  1. 1. The diversity of fungi in coniferous forests and mixed forests

    Master-uppsats, Karlstads universitet

    Författare :Ida Asplund; [2023]
    Nyckelord :Forest type; coniferous forest; mixed forest; fungi; fungal diversity; mycorrhiza; saprotrothic fungi; parasites; parasitic fungi; Skogstyp; barrskog; blandskog; svampar; svampdiversitet; svampmångfald; mykorrhiza; saprotrofiska svampar; parasiter; parasitiska svampar;

    Sammanfattning : The fungal domain has one of the highest biodiversities among eukaryotes and species within the domain fill important ecological roles, such as mutualistic mycorrhiza, decomposers, parasites and pathogens. The development of forest ecosystems and their related processes has not only been linked to fungal diversity but the composition and abundance of fungi benefits the abundance and diversity of other species as well.

  3. 2. Biologisk bekämpning av rotgallnematoderna Meloidogyne chitwoodi & Meloidogyne fallax

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Ellen Johansson; [2022]
    Nyckelord :Växtparasitära nematoder; Sedentära nematoder; Tillsättande biologisk bekämpning; Pasteuria spp.;

    Sammanfattning : Bland de växtparasitära nematoderna är släktet rotgallnematoder ett av de ekonomiskt sett mest betydelsefulla. I Sverige har ett flertal arter av rotgallnematoder påträffats och bland de som senast påträffats hör Meloidogyne chitwoodi och M. fallax som upptäcktes i Sverige år 2017 respektive 2018. Meloidogyne chitwoodi och M. LÄS MER

  4. 3. Interactions between some plant-parasitic nematodes and Rhizoctonia solani in potato fields

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Pia Björsell; [2015]
    Nyckelord :Rhizoctonia solani; Pratylenchus; Trichodoridae; Globodera; synergistic interactions; disease complex; Solanum tuberosum; spatial distribution; stem canker;

    Sammanfattning : The pathogenic fungus Rhizoctonia solani causes major economic losses for potato producers in Sweden. The producers, as well as advisors, have reported possible increases in severity of R. solani when free-living plant parasitic nematodes are present and active. LÄS MER

  5. 4. Lichen decline in areas with increased nitrogen deposition might be explained by parasitic fungi : A survey of parasitic fungi on the lichen Alectoria sarmentosa after 4 years of nitrogen fertilisation

    Kandidat-uppsats, Institutionen för ekologi, miljö och geovetenskap

    Författare :Caspar Ström; [2011]
    Nyckelord :parasitic fungi; lichen diversity; Alectoria sarmentosa; nitrogen deposition;

    Sammanfattning : Nitrogen (N) deposition in Europe has recently increased and is expected to continue to increase in the future. There is a well-documented decline in lichen diversity with higher N availability, although the mechanisms behind this are poorly known. In this study, I tested whether attacks by fungal parasites increase with higher N deposition. LÄS MER
