  1. 1. Drought resistance of Ectomycorrhizal fungi in the Suillus genus

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Patricia Salén; [2024]
    Nyckelord :Ectomycorrhiza; drought; Suillus;

    Sammanfattning : Rising instances of drought are causing more tree seedling fatalities post-nursery outplanting. In the face of climate change, fostering resilient forestry practices is imperative for preserving the health and functionality of our forests. LÄS MER

  3. 2. Relatedness and diversity in Swedish local chicken breeds using mitochondrial DNA D-loop sequences and SNP data

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Esther Taiwo Afolabi; [2023]
    Nyckelord :chicken; genetic diversity; mtDNA d-loop; SNP; Swedish local chicken breeds;

    Sammanfattning : Genetic diversity is the variation in genetic information carried by individuals within a species or population. This variability plays a crucial role in enabling species to adapt and survive in changing environments and is essential for evolutionary processes. LÄS MER

  4. 3. A Statistical Approach to Understand the Evolution of Exotic Butterfly Species

    Kandidat-uppsats, KTH/Matematisk statistik

    Författare :Elin Eliasson; Rebecka Haraldsson; [2023]
    Nyckelord :Phylogenetics; Tree reconstruction; COI barcoding; General Time Reversible Model; K80 Model; Evolution; Butterflies; Fylogenetik; Rekonstruktion av träd; COI barcoding; General Time Reversible modell; K80 modell; Evolution; Fjärilar;

    Sammanfattning : The alarming rate at which we see the decline in biodiversity due to human activity has raised concerns about the well-being of our planet. Butterflies which serve as pollinators are an essential part of many ecosystems and sensitive indicators of environmental changes and can provide valuable insight into how ecosystems function and evolve.

  5. 4. Selaginella - phylogeny of the South American species within subgenus Stachygynandrum

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Hedda Ericsson; [2023]
    Nyckelord :;

    Sammanfattning : Selaginellaceae is a family within the lycophytes, and it comprises one genus, Selaginella. They are herbaceous seedless vascular plants found globally, with around 750 species. Selaginella is divided into several subgenera, but there is no classification that is agreed upon. LÄS MER

  7. 5. Identification and expression of genes involved in the arabinoxylan biosynthetic pathway in oat

    Master-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Johan Valeur; [2022]
    Nyckelord :Arabinoxylan; Oat; Gene expression analysis;

    Sammanfattning : Oat is one of the most cultivated cereal crops in the world, and Arabinoxylan (AX) is a dietary fiber in oats with positive health effects. The biosynthetic pathway AX in Oat is still unknown, and which genes are active in its production. Ortholog genes have been identified in oat from other species like rice, wheat, barley, and Arabidopsis. LÄS MER
