16. Effects of forest fire and the ecology of fire-adapted insects
Abstract : Fire is widely recognised for its major impact on boreal forest ecosystems. The altereddisturbance regime due to effective fire suppression and extensive forestry may be a majorthreat to biodiversity.If logging preceded burning, the pyrophilous (Gr. fire-loving) beetle Sericoda quadripunctata failed to reproduce.

17. Botanical Repellents and Pesticides Traditionally Used Against Haematophagous Invertebrates in Lao PDR
Abstract : Haematophagous parasites and disease vectors such as leeches, ticks, mites, lice, bed bugs, mosquitoes, and myiasis-causing fly larvae are common health problems in Lao Peoples Democratic Republic (Lao PDR). A main aim of my field work in Lao PDR in 2006-2010 was to document traditional knowledge among different ethnic groups about plants that people use to repel or to kill blood-feeding invertebrates.

18. Context dependency of plant – animal interactions
Abstract : The strength and direction of interactions between organisms vary spatially across the landscape. Traditionally, the focus has been on how trait variation affects the interactions between species. However, differences in abiotic and biotic environmental factors may also alter the distribution, phenology and behavior of the interacting species. READ MORE

19. Aspects of Optical Broad Band Spectroscopy and Information Extraction - Applications in Medicine and Ecology
Abstract : The present thesis describes a number of aspects of modern electro-optical measurement technology also known as bio-photonics; this includes instrumentation, applications, sample interaction and data interpretation. The methods employed operate over several domains, and light measurements are discretized both in intensity, space, angle, time, polarization and energy. READ MORE

20. Charting Insect Diversity
Abstract : Background: Despite Sweden's rich legacy in entomology, a significant portion of its insect fauna remains poorly studied. Addressing this and other biodiversity knowledge gaps, the Swedish government unveiled the Swedish Taxonomy Initiative (STI) in 2002, with the ambitious goal of documenting and scientifically describing all multicellular species in the country.
