1. Chemical signals in interactions between Hylobius abietis and associated bacteria
Sammanfattning : The pine weevil (Hylobius abietis L.) is one of the two topmost economically important insect pests in Swedish conifer forests. The damage increase in areas were the silvicultural practice is to use clear cuttings were the insects gather and breed. LÄS MER
2. Importance of tannins for responses of aspen to anthropogenic nitrogen enrichment
Sammanfattning : Boreal forests are often strongly nitrogen (N) limited. However, human activities are leading to increased N inputs into these ecosystems, through atmospheric N deposition and forest fertilization. LÄS MER
3. Phenolics, Nitrogen, and Biotic Interactions : A Study of Phenylpropanoid Metabolites and Gene Expression in the Leaves of Populus tremula
Sammanfattning : European aspen (Populus tremula) is a fast growing tree species, rich in phenolic compounds. Defense theories suggest that soil nitrogen greatly influence plant allocation togrowth and defense; however, the allocation priorities are not well understood. LÄS MER
4. Candidate genes for resistance and susceptibility to the bird cherry-oat aphid (Rhopalosiphum padi L.) in barley (Hordeum vulgare L.)
Sammanfattning : Bird cherry-oat aphid (Rhopalosiphum padi L.) is an important pest on spring-sown cereals. The aphid reduces yield and can act as a vector of barley yellow dwarf virus. R. LÄS MER
5. Black mustard and the butterfly effect : metabolomics of plant-insect interactions under multiple stress conditions
Sammanfattning : One main goal of ecological research is to understand nature´s complexity, in order to predict the potential impact of environmental perturbations. In this thesis, I investigate the ecological interactions between some of the most ancient organisms living on our planet: plants and insects. LÄS MER
