  1. 1. Global Warming Induced by Oceanic Anoxic Event 1a Had a Pronounced Impact on the Early Cretaceous Terrestrial Vegetation of Southern Sweden

    Master-uppsats, Uppsala universitet/Paleobiologi

    Författare :Marcos Amores; [2022]
    Nyckelord :palynology; spore-pollen; biostratigraphy; oceanic anoxic event 1a; high-latitude; Early Cretaceous;

    Sammanfattning : The Mesozoic is punctuated by several rapid global warming events that are marked by the worldwide deposition of organic-rich marine sediments. These events, known as oceanic anoxic events (OAEs), are characterised by intervals where the worldwide carbon cycle suffers a disruption due to major palaeoceanographic and climatic shifts, leading to anoxic marine environments and the creation of black shales.

  3. 2. Identification and quantification ofmicrobiological risks in board production : A study of ATP bioluminescence and redox potential

    Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik

    Författare :Claudia Bartos; [2022]
    Nyckelord :ATP bioluminescense; redox potential; bacillus; board production;

    Sammanfattning : Stora Enso is a well-established provider of renewable solution packaging and board materials.Board products for liquid packaging and folding cartons for food are particularly sensitive tothe microbiological contaminants. In the manufacturing process, microbiological growth occursdue to environmental favourable conditions. LÄS MER

    Sammanfattning : Skuggbräken är en akut hotad ormbunke med en enda känd lokal på Söderåsens Nationalpark, i Skåne. Detta är ett förarbete för att kunna utveckla en bevarandeplan för arten och kunna bevara populationen i odling, ex situ. LÄS MER

  5. 4. A window to the future of Sweden’s pine forestry? : development of declining Scots pine after a severe drought and the presence of Diplodia sapinea

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

    Författare :Matilda Stein Åslund; [2020]
    Nyckelord :Pinus sylvestris; Scots pine; Diplodia sapinea; Sphaeropsis sapinea; Diplodia pinea; drought; climate change;

    Sammanfattning : Swedish forestry is dominated by uniform conifer stands, a structure generally more susceptible to biotic and abiotic stressors. Among the agents causing forest decline, pathogenic fungi have the most substantial impact. LÄS MER

  7. 5. Arbuscular mycorrhiza in landrace and modern wheat : its impact on plant performance and how it is influenced by plant breeding and modern cropping practices

    Kandidat-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Klara Yngve; [2020]
    Nyckelord :arbuscular mycorrhiza; landrace varieties; modern cultivars; wheat; conventional cropping systems; organic cropping systems;

    Sammanfattning : Modern agriculture has a negative impact on climate and environment and is challenged by climate change. A transition to a more sustainable, secure and yet high food production is necessary. Landrace cereals attract attention for their ability to sustain nutrient deficiency, drought and harsh climate conditions. LÄS MER
