1. Greenhouse Gas Fluxes and Carbon Sequestration in Young Norway Spruce Stands : The Effects of Fertilization
Abstract : The enormous challenge of climate change is discussed and debated today because of its major impact on life on Earth. The forests have an important role to play as the plants absorb carbon dioxide (CO2) from the atmosphere through their photosynthesis and the growing tree retain carbon (C). READ MORE

2. Direct and indirect pressures of climate change on nutrient and carbon cycling in northern forest ecosystems : Dynamic modelling for policy support
Abstract : Northern forest ecosystems play an important role in mitigating climate change by sequestrating carbon (C), while additionally providing and regulating other ecosystem services. A majority of the Swedish environmental quality objects (EQOs) that guide Swedish environmental policy and management are associated with the forest, and they have proven difficult to achieve.

3. Forest-Fuel Systems : Comparative Analyses in a Life Cycle Perspective
Abstract : Forest fuels can be recovered, stored and handled in several ways and these different ways have different implications for CO2 emissions. In this thesis, comparative analyses were made on different forest-fuel systems. The analyses focused on the recovery and transport systems. READ MORE

5. Perturbance and Stimulation : using Nitrogen Addition and High-Throughput Sequencing to Study Fungal Communities in Boreal Forests
Abstract : Fungal communities are major players in globally important nutrient cycling processes, and form symbioses with most terrestrial plants. In the nitrogen (N) limited Swedish boreal forest, ectomycorrhizal (EcM) fungi colonize most roots of the economically important and stand dominating conifer species, Norway spruce (Picea abies) and Scots pine (Pinus sylvestris), with significant implications for tree nutrition and decomposition processes.
