1. 1. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants

   Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Joel Fransson Forsberg; [2023]
   Nyckelord :Vibrations; Formica ants; Vibrometer; Vibrational signals; Imidacloprid; Before-After-Control-Impact;

   Sammanfattning : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. LÄS MER

3. 2. Quantifying changes in soil bioporosity in subarctic soils after earthworm invasions

   Kandidat-uppsats,

   Författare :Joel Fransson Forsberg; [2021]
   Nyckelord :Biopores; macropores; geoengineering earthworms; X-ray tomography;

   Sammanfattning : Pores provide important hotspots for chemical and biological processes in soils. Earthworm burrows affect the macropore structure and their actions may create new preferential pathways for water and gas flow within soils. This, in turn, indirectly affect plants, nutrient cycling, hydraulic conductivity, gas exchange, and soil organisms. LÄS MER
