6. Distribution patterns of macroinvertebrates in vegetated shallow soft-bottom bays of the Baltic Sea
Sammanfattning : .... LÄS MER
7. Effects of morphometric isolation and vegetation on the macroinvertebrate community in shallow Baltic Sea land-uplift bays
Sammanfattning : Shallow sheltered Baltic Sea bays are ecologically important habitats that harbour a unique vegetation community and constitute vital reproduction areas for many coastal fish species. Knowledge about the invertebrate community in these bays is, however, limited. LÄS MER
8. Nitrogen removal in treatment wetlands : Factors influencing spatial and temporal variations
Sammanfattning : Decreasing the nitrogen transport from land to surrounding seas is a major task throughout the world to limit eutrophication of the coastal areas. Several approaches are currently used, including the establishment of wetlands, to decrease the transport of nitrogen. LÄS MER
9. Interactions between Bacteria and Fungi on Aquatic Detritus – Causes and Consequences
Sammanfattning : Bacteria and fungi dominate the decomposition of aquatic plants, a major process in the carbon and nutrient cycling in many aquatic systems. Although phylogenetically distant, bacteria and fungi often live in close proximity with each other. Since these microorganisms also have similar ecological functions, interactions have developed between them. LÄS MER
10. Internal oxygen transport to below-ground parts: importance for emergent macrophytes
Sammanfattning : This thesis examines factors regulating growth and distribution of emergent plants with focus on effects of oxygen supply to the roots. Greenhouse experiments revealed that P. australis acclimatizes to specific water depths with phenotypic plasticity. LÄS MER
