1. Diurnal variation of stratospheric short-lived species
Sammanfattning : 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.

2. Local adaptation in life history traits and population size estimation of aquatic organisms
Sammanfattning : Human society is dependent on healthy aquatic ecosystems for our basic needs and well-being. Therefore, knowledge about how organisms respond and interact with their environments is pivotal. LÄS MER
3. The importance of wetlands for biodiversity in agricultural and urban landscapes
Sammanfattning : The aim in this thesis was to study the importance of different types of wetlands for the biodiversity in a landscape. The landscapes were both agricultural and urban, and wetlands were in different successional stages. Diving beetles (Dytiscidae) were used as study organisms. LÄS MER
4. Life-history traits and population differentiation in a clonal plant: implications for establishment, persistence and weediness
Sammanfattning : Clonality is wide-spread among plants, and clonal plants dominate many habitats and include many highly invasive species. Clonal growth incurs both advantages and costs and clonal plants often have reduced sexual reproduction compared to non-clonal plants which could be expected to lower genetic variation and hence evolutionary potential.

5. Extracting Genomic Variations using Selector Technology
Sammanfattning : This thesis describes the development and use of a new class of molecular tools called Selector probes, and its potential for investigations of genetic variation. The Selector technology provides multiplex amplification of targeted DNA sequences with a high specificity, and an enrichment factor in the same order of magnitude as PCR. LÄS MER
