  1. 21. Effects of 100 years of drainage on peat properties in a drained peatland forests in northern Sweden

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Mikaela Casselgård; [2020]
    Keywords : ash content; biodiversity; bulk density; carbon; climate; compaction; ditch; drainage; greenhouse gas emissions; groundwater level; isotopes; nitrogen; peatland; restoration;

    Abstract : Natural peatlands provide a small but persistent long-term carbon (C) sink. However, within the last century their extent in Sweden has declined by about 1.5-2.0 million hectares due to drainage activities. READ MORE

  3. 22. Effects of organic matter depletion on fungal communities in a reconstructed boreal forest podzol system

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Katharine Alice King; [2020]
    Keywords : ectomycorrhizal fungi; fungal community structure; fungal diversity; high throughput sequencing; podzol; soil horizons;

    Abstract : The boreal forest biome serves as a valuable resource, both as a source of wood, pulp and biofuel, and as a sink of atmospheric carbon (C). A large proportion of C is sequestered to the soil of the boreal biome, however belowground processes are still poorly understood. READ MORE

  4. 23. Reimagining agriculture with perennial crops : a study on the diffusion of innovation and soil ecosystem services in the new perennial grain Kernza

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Robin Meijer; [2020]
    Keywords : Intermediate Wheatgrass; Kernza; Thinopyrum Intermedium; perennial grain; polyculture; wheat; annual; microbial biomass; soil microbial community structure; PLFA; NLFA; sustainability; agroecology; ecological intensification; innovation;

    Abstract : Perennial crops have been identified as a pathway to implement ecological intensification, which in extent could make agriculture more socio-economically and ecologically sustainable. This is a master thesis in Agroecology – a growing scientific discipline that aims to investigate problems in the food system using a holistic and transdisciplinary approach, incorporating and integrating both natural and social sciences to transform the food system.

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

    University essay from SLU/Dept. of Crop Production Ecology

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

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

    Abstract : 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.
