21. Tillväxtmönster och kvalitet i trädslagsblandade bestånd på höga boniteter : en fallstudie i Snogeholms landskapslaboratorium
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : Historiskt har intresset för trädslagsblandningar i Sverige varierat kraftigt och olika positiva fördelar har framhävts under olika tider. På senare tid är den högre artrikedomen i trädslagsblandade bestånd och en möjlighet att delvis bryta granens dominans i södra Sverige ökat intresset för trädslagsblandade bestånd. LÄS MER
22. Tree species classification using multi-temporal Sentinel-2 data
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Resource ManagementSammanfattning : The Sentinel-2 program provides the opportunity to monitor terrestrial ecosystems with a high temporal- and spectral resolution. In this study, the utilization of multi-temporal Sentinel-2 imagery and it’s spectral variation due to phenology for classification of common tree species is evaluated at the forest estate Remningstorp in central Sweden.

23. Rätt björk på rätt mark : Visuell identifiering av naturligt föryngrad björk
Kandidat-uppsats, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)Sammanfattning : The silver birch (Betula pendula Roth) and the downy birch (Betula pubescens Ehrh) are the most common broadleaved species in Swedish forests. Both species have a lot in common in appearance and are often misleadingly referred to simply as ”birch”. They have however different requirements and possibilities to grow on different sites.

24. Natural regeneration on clear cuts in Southern Sweden : how fencing, soil treatment and distance from broad-leaved forest affect tree regeneration and ground vegetation
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : The forests of Europe have seen a dramatic shift in structure, species composition and area coverage in the last centuries. Large areas previously covered by a mixed broad-leaved forest are now used for agriculture or other land uses. LÄS MER
25. Uptake of per- and polyfluoroalkyl substances by plants
Master-uppsats, SLU/Dept. of Aquatic Sciences and AssessmentSammanfattning : The extensive use of per- and polyfluoroalkyl substances (PFASs) as surfactants in, for example textiles,cookware and aqueous firefighting foams (AFFFs) during the last decades has resulted in widespread environmental contamination. Due to the persistent and bioaccumulative characteristics of PFASs, they are ubiquitously found in the environment, wildlife and humans. LÄS MER
