1. Effect of stand age on soil respiration in managed vs unmanaged Scots pine stands
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : How the forests in Sweden and around the world have been, and are still today, managed is a hot debate. The rotation forestry that is commonly used in Sweden has been the focus of debate regarding whether it is a sustainable management method, and whether it should be changed. LÄS MER
2. Tundra carbon cycling in relation to sea-ice decline in a warming Arctic
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : We set out to investigate whether arctic tundra acted as a sink or source of carbon dioxide (CO2) between 1980-2014 and to relate changes in the net carbon balance to Arctic sea-ice decline. We want to understand how climate change and arctic warming influence arctic carbon cycling. LÄS MER
3. Estimation of Carbon Dioxide emissions from forest soils based on CO2 concentrations
Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskapSammanfattning : Forest soil is an important source of atmospheric CO2. Emission of CO2 from soil is the result of respiration of plant roots and soil organisms (Autotrophic and Heterotrophic respiration). This soil CO2 emission has a variation throughout the year with maximum emissions being in the summer. LÄS MER
4. The effects of site preparation on carbon fluxes at two clear-cuts in southern Sweden
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Clear-cutting is a common forest management practice. It alters the carbon balance of forests by eliminating photosynthesis through canopy removal and affecting autotrophic and heterotrophic respiration. In Sweden, almost 200 000 ha of forest is clear-cut every year and site preparation is carried out on more than 80% of it. LÄS MER
5. Spatial heterogeneity of soil CO2 efflux at ADVEX site Norunda in Sweden
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : This study investigates the spatial variation in soil carbon dioxide (CO2) efflux in a boreal mixed forest mainly dominated by Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies L.) in the ADVEX expermental site in Norunda, in central Sweden.
