1. Effects of climate on phenology, flowering, and berry production of boreal forest understory plants
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : Climate is changing faster than it was predicted before and consequently its impact is highly visible on many types of ecosystems globally. Effects of changing climate on forests and the environment are leading to threats for all sorts of ecosystems. LÄS MER
2. Spatial downscaling of gridded soil moisture products using optical and thermal satellite data: the effects of using different vegetation indices
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Soil moisture (SM) plays an important role in the exchange of heat and water between the surface and atmosphere, impacting water and energy cycles and the climate. Satellite remote sensing offers a global-scale estimation of SM; however, the coarse resolutions of satellite SM products, typically ranging from 25-50 km, are unsuitable for regional analysis.

3. Optimal foraging in an Arctic herbivore : How does the foraging behaviour of Svalbard reindeer (Rangifer tarandus platyrhynchus) respond to seasonal changes from summer through autumn of the Arctic tundra?
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Foraging decisions of large herbivores can be affected by many factors and have great effect on both above- and below-ground ecosystems. Here, I determine to which degree temporal (seasonality), or spatial (habitat) factors influence the foraging behaviour of Svalbard reindeer (Rangifer tarandus platyrhynchus) and asses if small-scale foraging behaviour correlates with an animals’ patch residence time.

4. Impact of Sea Surface Temperature and Salinity on Phytoplankton blooms phenology in the North Sea
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Various environmental forcings can affect phytoplankton blooms, resulting in changes in bloom timing and abundance, which can have many far-reaching consequences. Understanding bloom phenology is crucial to predict and counter any potential harmful changes. LÄS MER
5. Körsbärsträd i ett förändrat klimat : konsekvenser av ett varmare svenskt vårvinterklimat för körsbärsträdens blomning
Kandidat-uppsats, SLU/Dept. of Urban and Rural DevelopmentSammanfattning : Körsbärsblom är för många ett tydligt tecken på att våren är här. Den vackra blomningen är populär hos många och kanske är det anledningen till att körsbärsträd är så vanligt förekommande i svenska städer. LÄS MER
