1. Wastewater treatment in constructed wetlands : Effects of vegetation, hydraulics and data analysis methods
Sammanfattning : Degradation of water resources has become one of the most pressing global concerns currently facing mankind. Constructed Wetlands (CWs) represent a concept to combat deterioration of water resources by acting as buffers between wastewater and receiving water bodies. LÄS MER
2. Effects of carbon dioxide and ozone on wheat crop yield and grain quality
Sammanfattning : Atmospheric concentrations of carbon dioxide (CO2) and ozone (O3) have steadily increased since the industrial revolution. CO2 and O3 directly affect plant physiology, CO2 being an essential substrate for photosynthesis, while O3 is an oxidative agent causing damage to plant tissues. LÄS MER
3. Nutrient Recovery as an Added Benefit to Harvests of Photosynthetic Marine Biomass : A Holistic Systems Perspective on Harvesting Marine Microalgae, Cyanobacteria, and Macroalgae
Sammanfattning : As a result of increasing environmental burdens from anthropogenic activities andresource scarcity, interest for the development of solutions utilizing photosyntheticmarine biomass has also been increasing in both academia and industries. Medium tolarge scale production and harvest of photosynthetic marine biomass have beenpracticed to achieve numerous services, including improving tourism industries,production of biofuels, and production of food/feed.

4. Inference and management of populations in variable environments
Sammanfattning : Population dynamics in space and time are manifested as changes in the distribution and abundance of organisms. To couple such patterns to the underlying processes is a central question in ecology and also key to successful management. LÄS MER
5. Potential impact of climate change on European agriculture: a case study of potato and Colorado potato beetle
Sammanfattning : European agriculture is facing the challenge of managing the impact of climate change on food security. Agriculture in a northern temperate climate is likely to benefit from higher temperature and longer growing season while, in the south, crop productivity is likely to decline. LÄS MER
