  4. 18. Forest fire drives long-term community changes of wood-decaying fungi in a boreal forest archipelago

    Master-uppsats, Mittuniversitetet/Avdelningen för naturvetenskap

    Författare :Mikael Gudrunsson; [2013]
    Nyckelord :wood-decaying fungi; polypores; species richness; species composition; fire history; disturbance; spatiotemporal dynamics; forest succesion; species-area relationship; dead wood; boreal forest;

    Sammanfattning : Conservation of wood-decaying fungi requires improved knowledge about the long-term effects of forest management; regarding habitat loss, fragmentation and fire suppression. To better understand such effects, I examined the influence of area, isolation, fire history and forest stand characteristics on communities of wood-decaying fungi. LÄS MER
