  3. 2. Ectomycorrhizal Fungal Mycelial Dynamics and its Role in Forest Soil Carbon Cycling

    Författare :Andreas Hagenbo; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Most boreal tree species rely on root-associated ectomycorrhizal fungi for nutrient acquisition, in exchange the trees allocate part of their photosynthetically fixed carbon (C) to these fungi. This has a feedback on soil C dynamics as mycorrhizal fungi are important in regulating soil C cycling and storage. LÄS MER

  4. 3. Carbon stocks and fluxes in a young Siberian larch (Larix sibirica) plantation in Iceland

    Författare :Brynhildur Bjarnadottir; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; interannual variability; carbon balance; Larix sibirica; afforestation; stock-change method; carbon sequestration; eddy covariance; biomass functions;

    Sammanfattning : The understanding of how forests function with respect to carbon (C) balance and its interaction with the climate system is a fundamental question in climate change research. Another important question is how large the sink for CO2 is in northern forests and how it varies with forest type, management, stand age and with external factors, such as climate variability.
