1. 6. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.

   University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

   Author : Hana Faulds; [2023]
   Keywords : Cyanobacteria; pigments; microalgae; wastewater treatment; biotechnology; Technology and Engineering; Biology and Life Sciences;

   Abstract : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

3. 7. Effekt av olika odlingssystem på markstruktur och avkastning : pargårdsstudie i Skåne

   University essay from SLU/Dept. of Soil and Environment

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

   Abstract : 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. READ MORE

4. 8. Fungal Effects on Tree Growth in a Primary Succession

   University essay from SLU/Dept. of Forest Ecology and Management

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

   Abstract : 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. READ MORE

5. 9. Correlation between Normalized Difference Vegetation Index (NDVI) and in vitro organic matter digestibility (IVOMD) of reindeer pasture plants : Korrelation mellan Normalized Difference Vegetation Index (NDVI) och smältbarhet av renbetesväxter i vomvätska in vitro (VOS)

   University essay from SLU/Dept. of Animal Nutrition and Management

   Author : Jannica Helmersson; [2023]
   Keywords : Normalized Difference Vegetation Index; NDVI; in vitro organic matter digestibility; IVOMD; VOS; caribou; Rangifer tarandus; reindeer pasture plants; drone;

   Abstract : Renen livnär sig på många olika betesväxter och den följer växtfenologins utveckling under barmarkssäsongen, vilket resulterar i högkvalitativt foderintag. Levande växtbiomassa kan uppskattas på landskapsnivå genom att använda vegetationsindex som värderar vegetation utifrån spektrala mätningar. READ MORE

6. 10. Legacy effects of temperature alterations on microbial resistance and resilience to drying and rewetting

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Franklin Lee Harris; [2023]
   Keywords : microbial ecology; soil; carbon dynamics; high latitudes; climate change; moisture stress; isotopes; respiration; trait based ecology; soil microbes; Environmental Changes in High Latitudes EnCHIL ; Earth and Environmental Sciences; Biology and Life Sciences;

   Abstract : With warming in soils due to climate change, a series of secondary factors arise, which have multifaceted effects on soil microbial communities. Of these, alterations to soil moisture are among the most crucial to understanding how microbial functions will change in the face of climate change. READ MORE
