  2. 1. Soil Nailing. A Laboratory and Field Study of Pullout Capacity

    Author : Gunilla Franzén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Soil Nailing is a technique for reinforcing soil in situ, increasingly utilised as an economical alternative to conventional earth reinforcing techniques. However, today the design is based on an assumed value of the pullout capacity of nails, which later is verified by pullout tests during the construction, which in turn limits the possibility of optimising the design.

  4. 2. Biomass, community structure and phosphorus uptake of ectomycorrhizal fungi in response to phosphorus limitation and nitrogen deposition

    Author : Juan Pablo Almeida; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phosphorus and nitrogen limitation; nitrogen deposition; ectomycorrhizal fungi; community composition; apatite; Paxillus involutus; Phosphorus and nitrogen limitation; nitrogen deposition; ectomycorrhizal fungi; community composition; apatite; Paxillus involutus;

    Abstract : High levels of nitrogen (N) deposition might result in a transition from N to phosphorus (P) limitation in high latitude forests. Thiscould have fundamental consequences for forest production, nutrient acquisition and nutrient leaching. READ MORE

  5. 3. The functional potential of methane producing and consuming microorganisms in a changing world : Den funktionella potentialen hos mikroorganismer som producerar och förbrukar metan i en föränderlig värld

    Author : Joel White; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Methane; Metagenomics; Peatlands; flux; carbon dioxide; chamber measurements; stable isotope analysis; Eriophorum vaginatum; Calluna vulgaris; climate change; Captured metagenomics;

    Abstract : It’s clear that human activities have heated our climate via the release of anthropogenic greenhouse gases. Recent changes within the earth climate are rapid, intensifying, and unprecedented. READ MORE

  6. 4. Properties and fungal decomposition of iron oxide-associated organic matter

    Author : Zhaomo Tian; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Soil organic matter (SOM) stores the largest quantity of C in terrestrial ecosystems. Most SOM can be decomposed by microorganisms and released as CO2 into the atmosphere. The remaining fraction of SOM can be resistant against microbial decomposition over centuries to millennia. READ MORE

  7. 5. Molecular interactions between quinoa, the biocontrol agent Trichoderma and the pathogen Peronospora variabilis

    Author : Oscar Miguel Rollano Penaloza; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chenopodium quinoa; Peronospora variabilis; Trichoderma harzianum; Molecular interactions; qRT-PCR; RNA-seq; Plant growth promotion; Chenopodium quinoa; Peronospora variabilis; Trichoderma harzianum; RNA-seq; qRT-PCR; molekylära interaktioner;

    Abstract : Plants have developed complex molecular mechanisms to recognize and respond to the different microorganisms present in their surroundings. The most studied response mechanisms are plant defense responses. These defense response mechanisms share many similar components with the plant response mechanisms to beneficial microbes. READ MORE
