1. Biodiversity & Biofuel. Harvest of Logging Residue Affects Arthropods
Sammanfattning : .... LÄS MER
2. Hygroscopic Properties of Aerosols from Open-Air Burning and Controlled Combustion of Biomass
Sammanfattning : The major uncertainty in predicting the influence of human activities on global climate change is the effect of aerosols. Two physical properties of aerosols largely controlling their influence on climate are the particle number size distribution and the interaction of the particles with the surrounding water vapor.

3. Vegetation and land-use in the Småland Uplands, southern Sweden, during the last 6000 years
Sammanfattning : Palaeoecological methods were applied to peat and sediment cores recovered from one bog (Bråtamossen) and two lakes (Avegöl and Femtingagölen) in the Småland Uplands, southern Sweden. The general aim was to reconstruct the landuse and vegetation history for the last 6000 years in this agriculturally marginal region. LÄS MER
4. Environmental Effects of Agricultural Expansion in the Upper Amazon : A study of river basin geochemistry and hydrochemistry, and farmers' perceptions
Sammanfattning : In this thesis natural science is combined with environmental psychology in order to determine how deforestation and subsequent agricultural expansion in the Peruvian highland jungle has affected the natural environment and rural livelihoods. This region is part of one of the most biodiverse areas on Earth and is also exposed to high pressure from deforestation that threatens the ecosystems as well as the well-being of local populations.

5. Aspects of heterogeneity : effects of clear-cutting and post-harvest extraction of bioenergy on plants in boreal forests
Sammanfattning : Abstract. The objectives of this thesis are to evaluate (1) the influence of slope aspect on boreal plant responses to clear-cutting and (2) the effects of post-harvest extraction of bioenergy (logging residues or slash) on plant composition, richness and performance in clear-cuts.
