11. Sexual Conflict and Gene Expression in Drosophila melanogaster
Sammanfattning : Sexual conflict is broadly defined as a conflict between the evolutionary interests of the two sexes. Depending on the genetic architecture of the traits involved, it can occur at the level of male-female interactions or take the form of selection acting to change the mean of a shared trait against the sign of its genetic correlation.

12. Secondary succession in tropical dry forests : drivers and mechanisms of forest regeneration
Sammanfattning : Secondary succession is a complex process involving numerous factors acting across scales. Understanding secondary succession in tropical dry forests is important for the conservation and restoration of this highly threatened biome. LÄS MER
13. Outbreak dynamics of the spruce bark beetle Ips typographus in time and space
Sammanfattning : The European spruce bark beetle Ips typographus (L.) is one of the most important pests of mature Norway spruce Picea abies (Karst.) in Europe. Outbreaks (periods with large-scale beetle-caused tree mortality) are often triggered by large-scale stormfellings or drought, which provide a large surplus of suitable breeding material. LÄS MER
14. Regulation of litter decomposition in forest ecosystems of Sweden and New Zealand
Sammanfattning : Litter decomposition is a core ecosystem process critical for carbon and nutrient cycling, and the functioning of terrestrial ecosystems. This thesis explores two contrasting ways by which plants can influence litter decomposition in forested ecosystems. LÄS MER
15. Structuring factors for macroinvertebrate communities and the importance for ecosystem processing
Sammanfattning : Aquatic macroinvertebrates play important roles in our ecosystems and are essential for the ecosystem processing. An improved knowledge of structuring factors, such as competition and predation, and the way in which they operates in the macroinvertebrate community is crucial for our understanding of not only the macroinvertebrates but also the ecosystem in general.
