1. Forest fertilization does not cause any long-term effects on tree growth or vegetation composition
Master-uppsats, SLU/Dept. of EcologySammanfattning : Forest fertilization is considered one of the most effective management options to improve forest productivity. In Fennoscandia, nitrogen (N) fertilization has been practiced for over 50 years and is normally added in the form of granules of NH4NO3 at least 15 years prior to the final harvest. LÄS MER
2. REINDEER GRAZING IN A NORTHERN BOREAL FOREST : Seasonal and reindeer-induced changes in nutrient availability and soil temperature
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Soil nutrient availability is a key component to understanding the boreal ecosystems, as it directly relates to plant productivity and ecosystem diversity. There is however little known about how the nutrient availability changes seasonally in the boreal forest. LÄS MER
3. Relating the impacts of regenerative farming practices to soil health and carbon sequestration on Gotland, Sweden
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : Land degradation, greenhouse gas emissions and biodiversity loss through agriculture are some of the greatest challenges we are facing today. Fertile and productive soils are the basis of life on this planet and need to be protected and restored to support a growing population and lower negative impacts of climate change. LÄS MER
4. Influence of land cover changes on organic carbon and organic nitrogen concentrations in Swedish rivers
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : There is increasing pressure on freshwater systems due to excessive nutrient loading by anthropogenic sources. In Sweden, freshwaters have become browner due to increasing exports of organic matter from soils into streams, rivers, and lakes. LÄS MER
5. Effects of wild boar (Sus scrofa) on soil processes and tree growth
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Wild boars (Sus scrofa) have increased rapidly in population size and home range since their reintroduction to the Swedish fauna. Through their rooting behaviour, the boars can cause great disturbance to the ecosystem. LÄS MER
