  1. 16. Seasonal variation in fungal biomass : the effects of soil temperature and moisture in a boreal forest

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Malin Leidefors; [2016]
    Keywords : fungi; biomass; qPCR; temperature; moisture; climate;

    Abstract : Climate change involves a series of events promoted by elevated levels of atmospheric CO2, such as increased temperature and changes in seasonal precipitation patterns, soil temperature, moisture and nutrient availability. Soils in boreal forests are often well-drained and not underlain by permafrost, which makes boreal forests susceptible to droughts. READ MORE

  3. 17. Värdspecifitet och diversitet av svampendofyter hos Fraxinus excelsior och Acer pseudoplatanus

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Alva Anderberg; [2016]
    Keywords : endofyter; Fraxinus excelsior; ask; Acer pseudoplatanus; sykomorlönn; svampsamhällen; värdspecifitet; biologisk mångfald;

    Abstract : Efter askskotts- och almsjukans snabba framfart står det klart att svampsjukdomar inom loppet av ett decennium kan få mångfalden i svenska skogar att se fundamentalt annorlunda ut. Skogsbruket och naturvården saknar två av tidigare alternativ för föryngring av ädellövskog. READ MORE

  4. 18. Interactions between Rhizobium, antagonistic bacteria and fungal pathogens in faba bean

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Shirin Akhter; [2014]
    Keywords : Vicia faba; Beneficial plant bacteria; Fungal pathogens; Antagonism; Interactions;

    Abstract : Plant associated micro-organisms such as nitrogen-fixing Rhizobium, and plant growth- promoting rhizobacteria (PGPR) Pseudomonas spp. and Serratia spp. are well recognised for their vital role in soil fertility and plant health. Most cultivated soils contain large populations of such micro-organisms. READ MORE

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

    University essay from Mittuniversitetet/Avdelningen för naturvetenskap

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

    Abstract : 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. READ MORE

  6. 20. Variation in fungal endophyte communities of pedunculate oak (Quercus robus L.) : spatial, temporal and environmental aspects

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Marta Agostinelli; [2012]
    Keywords : Pedunculate oak; Quercus robur; fungal communities; neighboring effect; endophytes;

    Abstract : Fungal endophytes are a taxonomically and ecologically heterogeneous group of ubiquitous intercellular fungi that live part of their life within the tissues of the plants without causing apparent harm to the host. They may contribute to the stress tolerance and resistance of the plants, and endophytes may also be involved in decomposition processes. READ MORE
