1. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?
University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskapAbstract : 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
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : 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. READ MORE

3. Evaluation of the effect of conflict on fire and GPP in Ukraine
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : 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. READ MORE

4. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : 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. READ MORE

5. A comparison of remote sensed semi-arid grassland vegetation anomalies detected using MODIS and Sentinel-3, with anomalies in ground-based eddy covariance flux measurements.
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Remote sensed vegetation biophysical indicators are derived from various sensors and methods and contribute to the quantification of vegetation growth. They are used as inputs to early warning systems for crop yield estimation, thus improving crop management and food security. READ MORE
