  1. 1. Effects of nitrogen quality and quantity on weed-crop competition : a greenhouse experiment with Avena sativa and Avena fatua

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Crop Production Ecology

    Författare :Lukas Hallberg; [2019]
    Nyckelord :weed-crop competition; resource pool diversity; soil microbes; weed community;

    Sammanfattning : The intensification of agricultural activities has provided unprecedented increases in crop production. In the light of this development concerns have been raised about its negative environmental impact. High-input farm management has further reduced the weed diversity and shaped weed communities to consist of a few highly competitive weed species. LÄS MER

  2. 2. Coral Fungia fungites- associated microbial communities and their shifts upon anthropogenic disturbances

    Master-uppsats, Uppsala universitet/LimnologiUppsala universitet/Institutionen för biologisk grundutbildning

    Författare :VASILIKI PAPAZACHARIOU; [2019]
    Nyckelord :coral microbiome; Fungia fungites; Microbiology; corals; antibiotics; 16S;

    Sammanfattning : One of the main focus of coral reef ecology has been to shed light on the importance of all microbial members of coral holobiont and how their interactions contribute to the coral’s resilience. However, knowledge is lacking about the composition of microbial communities inhabiting the surface mucus layer of corals including Fungia fungites, a species that lives under stressful conditions close to fish farms in Vietnam.

  3. 3. Probiotics : how does it affect our health?

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Julia Abrahamsson; [2018]
    Nyckelord :probiotics; microbiota; intestinal microbiota; probiotic mechanism of action; irritable bowel syndrome; IBS; microbial ecology; gut microbiota;

    Sammanfattning : The human body consists of about 10 times as many bacteria as our own body cells. Only the gastrointestinal tract can hold up to 400 different bacterial species, where the majority of the bacteria are concentrated to the large intestines. LÄS MER

  5. 5. Rhizosphere Priming and Methane Oxidation in Agricultural Soil - Effect of Land Use on Atmospheric Concentrations of CO2 and CH4 and Climate Change

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Esben Øster Mortensen; [2017]
    Nyckelord :The Priming Effect; Rhizosphere; Methane Oxidation; Land Use; Agriculture; Soil Ecology; Microorganisms; Climate Change; Atmospheric concentrations of CO2 and CH4.; Earth and Environmental Sciences; Biology and Life Sciences; Agriculture and Food Sciences;

    Sammanfattning : Rhizosphere interactions have high influence on the fluxes of carbon to and from terrestrial ecosystems. One very important part of the rhizosphere interactions is the rhizosphere priming effect (RPE) which is defined as changes in the decomposition rate of soil organic matter (SOM) in response to labile organic carbon input from plant roots.
