6. Aerosol deposition to coastal forests: a wind tunnel approach
Abstract : Aerodynamically rough surfaces of forests provide for efficient air/ canopy exchange of mass, heat and momentum. In that context, the effects of forest edges come into focus, and therefore, coastal-zone forests constitute aparticular concern. READ MORE

7. Circumpolar impacts of herbivores on Arctic tundra vegetation
Abstract : Arctic tundra vegetation provides many ecological services that have implications for the global climate. However, the tundra biome is currently changing in response to increasing temperatures. Herbivores may mitigate some of these responses to warming through their impact on Arctic vegetation. READ MORE

8. Interception and storage of wet deposited radionuclides in crops : field experiments and modelling
Abstract : The emission of radionuclides into the atmosphere from various sources, such as nuclear power plant accidents and nuclear bomb explosions, can result in the interception and uptake of radionuclides by crops in the agricultural ecosystem. These radionuclides e.g. READ MORE

9. The Role of Vegetation-Climate Feedbacks in Regional Earth System Dynamics
Abstract : The hypothesis of this thesis is that climate models should take structural vegetation changes that operate on interannual to centennial time scales into account in order to simulate climate change in a more realistic manner. To evaluate this hypothesis, a regional Earth System Model (ESM) has been developed, validated and applied over Europe. READ MORE

10. Thermal energy use in greenhouses : the influence of climatic conditions and dehumidification
Abstract : In the North European greenhouses, energy use for climatization accounts for a significant share of the operational costs. Air temperature and humidity are important factors whose control is crucial for assuring high productivity and limited use of energy. READ MORE
