1. 16. Boreal Lake Sediments as Sources and Sinks of Carbon

   Författare :Cristian Gudasz; Tranvik Lars; David Bastviken; Susan Ziegler; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boreal lakes; allochthonous; lake sediments; sediment mineralization; bacterial production; bacterial biomass; carbon cycle; Freshwater ecology; Limnisk ekologi; Limnologi; Limnology;

   Sammanfattning : Inland waters process large amounts of organic carbon, contributing to CO2 and CH4 emissions, as well as storing organic carbon (OC) over geological timescales. Recently, it has been shown that the magnitude of these processes is of global significance. LÄS MER

3. 17. The hidden half of the meadow : Interactions between drought, soil carbon, roots and soil microbial communities

   Författare :Daniela Guasconi; Gustaf Hugelius; Sara Cousins; Stefano Manzoni; Petra Fransson; David Johnson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; soil; soil carbon; soil ecology; roots; root traits; microbial communities; grasslands; climate change; drought; land management; compost; naturgeografi; Physical Geography;

   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

4. 18. Carbon Sink or Energy Source : Economic perspectives on future uses of forest resources in Sweden

   Författare :Carl Nolander; Robert Lundmark; Ljusk Ola Eriksson; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

   Sammanfattning : Abstract Forests and the resources they offer have been important for the Swedish economy for a long time, and the forest industry remains a large part of the manufacturing industry even as the economy is becoming more service-based. Forests are also increasingly seen as an important source of biofuels that can be used to reduce the reliance on fossil fuels and to reach the target for a carbon neutral economy by the year 2050.

5. 19. Regional Nutrient Budgets in Forest Soils in a Policy Perspective

   Författare :Cecilia Akselsson; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; geomorphology; Physical geography; Miljökemi; Environmental chemistry; skogsteknik; skogsbruk; Skogsvetenskap; forestry technology; forestry; Silviculture; Näringslära; Nutrition; Växtekologi; policy-making; Plant ecology; regional scale; deposition; eutrophication; carbon sequestration; acidification; Nutrient budget;

   Sammanfattning : Sweden's forests are one of its most important natural resources, as well as being important from ecological and social perspectives. Nutrient sustainability is essential to maintain the production capacity and reduce the effects of acidification and eutrophication. LÄS MER

7. 20. Dissolved organic matter across terrestrial and aquatic systems : sources, chemistry and microbial processing

   Författare :Geert Hensgens; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dissolved organic matter; carbon; leaching; decay; chemistry; terrestrial; aquatic;

   Sammanfattning : The movement of DOM from terrestrial to aquatic systems is a globally significant flux affecting both carbon sequestration and CO2 emissions. Here, DOM dynamics were investigated in terrestrial and aquatic systems within the context of this carbon flux. LÄS MER
