2. Diurnal variation of stratospheric short-lived species
University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm UniversityAbstract : Diurnal variation of stratospheric short-lived speciesMaryam KhosraviChalmers University of TechnologyDepartment of Earth and Space SciencesAbstractThe depletion of ozone in the stratosphere has a direct impact on the amount of ultravioletradiation reaching the Earth’s surface. The ozone abundance and distributionis controlled by the photo-chemical reactions and catalytic cycles involving halogens(chlorine and bromine), odd hydrogen and odd nitrogen species as well as by atmospherictransport.

3. Bacterioplankton in the light of seasonality and environmental drivers
University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm UniversityAbstract : 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. READ MORE

5. The Nitrogen Cycle in Soil - Climate Impact and Methodological Challenges in Natural Ecosystems
University dissertation from Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm UniversityAbstract : Nitrogen (N) is a fundamental element for life, and limiting in many terrestrial ecosystems. In non-N-fertilized ecosystems, the N inputs can be low, and the nutrient availability for plants is determined by the internal cycling of N. READ MORE
