21. Effects of forest management on greenhouse gas fluxes in a boreal forest
Sammanfattning : Forest ecosystems cover 31% of the terrestrial land area and store large amounts of carbon in biomass and in soils. The 2015 Paris Agreement recognizes the importance of sinks and reservoirs of greenhouse gases (GHGs) in forests and the importance of enhancing them through sustainable forest management policies.

22. Mycorrhizal guild functions and conservational values in boreal forests
Sammanfattning : 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.

23. The greenhouse gas balance of drained forest landscapes in boreal Sweden
Sammanfattning : Forest drainage has been extensively used to facilitate forest growth in Fennoscandinavia. However, its impact on the ecosystem carbon (C) and greenhouse gas (GHG) balances is limited, particularly in the large area of hemiboreal and boreal Sweden. LÄS MER
24. The importance of small forest set-asides for saproxylic biodiversity at stand- landscape- and regional scales

25. Estimation of Forest Biomass and Faraday Rotation using Ultra High Frequency Synthetic Aperture Radar
Sammanfattning : Synthetic Aperture Radar (SAR) data in the Ultra High Frequency (UHF; 300 MHz – 3 GHz)) band have been shown to be strongly dependent of forest biomass, which is a poorly estimated variable in the global carbon cycle. In this thesis UHF-band SAR data from the fairly flat hemiboreal test site Remningstorp in southern Sweden were analysed. LÄS MER
