  2. 21. Hydrological aspects of the carbon balance in a boreal catchment: A model study

    Author : Alla Yurova; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cartography; pedology; geomorphology; Physical geography; boreal peatland; dissolved organic carbon; ecohydrology; model; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Abstract : AbstractThe cycling of carbon in its gaseous, solid and dissolved forms is of central importance to ecosystem science, particularly, when the natural carbon cycle has been perturbed by human activity. Mathematical models are commonly used to asses and predict global and regional patterns of terrestrial carbon exchange. READ MORE

  4. 22. Nutrient balance and salinity stress in arbuscular mycorrhizal fungi

    Author : Edith Hammer; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inoculum; Glomalin; Fatty acids; Osmolyte; Organic matter; K; Na; Salinity; Symbiotic exchange; Phosphorus P; Carbon C; PIXE; Arbuscular mycorrhizal fungi; Rhizobium;

    Abstract : Earth’s primary production depends to a considerable extent on the mycorrhizal symbiosis, since mycorrhizal fungi supply their host plant with important mineral nutrients. I examined the influence of different nutrient regimes on the fungal partner in the arbuscular mycorrhizal symbiosis. READ MORE

  5. 23. Cryogenic soil processes in a changing climate

    Author : Marina Becher; Jonatan Klaminder; Johan Olofsson; Jan Karlsson; Niclas Börlin; Philip Wookey; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-sorted circle; Carbon storage; Soil motion; Terrestrial photogrammetry; Cryoturbation; Carbon fluxes; naturgeografi; Physical Geography;

    Abstract : A considerable part of the global pool of terrestrial carbon is stored in high latitude soils. In these soils, repeated cycles of freezing and thawing creates soil motion (cryoturbation) that in combination with other cryogenic disturbance processes may play a profound role in controlling the carbon balance of the arctic soil.

  6. 24. Forest Biomass Production Potential and its Implications for Carbon Balance

    Author : Bishnu Chandra Poudel; Mittuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Forestry and Wood Technology; Skog och träteknik;

    Abstract : An integrated methodological approach is used to analyse the forestbiomass production potential in the Middle Norrland region of Sweden, and itsuse to reduce carbon emissions. Forest biomass production, forest management,biomass harvest, and forest product use are analyzed in a system perspectiveconsidering the entire resource flow chains. READ MORE

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

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

    Abstract : 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. READ MORE
