  1. 1. Relations between tree and habitat characteristics and the epiphytic lichen flora on oak : a case study from Lövön, Bohuslän

    Kandidat-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Julia Siegel; [2023]
    Nyckelord :Epiphytic lichens; Tree characteristics; Habitat characteristics; Oak; Biodiversity; Natural values; Light availability;

    Sammanfattning : Oak-rich forests and wooded pastures harbor diverse and distinct epiphytic lichen flora with many rare and threatened species. As these habitats have been subject to a substantial decline and degradation over the past centuries, oak woodlands have progressively come into focus for preservation. LÄS MER

  3. 2. Foliar fungal communities of naturally regenerated and nursery-produced Scots pine (Pinus sylvestris) seedlings

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Sara López Fernández; [2023]
    Nyckelord :Endophytes; high-throughput sequencing; foliar fungi; forest nursery; fungal community; fungal pathogens; metabarcoding; mycobiome; Pinus sylvestris; pine seedlings; Scots pine needles;

    Sammanfattning : Endophytic fungal communities living in leaves of trees can have a significant impact on their hosts,showing both beneficial and detrimental effects. Some mutualistic fungal species protect the host against pathogens or herbivores, while pathogenic species can increase the vulnerability of the host against biotic and abiotic stresses. LÄS MER

  4. 3. Quantity and quality of oaks (Quercus) as suitable habitats for the longhorn beetle species Plagionotus detritus : An inventory study in Stockholm and Uppsala County, Sweden

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Ida Widegren; [2023]
    Nyckelord :Plagionotus detritus; P. detritus; Cerambycidae; Cerambycinae; longhorn beetle; insects; habitat; oak; Quercus; conservation; ecology; endangered; threatened;

    Sammanfattning : The longhorn beetle Plagionotus detritus is associated with newly dead oak wood and is declining throughout its distribution range. In Sweden, P.detritus has displayed one of the most dramatic reductions in distribution recorded for insect species and is near regional extinction. LÄS MER

  5. 4. Phylogenomics of Ascetosporea

    Master-uppsats, Uppsala universitet/Systematisk biologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Harshal Kunal Bhawe; [2022]
    Nyckelord :phylogenetics; ascetosporea; bioinformatics; mussel;

    Sammanfattning : Ascetosporea is a class of poorly studied unicellular eukaryotes that function as parasites of marine invertebrates. These parasites cause mass mortality events in aquaculture species such as oysters and mussels. LÄS MER

  7. 5. Exploring methods for detecting super-spreaders using molecular data : A literature study and case study of VTEC O157:H7 in dairy calves

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Amanda Wallskog; [2022]
    Nyckelord :Super-spreaders; Super-shedders; outbreaker2; phybreak; VTEC O157:H7;

    Sammanfattning : Verotoxin-producing Escherichia coli (VTEC) of serotype O157:H7 is a pathogen causing illness in humans worldwide. The path and nature of transmission from and among cattle is important knowledge when it comes to preventing cases of disease in humans. LÄS MER
