1. Effects of 100 years of drainage on peat properties in a drained peatland forests in northern SwedenMaster-uppsats, SLU/Dept. of Forest Ecology and Management
Sammanfattning : 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. LÄS MER
2. Effects of nitrogen quality and quantity on weed-crop competition : a greenhouse experiment with Avena sativa and Avena fatuaUppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Crop Production Ecology
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
3. Coral Fungia fungites- associated microbial communities and their shifts upon anthropogenic disturbancesMaster-uppsats, Uppsala universitet/LimnologiUppsala universitet/Institutionen för biologisk grundutbildning
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.

4. Microbial community responses to freeze : thaw cycles in active layer soils of permafrost tundra, Disko Island, GreenlandMaster-uppsats, SLU/Dept. of Soil and Environment
Sammanfattning : Permafrost affected soils are a vast pool of Carbon, storing around 1300Pg below the ground. As a result of climate change, permafrost soils that have been frozen for thousands of years are thawing, causing the ancient organic matter to be metabolised by microorgan-isms. LÄS MER
5. Bacterial and fungal responses to drying and rewetting using bronopol or cycloheximide as inhibitorsKandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning
Sammanfattning : Microbial decomposers breakdown soil organic matter, releasing carbon dioxide (CO2) to the atmosphere. This release of CO2 could therefore contribute to future climate change. LÄS MER
