  2. 16. 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

  6. 19. Forests and Greenhouse gases. Fluxes of CO2, CH4 and N2O from drained forests on organic soils

    Author : Karin von Arnold; Leif Klemedtsson; Mats Nilsson; Björn Hånell; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Greenhouse gases; GHG; fluxes of CO2; CH4; drained forests; organic soils; Skogsbotanik; miljöaspekter; växthusgaser; Water in nature and society; Vatten i natur och samhälle;

    Abstract : One of the largest environmental threats believed to be facing us today is global warming due to the accumulation of green house gases (GHG). The concentrations of GHG in the atmosphere are a result of the net strength of different sinks and sources. READ MORE

  7. 20. Ecology of nematophagous fungi in agricultural soils

    Author : Lotta Persmark; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic farming; Fungistasis; Competition; Bacteria; Conidial traps; Rhizosphere; Seasonal variation; Distribution; Endoparasitic; Nematode; Nematode-trapping; Ecology; Ekologi;

    Abstract : Nematophagous fungi possess various mechanisms for infecting nematodes, and are either obligate parasites or facultative saprophytes. Nematophagous fungi have a potential as biological control agents against plant- and animal-parasitic nematodes. READ MORE
