1. 1. Effect of stand age on soil respiration in managed vs unmanaged Scots pine stands

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Richard Engholm; [2024]
   Keywords : chronosequence; soil respiration; total respiration; autotrophic respiration; heterotrophic respiration; forestry;

   Abstract : 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. READ MORE

3. 2. Tundra carbon cycling in relation to sea-ice decline in a warming Arctic

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Juliane Glinski; [2022]
   Keywords : sea-ice decline; warming Arctic; earlier growing season; arctic tundra; heterotrophic and autotrophic respiration; climate warming; Earth and Environmental Sciences;

   Abstract : 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. READ MORE

4. 3. Estimation of Carbon Dioxide emissions from forest soils based on CO2 concentrations

   University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

   Author : Dennis Dennis Wilson; [2017]
   Keywords : Key Words: Soil Concentration; Soil CO2 production; Soil Respiration; Seasonal variation.;

   Abstract : 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. READ MORE

5. 4. The effects of site preparation on carbon fluxes at two clear-cuts in southern Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Liisi Nogu; [2014]
   Keywords : eddy covariance; soil CO2 flux; site preparation; physical geography; geography; chamber measurements; Earth and Environmental Sciences;

   Abstract : 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. READ MORE

6. 5. Spatial heterogeneity of soil CO2 efflux at ADVEX site Norunda in Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Bahzad Khaled; [2011]
   Keywords : soil CO2 efflux; spatial variation; depth of the soil; humus thickness; micro topography; stand and forest floor characteristics; mark-CO2-utflöde; rumslig variation; markdjup; humustjocklek; mikrotopografi; trädbestånd; skogsmarkskaraktäristik; Earth and Environmental Sciences;

   Abstract : 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. READ MORE
