  2. 1. Coupled processes in seasonally frozen soils : Merging experiments and simulations

    Author : Mousong Wu; Per-Erik Jansson; Bjorn Klove; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Frozen soil; Coupled transport; Energy balance; Uncertainties; Merged study; 冻土；水热盐运移；耦合关系；水热平衡；不确定性; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : Soil freezing/thawing is of importance in the transport of water, heat and solute, with coupled effects. Due to complexity in soil freezing/thawing, uncertainty could be influential in both experimentation and simulation work in frozen soils. READ MORE

  4. 2. Mid-Holocene mineral dust deposition in raised bogs in southern Sweden : Processes and links

    Author : Jenny Sjöström; Malin Kylander; Carl-Magnus Mörth; Bindler Richard; Lisa Belyea; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Paleodust; peat; geochemistry; mineralogy; REE; Holocene; peat accumulation rates; paleostorms; Marine Geology; maringeologi;

    Abstract : Atmospheric mineral dust is a key component of the climate system, which affects insolation, brings nutrients to marine and terrestrial ecosystems, and acts as a cloud condensation nuclei. To reconstruct past patterns in terrestrial dust deposition natural archives may be utilized, such as loess, dunes, lakes, and peat bogs. READ MORE

  5. 3. Dynamics of ecological communities in variable environments : local and spatial processes

    Author : Linda Kaneryd; Bo Ebenman; Peter Münger; Michael S. Fowler; Linköpings universitet; []
    Keywords : ;

    Abstract : The ecosystems of the world are currently facing a variety of anthropogenic perturbations, such as climate change, fragmentation and destruction of habitat, overexploitation of natural resources and invasions of alien species. How the ecosystems will be affected is not only dependent on the direct effects of the perturbations on individual species but also on the trophic structure and interaction patterns of the ecological community.

  7. 5. Coupled Hydrological and Microbiological Processes Controlling Denitrification in Constructed Wetlands

    Author : Johan Kjellin; Anders Wörman; Sara Hallin; Barbro Ulén; Björn Klöve; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Constructed wetland; Residence time; water flow modeling; denitrification rate; Tracer experiment; denitrifying bacteria community structure; Water in nature and society; Vatten i natur och samhälle;

    Abstract : Treatment wetlands play an important role in reducing nitrogen content in wastewater and agricultural run-off water. The main removal process is denitrification and the removal efficiency depends on the hydrological and microbiological features of the wetland, especially in terms of water residence times and denitrification rates.
