1. 1. Modelling effects of climate change and forestry on weathering rates and base cation cycling in forest soils

   Författare :Veronika Kronnäs; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; weathering; forest; biogeochemistry; Dynamic Modelling; ForSAFE;

   Sammanfattning : Base cations are important in forest soils as nutrients for vegetation and protection against soil acidification. Today, base cations have been lost from soils through acidification and forest harvesting. With low levels in soils, temporary situations of deficiency could occur. LÄS MER

3. 2. Modeling nutrient cycling and sustainable forest growth in a changing world

   Författare :Patrik Wallman; LUCSUS; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; nutrients; sustainability; ForSAFE; Chemical technology and engineering; forestry technology; forestry; Silviculture; system dynamics; forest growth models; dynamic modeling; Kemiteknik och kemisk teknologi; skogsbruk; skogsteknik; Skogsvetenskap;

   Sammanfattning : It took 70-80 years to realize the width of the impact of industrialization on the forest ecosystems since a forest ecosystem is a "slow system" as seen from a human perspective. An anticipated future climate change and increasing carbon dioxide and ozone levels will change the conditions even more with time and the widely used statistical forest growth models will not be applicable anymore.

4. 3. Modelling nutrient transport from forest ecosystems to surface waters : The model ForSAFE-2D

   Författare :Giuliana Zanchi; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; forest; dynamic modelling; hydrology; biogeochemistry; ecosystem service;

   Sammanfattning : Forests provide multiple products and services which are all are linked to water resources. Trees need water to grow and, at the same time, they change the quality and the quantity of runoff by modifying water and nutrient cycling. LÄS MER

5. 4. DYNAMIC MODELLING OF BIOGEOCHEMICAL PROCESSES IN FOREST ECOSYSTEMS

   Författare :Salim Belyazid; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Naturvetenskap; marklära; Silviculture; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik; Natural science; Lantbrukshydrologi; Soil Science; agricultural hydrology; Växtekologi; Forest Soil Acidification; Plant ecology; Plant biochemistry; Forest Growth; Vegetation biodiversity; Carbon Sequestration; Nitrogen Leaching; Miljökemi; Dynamic Modelling; Växtbiokemi; Environmental chemistry;

   Sammanfattning : Forests in Sweden are undergoing rapid and considerable changes regarding both management methods and environmental conditions. To understand the effects of these changes and to be able to predict impending changes in forest ecosystems, a holistic understanding of the processes governing the ecosystem is needed. LÄS MER

7. 5. Dynamic modelling of the forest ecosystem: Incorporation of the phosphorus cycle

   Författare :Lin Yu; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dynamic modeling; forest ecosystem; phosphorus cycle;

   Sammanfattning : The forest ecosystem provides and regulates many important ecosystem services, such as soil and water protection, timber production, and climate regulation. It has been influenced by changes induced by humans, for example, our increasing demand for timber and bioenergy, the increase in nitrogen (N) deposition and CO2 concentrations due to industrialization, and climate change which has caused an increase in global temperature and extreme events such as storms.
