1. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Long-term warming experiments in arctic tundra have resulted in reduced moss cover and increased vascular plant cover. As mosses have a major impact on microclimatic conditions, changes in community composition can potentially alter direct and indirect drivers of productivity and decomposition, which are low in arctic ecosystems.

2. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. LÄS MER
3. Evaluation of the effect of conflict on fire and GPP in Ukraine
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The war in Ukraine in 2022 has caused environmental damages on different scales which come with their own challenges. One of the factors that can cause environmental damage is vegetation fire. LÄS MER
4. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. LÄS MER
5. Hur arbetar mindre kommuner i Sverige med implementeringen av miljöhänsyn vid offentlig upphandling? : En kvalitativ intervjustudie av mindre kommuner
Kandidat-uppsats, Linnéuniversitetet/Institutionen för management (MAN)Sammanfattning : Bakgrund: Mångmiljardbelopp spenderas varje år i onödan på offentliga upphandlingar, delvis på grund av bristande ekonomistyrning. Offentliga upphandlingar beräknas även stå för 28 procent av den totala klimatpåverkan för Sveriges konsumtion. LÄS MER
