1. Natura 2000-områdens roll i omprövningen av vattenkraftens miljötillstånd
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystemSammanfattning : Vattenkraften utgör ungefär 45 % av Sveriges elproduktion och har varit en stabil energikälla med lågt koldioxidutsläpp under lång tid. Med ett allt större inslag av intermittenta energislag i elsystemet, fyller vattenkraften också en viktig funktion med sin reglerförmåga för balansering. LÄS MER
2. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. LÄS MER
3. Mängden död ved i värdekärnor i Söderåsens nationalpark
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : There is a lack of knowledge about the development of the dead wood in former production beech (Fagus sylvatica) forests that have been protected. The present study has been carried out in Söderåsen National Park to compare the distribution of dead wood in relatively unaffected beech forests that have been protected for a long time (A-value cores) and older, previously managed beech forest that has only been protected for 20-30 years (B-value cores).

4. Heritability of methane emission in Swedish Red cattle in northern Sweden
Master-uppsats, SLU/Dept. of Animal Breeding and GeneticsSammanfattning : Dairy cattle contribute a significant proportion of greenhouse gases (GHG), mainly methane (CH4), among other livestock species. Methane has a negative impact on climate; therefore, its reduction is a top priority for a sustainable dairy production system. LÄS MER
5. Temporary Halting of Wind Turbine Rotors toMitigate Effects on Birds
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : This study assesses the viability of temporarily halting wind turbine operations as amitigation measure to protect bird populations during migration periods. Conducted in thenorthern Baltic, it examines the migration patterns, timings, and altitudes of various birdspecies, aiming to identify the most critical times for implementing turbine stoppages.
