1. Can precommercial thinning be used to create more diversity after planting spruce?
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : Mixed forests will harbour other ecosystem services than a planted coniferous monoculture. This study used early results from a long-term experiment to examine if different precommercial thinning treatments can be used to increase diversity in planted stands of Norway spruce (Picea abies) mixed with high densities of natural regeneration of birch (Betula spp. LÄS MER
2. Machine Learning Prediction of Enzymes’ Optimal Catalytic Temperatures
Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknikSammanfattning : Enzymes that have been genetically engineered to withstand high temperatures are used by industry to make products with less waste and pollution. Different features of protein structure affect the optimal catalytic temperature ("topt") at which enzymes catalyze reactions most efficiently. LÄS MER
3. Analysis of relatedness and genetic diversity in Swedish sheep breeds using medium density (50K) SNP data
Master-uppsats, SLU/Dept. of Animal Breeding and GeneticsSammanfattning : The local Swedish sheep breeds belong to a group of sheep breeds known as North European short-tailed sheep breeds. Evaluation of genetic diversity, relatedness, and population structure of local breeds offers crucial metrics to prevent inbreeding depression, genetic erosion, and crossbreeding between locally adapted and exotic sheep breeds since these occurrences can have detrimental effects and ultimately lead to extinction.

4. If a Tree Falls in the Forest - Three Interventions in the Swedish Forest to Come
Uppsats för yrkesexamina på avancerad nivå, KTH/ArkitekturSammanfattning : Our thesis project consists of three architectural interventions: The Mushroom, The Gnat and The Snake, fitting into a vision of a Swedish forest managed in a more sustainable way. A future in which the practice of clear-felling has been abandoned in favor of alternative methods falling under the umbrella term Continuous Cover Forestry (CCF). LÄS MER
5. Exploring patterns in risk factors for bark beetle attack during outbreaks triggered by drought stress with harvester data on attacked trees: A case study in Southeastern Sweden
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : ABSTRACT Raising temperatures and climate variability have intensified extreme weather events worldwide. These extremes can enhance and trigger possible pest outbreaks. Bark beetle attacks have become a major concern in regions with extensive spruce forest areas. Southeastern Sweden has faced repeated outbreaks resulting in widespread tree loss. LÄS MER
