    Sammanfattning : The vertical distribution of the nutrient uptake of Norway spruce (Picea abies (L.) Karst.), European beech (Fagus sylvatica L.) and pedunculate oak (Quercus robur L. LÄS MER

  3. 2. Impact of root and mycorrhizal exudation on soil carbon fluxes : influence of elevated CO2 and metals

    Författare :Emma M. Johansson; Patrick van Hees; Bert Allard; Phil Ineson; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amino acids; 13C; carbon cycle; ectomycorrhiza; elevated CO2; exudation; DOC; LMWOA; metal stress; monosaccharides; oxalate; Pinus sylvestris; saprotrophic fungi; soil respiration; NATURAL SCIENCES; NATURVETENSKAP; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

    Sammanfattning : The thesis concerns the behavior of root and ectomycorrhizal (ECM) exudates. In particular, the dynamics of soluble low molecular weight (LMW) organic compounds such as organic acids (LMWOAs), amino acids, monosaccharides, and dissolved organic carbon (DOC) have been studied.

  4. 3. The use of molecular markers for identifying species diversity and functional variation of ectomycorrhizal fungi

    Författare :Jenny Hedh; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ectomycorrhiza; molecular markers; Paxillus involutus; ITS region; phylogenetic species; host compatibility; gene expression; CGH;

    Sammanfattning : Ectomycorrhiza (EM) is a symbiosis between soil living fungi and the roots of woody plants. EM fungal communities are important in forest nutrient cycling, they are species rich and their structures vary between habitats and over time. LÄS MER

  5. 4. Effects of forest fertilization on soil microorganisms

    Författare :Kristina Arnebrant; Biologibiblioteket; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; forest soil; nitrogen fertilization; microfungi; ectomycorrhiza; ATP; microbial biomass; nitrogen translocation; pine; alder; Frankia;

  7. 5. Colonization processes of soil fauna and mycorrhizal fungi

    Författare :Dagmar Gormsen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; abandonment; land use; ectomycorrhiza; arbuscular mycorrhiza; lumbricid earthworms; Acari; soil fauna; collembola; Djurekologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Colonization consists of two parts, a dispersal phase followed by establishment and reproduction at a new site. Dispersal behaviour influences survival and the access to resources and mates of individuals and is thus closely linked to an organism's fitness. LÄS MER
