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

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

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

    Abstract : 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. READ MORE

  3. 2. Detecting Pollutants Using Vibrations : Laser Doppler Vibrometry as a Non-Invasive Soil Organism Health Monitoring Method

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Kristoffer Wilson; [2023]
    Keywords : Vibrometer; Biotremology; Imidacloprid; Ants;

    Abstract : Due to a lack of in-situ methods capable of detecting sub-lethal effects of pollutants on soil organisms, many polluted environments are not identified prior to pollution-induced changes in the soil fauna. Therefore, there is a need to develop new non-invasive methods to measure the health of soil organisms. READ MORE

  4. 3. Animal personality in ants : Does the red wood ant (Formica rufa) express personality traits?

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Malin Sjöberg; [2023]

This thesis is an ethnographic-inspired study conduct-ed in Danish courts from January to May 2023. READ MORE

  6. 5. Exploring the impact of Formica exsecta ants on soil properties above the tree line in northern Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Filip Pekkari Juto; [2023]
    Keywords : Formica exsecta; ant mounds; soil properties; organic matter content; tundra;

    Abstract : Ants are considered ecosystem engineers due to their effect on the soil properties and their ability to alter the flow of energy and nutrients. Many studies have focused on ants in boreal forests,but few have focused on the ant’s effect on the tundra. READ MORE
