11. Long Term Studies of Insect Abundances in Temporary Wetlands in Relation to Hydrology, Predation and Bti
Abstract : Long-term insect abundances have been studied to investigate factors structuring the insect communities of the temporary wetlands around the River Dalälven floodplain. In the wet meadows and swamps in the River Dalälven floodplains recurrent floods are the ultimate prerequisite for high production of floodwater mosquitoes. READ MORE

12. Get a grip on chaos : Tailored measures for complex systems on surfaces
Abstract : Complex systems are ubiquitous in physics, biology and mathematics. This thesis is concerned with describing and understanding complex systems. Some new concepts about how large systems can be viewed in a lower dimensional framework are proposed. The systems presented are examples from ecology and chemistry. READ MORE

13. Mosquitoes as a Part of Wetland Biodiversity
Abstract : Wetlands contain both aquatic and terrestrial environments which generates high biodiversity. However, they are commonly associated with mosquitoes (Diptera: Culicidae), and mosquitoes are usually regarded as negative by humans because they can cause nuisance and transmit diseases. READ MORE

14. Olfactory genomics of bark- and ambrosia beetles : Evolution and function of chemoreceptors
Abstract : Insect behaviours, such as host and mate selection, are often mediated by chemical cues. The chemical cuesare detected by large and rapidly evolving families of chemoreceptors which include odorant receptors (ORs),gustatory receptors (GRs) and ionotropic receptors (IRs). READ MORE

15. Population biology and conservation of beetles and pseudoscorpions associated with hollow oaks
Abstract : Many species associated with old trees are threatened, as this habitat has decreased severely in Europe during the last 200 years. In old oaks, hollows with wood mould often form in the trunks and these harbour a specialized fauna mainly consisting of beetles, flies and pseudoscorpions. READ MORE
