun into chemical energy which in turn provides a resource base for heterotrophic organisms. Natural light regimes are irregular and vary over magnitudes. LÄS MER
25. Piscivore-prey fish interactions - consequences of changing optical environment
Sammanfattning : Predator-prey interactions are a primary structuring force in aquatic systems. A change in the predator-prey interactions may cause a change in the strength of trophic cascades and even resulting in ecosystem shifts. LÄS MER
