1. 1. 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

   University essay from SLU/Dept. of Soil and Environment

   Author : Bella Strid; [2024]
   Keywords : nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

   Abstract : 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. READ MORE

3. 2. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Linnéa Eriksson; [2023-04-20]
   Keywords : soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

   Abstract : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. READ MORE

4. 3. 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

5. 4. 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

6. 5. Impacts of peatland drainage on soil properties : a study of drainage effects on boreal peatlands in northern Sweden

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

   Author : Frederika Klaus; [2022]
   Keywords : Boreal peatlands; Bulk density; Carbon; Greenhouse gas; Isotopes; Nitrogen; Organic matter; Peatlands; Peatland drainage; Peatland restoration;

   Abstract : Peatlands cover approximately 3% of the terrestrial surface on Earth and perform several important ecosystem functions, such as carbon storage and water retention. During the late 19th and early 20th centuries, approximately 2 million hectares of peatlands in Sweden were drained to manage the land for forestry and agriculture. READ MORE
