1. Arthropods in Constructed Wetlands : Ecosystem Processes and Riparian Biodiversity
Abstract : Constructed wetlands in the agricultural landscape are known to harbor immense arthropod biodiversity, however, riparian arthropod communities have often been neglected compared to aquatic communities when studying environmental responses. These wetlands are highly productive, but vary in form and composition based on its purpose, which influences the communities that inhabit them. READ MORE

2. Natural enemies: Functional aspects of local management in agricultural landscapes
Abstract : Agricultural intensification has raised the global food production but also caused major concerns about environmental and health effects, including contamination by pesticides. Pesticide applications may induce toxicity not only on the target pest species but especially on non-target species. READ MORE

3. Baltic shore-lands facing climate change
Abstract : This thesis provides new insight concerning drivers behind differences in arthropod diversity and abundance in Baltic shore ecosystems and how the arthropod communities might be affected when the conditions in the Baltic Sea are altered due to climate change. The focus has been on climate related changes that are unique for coastal ecosystems, especially sea level rise and changes in the inflow of marine nutrients. READ MORE

4. Attract, reward and disrupt: combining habitat manipulation and semiochemicals to enhance pest control in apple orchards
Abstract : Agricultural intensification entails negative effects on natural enemy populations and the pest regulation services they provide. Habitat manipulation holds potential to control pests with less negative effects on the environment than conventional methods. READ MORE

5. Phylogeny, taxonomy and species delimitation of water mites and velvet mites
Abstract : This study is part of the Swedish Taxonomy Initiative (STI) - one of the most ambitious all taxa biodiversity inventories in the world. One of the pillars in STI is to support taxonomic research on the most neglected taxonomic groups with the aim to lift the level of knowledge of biodiversity in the country. READ MORE
