1. 16. The development of an acoustic insulation solution using mushroom mycelium as an alternative to synthetic foams

   Magister-uppsats, Jönköping University/JTH, Industridesign

   Författare :Adrián Brito Guerrero de Escalante; [2023]
   Nyckelord :mycelium composites; design thinking; design for emotion; sustainability; acoustic insulation; fungi; mushrooms.;

   Sammanfattning : In the past decades, humanity is facing the consequences of the irresponsible production of plastics and the expansion of industries such as industrial agriculture, Therefore, the development of new sustainable alternative materials has become increasingly popular as a science field. That is the case of mycelium composites, a biodegradable material made out of agricultural and the thread-like roots of mushrooms called mycelium. LÄS MER

3. 17. Reconstructing Past Climate by Using XRF and Loss of Ignition on Loess from Adventdalen, Svalbard : Rekonstruktion av tidigare klimat genom attanvända XRF analys och antändningsförlust på lössavlagringar från Adventdalen, Svalbard

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Albin Andreasson; Noa Lind; [2023]
   Nyckelord :Svalbard; loess soil; XRF; weathering; climate change;

   Sammanfattning : By analyzing the texture, composition and chemical composition of loess soils, the reconstruction ofpast climate regimes is enabled, which can improve our understanding of current and future climatechange. Properties such as grain size and composition, mineralogy, organic matter and chemicalcomposition can provide information about which environmental factors were present during thedeposition of the sediment, which can lead to a detailed picture of the climate history of a site.

4. 18. The potential nitrous oxide emissions in a permanent grassland chronosequence

   Kandidat-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

   Författare :Sandra Lillsjö Kronblad; [2023]
   Nyckelord :nitrous oxide emission; permanent grasslands; denitrification; nitrous; reen house gas; agriculture;

   Sammanfattning : As a part of a larger project (Belowground biodiversity of grasslands – conservation needs and potential to promote sustainable agriculture), this study aims to investigate potential nitrous oxide (N2O) emissions and microbial gene abundances needed for the production (nirS and nirK) and reduction (nosZI and nosZII) of nitrous oxide in soil of permanent grasslands of various age. Thegrasslands have at different times been converted to permanent grasslands and are of interest because of the possibility to shed more light about the passage of time’s affects on the soil microbialcommunities and their activity.

5. 19. Effekt av olika odlingssystem på markstruktur och avkastning : pargårdsstudie i Skåne

   Uppsats för yrkesexamina på grundnivå, SLU/Dept. of Soil and Environment

   Författare :Clara Kihlstrand; Linnéa Frisk; [2023]
   Nyckelord :Markhälsa; reducerad jordbearbetning; ; Conservation Agriculture; plöjning; mellangröda; höstvete; aggregatstabilitet; daggmaskar; pH; dragkraft; infiltration; vattenhalt;

   Sammanfattning : Metoderna att odla jordbruksmark är många. Dessa odlingssystem påverkar markstrukturen och markhälsan på olika vis. Markhälsa är ett begrepp som blir allt viktigare. Under 2023 kommer EU med nya markdirektiv som ska säkra långsiktig odling och hjälpa till att nå klimatmålen. LÄS MER

7. 20. Fungal Effects on Tree Growth in a Primary Succession

   Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :August Hedberg; Julian Säflund; [2023]
   Nyckelord :primary succession; succession; ectomycorrhiza; saprotroph; tree growth; Pinus sylvestris; soil fungi;

   Sammanfattning : In the Boreal zone, ectomycorrhiza is the most common mycorrhiza found among trees and helps with nitrogen and nutrient uptake. Most research on mycorrhiza, its effect, and community development are done on secondary succession (succession in an ecosystem after a disturbance) such as after a clearcut. LÄS MER
