Challenging conventional carbon wisdom : a climate driven vegetation shift from spruce to beech may not change the size of the carbon pool in southeast Norwegian forest soils
Ransedokken, Yngvild (Master thesis, 2016-08-31)Forest soils represents the largest terrestrial carbon (C) pool and thus play a critical role in the global C cycle. Predicted climate change is expected to change the size of forest soil C pools by driving a shift in ... -
Decomposition of Beech and Spruce Litter in Neighbouring Beech and Spruce Forests
Verne, Ingrid Kleppenes (Master thesis, 2017)Climate change is expected to cause a transformation from spruce to beech dominated forests in a large part of southeast Norway. A shift in dominating tree species may have a large effect on the factors controlling the ... -
Decreases of carbon and nitrogen in the soils of a 20-year chronosequence of restored wetlands, Washington State, USA
Kroe, Colleen Suzanne (Master thesis, 2016-09-02)Freshwater wetland restoration is intended to replace both area and function as part of compensatory mitigation, including restoration of biogeochemical soil processes. This study examined the amount of carbon (C) and ... -
En brannhistorisk undersøkelse på Varaldskogen
Bråthen, Martin (Master thesis, 2016-08-15)Sammendrag: Stammeskiver fra stubber etter hogst og levende og døde furutrær med brannlyrer ble samlet inn fra fem innsamlingsfelt (300-400 daa) for å forklare brannhistorien på Varaldskogen (50 km2) sørøst i Norge. En 730 ... -
Establishment, survival and dispersal limitations of pioneer plants in a Norwegian glacier foreland as revealed by seed sowing, transplantation and seed bank experiments
Strømme, Anne-Sofie Bergene (Master thesis, 2016-09-02)Glaciers are melting and retreating on a global scale due to climate change. Rapid glacier retreat leave behind large areas of barren ground, in which primary succession and plant establishments can start. However, a typical ... -
Local pollen analysis in a boreal forest setting : vegetation and land-use history at the summer farm Finnerudseter in south-eastern Norway
Hertzberg, Maria Knagenhjelm (Master thesis, 2016-07-27)Traditional cultural landscapes are threatened in Europe due to changed land-use practices. However, the historical extent of this human land-use practice is not yet fully known. This thesis describes the vegetation history ... -
Small-scale spatial variation in soil properties within an old-growth European beech forest and two Norway spruce forests
Thomassen, Eivind (Master thesis, 2016-09-02)The aim of this study was to investigate species related differences in soil carbon and nitrogen concentration, pH and condensed tannin content in topsoil’s in Norway spruce (Picea abies) European beech (Fagus sylvatica) ... -
Treeline dynamics in Trillemarka - Rollagsfjell
Mortensen, Adrian (Master thesis, 2016-09-02)The environmental effects that determine the altitude of the tree line have been discussed for a long time. Alpine ecosystems are known to be particularly sensitive to climate warming, and both biotic interactions as well ...
