1. Searching for food in complex environments : Integrating processes at multiple spatial scales
Sammanfattning : Resources are often unevenly distributed through the environment, resulting in a challenging task for insects to locate food, mates and oviposition sites. Consequently, there is an ongoing need to unravel how insects rely on behavioural and sensory traits while searching for resources in heterogeneous environments. LÄS MER
2. Towards Pharmacological Treatment of Cystic Fibrosis
Sammanfattning : S-nitrosogluthatione is an endogenous substance, present at decreased levels in the lungs of CF patients and was recently found to induce mature CFTR in airway epithelial CF cell lines. We show that S-nitrosoglutathione in physiological concentrations increases the presence of ΔF508 CFTR in the cell membrane and induces cAMP dependent chloride transport in cystic fibrosis airway epithelial cells.

3. 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
4. Food selection and fitness optimisation in insects
Sammanfattning : To optimise fitness is a continuous process which assists species survival in changing environments. Choosing an optimal diet is an essential part of the optimisation process and a key element of optimal foraging theory. LÄS MER
5. Systematics of Eucoilini : Exploring the diversity of a poorly known group of Cynipoid parasitic wasps
Sammanfattning : Many animal species are still undiscovered, even in Sweden. This thesis deals with the wasps of the subfamily Eucoilinae (of Figitidae, Cynipoidea), a poorly known group of small parasitoids of Dipteran flies. LÄS MER
