1. The hidden half of the meadow : Interactions between drought, soil carbon, roots and soil microbial communities
Sammanfattning : Soil is a hidden ecosystem which harbours plant roots and countless microorganisms, vital for sustaining life aboveground. These belowground communities provide essential ecosystem services like soil stabilisation and organic matter decomposition. LÄS MER
2. High-resolution mapping and spatial variability of soil organic carbon storage in permafrost environments
Sammanfattning : Large amounts of carbon are stored in soils of the northern circumpolar permafrost region. High-resolution mapping of this soil organic carbon (SOC) is important to better understand and predict local to global scale carbon dynamics. LÄS MER
3. Phosphorus availability and microbial respiration across biomes : from plantation forest to tundra
Sammanfattning : Phosphorus is the main limiting nutrient for plant growth in large areas of the world and the availability of phosphorus to plants and microbes can be strongly affected by soil properties. Even though the phosphorus cycle has been studied extensively, much remains unknown about the key processes governing phosphorus availability in different environments. LÄS MER
4. Importance of tannins for responses of aspen to anthropogenic nitrogen enrichment
Sammanfattning : Boreal forests are often strongly nitrogen (N) limited. However, human activities are leading to increased N inputs into these ecosystems, through atmospheric N deposition and forest fertilization. LÄS MER
5. The radium distribution in some Swedish soils and its effects on radon emanation
Sammanfattning : The aim of this study has been to clarify how the radiumdistribution in soils affects the radon emanation. Thedistribution of radium, uranium and thorium has been determinedusing sequential extractions. In the study, soils from twodifferent locations were investigated. LÄS MER
