  1. 16. Secrets of the Seeds : exploring the relationship between seed morphology and seed quality in Lepidium campestre, a novel oil crop for Northern Sweden

    Kandidat-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Ludvig Pettersson Landgren; [2023]
    Nyckelord :Lepidium campestre; field cress; oil crop; plant breeding; domestication; seed morphology; seed colour; seed analysis; Northern Sweden; glucosinolate;

    Sammanfattning : This study set out to explore relationships between seed morphology and qualitative traits in field cress, Lepidium campestre, with the goal of assisting the breeding process of this crop under domestication. A collection of seeds of L. campestre as well as related species was analysed for weight and size using a MARViN seed analyser. LÄS MER

  3. 17. 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.

  4. 18. The gut microbiome and nausea in pregnancy

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Clàudia González Valdivia; [2023]
    Nyckelord :Bioinformatics; Microbiome; Metagenomics; Genome analysis; Genetics;

    Sammanfattning : Nausea and vomiting are among the most common symptoms of early pregnancy. Its most extreme form Hyperemesis gravidarum often requires hospitalization and has been linked as a risk factor of perinatal depression. LÄS MER

  5. 19. Föryngring med hägn : effekten av viltbete på självföryngrad ädellövskog i tre skånska naturreservat

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Håkan Ramberg; Kaj Sjöqvist; [2023]
    Nyckelord :Bokskog; naturlig föryngring; betesbegärlighet; viltbete; strukturförändring;

    Sammanfattning : Ädellövskogens artsammansättning styrs av flera naturliga processer, en av dessa processer är viltbete. Bete kan leda till att trädslagsfördelningen förändras och att föryngring blir problematiskt, speciellt i områden med stora viltstammar och för de mer betesbegärliga trädarterna. LÄS MER

  7. 20. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Alexina Brännlund; [2023]
    Nyckelord :Experimental warming; Subarctic tundra mosses; Productivity; Ecosystem respiration; Decomposition;

    Sammanfattning : Long-term warming experiments in arctic tundra have resulted in reduced moss cover and increased vascular plant cover. As mosses have a major impact on microclimatic conditions, changes in community composition can potentially alter direct and indirect drivers of productivity and decomposition, which are low in arctic ecosystems.
