1. Sea cages, seaweeds and seascapes : Causes and consequences of spatial links between aquaculture and ecosystems
Sammanfattning : Aquaculture is of growing importance in the global seafood production. The environmental impact of aquaculture will largely depend on the type of environment in which the aquaculture system is placed. LÄS MER
2. Radionuclides in the Baltic Sea : Ecosystem models and experiments on transport and fate
Sammanfattning : Manmade radionuclides have been introduced to the environment for almost a century. The main source has been the nuclear weapons testing programmes, but accidental releases from the nuclear power production industries have also contributed. The risk to humans from potential releases from nuclear facilities is evaluated in safety assessments. LÄS MER
3. Macroalgae in tropical seascapes : regulating factors and functions in the coastal ecosystem
Sammanfattning : Although macroalgae usually are inconspicuous on pristine coral reefs, they often thrive on reefs that are subjected to various types of anthropogenic disturbance. This thesis consists of five papers and investigates how biomass and composition of macroalgal communities on coral reefs are affected by regulating factors, such as nutrient availability, herbivory, substrate availability and hydrodynamic forces.

4. Human Abuses of Coral Reefs- Adaptive Responses and Regime Transitions
Sammanfattning : During the last few decades, coral reefs have become a disappearing feature of tropical marine environments, and those reefs that do remain are severely threatened. It is understood that humans have greately altered the environment under which these ecosystems previously have thrived and evoloved. LÄS MER
