1. Fosfors omsättningstid i jord med metoden 33P inkubationsexperiment kombination med isotop utbytes kinetik (IEK) med 33P
Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaperSammanfattning : Fosfor är en begränsad resurs på jorden, i vissa länder går det att finna fosfor naturligt i fosfat rikt berg. För att utnyttja den mängd fosfor som finns på jorden på bästa möjliga vis, är det viktigt att få en djupare förståelse för fosfor dynamiken i jord- och växtsystem. LÄS MER
2. Clear-cut Effects on Snow Accumulation and Evapotranspiration in a Boreal Catchment in Northern Sweden
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : The aim of this thesis was to investigate the processes behind an unexpected runoff behaviour after a clear-cut in a boreal forest in northern Sweden (Balsjö). The risks of increased flooding, erosion, nutrient leakage and changes in the local ecosystems are some reasons why it is important to fully understand the effect of clear-cuts on the water balance.

3. Stem injection of different nitrogen forms into young Norway spruce
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Ecology and ManagementSammanfattning : This master thesis has been a pilot study preceding a forthcoming project of a larger scale with the long term objective to separate the direct effect of added nitrogen on soil processes from indirect effects via trees. The aim of this study has been to investigate the allocation of nitrogen following direct injection of liquid solutions into the xylem of 40 year old Norway spruce. LÄS MER
4. Carbon balance of coniferous forests in response to different harvesting strategies : a model based analysis
Master-uppsats, SLU/Dept. of EcologySammanfattning : The aim of this study was ultimately to suggest a harvesting strategy for northern coniferous forests that would be the best choice of carbon management for optimising carbon storage regarding the concerns of both wood production and carbon stored in the forest pools not harvested.For two climatic diverse sites in Sweden, Asa (57°08'N, 14°45'E) and Flakaliden (64°07' N19°27'E), a comparison has been made between three different forest management scenarios by use of a process-based modelling approach.
