16. Mycorrhizal guild functions and conservational values in boreal forests
Abstract : The immense diversity and biomass of ericoid-, ectomycorrhizal, and saprotrophic fungal guilds in boreal forest soils make them vital components of conservation and ecosystem processes, and in particular, many ectomycorrhizal fungi are considered species of conservation concern. However, amalgamated information on the functions and relationships of soil fungi to perceived forest conservation values, and how inter and intra-guild interactions affect the accretion and decomposition of soil organic matter is lacking.

19. Impacts of climate change on forest management and implications for Swedish forestry : an analysis based on growth and yield models
Abstract : While climate change is expected to increase the growth rates of most tree species in Sweden in the future, during this period, there are also increased risks of tree damage due to various risk factors associated with climate change. Therefore, it is necessary to develop adaptive management measures in order to exploit the benefits of climate change and minimize the damage resulting from these risk factors. READ MORE

20. Vegetation changes on Swedish mires : Effects of raised temperature and increased nitrogen and sulphur influx
Abstract : Since the start of the industrialisation, the deposition of nitrogen and sulphur and the atmospheric concentrations of greenhouse gases have increased. The main objectives of this study were to find how these changes in climate and deposition can change the vegetation of mire ecosystems and the growth of Sphagnumspecies. READ MORE
