  1. 1. External Mycelia of Mycorrhizal Fungi - responses to elevated N in forest ecosystems

    Författare :Lars Ola Nilsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ericoid; arbuscular; mycorrhiza; nitrogen; deposition; fertilisation; nitrate leaching; retention; field; forest; Quercus; deciduous; Plant ecology; Växtekologi; mykologi; virologi; bakteriologi; mycology; Microbiology; External mycelia; ectomycorrhiza; Mikrobiologi; bacteriology; virology;

    Sammanfattning : Most plants live in symbiosis with mycorrhizal fungi. Mycorrhizal roots constitute the interface between the plant and the soil, and almost every fine root of forest trees in nitrogen-limited boreal and temperate forests is colonised by ectomycorrhizal (EM) fungi. LÄS MER

  4. 3. Forest restoration on degraded lands in Laos

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

    Sammanfattning : Deforestation and land-use change have been, and still are, major threats to biodiversity and ecosystem services in the tropics, and forest areas are being lost at high rates in many countries in Southeast Asia, including Laos. Progress in the development and application of forest policies and programs, coupled with increasing trends to end damaging practices associated with swidden cultivation have created opportunities to restore forests.

  5. 4. Forest Biomass Production Potential and its Implications for Carbon Balance

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

    Sammanfattning : 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. LÄS MER

  7. 5. Non-industrial private land use and forest management : landscape and policy perspectives
