11. Two strategies for dealing with uncertainty in social-ecological systems
Sammanfattning : The scale of environmental problems is increasing. Globalisation and trade haveweakened the links between the ecosystems in which goods are produced and thecommunities in which they are consumed. LÄS MER
12. How to estimate environmental persistence : Understanding persistence of organic micropollutants in rivers from a multidisciplinary perspective
Sammanfattning : Organic micropollutants such as food additives, pharmaceuticals and personal care products are found in rivers worldwide. Persistence is a key criteria in chemical risk assessment as micropollutants that are persistent pose an exposure hazard to humans and the environment. LÄS MER
13. Water Quality in Swedish Lakes and Watercourses : Modeling the Intra-Annual Variability
Sammanfattning : Water quality is of great importance for ecosystems and society. This thesis characterized and modeled the variation in several key constituents of Swedish surface waters, with particular consideration given to intra-annual variability and sensitivity to climate change. LÄS MER
14. Environmental Modeling and Uncertainty
Sammanfattning : Environmental fate models are used to evaluate the fate and effects of chemicals for risk assessment. Fate models may be effective and low-cost substitutes for field measurements and are helpful to project future scenarios. LÄS MER
15. Bacterioplankton in the light of seasonality and environmental drivers
Sammanfattning : Bacterioplankton are keystone organisms in marine ecosystems. They are important for element cycles, by transforming dissolved organic carbon and other nutrients. Bacterioplankton community composition and productivity rates change in surface waters over spatial and temporal scales. LÄS MER
